THE DEVELOPMENT OF MATHEMATICS TEACHING WHICH INCLUDES PROBLEM SOLVING MULTIPLICATION AND DIVISION USING THE BAR MODEL THEORY FOR PRATHOMSUKSA 4 STUDENTS PATONGWITTAYAMULNITHI SCHOOL

Abstract

The purposes of this research were to: 1) develop the mathematic learning packages on solving multiplication and division word problems by using the bar model theory to be effective according to the criteria of 80/80, for prathomsuksa 4 students patongwittayamulnithi school      2) compare the academic achievement between before-study and after-study of the groups using the learning kit and those not using the learning, 3) compare academic achievement After studying between the group that used and the group that did not use the learning kit., and       4) study satisfaction with using the mathematic learning packages. The population used in the research is 8 classrooms prathomsuksa 4 students of patongwittayamulnithi school. The sample group in this research was two classrooms prathomsuksa 4 students of patongwittayamulnithi school, using simple random sampling, which is the lottery method. The research instruments used were: 1) the mathematic learning packages, 2) the learning achievement tests, and             3) the satisfaction surveys. The statistics used in data analysis are means, standard deviation, means comparison of two dependent groups, and means comparison of two independent groups. The results of this research were: 1) learning packages consists of advice from teachers and students, objectives, learning content. Lesson plan, knowledge sheet, exercises with answers Mini-test with answers had an efficiency value of 83.63/82.75, 2) students who used the learning package had higher learning achievement after studying than before studying, statistically significant at .05, 3) the learning achievements of students who did not use learning packages than before studying, statistically significant at .05, 4) students who used the learning packages had higher learning achievement after studying than students who did not use the learning packages, statistically significant at .05, and 5) student satisfaction with the learning packages was at a good level.
