The Learning Management of the Concrete-Pictorial-Abstract Approach Combined with the Bar Model to Develop Mathematics Learning Achievement for Secondary 2 (Grade 8) Students

Abstract

This research aimed to 1) compare the mathematics learning achievement of secondary 2 (grade 8) students studying through the learning management of the Concrete-Pictorial-Abstract approach combined with the bar model with the criteria of 70 percent, 2) compare the mathematics learning achievement of secondary 2 (grade 8) students before and after studying through the learning management of the Concrete-Pictorial-Abstract approach combined with the bar model, and 3) study the satisfaction of secondary 2 (grade 8) students studying through the learning management of the Concrete-Pictorial-Abstract approach combined with the bar model.

The sample group consisted of 29 secondary 2 (grade 8) students who were studying at Innovation Demonstration School of Rajamangala University of Technology Thanyaburi in the academic year 2021 using purposive sampling. The research instruments were 1) the learning management plans with the Concrete-Pictorial-Abstract approach combined with the bar model learning management, 2) the mathematics learning achievement test, and 3) the satisfaction assessment form. The mean, standard deviation, and t-test were the statistical methods used for data analysis.

The research results were as follows: 1) the mathematics learning achievement of Secondary 2 (grade 8) students studying through the learning management of the Concrete-Pictorial-Abstract approach combined with the bar model was higher than the set criteria of 70 percent at the statistical significance level of .05, 2) the mathematics learning achievement of secondary 2 (grade 8) students after studying through the learning management of the Concrete-Pictorial-Abstract approach combined with the bar model was higher than the before at the statistical significance level of .05, and
3) satisfaction of secondary 2 (Grade 8) students studying through the learning management of the Concrete-Pictorial-Abstract approach combined with the bar model was at a high level.
