Mathematical communication skills are essential for students learning mathematics, but many have low mathematical communication skills. This quasi-experimental design research aims to determine the influence of the brainstorming learning model and linguistic intelligence on mathematical communication abilities and the interaction between the brainstorming learning model and linguistic intelligence on mathematical communication abilities. This research involved class VIII students at Ma'arif 10 Bangunrejo Junior High School for the 2023/2024 academic year with a research sample of 55 students (27 class VIII A students as the experimental class and 28 class VIII B students as the control class). Mathematical communication skills data was obtained using an essay test, while linguistic intelligence data was obtained using a questionnaire. The collected data was analyzed using the Two Way Anava statistical test with a significance level of 0.05, where before testing, it was found that the data was normally distributed and homogeneous. The results of this research inform that the brainstorming learning model affects mathematical communication skills, while linguistic intelligence does not affect mathematical communication skills. Furthermore, there is no interaction between the brainstorming learning model and linguistic intelligence on mathematical communication abilities.

This research explores the impact of Guided Inquiry Learning-oriented learning with a scientific approach on understanding mathematical concepts of PGMI UIN Fatmawati Sukarno Bengkulu students. The research design uses an experimental method with an experimental group and a control group. The results of the analysis show that students who were taught using Guided Inquiry Learning-oriented learning experienced a significant increase in understanding mathematical concepts compared to learning without a Guided Inquiry Learning orientation, even though both used a scientific approach. A significant value of less than 0.05 in a statistical test indicates that the difference can be considered statistically significant. However, the results of further analysis showed that there was no significant difference in increasing understanding of mathematical concepts between classes that used the Scientific Approach and the control group in two particular classes (Class=2 and Class=3). A P-value greater than 0.05 in statistical analysis indicates that the results are not statistically significant. Thus, although there was a significant increase in understanding of mathematical concepts in the group that implemented Guided Inquiry Learning-oriented learning, this research also showed that there was no significant difference in this increase between this group and the control group in two particular classes. These results provide further understanding about the effectiveness of certain learning methods in improving students' understanding of mathematical concepts.

The Kampus Mengajar Program is a government policy aimed at students to provide innovations to problems in partner schools in the teaching and learning process. The problem is that in learning, no attention is paid to students' problem-solving skills when working on story problems. This study aims to describe and analyze the problem-solving skills of story problems on beam volume material for grade IV students in one of the Kampus Mengajar partner schools in Pemalang Regency, SD N 3 Kedungbanjar. The qualitative approach is descriptive, involving 28 students and focusing on three students representing high, medium, and low abilities. Data collection used tests, documentation, and interviews. The instruments used were two problem-solving test questions, interview guidelines, and a rubric for assessing problem-solving skills based on the stages of the Polya Model (understanding the problem, planning a solution, implementing a solution plan, and checking back). The results showed that students with low average test scores still had difficulties in the stages of Polya's Model. Many students did not use all four stages of problem-solving entirely and correctly. Students had difficulty at the recheck stage, with the percentage of students who went through the stage only amounting to 18.75%. Based on the high, medium, and low category subjects, it shows that (1) High-skills subjects can complete all stages of Polya Model problem-solving. (2) Moderate skills subjects have not been able to complete all stages of Polya Model problem-solving by skipping the checking backstage. (3) Low-skills subjects were only able to go through the stages of making and implementing a solution plan by skipping the stages of understanding the problem and checking back. Development recommendations are expected to be needed to improve the results and process of problem-solving skills.
