RH.9-10.8: Assessing How Well Reasoning and Evidence Support an Author's Claims

In plain English: RH.9-10.8 is the Common Core literacy standard for history that asks students in grades 9-10 to assess the extent to which the reasoning and evidence in a text support the author's claims. The key idea is that support comes in degrees: some claims rest on specific, relevant evidence and sound reasoning, others on assertion alone. It is usually taught in World History or U.S. History.

Assess the extent to which the reasoning and evidence in a text support the author's claims.

Lesson Plan

60-75 min

Overview

Students assess the extent to which the reasoning and evidence in a historical argument support the author's claims. A claim is a statement the author wants readers to accept; evidence is what the author offers as fact to back it (an event, a document, a number, a witness); reasoning is the step that explains why the evidence, or a principle, leads to the claim. "The extent" matters: students do not simply call an argument strong or weak. They rate each claim as well supported, partly supported or asserted (stated with no real support in the text), and they say why, using three tests for evidence (Is it relevant? Is it specific enough to check? Is there enough of it?) and one test for reasoning (What must be true for this step to work, and is it?).

The text is Woodrow Wilson's war message to Congress of April 2, 1917, read with two earlier messages from the same winter: the message of February 3, which quotes the German notes that Wilson treats as his evidence, and the message of February 26. Wilson's argument mixes claims of very different strength: some rest on documents he quotes, some on reasoning a reader can test, and some on assertion alone. Students judge the argument by the support inside the text, not by whether they agree with the decision for war.

Learning Objectives

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

  • Separate an author's claims from the evidence and reasoning offered for them, citing paragraph numbers
  • Test evidence for relevance, specificity and sufficiency, and explain what evidence a claim would need
  • State the unstated assumption that links evidence to a claim and judge whether the text gives reason to accept it
  • Rate how far each claim is supported (well supported, partly supported, asserted) and defend the rating in writing

Prior Knowledge Required

Students should already be comfortable with:

  • Distinguishing fact, opinion and reasoned judgment in a text RH.6-8.8
  • Citing specific textual evidence from primary sources, attending to the date and origin of the information RH.9-10.1
  • Basic background: World War I began in Europe in 1914; the United States stayed neutral until April 1917; German submarines (U-boats) attacked shipping bound for Britain and France

Lesson Procedure

60-75 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Project the prompt and give students three minutes to write.

    Warm-Up Prompt

    "A city council member argues: 'We must close Elm Street to cars. Elm Street is the most dangerous street in town. Last month a cyclist was hit there, and residents tell me they are afraid to cross.' Which part of her argument is well supported, which is only partly supported, and which is simply asserted? What one piece of evidence would you ask her for?"

    Collect three answers. Students usually see that one accident is real evidence but not enough to show that Elm Street is "the most dangerous street," which would need accident counts for other streets, and that residents' fear is relevant but vague. Name the skill: to assess the extent of support, test each claim separately and ask what the evidence actually shows.

  2. Direct Instruction20 minutes

    Part 1: The support test. Show the table. Students copy it onto a support chart with three columns: claim, support offered, rating.

    Testing the support for one claim
    PartQuestion to askSigns of weak support
    ClaimWhat exactly is asserted, and how strongly ("every," "never," "practically certain")?A sweeping word that the evidence cannot cover
    EvidenceIs it relevant to this claim? Is it specific enough to check (names, dates, numbers, documents)? Is there enough of it?Categories instead of cases; "it is known"; proof mentioned but not given
    ReasoningWhat must be true for the step from evidence to claim to work? Does the text give reason to accept that?A rule stated about all cases from one case; an unstated assumption the text never defends
    RatingWell supported, partly supported or asserted?A rating with no quotation behind it

    Part 2: The war message. Give the background in two sentences: on January 31, 1917, Germany announced that its submarines would sink ships in a zone around Britain, France and Italy without warning; on April 2, Wilson asked Congress to declare that Germany's actions amounted to war. Read T1 aloud, then T2. Students mark each claim with a C, each piece of evidence with an E and each reasoning step with an R. Diagram 1 shows where the texts fall in time.

    On the 3d of February last I officially laid before you the extraordinary announcement of the Imperial German Government that on and after the first day of February it was its purpose to put aside all restraints of law or of humanity and use its submarines to sink every vessel that sought to approach either the ports of Great Britain and Ireland or the western coasts of Europe or any of the ports controlled by the enemies of Germany within the Mediterranean. That had seemed to be the object of the German submarine warfare earlier in the war, but since April of last year the Imperial Government had somewhat restrained the commanders of its undersea craft in conformity with its promise then given to us that passenger-boats should not be sunk, and that due warning would be given to all other vessels which its submarines might seek to destroy when no resistance was offered or escape attempted, and care taken that their crews were given at least a fair chance to save their lives in their open boats.

