# Relationship Of Variables With The Ability to Solve Mathematics Problems Of Matthayomsueksa 3 Students in Buriram Province

## Main Article Content

## Abstract

One of the main aims of organizing mathematics learning is to enable

students to solve mathematical problems which is a foundation used to develop

thinking methods and enhances their abilities in solving daily problems. In organizing

Mathematics learning, there are several relevant factors that relate to mathematics

problem-solving ability of students. This study was aimed at investigating relationship

between factors affecting mathematics problem-solving ability and constructing

predictive equations for mathematics problem-solving ability. The sample consisted of

370 Matthayomsueksa 3 students from 8 schools selected by multi-stage random

sampling method. Two research instruments used in this study were the four tests the

rating scale test and as follows. The first test was a 4-multiple choice test with 40

items to investigate mathematics problem-solving ability with the difficulty ranged

from .32 to .72, the discrimination ranged from .23 to .92 and the reliability of .892.

The second was 12-item reasoning ability test with the difficulty ranged from .40 to

.72, the discrimination ranged from .39 to .85 and the reliability of .453, The third was

12-item English Abilities test with the difficulty ranged from .36 to .66, the discrimination

ranged from .23 to .69 and the reliability of .349, The fourth was 12-item figure test

with the difficulty ranged from .36 to .64 and the discrimination ranged from .23 to .69,

and the reliability of .370 The 5-rating scale of factors affecting mathematics problemsolving ability test consisted of 4 sections and there were12 items in each section. The

first section investigated learning attention, the second section examined attitudes

towards mathematics, the third section explored self-concept and the fourth section

studied teaching quality with the discrimination ranged from .645 to .923 and the

reliability of .962. The statistic applied in this study was Stepwise Multiple Regression

Analysis.

The results of the study were as follows:

1. The results of the multiple correlation coefficients among each predictive

variable and criterion variable via stepwise selection revealed all predictive variables

were positively associated with the criterion variables at the level of significance of .01.

The predictive variable associated with the criterion variable at the highest was

teaching quality (X7) with the correlation coefficient of .933. The predictive variable associated with the criterion variable at the lowest was self-concept (X6) with the

correlation coefficient of .820.

2. The results of the predictive equations for mathematics problemsolving ability of Matthayomsueksa 3 students in Buriram Province revealed that the

four predictive variables including teaching quality (X7), reasoning ability (X1), learning

attention (X4) and attitudes towards mathematics (X4) affected mathematics problemsolving ability (Y) in terms of raw scores and standard scores as follows.

Raw Score Regression Equation:

Y/= 4.794 + .540X7 + .751X1 + .220X4 + .401X5
