The mean score of the control group on the TOLT increased from 6.74 to 7.68 (+
0.94) while that of the treatment group increased from 6.74 to 8.84 (+ 2.10). The
improved posttest performance of the control group may be due to prior
exposure to the test in the pretest situation, maturation, or some interaction of
these factors. In view of the short time interval between pre- and posttests it
seems likely that prior exposure to the test may be the main factor responsible .... ~
for this improvement. The pretest aroused considerable interest and discussion
among students, which may have generated some cognitive changes.
