Development of Pre-Calculus Electronic Instructional Module (PEIM) Based on Least Mastered Competencies

This study aimed to develop and validate Pre-Calculus Electronic Instructional Module (PEIM) that is intended to innovate instruction and encourage learner engagement at the senior high school level. This descriptive developmental research used the ADDIE model which involved five phases: Phase I-Analysis; Phase II-Design; Phase III-Development; Phase IV-Implementation; and Phase V-Evaluation. During the initial phase of the study, the least mastered competencies in Pre-Calculus were identified and became the basis for the development of the material. It also revealed that students encountered challenges in learning independently, receiving limited teacher support, feedback delay, lack interactive elements of module, lack of motivation and limited access to resources. Thus, the PEIM is designed to be published online and available offline to ease access during remote learning setups and for learners using electronic devices such as smartphones, tablets, laptops, or personal computers with the help of Kotobee Reader. It features innovative and interactive elements including the following: AI text-to-speech, video lessons, graphics, animations, and interactive activities. Students and expert validators were purposefully selected to evaluate the developed e-module. The PEIM attained “Passed” ratings on content, instructional, and technical qualities. Pre-calculus teachers, mathematics experts, and students evaluated the PEIM as “Very Satisfactory.” The study further revealed that students performed better in Pre-Calculus after the implementation of the PEIM. The designed electronic modules are acceptable, recommended, and enhance achievements while providing a positive learning experience for students. Thus, PEIMs are recommended to be reproduced and implemented as one of the learning resources in Pre-Calculus for SHS students.