    The precautions taken were meager and haphazard enough, as was proved in distressing instance after instance in the progress of the cruel and unmanly business, but a certain degree of restraint was observed.

    The new policy has swept every restriction aside. Vessels of every kind, whatever their flag, their character, their cargo, their destination, their errand, have been ruthlessly sent to the bottom without warning, and without thought of help or mercy for those on board, the vessels of friendly neutrals along with those of belligerents. Even hospital-ships and ships carrying relief to the sorely bereaved and stricken people of Belgium, though the latter were provided with safe conduct through the proscribed areas by the German Government itself and were distinguished by unmistakable marks of identity, have been sunk with the same reckless lack of compassion or of principle.

    I was for a little while unable to believe that such things would, in fact, be done by any Government that had hitherto subscribed to the humane practices of civilized nations. International law had its origin in the attempt to set up some law which would be respected and observed upon the seas, where no nation had right of dominion, and where lay the free highways of the world. By painful stage after stage has that law been built up with meager enough results, indeed, after all was accomplished that could be accomplished, but always with a clear view at least of what the heart and conscience of mankind demanded.

    This minimum of right the German Government has swept aside under the plea of retaliation and necessity, and because it had no weapons which it could use at sea except these, which it is impossible to employ as it is employing them without throwing to the winds all scruples of humanity or of respect for the understandings that were supposed to underlie the intercourse of the world.

    I am not now thinking of the loss of property involved, immense and serious as that is, but only of the wanton and wholesale destruction of the lives of non-combatants, men, women, and children engaged in pursuits which have always, even in the darkest periods of modern history, been deemed innocent and legitimate. Property can be paid for; the lives of peaceful and innocent people cannot be.

    Woodrow Wilson, Why We Are at War, War Message to Congress, April 2, 1917: the new submarine policy (six consecutive paragraphs) (1917). Public domain (published 1917). Source text.

    The present German warfare against commerce is a warfare against mankind. It is a war against all nations. American ships have been sunk, American lives taken, in ways which it has stirred us very deeply to learn of, but the ships and people of other neutral and friendly nations have been sunk and overwhelmed in the waters in the same way. There has been no discrimination. The challenge is to all mankind. Each nation must decide for itself how it will meet it. The choice we make for ourselves must be made with a moderation of counsel and a temperateness of judgment befitting our character and our motives as a nation. We must put excited feeling away.

    Our motive will not be revenge or the victorious assertion of the physical might of the nation, but only the vindication of right, of human right, of which we are only a single champion.

    When I addressed the Congress on the 26th of February last I thought that it would suffice to assert our neutral rights with arms, our right to use the seas against unlawful interference, our right to keep our people safe against unlawful violence. But armed neutrality, it now appears, is impracticable. Because submarines are in effect outlaws when used as the German submarines have been used against merchant shipping, it is impossible to defend ships against their attacks as the law of nations has assumed that merchantmen would defend themselves against privateers or cruisers, visible craft giving chase upon the open sea.

    It is common prudence in such circumstances, grim necessity, indeed, to endeavor to destroy them before they have shown their own intention. They must be dealt with upon sight, if dealt with at all.

    The German Government denies the right of neutrals to use arms at all within the areas of the sea which it has proscribed, even in the defense of rights which no modern publicist has ever before questioned their right to defend. The intimation is conveyed that the armed guards which we have placed on our merchant-ships will be treated as beyond the pale of law and subject to be dealt with as pirates would be.

    Armed neutrality is ineffectual enough at best; in such circumstances and in the face of such pretensions it is worse than ineffectual; it is likely to produce what it was meant to prevent; it is practically certain to draw us into the war without either the rights or the effectiveness of belligerents.

    There is one choice we cannot make, we are incapable of making: we will not choose the path of submission and suffer the most sacred rights of our nation and our people to be ignored or violated. The wrongs against which we now array ourselves are not common wrongs; they reach out to the very roots of human life.

