Abstract
The purpose of this study is to develop basic physics experiments (BPE) to improve the mastery concept of physics preservice teacher on Meldes law. Research and development (R&D) method is done by involving physics preservice teachers as many as 18 students in the first year and 15 students in second year as research sample. The research instrument uses a mastery concept multiple choice test and Student Worksheet (SW) based on Science Process Skills (SPS) that has been reviewed which includes observing, communicating, classifying, measuring, inferring, predicting, identifying variables, constructing hypotheses, defining variable operationally, designing experiments, acquiring and processing data to the conclusion. The results of the first year of study showed that the students SPS has not been trained optimally, the students still have difficulty in observations, determining experimental variables, inferring and hypothesis. This resulted in the low mastery of the concept with the average score of 44.44. In the second year, experimental activities were developed by emphasizing the basic Science Process Skills tracing at the beginning of the lecture through simple experimental topics in a more complex. Based on the second year research data processing showed improvement of science process skill (SPS) of students and there is an increase of average score of 73,22. Based on the results of research, it can be conclude that the development of basic physics experiments based on SPS has been done to improve the mastery concept of physics preservice teacher students on Meldes law material.
