The Development of the Open Approach Learning Management Plan to Improve the Mathematical Achievement Learning on the Topic of Two-Dimensional and Three-Dimensional Geometry Shapes Using GeoGebra Program for the First Grade Students of Khoa Yoi Witttaya School

Abstract

The purposes of this research were; 1) to study the effectiveness according to E1/E2 quality criteria of 70/70 of the learning  management plan using the open approach on the topic of two-dimensional of three-dimensional geometry shapes with the GeoGebra program applied on the first graders of Khao Yoi Wittaya School, 2) to compare the mathematical achievement learning of students on the topic of two-dimensional and three-dimensional geometry shapes with the GeoGebra program for the first grade students of Khao Yoi Wittaya School before and after using the open approach. 3) to study the satisfaction of the first grade students of Khao Yoi Wittaya School on the learning management process using the open approach on two-dimensional and three-dimensional geometry shapes with the GeoGebra program. The research tools were an open-approach learning management plan on two-dimensional and three-dimensional geometry shapes, three learning management plans, the 20 multiple-choices tests on two-dimensional and three-dimensional geometric achievement tests, and an open approach assessment. The results were as follows: 1) the effectiveness of the open approach learning management plan on the two-dimensional and three-dimensional geometry with the GeoGebra program at Khao Yoi Wittaya School has an efficiency of 70.65/70.74, which is higher than compared with quality criteria of 70/70, 2) The mathematical achievement learning of the first grade students on two-dimensional and three-dimensional geometry shapes with the GeoGebra program of Khao Yoi Wittaya School was different between before and after using the open approach learning management plan because the test scores after using the open approach were 0.05 level of significance which higher than the test scores before using the open approach, 3)  The first grade student satisfaction on the learning management process using the open approach learning management plan on the two-dimensional and three-dimensional geometry shapes with the GeoGebra program were divided into four areas: atmospheric, instructor, teaching, and the outcome that affect the learner. The students were satisfied with the activities of the open approach learning, and the satisfaction level was good.
