This study aims to determine the effect of the Snowball Throwing learning model assisted by simple experiments on students’ achievement motivation in colloid material. The independent variable in this study is the Snowball Throwing learning model assisted by simple experiments, while the dependent variable is students’ achievement motivation. The type of research used is a quasi-experiment with a post-test only control group design. The population of the study consisted of all 38 students of class XI MIA at SMA Negeri 16 Samarinda, all of whom were taken as samples using a saturated sampling technique. The research instruments were an achievement motivation questionnaire and an observation sheet. Data were analyzed using normality tests, homogeneity tests, and t-tests at a significance level of 0.05. The results showed that the average score of students’ achievement motivation in the experimental class was higher, at 83.68%, compared to the control class, which was 75.53%. Therefore, it can be concluded that the application of the Snowball Throwing learning model assisted by simple experiments has a positive and significant effect on students’ achievement motivation in colloid material at SMA Negeri 16 Samarinda.  

The aim of this research is to determine the difference in learning motivation of students who are taught using the snowball throwing learning model and those who are not taught using the Snowball Throwing learning model at SMP Negeri 1 Sipoholon for the 2023/2024 academic year. The method used in this research is a quantitative research method with a pre-experimental design research type in the form of a one-group-pretest-posttest design. The population was all class VIII students at SMP Negeri 1 Sipoholon, totaling 188 people and the researchers determined a sample of 32 people using a purposive sampling technique. Data was collected using a positive closed questionnaire with 27 items. Research data for the questionnaire was analyzed using the related sample formula. From the calculation results, the tcount value = -29.052<ttable 2.039 with a 2-party test (α/2=0.05/2=0.025)= 2.039. The tcount value is in the curve area of ​​rejection of H0 and acceptance of H1. Thus, it can be concluded that the research hypothesis is accepted, namely that there is a difference in the learning motivation of students who are taught using the snowball throwing learning model and those who are not taught using the Snowball Throwing learning model at SMP Negeri 1 Sipoholon for the 2023/2024 academic year. The difference in learning motivation for Christian Religious Education and Characteristics of Class VIII Students at SMP Negeri 1 Sipoholon for the 2023/2024 Academic Year can be seen from the average scores of X1 = 77.0 and X2 = 88.3.

This research is apreliminary research that contains efforts to implement the snowball throwing learning model at the elementary level, especially in grade 4. This study also aims to determine student responses to the application of the snowball throwing learning model at the elementary school level. This study used a research design with the "One Shot Case Study" design, namely research conducted by giving certain treatment to research subjects, in this case the snowball throwing learning model. The data obtained were analyzed using research methods for students. In this study the authors used a data collection technique in the form of a questionnaire technique. The questionnaire used in this research is a student learning motivation questionnaire. The results of this study indicate that students' responses to learning using the snowball throwing model received a positive response with a percentage of 88.43%.
