This study aims to describe students' mathematical communication skills in terms of their intrapersonal intelligence. This type of research used in this study is a descriptive study using a qualitative approach with as many as 5 people using purposive sampling techniques. In order to obtain the data needed in this study, data collection took the form of tests of mathematical communication skills with algebraic form material, and intrapersonal intelligence questionnaires. The data obtained in the form of data from test results and questionnaires, then the data are analyzed and concluded. Overall the results of tests that were followed by 5 students had mixed results. Furthermore, research subjects were taken to take a written test of mathematical communication skills. Each subject was taken 3 out of 5 students. Based on the results of the study it can be concluded that research subjects who have high intrapersonal intelligence will look superior in their mathematical communication skills. This is because they prefer to interpret understanding by managing and controlling themselves. As for students with abilities that are categorized as low and moderate they can also be intelligent in other types of intelligence and other factors that influence it. Therefore, teachers must pay more attention to each intelligence possessed by students and must apply appropriate learning methods.

This study aimed to identify and analyze self-regulation that mediates the influence of resilience and family environment on students' mathematics learning outcomes. This descriptive research uses the method of explanatory survey with a quantitative approach. The variables in this study were mathematics learning outcomes (Y), resilience (X1), family environment (X2), and self-regulation (Z). Learning outcomes are the dependent variable (endogenous variable). At the same time, resilience and family environment are independent variables (exogenous variable), and self-regulation is a mediating variable (intervening variable) with questionnaires and observations to collect data. This study's population was all class VII students at State Middle School in Serang City, while the sample was randomly selected from as many as 332 students. The collected data is then analyzed using a structural equation model. The results of this study indicate that (i) there is a significant effect of resilience on mathematics learning outcomes, (ii) there is a significant effect of the family environment on student learning outcomes, (iii) there is a significant effect of self-regulation ability on mathematics learning outcomes (iv) there is a significant effect of resilience on students' abilities self-regulation (v) there is a significant influence of the family environment on self-regulation abilities (vi) there is a significant effect of resilience on student learning outcomes through self-regulation abilities (vii) there is a significant influence of the family environment on student learning outcomes through self-regulation abilities (viii) there is a significant influence resilience, family environment, and ability to self-regulate on mathematics learning outcomes.

This study aimed to determine the effectiveness of using the STEM approach in learning direct electric circuits to achieve high school students' scientific and practical thinking skills. This research is a quasi-experimental method. This study used two class groups, namely the experimental class and the control class, with the experimental class being the class group that received the STEM learning treatment. In contrast, the control class was the class group that only received the immediate learning model treatment. The research design uses a non-equivalent control group design. The research was carried out in the even semester of 2021-2022 and the place of this research was one of the schools in Serang City, Banten province. The sample consisted of two classes; one class was given the learning treatment with the STEM approach, which served as the experimental class, and the other class received no therapy and functioned as the control class. Each course has 40 students, including 20 male and 20 female students. The average age of students is 17 years. The instrument used in this study was in the form of 10 essay questions. This question covered electric current circuit material with indicators of scientific thinking ability and practice. The instrument used in this study was in the form of 10 essay questions. This question covered electric current circuit material with indicators of scientific thinking ability and practice. The data obtained after the research will be analyzed using N-Gain data analysis. The N-gain result in the experimental class was 0.67, while the control class was 0.46. The N-Gain results of the two types show the same category, namely the good category. However, the N-gain results from the experimental class show a value greater than 21% than the control class. These results prove that learning electric circuits using STEM is more effective than learning directly. The implications of this research are 1) It can foster an understanding of the relationship between the concept of electric circuits with practical skills in assembling electric current circuits, 2) Arouse students' curiosity and activate creative imagination and critical thinking, 3) Help students to understand and experiment with the scientific process.

This study aimed to determine the higher-order thinking skills of pre-service teachers through STEM-PjBL Model. The research method used was a quasi-experimental with one group pretest-posttest design. The N-Gain results mention the N-gain in both experimental and control classes that the physics learning process through the STEM-PjBL Model is 21% higher in improving higher-order thinking skills than Direct Learning. Improvement of students' ability to solve HOTS categorical questions in the experimental group taught by applying STEM-PjBL Model scored N-Gain 75% or 0.75, which increases the high category. In comparison, the control group led by applying the Direct Learning model achieved 54% or 0.54, meaning a moderate increase in categories. The results showed that learning using STEM-PjBL Model could improve higher-order thinking skills more than Direct Instruction Learning. The implications of this research include: gaining new knowledge that can be used as a pre-service teacher’, adding insight regarding STEM-PjBL Model that can be used to grow students' science process skills, assisting schools in improving the quality of students, and the quality of the physics learning process in schools.

Tujuan penelitian ini adalah menganalisis kemampuan pemahaman konsep matematis siswa sekolah menengah pertama yang ditinjau dari gaya kognitif Field Independent (FI), Field Intermediate (FID), dan Field Dependent (FD). Subjek penelitian ini adalah adalah siswa MtsN Pandeglang 1 kelas IX-C berjumlahkan 20 siswa yang dikelompokkan berdasarkan gaya kognitif yang dimiliki oleh setiap siswa, setiap kelompok gaya kogitif diambil perwakilan 2 siswa dengan menggunakan metode purposive sampling untuk diukur kemampuan pemahaman konsep matematisnya. Kemampuan pemahaman konsep matematis pada penelitian ini memiliki tujuh indikator. Berdasarkan hasil penelitian ini kemampuan pemahaman konsep matematis siswa memiliki kesamaan dan perbedaan. Siswa dengan kelompok gaya kognitif Field Independent (FI) memiliki kesamaan kemampuan pemahaman konsep matematis, yaitu mereka mampu mencapai semua indikator yang terdapat pada kemampuan pemahaman konsep matematis. Siswa dengan kelompok gaya kognitif Field Intermediate (FID) memiliki perbedaan kemampuan pemahaman konsep matematis, salah satu siswa dapat mencapai semua indikator dan siswa lainnya hanya memenuhi beberapa indikator kemampuan pemahaman konsep matematis. Hal ini menunjukkan bahwa siswa yang termasuk dalam kelompol gaya kognitif yang sama belum tentu memiliki kemampuan pemahaman konsep matematis yang sama. Siswa dengan kelompok gaya kognitif Field Dependent (FD) hanya sedikit indikator yang mampu dicapai oleh siswa dalam indikator kemampuan pemahaman konsep matematis.
