Developing the Abilities to Solve Physics Problems of Eleventh Graders Through Learning Activities that Emphasize the Integration of Metacognitive Strategies with a Scaffolding Approach

Abstract

Background and Aims: "Students' ability to solve physics problems" is an important skill that helps develop analytical thinking and systematic reasoning, as well as promote a deep understanding of natural laws and phenomena, which can be effectively applied in real life and other science learning. This research aimed to develop the problem-solving ability in physics among Grade 11 students, ensuring that at least 70% of the students achieve a passing score.

Methodology: The target group consisted of 12 Grade 11 students during the first semester of the 2022 academic year at Jikduwittaya School, under the Secondary Educational Service Area Office of Ubon Ratchathani and Amnat Charoen. The research instruments were divided into three categories: Tools for research implementation: Learning activity plans focusing on solving physics problems. Tools for reflecting research outcomes: Behavior observation forms and student interview forms. Tools for evaluating research outcomes: Physics problem-solving ability tests for Grade 11 students. The research utilized an action research methodology divided into three cycles. Quantitative data were analyzed using mean, standard deviation, and percentage, while qualitative data were interpreted and summarized descriptively through observations and interviews.

Results: The students' passing rates for each cycle were as follows: Cycle 1: 2 students (16.67%) met the criteria, Cycle 2: 7 students (58.33%) met the criteria, Cycle 3: 9 students (75%) met the criteria.

Conclusion: These results indicate that the learning activities, which integrated metacognitive strategies with scaffolding techniques, effectively improved the students' problem-solving abilities in physics.
