Acquisition of projectile motion concepts on phenomenon based physics' experiential learning

This research aimed to explore the concept acquisition in phenomena based experiential learning on projectile motion. Through phenomenon based physics' experiential learning, students analyze a phenomenon & link it with the existing concept so that it will be able to increase the acquisition of the concept. This research employed a mixed-method with an embedded experimental model. The data was obtained from test, interview, and observation on 26 tenth graders of Senior High Schools in Malang, East Java, Indonesia. Data was analyzed by N-Gain score and d-effect size. The students' concept acquisition was grouped based on a cognitive level and projectile motion concept. The results showed that the improvement of students' concept acquisition after taught with phenomenon-based physics' experiential learning. The average score of pretest and posttest is 29.96 and 77.69 with high N-gain and large d-effect size, 0.681 and 5.5 respectively. Concepts of velocity and acceleration on the projectile motion should be noticed using vector analyze in daily learning.
