Abstract

This study aims to analyze the planning process for solving contextual problems. The research subjects consisted of three students of class IX SMP. The research used is a qualitative research with a descriptive approach. The instrument used is a task-based interview. The data is analyzed according to the indicators of problem solving at the planning stage, namely identifying information, selecting old knowledge that can be used in problem solving, mentioning theorems related to the problem, making plans. The results showed that the first student was able to identify the information needed but the student did not submit it in writing. The first student solved the problem using the volume formula, but the student experienced a conceptual error in the middle of completion. The second student is able to identify and write down the required information, the second student uses mathematical formulas and estimates to determine the amount of wrapping paper needed. The third student is able to understand which information can be used and which information is redundant. At first the third student used the formula to solve the problem, but in the middle of the completion the student changed the plan by applying real life/context applications. Based on the results of research conducted that two students out of three students when solving problems did not pay attention to the context.

Abstract: Students' Conjectures on Open Classical Analogy Problem: Expanding or Narrowing?. Objectives: This study aims to describe students' mathematical conjecture in the context of open classical analogy problem. Methods: This descriptive research describes students' conjectural profiles using open classical analogies. Data were collected from the responses of 68 students. Data analyzed using constructor example, process, and quality of the conjecture. Findings: Results show that the example of constructing the conjecture has not paid attention to all possible cases, while the process of the conjecture used by students was from simple to more expanding or narrowing. Some of the proposed conjecture quality does not include the necessary constraints, and some include unnecessary limitations. Students can add to statements that sharpen the conjecture proposed previously. Conclusion: The results of this study indicate that in the construction of conjectures in the context of an open classical analogy, students involve their critical thinking skills. Keywords: conjecture, example, open classical analogy, process, quality of conjecture.DOI: http://dx.doi.org/10.23960/jpp.v14.i1.202419

Abstract

Mathematics education is looking for innovative methods to foster problem-solving skills in students. This research develops a problem-solving assessment using GeoGebra Classroom, a versatile interactive mathematics software, to revolutionize mathematics formative assessment and improve students' problem-solving skills. This study adopted the analysis, design, development, implementation, and evaluation (ADDIE) instructional design model stages. The design stage created a comprehensive assessment blueprint, incorporating GeoGebra Classroom functions to create interactive problem-solving tasks. Data analysis used both quantitative and qualitative approaches. Qualitative data consisted of feedback and suggestions from assessment experts, mathematicians, and GeoGebra specialists. Meanwhile, quantitative data included expert scores and cognitive tests that measured students' problem-solving abilities. A cognitive post-test was conducted to measure the progress of students' understanding while using the assessment product. The results of the content validity analysis, assessed using Aiken's V, ranged from 0.85 to 0.92, indicating a high level of validity for the problem-solving skills assessment in terms of content and construction. Some revisions were made to the design of the developed media to make it more interactive for students. These findings suggest that we can further use problem-solving questions integrated with GeoGebra Classroom to uncover the problem-solving skills of junior high school students.

Abstract

Students often struggle to identify relevant analog problems when solving new tasks, highlighting the need for teachers to design simple analog problems that serve as scaffolding. This study aims to analyze prospective teachers’ analogical reasoning processes in simplifying complex geometry problems using the Analogical Reasoning in Mathematics (ARM) framework. This qualitative research involved 34 prospective mathematics teachers from a public university in Surabaya, Indonesia. Participants were selected through purposive sampling based on their academic performance and prior coursework in geometry and problem solving. Data were collected through task-based interviews, written work, and observations during problem-simplification activities. The collected data were analyzed thematically, guided by the components of the ARM framework. The results indicate that prospective teachers with varying ability levels employed different analogical reasoning strategies to simplify complex problems through ARM activities. High-ability prospective teachers identified a broader range of student difficulties and adapted the problems into two-step analog problems featuring variations in visual representations, number of circles, and geometric shapes. Conversely, low-ability prospective teachers focused on difficulties related to verbal representation and the need for concrete numerical information, adapting the problems into single, highly simplified analog problems with specific images and numbers. Overall, prospective teachers actively utilized analogical reasoning to design analog problems that addressed student difficulties. Differences in ability were associated with the complexity of adaptation strategies and the depth of difficulty identification, underscoring the importance of training prospective teachers to integrate both approaches to effectively support student understanding.

Abstract

This study aims to describe the analogical reasoning of senior high school students with reflective and impulsive cognitive styles, particularly those with high mathematical ability, in solving open-ended problems. Analogical reasoning ability is important for students' success in understanding and solving mathematical problems. This study uses a qualitative approach with high school students selected based on their reflective and impulsive cognitive styles and high mathematical ability. Data were collected through the Matching Familiar Figure Test (MFFT) adapted from Warli, an analogy reasoning test using open-ended problems from SPLTV material, and interviews. Data analysis was based on analogy reasoning indicators, including the structuring, mapping, applying, and verifying stages. The results of the study indicate that reflective and impulsive students with high mathematical ability, both of whom are female, are able to perform all four stages of analogical reasoning well, identify problem elements, map similarities, apply strategies, and verify their work accurately.

