Improving of Creative Problem-Solving Abilities through Activities in Lessons on Gas Properties and Rate of Reactions of Mathayomsuksa 5 Students

Abstract

This classroom research in sciences class aimed to improve creative problem-solving abilities of students. The study group was 20 Mathayomsuksa 5 students of a school in Bangkok. The content of the designed activities of lessons focuses on gas properties and rate of reaction. The research instruments were: 1) Activities of gas properties and rate of reaction, 2) Student on task behavior observation tool, and 3) Creative problem-solving assessment adapted from Osborn's seven-step CPS concept. The quantitative data were analyzed by using descriptive statistics, while qualitative ones were analyzed by content analysis.

            The research results revealed that students were able to create a “DIY Set: Rate of Reaction Tool Kit”. Throughout the activities, students worked collaboratively to identify and analyze problems, develop and test solutions, and improve their problem-solving methods, leading to receiving successful outcomes. Finally, the students’ creative problem-solving abilities were reported at a good level.
