Mean and standard deviation (SD) for TTCI_PRE, TTCI_POST, and c _T for individual S11, F11, S12, and F12 semesters and total data pooled across semesters. Within semesters, mean TTCI_PRE and TTCI_POST values followed by different letters are significantly different (p < 0.01) in Paired-Samples t tests (TTCI). N = sample size. A perfect score on the TTCI is 14.
