THE DEVELOPMENT OF MATHEMATICS LEARNING ACTIVITIES BY USING A CONSTRUCTIVIST APPROACH WITH K-W-D-L FOR MATTHAYOM SUEKSA SIX STUDENTS

Abstract

This research was the development of mathematics learning activities by using a constructivist approach with K-W-D-L for matthayom sueksa six students on the topic of statistics. The sample consisted of 40 students from the Demonstration School of Ramkhamhaeng University using simple random sampling with lottery method. The research instruments were five mathematics lesson plans based on the constructivist approach with K-W-D-L on the topic of statistic with quality level 4.62, a 20-question with four choices learning achievement test with 0.26-0.78 difficulty index, 0.27-0.77 discrimination index and 0.84 reliability and a 10-item students’ satisfaction questionnaire with five level rating scale and 1.00 index of item objective congruence. Data analysis involved calculating means, standard deviations, percentages, and performing a dependent samples t-test. The findings revealed that: 1) The mathematics learning activities, consisting of four steps including (1) introduction, (2) idea exchange and problem-solving using the K-W-D-L technique, (3) conclusion, and (4) application, were efficient with values of 81.13/80.25. 2) Students’ learning achievements significantly increased after the lesson at the 0.05 level and 3) Students’ satisfaction with the learning activities was rated high ( = 4.49, SD = 0.52).