    Woodrow Wilson, Why We Are at War, War Message to Congress, April 2, 1917: warfare against mankind and armed neutrality (seven consecutive paragraphs) (1917). Public domain (published 1917). Source text.
    • Evidence by category, not by case (T1 paragraph 3)

      Wilson claims that "Vessels of every kind, whatever their flag, their character, their cargo, their destination, their errand, have been ruthlessly sent to the bottom without warning," and adds that "Even hospital-ships and ships carrying relief" to Belgium "have been sunk."

      Result: The evidence is relevant, and naming hospital ships and relief ships makes the charge sharper, but the paragraph gives kinds of ships, not ships: no name, date or number. A reader of the text alone cannot check it. Rating: partly supported. The claim fits the policy Germany announced (T1 paragraph 1), which helps, but "every kind" is a sweeping word the paragraph does not prove.

    • Reasoning from a principle (T1 paragraph 6)

      Wilson sets property aside: "I am not now thinking of the loss of property involved," and gives his reason: "Property can be paid for; the lives of peaceful and innocent people cannot be."

      Result: This is reasoning, not evidence. It works if the reader accepts the assumption that loss of life is a different kind of wrong from loss of goods, one that money cannot settle. Most readers accept it, so the reasoning supports his claim that this is not an ordinary dispute over shipping. It does not, by itself, show how many non-combatants had died; that would still need evidence.

    • A chain of reasoning with one vague link (T2 paragraphs 3-6)

      Armed neutrality "is impracticable" because submarines are "in effect outlaws," so ships must deal with them "upon sight, if dealt with at all," while Germany treats armed guards as pirates: "The intimation is conveyed." Therefore armed neutrality is "practically certain to draw us into the war."

      Result: The chain is clear: a hidden attacker cannot be warned off, so a guard must fire first, and firing first is an act of war. Each step follows from the one before. The weak link is evidence: "The intimation is conveyed" does not say who conveyed it, when or how. Rating: well reasoned, partly supported by evidence (Diagram 2).

  3. Guided Practice15 minutes

    T3 comes from Wilson's message of February 3, 1917. It quotes the German note of May 4, 1916 (the pledge given after a German submarine torpedoed the channel steamer Sussex in March 1916) and the German memorandum of January 31, 1917. These are the documents behind Wilson's claim that Germany broke its word, so students can test that claim against the evidence Wilson himself supplies. In the part marked [...], the American note of May 8, 1916 said the United States could not "for a moment entertain" any suggestion that German respect for American rights be made contingent on "the conduct of any other Government." Work through the two examples with the class, then have pairs rate paragraph 11 on their support chart.

    In reply to this declaration the German Government gave this Government the following assurances:

    The German Government is prepared to do its utmost to confine the operations of war for the rest of its duration to the fighting forces of the belligerents, thereby insuring the freedom of the seas, a principle upon which the German Government believes, now as before, to be in agreement with the Government of the United States.

    The German Government, guided by this idea, notifies the Government of the United States that the German naval forces have received the following orders:

    In accordance with the general principles of visit and search and destruction of merchant vessels recognized by international law, such vessels, both within and without the area declared as naval war zone, shall not be sunk without warning and without saving human lives, unless these ships attempt to escape or offer resistance.

    But neutrals cannot expect that Germany, forced to fight for her existence, shall, for the sake of neutral interest, restrict the use of an effective weapon if her enemy is permitted to continue to apply at will methods of warfare violating the rules of international law. Such a demand would be incompatible with the character of neutrality, and the German Government is convinced that the Government of the United States does not think of making such a demand, knowing that the Government of the United States has repeatedly declared that it is determined to restore the principle of the freedom of the seas from whatever quarter it has been violated.

    To this the Government of the United States replied on the 8th of May, accepting, of course, the assurances given, but adding:

    [...]

    To this note of the 8th of May the Imperial German Government made no reply.

    On the 31st of January, the Wednesday of the present week, the German Ambassador handed to the Secretary of State, along with a formal note, a memorandum which contains the following statement:

    The Imperial Government, therefore, does not doubt that the Government of the United States will understand the situation thus forced upon Germany by the Entente Allies' brutal methods of war and by their determination to destroy the Central Powers, and that the Government of the United States will further realize that the now openly disclosed intentions of the Entente Allies give back to Germany the freedom of action which she reserved in her note addressed to the Government of the United States on May 4, 1916.

    Under these circumstances Germany will meet the illegal measures of her enemies by forcibly preventing, after February 1, 1917, in a zone around Great Britain, France, Italy, and in the eastern Mediterranean all navigation, that of neutrals included, from and to France, etc. All ships met within the zone will be sunk.

