RI.8.7: Evaluating the Advantages and Disadvantages of Different Mediums
In plain English: RI.8.7 is the Common Core grade 8 ELA standard that asks students to evaluate the advantages and disadvantages of using different mediums, such as print or digital text, video and multimedia, to present a particular topic or idea. Students judge what each medium does well and poorly for a given purpose and audience, and back each judgment with evidence. It builds on RI.7.7.
Evaluate the advantages and disadvantages of using different mediums (e.g., print or digital text, video, multimedia) to present a particular topic or idea.
Common Core State Standards for English Language Arts & Literacy · Domain: Reading Standards for Informational Text · Cluster: Integration of Knowledge and Ideas · Official standard
Students evaluate the advantages and disadvantages of using different mediums to present one topic. A medium (plural mediums or media) is the form a presentation takes: print text, digital text, video or multimedia. Grade 8 asks for more than "the video was more interesting." Students name what a medium does well for this topic (an advantage), what it does poorly, leaves out or makes harder (a disadvantage), and then weigh the two for a particular purpose and audience, with evidence from each presentation.
The topic is the eruption of Mount Vesuvius in 79 CE, which buried the Roman town of Pompeii. The print text is Pliny the Younger's letter to the historian Tacitus, in an English translation: Pliny saw the eruption cloud himself and learned the rest of his uncle's story from people who were there. The other mediums are presented in words, so no screen or internet connection is needed: a storyboard for a short online video, a plan for an interactive museum website and a digital article with links and comments, all invented for this page. The teacher models with the letter and the video (Passages 1 and 2), pairs evaluate the museum website (Passage 3), and students work alone on the digital article (Passage 4) for the quiz. The homework pairs Pliny's account of his own escape (Passage 5) with a podcast plan (Passage 6). All six passages are printed in the lesson plan.
Learning Objectives
By the end of this lesson, students will be able to:
Identify the medium of a presentation (print text, digital text, video or multimedia) and the tools it uses, such as pictures, sound, links and on-screen text
Explain at least one advantage and one disadvantage of a medium for presenting a particular topic, with evidence from the presentation
Evaluate which medium best presents a topic for a stated purpose and audience, weighing advantages against disadvantages
Build an original table or chart that compares mediums on clear criteria and explain the ratings
Prior Knowledge Required
Students should already be comfortable with:
Comparing a text to an audio, video or multimedia version of it, analyzing how each medium portrays the subject RI.7.7
Integrating information presented in different media or formats RI.6.7
Citing textual evidence with a passage and paragraph number RI.8.1
Using context to work out the meaning of an unfamiliar word
"Think of something you learned how to do from a video, such as a recipe, a game move or a bike repair. Would a page of written steps have been better or worse? Give one reason each way."
Take four or five answers and sort them on the board into two columns, "the video did this better" and "the page would do this better." Students usually find that video wins at showing motion and the page wins at letting you go back, skim and copy exact amounts. Name the two columns: advantages (what a medium does well) and disadvantages (what it does poorly or leaves out). Tell students that RI.8.7 asks them to do this on purpose, for one topic presented in several mediums, and to decide which medium fits which job.
Direct Instruction15 minutes
Teach the terms and leave them on the board:
Medium: the form a presentation takes. The standard names four: print text (words on paper, such as a book or letter), digital text (words on a screen, which can include links, search and updates), video (moving pictures with sound) and multimedia (several forms combined, such as text, pictures, audio, maps and things the user can click).
Advantage: something a medium does well for this topic and this audience.
Disadvantage: something it does poorly, leaves out, gets wrong or makes harder.
Evaluate: judge with reasons. An evaluation names the purpose (what the presentation is for) and the audience (who it is for), and weighs the advantages against the disadvantages.
Reenactment: a scene acted out to show what may have happened. Storyboard: the plan for a video, shot by shot: what viewers see, hear and read on screen.
Questions to ask of any medium
Question
What to look for
Accuracy
Does it keep the facts straight and mark what is guessed or acted out?
Detail
Does it give exact words, numbers and small details, or only the big picture?
Showing
Can it show size, place, motion and sound, or must the audience imagine them?
Control
Can the audience slow down, go back and skim, or does the medium set the pace?
Access
What does the audience need: a screen, an internet connection, sound, good eyesight or hearing?
Focus
Does it keep attention on the topic, or pull the audience toward other things?
Introduce the topic. In 79 CE, Mount Vesuvius, a volcano on the Bay of Naples in southern Italy, erupted and buried the Roman towns of Pompeii and Herculaneum. Pliny the Younger, then a teenager, watched from the naval town of Misenum, across the bay. His uncle, Pliny the Elder, commanded the Roman fleet there and was a famous scientific writer. More than twenty-five years later, the historian Tacitus asked the younger Pliny how his uncle had died, and Pliny answered in two letters. Pliny saw the cloud himself; what happened to his uncle near the volcano he learned from people who were with him. Passage 1 comes from the first letter, in an English translation revised in the 1800s. Words to know: fleet (a group of warships), desired him to observe (asked him to look at), a rising ground (a small hill), likening (comparing), occasioned (caused), impelled (pushed), impregnated (filled), cinders (small bits of burned rock), pumice-stones (light volcanic rock full of air bubbles), obstructed (blocked), defence (British spelling of defense) and alleviated (made less bad). Read Passage 1 aloud. Then read Passage 2, a storyboard for a short online video about the same eruption, invented for this page.
