Fitriana Eka Chandra — 2024-07-02

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.

Representasi Mahasiswa dalam Memecahkan Masalah Pembuktian Geometri

Dian Novita Rohmatin — 2024-07-02

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.

Misinterpretasi Konteks Dunia Nyata dalam Memecahkan Masalah Literasi Matematis

Chusnul Galatea — 2024-07-11

This study employs a qualitative approach to describe junior high school students' interpretative abilities in solving mathematical literacy problems. The sampling technique used in this research is purposive sampling. Credibility testing is conducted through source triangulation, which is used to test the credibility of data by cross-checking data obtained from several sources. The results of this study indicate that both subjects, S1 and S2, utilize real-world contexts to check the reasonableness of their answers, provide arguments, and set solution boundaries. However, the use of real-world contexts in interpreting mathematical literacy problems is insufficient to produce correct answers. Misinterpretation of the real-world context by both subjects leads to an inability to appropriately link mathematical concepts with their real-world applications. This study highlights that, in addition to using real-world contexts, a good understanding of mathematical concepts is essential for correctly solving mathematical literacy problems.
