The STAD cooperative learning model can support active, independent and responsible learning for students. The application of this model is expected to improve students' critical thinking skills. The purpose of this study was to determine the improvement of students' critical thinking skills using Edmodo-assisted learning models. Edmodo was modified to become a teacher tool to expand learning at home. This research is an experimental study using a pretest-posttest control group design involving 39 students of class VIII MTs At-Taqwa Beru, Sikka, East Nusa Tenggara. Based on the results of the study it was found that the Edmodo-assisted STAD type cooperative learning model can improve students' critical thinking skills.

This research aimed to discover the validity and the feasibility of the learning videos on parabolic motion materials. These videos are provided for the flipped classroom activity. The output of this research is the product of learning videos that are valid and feasible used as learning media. This research develops with the ADDIE model using two videos, a video of physics concept analysis in daily life, and a video of teacher's explanation in the form of light board-based video. The validity average of learning videos from material experts is 94.44% for 1st-learning video, and 93.06% for 2nd-learning video. Besides, the validity average from media experts is 91.57% for 1st-learning video, and 90.19% for 2nd-learning video. Therefore, the validity is in the very valid category. The percentage average of students' responses towards the 1st-learning video is 90.02%; the 2nd-learning video is 98.37%. Hence, the student's responses to learning videos are categorized as very feasible. Based on validator and students' response evaluation results, learning videos are valid and feasible for learning media. This study can be a reference to produce effective and efficient learning media. The limitation of this research is that the effectiveness of the learning video had not been tested.
