Comparisons of MathematicsLearningBetweenConstructivismTheoryLearningAbility and the Tradition Learning Activities onLogic for Mattayomsuksa4Students

Abstract

This research aimed developing a lesson plan for mathematics learning activities based on constructivism theory that promoted student who studying at 1st grade of senior high school to have effectively critical thinking ability in logic according to criteria 75/75, studying the effectiveness index of mathematics learning activity lesson plan based on constructivism theory that promoted student who studying at 1st grade of senior high school to have effectively critical thinking ability in logic lesson, comparing the learning achievement and critical thinking ability of students studying with a learning activity lesson plan based on the constructivism theory concept that promotes critical thinking ability with normal learning activities in logic lesson of student who studying at 1st grade of senior high school. The sample groups used in this research were 2 classes that each had 36 students who studying at 1st grade of senior high school.The samples were obtained by Cluster Random Sampling. The research instruments were 18 lesson plans for mathematical learning activity lesson plans based on the constructivism theory and 18 lesson plans for normal learning activities on students who studying at 1st grade of senior high school. Test for measuring the learning achievement of 1st grade of senior high school, a total of 30 items with the power classified for each item was from 0.26 - 0.99, the difficulty was from 0.22 - 0.78, and the confidence in the whole version was 0.84. Critical thinking test consisted of 6 items had power classified into 0.36 - 0.52, the difficulty was 0.32 - 0.70, and the entire confidence was 0.52. The statistics used for data analysis were mean, standard deviation, percentage and hypothesis using t-test (Independent Samples).

       The research results appear as follows: The efficiency of the learning management lesson plan (E₁/E₂) of mathematical learning based on the constructivism was 78.07 / 76.48. The index of effectiveness was 0.6308 or 63.08 percent. The 1st grade of senior high school mathematics learning achievement by organizing learning activities based on the constructivism theory concept was higher than normal learning activities, that was significant at the 0.05 level. Finally, the results of the critical thinking ability test after the construction of constructivism theory were significantly higher than that of normal learning activities at 0.05 level.
