Abstract

Penelitian ini bertujuan mengembangkan modul pembelajaran matematika berbasis Culturally Responsive Teaching (CRT) pada materi Sistem Persamaan Linear Dua Variabel (SPLDV) dengan mengintegrasikan unsur budaya lokal Jambi untuk meningkatkan kemampuan berpikir kritis siswa. Penelitian ini menggunakan metode design research tipe development study yang terdiri atas tiga tahap, yaitu preliminary, prototyping (meliputi self-evaluation, expert review, one-to-one, small group, dan field test), serta assessment phase. Subjek penelitian melibatkan dua dosen ahli, seorang guru matematika, dan siswa kelas IX SMP Negeri 12 Kota Jambi. Pengumpulan data dilakukan melalui angket validasi, angket kepraktisan, tes kemampuan berpikir kritis, dan wawancara, kemudian dianalisis secara deskriptif kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa modul berbasis CRT memiliki tingkat kevalidan yang sangat baik dengan skor validasi materi sebesar 77,61% dan validasi desain sebesar 80,86%, serta dinilai sangat praktis dengan persentase kepraktisan 84,70% dari guru dan 79,99% dari siswa. Selain itu, modul ini terbukti efektif meningkatkan kemampuan berpikir kritis siswa, yang ditunjukkan oleh peningkatan rata-rata nilai pre-test sebesar 26,44% menjadi post-test sebesar 80,53%. Dengan demikian, modul berbasis CRT layak digunakan sebagai bahan ajar alternatif yang mampu meningkatkan kemampuan berpikir kritis melalui pembelajaran matematika yang kontekstual dan berlandaskan budaya lokal.

Abstract

Learning geometric transformations often presents challenges for students due to their abstract nature and limited connection to real-world contexts. Reflection is one of the most difficult concepts for students to understand. This study aims to design a Hypothetical Learning Trajectory (HLT) for geometric reflection using the PMRI approach through the context of Batik Jambi. This research employed a design research approach in the preliminary design phase, with data co llected through teacher interviews and literature studies. The result is a five-stage HLT design that utilizes the Bungo Melati motif as a symmetry context, guiding students from concrete experiences toward formal understanding through progressive mathematization. The findings indicate that incorporating the Batik Jambi context can enhance students’ comprehension of reflection while also connecting mathematics learning with local cultural values. This HLT design has the potential to serve as a foundation for developing a Local Instructional Theory (LIT) for more meaningful and contextualized geometry learning.

Abstract

Indonesian students’ relatively low performance in PISA has been closely linked to their difficulties in applying mathematical knowledge to real-world contexts, which often led to errors. The main objective of this study was to explore the types of mistakes students made when solving PISA-type questions within the content area of uncertainty and data. This research was qualitative descriptive in nature. The research subjects consisted of five ninth-grade students from a junior high school in Jambi Province, selected based on teacher recommendations. Data were collected through tests and interviews. The results of the study showed that students frequently made mistakes at the stage of writing the final answer, primarily due to difficulties in interpreting the given information and focusing too heavily on calculation procedures while overlooking what the problem was actually asking. These findings provide a basis for further research on analyzing students’ mathematical literacy skills in solving PISA questions, particularly within the domain of uncertainty and data.

Abstract

This study aims to analyze junior high school students’ critical thinking skills in solving problems related to Systems of Linear Equations in Two Variables (SPLDV). The research employed a descriptive qualitative approach and was conducted at SMP Negeri 9 Kota Jambi involving 32 ninth-grade students. Data were collected through contextual essay-type SPLDV tests designed based on six critical thinking indicators proposed by Facione, namely interpretation, analysis, evaluation, inference, explanation, and self-regulation. In-depth interviews were also conducted to support and clarify the test results. Data analysis followed an interactive model consisting of data reduction, data display, and conclusion drawing. The findings indicate that students’ critical thinking skills have not developed evenly across all indicators. Interpretation skills were relatively better developed, while evaluation, inference, explanation, and self-regulation remained at low levels. Most students were able to identify relevant information and construct mathematical models; however, they experienced difficulties in evaluating solution procedures and drawing logical conclusions. These results highlight the need for mathematics learning strategies that emphasize analytical reasoning, evaluation, and reflective thinking to enhance students’ critical thinking skills, particularly in learning SPLDV.

Abstract

This study aims to describe students' critical thinking skills in solving mathematical problems, particularly in geometry. The indicators used refer to Facione’s framework, which includes interpreting, analyzing, applying, evaluating, and concluding. This research employs a qualitative descriptive method with ninth-grade students as the research subjects. Data were obtained from students’ written test results and supported by interviews to explore their reasoning processes. The findings reveal that students’ critical thinking skills remain relatively low, especially in evaluation and conclusion. Most students can interpret and apply concepts but have difficulty analyzing problems deeply or verifying their solutions. These results indicate the need to develop innovative teaching materials and learning strategies to enhance students’ critical thinking skills.

Abstract

Statistical literacy is a critical competence for 21st-century students, yet many struggle to apply statistical concepts in authentic contexts. This study reports the development of JUMPISA, a PISA-based Jumping Task contextualized for secondary students in Jambi Province, designed to enhance students’ abilities to interpret, represent, and reason with data. Employing a design research approach with iterative development, the study included preliminary and formative evaluations to assess task validity and feasibility. The JUMPISA tasks integrate content on uncertainty, work-related contexts, and varying reasoning levels in line with PISA’s framework. Results indicate that students demonstrated notable improvement in engaging with authentic statistical problems. Beyond practical effectiveness, this study advances the theoretical understanding of context-sensitive PISA Task design, showing how locally contextualized, inquiry-driven tasks can be systematically developed and validated for international assessment. JUMPISA exemplifies a model for aligning global assessment frameworks with local educational contexts, offering guidance for both researchers and practitioners in designing assessment-informed instructional activities.
