This paper aims to develop a student worksheet based on e-learning on valid momentum and impulse material to build on the problem-solving abilities of students in MAN 3 Yogyakarta. The method used is Research and Development (R&D) with a 4-D model (Define, Design, Develop, and Disseminate). The instruments used include validation sheets and tests. Data in the form of feasibility of e-learning madrasah-based student worksheet to improve students' problem-solving abilities. Data collection methods used in this study contain expert validation, observation, pre-test, and post-test. Data analysis using the sign test. The results showed that 1) the development of e-learning based worksheets with momentum and impulse material was feasible in terms of the validation results. This can be seen from the results of expert validation that show the feasibility of e-learning-based worksheets in improving problem-solving abilities is in the very high category and 2) the effectiveness of using elearning-based worksheets, namely those developed based on the data obtained from the pretest and posttest results can improve solving abilities. problem in the implementation class. So that student worksheet developed based on e-learning madrasah is suitable for improving problem solving abilities.
This research was conducted to determine the increase in problem solving abilities in senior high school students. This research method is experimental research, using 2 classes. Sampling using purposive sampling with certain considerations by knowing the conditions or situations under study. Modelling class and implementation class. Data collection used the pre-test and post-tests to determine the increase in students' problem-solving abilities. The results of the analysis using sign test analysis obtained from data collection show that in the modelling class the value of α = 0.003 is obtained. The implementation class gets a value of α = 0.001. The results of the analysis show α <0.05 that the modelling class has improved problem-solving abilities that are better for students after using the worksheet that has been developed compared to the implementation class.
