Laboratory Manual for Senior High School Physical Science Class

This study investigates the influence of laboratory manual that is virtual based as a supplementary tool or learning material in Physical Science class to improve Grade 11 learners’ conceptual understanding in Chemistry under MELCS. Utilizing a Quasi-experimental design with qualitative support research design, the study determines the effect of Laboratory Manual on learners’ conceptual understanding through quantitative assessment with qualitative supplemental data. The findings indicate a significant improvement in learners’ achievement, with posttest scores reflecting augmented comprehension of Chemistry concepts in Physical Science. The study reveals that developed laboratory manual utilizing virtual laboratories are effective tools for improving science education in resource-limited settings.
