THE DEVELOPMENT OF MATHEMATICS LEARNING ACTIVITIES ON NUMERALS OF NOT MORE THAN 100,000 BASED ON CONSTRUCTIVISM FOR PRATHOM SUEKSA THREE STUDENTS AT PHYATHAI SCHOOL

Abstract

In this thesis, the researcher develops (1) mathematics learning activities on numerals of not more than 100,000 based on constructivism with a criterion efficiency of 80/80; compares (2) the mathematics learning achievement on the topic with the set criteria of 70%, and examines (3) the students’ opinions with the mathematics learning activities under investigation. The target group was 37 students in Prathom Sueksa, 3/3 students at Phyathai School in the first semester of 2020. The research instruments consisted of the following: (1) eleven lesson plans with mathematics learning activities on numerals of not more than 100,000 for Prathom Sueksa Three students based on constructivism; (2) a 20-item learning achievement test with four multiple choices on numerals of not more than 100,000 with the index of item objective congruence (IOC) between 0.67 and 1.00, the difficulty range between 0.30 and 0.91, the discriminatory power between 0.28 and 0.70, and the reliability of the whole test at 0.86; and (3) a form to measure the student opinions with the instruction and study based on constructivism.

Findings are as follows: (1) The mathematics learning activities on numerals of not more than 100,000 based on constructivism for the students under study found to exhibit an efficiency of 83.66/81.22 by the criteria of 80/80. (2) The mathematics learning achievement on numerals of not more than 100,000 based on constructivism of almost all students passed the 70% criteria, which average mark of the overall students was 81.22% (3) The student opinions with the mathematics learning on numerals of not more than 100,000 based on constructivism for the students under study overall was at a high level with the mean of 4.49 from the five-rating scale.
