Table 1.
Descriptive statistics for students who did and did not respond to requests for interviews.
Differences were tested by the Mann-Whitney U-test, and p-values have not been corrected for multiple comparisons.
Table 2.
Guiding and follow-up questions for student interviews.
Not all questions were asked exactly as written.
Table 3.
List of issues that arose from qualitative analysis of student interviews.
Percentages shown are the fraction of the students in the respective course performance category that listed that attitude or practice. Note that the in-class interactions 12–15 are based only on the students who were in the companion course (N = 17); the remaining issues are based on the entire sample. The * indicates a practice mentioned by a very small number of students and we caution the reader that inference is quite limited.
