Development of tools problems-based learning model assisted by virtual experiment to increase students' generic science skills

Abstract

Type of research is research and development (R &D). This development research aims to produce physics learning tools using qualified problem based learning model assisted by virtual experiment has a valid, practical, and effective which to increase students generic science skills in subject of optical instruments. In this study, the generic skills that discussed on the science field, called generic science skills. The development model had used a four-D model consisting of define, design, develop and dessiminate phases. Trial of product conducted in students of eleventh grade of the state senior high school 1 east Praya in second semester the academic year 2018/2019and the method used was pre experiment. Generic science skills (GSS) was measured using student worksheet when the learning process was descriptively analyzed based on descriptors appeared on the observational sheet. Based on GSS observation data, that students were in the category "skilled" and "highly skilled".
