Abstract

Social arithmetic is a useful topic for mastering numeracy skills that are useful in solving real-world problems. However, students' difficulties in solving social arithmetic problems are still found. In addition, the limitations of available digital learning resources are also an obstacle for some teachers. This article aims to describe the process and results of developing digital mathematics teaching materials with the Book Creator applications to promotes students' understanding of concepts in social arithmetic. The development of this teaching material is based on the ADDIE model with the following stages: analysis, design, development, implementation, and evaluation. Based on the conceptual understanding test on 6 subjects with various mathematical abilities, the average achievement result was 89%. The advantage of this teaching material is that it contains contextual problems that are in accordance with real-life situations, but on the other hand it is still necessary to develop more open-ended questions. This teaching material also contains questions for self-reflection to facilitate self-regulation in learning. For further development, teaching materials also need to be improved in terms of appearance, scope of lesson topics, and practicality in terms of collecting student written answer documents.

Abstract

Inquisitiveness is a critical thinking disposition that is important in the inquiry process because it relates to the tendency to ask questions. However, studies on inquisitiveness in the domain of mathematics learning are still limited. Several previous studies have only explained inquisitiveness based on general attitudes without involving the context of the field of mathematics. This study aims to describe the inquisitiveness of mathematics prospective teacher students which is showed in asking questions. This research is a qualitative research with prospective teacher students at Universitas Pesantren Tinggi Darul Ulum as the participants. The research data was collected through tests, observations, and interviews. The results of the study show that the tendency of prospective mathematics teacher students to ask effective questions when responding to information in mathematical problems is still low. Prospective teachers cannot always ask questions even if they do not understand the rationale behind a statement. Another finding from this study is that even though prospective teachers can ask questions in discussion, their questions cannot meet the inquisitiveness criteria because they are less successful in developing in-depth understanding.

Abstract

Graphs are essential representations in mathematics, but many students only focus on procedural rules when sketching graphs of equations. This study aims to describe the errors and obstacles experienced by students in drawing graphics of equations. The research method uses a qualitative approach by collecting data through tests and interviews. The research results show that students' mistakes in drawing graphs can be caused by dependence on procedural knowledge in plotting points without conceptual understanding. Students who make mistakes do not understand points as multiplicative objects, lack covariational reasoning, need help understanding the concept of complex numbers, and show reflective thinking in completing assignments. This research implies that teachers must consider the students' difficulties and mistakes to avoid becoming didactic learning obstacles. In studying plotting point procedures, students' knowledge must include understanding concepts related to graphs, such as the meaning of points and graph concavity, graph shifts, and the relationship between the discriminant of a quadratic equation and its graph.

Abstract

Argumen matematis siswa tingkat dasar hingga sekolah menengah sering sulit dikaitkan dengan pembuktian matematis formal. Model Argumen Toulmin menawarkan suatu pendekatan untuk menganalisis argumen yang sangat berbeda dengan pendekatan logika formal. Studi ini bertujuan untuk mendeskripsikan struktur argumentasi siswa kelas VIIIB MTsN 1 Kediri ketika menyelesaikan masalah kovariasi berdasarkan teori argumentasi Toulmin. Hasil penelitian ini mengungkapkan bahwa subjek belum memiliki struktur argumen yang lengkap. Secara umum subjek membangun argumen secara induktif. Peran “backing” menjadi esensial ketika argumen subjek didukung oleh contoh-contoh kasus yang mengantarkan pada suatu kesimpulan, sementara “qualifier” dan “rebuttal” tidak muncul pada struktur argumen mereka.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan aktivitas pembelajaran dan refleksi mahasiswa terhadap meta-isu dalam matakuliah Sejarah Matematika dengan tugas proyek di Program Studi Matematika Unipdu Jombang. Pendekatan kualitatif digunakan dalam penelitian ini. Subjek penelitian ini adalah mahasiswa semester  ke-3 Tahun Akademik 2014/2015 yang sedang mengikuti matakuliah sejarah matematika di Program Studi Matematika Unipdu Jombang. Pengambilan data dilakukan melalui observasi, dokumentasi, dan wawancara. Aktivitas dalam pembelajaran Sejarah Matematika dengan tugas proyek pada mahasiswa Program Studi S1 Matematika Unipdu Jombang yaitu meliputi mengkaji literatur, menulis hasil kajian literatur dan mempresentasikannya, memilih topik proyek, menghasilkan produk, dan mempresentasikan produk. Hambatan pada pembelajaran yaitu kurang optimalnya aktivitas mengkaji literatur. Hasil penelitian menunjukkan bahwa berdasarkan refleksi terhadap meta-isu, tingkat interdisipliner mahasiswa yaitu pada crossdisciplinarity merujuk pada taksonomi Jantsch.

Abstract

Background: Many students have difficulty distinguishing between direct and inverse proportion problems. This difficulty can cause interference during problem solving. One form of interference is proactive interference, which occurs when previously learned information disrupts the understanding of new information. In proportion problems, students’ prior knowledge of direct proportion often influences how they approach inverse proportion tasks, leading them to apply incorrect strategies. Aim: This study aims to describe the process of proactive interference experienced by students when solving proportion problems using the Mindsponge framework. Method: This study used a qualitative descriptive approach. The participants were 32 eighth-grade students from Junior High School 3 Malang. The selected subjects were students who could correctly solve direct proportion problems but applied the direct proportion concept when solving inverse proportion problems. Data were collected through proportion problem tests and interviews. Students’ written work was analyzed using indicators from the Mindsponge framework, and the findings were triangulated by comparing students’ work with interview results. Results: The results show that proactive interference occurred at three stages of the Mindsponge framework: environmental, filtering, and mindset. At the environmental stage, students made errors in observing and understanding the problem. In the filtering stage, students incorrectly determined the quantitative relationship between variables. At the mindset stage, students relied on their prior knowledge of direct proportion and frequently used the cross-multiplication strategy. Conclusion: The study indicates that proactive interference occurs when previously learned concepts dominate students’ thinking processes. The Mindsponge framework helps explain how prior knowledge influences the way students interpret and apply new information when solving proportion problems.
