Abstract
The purposes of this research were (1) to develop the learning activity management emphasized Heuristics thinking method with open-ended questions in ratio and percentage lesson of Prathomsuksa 6 students that had the efficiency at the set criteria, 75/75 (2) to compare the mathematical learning achievement and the mathematical reasoning abilities of Prathomsuksa 6 students who learn by the developed learning activity management and who learn by the ordinary learning activity management (3) to compare mathematical reasoning ability of Prathomsuksa 6 students between before and after learning by developed learning activity management (4) to study the student learning retension after learning by the developed learning activity management . The samples were the experimental group that was the 26 students of Banlak school, and the control group was 27 students of Chumchonbannoncharoen School. The research instruments were (1) 20 lesson plans of mathematical learning activity management with emphasized Heuristics thinking method with open-ended questions, (2) 20 lesson plans of ordinary learning activity management, (3) the 20 items of mathematics learning achievement test, (4) the 4 items of mathematical reasoning ability essay. The results of the study were 1) The developed lesson plans of mathematics learning activity management emphasized Heuristics thinking method with open-ended questions gave the efficiency, 84.88/79.62 2) The mathematical learning achievement and the mathematical reasoning ability of Prathomsuksa 6 students who learned by developed lesson plans were higher than students who learned by the ordinary lesson plan at the .05 level of significant. 3) The students’ s mathematical reasoning ability after learned by the developed lesson plans was higher than before learning at the .05 level of significant. 4) Students who learned by developed lesson has the learning retention.
