A Study of Learning Achievment and Problem Solving Abilities in Pythagoras Theory of Mathayomsuksa 2 Students by Using KWDL Technique.

Abstract

The purposes of this research were: 1) To develop learning management plan on “Pythagoras Theory”of Mattayomsuksa 2 students through KWDL Technique to be efficient at the criterion of 70/70; 2) To compare learning achievement on “Pythagoras Theory” between pre and post learning of Mattayomsuksa 2 students through KWDL Technique; and 3) To compare the problem solving abilities on “Pythagoras Theory” between pre and post learning of Mattayomsuksa 2 students through KWDL Technique.  The samples were 20 Mattayomsuksa 2 students in a classroom of Wangmaipattana School, Tepsatit District, Chaiyaphum Province studying in semester 2 of academic year 2019. Samples were selected through simple random sampling by drawing lots.  The research design was the Pre-Experimental Design by One-Group Pretest-Posttest design.  The instruments used in this research included: 1) sixteen learning management plans on “Pythagoras Theory” unit of Mattayomsuksa 2 through KWDL Technique; 2) thirty items of objective learning achievement test on “Pythagoras Theory” unit with 4 choices of each item; and 3) four items of subjective learning achievement test on mathematic problem solving. The statistics used for the data analysis were percentage, mean, standard deviation and the hypothesis testing using the t-test (Dependent Samples). Results of the research were as the followings: 1) Efficiency of the learning management plan on “Pythagoras Theory” unit of Mattayomsuksa 2 through KWDL Technique was at (E₁/E₂) equal to 83.47/81.67 that was higher than the specified criterion of 70/70. 2) The learning achievement on “Pythagoras Theory” unit of Mattayomsuksa 2 students through KWDL Technique in post learning was higher than in pre learning with statistical significance at the level of 0.05 3) The problem solving abilities on “Pythagoras Theory” unit of Mattayomsuksa 2 students through KWDL Technique in post learning was higher than in pre learning with statistical significance at the level of 0.05
