This study aims to determine the effect of using the Search, Solve, Create, and Share (SSCS) learning model assisted by ethnoscience videos on students' cognitive learning outcomes in the subject of IPAS. The type of research used is quantitative with experimental methods. The research design used is quasi experimental design with the form of nonequivalent control group design. Sample determination is saturated sampling. The population in this study were grade V students of SDN 4 Selakau totaling 49. The results showed that: (1) There is a significant difference in students' cognitive learning outcomes between classes given the SSCS learning model assisted by ethnoscience videos and classes given conventional learning, the results show that tcount = 10,98 > ttable = 2,01. (2) The SSCS learning model assisted by ethnoscience videos has a high effect on students' cognitive learning outcomes, the results of the effect size in this study are 0,81 in the high category. (3) There is an increase in students' cognitive learning outcomes after being given the SSCS learning model assisted by ethnoscience videos as indicated by the results of the N-gain = 0,72 in the high category. There is a very positive response to the SSCS learning model assisted by ethnoscience videos, the results of calculating the percentage of student responses show an average of 88%. Thus it can be concluded that the SSCS learning model assisted by ethnoscience videos can affect students' cognitive learning outcomes.
