RI.8.8: Delineating and Evaluating an Argument

In plain English: RI.8.8 is the Common Core grade 8 ELA standard that asks students to delineate and evaluate the argument and specific claims in a text. Students lay out the claim, the reasons and the evidence, judge whether the reasoning is sound and the evidence relevant and sufficient, and recognize when irrelevant evidence is introduced. It builds on RI.7.8.

Delineate and evaluate the argument and specific claims in a text, assessing whether the reasoning is sound and the evidence is relevant and sufficient; recognize when irrelevant evidence is introduced.

Lesson Plan

55-65 min

Overview

Students learn to delineate an argument, which means laying out its parts: the claim (what the writer wants readers to believe or do), the reasons that support it and the evidence behind each reason. Then they evaluate it with three tests from the standard. Is the evidence relevant, meaning it actually supports the reason it is attached to? Is it sufficient, meaning there is enough of it, of the right kind? Is the reasoning sound, meaning the reasons really lead to the claim? Grade 8 adds one more job: recognizing when a writer introduces irrelevant evidence, facts that may be true but support nothing in the argument.

The public-domain texts come from a 1913 Ohio Arbor Day and Bird Day manual, written for teachers when the bird-protection movement was new. The teacher models the tests with Eugene Swope's short appeal for bird clubs in schools (Passage 1). Pairs map a student editorial invented for this page (Passage 2), and students work alone on part of William Dutcher's leaflet on the cardinal (Passage 3) for the quiz. The homework uses an invented letter to the editor about turning off streetlights for migrating birds (Passage 4). All four passages are printed in the lesson plan.

Learning Objectives

By the end of this lesson, students will be able to:

  • Delineate an argument: state its claim, list its reasons and match each piece of evidence to the reason it supports
  • Evaluate whether evidence is relevant and sufficient to support a specific claim, citing the text
  • Assess whether a writer's reasoning is sound, and explain where a chain of reasoning breaks
  • Recognize when irrelevant evidence is introduced and explain why it does not support the claim

Prior Knowledge Required

Students should already be comfortable with:

  • Tracing and evaluating an argument, assessing whether the reasoning is sound and the evidence relevant and sufficient RI.7.8
  • Distinguishing claims that are supported by reasons and evidence from claims that are not RI.6.8
  • Citing textual evidence with a passage and paragraph number RI.8.1
  • Telling a fact (something that can be checked) from an opinion (a belief or judgment)

Lesson Procedure

55-65 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Warm-Up Prompt

    "A friend says, 'We should get a class pet. My cousin's class has a hamster, hamsters are cute, and I read that pets teach responsibility.' Which of your friend's three reasons would convince a principal? Which would not, and why?"

    Take several answers. Students usually see that "hamsters are cute" is an opinion, that the cousin's class shows only that one other class has a pet, and that "pets teach responsibility" is the closest to a real reason but needs support ("I read that" where?). Name what they just did: they separated the claim (we should get a class pet) from the reasons, and they judged each one. RI.8.8 asks students to do this with a whole text, and to notice when a writer slips in something that sounds like support but is not.

  2. Direct Instruction15 minutes

    Teach the terms and leave them on the board:

    • Argument: a claim supported by reasons and evidence. Delineate: lay out the parts of the argument clearly, like drawing the lines of a map.
    • Claim: the main point the writer wants readers to believe or act on. A long text also makes smaller specific claims along the way.
    • Reason: a statement that explains why the claim should be accepted.
    • Evidence: facts, numbers, examples, observations or expert statements that back up a reason.
    • Relevant evidence actually supports the reason it is attached to. Irrelevant evidence may be true and interesting, but it supports nothing in the argument.
    • Sufficient evidence is enough, and of the right kind, to support the reason: one friend's opinion is rarely sufficient for a claim about a whole school.
    • Sound reasoning: the reasons really lead to the claim. Reasoning is unsound when a step does not follow, for example when one example is stretched into a rule for everyone.

    Show Diagram 1 and walk through its small example.

    Introduce the text. In the early 1900s, many kinds of American birds had been hunted or trapped until few were left, some for feathers on hats and some to be sold as pets. Groups called Audubon societies, named for the bird artist John James Audubon, worked to protect them, and they started Junior Audubon Classes, bird-study clubs for schoolchildren. In April 1913, Ohio's State Commissioner of Common Schools issued a manual for Arbor Day and Bird Day, and state law required it to be passed out to teachers. Passage 1 is its short article by Eugene Swope, who worked for the Audubon society in Ohio, written to school leaders. Words to know: Superintendent (the head of a school district), Commissioner (here, the head of Ohio's schools), Supervisors of Agriculture (officials in charge of teaching farming), elementary agriculture (beginning farming lessons), remnant (the small part that is left), gratifying (pleasing), develope (an old spelling of develop), originality (new ideas of one's own), composition work (writing assignments), correspond (write letters) and gratis (free). Read Passage 1 aloud.