1He was at that time with the fleet under his command at Misenum. On the 24th of August, about one in the afternoon, my mother desired him to observe a cloud which appeared of a very unusual size and shape. He had just taken a turn in the sun and, after bathing himself in cold water, and making a light luncheon, gone back to his books: he immediately arose and went out upon a rising ground from whence he might get a better sight of this very uncommon appearance. A cloud, from which mountain was uncertain, at this distance (but it was found afterwards to come from Mount Vesuvius), was ascending, the appearance of which I cannot give you a more exact description of than by likening it to that of a pine tree, for it shot up to a great height in the form of a very tall trunk, which spread itself out at the top into a sort of branches; occasioned, I imagine, either by a sudden gust of air that impelled it, the force of which decreased as it advanced upwards, or the cloud itself being pressed back again by its own weight, expanded in the manner I have mentioned; it appeared sometimes bright and sometimes dark and spotted, according as it was either more or less impregnated with earth and cinders.
[...]
2He was now so close to the mountain that the cinders, which grew thicker and hotter the nearer he approached, fell into the ships, together with pumice-stones, and black pieces of burning rock: they were in danger too not only of being aground by the sudden retreat of the sea, but also from the vast fragments which rolled down from the mountain, and obstructed all the shore.
[...]
3They went out then, having pillows tied upon their heads with napkins; and this was their whole defence against the storm of stones that fell round them. It was now day everywhere else, but there a deeper darkness prevailed than in the thickest night; which however was in some degree alleviated by torches and other lights of various kinds.
Pliny the Younger, translated by William Melmoth, revised by F. C. T. Bosanquet, Passage 1: Letter LXV, To Tacitus, on the death of Pliny's uncle (three excerpts; the sentences between them are left out and marked [...]) (1746; this edition 1909). Public domain (published 1909). Source text.
1Shot 1 (0:00-0:20). Picture: a drone flies over the blue Bay of Naples toward Mount Vesuvius on a sunny day. Sound: low, slow drums. On-screen text: "Bay of Naples, Italy. Almost 2,000 years ago..."
2Shot 2 (0:20-1:05). Picture: a computer animation shows a gray column shooting out of the mountain and spreading at the top like an umbrella. A scale bar beside it climbs to 30 kilometers, next to a tiny airliner flying at 11 kilometers. Narrator: "Scientists estimate that the column rose about 30 kilometers. Across the bay, a teenager named Pliny watched it. He wrote that it looked like a pine tree."
3Shot 3 (1:05-1:55). Picture: a reenactment. Actors in Roman costume stand on a wooden ship while gray stones rain onto the deck. A small label in one corner reads "Reenactment." Sound: stones clattering, waves, shouting. An actor playing a sailor yells, "The gods are angry! Turn back!" An actor playing Pliny's uncle answers, "Fortune favors the brave."
4Shot 4 (1:55-2:45). Picture: an animated map of the bay. A red dot marks the volcano. Arrows show the wind carrying ash to the southeast, over Pompeii and Stabiae, while Misenum stays clear. A line from Misenum to the volcano is labeled "about 30 km." Narrator: "The wind decided who would be buried."
5Shot 5 (2:45-3:35). Picture: Dr. Elena Russo speaks on camera at the edge of the crater. Caption: "Dr. Elena Russo, volcanologist." She says: "We still call this kind of eruption Plinian, after Pliny, because his letters describe it so clearly. Every time we study a new eruption, we are reading over his shoulder."
6Shot 6 (3:35-4:00). Picture: modern Naples at night, with the dark shape of Vesuvius behind the city lights. On-screen text: "Vesuvius last erupted in 1944. Millions of people live around the bay today." The video ends with three small pictures under the words "Watch next."
7Below the video, the description box lists one source, "Pliny the Younger, Letters 6.16 and 6.20," and says that captions are available in English and Italian.
Written for this page, Passage 2: Storyboard for an online video, "Vesuvius: The Day the Sky Went Dark" (an invented 4-minute video written for this page; the expert is invented). Original passage written for this page.
Print: an advantage
Pliny cannot describe the cloud "more exact" than "by likening it to that of a pine tree," and he guesses at its cause: "occasioned, I imagine, either by a sudden gust of air that impelled it" (Passage 1, paragraph 1). What does the print medium do well here?
Result: Print keeps the eyewitness's exact words, including his doubt. "I imagine" tells the reader that the cause is Pliny's guess, not a fact, and a reader can reread the long sentence as slowly as needed and quote it exactly in a report. The advantage is precision: nothing stands between the reader and the witness except the translator.
Print: a disadvantage
Pliny writes that "the cinders, which grew thicker and hotter the nearer he approached, fell into the ships, together with pumice-stones, and black pieces of burning rock" (Passage 1, paragraph 2). What is harder for a reader of the print version?
Result: The reader has to build the scene alone. The sentence gives no picture of pumice, no sense of how big the stones were or how fast they fell, and no sound. A reader who has never seen a volcano, or who does not know the word "pumice," may miss how dangerous the moment was. The disadvantage is that print depends on the reader's vocabulary and imagination.
Video: an advantage
In Shot 2 of Passage 2, "A scale bar beside it climbs to 30 kilometers, next to a tiny airliner flying at 11 kilometers." What can the video do here that the letter cannot?
