The Development of problem-solving ability on surface area of volume of Mathayomsuksa 3 students using problem-based learning and flipped classroom techniques

Abstract

          The purpose of this research was to: 1) Develop problem-based learning activities with the flipped classroom. To promote the development of problem-solving skills. Surface Area and Volume of Mathayomsuksa 3 2) Compared to the 60 percent criterion and 3) evaluate the development of the problem-solving ability on surface area of volume of students after learning via the developed activities. The samples were 40 Mathayomsuksa 3 students who were studying in the first semester of academic year 2019 at Islamic College of Thailand, Bangkok, received from using the cluster random sampling. The classroom was Mathayomsuksa 3 section 3 with 40 students. The research instruments included: 1) 12 activity learning management plans with a good level quality and series of VDO media, and 2) Problem-solving ability test. The Statistics used in data analysis were: One Sample t-test, and Relative change score.

          The results indicated that: 1) the flipped classroom consisted of two parts which were: 1.1) out-of-class learning self-studying by learning via series of VDO media, and 1.2) inside classroom organizing by allowing teacher take a role as facilitators during the 5 processes of problem-based learning namely: 1.2.1) Understanding of problem, 1.2.2) Planning and researching, 1.2.3) synthesizing of knowledge, 1.2.4) summarizing and evaluating processes, and 1.2.5) presenting and evaluating; (2) The students’ ability in problem solving in terms of understanding of problems after learning via the developed activities was significantly higher than the committed standard of 60% at the level of .05.; and (3) Most of students had the average score at a moderate level. students had the score of development at a moderate level with the percentage of 65% while the students who had the score in moderate level to very high level were 85%.
