Abstract

Kesulitan belajar merupakan suatu kondisi dimana mahasiswa tidak dapat belajar dengan baik. Tujuan penelitian ini adalah untuk menganalisis kesulitan mahasiswa dalam menyelesaikan soal pemahaman matematis pada mata kuliah teori peluang. Penelitian ini merupakan penelitian kualitatif dengan jenis penelitian deskriptif. Adapun subjek dalam penelitian ini adalah mahasiswa semester VI tahun akademik 2020-2021 pada program studi pendidikan matematika yang mengambil mata kuliah teori peluang di IKIP PGRI Pontianak. Instrumen penelitian yang digunakan adalah tes dan wawancara dengan teknik pengumpul data menggunakan teknik pengukuran dan komunikasi langsung. Adapun teknik analisis data yang digunakan adalah reduksi data, penyajian data serta penarikan kesimpulan. Hasil penelitian menunjukkan bahwa mahasiswa dengan kemampuan tinggi (M1) mengalami sedikit kesulitan belajar yakni dalam menyelesaikan soal pemahaman matematis pada indikator instrumental. Selanjutnya untuk mahasiswa dengan kategori sedang (M2) kurang dalam memahami konsep peluang dan pemahaman instrumentalnya, sedangkan untuk pemahaman relasional nya baik. Pada mahasiswa dengan kategori rendah (M3) ditemukan tidak memahami konsep peluang khususnya terkait penulisan anggota ruang sampel dan peristiwa, tidak dapat menghitung nilai peluang, tidak memahami konsep integral sehingga salah dalam menentukan hasil akhir nilai ekspektasi, dan tidak memahami konsep fungsi kepadatan peluang. AbstractLearning difficulty is a condition where students cannot study well. The purpose of this study was to analyze students' difficulties in solving mathematical problems in probability theory courses. This is qualitative descriptive research. The subjects in this study were the sixth-semester students of the 2020-2021 academic year in the mathematics education study program who took the opportunity theory course at IKIP PGRI Pontianak. The research instruments used were tests and interviews with data collection techniques using measurement techniques and direct communication. The data analysis technique used is data reduction, data presentation, and conclusion. The results showed that students with a high ability (M1) experienced a little difficulty in learning, namely in solving mathematical understanding questions on instrumental indicators. Furthermore, students in the moderate category (M2) lack understanding of the concept of opportunity and its instrumental understanding, while relational understanding is good. It was found that students in the low category (M3) did not understand the concept of probability, especially regarding the writing of sample space members and events, could not calculate the probability value, and did not understand the integral concept so they were wrong in determining the final expected value, and did not understand the concept of the probability density function.

Abstract

Many students encounter learning obstacles when understanding the volume of cylinders and cones; however, few studies have explicitly integrated these obstacles into didactic design. This study aimed to develop a didactic design to address specific learning obstacles in understanding the volume of cylinders and cones. Using a Didactic Design Research (DDR) approach grounded in Brousseau’s Theory of Didactic Situations, the study involved 28 seventh-grade students and a mathematics teacher from a junior high school in Pontianak, selected through purposive sampling. Data were collected through observations, diagnostic tests, and interviews and then analyzed qualitatively using interpretative and critical techniques. The didactic design consisted of four didactic situations: action, formulation, validation, and institutionalization, implemented in classroom practice. The institutional phase revealed several limitations, particularly a lack of sufficient scaffolding and inadequate visual support for students’ spatial reasoning. The findings indicate that addressing epistemological obstacles, such as misconceptions regarding the interpretation of height and base area in three-dimensional solids, can enhance students’ conceptual understanding. The study suggests that integrating learning obstacle analysis into didactic design helps refine future implementations to better anticipate students’ cognitive development.

