This study aims to determine whether there is an influence of the problem-based learning model (PBL) with a STEM approach on the mathematical problem solving ability of grade VIII students of SMP Negeri 17 Medan. This research was conducted at SMP N 17 Medan T.A 2023/2024. The research method used is a quasi-experimental method. The sample of this study consisted of two classes, namely class VIII-3 as an experimental class taught with a PBL model with a STEM approach and class VIII-4 as a control class taught with conventional models. Based on descriptive statistics and categorization of research results, it was found that the mathematical problem solving ability of experimental class students was 67,74% of students in the high category, 32.26% of other students in the medium category, and no students in the low category. Meanwhile, in the control class, 15,63% of students were in the high level of problem solving ability, 53,13% were in the medium level and 31,24% of students were in the category low category. Thus it can be seen that the mathematical problem solving ability of grade students taught with PBL with a STEM approach is better than conventional learning models. Furthermore, with inferential statistical analysis for the t test, calculated t value = 2,42 and ttable = 1,999623, thus t calculated > t table means that the problem-solving ability of students taught with PBL with a STEM approach is not the same as students who use the learning  conventional model. With further analysis, Fcalculated = 5,6847 and F table = 3,998494482, then  calculated F > F table so it can be concluded that problem-based learning models with a STEM approach have a significant effect on students' mathematical problem solving abilities.

This research aims: (1) the mathematical communication abilities of students using the think-talk-write (TTW) cooperative learning model are higher than the mathematical communication abilities of students using conventional learning models in class VIII SMP Negeri 19 Medan, (2) the process of completing answers is created by students in solving problems in the think-talk-write (TTW) cooperative learning model and conventional learning models. This type of research is quantitative research with a Quasi Experimental method. This research was conducted at SMP Negeri 19 Medan. The sampling technique in this research used the Purposive Sampling technique, namely class VIII-5 as a class taught using the think-talk-write type cooperative learning model and class VIII-6 as a class taught with a conventional learning model. The data collection instruments were an observation sheet and a test sheet for students' mathematical communication skills in the form of 4 essay questions. Data analysis in this study used a t-Test with the Independent sample t-Test technique with the help of the SPSS 22 program. The results of the research showed that the average score for the class taught using the think-talk-write cooperative learning model was 80.1 and the class taught with a conventional learning model of 74.6. Hypothesis testing was carried out using the t-test, from the calculation results it was obtained that tcount was 2.501 and ttable 1.67469, the significance level was 0.016<0.05, then H0 was rejected and Ha was accepted, so it was concluded that students' mathematical communication skills used the cooperative learning model type. think-talk-write is higher than students' mathematical communication skills using conventional learning models. Based on the analysis of the process of students' answers to the mathematical communication skills test, students who received think-talk-write cooperative learning were better than students who received conventional learning.

The purpose of this study is to ascertain how efforts are made and enhance students' capacity for problem-solving following the application of the lesson study-based scientific approach and problem-based learning model. 38 students from SMP Negeri 4 Tebing Tinggi's VIII–5 class during the 2022–2023 academic year served as the research subjects. Classroom Action Research (PTK), which is this kind of research, is divided into two cycles. In pre-action, students take an initial test, and at the conclusion of each cycle, they take an exam on their problem-solving skills. The research findings are as follows: (1) If the teacher masters and effectively applies the PBL model and scientific approach based on lesson study, students' mathematical problem solving abilities can be improved, (2) Application of the PBL model can increase student learning completeness by 63.16% from 23.68% at the end of cycle I to 86.84% at the end of cycle II. (3) Students' mathematical problem solving abilities can be improved by 34.37% from 47.47% at the end of cycle I to 82.04% at the end of cycle II.

This research aims to determine the application of the Cooperative Integrated Reading and Composition (CIRC) model in learning to write personal letters for class VII students at SMPN 1 Gunungwungkal Pati. Based on the results of observations, there is a problem with class VII students at SMPN 1 Gunungwungkal Pati, namely that students still have difficulty using the right words and writing a message on personal letter writing material, because the learning model used by the teacher is not appropriate. This research uses mixed methods. Data collection was carried out using test and non-test techniques. The test technique is in the form of working on personal letter writing test questions, and the non-test technique is in the form of observation and questionnaires. Based on the research results, before implementing the Cooperative Integrated Reading and Composition (CIRC) model in learning to write personal letters, teachers still used Discovery Based Learning techniques for the learning process of writing personal letters and only used Indonesian language textbooks as learning support materials. The application of the Cooperative Integrated Reading and Composition (CIRC) model has proven that students are more active during learning. The (CIRC) model also makes students more enthusiastic and makes it easier for students to understand the material for writing personal letters.  

In the era of revolution 4.0, education does not only require intellectual abilities, but critical thinking, creative, communicative and collaboration skills. The problem with Civics learning is that it still prioritizes cognitive aspects, it has not been able to realize the goal of creating critical and responsible students. There needs to be innovation in Civics learning that combines problem-based learning models through games and is integrated with the use of technology in elementary schools. This research aims to find out the influence of problem based learning implemented through the QR code-assisted treasure hunt game on Civics learning. The research method used is descriptive qualitative. The analysis technique used is an interactive analysis model consisting of data reduction, data presentation, and drawing conclusions or verification. The results of data analysis are presented in the form of descriptions supported by observations, interviews and literature studies. The results of the analysis and discussion can be concluded that critical thinking skills emerge in Civics learning using the PBL treasure hunt and QR code models. Critical thinking skills are demonstrated by the emergence of the following indicators: providing simple explanations, building basic skills, concluding, making further explanations, strategies and tactics. It is hoped that the results of this study can become a reference, especially in the field of education, to create a superior and characterful next generation.
