 Abstract

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.

 Ethical considerations

This study was conducted in accordance with ethical standards for research involving human participants. Approval to conduct the research was obtained from the Division of Cabanatuan City, Department of Education, and permission was granted by the administration of Cesar E. Vergara Memorial High School. Since the participants were minors, informed consent was secured from their parents/guardians, and assent was obtained from the students. Participation was voluntary, and students were informed that they could withdraw at any time without penalty. All data collected was kept confidential and reported anonymously to protect the identity of the participants.