    I think that you will agree with me that, in view of this declaration, which suddenly and without prior intimation of any kind deliberately withdraws the solemn assurance given in the Imperial Government's note of the 4th of May, 1916, this Government has no alternative consistent with the dignity and honor of the United States but to take the course which, in its note of the 18th of April, 1916, it announced that it would take in the event that the German Government did not declare and effect an abandonment of the methods of submarine warfare which it was then employing and to which it now purposes again to resort.

    Woodrow Wilson, Why We Are at War, Message to Congress, February 3, 1917: the German notes of May 4, 1916 and January 31, 1917 (eleven paragraphs; one cut marked [...]) (1917). Public domain (published 1917). Source text.
    • A claim the quoted evidence supports in part (T3 paragraphs 5, 9 and 11)

      Wilson says the January 31 memorandum "suddenly and without prior intimation of any kind deliberately withdraws the solemn assurance" of May 4, 1916. The May 4 note itself says that "neutrals cannot expect that Germany" will "restrict the use of an effective weapon if her enemy is permitted to continue" to break the rules of war, and the memorandum says Germany now takes back "the freedom of action which she reserved."

      Result: That Germany withdrew the assurance is well supported: paragraph 10 says "All ships met within the zone will be sunk." "Without prior intimation of any kind" is not supported by Wilson's own evidence: the 1916 note had already reserved a way out, and the memorandum points back to it. Wilson's stronger point is that the United States had rejected that condition in May 1916. Rating: the claim of withdrawal is well supported; "suddenly and without prior intimation" is asserted against the evidence.

    • The same test applied to the other side (T3 paragraphs 9-10)

      The German memorandum justifies the new policy by "the Entente Allies' brutal methods of war" and calls them "the illegal measures of her enemies."

      Result: The memorandum's reasoning is that one side's breaking of the law frees the other side to break it too. In the words quoted here, it names no Allied measure, so its claim about "brutal methods" is asserted in this text. Applying the same test to both governments keeps the assessment fair: the question is always what the text itself shows.

  4. Independent Practice15-20 minutes

    Students read T4 and T5, the second half of Wilson's argument, and fill in a support chart with at least four claims, one row each, before they take the quiz. Here Wilson moves from what Germany did at sea to why Germany did it and what kind of government Germany had, so remind students to watch for general rules stated about all governments of a kind, and to ask what evidence stands behind each one.

    We have no quarrel with the German people. We have no feeling toward them but one of sympathy and friendship. It was not upon their impulse that their Government acted in entering this war. It was not with their previous knowledge or approval.

    It was a war determined upon as wars used to be determined upon in the old, unhappy days when peoples were nowhere consulted by their rulers and wars were provoked and waged in the interest of dynasties or of little groups of ambitious men who were accustomed to use their fellow-men as pawns and tools.

    Self-governed nations do not fill their neighbor states with spies or set the course of intrigue to bring about some critical posture of affairs which will give them an opportunity to strike and make conquest. Such designs can be successfully worked only under cover and where no one has the right to ask questions.

    Cunningly contrived plans of deception or aggression, carried, it may be, from generation to generation, can be worked out and kept from the light only within the privacy of courts or behind the carefully guarded confidences of a narrow and privileged class. They are happily impossible where public opinion commands and insists upon full information concerning all the nation's affairs.

    A steadfast concert for peace can never be maintained except by a partnership of democratic nations. No autocratic Government could be trusted to keep faith within it or observe its covenants. It must be a league of honor, a partnership of opinion. Intrigue would eat its vitals away, the plottings of inner circles who could plan what they would and render account to no one would be a corruption seated at its very heart. Only free peoples can hold their purpose and their honor steady to a common end and prefer the interests of mankind to any narrow interest of their own.

    Does not every American feel that assurance has been added to our hope for the future peace of the world by the wonderful and heartening things that have been happening within the last few weeks in Russia?

    Russia was known by those who know it best to have been always in fact democratic at heart, in all the vital habits of her thought, in all the intimate relationships of her people that spoke their natural instinct, their habitual attitude toward life.

    Autocracy that crowned the summit of her political structure, long as it had stood and terrible as was the reality of its power, was not in fact Russian in origin, in character or purpose; and now it has been shaken and the great, generous Russian people have been added, in all their native majesty and might, to the forces that are fighting for freedom in the world, for justice and for peace. Here is a fit partner for a league of honor.

