Effectiveness of Open Educational Resources (OER) in the Performance of Learners in Science 6

This study aimed to determine the Effectiveness of Open Educational Resources (OER) in the performance of learners in Science 6. In the pre-test administered, the control group obtained a higher mean percentage score (MPS) than the experimental group with mean percentage score (MPS) of 29.68 % and 29.00% respectively. In the post test, the learners in the control group obtained a mean percentage score of 80.18% and the experimental group had 86.33%. Both groups improved in their performances but the performance of the experimental group is much higher than the control group after Open Educational Resources (OER) was employed. Based on the results, this study concludes that Open Educational Resources (OER) in teaching Science is an effective tool in enhancing the performance of learners in Science 6.
