The Development of Instructional Model to Enhance the competency of Mathematical Thinking of Secondary School Students
The purposes of this study are to: 1) develop the model to enhance the competency of mathematical thinking in secondary school students, and 2) study the result of the model enhancing the competency of mathematical thinking in secondary school students. The participants are 20 Mattayomsuksa three students (the third year of Junior High School) in Rajadhivas School, Bangkok, Thailand. The data were analyzed by using arithmetic mean, standard deviation, and content analysis. The research findings are as follows: 1) Competency of mathematical thinking in secondary school students consists of one key purpose, one key roles, three key functions, six unit of competencies, and seventeen element of competencies, 2) The process and instructional model includes: (1) context, principles and objectives, (2) the process and the model of enhancement including classroom activity preparation, inside and outside classroom activities (3) learning assessment of knowledge and the competency of mathematical thinking, 3) The results of applying the model to enhance the competency of mathematical thinking in Secondary School Students also shows that: (1) the students’ achievements after applying the model to the class are significantly higher at 0.5, (2) the overall achievement of the students in mathematical thinking stands at a good level, and (3) the students are satisfied towards the instructional model to enhance the competency of mathematical thinking; the satisfaction stays at a high level.