    Woodrow Wilson, Why We Are at War, War Message to Congress, April 2, 1917: the German people, autocracy and Russia (eight consecutive paragraphs) (1917). Public domain (published 1917). Source text.

    One of the things that have served to convince us that the Prussian autocracy was not and could never be our friend is that from the very outset of the present war it has filled our unsuspecting communities and even our offices of Government with spies and set criminal intrigues everywhere afoot against our national unity of council, our peace within and without, our industries and our commerce.

    Indeed, it is now evident that its spies were here even before the war began, and it is, unhappily, not a matter of conjecture, but a fact proved in our courts of justice, that the intrigues which have more than once come perilously near to disturbing the peace and dislocating the industries of the country have been carried on at the instigation, with the support, and even under the personal direction, of official agents of the Imperial German Government accredited to the Government of the United States.

    Even in checking these things and trying to extirpate them we have sought to put the most generous interpretation possible upon them because we knew that their source lay, not in any hostile feeling or purpose of the German people toward us (who were, no doubt, as ignorant of them as we ourselves were), but only in the selfish designs of a Government that did what it pleased and told its people nothing. But they have played their part in serving to convince us at last that that Government entertains no real friendship for us and means to act against our peace and security at its convenience. That it means to stir up enemies against us at our very doors the intercepted note to the German Minister at Mexico City is eloquent evidence.

    We are accepting this challenge of hostile purpose because we know that in such a Government, following such methods, we can never have a friend; and that in the presence of its organized power, always lying in wait to accomplish we know not what purpose, there can be no assured security for the democratic Governments of the world.

  5. Closure5-10 minutes

    Exit ticket: On an index card, finish the sentence twice, once for a claim you rated well supported and once for a claim you rated asserted: "The claim that ___ is ___ because the text ___." Collect the cards and sort them by claim to open the next lesson.

    Teacher note on the texts and their language: The passages are quoted exactly as printed in 1917, including dated phrases such as "unmanly business" (T1 paragraph 2; "unmanly" meant cowardly or dishonorable) and "running amuck" (T7 paragraph 4; today spelled "amok," a word English took from Malay, meaning to rush about attacking wildly, out of control). Tell students that the assessment asks how well the text supports its claims, not whether the United States was right to go to war. Some claims can be checked later against history, and students may raise them: for example, the new Russian government that Wilson praised was overthrown by the Bolsheviks in November 1917, and Russia made a separate peace with Germany in March 1918. Keep that for discussion; the rating of T4 depends on the support Wilson gave on April 2. T7 contains Wilson's promise about Americans of German birth; during the war many German Americans faced suspicion and harassment, and Congress passed the Espionage Act in June 1917.

    Homework passages. Wilson's message of February 26 (T6) and the part of the war message on aims, motives and German Americans (T7), used for the homework problems.

    That policy was forthwith put into practice. It has now been in active exhibition for nearly four weeks. Its practical results are not fully disclosed. The commerce of other neutral nations is suffering severely, but not, perhaps, very much more severely than it was already suffering before the 1st of February, when the new policy of the Imperial Government was put into operation.

    We have asked the co-operation of the other neutral Governments to prevent these depredations, but I fear none of them has thought it wise to join us in any common course of action. Our own commerce has suffered, is suffering, rather in apprehension than in fact, rather because so many of our ships are timidly keeping to their home ports than because American ships have been sunk.

    Two American vessels have been sunk, the Housatonic and the Lyman M. Law. The case of the Housatonic, which was carrying foodstuffs consigned to a London firm, was essentially like the case of the Frye, in which, it will be recalled, the German Government admitted its liability for damages, and the lives of the crew, as in the case of the Frye, were safeguarded with reasonable care.

    The case of the Law, which was carrying lemon-box staves to Palermo, disclosed a ruthlessness of method which deserves grave condemnation, but was accompanied by no circumstances which might not have been expected at any time in connection with the use of the submarine against merchantmen as the German Government has used it.

    In sum, therefore, the situation we find ourselves in with regard to the actual conduct of the German submarine warfare against commerce and its effects upon our own ships and people is substantially the same that it was when I addressed you on the 3d of February, except for the tying up of our shipping in our own ports because of the unwillingness of our ship-owners to risk their vessels at sea without insurance or adequate protection, and the very serious congestion of our commerce which has resulted, a congestion which is growing rapidly more and more serious every day.

    This in itself might presently accomplish, in effect, what the new German submarine orders were meant to accomplish, so far as we are concerned. We can only say, therefore, that the overt act which I have ventured to hope the German commanders would in fact avoid has not occurred.

