标题：Development of Heuristics Problem Solving, and Learning Achievement of Grade 9 Students by Using Learning Management Focusing on Heuristics Approach in Thailand
摘要：The objectives of this research were: 1) to develop students’ Heuristics Problem Solving ability so that not less than 70% of them would have their Heuristics Problem Solving ability in “Good” level up, and 2) to develop the students’ learning achievement so that the students would have average score not less than 70% up. The target group included 36 Grade 9 Students, Nongbuapittayakan School, under jurisdiction of the Office of Nongbualampoo Secondary Educational Service Area 19, the Office of Basic Educational Commission, Ministry of Education, Thailand, by using Action Research including 3 practice spirals. There were 3 kinds of instruments including: 1) the instrument using for experimentation consisted of 15 Learning Management Plans by using Learning Management focusing on Heuristics Approach, 2) the instruments using for reflection the practice performance consisted of the Finding Record Form after learning management, the Learning Management Behavioral Observation Form, the Students’ Interview Form, and the Problem Solving Ability Test after learning, and 3) the instrument using for evaluating the Learning Management Efficiency consisted of the Learning Achievement Test. Data were analyzed by calculating the Mean (x), Standard Deviation (S.D.), Percentage, and Content Analysis. The research findings found that: 1) there were 29 students out of 36 students or 80.56%, being taught by using the Learning Management focusing on Heuristics Approach, had Heuristics Problem Solving Ability in “Good” level up which was passing specified criterion, and 2) the students being taught by using the Learning Management focusing on Heuristics Approach, had average learning achievement = 14.72 or 73.60%, and there were 26 students or 72.22% of them passing specified criterion.
