THE EFFECTS OF LEARNING MANAGEMENT BY USING POLYA’S PROBLEM SOLVING PROCESS SUPPLEMENTED WITH BAR MODEL ON MATHEMATICS ACHIVEMENT AND MATHEMATICS PROBLEM SOLVING ABILITY FOR GRADE 5 STUDENTS

Abstract

The purposes of this research were to 1) compare the mathematics achievement of grade 5 students before and after learning management by using polya’S problem solving process supplemented with bar model 2) compare the mathematics achievement of grade 5 students after learning management by using polya’S problem solving process supplemented with bar model  with 75  percent criterion. 3)  compare the mathematics problem solving ability of grade 5 students after learning management by using polya’S problem solving process supplemented with bar model  with 75  percent criterion. 4) Study the satisfaction of grade 5 students towards on learning management by using polya’S problem solving process supplemented with bar model. The Sample consisted of 28 grade 5 students in the first semester of the 2024 at Ban Nakham School, Srichomphu Subdistrict, So Phisai District, Bueng Kan Province  by cluster random sampling. The research instruments were 1) lesson plans 2) the mathematics achievement test had difficulty values between 0.62 - 0.79, discrimination values between 0.30 - 0.48 and reliability values was 0.95 3) the mathematics problem solving ability test had difficulty values between 0.62 - 0.76, discrimination values between 0.31 - 0.48 4) the satisfaction questionnaire. The statistics for data analysis comprised; mean, standard deviation, percentage, t-test for dependent samples. The results of this research found that; 1) The mathematics achievement of grade 5 students after learning management by using polya’S problem solving process supplemented with bar model was significantly higher than before at the .05 levels. 2) The mathematics achievement of grade 5 students after learning management by using polya’S problem solving process supplemented with bar model was significantly higher than 75 percent criterion at the .05 levels. 3) The mathematics problem solving ability of grade 5 students after learning ,management by using polya’S problem solving process supplemented with bar model was significantly higher than 75 percent criterion at the .05 levels. 4)  The Satisfaction of Grade 5 students towards learning management by using polya’S problem solving process supplemented with bar model at a highest level
