A1 صالح، مدحت محمد حسن AB The study aimed at investigating the effect of using PDEODE strategy in developing achievement and higher cognitive processes in science among 4th grade elementary pupils in Saudi Arabia. The sample composed of 77 pupils divided into two groups: the experimental group (n=39) that studied the two selected subjects material changes & forces and movement according to PDEODE, and the control group (n=38) that studied the two subjects following the traditional way. An achievement test was prepared in the subjects selected as well as a test for the higher cognitive processes in science. Both tests were administered pre and post the intervention. The study showed that there are significant statistical differences at 0.01 level between the score means of the experimental group and those of the control group in the dependent variables for the experimental group. A significant correlation between achievement and higher cognitive processes was found within the experimental group, whereas no statistical significant correlation between them was found among the control group pupils.
