The Development of Learning Achievement, Problems-Solving Thinking Skill of Mattayomsuksa 6 Students by Problem based Learning coorperated with KWL Plus Techniques

Abstract

ABSTRACT
The objectives of this study were 1) to develop learning achievement by problem-based learning coorperated with KWL Plus technique in chemistry subject of Mattayomsuksa 6 students passing the criterion of 70 percent of full score, 2) to develop problem solving thinking skill by problem-based learning coorperated with KWL Plus technique in chemistry subject of Mattayomsuksa 6 students passing the criterion of 70 percent of full score. The sample used in this study consisted of 31 Mattayomsuksa 6/1 students in the 2nd semester of 2019 academic year of Thachangratbamroong school. The instruments use in the study were 1) the lesson plans of problem-based learning coorperated with KWL Plus technique, 2) the learning achievement test, and 3)the problem-solving thinking skill test. The statistics used for analyzing data were the percentage, mean and standard deviation ; and one sample t-test.
The results of the study were as follows :
1. The learning achievement of students who learning with the problem-based learning coorperated with KWL Plus technique was higher than the criterion of 70 percent of the full score with statistically significant at the .05 level with an average score of 24.58 (¯X = 24.58).
2. The problem-solving thinking skill of students who learning with the problem-based learning coorperated with KWL Plus technique was higher than the criterion of 70 percent of the full score with statistically significant at the .05 level with an average score of 21.48 (¯X = 21.48).