Result: The video shows size at a glance. Pliny says only that the cloud "shot up to a great height"; the animation puts a number on it and compares it with something viewers know, an airliner, which looks tiny beside the column. For an audience that needs to grasp how big the eruption was, this is a clear advantage of video.
Video: a disadvantage
In Shot 3, "An actor playing a sailor yells, 'The gods are angry! Turn back!' An actor playing Pliny's uncle answers, 'Fortune favors the brave.'" A small label reads "Reenactment." What problem does this create?
Result: The uncle's words come from Pliny's letter, in a part not printed here. The letter says only that the pilot advised him to turn back; the sailor's shouted line about angry gods is invented. On screen, both lines sound equally real, and the small corner label is easy to miss. A viewer cannot tell which words come from the source and which were added for drama. The disadvantage is that video can blend fact and invention without marking the difference.
Weighing both for a purpose
A student is writing a report on what eyewitnesses said about the eruption. Another is making a presentation to show fifth graders how big the eruption was. Which of the two mediums in Passages 1 and 2 fits each purpose better?
Result: For the report, the print letter is stronger: it gives exact words to quote and marks what Pliny guessed. The video's reenactment would be a weak source, because its dialogue is partly invented. For the fifth graders, the video is stronger: its scale bar and animation show size quickly. Its invented dialogue is a real disadvantage, but it matters less for this purpose. The better medium depends on the purpose and the audience.
Name it, show it, weigh it. Show Diagram 1 and model three moves with the examples: name the advantage or disadvantage; point to the words, shot or feature that shows it; weigh it for a purpose and an audience. Stress that Diagram 1 is one reasonable judgment and that students may rate differently if they give reasons. Give students a frame: "For [purpose and audience], has the advantage of ___, as shown by ___. Its disadvantage is ___. Overall, it is a strong / mixed / weak choice because ___."
Guided Practice15 minutes
Read Passage 3 aloud: a plan for an interactive museum website about the same eruption, invented for this page. Interactive means the visitor clicks, scrolls, zooms or drags to control what appears. Words to know: panel (one section of the screen), carbonized (turned to charcoal by heat), 3D model (a picture of an object that can be turned to see it from every side), layer (information that can be shown or hidden on a map) and reconstruction (a picture or model of how something probably looked, made by experts).
1Opening screen. A photograph of the ruins of Pompeii fills the screen, with Vesuvius behind them. The title fades in: "Under the Ash: Hour by Hour." A button says "Start the timeline." A note at the bottom says that the feature works best on a computer or tablet with the sound turned on.
2The timeline. Visitors scroll down through ten panels, one for each stage of the eruption. Each panel has a clock showing the hour, two or three sentences of text and one picture. Panel 1 shows the cloud rising at about one in the afternoon, the hour Pliny gives. Its picture is a drawing of the cloud as seen from Misenum, labeled "Artist's reconstruction."
3Listen. On four panels, a speaker button plays an actor reading a short part of Pliny's letters, about 30 seconds each. The words appear on the screen as the actor reads them. A fifth recording, in which a scientist explains how pumice forms, has no written version.
4Look closer. Panel 6 shows a photograph of a real loaf of bread that was found carbonized (turned to charcoal) in Pompeii. Visitors can zoom in until they see the lines baked into its crust. On Panel 7, a 3D model of a Pompeii house turns when a visitor drags it with a finger or a mouse. Its label says "Digital reconstruction, based on the excavated house."
5Map layers. A map of the bay has buttons for three layers: towns, wind direction and ash depth. Turning on the ash layer colors the land southeast of the volcano dark gray. The map has no scale showing distances.
6Check yourself. The last panel is a five-question quiz that tells visitors right away whether each answer is correct. A "Sources" link opens a list of eight books and articles. On a phone, each panel takes several seconds to load, and every panel has a "Share" button and a "More videos" strip along the side.
Written for this page, Passage 3: Plan for an interactive museum website, "Under the Ash: Hour by Hour" (an invented multimedia feature written for this page). Original passage written for this page.
Pairs fill in a copy of Diagram 2, the medium evaluation card, for Passage 3. The purpose and audience are given: a museum wants to help seventh and eighth graders understand what happened in Pompeii during the eruption. Pairs answer the three questions below, then share. Teacher notes:
The recordings. What does the "Listen" feature do well, and for whom does it fail? Teacher note: hearing Pliny's words read aloud, with "The words appear on the screen as the actor reads them," helps students who find old translations hard to read and still keeps the exact words. But the fifth recording "has no written version," so a visitor who is deaf or hard of hearing, or who has the sound off, loses that information.
The bread. Why might the museum put a photograph of a real loaf of bread on Panel 6? Teacher note: an everyday object that a visitor can zoom in on, down to "the lines baked into its crust," makes the ordinary life of the town real in a way a sentence cannot. This is an advantage of multimedia: real objects, shown up close.
The map. What is missing from the map, and why does it matter? Teacher note: "The map has no scale showing distances." The ash layer shows where ash fell, but visitors cannot tell how far Pompeii is from the volcano, which is part of what the museum wants them to understand.