    The national movement for the study and protection of our wild birds is as well understood and supported by the teachers of Ohio as of any other State. The number of Junior Audubon Classes formed in the schools of Ohio last year was second only to New Jersey. That little State took the lead. Ohio ought to take the lead this year. With our Commissioner F. W. Miller giving his approval and encouragement, and our Supervisors of Agriculture recommending bird study as a necessary feature of elementary agriculture, Ohio ought to be able to report a large number of Bird Classes by the middle of May.

    It is a rare thing to find a Superintendent or principal actually unfriendly toward bird study, but a very large percent hesitate to admit it into their schools because it is new and untried.

    The claims of bird study upon Superintendents and principals is one that cannot much longer be overlooked. The National desire to know the wild birds and to save the remnant now left, is yearly becoming stronger. An ever-increasing number of homes are becoming active centers and parents are looking to the public schools for help, and children everywhere are eager for bird study.

    There is no risk in introducing Junior Audubon Classes in a school. Some of our country's foremost educators have tried it with gratifying results, for they find that there is no better subject to develope the power of attention in children, there is no better subject to train children's memories, there is no better subject to awake originality of thought in young minds, and it is unquestionably the supreme subject for composition work. Any teacher who cares to give bird study a trial may correspond with me and receive gratis, the help now offered by the Ohio Audubon Society.

    Eugene Swope, Audubon Field Agent for Ohio, Passage 1: "Bird-Study in Ohio Public Schools" (complete) (1913). Public domain (published 1913). Source text.
    • Delineate: find the claim and the reasons

      Swope writes to superintendents and principals that "The claims of bird study upon Superintendents and principals is one that cannot much longer be overlooked" (paragraph 3) and ends by inviting "Any teacher who cares to give bird study a trial" to write to him (paragraph 4). What is his claim, and what reasons does he give?

      Result: Claim: schools should start Junior Audubon Classes now. Reason 1 (paragraph 3): the public wants it, since the national desire to know and save birds is growing, parents look to the schools and children are eager. Reason 2 (paragraph 4): it is safe, "There is no risk." Reason 3 (paragraph 4): bird study builds attention, memory, original thinking and writing. Paragraph 2 sets up the problem: many leaders "hesitate to admit it into their schools because it is new and untried."

    • Sufficient? Vague evidence

      To support "There is no risk," Swope writes: "Some of our country's foremost educators have tried it with gratifying results" (paragraph 4). Is this evidence sufficient?

      Result: No. The evidence is relevant, since results from schools that tried bird study do bear on whether it is risky. But it is not sufficient: the "foremost educators" are not named, we are not told how many tried it or where, and "gratifying results" does not say what the results were. A principal could not check any of it. One named school with a description of what happened would be stronger.

    • Relevant? Evidence that supports nothing

      Swope opens with a fact: "The number of Junior Audubon Classes formed in the schools of Ohio last year was second only to New Jersey. That little State took the lead. Ohio ought to take the lead this year." Does this evidence support the claim that bird study is good for students?

      Result: No. Ohio's ranking against New Jersey says how many classes were formed, not whether they helped anyone. It appeals to state pride ("Ohio ought to take the lead"), a reason to compete, not a reason to believe bird study works. It is relevant only to the smaller claim that many Ohio schools already have classes. For the main claim, it is irrelevant evidence.

    • Sound? Does the reasoning follow?

      Swope says leaders hesitate "because it is new and untried," and answers in paragraph 4: "There is no risk in introducing Junior Audubon Classes in a school." Is this reasoning sound?

      Result: Only partly. Swope answers the right worry, and that is a strength. But the answer is an assertion: "There is no risk" is stated as a fact, and the only support is the vague report about "foremost educators." A new program can carry costs, such as time taken from other subjects, that Swope never discusses. The step from "some educators liked it" to "no risk in a school" does not follow.

    Map, then test. Model the routine with the examples: (1) write the claim in your own words; (2) list the reasons and draw each piece of evidence under the reason it supports; (3) test each link: relevant? sufficient? sound?; (4) put anything that supports no reason in the "irrelevant" box. Give students a frame: "The writer claims ___. The reason ___ is supported by ___, which is relevant / irrelevant because ___ and sufficient / insufficient because ___."

