The Development of Learning Activities Using STAD Cooperative Learning Model Focusing on Problem Solving and Mathematical Connections Skills on Linear Equation with One Variable for Mathayomsuksa 1

Abstract

This research aimed 1) to develop lesson plan using STAD cooperative learning model focusing on mathematics problem solving skill and mathematical connection skill and lesson plan using the traditional teaching methods on a linear equation in one variable of mathayomsuksa 1 students to have the efficiency criteria of 75/75 2) to fine the effectiveness index value of lesson plan 3) to compare the learning achievement between the group using STAD cooperative learning model and the group using the traditional teaching methods 4) to compare ability on problem solving and ability on mathematical connection between the group using STAD cooperative learning model and the group using the traditional teaching methods The sample groups used in this research were 80 students of mathayomsuksa 1, Lamplaimat School, Burirum province have 2 class by cluster random sampling. Include the class using STAD cooperative learning model focusing on Mathematics problem solving skill and mathematics connection skill and the class using the traditional teaching methods The tools used were lesson plan using STAD and lesson plan using the traditional teaching methods 2) Learning achievement test The confidence value is 0.99 3) ability on problem solving and ability on mathematics connection test The confidence value is 0.80

               The results of the study were as follows 1) Lesson plan using STAD cooperative learning model focusing on mathematics problem solving skill and mathematical connection skill on a linear equation in one variable to have the efficiency 82.70/81.87 and lesson plan using the traditional teaching methods on A linear Equation in One Variable to have the efficiency 80.60/76.60, which was higher than the required criteria. 2) Lesson plan using STAD cooperative Learning have the effectiveness index value of learning was 0.6284 and lesson plan using the traditional teaching methods have the effectiveness index value of learning was 0.5237 3) student the group using STAD cooperative learning model have learning achievement higher than the group using the traditional teaching methods. They were statistically different  significant at .05 level. 4) student the group using STAD cooperative learning model have ability on problem solving and ability on mathematics connection higher than The group using the traditional teaching methods They were statistically different significant at .05 level.
