In Table 4, it can be seen that the experimental group students' mean score of post-test (x = 16.86) and the
mean score of retention test (x = 16:46), are higher than the mean score of pre-test (x = 10.11). In addition, no
difference has been observed between the post-test and retention test according to the Tukey test. In this
case, when the averages are taken into consideration, the post-test scores of students have increased
compared to the pre-test scores; therefore, it can be said that the students have learned the subject of
enzymes being discussed according to the Multiple Intelligence Theory. It has been observed that the success
levels after the implementation have not changed in accordance with the scores obtained from the retention
test, so it can be said that the effect of the implementations based on Multiple Intelligence Theory continues.
