The main purpose of this study is to examine the effect of teaching through the "Collaborative Strategic Reading (CSR) Model" on the reading comprehension skills at primary fourth grade. As a consequence, it was concluded in the study that the pre-test means were close to each other in the experimental and control group and that the experimental group had a higher mean than the control group in the post-test mean scores. Moreover, no significant difference was obtained between the experimental and control groups regarding the pre-tests. Still, a significant difference was obtained in favour of the experimental group for the post-tests. On the other hand, whereas it was determined that there was no significant difference between the experimental and control group for the pre-tests of Reading Comprehension and Main Theme Determination scales, there was a significant difference in favour of the experimental group for the post-tests and gain levels. It was also concluded that the value p which corresponded to Z=0,58 in the Pearson Product-Moment equation was 0.082 (p>0,05), and considering that the result was not significant, the pre-test/ post-test prediction level was not significant, and the power degree of the correlation between them did not present a significant difference.