Independent Practice15 minutes
Students read Passage 4 on their own: a digital article about the eruption, invented for this page, as it would appear on a history website. Words marked "(link)" are hyperlinks: words a reader can click to open another page. Other words to know: encyclopedia (a large reference work with articles on many subjects), archaeologists (scientists who study past people from the things they left behind) and convinced (sure). They answer the quiz with Passages 1-4 open, filling in a fresh Diagram 2 card for Passage 4 first if they wish.
1Updated March 3, 2026. 4-minute read. Text size: A / A+ / A++. Button: "Listen to this article" (read aloud by a computer voice).
2In 79 CE, Mount Vesuvius, a volcano on the Bay of Naples in Italy, erupted and buried the Roman towns of Pompeii (link) and Herculaneum (link) under ash and stone. We know how the eruption looked partly because of two letters by Pliny the Younger (link), who watched it from the town of Misenum, across the bay.
3Pliny wrote the letters more than twenty-five years later, for the historian Tacitus (link), who had asked how Pliny's uncle died. His uncle, Pliny the Elder, commanded the Roman fleet at Misenum and wrote a huge encyclopedia called Natural History (link). He sailed toward the volcano to help people escape, and he died on the shore at Stabiae.
4The letters give the date as August 24. In 2018, however, archaeologists working at Pompeii found words written in charcoal on a wall, with a date in the middle of October (link to the news report). Because charcoal writing fades fast, some experts now think the eruption came in the fall of 79 CE. Others are not convinced. (This paragraph was added on March 3, 2026.)

6Comments (212). One reader asks: "My teacher said the whole town was frozen in one second. Is that true?" A site editor replies: "Not quite. Pliny's letters describe events that went on into the next day. See our timeline (link)."

Closure5-10 minutes
Exit ticket: (1) Name one advantage of video that print text cannot match, and one advantage of print that video cannot match, using Passages 1 and 2. (2) Finish the sentence: "The best medium for a topic depends on ___ because ___."
Teacher note on the sources and the facts. Passages 1 and 5 are an old English translation of Latin letters, so the wording is formal and some spellings are British ("defence," "recognise," "wilfully"). The letters describe fear and, elsewhere, the uncle's death; the excerpts printed here leave out the death scene, but Passage 5 describes a panicking crowd, so prepare students who may find disaster accounts upsetting. Passages 2, 3, 4 and 6 are invented for this page: the video, the website, the article, the podcast and Dr. Elena Russo do not exist. The facts they report are real: the eruption of 79 CE, Pliny's letters to Tacitus, the name "Plinian" for this type of eruption, carbonized bread from Pompeii, the 1944 eruption, and the charcoal writing found at Pompeii in 2018, which led some archaeologists to argue for a date in the fall of 79 CE instead of August 24. The column height of about 30 kilometers is an estimate by volcanologists. In Passage 5, Pliny refers to "the final endless night," a belief of his time that the world would end in darkness.
For homework: students read Passage 5, from Pliny's second letter, in which he describes his own escape from Misenum with his mother the next morning, and Passage 6, a plan for a podcast episode about the same scene, invented for this page. Words to know: high-road (main road), lamenting (crying out in sorrow), augmented (added to), wilfully (on purpose), forerunner (a sign of something coming), immersed (sunk into), dissipated by degrees (cleared little by little), lurid (pale and strange-looking), eclipse (when the Moon blocks the Sun), transcript (a written copy of what was said) and sound designer (the person who adds sound effects and music).
1The ashes now began to fall upon us, though in no great quantity. I looked back; a dense dark mist seemed to be following us, spreading itself over the country like a cloud. "Let us turn out of the high-road," I said, "while we can still see, for fear that, should we fall in the road, we should be pressed to death in the dark, by the crowds that are following us."
2We had scarcely sat down when night came upon us, not such as we have when the sky is cloudy, or when there is no moon, but that of a room when it is shut up, and all the lights put out. You might hear the shrieks of women, the screams of children, and the shouts of men; some calling for their children, others for their parents, others for their husbands, and seeking to recognise each other by the voices that replied; one lamenting his own fate, another that of his family; some wishing to die, from the very fear of dying; some lifting their hands to the gods; but the greater part convinced that there were now no gods at all, and that the final endless night of which we have heard had come upon the world. Among these there were some who augmented the real terrors by others imaginary or wilfully invented. I remember some who declared that one part of Misenum had fallen, that another was on fire; it was false, but they found people to believe them.
3It now grew rather lighter, which we imagined to be rather the forerunner of an approaching burst of flames (as in truth it was) than the return of day: however, the fire fell at a distance from us: then again we were immersed in thick darkness, and a heavy shower of ashes rained upon us, which we were obliged every now and then to stand up to shake off, otherwise we should have been crushed and buried in the heap.
[...]
4At last this dreadful darkness was dissipated by degrees, like a cloud or smoke; the real day returned, and even the sun shone out, though with a lurid light, like when an eclipse is coming on. Every object that presented itself to our eyes (which were extremely weakened) seemed changed, being covered deep with ashes as if with snow.

