Learning management using Think Talk Write Learning Activities techniques to improve Mathematical problem solving ability for Mathayomsuksa 2 students

Abstract

          The purpose of this research were 1) to develop lesson plans using Think Talk Write on Statistics for grade 8 (Mathayomsuksa 2) students with the efficiency 75/75 criteria. 2) To compare the ability to solve mathematical problems of grade 8 students using Think Talk Write on Statistics between before class and after class. 3) To study satisfaction of students towards Think Talk Write learning activity for grade 8 students. The samples were 44 students from Mathayomsuksa 2/3 at Kalasinpittayasan School in the academic year 2021, selected by cluster random sampling technique. The research instruments were as follows: 1) 5 lesson plans totaling 10 hours. 2) The subjective test to measure the ability to solve mathematical problems for 5 items. 3) The achievement test in the form of four-option multiple choice questions for 30 items. 4) The satisfaction of students questionnaire towards Think Talk Write learning activity for 10 items. The statistics used in the research were percentage, the average, standard deviation, formular of the efficiency of learning activity, and T-test dependent sample. 
          The results shown as follows: 1) The efficiency of lesson plans using Think Talk Write on Statistics for grade 8 students was 77.18/76.14, which meets the determined criteria. 2) The ability to solve mathematical problems of grade 8 students, using Think Talk Write technique on Statistics, in after class was higher than before class with the significantly different at the statistical level of .05. 3) The satisfaction of students towards Think Talk Write learning activity was at high level; the average is 4.01 and S.D. is 0.08.
