DEVELOPMENT OF MATHEMATICS LEARNING ACHIEVEMENT AND MATHEMATICAL CONNECTION ABILITY OF MATAYOMSUKSA 5 STUDENTS BY USING PROBLEM – BASED LEARNING MANAGEMENT

Abstract

This research is an action research. The objective is to develop of Learning Achievement and Mathematical Connection Ability of Mathayomsuksa 5 students in Interest and the value of money by using Problem – Based Learning Management to pass the criteria of 50 percent of the full score. The target group was 35 students of mathayomsuksa 5 students in the academic year 2019 from Borabuwittayakhan School, Borabu, Mahasarakram. They were selected by using Purposive Sampling for 1 classroom. The research instruments are lesson plans using problem – based learning on the topic of Interest and the value of money, Mathematical Connection Ability test, learning achievement test, the observation form, the interview form The data was analyzed by using mean, percentage and standard deviation.  In the research, it was found that: The Mathematical Connection Ability score of mathayomsuksa 5 students by using Problem – Based Learning Management is as follows: In the first, second, and third spirals, the averages are 35.00 percent, 46.07 percent, and 58.19 percent, respectively. In the third spiral, each of the students scores is higher than 50 percent of the full score. And learning achievement score is as follows: In the first, second, and third spirals, the averages are 29.43 percent, 45.43 percent, and 58.29 percent, respectively. In the third spiral, each of the students scores is higher than 50 percent of the full score. And, the Mathematical Connection Ability and learning achievement score is increased in each spiral. It showed that learning by using problem – based learning can develop the Mathematical Connection Ability and learning achievement of students.
