THE DEVELOPMENT OF MATHEMATICAL THINKING OF FIFTH GRADE STUDENTS BY USING LEARNING MANAGEMENT BASED ON FRAIVILLIG’S GUIDELINES FOR ADVANCING CHILDREN’S THINKING AND REAL-WORLD CONTEXTS

Abstract

This research is Quasi-experimental research. The objectives are as follows:
1) compare the mathematical thinking of fifth grade students before and after learning management based on Fraivillig’s guidelines for Advancing children’s thinking and real-world contexts 2) compare the mathematical thinking of fifth grade students after learning management based on Fraivillig’s guidelines for Advancing children’s thinking and real-world contexts with 70 percent criteria. The sample group in this research were 14 students in fifth grade at Watsali School, Suphanburi, in the second Semester of Academic Year 2022, that obtained from purposive sampling. Research tools include learning management plans based on Fraivillig’s guidelines for Advancing children’s thinking and real-world contexts to develop mathematical thinking. There are supporting documents to study the development of mathematical thinking of students, including activity sheets and records of the development of mathematical thinking. And finally, a mathematical thinking test. The data were analyzed by finding arithmetic means, standard deviations, and test hypotheses using t-test for dependent samples and t-test for one sample statistics. The results of the research were as follows: 1) The mathematical thinking of fifth grade students after learning management based on Fraivillig’s guidelines for Advancing children’s thinking and real-world contexts was higher than before at the statistical significance .05 2) The mathematical thinking of fifth grade students after learning management based on Fraivillig’s guidelines for Advancing children’s thinking and real-world contexts was higher than 70 percent criteria at the statistical significance .05. The students had developed their mathematical thinking in every component better respectively.
