摘要：ABSTRACT This study aims to determine the application of basic science concepts practicum modules that are designed by using the design of science process skills in practicum basic concepts of science to improve the ability of experimenting PGSD students. This study uses a pre-experimental design with cluster random sampling technique. The instruments used in this study were the learning outcomes sheet and the practical concept modules for the basic concepts of science that were designed using science process skills. The results of observations of the implementation of learning at each meeting were obtained at meetings 1,2, and 3 obtained by 81.58%, 85.44%, and 88.26% of students were able to carry out practical activities with the category of almost all activities carried out well.
