Development and Validation of Learning Package in Precalculus

The development of instructional materials is seen as a vital educational goal for addressing the needs of all students and ensuring quality education. As educational paradigms evolve, there is a growing emphasis on creating resources that engage, empower, and cater to the individualized learning of students. The study endeavored to develop and evaluate Modules in Precalculus for Grade 11 STEM students. The study employed the research and development (R&D) design and descriptive research method, utilizing the evaluation rating sheet for print resources adopted from the Department of Education. The passed-not-passed method was used to determine the extent of validity of the developed modules. Five experts in the field of mathematics and language evaluated the learning material, and the data were analyzed using frequency count, mean, and summation. The newly developed learning material in Precalculus wraps up eleven (11) modules. The presentation of the topics embraces the 5E instructional model in achieving the targeted learning outcomes grounded on the Most Essential Learning Competencies (MELCs). As a result, the Modules in Precalculus for Grade 11 STEM students exhibited remarkable substance and met the standards and requirements of the evaluation process. The developed modules augment the existing learning resources used for teaching the subject in Senior High School.
