PowerPoint is one of the programs that has made classrooms more colorful and attractive with its multimedia incorporation. The present research has examined the effectiveness of early elementary science modules prepared with attributes of PowerPoint show for students independent and autonomous learning. The modules were prepared for the subject of sixth-grade science, employing programmed learning principles. This experimental study has compared two groups of sixth grade; each group having N=30, at public and private schools parallelly, with a pretest, posttest control group design by introducing PowerPoint mediated modules for four weeks for one hour daily. The pre and post-test achievements were compared through the ttest. Both study groups at public and private sector schools increased their conceptual ability and performed better than the control group participants on a fifteen-item multiple choice objective type test. The study holds implications for the effectiveness of PowerPoint modules for bridging individual differences, adding learner autonomy and pace and place free independent learning, specifically, for underprivileged students.
