Researcher preview of the Study 2 pilot, one sample problem

Try First, Then Ask: what students see and what we record

Pick a condition and work the problem on the left. The right side shows the data the website records. In the study, researchers assign each student one link to one condition. Students see only the student screen. They do not see these condition tabs or the researcher view.

Student screen

Problem 1 of [6], independent-samples t-test
Scenario. A researcher compared test scores for two groups of students. Group A studied with practice questions. Group B reread their notes. Does the average score differ between the two groups? Use the information cards to answer.

Information cards

Click a card to read it. One card shows at a time.

1. Which row of the t-test table should you read?
2. What is the p value for the group difference?
3. What can you conclude at the .05 level?

Four sample students, same scoring

Invented examples to show the calculation. The no-AI baseline of 5 cards is a placeholder. In the study, it comes from the real no-AI group on each problem.

What the website records

VariableWhat it means
card_clicksEvery card click, including repeats
cards_totalDifferent cards opened on the problem (0 to 6)
card_secondsSeconds each card stayed open, card by card
cards_before_aiCards opened before the AI answer appears or the first tutor message
cards_after_aiNew cards opened afterward, which shows checking
steps_saved(No-AI mean cards − cards_total) ÷ no-AI mean cards
ai_opened_secTutor: seconds until the first message
first_answer, final_answerTry first: both answers
try_first_reasonTry first: the one-sentence reason, coded later with ICAP (Chi & Wylie, 2014)
answer_changedTry first: final answer differs from first answer
tutor_messagesTutor: students' typed messages, coded later with the Study 1 codebook and with ICAP (Chi & Wylie, 2014)
tutor_steps, hints_usedTutor: steps right or wrong, and hints needed
accuracyQuestions correct out of 3
decision_confidenceConfidence that the answer is correct, 0 to 100
metacognitive_self_esteem[Six] items after the last problem, [1 to 7]. Samples: "I am good at thinking," "I feel good about my ability to think through problems"
time_on_taskSeconds on the problem

The website only saves the text. Trained coders code students' messages and reasons after data collection. The website does not code anything itself.

One week later

Students take an ungraded quiz in class through a lockdown browser. There are no cards and no AI. All items are new, and none repeats a practice problem. Each item has a 0 to 100 confidence rating.

OutcomeSample item
Memory ([5] items, one per key concept)What does Levene's test check?
When do you read "Equal variances not assumed"?
What does a p value mean?
What p value makes a difference statistically significant?
What do you conclude when p is .05 or higher?
Application ([5] items)A new SPSS output and scenario: which row do you read, what is the p value, and what do you conclude?
Calibration = confidence − accuracy, averaged across items
Example: 90% confident on an item answered wrong: 90 − 0 = +90 (overconfident)
Example: 40% confident on an item answered right: 40 − 100 = −60 (underconfident)

Calibration uses the quiz and not the class task, because task accuracy can reflect help from the AI.

Prototype only. The sample output is computed from the means and SDs shown, except Levene's F and p, which are example values. The tutor replies here are scripted around four steps. For the pilot, API calls will make the tutor adaptive, with the same rules: give feedback on every reply, never repeat a question word for word, and never state the final answer. Study data will be stored on secure UM systems, and AI will run on a local LLM or a UM-approved setup. No data leaves this page.
