Enhancing Science Concept Mastery of Challenged Grade 7 Learners Through PISA-Inspired Lessons: An Action Research

According to current PISA findings, Filipino students continue to perform poorly in science, which highlights the need for teaching strategies that improve conceptual comprehension and scientific reasoning. A group of Grade 7 challenged students at Dalipuga National High School continuously showed signs of struggling to grasp important science skills, especially when it came to deciphering diagrams, describing particle motion, and applying ideas to practical contexts. The usefulness of PISA-Inspired Lessons in enhancing the science concept understanding of ten purposefully chosen challenged learners was investigated in this action research. The learners were administered a validated PISA-aligned pretest before the intervention and a parallel posttest following several weeks of training using a one-group pretest–posttest design. The Wilcoxon Signed-Rank Test was used to assess quantitative data.
