Fractions remain predominantly one of the most challenging topics to teach and learn. Brunei Darussalam is no exception, where a few local researches reported that students performed poorly in fraction topics. To understand this situation, this study focuses on pupils’ understanding in solving problems on fractions. Specifically, this study investigated Year 5 pupils’ conceptual and procedural performance on the addition of fractions. This study employed a quantitative research approach involving 572 primary school children. A test consisting of six carefully planned questions on fractions was used as the research instrument. The questions were divided into two sections to test pupils’ conceptual and procedural understanding laterally. The findings from this study revealed that children performed better in the procedural than in the conceptual questions. It can be concluded that most Year 5 pupils can correctly attempt the addition of fractions via procedural approach without understanding the essential concepts involved. Recommendation for future research was also discussed.

This research aimed to produce a valid and practical product in the form of a student worksheet using the Indonesian version of the Realistic Mathematics Education (PMRI) approach in the classroom context with an orientation toward students’ conceptual understanding and to figure out the potential effect of the student worksheet developed. It is a piece of development research under the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. Data collection was performed using documentation, a questionnaire, and a test. The object of this research was the development of a student worksheet using the PMRI approach within the classroom context with an orientation toward students’ conceptual understanding. Meanwhile, the subjects of the research were students of grade X of SMAN 06 Banyuasin. The research results showed that the student worksheet produced was declared valid (with an average score of 90.83), practical (based on the students’ questionnaire responses, with a score of 79.65), and potentially influential to a high degree (based on the students’ test results, with a percentage of 84%). Therefore, the student worksheet that was developed using the PMRI approach within the classroom context with an orientation toward students’ conceptual understanding was worth using in the learning process.

This study aims to produce valid and practical PISA-based numerical problems in the context of the pandemic period and to find out the role of the questions in the form of potential effects on the mathematical literacy skills of secondary school students. This research uses developmental research design, which has 2 stages, namely preliminary and formative evaluation (self evaluation, expert review, one-to-one and small group validation, and field test). The participants in this study were students in Grade 8 who were under the age of 15 and different levels of skills. Data analysis was done descriptively by conducting observations, tests, interviews, and document analysis. The research was conducted face-to-face and via Zoom and WhatsApp Group (WAG) to produce valid and practical PISA-like arithmetic questions. Based on the students' responses, it can be stated that the questions presented are in the practical category because they can be completed quickly by students, they can be understood well by students, and they have the potential effect on students' mathematical literacy skills. In addition, there is a diversity of answers between one students and another according to the level of difficulty that is appropriate for Grade 8 students. This proves that a PISA-like numeration problem in the context of the religious day during a pandemic can help improve students' mathematical literacy.

This research aimed to develop a didactic design of the concept of the surface area of a flat-sided prism by considering the stages of van Hiele’s theory as a learning trajectory. The didactic design of the concept of the surface area of a flat-sided prism based on van Hiele’s theory has been adapted to the pandemic situation and implemented to online learning. The research method employed was a qualitative method with data collected through observation, interviews, and documentation. The initial step in this research was to test the concept of the surface area of a flat-sided prism on 53 9th-grade students for the 2019/2020 school year to identify learning obstacles. Following the identification of the learning obstacles, an initial didactic design was then drawn up by applying the phases in van Hiele’s model of geometric thinking. The didactic design prepared was subsequently implemented online to 8th-grade junior high school students. The results of the implementation of the didactic design were analyzed as the final product. The conclusion from this research is that by using a didactic design that considers the stages of van Hiele geometry in understanding the concept of surface area of a flat-sided prism, it can help students understand the concept of a flat-sided prism correctly. It was found that students' understanding of the concept of the surface area of a prism improved from visual level to informal deduction.

Rotation (rotation) is one of the materials in the transformation of geometry. Rotational learning can be the basis for student understanding geometrically because of its dynamic nature. Rotational learning can allow students to relate some geometric concepts such as congruence and equivalence. The study aims to explore the students’ inductive reasoning in rotation problem through the context of songket Palembang pattern in class IX. This research is related to the Indonesian Realistic Mathematics Approach (PMRI) as a learning approach used. The methodology used in this study is Design Research type validation studies consisting of three stages: preliminary design, experimental design, and retrospective analysis. The study was conducted for IX grade students of SMP Negeri 1 Palembang. The learning path (Hypothetical Learning Trajectory) in design research plays an important role as a research design and instrument. The Hypothetical Learning Trajectory was developed together with a series of activities using the contet of songket Palembang pattern such as pucuk rebung pattern, lepus pattern, lintang pattern, etc. Data collected in the form of video recordings and photos during the learning process, student interviews, student work results, discussion results, and field notes at each meeting. The instruments used include documentation in the form of video recordings and photos, interview sheets, student activity sheets, field note sheets, and the Hypothetical Learning Trajectory (HLT). Media used in this study was the students’ worksheet.

This research aimed to develop a valid and practical electronic module that potentially affected the HOTS of grade 12 students during distance learning in Xaverius 1 High School, Palembang. This study employed the Alessi Trollip model orienting towards multimedia products consisting of three stages: planning, designing, and developing. The data collection techniques were validation sheet instruments, questionnaires, and tests. Meanwhile, the data analysis method were validation sheets and questionnaires through average scores and comments and test sheets through student work. The success criteria of this research were to obtain valid and practical geometry distance teaching materials with HOTS by considering experts’ and clients’ reviews. The expert validity revealed a score of 4.72 and was considered very valid. The questions’ score was 55.5% and was revised. Meanwhile, the questionnaire was categorized practical with a score of 79.3. The e-module potentially influenced HOTS exercises with an average score of 83.5 or very good. This research concludes that the developed e-module has valid and practical characteristics and can influence the HOTS thinking abilities to create and analyze. Thus, the module significantly supports the needs of teaching materials and increases the students’ HOTS.
