Abstract:
Purposes The purposes of this research were to study the symbolic convergent thinking and the mathematical problem solving ability of Prathom Two students, and to study the relationships between the symbolic convergent thinking and the mathematical problem solving ability. Procedures Two tests were constructed by the researcher, the first test was the symbolic convergent thinking test and the second was the mathematical problem solving test. The tests were examined by the experts and were used to test in order to develop the tests The reliability coefficient of the first test was .823 and the second test was .844. The tests were administered to 240 Prathom 'two students of eight schools that are in the Division of Elementary Education, Department of General Education, Ministry of Education. The t - test, One-Way Analysis of Variance, T - Method and Pearson's Product Moment Correlation Coefficient were used for analyzing the data. Results The major findings of this research were as followed; 1.The ability to analyse and apply the mathematical problem solving were significatly different at the .01 level. There were significant differences between the symbolic convergent thinking in the form of relations and transformations at the .01 level, in the form of systems and transformations at the .05 level. 2.The correlation coefficient between the mathematical problem solving ability and the symbolic convergent thinking were .496.