    Woodrow Wilson, Why We Are at War, Message to Congress, February 26, 1917: the first four weeks of the new policy (six consecutive paragraphs) (1917). Public domain (published 1917). Source text.

    We have no selfish ends to serve. We desire no conquest, no dominion. We seek no indemnities for ourselves, no material compensation for the sacrifices we shall freely make. We are but one of the champions of the rights of mankind. We shall be satisfied when those rights have been made as secure as the faith and the freedom of the nation can make them.

    Just because we fight without rancor and without selfish objects, seeking nothing for ourselves but what we shall wish to share with all free peoples, we shall, I feel confident, conduct our operations as belligerents without passion and ourselves observe with proud punctilio the principles of right and of fair play we profess to be fighting for.

    [...]

    We enter this war only where we are clearly forced into it because there are no other means of defending our rights.

    It will be all the easier for us to conduct ourselves as belligerents in a high spirit of right and fairness because we act without animus, not in enmity toward a people or with the desire to bring any injury or disadvantage upon them, but only in armed opposition to an irresponsible Government which has thrown aside all considerations of humanity and of right and is running amuck.

    We are, let me say again, the sincere friends of the German people, and shall desire nothing so much as the early re-establishment of intimate relations of mutual advantage between us--however hard it may be for them, for the time being, to believe that this is spoken from our hearts. We have borne with their present Government through all these bitter months because of that friendship--exercising a patience and forbearance which would otherwise have been impossible.

    We shall, happily, still have an opportunity to prove that friendship in our daily attitude and actions toward the millions of men and women of German birth and native sympathy who live amongst us and share our life, and we shall be proud to prove it toward all who are, in fact, loyal to their neighbors and to the Government in the hour of test. They are, most of them, as true and loyal Americans as if they had never known any other fealty or allegiance. They will be prompt to stand with us in rebuking and restraining the few who may be of a different mind and purpose. If there should be disloyalty it will be dealt with with a firm hand of stern repression; but, if it lifts its head at all, it will lift it only here and there and without countenance except from a lawless and malignant few.

Differentiation Strategies

For Struggling Students

  • Give a support chart with the claims already copied in, so students only find and rate the support
  • Pre-teach six terms in one sentence each: submarine (U-boat), neutral, belligerent, armed neutrality, autocracy, memorandum
  • Start with the Warm-Up claim and one claim from T1 before moving to T3, which has the hardest language

For Advanced Students

  • Read the text of the Zimmermann note, which Wilson calls "eloquent evidence" in T5, and decide whether it supports the claim he attaches to it, the broader claim in T4, or both
  • Read the rest of the February 3 message and decide whether Wilson's promise there, "Only actual overt acts on their part can make me believe it even now," was met by the evidence he gave on April 2
  • Choose one claim rated asserted and write the paragraph Wilson would have needed to make it well supported, using only information available in April 1917

Assessment Guidance

What to Look For

Strong work quotes the exact claim, names the kind of support (document, example, number, testimony, principle, or none), tests the evidence for relevance, specificity and sufficiency, states the assumption behind the reasoning, and gives a rating that matches the tests. Watch for students who rate a claim by whether they agree with it, who treat a restated claim as evidence for itself, or who call a claim unsupported when the support is reasoning rather than evidence. A strong answer often splits one sentence into parts with different ratings, as Example 4 does.

Support Ratings Card Sort

20 minGroups of 3

Each group sorts eight claim cards from T1-T3 into three piles, well supported, partly supported and asserted, and writes on the back of each card the words that decided its pile.

The Eight Claim Cards

  1. "The new policy has swept every restriction aside." (T1 paragraph 3)
  2. Germany acted "because it had no weapons which it could use at sea except these" (T1 paragraph 5)
  3. Submarines "must be dealt with upon sight, if dealt with at all" (T2 paragraph 4)
  4. German submarines were "somewhat restrained" after April 1916 (T1 paragraph 1)
  5. Armed neutrality "is practically certain to draw us into the war" (T2 paragraph 6)
  6. From February 1, Germany would sink "every vessel" approaching the Allied coasts (T1 paragraph 1)
  7. The Allies used "brutal methods of war" (the German memorandum, T3 paragraph 9)
  8. "American ships have been sunk, American lives taken" (T2 paragraph 1)

