ChatGPT-generated help produces learning gains equivalent to human tutors on mathematics skills

This dataset contains 274 rows corresponding to the 274 learners participating in a 3x4 study where participants were randomly assigned to one of three mathematics hint conditions (ChatGPT, Human tutor, No hints) and one of four lessons from OpenStax Elementary Algebra, Intermediate Algebra, College Algebra, or Statistics textbooks. Participants were recruited from Mechanical Turk. Columns of the dataset contain the anonymous userID of the participants (anonUserID), the lesson they were assigned to, the hint condition they were assigned to, their percent correct on a three-item preTest and postTest, the sessionTime in seconds, the number of total questions answered (3 pre test + 5 condition + 3 post test), and the learningGain (post-test - pre-test).
