Figure 2: Pre-test and post-test performance for MS4 and MS5 students completing the dermatology PALMs.

Figure 2:

For all students, post-test performance (gray) for both accuracy (upper) and fluency (lower) were statistically higher than pre-test performance (black) and with large effect sizes. For MS4s, P<0.0001; d=1.8 to 2.5, and for MS5s, P<0.0001 to P=0.014; d=1.5 to 3.9. Fluency appears consistently higher for MS5s than MS4s but differences are only statistically significance for the distribution pre-test (p=0.03; d=1.1) and the morphology post-test (p=0.03; d=0.94); statistical significance for the distribution post-test fluency was borderline (p= 0.07; d=0.99).
