EFFECTS OF MATHEMATICS LEARNING ACTIVITIES ON SURFACE AREA AND VOLUMES USING KWDL TECHNIQUES ON PROBLEM SOLVING SKILL AND LEARNING ACHIEVEMENT OF MATHAYOMSUKSA III STUDENTS

Abstract

The purpose of this research paper was to develop mathematical problem solving skills and mathematics learning achievement on surface area and volumes of mathayomsuksa III after receiving learning activities using KWDL technique. The sample of this study was 52 volunteers, who had an exam score of the surface area and volumes in first semester lower than 60 percent of the criteria, in Mathayomsuksa III students in the second semester of academic year 2019 at Chonkanyanukoon School, Chonburi. The instruments used in study were, 7 lesson plans, mathematical problem solving skills test with reliability of 0.83 and mathematics learning achievement on surface area and volumes test with reliability of 0.85. The hypothesis were tested using t-test. The findings were as follows: 1) The mathematical problem solving skills on surface area and volumes of mathayomsuksa III after receiving learning activities using KWDL technique was statistically higher than the criterion of 60 percent of the exam score at the .05 level of significance. 2) The mathematics learning achievement on surface area and volumes of mathayomsuksa III after receiving learning activities using KWDL technique was statistically higher than the criterion of 60 percent of the exam score at the .05 level of  significance.