  3. Guided Practice15 minutes

    Read Passage 2 aloud: an editorial for a school newspaper by an eighth grader, invented for this page. An editorial is an article that argues for an opinion. Students copy Diagram 2, the argument map, and fill it in with a partner, highlighting reasons in one color and evidence in the other. Then pairs answer the three questions below. Teacher notes:

    Our school should add a twenty-minute silent reading period every day, right after lunch. Students would read any book they choose, and teachers would read too. I believe this one change would make us better readers and calmer students.

    First, students want this. Last month I surveyed my English class, and 20 of the 28 students said they would read more if they had time for it at school. That is more than two thirds of the class.

    Second, reading makes you smarter. The students with the best grades in my class are all big readers. If everyone read for twenty minutes a day, everyone's grades would go up.

    Third, a reading period would calm the school down after lunch. Everyone knows the hallways are loud and wild at 12:30. When I read before math class, I always feel more focused. Everyone I asked at my lunch table agreed with me, too.

    Reading has a long history. People have been writing books for thousands of years, and my favorite author writes every single morning and has published fourteen novels.

    Some teachers say they cannot give up twenty minutes of class time. But twenty minutes is nothing. Over a 180-day school year, it adds up to only 60 hours, and we waste more time than that waiting for the bell.

    The school board meets on March 12. Come and tell them: give us twenty minutes.

    Maya Torres, Grade 8

    Written for this page, Passage 2: A student editorial, "Give Us Twenty Minutes" (an invented school newspaper article written for this page; the student and the survey are invented). Original passage written for this page.
    1. Map it. What is the claim, and what are the three reasons? Teacher note: claim, "Our school should add a twenty-minute silent reading period every day, right after lunch" (paragraph 1). The reasons are signaled by "First," "Second" and "Third": students want it (paragraph 2), reading makes you smarter (paragraph 3), and it would calm the school after lunch (paragraph 4).
    2. Test the survey. Maya writes that "20 of the 28 students said they would read more if they had time for it at school." Which reason does this support, and is it enough? Teacher note: it is relevant to reason 1, that students want a reading period, and the arithmetic is right (20 of 28 is about 71 percent, "more than two thirds"). It is not sufficient for the whole school: it is one English class, the author's own, and "would read more" is not the same as "want the school day changed." It says nothing about reasons 2 and 3.
    3. Find the irrelevant evidence. Which paragraph supports none of the reasons? Teacher note: paragraph 5. That people "have been writing books for thousands of years" and that Maya's favorite author "has published fourteen novels" may be true, but neither fact shows that a reading period would help students at this school. It belongs in the "irrelevant evidence" box of the map.
  4. Independent Practice15 minutes

    Students read Passage 3 on their own and fill in a fresh argument map before they answer the quiz. It comes from the same 1913 manual: a leaflet on the cardinal by William Dutcher, the president of the National Association of Audubon Societies. In Dutcher's time, wild cardinals were often trapped and sold as cage birds. Words to know: aviculturist (a person who raises birds in captivity), the cage bird fancy (the hobby of keeping birds in cages), bred (raised to have young), traffic (here, buying and selling), the Model Law (a sample bird-protection law that many states passed), unavailing (useless), cynic (someone who trusts no one), morose and crusty (gloomy and grumpy), antithesis (exact opposite), sylvan shades (shady woods), esthetic (having to do with beauty), husbandman (farmer), larvae (young insects) and rose-bugs (beetles that feed on roses). The quiz uses Passages 1-3.

    Dr. Russ, the great German aviculturist, says, "Beloved in its home by both Americans and Germans, it is protected and caught only for the cage bird fancy. Had been bred in Holland a century and a half ago and later in England." It is true that until recently large numbers of Cardinals were caught or taken from the nest while young, for shipment to foreign countries by bird dealers. Owing to the efforts of the National Association, this traffic is a thing of the past. The Model Law, which is in force in all the States where the Cardinal is found, prohibits all traffic in these birds and forbids their being shipped from the State.

