DEVELOPMENT OF COLLABORATIVE PROBLEM SOLVING COMPETENCY ON 11TH GRADE STUDENTS BY USING PROBLEM BASED STEM LEARNING MANAGEMENT IN THE TOPIC OF ELECTROCHEMISTRY การพัฒนาสมรรถนะการแก้ปัญหาแบบร่วมมือของนักเรียนชั้นมัธยมศึกษาปีที่ 5 โดยการจัดการเรียนรู้ตามแนวสะเต็มศึกษาที่เน้นการใช้ปัญหาเป็นฐาน เรื่อง ไฟฟ้าเคมี

Abstract

The purpose of this quality research was to develop 11th grade students’ collaborative problem solving competency by using problem based STEM learning management in the topic of electrochemistry. The participants were 29eleventh grade students. The methodology of this research was a classroom action research, through 3 continuous cycle. There were 6 steps in learning approach: 1) problem confirmation, 2) problem clarification, 3) planning, 4) contingency planning, 5) plan reorganization, and 6) assessment. The data were collected from the collaborative problem solving student’s behavior observation forms student’s activity sheet and students’ artifact. In data analysis, the content analysis approach was employed and the credibility was verified by method triangulation. The result indicated that students’ collaborative problem solving competency increased from first to third cycle of the classroom action. The best developed competency of students was establishing and maintaining group organization, followed by selecting an appropriate action to solve the problem and establishing and maintaining shared understanding, respectively. Research finding suggest that teaching needs using a real life problem such as choosing a battery car type, increasing value by electroplating, connecting the lamp when the power goes out and the activity should provide student to practically solve the problem.
