 All Years Pre-test percent correct Post-test percent correct Significance YCBA Group (n=81) 50% (+0.10) 57% (+0.09) p=0.0001 Control Group (n=65) 47% (+0.10) 46% (+0.11) p=0.200

Figure 1: Mean raw score for each photograph from students receiving Set A as a pre-test in 1999-2000

Figure 1 shows the mean raw score of each photograh for the subjects assigned to the control and the YCBA groups who received Set A as the pre-test in 1999-2000. Photographs 1, 2, 3 were used as the pre-test and photographs 4, 5, 6 as the post-test. Figure 1 shows that subjects in the YCBA group improved in each one of the photographs representing their post-test score.

Figure 2: Mean raw score for each photograph from students receiving Set B as a pre-test in 1999-2000

Figure 2 shows the mean raw score of each photograh for the subjects assigned to the control and the YCBA groups who received Set B as the pre-test in 1999-2000. Photographs 4, 5, 6 were used as the pre-test and photographs 1, 2, 3 as the post-test. Figure 2 shows that subjects in the YCBA group improved in each one of the photographs representing their post-test score.

Figure 3: Percentage of subjects whose pre-test and post-test scores showed No Improvement, remained the Same or Improved by group assignment.

Figure 3 Improvement (I) between pre-test and post-tst scores defined as an increase in score of +5%. Same (S) defined as a score difference › -5% and ‹ +5%. No Improvement (NI) defined as a score difference -5%. Figure 3 shows the percent I, S, NI for subjects assigned to the control and the YCBA groups in both years 1998-1999 and 1999-2000.