Differentiation Strategies
For Struggling Students
Give a card with the six questions from the Direct Instruction table and one example answer for each, to keep beside the passages
Read Passage 1 aloud a second time and have students sketch the pine-tree cloud before discussing what the print version leaves them to imagine
For Guided Practice, assign only the Advantages box of Diagram 2 first, then add the Disadvantages box with a partner
For Advanced Students
Ask them to rewrite Shot 3 of Passage 2 so that it keeps the drama but no longer mixes invented lines with Pliny's words, and explain the change
Have them design a fifth medium for the topic, such as a comic strip or a museum audio tour, and write its advantages and disadvantages for two different audiences
Ask them to argue in a short paragraph whether any single medium could present the eruption well for every audience, or whether some topics always need more than one
Assessment Guidance
What to Look For
Check that each answer names the medium, states an advantage or disadvantage in specific terms, points to the words, shot or feature that shows it, and weighs it for a purpose and an audience. The strongest answers admit what the chosen medium does poorly and explain why its advantages still matter more for that purpose. A common weak answer judges by preference alone ("the video is more fun"); ask "Better for whom, and for what?" and "Which shot or sentence shows that?"

Classroom Activities
3 Activities
1
Purpose Cards
15 minPairs
Each pair gets eight purpose cards, written for this activity. Each card names an audience and a job. Pairs choose the medium that fits best (print text, digital text, video or multimedia) and write one advantage and one disadvantage of their choice on the back.
The Eight Cards
A family on a camping trip with no phone signal wants to read about the stars they can see.
A soccer coach wants to teach a new passing drill to players who learn by watching.
A science class needs to look up many related facts about sharks quickly, jumping from one question to the next.
A museum visitor wants to explore a shipwreck at their own pace, choosing what to look at.
A student must quote a president's exact words in a history essay.
A viewer who is deaf wants to learn how bees build a hive.
A town wants every household, including people without computers, to know the new recycling rules.
A teacher wants students to compare the sizes of the planets.
Procedure
Pairs choose a medium for each card and write one advantage and one disadvantage (8 minutes)
Two pairs compare answers and must agree on the card where they chose differently (5 minutes)
Answer key for the teacher, sample answers (other choices can be right with good reasons): 1, print (works with no signal; no pictures of the sky unless drawn); 2, video (shows motion; players cannot easily look up one step); 3, digital text (search and links make it fast to jump between facts; the reader must judge which sites to trust); 4, multimedia (the visitor controls the order; it can be hard to follow one story); 5, print or digital text of the speech (exact words; no tone of voice); 6, video with captions, or multimedia with text (shows the hive being built; fails if captions are missing); 7, print, such as a mailed flyer (reaches everyone; cannot show how to sort items unless it has pictures); 8, multimedia (a model or animation can show size to scale; needs a screen)
Discussion Questions
Card 5 and card 3 both call for text. Why does one work better on paper and the other on a screen?
Which card was hardest to decide, and what would change your answer?
Modification
For students who need support, give only cards 1, 2, 3 and 4, one for each medium, and discuss the first card together before pairs try the rest.
2
One Fact, Four Mediums
15 minGroups of 3-4
Each group gets one fact card about Vesuvius and plans how the fact would be presented in all four mediums. Then the group decides what each medium gains and loses.
The Four Fact Cards
Pompeii lies about 10 kilometers southeast of Vesuvius and was buried under several meters of ash and pumice.
Vesuvius last erupted in 1944, during World War II.
Excavations at Pompeii began in 1748 and still go on today.
Scientists now call a tall, explosive eruption like the one of 79 CE a "Plinian" eruption.
Procedure
On chart paper divided into four boxes, the group writes two sentences of print text, a digital text with two links, a one-shot video plan (picture, sound, words on screen) and a multimedia plan with at least two features
Under each box, the group writes one thing the medium does well for their fact and one thing it does poorly
Groups circle the box they think works best for a class of sixth graders and explain why in one sentence
Discussion Questions
Which fact was easiest to present in print, and which needed pictures? Why?
Did any group's video or multimedia plan add something that is not in the fact card? Is that a problem?
3
Four Corners
10 minWhole class
The four corners of the room are labeled Print Text, Digital Text, Video and Multimedia. The teacher reads a purpose statement; students walk to the corner of the medium they would choose and defend it.
Purpose Statements
"Help a visitor to Naples understand why the town is still in danger from Vesuvius."
"Give a history class the exact words of someone who lived through a disaster."
"Let students explore Pompeii's streets as if they were walking through them."
Procedure
After each statement, each corner has one minute to agree on its best advantage
Then each corner must name one disadvantage of its own medium before anyone else can name it
Students may move corners if another group's reasons convince them; ask the movers what changed their minds
Variation
For a harder version, the teacher adds an audience to each statement (a young child, a visitor who does not read English well, a scientist) and students re-sort.

Diagrams & Visual Aids
2 diagrams
Diagram 1: One Topic, Two Mediums, a Sample Rating
An original chart rating Passage 1 (Pliny's letter in print) and Passage 2 (the online video) on six questions about presenting the eruption. It is one reasonable judgment for a general audience, not an answer key; the ratings change with the purpose and the audience.
Diagram 2: Medium Evaluation Card
Pairs copy this card in Guided Practice for Passage 3. They name the medium, the topic, the purpose and the audience, list advantages and disadvantages with evidence, then write a verdict that weighs the two.

Homework Assignment
~30 min
RI.8.7 Homework: Pliny's Escape in Print and in Sound
Directions: Read Passage 5 and Passage 6 at the end of the lesson plan (in Closure). Cite them by passage and paragraph, for example (Passage 5, paragraph 2). For every answer, name the medium, state the advantage or disadvantage, and point to the words or feature that shows it. Answer Problems 1-4 in 3-5 sentences each.