Teacher Key

  • Well supported: card 6, by the memorandum Wilson quotes ("All ships met within the zone will be sunk," T3 paragraph 10); card 4, which Wilson concedes against his own interest and which fits the 1916 pledge (T3 paragraph 4)
  • Partly supported: card 1 (the policy is documented, the practice is described only by categories); card 8 (relevant, but no ship or person is named); card 3 and card 5 (clear reasoning, one vague link: "The intimation is conveyed")
  • Asserted: card 2 (a claim about Germany's reasons with no evidence in T1); card 7 (no Allied measure is named in the words quoted)
  • Accept other piles when the back of the card names the evidence or reasoning and the test that decided it

Discussion Questions

  • Which card was hardest to place, and was the difficulty about the evidence or the reasoning?
  • Card 4 is a point Wilson concedes. Does admitting something that weakens your side make an argument more or less convincing?
  • Is a claim supported by strong reasoning but no evidence "partly supported" or "asserted"? Agree on a class rule.

Variation for a Shorter Class

Use only cards 1, 2, 3 and 6, which cover all three piles, and sort them as a whole class.

Make It Checkable

15 minPairs

Pairs take two claims their group rated partly supported and write an "evidence request": the specific evidence that would move each claim to well supported. Then they trade requests with another pair, who judge whether the requested evidence would really do the job.

Procedure

  • Copy the claim and the words in the text that support it now
  • Write the request in four parts: what (the kind of document or fact), who (its source), when (its date) and how much (how many cases would be enough)
  • Explain in one sentence why that evidence would be relevant to this claim and not just to the topic
  • Trade with another pair; the other pair marks each request "would settle it," "would help" or "off target"

Teacher Key

  • For "Vessels of every kind" (T1 paragraph 3): names, dates and flags of ships sunk without warning since February 1, including at least one hospital ship and one relief ship, from a source such as the ships' owners or survivors
  • For "The intimation is conveyed" (T2 paragraph 5): the German statement itself, with its date and author, saying how armed guards would be treated
  • An "off target" request asks for evidence about the topic in general (for example, how many submarines Germany had) that would not show the claim true or false

Discussion Questions

  • Why might a President speaking to Congress leave out specifics that his listeners could have asked for?
  • Does leaving out evidence make a claim false, or only less supported in this text?

Modification for English Learners

Give the four parts of the request as sentence frames: "I need a ___ (what) from ___ (who), dated ___, showing ___ cases."

Four Corners: The Strongest Support

15 minWhole class

After the quiz, label the four corners of the room with the four parts of Wilson's case for war: the sinkings (T1), the failure of armed neutrality (T2), the broken pledge (T3) and the nature of the German government (T4-T5). Students stand in the corner whose support they judge strongest and prepare a 30-second defense with one quotation. Then they move to the corner they judge weakest and do it again.

Procedure

  • Two minutes of silent choice, with the support chart in hand
  • Each corner agrees on its best quotation and one speaker presents it
  • Any student may move after hearing the others; a mover must say which quotation moved them
  • Repeat for the weakest support

Teacher Key

  • There is no single right corner. A strong defense quotes evidence and applies a test by name (relevant, specific, sufficient, or the assumption behind the reasoning)
  • Push back on any defense that argues the war was right or wrong instead of saying how well the text supports it

Discussion Questions

  • Can an argument be persuasive to its first audience and still be partly supported in the text?
  • Which part of Wilson's case would you most want more evidence for, and where would you look for it?

RH.9-10.8 Homework: Testing the Rest of the Case

Directions: Use T6, Wilson's message of February 26, 1917, and T7, the part of the war message on aims, motives and German Americans, both printed in the Closure phase of the lesson plan. Use T1 where a problem names it. Quote the words you use and give the text and paragraph number. Answer Problems 1-5 in 3-5 sentences each; Problem 6 is a short essay.

Part 1: The February 26 Message (Problems 1-3)

  1. In T6 paragraph 3, Wilson names two American ships sunk since February 1, "the Housatonic and the Lyman M. Law." Compare this evidence with the evidence in T1 paragraph 3 for the claim that ships "of every kind" have been sunk. Which is more specific, and what does the difference suggest about how you should rate each claim?
  2. Wilson writes that American commerce "is suffering, rather in apprehension than in fact" (T6 paragraph 2). Explain whether this sentence supports or weakens a claim that American ships were being destroyed in large numbers, and what kind of evidence it rests on.
  3. In T6 paragraph 6, Wilson says that "the overt act which I have ventured to hope the German commanders would in fact avoid has not occurred." What would a reader need to see in the April 2 message (T1-T5) to accept that an overt act had occurred by then? Does the part of the message on this page supply it?