Abstract

Problem posing is important in learning mathematics because it improves reasoning, critical thinking, and creative thinking skills. However, many students still find it difficult to pose problems. Through collaborative problem posing, students can exchange their understanding. The use of GeoGebra in problem posing can help students play an active role in generating ideas to construct new problems through its features. This research is a qualitative research that aims to describe the collaborative semi-structured problem posing of junior high school students assisted by GeoGebra in high groups. This research was conducted in one of the junior high schools in Surabaya class IX odd semester of the 2024/2025 school year in the age range of 14-15 years. The research data were collected through Problem Posing Test and Focus Group Discussion. The research subjects were a group with high mathematical ability consisting of two students. The results showed both members in the group contributed to each other for the new problem created. On knowledge base, they identified mathematical facts, concepts, and procedures. On heuristics and schema, they explored GeoGebra to come up with ideas. On group dynamics and interactions, they performed processes of normality, conformity, and innovation. In individual consideration of aptness, both members argued that each individual was skilled in proposing problems and the problems they created were acceptable to group members. Student had no problems during discussion and expressing their opinions due to their equal mathematical ability. Therefore, further research is needed on whether collaborative problem posing using GeoGebra heterogeneous groups also works. ABSTRAK Pengajuan masalah merupakan hal penting dalam belajar matematika karena meningkatkan kemampuan penalaran, berpikir kritis, dan berpikir kreatif. Namun, masih banyak siswa merasa kesulitan dalam pengajuan masalah. Melalui pengajuan masalah kolaboratif siswa dapat saling bertukar pemahaman. Penggunaan GeoGebra dalam pengajuan masalah dapat membantu siswa berperan aktif memunculkan ide-ide untuk mengkonstruksi masalah baru melalui fitur-fiturnya. Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mendeskripsikan pengajuan masalah semi terstruktur kolaboratif siswa SMP berbantuan GeoGebra pada kelompok tinggi. Penelitian ini dilakukan di salah satu SMP di Surabaya kelas IX semester ganjil tahun ajaran 2024/2025 pada rentang usia 14-15 tahun. Data penelitian dikumpulkan melalui Tes Pengajuan Masalah dan Focus Group Discussion. Subjek penelitian merupakan kelompok dengan kemampuan matematika tinggi yang terdiri atas dua siswa. Hasil penelitian menunjukkan kedua anggota dalam kelompok saling berkontribusi untuk masalah baru yang dibuat. Pada basis pengetahuan, mereka mengidentifikasi fakta, konsep, dan prosedur matematika. Pada heuristik dan skema, mereka mengeksplorasi GeoGebra untuk memunculkan ide-ide. Pada dinamika dan interaksi kelompok, mereka melakukan proses normalitas, konformitas, dan inovasi. Pada pertimbangan individu atas kesesuaian, kedua anggota saling berpendapat bahwa tiap individu terampil dalam mengajukan masalah dan masalah yang mereka buat dapat diterima anggota kelompok. Siswa tidak memiliki masalah selama berdiskusi dan mengungkapkan pendapat dikarenakan kesetaraan kemampuan matematika. Oleh karena itu, perlu penelitian lebih lanjut terkait apakah pengajuan masalah kolaboratif pada kelompok heterogen berbantuan GeoGebra juga berjalan demikian.

Abstract

This study investigates the individual and collaborative designs of context-based numeracy tasks developed by mathematics teachers employing three different contexts, namely, Islamic inheritance law, population census, and genetics. The tasks were designed at different levels of knowing, applying, and reasoning. The obtained data were analyzed using PISA’s contextual framework and Indonesia’s cognitive taxonomy to evaluate task solvability, context type, context level, and cognitive demand. The results show significant differences: most individual designs remained at the knowing level (88.23%), had first-order contexts (88.23%), and had 19.05% of tasks that could not be solved due to insufficient information. Collaborative designs eliminated all tasks that could not be solved, increased the number of reasoning-level tasks from 7.84% to 24.39%, and removed all zero-order context levels. Both preferred social settings (52%), but collaborative designs showed more integration. For example, context-based numeracy problems created individually ask students to determine the percentage of Generation Z. In contrast, group-created problems ask them to analyze the impact of demographics on planning. These findings demonstrate the importance of teacher collaboration in increasing the authenticity and complexity of learning activities. Systematic collaboration frameworks should be incorporated into teacher professional development programs.
