Scientific Reasoning & Physics Conceptual Gains

For the 98 students in the earlier data set, we saw a significant correlation between the reasoning test scores and the normalized gains on the FCI. These students were in 6 different courses, with 4 different instructors, using different interactive techniques. (Three of the courses were summer sections with less than 10 students each.)

There is a significant correlation between the scientific reasoning scores and gains shown on the FCI (r=0.54, p<0.0001).

Among the various sections of the Lawson Test, proportional reasoning showed the strongest correlation with FCI gains (r=0.45, p<0.0001).

Students who scored in the lowest quartile on the LT had an average FCI gain of 0.26, while those in the highest quartile had an average gain of 0.67.
