HOTS - based scientific learning to increase the comprehension concept and science students skill

This research aims to know the effectiveness of HOTS based scientific learning models to increase the comprehension concept and science students skill. The method was quasi-experiment with Pretest-Posttest Control Group Design. The type of data obtained in this study is quantitative data. Data collection techniques in this study were used observation, student questionnaires, and student evaluation tests. Data analysis using the homogeneity, normality, and t-test to test the effectiveness of the model. Based on the output table ″independent samples test, it is known that the sig. (2-tailed) knowledge value is 0.224 and the sig (2-tailed) skill value is 0.507. Because the sig value is 0.224 and 0.507> 0.05, according to the basis of decision making in the independent sample t-test, it can be concluded that Ho is accepted and Ha is rejected, which means that there is a difference between the average knowledge and skill values of SDN Sayung 3 and 4. Based on the research results obtained, it is known that the use of hots-based scientific learning models is proven to be effective in improving thecomprehension concept and science students skill. In addition to testing the effectiveness of the model, researchers also observed student activities to strengthen research results. Besides, data analysis of student and teacher responses showed the highest positive results.