    The Cardinal is too beautiful and valuable a bird to be confined within the narrow limits of a cage, where its splendid spirit is soon broken by its unavailing attempts to escape. Mrs. Olive Thorne Miller, in one of her charming pictures of bird life, says of a captive Cardinal, that, "He is a cynic, morose and crusty." Such a character cannot be attributed to the Cardinal when it is at liberty. Its wild, free song, its restless activity and its boldness are the antithesis of a depressed cage captive. Even when it receives the best care from its human jailer it is still a prisoner confined in a space so small that it never has an opportunity to stretch its wings in flight, nor can it ever bathe in the bright sunshine or view the blue skies above it. The whispering of the winds through the sylvan shades is lost to the captive forever. Is it strange that the nature of this wild free spirit changes?

    The writer has seen many hundreds of these beautiful birds in cages ready to be shipped, each one doomed to a short existence, a prisoner and an exile. Fortunately, this condition is now changed; and, had the National Association accomplished no other good, the stopping of the cage-bird traffic would be a sufficient reason for its organization.

    [...]

    In addition to its great esthetic value of song and plumage, the Cardinal has another important character which should endear it to the husbandman. Its food is various, consisting of wild fruits such as grapes, berries, mulberries, cedar berries, seeds of grasses and of many species of weeds, also large numbers of adult beetles, grasshoppers, crickets, flies, ants and their larvae; it is especially fond of rose-bugs. The Cardinal is from every point of view a bird of great interest and value, and any person who makes its intimate acquaintance will form a life-long friendship.

    William Dutcher, President of the National Association of Audubon Societies, Passage 3: "The Cardinal," the paragraphs on keeping cardinals in cages and on their food (one cut marked [...]) (1913). Public domain (published 1913). Source text.
  5. Closure5-10 minutes

    Exit ticket: (1) In your own words, explain the difference between evidence that is irrelevant and evidence that is insufficient. (2) Write one sentence of irrelevant evidence that someone might add to an argument for a longer lunch period, and explain why it is irrelevant.

    Teacher note on the 1913 texts. Passages 1 and 3 are printed exactly as they appear in the manual, including Swope's spelling "develope" and his sentence "The claims of bird study ... is one," where today we would write "are." The texts reflect their time: Dutcher describes a cardinal couple's "domestic felicity" elsewhere in the leaflet, and both writers assume readers already love birds. The history is real. Audubon societies were among the groups campaigning in these years against the trade in wild birds, and today cardinals, like nearly all native songbirds in the United States, are protected by the Migratory Bird Treaty Act of 1918, so catching or keeping one as a pet is illegal. Olive Thorne Miller, quoted in Passage 3, was a popular American nature writer, and Dr. Russ was Karl Russ, a German writer on cage birds. Passages 2 and 4 are invented: Maya Torres, R. Delgado, the Maple Creek Bird Club and their numbers do not exist. The facts that Passage 4 reports about bird migration and "Lights Out" programs in Chicago and New York are real.

    For homework: students read Passage 4, an invented letter to the editor of a town newspaper, printed below. Words to know: migrate (travel with the seasons), artificial light (light made by people, not by the sun or moon), peak weeks (the weeks when the most birds are traveling), stunned (knocked senseless) and town council (the group that makes the town's rules).

    To the Editor: Every spring and fall, huge numbers of birds fly over our state at night. Many songbirds migrate in the dark, and bright artificial light can pull them off course. Cities such as Chicago and New York already run "Lights Out" programs that ask building owners to turn off unneeded lights at night during migration. Our town should do its part by turning off half of its 1,200 streetlights from midnight to 5 a.m. during the peak weeks of the spring and fall migrations, about sixteen weeks in all.

    The need is clear. Last fall, volunteers from the Maple Creek Bird Club walked around the glass office tower on Elm Street every morning and found 46 dead or stunned birds below its windows. Those birds did not have to die.

    The plan would also save money. The town spends about $90,000 a year to power its streetlights. If we turn off half the lights, we will save half the birds and half the money.

    Some people worry that darker streets would be less safe. But there has been no streetlight on my corner for two years, and nothing bad has happened.

    My grandfather used to say that the stars were brighter when he was a boy, before all these lights. He loved birds, too, and he fed them every winter until he was ninety.

    Please ask the town council to vote yes on Lights Out.

