The Development of Mathematics Lesson Plans Entitled “Addition with the Results Less Than 100,000” by Using Team Pair Solo Exercises for Third Grades Students at the Second City Network Group School at Ubonratchathani Primary Educational Service Area Office 1

Abstract

This research was aimed 1) to develop the mathematics lesson plans entitled “Addition with the Results Less Than 100,000 ” by using team pair solo exercises for third grades students to meet the standard criteria set at 80/80; 2) to find the effectiveness index of the mathematics lesson plans entitled “Addition with the Results Less Than 100,000 ”  by using team pair solo exercises for third grades students; 3) to compare the mathematics lesson plans entitled “Addition with the Results Less Than 100,000 ”  by using team pair solo exercises for third grades students pretests and posttests; and 4) to study the satisfaction of the mathematics lesson plans entitled “Addition with the Results Less Than 100,000 ” by using team pair solo exercises for third grades students at the second city network group school at Ubonratchathani Primary Educational Service Area Office 1. The sample of the study included 12 third grades students studying in the first semester of the academic year 2020 at Ban Na Muen School under Ubonratchathani Primary Educational Service Area Office 1 chosen by the multistage sampling. The instruments used in this study were 1) 14 Team Pair Solo lesson plans with evaluating of the lesson plans quality at excellent level 2) 14 exercises with the quality of excellent level 3) an academic achievement measure test with the reliability at 0.89; and 4) the satisfaction questionnaire with consistency at 1. The statistics used for analyzing data were percentage, mean, standard deviation, one sample t-test and dependent sample t-test.

The research found that:

1. The mathematics lesson plans entitled “Addition with the Results Less Than 100,000” by using team pair solo exercises for third grades students had an efficiency of 82.70/81.25 which was higher than the criteria set.


2. The effectiveness index of the mathematics lesson plans entitled “Addition with the Results Less Than 100,000 ” by using team pair solo exercises for third grades students at the second city network group school at Ubonratchathani Primary Educational Service Area Office 1 was 66.91 or 66.91%.

          3) Third grades students at Ban Na Muen school who learned the mathematics lesson plans entitled “Addition with the Results Less Than 100,000” by using team pair solo exercises for third grades students at the second city network group school at Ubonratchathani Primary Educational Service Area Office 1 after learning had higher achievement than before learning with the increasing development score at significantly statistics .05.

          4) Third grades students at Ban Na Muen school have the satisfaction of the mathematics lesson plans entitled “Addition with the Results Less Than 100,000” by using team pair solo exercises for third grades students at the second city network group school at Ubonratchathani Primary Educational Service Area Office 1 with excellent level.
