THE DEVELOPMENT OF MATHEMATICS REASONING AND ACHIEVEMENT BY CONSTRUCTIVISM THEORY WITH COOPERATIVE LEARNING AT THINK – PAIR - SHARE TECHNIQUE FOR GRADE 10 STUDENTS

Abstract

Abstract

          The purposes of this research were as follows. 1) To compare mathematical achievement Of grade 10 students before and after using constructivist theory with collaborative learning at Think – Pair - Share technique 2) To develop mathematics learning  management  based on constructivist theory with collaborative learning at Think – Pair - Share technique compared to the 70 percent threshold. 3) To study mathematical reasoning ability grade 10 students by using constructivist theory with collaborative learning at Think – Pair - Share technique compared to the quality. 4) To study the satisfaction Of grade 10 students after learning by using constructivist theory with collaborative learning at Think – Pair - Share technique. The sampling of this research were grade 10 students, 66 students in the first semester of Sirindhorn Rajawittayalai School, year 2019. The 2 classes of 8 classrooms were the units of the sampling, devided by simple random sampling. The tools of this research were : 1. Lesson Plan using the deductive teaching with using constructivist theory together with collaborative learning at Think – Pair - Share technique. 2. The pre – posttest of mathematics achievement and 3. The measure of the ability to reason mathematically, and The satisfaction rating of mathematics. Analyze data using a percentage, average, arithmetic, standard deviation, and dependent t – test value test results as follows :

1. The mathematics achievement of the students after using constructivist theory together with collaborative learning at Think – Pair - Share technique is higher than before. The statistics level is 0.05


2. The mathematics achievement of the students after using constructivist theory together with collaborative learning at Think – Pair - Share technique has an average rating of up to 74.24 percent higher than 70 percent. The statistics level is 0.05


3. The mathematical reasoning ability of the students after using constructivist theory together with collaborative learning at Think – Pair - Share technique have the ability to reason mathematically by a good level.


4. Students were satisfied after learning by constructivist theory together with collaborative learning at Think – Pair - Share technique overall was good.
