The Development of the Geometry Exercise Using the Geometer’s Sketchpad in Mathematics Learning Substance Group for Grade 5 Students
Main Article Content
Abstract
The objectives of this research were to (1) develop teaching using the geometry exercise-the Geometer’s Sketchpad on quadrilateral, triangle, and circle in mathematics learning substance group for Grade 5 students and (2) compare the student’s achievement of before and after teaching geometry using the geometry exercise. The subjects of this study were 15 Grade 5 students in the second semester of 2014 academic year at Watkuankoei School, Nakhon Si Thammarat. The instruments used for this research were: 1) the geometry exercise using the Geometer’s Sketchpad, 2) a learning achievement test, and 3) a learning management plan. The data were analyzed to determine mean, standard deviation, percentage, relative growth, and t-test.
The research results revealed that: (1) the teaching using geometry exercise had a process efficiency of 87.41 and product efficiency of 88.83 and (2) the students had a higher learning achievement after teaching at .001 levels of significance and relative growth at 69.92%.
