“The present study took place during the Fall 2023 semester in Physical Sciences 2 (PS2), which is an introductory physics class for the life sciences and is Harvard’s largest physics class (N = 233). Students were randomly assigned to two groups, respecting the constraint that students who regularly worked together in class during peer instruction were placed in the same group in order to maximize the effectiveness of their in-class learning. The demographics of the two groups were comparable (see table S2A), as were previous measures of their physics background knowledge “
“Learning gains were measured by comparing the post-test scores of the AI group and the in-class active learning group to the pre-test scores of the two groups combined. Students in the AI group exhibited a higher median (M) post-score (M = 4.5, N = 142) compared to those in the in-class active learning group (M = 3.5, N = 174). The median learning gains for students, relative to the pre-test baseline (M = 2.75, N = 316), in the AI-tutored group were over doubleFootnote 5 those for students in the in-class active learning group.”
In other words, people who are going to take the final exam, put the textbook on the shelf , and , porospectively never do Physics again. Not really eliminating university. I’d guess if they tried even something like experiments with LASERs in their homes, the outcones for the two grops would differ substantially. But I am really glad this kind of instruction will work its way dowm to homeschoolers .
This was in 2023—when AI was much much dumber than it is now?
Stunning.