Abstract

This study was motivated by students’ low mathematical problem-solving skills and the suboptimal use of engaging and interactive learning media in mathematics instruction. The purpose of this study was to determine the validity, practicality, and effectiveness of an interactive flipbook created using Canva on problem-solving skills in statistics for eighth-grade students at SMP Negeri 21 in Pontianak. This study employed the Research and Development (R&D) method using a modified 3D version of the 4D development model, namely define, design, and develop. The research subjects consisted of several validators, including subject matter experts and media experts, as well as 28 eighth-grade students from Class VIII C at SMP Negeri 21 in Pontianak. Data collection techniques included validation sheets, teacher and student response questionnaires, and problem-solving ability tests. The results showed that the validity level of the Canva-assisted interactive flipbook achieved an average percentage of 88.58%, meeting the criteria for “highly valid.” The practicality level achieved an average percentage of 94.46%, meeting the criteria for “highly practical.” Meanwhile, the effectiveness level, based on the students’ posttest results, reached 71.43%, meeting the “effective” criterion. Thus, the Canva-assisted interactive flipbook for eighth-grade statistics material is deemed highly valid, highly practical, and effective, making it suitable for use in mathematics instruction to support students’ problem-solving skills.

Abstract

Adaptive reasoning is one of the essential mathematical competencies that enables students to think logically, provide justification, draw conclusions, and evaluate mathematical arguments. However, many students still experience difficulties in applying adaptive reasoning when solving mathematical problems, particularly in the topic of social arithmetic. This study aimed to describe junior secondary school students' adaptive reasoning abilities in solving social arithmetic problems based on ability categories. The study employed a qualitative descriptive method with a case study approach. The research subjects consisted of three Year 7 students at SMP Kristen Ekklesia Kembayan, representing the high, moderate, and low ability categories. Data were collected through written tests and interviews. The instruments used were an adaptive reasoning test and interview guidelines. Data analysis was conducted through the stages of data reduction, data display, and conclusion drawing. The findings revealed that students in the high-ability category were able to fulfil all indicators of adaptive reasoning, namely making conjectures, providing reasons or evidence, drawing conclusions, examining the validity of arguments, and identifying mathematical patterns. Students in the moderate-ability category generally fulfilled most of the indicators but still encountered difficulties in providing complete mathematical justifications. Meanwhile, students in the low-ability category were unable to fulfil the indicators consistently due to misconceptions and difficulties in explaining the reasons underlying their answers. Therefore, adaptive reasoning skills need to be developed through learning activities that encourage students to provide explanations, justifications, and mathematical arguments. Keywords: adaptive reasoning, social arithmetic, junior secondary school students, qualitative study.

Abstract

This study was motivated by the low quality of Indonesian students' mathematical concept understanding, as shown by the PISA 2022 results, and by preliminary observations at SMP Mujahidin Pontianak indicating a relationship between the level of math anxiety and students' conceptual understanding ability. This study aimed to (1) describe the mathematical concept understanding ability of junior high school students experiencing math anxiety, (2) analyse the relationship between the level of math anxiety and mathematical concept understanding, and (3) identify the factors causing math anxiety among junior high school students. A descriptive qualitative approach was employed. The research subjects were eighth-grade students of SMP Mujahidin Pontianak in the 2025/2026 academic year, selected based on their level of math anxiety (high, moderate, and low). Data were collected through a questionnaire, a concept-understanding test on the topic of circles, and in-depth interviews, then analysed through data reduction, data display, and conclusion drawing/verification. The results revealed a consistent pattern: the higher the students' math anxiety, the lower their conceptual understanding, particularly on the interpretation and extrapolation indicators. Students with low anxiety demonstrated the most comprehensive understanding, those with moderate anxiety showed fairly good but inconsistent understanding, while students with high anxiety experienced serious cognitive obstacles. Three interrelated factors causing math anxiety were identified: personality (psychological/emotional), intellectual, and environmental/social factors, which jointly influenced the intensity of students' math anxiety. These findings suggest that teachers need to address the somatic, cognitive, and attitudinal dimensions of anxiety simultaneously while strengthening students' interpretation and extrapolation skills through supportive, anxiety-reducing instructional strategies.
