【Modern Japanese】 Evaluative Text Reading: Critiquing Arguments and Evaluating Validity in the Common Test

In the Modern Japanese (近代以降の文章) section of the Common Test, simply understanding "what the author wrote" is no longer enough. The exam tests evaluative reading (評価的読解): the ability to step back, examine the logical connections between claims and evidence, evaluate whether an argument is sound, and compare different texts or perspectives.

1. What is Evaluative Text Reading?

Evaluative reading means actively interrogating the text from multiple angles rather than passively absorbing it as absolute truth. In the Common Test, this skill is typically examined through questions asking you to:

- Evaluate the relationship between claims (主張) and grounds (論拠).
- Examine the validity (妥当性) and reliability (信頼性) of evidence and data.
- Spot logical jumps or unstated assumptions in an inference (推論).
- Evaluate companion materials, such as student discussion transcripts (話合い), study notes (ノート), or alternative texts offering counter-arguments.

2. Deconstructing Arguments: Claim (主張) vs. Grounds (論拠)

Every logical text is built around an architecture of assertions and justifications. When reading evaluatively, separate these two components constantly:

(1) The Claim (主張)

The author's core thesis, proposition, or conclusion (要旨・主張). Ask yourself: What exactly does the author want us to accept or believe?

(2) The Grounds (論拠)

The evidence, factual observations, statistics, or established principles provided to justify the claim. Ask yourself: Why should the reader accept this claim? What factual basis or reasoning supports it?

Key Evaluative Check: Does the ground actually support the claim? A common pitfall tested in exam questions is a logical leap (論理の飛躍), where a ground is factually true on its own, but does not sufficiently prove the specific claim the author asserts.

3. Checking Validity (妥当性) and Reliability (信頼性)

The official syllabus specifically highlights the treatment of information: examining 妥当性 (validity of reasoning) and 信頼性 (credibility of evidence and sources). In the exam, look out for three common evaluation points:

① Overgeneralization (個別と一般化のねじれ)
Does the author take a single isolated example or personal anecdote (個別) and treat it as a universal law for all society (一般化)? If an author argues that all young people lack focus based solely on observing three teenagers on a train, the reasoning lacks validity.

② Credibility of Evidence and Citations (引用・出典)
Are the cited sources, statistics, or quotes relevant and authoritative? Watch for quotes taken out of context or numerical data that measure something slightly different from what the author claims it measures.

③ Plausibility of Inferences (推論の仕方)
Examine whether the author assumes a false dichotomy (presenting only two options when multiple exist) or confuses correlation with causation (assuming event A caused event B just because they occurred together).

4. Evaluating Multiple Materials (複数の題材) and Discussion Transcripts

Common Test questions frequently pair an essay with a companion source—such as a second text with a differing viewpoint, a statistical chart (図表), or a classroom dialogue (話合い・ノート) between students analyzing the essay. To answer these evaluative questions accurately:

- Identify points of agreement and disagreement: In multi-text questions, clarify the shared theme (e.g., modern technology and memory) and pinpoint the exact divergence: does Text B refute Text A's premise, narrow its scope, or provide a fresh counter-example?
- Cross-reference text statements against student reflections: When a question asks which student's evaluation is valid, verify whether the student's summary accurately reflects the text's actual grounds, or whether the student mistakenly projected their own outside opinion.
- Connect figures and tables (図表) to text assertions: Determine whether a chart actually substantiates the author's claim or highlights a limitation or counter-trend that the author ignored.

5. Exam Strategy: How to Approach Evaluative Questions

① Ground your evaluation strictly in the provided text and materials.
Even in questions evaluating whether an argument is convincing, your evaluation must be based on the internal logic, textual evidence, and companion notes provided—never on personal outside impressions.

② Beware of choices that distort scope.
Incorrect options often exaggerate an author's measured conclusion into an absolute extreme, or misattribute another thinker's quoted view as the author's own.

③ Trace rhetorical devices (修辞) back to their argument function.
When metaphors (比喩), rephrasing (言い換え), or contrasting comparisons appear, identify why the author deployed them: to illustrate an abstract concept, expose an inconsistency, or reinforce their core claim.

Key Takeaway:
Evaluative reading elevates your reading from passive comprehension to critical analysis. By actively tracking the alignment between claims (主張) and grounds (論拠), checking the validity (妥当性) of inferences, and comparing complementary materials, you will master the highest-scoring reading questions on the Common Test.
