q2 i? In an NSF-supported study with a control group starting chemistry first, students taking CLASP first quarter showed grade increases of 0.59, 0.62, and 0.43 grade-points over the course average in the three chemistry quarters (p < 0.001, p < 0.001, p < 0.03), while the control group's marginal advantage was not significant. → Potter 2012

q2 · i2 · causal · r1

Study under NSF CCLI grant DUE-0633317 comparing a group taking CLASP first quarter before general chemistry against a control group starting chemistry first; the control group's performance was marginally above the roughly 380-student course average but not statistically significant (p > 0.05). No effect size is printed.

"The grade increase for the first quarter of chemistry was 0.59 grade-points ( p < 0.001), for the second quarter 0.62 ( p < 0.001), and for the third quarter 0.43 ( p < 0.03)."
