Development and Validation of a Worktext in Electromagnetism

This experimental and developmental study aimed to develop and validate a worktext in Electromagnetism. Thirty-nine students underwent the traditional approach, while a total of 40 students used the worktext in Electromagnetism. Mean, mean percentage scores, Analysis of Covariance (ANCOVA), and the coefficient of concordance were used to analyze the data gathered. Findings revealed that the worktext in Electromagnetism is valid and can be used by Physics students and teachers to supplement the teaching-learning process. After exposure to the two teaching methods, the students’ performance in the experimental group improved from Did Not Meet Expectations to Very Satisfactory and from Failed to Passed. In contrast, the performance of the control group improved from Did Not Meet Expectations to Satisfactory and from Failed to Passed. The control and experimental groups are comparable in terms of their performance in Electromagnetism. Though there is no significant difference in the posttest mean scores of the two groups, it is worth noting that the experimental group has a higher mean score than the control group. In addition, the experimental group performed as well as the control group, which consisted of performing students.  Instructional materials like worktexts and textbooks are effective materials in enhancing and facilitating the learning process. The validators are in agreement in their evaluation of the worktext.
