Abstract

The purposes of this research were to study the effective ways of using engineering design process based on STEM education and to promote collaborative problem solving competencies in motions topic for 10^th grade students. The participants were 45 10^th grade students. The research instruments included lesson plans,
the collaborative problem solving competency observation form, the collaborative problem-solving competency test, and the learning management observation. Data were analyzed through content analysis and the method of triangulation was employed to ensure the creditability of this research. The research results indicated that the effective ways to develop students’ collaborative problem solving competency comprised of 1) defining the interesting problem related to everyday life, 2) defining challenging workloads to the class including an experiment to solve the problem, work piece construction, and 3) testing the results, and encouraging students to reflect and evaluate their ideas with argumentation. Most of the students had high and medium levels of proficiency in collaborative problem solving competency in all three competencies. However, when considered the performance of students, the best competency of students was establishing and maintaining team organization, establishing and maintaining shared understanding, and Taking appropriate action to solve the problem, respectively.
