The purpose of this study was to investigate the effect of computer simulation Instruction (CSI) on students' achievements: Carrying out chemical experiments to acquire chemical concepts for eleventh grade students. The subject of the study consisted two sections of a one girl's high school in Jordan. One section was randomly assigned to experimental group in which computer simulation Instruction (CSI) was used, and the other section was randomly assigned to control group in which students were instructed by using the traditional teaching instruction.
The findings indicated that there is progress on the part of the experimental group which used the computer simulation Instruction (CSI) and this was reflected positively in the students’ achievement in carrying out chemical experiments to acquire chemical concepts.
