The purpose of the study is to determine the influence of the problem-based learning model on the mathematics learning outcomes of grade VII students on statistical materials. The research method used in this study is Pre-Experimental Design with a One-Group Pretest-Posttest design model. The research was carried out by direct observation in the classroom by giving a pretest at the beginning of learning to 30 grade VII students and giving a posttest at the end of learning. To find out the difference in student learning outcomes, the researcher used a problem-based learning model. At the beginning of learning, the average score from the pretest was 59.80. After the application of the problem-based learning model and given a posttest, the average score on the posttest was 77.03. The data collection methods used were tests, documentation, and observation. Meanwhile, to analyze the data using the pretest and posttest statistical description test, normality test and Paired sample T-Test using SPSS. Test the normality of the data to find out if the data is normally distributed. It is known from the normality test, the significance value in the pretest value is 0.200 and the significance value in the posttest score is 0.069 greater than 0.05 which shows that the residual value states that the data is normally distributed. Meanwhile, the paired sample t-test value with a Sig. (2-tailed) value of 0.000, meaning that the paired sample t-test value is less than 0.05 or 0.000 < 0.05. Therefore, it can be concluded that there is a difference in the mathematics learning outcomes of grade VII students in the statistics material at SMP Mutiara Islami Plus before and after the implementation of the problem-based learning model.

This study aims to determine students' critical thinking skills in solving Higher Order Thinking Skill (HOTS) problems on two-variable linear equation system material. This research is a qualitative descriptive research. The subjects of this study were 15 students of grade X MIPA SMA Islam Hisada Pontianak. Descriptive qualitative is the method used in this study and data analysis techniques using models from Miles & Huberman. The instrument used is a HOTS question of 3 questions. The results showed that students with low category abilities did not meet all four indicators of critical thinking skills. Students with moderate category ability can pass three indicators of critical thinking ability well, while students with high category ability can go through all indicators of critical thinking ability properly and correctly.

This study aims to prove the presence or absence of the Dragon Ball Learning Model on the cognitive learning outcomes of grade VII mathematics on flat building material in MTs Miftahul Huda Bogorejo Sedan Rembang for the 2021/2022 academic year. This type of research is quantitative using post-test only control groups. As for the formulation of the problem in this study, which is better between the Dragon Ball learning model and direct learning of the cognitive learning outcomes of grade VII Mathematics on Flat Build at MTs Miftahul Huda, Bogorejo, Sedan Rembang, Academic Year 2021/2022. The data collection method uses a multiple-choice question test of 10 points. The data collection obtained, the calculation results obtained the average value of the experimental class was 73.18 while the average value of the control class was 41.82. Based on the results of data analysis, it was found that the result of the sig value was 0.05, then H_0 rejected and H_1 accepted. So it can be concluded that the learning carried out using the Dragon Ball learning model results are higher than using the direct learning model, which means that the Dragon Ball learning model is better than the direct learning model.
