Abstract:
Constructivism laboratory is a learning strategy, where theory and experiment which are in
progress at the same time. Experiments in this case use simple science media. This research
aims to improve the concept mastery of physic learning school I through the improvement of
student learning activities and the quality of simple science media made by students about
kinematics and dynamics. The instruments were used in collecting data: student activity
observation sheet, media quality assessment sheet, questioner of student motivation and
achievement test. The subject of this research is 25 students of physic education program. This
action research uses Kemmis model which based on 4 components research like planning, action,
observation and reflection. Based on data analysis, it can be shown that: the quality of simple
science media increased in each cycle which high category in third cycle. The learning
motivation increased from 2.9 to 3.1 in high category. The student physics concept achievement
is 65 higher than previous physic class, 62. So, it can be concluded that physics concept mastery
in “ physics school 1” for physics education students can be improved through learning activities
of constructivism laboratory.
