The same students were tested at the ends of two consecutive school years; pre-test and post-test scores were compared to determine if differences post-test means of standard scores were compared to determine if differences were statistically significant after subtraction of the three standard score points gain expected of the students. Significance of differences was determined by use of Student's t-test for differences between correlated pairs of means. [...]
