Effectiveness of Khan Academy videos on students' learning performance in simplifying the order of operations

Abstract

This quasi-experimental research utilized the 60 grade 8 students of Tapaz National High School during the School Year 2022-2023. To analyze the gathered data, frequency counts, percentages, mean, and standard deviation were used. The significant difference between the two groups was determined through the t-test at 0.05 alpha. The findings of the study are the following: Before the intervention, the control group and experimental group had very poor and poor learning performance, respectively. After the intervention, both the control group and experimental group obtained fairly satisfactory learning performance; There is no significant difference in the pretest scores of the control group and experimental group; Significant differences existed in the pretest and posttest scores of the control and experimental groups. Finally, the study found no significant difference existed between the posttest scores of the two groups. Thus, the use of Khan Academy videos as intervention in simplifying the order of operations appears to be ineffective.
