DEVELOPMENT OF A MODEL TO PROMOTE MATHEMATICALTHINKING AMONG UPPER SECONDARY SCHOOL STUDENTS USING SELF - DIRECTED LEARNING AND PROJECT - BASED LEARNING

Abstract

The objectives of this research are as follows: 1) to develop a learning model based on self - directed learning and project - based learning to enhance mathematical thinking; 2) to study the effectiveness of implementing the developed learning model based on self - directed and project - based learning in the aspect of mathematical thinking and the satisfaction of learning model based on self - directed learning and project - based learning. The subjects of research were 35 Grade 11 students who were selected by the cluster random sampling and attended 32 periods at 50 minutes per period in the first semester of the 2023 academic year. The research instruments consisted of a lesson plan based on self - directed and project - based learning, a mathematical thinking test and a questionnaire on satisfaction through model of learning. The data were analyzed by using mean, standard deviation and t - test. The results revealed the following: 1) the learning model was based on self - directed learning and project - based learning and had four main components; principles, objectives, steps of teaching and assessment and evaluation of learning model. The steps of learning model consisted of seven steps: 1) observing the needs of the students; 2) selecting learning problems; 3) problem - solving; 4) learning outside the classroom; 5) managing the learning process; 6) summarizing and presenting; and 7) reflection and the learning process. ; (2) the results of the effectiveness of implementing the developed learning model demonstrated the following: 2.1) the post - test mathematical thinking scores of the upper high school students were significantly higher than the pre - test at .05 level; the mean scores on the pre - test was 18.69 (S.D. = 4.40) . On the other hand, the mean scores of the post - test were 48.81 (5.71); and 2.2) overall student satisfaction through self - directed learning and project - based learning was at the highest level ( = 4.76, S.D. = 0.46)