Part 2: Aims and Motives (Problems 4-6)

  1. "We have no selfish ends to serve. We desire no conquest, no dominion" (T7 paragraph 1). Identify the kind of claim this is, and explain what evidence, if any, a speech could offer for it. Then say how far T7 supports it.
  2. In T7 paragraph 6, Wilson claims that Americans of German birth "are, most of them, as true and loyal Americans as if they had never known any other fealty or allegiance," and predicts that disloyalty will appear "only here and there." Assess the support for the claim and for the prediction separately.
  3. Write a short essay of 200-250 words assessing the extent to which the reasoning and evidence on this page support Wilson's claim that "We enter this war only where we are clearly forced into it because there are no other means of defending our rights" (T7 paragraph 3). Use at least three of T1, T2, T3, T6 and T7, rate the claim, and explain which support is strongest and which is weakest.

Frequently Asked Questions

10 Questions

What does RH.9-10.8 mean?

RH.9-10.8 asks students in grades 9-10 to assess the extent to which the reasoning and evidence in a historical text support the author's claims. "RH" stands for Reading in History/Social Studies, "9-10" is the grade band and "8" is the eighth reading standard. The key words are "the extent": students judge how far each claim is supported, not just whether the argument is good or bad.

What is the difference between a claim, evidence and reasoning?

A claim is what the author wants you to accept; evidence is what the author offers as fact to back it; reasoning is the step that explains why the evidence, or a principle, leads to the claim. In Wilson's war message, "armed neutrality [...] is impracticable" is a claim, the German statement about armed guards is evidence, and the argument that a hidden submarine must be attacked on sight is reasoning.

How do students decide how well a claim is supported?

By testing the evidence and the reasoning separately. Evidence should be relevant to this claim, specific enough to check (names, dates, numbers, documents) and sufficient for how strong the claim is. Reasoning depends on an assumption, and students ask whether the text gives reason to accept it. The result is a rating, such as well supported, partly supported or asserted, with the words that decided it.

How is RH.9-10.8 different from RH.11-12.8?

RH.9-10.8 works inside one text: students judge the support the author gives. RH.11-12.8 asks students to evaluate an author's premises, claims and evidence by corroborating or challenging them with other information, so students bring in other sources to test the author. In grades 9-10, a claim can be rated weakly supported even if it later proved true, because the rating is about what the text shows.

How is RH.9-10.8 different from RI.9-10.8?

They ask for similar thinking. RI.9-10.8 is in the English language arts standards and asks students to delineate and evaluate an argument, judge whether reasoning is valid and evidence relevant and sufficient, and identify false statements and fallacious reasoning. RH.9-10.8 applies the same kind of judgment to historical sources in history and social studies classes, where the evidence is often documents, events and official reports.

Does rating a claim as weakly supported mean the author was wrong?

No. A true claim can be poorly supported in a particular text, and a well-supported claim can later prove false. Wilson's claim that Germany withdrew its pledge "without prior intimation of any kind" is weakly supported by the notes he himself quotes, yet the withdrawal itself is well documented; the rating reflects what the message shows, not a verdict on the decision for war.

Why use Wilson's 1917 war message to teach RH.9-10.8?

Because it is a short, famous argument that mixes kinds of support: German documents that Wilson quotes, reasoning a student can test step by step, sweeping generalizations and plain assertion. Reading it with his messages of February 3 and February 26 lets students check some claims against the evidence Wilson himself put before Congress.

What mistakes do students make with RH.9-10.8?

A common one is rating a claim by whether they agree with it. Another is treating a restatement of the claim in other words as evidence for it. Students also miss that a sentence can hold two claims with different support, as when Wilson says Germany withdrew its pledge "suddenly and without prior intimation of any kind." Asking "What exactly does this evidence show?" fixes most of these.

How is RH.9-10.8 assessed?

Usually with a primary-source argument and questions that ask which evidence best supports a claim, what assumption a piece of reasoning depends on, or which statement best evaluates the support for a claim. Written tasks ask students to judge an argument with quotations. The lesson's quiz uses both forms.

Which class teaches RH.9-10.8?

RH.9-10.8 is a literacy standard for history and social studies, so it is usually taught in grade 9 or 10 World History or U.S. History, alongside the content of the course. It builds on RH.6-8.8, which asks students to distinguish fact, opinion and reasoned judgment, and prepares for RH.11-12.8, where students test an author against other sources.