Part 1: The Print Account (Problems 1-2)
Pliny says the darkness was "not such as we have when the sky is cloudy, or when there is no moon, but that of a room when it is shut up, and all the lights put out" (Passage 5, paragraph 2). Explain one advantage of print for presenting this moment. Then explain why a video might have trouble presenting it.
In paragraph 2, Pliny reports that some people "declared that one part of Misenum had fallen, that another was on fire; it was false, but they found people to believe them." Explain how the print letter separates rumor from fact here. Is this an advantage of Pliny's medium, a letter written years later, or could a live video from that day have done it as well? Explain.
Part 2: The Podcast (Problems 3-4)
In Passage 6, the sound designer adds "footsteps, a baby crying, people calling out names" behind the actor's voice. Pliny wrote that people were "seeking to recognise each other by the voices that replied" (Passage 5, paragraph 2). Evaluate one advantage and one disadvantage of presenting the crowd scene in sound.
Evaluate the podcast for two listeners: a student who wants to take notes for a report, and a student who is hard of hearing. Use at least three details from Passage 6, such as the speed setting, the transcript and the advertisement.
Part 3: Build and Defend (Problems 5-6)
Build an original table that rates three mediums for presenting Pliny's escape: the print letter (Passage 5), the podcast (Passage 6) and one other medium you design (a video or a multimedia feature). Use four questions from the Direct Instruction table as rows, rate each medium from 1 to 3, and write one sentence under the table explaining your highest and lowest rating.
Write a paragraph of 6-8 sentences: A school is choosing one medium to teach sixth graders what Pliny and his mother lived through on the morning of the escape. Which medium should it choose? Evaluate at least one advantage and one disadvantage of your choice and of one other medium, with evidence from Passages 5 and 6, and explain why your choice's advantages matter more for this purpose.

0 of 20 answered · 0 correct
Question 1 of 20 · Multiple Choice
Which of these is an example of multimedia?
Answer: C
Choice C combines several forms, text, an interactive map, a photograph and audio, so it is multimedia. Choice A is print text only. Choice B uses a single form, sound. Choice D mistakes the screen for the medium: a scanned letter shown online is still one form, a picture of a written text, with nothing added.
Question 2 of 20 · Multiple Choice
A student wants to learn the steps of a science experiment that she will do at home next week, with her notes beside her. What is one advantage of a printed set of steps over a video for her purpose?
Answer: A
Choice A names what print does well: the reader controls the pace and can jump straight to one step. Choice B is an advantage of video, not print. Choice C describes sound, which a printed page cannot give. Choice D confuses print with digital text; a printed page cannot update itself.
Question 3 of 20 · Multiple Choice
A teacher shows a five-minute video about how volcanoes form. Which is a disadvantage of video for students who must take notes on it?
Answer: D
Choice D is a real disadvantage for note-takers: the medium, not the viewer, controls the speed, unless the teacher pauses and rewinds. Choices A and C are advantages of video, not disadvantages. Choice B mistakes a tool for a problem; music may distract some viewers, but it does not stop anyone from taking notes.
Question 4 of 20 · Multiple Choice
Pliny writes, "A cloud, from which mountain was uncertain, at this distance (but it was found afterwards to come from Mount Vesuvius), was ascending" (Passage 1, paragraph 1). What advantage of his print account does this sentence show?
Answer: B
The words in parentheses mark a later fact, "found afterwards," inside an account of what Pliny could see "at this distance" at the time. Keeping the two apart is an advantage of a careful written account. Choice A confuses description with a picture. Choice C describes sound, which print cannot give. Choice D is wrong: Pliny gives no height, only "a great height."
Question 5 of 20 · Multiple Choice
Pliny writes, "He was at that time with the fleet under his command at Misenum" (Passage 1, paragraph 1). What disadvantage does the print letter have for a reader today who has never seen the Bay of Naples?
Answer: A
Pliny names Misenum and, in paragraph 1, Mount Vesuvius, but a reader who does not know the bay cannot picture where they lie; a map would do that at once. Choice B is wrong: the excerpt gives almost no numbers. Choice C is wrong: exact words are what make print easy to quote. Choice D does not fit print, which never moves on by itself.
Question 6 of 20 · Multiple Choice
In Shot 4 of Passage 2, "Arrows show the wind carrying ash to the southeast, over Pompeii and Stabiae, while Misenum stays clear." What is the main advantage of presenting this in an animated map?
Answer: C
The map shows places and wind together, so viewers see the pattern of the ashfall in a few seconds, which Passage 1 never shows. Choice A describes print, the strength of Passage 1. Choice B is wrong: the shot is an animation with a narrator, not a page of labels to study. Choice D has nothing to do with the map; the video never gives a date.
Question 7 of 20 · Multiple Choice
Shot 4 ends with the narrator saying, "The wind decided who would be buried." What is a disadvantage of this line?
Answer: B
Videos often need short, memorable lines, but this one turns a complicated event into one cause. Distance from the volcano mattered too: Herculaneum, close to the volcano on its western side, was buried as well, by flows of hot gas and rock. Choice A is wrong: it is one short sentence. Choice C is wrong: the line is the narrator's, not Pliny's. Choice D is wrong: the line contains no numbers.
