This study aims to determine the feasibility of inquiry-based electronic student worksheets assisted with worksheets to train visual-spatial on molecular geometry topics. The 4-D development research type according to Thiagarajan, Define, Design, Develop, dan Disseminate was applied in the study. However, it was adapted into 3-D because it was only at the development stage. The results showed that the developed e-worksheets obtained 85.92% for content validity and 86.67% for construct validity with a very feasible category. The practicality of electronic worksheets in student activities was 97.98%, and student responses obtained a percentage of 93% with a very decent category. The N-Gain calculated the effectiveness of e-worksheets obtained 0.94 in the high category. The inquiry-based e-worksheets are feasible for training visual-spatial on molecular geometry materials.

This study aims to: (1) knowing the needs analysis in the development of module based craft and entrepreneurial of green economy, (2) Examine the appropriateness of modules craft and entrepreneurial based on green economy, (3) Analyze the effectiveness of the module craft and entrepreneurial on green economy, to improve learning outcomes in entrepreneurship students.Research and development of craft and entrepreneurship module uses 8 of 10 step development of Borg and Gall which has been modified by Sugiyono. Analysis of the data used for the development of descriptive analysis, probability analysis module is based on the score criteria by using t-test.Based on results of the descriptive analysis of the validator module craft and entrepreneurial based on green economy obtained results are: (1) expert learning materials at 86.20 with very good criteria; (2) a media expert at 89.82 with very good criteria; (3) a linguist at 100 with very good criteria; (4) expert practitioners amounted to 93,89 with very good criteria. Based on the results of analysis the validator it can be concluded that the module craft and entrepreneurial based green economy worthy be used to improve students learning outcomes.The result of posttest test in the control class has an increase from the pretreatment of 69,86 up to 70,92 and the experimental class experimental test has increased from the average value of 69,53 which experienced an increase in posttest i.e. the mean value to 83, 71. Learning outcomes show that the craft module and entrepreneurship are able to improve student learning outcomes on the subject of craft and entrepreneurship. This is evidenced by the increase in student learning outcomes in the experimental class higher than the control class.