    R. Delgado, Maple Creek

Differentiation Strategies

For Struggling Students

  • Give a partly filled argument map for Passage 2 with the claim written in and the three reason boxes labeled "First," "Second" and "Third"
  • Provide a card with the three test questions (relevant? sufficient? sound?) and a yes or no box for each piece of evidence
  • Read Passage 3 in two parts, paragraphs 1-2 and paragraphs 3-4, and map each part before combining them

For Advanced Students

  • Ask them to rewrite paragraph 4 of Passage 1 so that Swope's "There is no risk" is supported by relevant and sufficient evidence, inventing only what is clearly labeled as invented
  • Have them find the one reason in Passage 3 that Dutcher supports best, and argue in a short paragraph why it is the strongest
  • Ask them to compare the argument in Passage 1 with the argument in Passage 3 and decide which writer would convince a skeptical school board, and why

Assessment Guidance

What to Look For

Check that students state the claim in their own words, match each piece of evidence to the reason it supports, and give a reason for every judgment: why evidence is or is not relevant, why it is or is not sufficient, and where a step in the reasoning does or does not follow. Strong answers quote the exact words and suggest what better evidence would look like. A common weak answer calls evidence "bad" because the student disagrees with the claim; ask "Does this support the reason, even if you disagree?" and "How much evidence would be enough?"

Classroom Activities

3 Activities

1

Evidence Sort

15 minPairs

Pairs get one claim and eight evidence strips, all written for this activity; the school, the survey and the numbers are invented. They sort the strips into three piles: relevant and sufficient, relevant but not sufficient, and irrelevant.

The Claim and the Eight Strips

Claim: "Lakeview Middle School should add a second, ten-minute recess in the afternoon."

  1. "A survey of all 450 Lakeview students found that 372 want a second recess."
  2. "My best friend said she would like more recess."
  3. "Lakeview's mascot is the Lakeview Loon."
  4. "The gym teacher kept a log for a month: on days with an extra break, her afternoon classes had half as many students sent to the office."
  5. "Recess was popular when my parents went to school."
  6. "Two nearby middle schools added afternoon recess last year, and both principals report calmer afternoons, but neither school kept any records."
  7. "The playground was repainted in bright colors last summer."
  8. "A student at another school said recess helps her focus."

Procedure

  • Pairs sort the strips and write one sentence for each explaining their choice (8 minutes)
  • Pairs join another pair and settle one strip they sorted differently (5 minutes)
  • Answer key for the teacher: relevant and sufficient, 1 and 4 (a whole-school survey and a month of records; strip 4 comes from only one teacher's classes, so some pairs may call it not sufficient, which is fine with a reason); relevant but not sufficient, 2, 6 and 8 (one friend, reports with no records, one student at another school); irrelevant, 3, 5 and 7 (the mascot, the past and the paint say nothing about whether a second recess would help)

Discussion Questions

  • Strip 7 is about the playground. Could a writer make it relevant? What reason would it need to be attached to?
  • What would make strip 6 sufficient?

Modification

For students who need support, sort strips 1, 2 and 3 together first, one from each pile, before pairs sort the rest.

2

Build a Broken Argument

15 minGroups of 3-4

Groups write a short argument of five or six sentences on a school topic and hide three flaws in it on purpose. Another group has to find them.

Topics

  • Students should be allowed to listen to music during independent work.
  • The school should hold one field trip every month.
  • Every student should learn to cook one meal before high school.

Procedure

  • Each group writes a claim, two reasons and evidence, and hides exactly three flaws: one piece of irrelevant evidence, one reason with insufficient evidence, and one step of reasoning that does not follow (8 minutes)
  • Groups trade arguments on chart paper. The receiving group maps the argument with Diagram 2 and labels each flaw (5 minutes)
  • Writers confirm or correct the labels (2 minutes)

Discussion Questions

  • Which kind of flaw was hardest to hide, and which was hardest to find?
  • How would you fix the insufficient evidence without changing the claim?
3

Argument Court

10 minWhole class

The teacher reads short arguments aloud. Every student is a judge with a green card (the reasoning holds) and a red card (a flaw), and must explain any red card.

The Three Cases

  1. "Our class should visit the science museum. The museum's new exhibit is about the planets, and we are studying the planets this month. The trip costs $12 per student, which the parent group has offered to pay."
  2. "We should ban homework on weekends. My cousin never has weekend homework, and he is very happy. Also, weekends were invented to rest."
  3. "Everyone should drink more water. Water is good for you, so drinking more of it must always be better."

Procedure

  • After each case, students raise a card on the count of three
  • Call on two red cards and one green card to explain
  • Answer key for the teacher: case 1 holds up (green): the evidence is relevant and there is enough of it for a class trip; case 2 has insufficient evidence (one cousin) and irrelevant evidence (why weekends exist); case 3 is unsound reasoning: "good for you" does not mean "more is always better"

Variation

For a harder version, students must also say what one piece of evidence would fix each red-card case.

