Development and Validation of Electronic Laboratory (e-Lab) Manual in General Physics 1

This study focused on the development and validation of an electronic laboratory (e-Lab) manual designed to cover selected midterm topics in General Physics 1, including measurement, speed, velocity, acceleration, projectile motion, circular motion, and Newton’s Laws of Motion. The manual was carefully aligned with the Department of Education’s Most Essential Learning Competencies (MELCs) to ensure curricular relevance and applicability. Seventy Grade 11 students participated in its implementation, using the manual as an interactive and accessible digital resource to strengthen their competencies in physics. Expert evaluation revealed that the manual achieved a “Very Satisfactory” rating across three domains: content quality (3.86), instructional quality (3.80), and technical quality (3.85). These scores confirmed that the manual met standards of accuracy, organization, instructional soundness, and multimedia integration. In terms of effectiveness, student performance showed significant improvement. Results of the paired t-test analysis yielded a computed value of 14.1 with a p-value less than 0.05, leading to the rejection of the null hypothesis. This demonstrated a statistically significant difference between pretest and posttest scores, validating the positive impact of the e-Lab manual on learning outcomes. The study concludes that the electronic laboratory manual was effective in enhancing student competencies in General Physics 1. It recommends the development of similar manuals for other physics topics and emphasizes the importance of teacher training and workshops to integrate digital tools into instructional practices, thereby fostering meaningful and engaging learning experiences.
