The Development of Mathematics Learning Achievement on the Pythagorean Theorem of Grade 8 Students through Cooperative Learning Using the STAD Technique Combined with Problem-Solving Processes Based on the STEAM Approach

Abstract

The objectives of this research were: 1. To compare the mathematics learning achievement on the Pythagorean Theorem of Mathayom 2 students before and after learning through the Cooperative Learning Management using the STAD technique combined with the STEAM-based problem-solving process. 2. To compare the mathematics learning achievement on the Pythagorean Theorem using the Cooperative Learning Management using the STAD technique combined with the STEAM-based problem-solving process with the criterion of 70% of the full score. 3. To study the attitude towards learning mathematics on the Pythagorean Theorem of Mathayom 2 students who received the Cooperative Learning Management using the STAD technique combined with the STEAM-based problem-solving process. The sample group consisted of 35 Mathayom 2 students from Rungruang Uppathum School, selected using cluster random sampling.. The research instruments included: 1. Lesson Plans 2. Pre-test and Post-test 3. Attitude Assessment Form. Statistics for data analysis included the mean, standard deviation (S.D.), and t-test.The research findings revealed that: 1. The students' mathematics achievement scores after learning were higher than before learning, with a statistically significant difference at the .05 level. 2. The students' mathematics achievement scores were higher than the 70% criterion, with a statistically significant difference at the .05 level. 3. The attitude towards learning mathematics on the Pythagorean Theorem of Mathayom 2 students was at the highest level."