Question 8 of 20 · Multiple Choice
In Shot 5 of Passage 2, a volcanologist says, "We still call this kind of eruption Plinian, after Pliny, because his letters describe it so clearly." What does this shot add that Passage 1 alone cannot?
Answer: A
Shot 5 connects the old letter to modern science through an expert's voice, something the letter could not do. Choice B describes Passage 1 itself, not what the video adds. Choice C belongs to Shot 4, and Choice D to Shot 3.
Question 9 of 20 · Multiple Choice
Below the video, "the description box lists one source, 'Pliny the Younger, Letters 6.16 and 6.20.'" Which statement best evaluates this?
Answer: D
Pliny died long before 1944 and never measured the cloud, so those facts must come from other sources the video does not list. Viewers cannot check them. Choice A is the reverse of the truth: naming sources helps. Choice B is false for the same reason Choice D is true. Choice C guesses about viewers instead of evaluating the medium.
Question 10 of 20 · Multiple Choice
Passage 3 labels one picture "Artist's reconstruction" and the 3D house "Digital reconstruction, based on the excavated house." What is the advantage of these labels?
Answer: B
A reconstruction is made by experts, not photographed, and the labels say so plainly, so visitors can tell it apart from the real bread on Panel 6. Choice A confuses labels with loading speed. Choice C describes the "Listen" feature. Choice D is impossible: there were no photographs in 79 CE, and the labels say the pictures are reconstructions.
Question 11 of 20 · Multiple Choice
Passage 3 says the feature "works best on a computer or tablet with the sound turned on" and that on a phone "each panel takes several seconds to load." Which evaluation fits these details?
Answer: C
Both details show that the feature depends on equipment, a large screen, sound and a fast connection, that not every visitor has. Choice A ignores the passage. Choice B is impossible: a website needs a screen. Choice D turns a clear problem into a virtue with no support in the passage.
Question 12 of 20 · Multiple Choice
Passage 3 has "ten panels, one for each stage of the eruption," and "Each panel has a clock showing the hour." What does this design do well for the topic?
Answer: A
A timeline with clocks turns the eruption into a sequence a visitor can follow step by step. Choice B is wrong: the recordings are short parts, "about 30 seconds each." Choice C is wrong: "The map has no scale showing distances." Choice D describes nothing in the timeline itself.
Question 13 of 20 · Multiple Choice
Passage 4 lists "Related articles: 'Ten Volcanoes You Can Visit' (link). 'The Five Best Disaster Movies' (link). Advertisement: 'Book your Naples tour today!'" What disadvantage of digital text do these show?
Answer: D
The related links and the advertisement lead away from the history of the eruption, a problem on many websites that earn money from clicks. Choice A is false: digital text can include pictures. Choice B is false: a web page can be as long as the writer likes. Choice C confuses the optional "Listen" button with a requirement.
Question 14 of 20 · Multiple Choice
Passage 4 offers "Text size: A / A+ / A++" and a button to "Listen to this article." Whom does this help most, and why?
Answer: B
Both features change how the reader receives the same words: bigger letters, or a computer voice. That is an access advantage of digital text. Choice A describes a different feature, the links. Choice C confuses these buttons with the comments. Choice D is about printing, which the passage never mentions.
Question 15 of 20 · Short Answer
Pliny writes that the group "went out then, having pillows tied upon their heads with napkins; and this was their whole defence against the storm of stones that fell round them" (Passage 1, paragraph 3). Explain one advantage print has for presenting this moment and one disadvantage.
Model answer: An advantage is that print carries the writer's judgment along with the fact. Pillows tied on with napkins are a small, ordinary detail, and the words "this was their whole defence" tell the reader how helpless the group was; a picture could show the pillows but not Pliny's comment on them. A disadvantage is that the reader has to imagine the "storm of stones": how large the stones were, how hard they fell and how loud they were, with no picture or sound to help. Rubric: 2 points for one advantage and one disadvantage, each tied to the quoted words; 1 point for only one of them; 0 points otherwise.
Question 16 of 20 · Short Answer
Passage 2 ends with Shot 6: modern Naples at night and the words "Vesuvius last erupted in 1944. Millions of people live around the bay today," followed by three small pictures under "Watch next." Evaluate one advantage and one disadvantage of ending the video this way.
Model answer: An advantage is that the ending connects the ancient eruption to the present in a few seconds: the city lights under "the dark shape of Vesuvius" show viewers that the danger is real today, something Pliny's letter could not show. A disadvantage is that the "Watch next" pictures appear the moment the video ends, inviting viewers to jump to another video before they have thought about what they saw. Rubric: 2 points for one advantage and one disadvantage of the ending, each tied to details of Shot 6; 1 point for only one; 0 points otherwise.
Question 17 of 20 · Short Answer
Passage 3 ends with a five-question quiz that "tells visitors right away whether each answer is correct," and says every panel has "a 'Share' button and a 'More videos' strip along the side." Evaluate these two features for the museum's purpose of helping students understand what happened in Pompeii.
Model answer: The quiz is an advantage: instant feedback lets students check what they understood and go back to a panel they missed, which a printed book cannot do. The "Share" buttons and "More videos" strip are a disadvantage, because they sit beside every panel and invite students to leave the story before it is finished. For this purpose, the quiz helps more than the side strip hurts, but the museum could move the strip to the last panel. Rubric: 2 points for evaluating both features for the stated purpose, with a weighed judgment; 1 point for evaluating one feature; 0 points otherwise.
