A Study on Physics Learning Achievement in Projectile Motion of The Students in Mathayomsuksa 4 at Phanom Thuan Pittayakhom School by Using Projectile Launcher Activity Set with Ping Pong Ball

Abstract

The purpose of this research was to compare the pretest - posttest of physics learning achievement in projectile motion of the students in Mathayomsuksa 4 by using projectile launcher activity set with ping pong ball. The sample group used in this research was 25 students in Mathayomsuksa 4, Phanom Thuan Pittayakhom School, Kanchanaburi Province, the second semester of the academic year 2021, with a method of purposive sampling. The research instruments were projectile launcher activity set with ping pong ball, learning management plan, physics learning achievement test, research statistics such as mean, standard deviation, t-test for dependent samples. The results showed that, students’ learning achievement of posttest in physics subject on projectile motion was higher than pretest at the statistical significance level of .05
