This study aims to (1) determine the effect of the application of guided inquiry model based on video learning on improving student learning outcomes. (2) find out whether students' chemistry learning outcomes using instructional video media are higher than students' chemistry learning outcomes taught using powerpoint media. This research was conducted in November-December 2021 at SMA N 1 Sunggal involving experimental class I and experimental class II. The two classes were given different treatment, the experimental class I was given learning using a guided inquiry model and learning videos, the experimental class II was given learning using a guided inquiry model and powerpoint. This research is a quasi-experimental research design with the Nonequivalent control group design model. From the results of the study, the average pretest value of the experimental class I was 43.47 and the average value of the experimental class II was 43.19. After being given treatment, the two classes were then given a posttest to determine learning outcomes, the average posttest score for the experimental class I was 83.33 and the experimental class II was 79.16. The results showed that both classes experienced an increase in learning outcomes, the experimental class I experienced an increase in the value of 39.86 and the experimental class II by 35.19. The N-Gain data for the experimental class I was 71% and the experimental class II was 64%. It can be concluded that the guided inquiry model and learning video media can have an influence on student learning outcomes in the form of increasing learning outcomes.

The research aims to determine the effect of implementing problem-based e-Modules on student motivation and learning outcomes in colloid system material in class XI SMA Negeri 9 Medan. This research method is descriptive quantitative with taking samples from the population by random sampling as many as 60 students as samples (30 students in class XI-2 as experiments and 30 students in class XI-1 as controls). Data was collected through tests and questionnaires, then analyzed using SPSS 24 for Windows with a one-party t-test. The results of the analysis show that students' chemistry learning motivation increased significantly with the implementation of the e-Module, with the average score of the experimental class (71.33%) being higher than the control class (49.00%). This is supported by the results of the one-party t-test which shows a significance value of 0.001 < 0.05. Apart from that, there is a significant influence on students' chemistry learning outcomes, with the experimental class post-test score (79.67) being higher than the control class (74.5) and the one-tailed t-test significance value of 0.031 < 0.05 . Research also shows a positive correlation between motivation and student learning outcomes with a sig value of 0.026 < 0.05, confirming that the application of problem-based e-Modules contributes to improving student chemistry learning outcomes in colloidal systems material.

The purpose of this study is to ascertain how problem-based online modules affect students' learning results in acid-base chemistry and to determine the correlation of e-modules with motivation and student learning in acid-base materials at SMA Negeri 11 Medan. This research took a sample consisting of 1 group, namely the experimental group in class XI MIPA 6. Tests for normality, homogeneity, hypothesis, and correlation are used in data gathering procedures. After testing, the prerequisite is that the experimental data is normally distributed, for the homogeneous test the experimental class is homogeneous. To test the hypothesis, test is used One Sample T Test, and to test the correlation test is used Product Moment then the data results are obtained for the value hypothesis tcount > ttable, then Ha is accepted and Ho is rejected with the pret-test value in the experimental class, namely X and the post-test value in the experimental class, namely X, correlation test rcount > rtable, then Ha is accepted and Ho is rejected. The findings indicated that learning results were different before and after receiving media therapy in the form of problem-based e-modules. Additionally, the relationship between students' motivation and the chemistry learning results in problem-based e-modules.
