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.

Lesson Plan

55-65 min

Overview

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

Lesson Procedure

55-65 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Warm-Up Prompt

    "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.

  2. 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
    QuestionWhat to look for
    AccuracyDoes it keep the facts straight and mark what is guessed or acted out?
    DetailDoes it give exact words, numbers and small details, or only the big picture?
    ShowingCan it show size, place, motion and sound, or must the audience imagine them?
    ControlCan the audience slow down, go back and skim, or does the medium set the pace?
    AccessWhat does the audience need: a screen, an internet connection, sound, good eyesight or hearing?
    FocusDoes 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.

    He 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.

    [...]

    He 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.

    [...]

    They 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.

    Shot 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..."

    Shot 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."

    Shot 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."

    Shot 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."

    Shot 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."

    Shot 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."

    Below 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 ___."

  3. 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).

    Opening 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.

    The 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."

    Listen. 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.

    Look 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."

    Map 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.

    Check 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:

    1. 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.
    2. 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.
    3. 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.
  4. 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.

    Updated March 3, 2026. 4-minute read. Text size: A / A+ / A++. Button: "Listen to this article" (read aloud by a computer voice).

    In 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.

    Pliny 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.

    The 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.)

    Related articles: "Ten Volcanoes You Can Visit" (link). "The Five Best Disaster Movies" (link). Advertisement: "Book your Naples tour today!"

    Comments (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)."

  5. 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).

    The 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."

    We 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.

    It 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.

    [...]

    At 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.

    Pliny the Younger, translated by William Melmoth, revised by F. C. T. Bosanquet, Passage 5: Letter LXVI, To Cornelius Tacitus, on Pliny's own escape (one sentence left out and marked [...]) (1746; this edition 1909). Public domain (published 1909). Source text.

    Length: 14 minutes. Format: audio only, free on podcast apps. Listeners can pause, skip back 15 seconds, or play the episode at up to twice the normal speed.

    0:00-1:30. Theme music, then the host introduces herself and the story: "Today, a teenager, his mother, and a cloud that swallowed the sun."

    1:30-7:00. An actor reads Pliny's letter about his escape, cut down to about four minutes. Behind the voice, the sound designer adds a crowd: footsteps, a baby crying, people calling out names. As the darkness falls, the sounds get closer and the music drops away until only the voices are left.

    7:00-7:45. A break for an advertisement for a sleep app.

    7:45-12:30. The host explains that ash from Vesuvius fell on Misenum but did not bury it, and that Pliny and his mother survived. She adds her own guess: "I think Pliny felt guilty for years that he stayed calm while others panicked."

    12:30-14:00. Credits and a question for listeners to answer by recorded message.

    A written transcript of the episode is posted on the show's website one week after the audio.

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

  1. A family on a camping trip with no phone signal wants to read about the stars they can see.
  2. A soccer coach wants to teach a new passing drill to players who learn by watching.
  3. A science class needs to look up many related facts about sharks quickly, jumping from one question to the next.
  4. A museum visitor wants to explore a shipwreck at their own pace, choosing what to look at.
  5. A student must quote a president's exact words in a history essay.
  6. A viewer who is deaf wants to learn how bees build a hive.
  7. A town wants every household, including people without computers, to know the new recycling rules.
  8. 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

  1. Pompeii lies about 10 kilometers southeast of Vesuvius and was buried under several meters of ash and pumice.
  2. Vesuvius last erupted in 1944, during World War II.
  3. Excavations at Pompeii began in 1748 and still go on today.
  4. 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

  1. "Help a visitor to Naples understand why the town is still in danger from Vesuvius."
  2. "Give a history class the exact words of someone who lived through a disaster."
  3. "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.

Diagram 1: One Topic, Two Mediums, a Sample Rating

One topic, two mediums: a sample rating Passage 1 print letter Passage 2 online video Gives the exact words of the eyewitness Shows size, distance and place at a glance Lets the audience set its own pace Marks what is known and what is guessed Makes the scene vivid with sight and sound Works without a screen or an internet connection Filled circles: how well the medium does this for the Vesuvius topic (3 = very well). A sample judgment, not an answer key: students may rate differently if they give reasons.
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

Medium evaluation card Medium print, digital text, video, or multimedia? Topic or idea what is being presented? Purpose and audience who needs it, and for what? Advantages What does this medium do well for this topic? Quote or name it. Disadvantages What does it do poorly, leave out or make harder? Name it. Verdict For this purpose and audience, the medium is strong / mixed / weak, because its biggest advantage ____ outweighs (or does not outweigh) ____.
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.

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)

  1. 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.
  2. 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)

  1. 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.
  2. 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)

  1. 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.
  2. 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.

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.
