As time goes by, many innovative approaches, strategies, methods, and learning techniques have been created to make students more interested in learning mathematics. However, in reality, not all teachers can apply various innovative student-centered learning approaches in mathematics learning. This research took place at a high school in the city of Bandung to describe how mathematics learning using the expository method is implemented in that school. This research is case study research, with data collected using observation and interview techniques with both teachers and students. Based on the results of observations, it is known that learning is carried out in three stages, namely preliminary, core, and closing activities. In the core learning activities, the teacher chooses to use the expository method which collaborates with cooperative learning and constructivist learning, although in this case, expository learning is more dominant. Learning mathematics using the expository method is seen as more effective for use in learning because it suits the character of the students and the material being taught.

The purpose of this study is to determine if the STEAM-based Project Based Learning learning model improves students' mathematics learning outcomes on the topic of social arithmetic in comparison to conventional learning models. Class VII A, who utilized the Conventional model, and Class VII C, who utilized the STEAM-based Project Based Learning learning model, served as the research subjects. Pretest Posttest Experiment Group Design is the research design for this quasi-experimental study. The two classes with 20 and 21 students, respectively, that comprised the research sample were VII A and VII C. Both classes were normal and homogeneous. A t-test is used for the data analysis test, and values are rejected before being accepted. As a result, students' learning outcomes have improved when employing the STEAM-based Project Based Learning learning model.

The purpose of this research is to develop a Students' Working Sheet (LKPD) based on mathematical reasoning for 7th-grade students of UPTD SPF Junior High School 3 Bondowoso. In this study, Thiagarajan's development model (1974) is used, which consists of four stages: Define, Design, Develop, and Disseminate. However, the development of mind mapping-based LKPD is only limited to 3D. The initial observation shows that students have different levels of mathematical reasoning ability. The result of the study includes the validity, practicality, efficiency, and effectiveness of the LKPD. After being validated by two validators, the validity of LKPD is assessed, with 3,25 as the average score which indicates a good level of validity. The practicality of the LKPD was assessed by the teacher's questionnaire, which received 81,25% as the average score, which shows that the LKPD can be considered practical. The efficiency of the LKPD was assessed by the student’s questionnaire, which received 86,27%, which shows that the LKPD can be considered as efficient.

Learning media that is less interesting can trigger bad responses given by students during learning. One of the interesting learning media for students is through games. This research uses descriptive quantitative methods to describe the level of student satisfaction after participating in learning using problem-based learning-based truth or dare games. The data collection technique in this research is in the form of a questionnaire containing closed statements and includes 3 indicators using a Likert scale. This research was carried out at SMPN 2 Sumobito with research subjects in class VII-C even semester of 2023/2024. The results obtained were that the cognitive indicators produced a percentage value of 79% (very strong), affective 79% (very strong), and conative 81% (very strong). The overall response value percentage is 80% in the very strong category.

Representasi Mahasiswa dalam Memecahkan Masalah Pembuktian Geometri

Problem-solving skills are related to other abilities, such as conceptual understanding, application of concepts, representation, and communication of ideas. When solving problems, we must understand the problem and can do this by providing an appropriate representation of the problem. Accurate representation offers a greater opportunity to achieve the desired solution. Therefore, research on students' representations in problem-solving is essential to provide an overview of how students form representations when solving geometric problems. This study uses a qualitative approach with a descriptive method. The research subjects are three students from the mathematics education program at Unipdu with high, medium, and low abilities. The results show that the low-ability subject uses pictorial representation and cannot solve the problem. The medium-ability subject uses schematic and symbolic representations but with less perfection in usage, so even though the solution found is correct, it is presented in a less structured manner. Meanwhile, the high-ability subject uses schematic and symbolic representations and finds solutions in a more structured way.

Analisis Proses Berpikir Kreatif Matematis Siswa SMP Kelas VII Pada Materi Bangun Datar

Yugi Hilmi, Fithri Sri Mulyani — Tue, 02 Jul 2024 00:00:00 +0700

The creative thinking process is a step taken to produce solutions to problem solving. This research is descriptive qualitative and the aim of the research is to analyze the creative thinking process of junior high school students based on Wallas Theory. The research subjects were 28 class VII students at SMPN 1 Mangunreja. Data collection techniques include creative thinking tests, conducting interviews and documentation. The results of the research are 1) students in the high creative thinking category are able to reach the stages of preparation, incubation, illumination and verification; 2) students in the creative thinking category are able to reach the preparation and incubation stages, while the illumination and verification stages still need to be developed; 3) students in the low creative thinking category are only able to reach the preparation stage so that the other three stages need to be developed.