Homework Assignment

~30 min

RI.8.8 Homework: Lights Out for the Birds

Directions: Read Passage 4 at the end of the lesson plan (in Closure). Cite it by paragraph, for example (Passage 4, paragraph 2). For every judgment, quote the words you are judging and give a reason. Answer Problems 1-5 in 3-5 sentences each; you may draw a map for Problem 1.

Part 1: Delineate the Argument (Problems 1-2)

  1. Delineate the argument in Passage 4. State the claim in your own words, list the reasons, and write the evidence the writer gives under each reason. You may use the argument map from Diagram 2.
  2. Which reason in Passage 4 is supported only by the writer's own experience? Quote the evidence and explain whether it is sufficient to answer the worry the writer raises.

Part 2: Evaluate the Evidence (Problems 3-4)

  1. In paragraph 2, volunteers "found 46 dead or stunned birds below its windows" at "the glass office tower on Elm Street." Is this evidence relevant to a plan to turn off streetlights? Explain what it does and does not show, and suggest one piece of evidence that would be more relevant.
  2. Find the paragraph in Passage 4 that introduces irrelevant evidence. Quote it, and explain why it does not support any reason, even though it may be true and may make readers feel something.

Part 3: Test the Reasoning (Problems 5-6)

  1. The writer says, "If we turn off half the lights, we will save half the birds and half the money." Using the plan the writer describes in paragraph 1 (which lights, which hours, how many weeks), explain why this reasoning is not sound, for the birds and for the money.
  2. Write a paragraph of 6-8 sentences evaluating the whole argument in Passage 4. Is the claim reasonable? Which parts of the argument are strongest and weakest? Judge the relevance and sufficiency of at least two pieces of evidence and the soundness of at least one step of reasoning, and end with one change that would make the letter more convincing.

Frequently Asked Questions

10 Questions

What does RI.8.8 mean?

It means eighth graders lay out an argument's parts and judge how well they hold up. The standard asks students to "delineate and evaluate the argument and specific claims in a text," to assess "whether the reasoning is sound and the evidence is relevant and sufficient," and to "recognize when irrelevant evidence is introduced."

What does "delineate" mean in RI.8.8?

It means to lay out clearly, the way a map draws lines. Students state the claim, list the reasons and show which evidence supports which reason. A diagram or outline is a good way to delineate an argument before judging it.

How is RI.8.8 different from RI.7.8?

The two are close. RI.7.8 asks students to trace and evaluate an argument and assess its reasoning and evidence. RI.8.8 uses "delineate" instead of "trace," asking for a clearer layout of every part, and adds a new job: recognizing when irrelevant evidence is introduced.

What is the difference between relevant and sufficient evidence?

They are two separate tests. Relevant evidence is on topic: it actually supports the reason it is attached to. Sufficient evidence is enough: there is enough of it, of the right kind, to be convincing. Evidence can be relevant but not sufficient, such as a single news story offered as proof of something true across a whole country.

What is irrelevant evidence?

Irrelevant evidence is information offered as support that does not support the claim or any reason. It is often true and may stir feelings, which is why it can slip past readers. A good test is to ask, "If this were false, would the argument be any weaker?" If not, it is irrelevant.

What makes reasoning sound or unsound?

Reasoning is sound when each step really leads to the next. It is unsound when a step does not follow, for example when a writer turns a single example into a rule for everyone, or skips a step that the reader is simply asked to accept.

Does a student have to disagree with an argument to find flaws in it?

No. Evaluating an argument is not the same as rejecting it. A reader can agree with a claim and still point out that its evidence is thin, and a claim can be true even when a particular argument for it is weak. This lesson's texts argue for protecting birds, a goal many readers share.

How is RI.8.8 assessed on tests?

Usually with a passage that makes an argument and questions that ask which sentence states the claim, which evidence best supports a reason, or which sentence is irrelevant. Some questions come in pairs, with a second part asking which quotation supports the first answer. Short written answers ask students to judge a piece of evidence and explain why.

Why use old texts from 1913 to teach argument?

Short historical arguments are free to print in full, and they show that the same tests apply in any era. Because readers today know how the bird-protection story turned out, they can focus on how well each writer argued rather than on whether they agree.

How does RI.8.8 connect to speaking and writing?

SL.8.3 asks students to evaluate a speaker's argument with the same tests, including irrelevant evidence. In their own argument writing, students use the tests in reverse: every piece of evidence should support a reason, there should be enough of it, and every step should follow.
