THE DEVELOPMENT OF MATHEMATICS PROCESS AND SKILLS OF SURFACE AREA AND VOLUME BY DESIGN THINKING PROCESS OF NINTH GRADE STUDENTS

Abstract

The objectives of this research were 1) to compare the mathematics learning results on surface area and volume of ninth grade students before and after using the design thinking approach, 2) to study the development of mathematical skills and processes of ninth grade students after learning management through Design Thinking, 3) to study the satisfaction of ninth grade students with learning management through the design thinking. The sample in this research were 27 students of ninth grade class 4 Srakrachomsoponpittaya school in the first semester of the academic year 2020. The sample was selected by using the cluster random sampling method. The research tools were 1) unit plan of surface area and volume, 2) a mathematics learning test on surface area and volume, 3) assessment of mathematical skills and processes, 4) questionnaire on the satisfaction of ninth grade students towards learning management through the design thinking. The data were analyzed by mean score, standard deviation, and dependent t-test. The results of this study: 1) After using design-thinking learning management, the mathematics learning outcomes of ninth grade students were significantly higher than before at the .05 level. 2) Mathematics skills and processes of ninth grade students after learning management through design thinking was at a good level. 3) The satisfaction of ninth grade students with learning management through design thinking was at a high level.
