AI help for reading comprehension without the shortcut summary

The fastest way to skip a reading assignment is to ask AI for a summary. How Nexus's class modes keep students reading, finding evidence and stating the main idea themselves.

[ READING COMPREHENSION ]

Summaries are the shortcut to watch

US reading scores were falling before ChatGPT: NAEP 2024 grade 12 reading was 10 points below 1992 and 3 points below 2019. AI adds a new risk on top. In seven experiments with 10,462 adults, people who learned from AI summaries ended up with shallower knowledge than people who used web links. On PISA 2025, students who used AI to draft, summarize or research scored lower in science than non-users; that is a correlation, not proof.

The skill a reading class builds is the one a summary skips: finding the main idea and the evidence for it.

How the three learning modes work in reading comprehension

Modes describe how a class is set up to respond, and students cannot change a class's mode. AI can make mistakes; before any pilot we check Hints and Guided with real models.

Mode	What the student gets	Good for	Watch for
Hints	A question that sends the student back to the text: "Which sentence supports that?"	Main idea, inference, evidence questions	Requests to summarize the whole text
Guided	One step at a time: annotate, find the claim, find the evidence, explain	Close reading and text-dependent writing	The AI quoting evidence the student should find
Full answer with critique	A complete response with a critique of its use of evidence	Reviewing a finished response	Using it before the student has read the text

A hint-first exchange

Study assistantHints

StudentWhat's the main idea of this passage? "The town council closed the library on Sundays to save money. Within a month, attendance at its after-school homework club fell by half, and the council reopened the library on weekends."

Study assistantWhat do you think it is? Then point to the sentence that supports your answer.

StudentThe library closed to save money.

Study assistantThat's what happened first. What changed by the end, and why does the passage mention the homework club?

StudentThe club lost half its students, so the council changed its mind.

Study assistantSo what is the passage really about: the closing, or what the closing cost?

StudentThat closing the library had a cost the council didn't expect.

Study assistantGood. Write that in one sentence, then name the detail that proves it.

Illustration: written by the Nexus team to show how a Hints class is designed to respond. It is not a transcript of Nexus output. Real answers vary by model, and AI can make mistakes.

Class instructions teachers can add

Each class can carry the teacher's own instructions on top of its mode. A few that work well here:

"Do not summarize assigned texts. Ask the student to summarize first, then give feedback."
"Ask the student to quote the evidence before explaining it."
"For vocabulary, ask the student to guess from context before defining."
"Keep questions tied to the text the student pasted."

Checking what students can do alone

Short unaided reading checks on a new passage show the skill directly: one main-idea question and one evidence question take five minutes. Classroom quizzing improves learning, g = 0.50 across 222 studies. In class chats, a pattern of summary requests on assigned reading tells a teacher who is skipping the text.

Questions and answers

Is it OK for students to use AI summaries of assigned reading?

It skips the skill. In seven experiments with adults, people who learned from AI summaries ended up with shallower knowledge than people who used web links. In a Hints class, Nexus is set up to send students back to the text.
