Development and evaluation of a self-learning module for mastering basic science process skills

This study developed and validated a self-learning module designed to help Grade 8 Junior High School students acquire basic science process skills independently. The module, containing adapted and modified activities, was tested at Cesar E. Vergara Memorial High School using a pretest–posttest control group design. While both groups showed low initial scores, students who used the module achieved significantly higher posttest results than those taught through traditional instruction, indicating its effectiveness in improving knowledge and application of science process skills. Validation by science teachers confirmed the module’s clear objectives, logical organization, appropriate illustrations, safety measures, and accessible materials, as well as the adequacy of its evaluation tools. Overall, the module effectively enhanced students’ skills and promoted independent, confident learning.
