Performance of Senior High School in Physics Problem-solving using Blended Learning Strategies

Abstract

The problem-solving skills in physics of senior high school students in Romblon, Romblon, Philippines was assessed during the pandemic period. Assessment was done with blended learning strategies utilizing internet connection to access lesson materials for self-directed learning. Lessons covered were in kinematics and students were provided with assortment of printed or digital modules, powerpoint explainer videos and lectures in google meet. Participants were twenty-one (21) students from Romblon National High School for the school year 2021-2022 and were purposively selected in the quantitative experimental research. Their performances were determined using the validated and reliable test questions in physics based on WISE problem-solving strategy. Analyses of data used the following statistical tools: Percentage, Mean, Standard Deviation, Analysis of Variance (one way), Kruskal -Wallis H test, T-test of dependent samples, Wilcoxon W-test, and Hedge’s g test. The study concluded the blended learning strategies used were effective in improving the problem-solving skills. The most notable were the use of digital modules, powerpoint explainer videos and messenger for communication and support to students. Easy access to learning materials manifested to students. Difficulties in derivation of a formula by transposing the variables in equation to derive a working formula for solving the unknown were observed.
