Abstract

Mathematical problem-solving ability among students remains low in conventional learning environments. The integration of Augmented Reality (AR) into the Indonesian Realistic Mathematics Education (PMRI) approach facilitates visualization of abstract concepts and promotes contextual learning. This study analyzes the effect of PMRI-based circle learning assisted by AR on students' problem-solving abilities. A quantitative approach was employed using a One Group Pretest pretest-posttest design with 35 eleventh-grade students from SMA Srijaya Negara Palembang. Data were collected through a mathematical problem-solving test based on Polya's four stages: understanding the problem, devising a plan, carrying out the plan, and looking back, administered before and after the intervention. The Shapiro–Wilk test indicated that the data were normally distributed (pretest = 0.084; posttest = 0.309, both > 0.05). Paired sample t-test analysis revealed a pretest mean score of 19.37 and a posttest mean score of 66.51, with a mean difference of 47.14. The t-test result (t = -23.053, Sig. (2-tailed) < 0.001) indicated a significant difference between pretest and posttest scores. These findings demonstrate that the PMRI-based learning design assisted by AR is effective in improving students' problem-solving abilities through contextual learning experiences and interactive visualization. The results suggest that integrating PMRI with Augmented Reality in circle learning represents an effective instructional innovation for enhancing students' problem-solving abilities.

Abstract

This study aims to develop a digital worksheet assisted by wizer.me on geometric transformation material, particularly translation and reflection, as an alternative learning medium that is more interactive for junior high school students. The development was carried out using the Plomp model through the preliminary, design, reconstruction, testing, evaluation and revision, and implementation phases. The results of validation by experts showed that the developed product had a very good level of validity in terms of content, construct, ICT, and language, with an average score above 87%. Meanwhile, the practicality test in a small group also showed a positive response from students with a score of more than 82%, indicating that the digital worksheet was practical to use in the learning process. The effectiveness of the media was tested by giving pretest and posttest questions to 28 students. There was a significant increase in learning outcome, with the average pretest and posttest scores increasing by 40.58 with N-gain value of 0.59, which is in the moderate category and is reinforced by the results of the Paired Sample t-Test, which shows a difference in scores before and after learning. Therefore, it can be concluded that digital worksheets assisted by wizer.me are quite effective in supporting students’ understanding of geometric transformation material, making them suitable for use as an innovative learning medium in the classroom.

Abstract

Spatial literacy is a vital math skill for students to learn during their three-dimensional geometry education. The two skills remain essential, yet most fifth-grade students struggle with spatial tasks. This challenge restricts their conceptual growth. The research examines fifth-grade students’ spatial literacy abilities and their error patterns to provide evidence for developing a Local Instructional Theory (LIT) on three-dimensional geometry. The research included 118 fifth-grade students (aged 10-11 years) from two public primary schools in Palembang who participated in a descriptive quantitative study with error analysis. The research data came from student performance on the spatial literacy diagnostic test and their error analysis records. The researchers applied descriptive statistics to determine average scores and establish performance levels for visualisation, reasoning, and communication skills. The researchers categorised student mistakes into four categories: procedural errors, conceptual errors, representational errors and communicative errors. The students produced results indicating significant differences in their performances. Students failed to perform basic procedural tasks, including spatial form comparison and application of formal notation, while they struggled with complex visualisation and the development of multiple-step spatial thinking and conceptual understanding. Students’ learning difficulties manifest as systematic errors, indicating that their challenges stem from complex, interconnected issues rather than random mistakes. The research results demonstrate that students need instruction which teaches them to develop their visualisation abilities, their reasoning skills, and explanatory competencies. The designs serve as an essential tool for uniting procedural fluency with conceptual understanding, leading to better spatial literacy in early geometry education.

Abstract

Penelitian ini bertujuan membandingkan tiga buku teks matematika-Kurikulum Merdeka, Kurikulum Tingkat Satuan Pendidikan (KTSP), dan The Singapore O-Level Curriculum-pada materi tabung dalam konteks literasi matematika. Metode yang digunakan adalah deskriptif-komparatif dengan analisis konten terhadap struktur materi, fakta, konsep, prinsip, distribusi soal berdasarkan taksonomi Bloom, soal pemecahan masalah, dan kesesuaian soal dengan framework PISA. Hasil penelitian menunjukkan bahwa buku teks kurikulum merdeka lebih menekankan konsep dasar namun miskin konteks dan variasi soal, buku teks KTSP mulai mengintegrasikan konteks nyata dan prinsip skalabilitas meski visualisasi terbatas, sedangkan buku teks The Singapore O-Level Curriculum unggul dalam visualisasi, variasi soal kognitif tinggi, serta proporsi soal pemecahan masalah dan konteks PISA yang seimbang. Penelitian ini menegaskan bahwa buku teks dengan materi visual, kontekstual, dan soal beragam lebih efektif meningkatkan literasi matematika siswa. Implikasinya, pengembangan buku teks perlu mengacu pada kerangka literasi matematika internasional agar pembelajaran matematika di Indonesia lebih relevan dan kompetitif.

Abstract

This study aimed to describe students’ perceptions of the use of Augmented Reality (AR)-based student worksheets in learning circle geometry. A descriptive quantitative approach was employed. The participants were 30 eleventh-grade students from a senior high school in Palembang selected using convenience sampling, as they were directly involved in learning activities using AR-based worksheets. Data were collected through a 20-item Likert-scale questionnaire covering cognitive, affective, and psychomotor/social aspects. Students’ responses were analyzed descriptively by calculating the percentage of response frequencies for each Likert-scale category and aspect to identify overall perception trends. The results indicated that most students expressed positive perceptions of AR-based student worksheets, particularly in supporting conceptual understanding, learning engagement, and classroom interaction. However, a considerable proportion of neutral responses was also observed, especially in the affective aspect, indicating variation in students’ emotional engagement. Overall, AR-based student worksheets were perceived as a supportive learning medium for circle geometry learning within the context of this study.

Abstract

Spatial literacy is a key competency in elementary geometry. However, students often face difficulties in visualization, spatial reasoning, and spatial communication, particularly in learning cubes and cuboids. Common challenges include visualizing nets, understanding volume as layered space, and using formal spatial terminology. This study aims to develop a local instructional theory (LIT) on the volume and surface area of cubes and cuboids to strengthen spatial literacy through a culturally grounded learning trajectory situated in the Sultan Mahmud Badaruddin II Museum. It involved 44 fifth-grade students (aged 10-11) and employed a validation study design consisting of preparing for the experiment, design experiment (pilot and teaching experiments), and retrospective analysis. Data were collected through classroom observations, video recordings, student worksheets, miniature products, and group discussions. The data were then analyzed qualitatively using triangulation. Findings reveal recurring misconceptions, such as incorrect cube nets, interpreting volume as a two-dimensional, conflating surface area and volume, and reliance on informal language. Students’ learning progressed from contextual exploration to formal representation using manipulatives, teacher scaffolding, and Augmented Reality (AR). The resulting LIT is defined by three principles: the integration of manipulatives and AR, an emphasis on inter-dimensional relationships, and the enhancement of formal spatial communication within a Pendekatan Matematika Realistik Indonesia (PMRI) and Project-Based Learning (PjBL) framework.
