Developing Instructional Video Media on Prehistoric Periodization for Social Studies Learning

This research and development aims to develop learning videos for preliterate periodization material that are valid according to media experts, material experts, language experts and teachers and are effective for use in learning. This research is research and development (R&D). The model used in this development research is the Ten Steps to the Development of the Borg and Gall Model. The development stages include research and gathering initial information, planning, initial product development, expert validation testing, first product revision, small-scale testing, second product revision, large-scale field testing, final product refinement, and product dissemination and distribution. The subject of this research is Class VII E MTsN 2 Blitar students, totalling 35 students. The validity test results were 87% from media experts, 94% from material experts, 89% from language experts, and 91% from teachers. The results of the product effectiveness test via the T-Test (Paired Sample T Test) show a significance value of 0.000. Based on the test criteria, the value is ? 0.05. Based on decision-making for the research hypothesis in the Paired Sample T-Test, Ha is accepted, and H0 is rejected. So, it can be seen that there are differences in student learning outcomes before using learning videos and after using learning videos. The media in the form of learning videos on the Periodization of Class VII Social Sciences pre-literacy period is declared valid according to media experts, material experts, language experts and teachers and is effective for improving student learning outcomes.
