DEVELOPING PROBLEM SOLVING ABILITIES AND MATHEMATICAL CREATIVITY ON PROBABILITY OF EVENTS BY USING CREATIVE PROBLEM SOLVING OF MATHAYOM SUKSA III STUDENTS

Abstract

The purposes of this research were to: 1) to study the development of mathematical problem solving ability of mathayom suksa III students who received learning management using creative problem solving 2) to study the development of mathematical creativity of mathayom suksa III students who received learning by using creative problem solving and 3) to study the satisfaction of mathayom suksa III students towards learning management by using creative problem solving. The sample group was 36 mathayom suksa III students in class number 4 in the second semester of academic year 2019 from Kanchanapisekwittayalai Suphanburi School and was acquired by Cluster random sampling. The tools used in this research were 1) lesson plans with creative problem solving 2) Subjective test and 3) Satisfaction assessment form of learning management. The data were analyzed by Repeated measures ANOVA, calculating for mean and standard deviation. The results of the study were as follows: 1) Problem solving ability, the post-learning was higher than the pre-learning significantly at the 0.01 level; problem solving ability of mathayom suksa III students, the scores between-learning and post-learning were higher than the pre-learning significantly at the 0.05 level
2) Mathematical creativity, the post-learning was higher than the pre-learning significantly at the 0.01 level; mathematical creativity of mathayom suksa III students, the scores between-learning and post-learning were higher than the pre-learning significantly at the 0.05 level and 3) For mathayom suksa III students learning by creative problem solving have the satisfaction at the high level with the average score () = 3.90 and standard deviation (S.D.) was 0.58.
