Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kritis siswa dalam menyelesaikan soal materi peluang ditinjau dari tingkat self-efficacy. Penelitian dilaksanakan di SMAN 1 Sindue dengan pendekatan kualitatif deskriptif. Subjek penelitian terdiri dari siswa dengan kategori self-efficacy tinggi, sedang, dan rendah yang dipilih berdasarkan hasil angket. Data dikumpulkan melalui angket, tes tertulis, dan wawancara, sedangkan uji kredibilitas data dilakukan melalui triangulasi waktu. Hasil penelitian menunjukkan bahwa siswa dengan self-efficacy tinggi mampu memahami soal, mengaitkan konsep peluang secara logis, mengevaluasi hasil pengerjaan, serta menyusun strategi alternatif dengan kesimpulan yang tepat. Siswa dengan self-efficacy sedang menunjukkan pemahaman dan analisis yang cukup, namun masih terbatas dalam mengevaluasi dan mengaitkan konsep, sedangkan siswa dengan self-efficacy rendah mengalami kesulitan dalam memahami, menganalisis, dan menarik kesimpulan. Dapat disimpulkan bahwa kemampuan berpikir kritis siswa bervariasi pada setiap indikator dan dipengaruhi oleh tingkat self-efficacy masing-masing. Hasil ini mengimplikasikan pentingnya penguatan self-efficacy melalui pendekatan pembelajaran reflektif untuk meningkatkan kemampuan berpikir kritis matematis siswa.

Abstract

This study aims to describe the profile of junior high school students' mathematical abstraction in forming the concept of triangles in terms of high, medium, and low levels of mathematical ability, based on the stages of RBC+C, namely recognizing, building-with, constructing, and consolidation. This study uses a descriptive qualitative approach with three seventh-grade students as subjects, one student each with high, medium, and low mathematical ability, selected based on the results of a mathematical ability test. Data were collected through triangle abstraction assignments and interviews, then analyzed using the Miles and Huberman model which includes data condensation, data presentation, and drawing and verifying conclusions. The results showed that students with high mathematical ability were able to pass all stages of RBC+C optimally, students with medium ability were able to reach all stages but not optimally, while students with low ability experienced limitations in almost all stages of mathematical abstraction, especially in the aspects of building-with, constructing, and consolidation. Thus, the level of students' mathematical ability significantly influences the quality of the mathematical abstraction process in forming the concept of triangles.

Abstract

Abstract: The aim of this research is to develop a mathematics learning outcomes instrument. The plan includes: 1) designing a math learning grid for eighth-grade junior high school, 2) a math learning outcomes test, 3) content validation by relevant math learning experts, 4) analysis of math communication instrument, and 5) analysis of math connection instrument. The research results in a communication and math connection-based junior high school math learning outcomes instrument, involving teachers and students in continuous assessment system development. The focus is on effective communication and math connection aspects. The expected indicators include the instrument's effectiveness in detecting the extent of math communication and connection in preparing and implementing the learning process. This promotes a peaceful teacher-student relationship for both written and oral communication. Keywords: Learning Evaluation, Instrument Development, Communication, Math Connection, Effective Assessment.   Abstrak: Tujuan penelitian ini adalah untuk menghasilkan rancangan pengembangan instrumen hasil belajar matematika.

Abstract

The objective of this activity is to enhance the competencies of junior high school teachers in Sigi Regency in creating teaching modules using Problem-Based Learning (PBL) with a Teaching at the Right Level (TaRL) approach. This study employed a collaborative training design involving 32 junior high school teachers grouped into small teams of 3-4 members. The training activities were conducted through four stages: preparation and needs assessment, conceptual training and workshop implementation, implementation and mentoring, and evaluation and dissemination. Each group discussed creating teaching modules starting with formulating learning objectives, determining differentiated assessments, and designing learning steps by applying PBL syntax adapted to students' ability levels through the TaRL approach. The results showed that all groups successfully developed PBL-based teaching modules with a TaRL approach systematically and were able to conduct learning simulations effectively. This training proved effective in enhancing teachers' understanding of differentiated learning and their ability to design contextual learning that is adaptive to individual student learning needs.

Abstract

Research on mathematical creative thinking has examined various creativity indicators, but the use of multiple solution representations and the limitations of independent verification in solving similarity problems warrant further investigation. This study aimed to describe the creative thinking profile of a junior high school student with high learning motivation and an Idealist personality type when solving similarity problems. A qualitative approach with a case study design was employed. One participant was purposively selected from 32 students based on personality type identified using the Keirsey Temperament Sorter (KTS), learning motivation measured using the Mathematics Motivation Questionnaire (MMQ), and good communication skills. Data were collected through questionnaires, written tests, interviews, and documentation, then analyzed using the Miles and Huberman model. The results showed that the participant generated and applied two solution procedures: the scale factor method and the ratio method. However, both procedures relied on the same principle of proportionality and therefore did not provide sufficient evidence of flexibility in using distinct mathematical approaches. The novelty of the strategy also remained undetermined because no comparative data from other students were available. During the looking-back stage, the participant relied solely on the agreement between the results without conducting independent verification. These findings highlight the importance of distinguishing procedural success from metacognitive evaluation. Pedagogically, teachers can use reflective prompts to encourage students to check equations, similarity conditions, and the reasonableness of their answers. As the study involved only one case, the findings are not intended to be generalized to students with similar characteristics.

Abstract

This study aims to describe students’ numeracy literacy in solving data presentation problems based on mathematical disposition and self-efficacy. This is a descriptive study using a qualitative approach. The research subjects consisted of four seventh-grade students at Bala Keselamatan Christian Junior High School in Palu, namely students with high mathematical disposition and high self-efficacy (DTST), high mathematical disposition and low self-efficacy (DTSR), low mathematical disposition and high self-efficacy (DRST), and low mathematical disposition and low self-efficacy (DRSR). Data were collected through questionnaires, numeracy literacy tests, and interviews, and were analyzed using the Miles and Huberman model. The results indicate that there are differences in numeracy literacy characteristics across each student profile. DTST and DTSR students demonstrated better numeracy literacy characteristics than DRST and DRSR students. These differences were evident in the formulate, employ, and interpret processes. The findings indicate that mathematical disposition contributes to the quality of mathematical thinking processes, while self-efficacy plays a role in building students’ confidence while solving and communicating problem solutions.