Question 18 of 20 · Short Answer
Passage 4 says, "(This paragraph was added on March 3, 2026.)" Passage 1 gives the date as "the 24th of August." Explain what this shows about an advantage of digital text and a disadvantage of print.
Model answer: Digital text can be updated when new evidence appears. After archaeologists found the charcoal writing in 2018, the website added a paragraph explaining that some experts now think the eruption came in the fall, and it tells readers when the change was made. A printed letter cannot change: Passage 1 still says "the 24th of August," and a reader of the print version alone would not learn that the date is now debated. Rubric: 2 points for the updating advantage and the fixed-print disadvantage, with both dates or quotations; 1 point for only one; 0 points otherwise.
Question 19 of 20 · Short Answer
Evaluate the comment section at the end of Passage 4. Give one advantage and one disadvantage, and quote the passage.
Model answer: An advantage is that readers can ask questions and get answers: a reader asks whether "the whole town was frozen in one second," and "A site editor replies" with a correction and a link to the timeline. A disadvantage is that comments are written by anyone, so a false idea like the one the reader heard can spread before someone corrects it, and with "Comments (212)" not every one will be checked. Rubric: 2 points for one advantage and one disadvantage, each with a quotation; 1 point for only one; 0 points otherwise.
Question 20 of 20 · Short Answer
A teacher wants students to understand what everyday life in Pompeii was like just before the eruption. Which medium on this page would you choose: the print letter (Passage 1), the video (Passage 2), the museum website (Passage 3) or the digital article (Passage 4)? Evaluate one advantage and one disadvantage of your choice, and one disadvantage of another medium, using evidence from the passages.
Model answer (one of several good answers): The museum website in Passage 3 is the best choice. It shows real things from the town: visitors can zoom in on a loaf of bread "found carbonized (turned to charcoal) in Pompeii" and turn a 3D model of a Pompeii house, so students see how people lived, not only how they died. Its disadvantage is that it "works best on a computer or tablet with the sound turned on," so students with only a phone get a slower, weaker version. The print letter would be a weak choice for this purpose: Pliny wrote from Misenum, across the bay, and Passage 1 says nothing about daily life in Pompeii. An answer that chooses another medium can earn full credit if it is supported the same way. Rubric: 2 points for a clear choice, an advantage and a disadvantage of it, and a disadvantage of another medium, each with evidence; 1 point if one part is missing; 0 points otherwise.

Frequently Asked Questions
10 Questions
What does RI.8.7 mean?
It means eighth graders judge how well different forms of presentation work for one topic. The standard asks students to "evaluate the advantages and disadvantages of using different mediums," and it names print or digital text, video and multimedia. Students say what each medium does well, what it does poorly, and which fits a given purpose and audience, with evidence.
What counts as a medium in RI.8.7?
Any form a presentation can take. The standard's examples are print text (books, letters, newspapers), digital text (web pages and e-books, which can have links and updates), video, and multimedia (combinations of text, pictures, sound, maps and clickable features). Podcasts, museum exhibits and infographics count too.
How is RI.8.7 different from RI.7.7?
RI.7.7 compares a text with an audio, video or multimedia version of that same text and analyzes how each medium portrays the subject. RI.8.7 goes a step further: students evaluate, judging the strengths and weaknesses of each medium for presenting a topic, and deciding which is better for a purpose.
Do students need to watch videos to practice RI.8.7?
No. Videos and websites can be described in words, as storyboards and plans, which lets every class practice without screens or internet access and lets students cite the description exactly. Teachers who have good videos on a topic can of course use them as well.
What makes an answer an evaluation and not just a list?
An evaluation weighs. A list says "the video has music and a map." An evaluation says which of those features helps or hurts, for whom and for what purpose, and why the advantages do or do not outweigh the disadvantages. The strongest answers admit a weakness in the medium they choose.
Is video always better for a visual topic?
No. Video is strong at showing motion, size and place, but some visual topics are better served by a labeled diagram or a careful written description that a reader can study closely. Which medium is better depends on the purpose and the audience, so students should name both before they judge.
What is the difference between print text and digital text?
They use the same kind of words, but they reach readers differently. Print needs no power, screen or connection, and it is easy to mark up by hand. Digital text lives on a screen, which brings its own tools and its own problems. Students should list the specific features a page offers and ask whether each one helps or hurts for the purpose.
How is RI.8.7 assessed?
Usually with questions that ask what one medium shows better than another, or which medium best suits a purpose, followed by a short written explanation. Some tests describe a video or website in words, as this lesson does. A full-credit answer names a specific advantage and disadvantage and supports them with details.
How does RI.8.7 connect to writing and speaking?
Directly. When students give presentations, SL.8.5 asks them to add multimedia and visual displays that clarify information, so knowing each medium's strengths helps them choose well. In research writing, W.8.8 asks them to gather information from print and digital sources and judge each one, which uses the same habits of evaluation.
How can parents help with RI.8.7 at home?
Ask about something your child learned from a video or website: "What did the video show that a book could not? What did it leave out? Where would you go to check it?" Comparing a news article with a news video on the same story is a good everyday exercise.
