The effect of OMO learning on high school students' problem-solving skills in physics

Online-merge-offline (OMO) learning in a hybrid learning space is becoming a popular pedagogy to enhance students' blended learning using appropriate technology. This investigation delves into the impact of OMO learning on developing physics problem-solving skills among high school students. A ten-week intervention employing OMO learning is implemented with 34 participants in both the experimental and control groups at a high school in Hangzhou, China. The efficacy of OMO learning is assessed through a quasi-experimental design encompassing pre- and post-assessments. The findings of this inquiry reveal: (1) The experimental group's physics problem-solving abilities are significantly impacted by OMO learning; (2) the use of cognitive tools rationally, the integration of online and offline collaborative learning, rich learning resources, and heuristic teaching all help students become more adept at solving physics problems; and (3) the cognitive load, students' lack of prior knowledge, poor self-regulation, and lack of help-seeking techniques all work against the improvement of students' physics problem-solving abilities. Suggestions are made in line with the research results and aims.
