The purpose of this study was to determine the effectiveness of hypertext media based kinematic learning and formal thinking ability to improve the conceptual understanding of physic prospective students. The research design used is the one-group pretest-posttest experimental design is carried out in the research by taking 36 students on from physics education program in one Institute for teacher education in Medan, Indonesia. The samples are given kinematics conceptual understanding tests before and after the hypertext media based kinematic learning, and also the samples are given test of logical thinking (TOLT) or test of formal thinking before learning. The results show that learning outcomes is significantly improved by using hypertext media based kinematic learning.
