Abstract

Research objective is to know the increasing students^s chemistry learning outcomes in class XI senior high school even semester after using electronic students worksheets with problem based learning models developed. Research type is research and development with ADDIE design. Data analysis technique is qualitative and quantitative descriptive. Analysis step showed that students need this product as learning sources. In design, product was designed using web. In development, product was validated by material and IT experts. It showed that product was feasible to be used in learning process. In implementation, product was used by students in buffer solution material. In evaluation, it showed that students^s n-gain in experimental class were better than control class. Right side t-test calculation showed that tcount (5.919) > ttable (1.668). It showed that there was effect of using electronic students worksheets with problem based learning model to increase students^s learning outcomes in buffer solution material.

Keywords: electronic students worksheets, problem based learning models, students^s chemistry learning outcomes
