Abstract

This study aimed to compile a didactic design on social arithmetic material based on learning obstacles and learning trajectories experienced by students when learning the concept. The research method used was a Didactical Design Research (DDR) method with data collection techniques, namely observation, interviews, and learning obstacle tests. The first step in this study was to identify learning obstacles by testing learning obstacle instruments on grade VIII A students, with a total of 18 MTs Mu'allimat NW Anajani students who had received and learned the material. Before the learning obstacle test, researchers first examined the composition of the selected material, namely social arithmetic, in existing source books. Identified, the next step was the preparation of a didactic design with the use of learning theories that were in accordance with the expectations of obstacles when the learning obstacle test could be overcome or reduced. The didactic design that had been prepared was then implemented for grade VIII A students, with a total of 18 MTs Mu'allimat NW Anajani students in the even semester.

Abstract

During COVID-19, various obstacles were experienced during learning, including in learning mathematics. Learning had to be carried out online. Therefore, learning designs were also attempted to be made online. The learning design in this research was prepared using didactical design research. Participants in this research were 29 students at one of the junior high schools in Indonesia. The researcher was the main instrument in this research, along with several additional instruments, such as the fraction sequence test, interview guide, and online learning design. The data were analyzed using thematic analysis and qualitative analysis. The research results revealed that the factor that caused students to experience obstacles in ordering fractions was due to students’ low prerequisite knowledge regarding LCM (conceptual ontogenic obstacle). The online learning design offered then facilitated students to solidify their understanding of LCM before entering the core learning activities. Online learning design was also developed using the theory of didactical situations. After implementation, information was obtained that the learning obstacles experienced by students had no longer reappeared. Therefore, learning in schools should ensure that students have a good understanding of the prerequisites before starting the core learning activities.

Abstract

The COVID-19 pandemic disrupted educational practices worldwide, posing significant challenges for students, particularly in mastering foundational mathematical concepts such as fraction subtraction. In response to the urgent need for effective remote learning strategies, this study aimed to develop and implement an online didactic design to reduce student learning obstacles. Employing a Didactical Design Research (DDR) approach, the design process was supported by lesson study activities at each developmental phase to ensure instructional quality. Participants included 56 students from grades VII and VIII (ages 13 to 18). The researcher served as the primary instrument, supported by additional tools including a fraction test, interview guide, documentation study, and the online didactic design itself. Thematic analysis was used to identify learning barriers, while qualitative analysis assessed the effectiveness of the design implementation. Findings revealed that during the pandemic, students experienced both ontogenic and epistemological learning obstacles in subtracting fractions. However, after the online didactic design was introduced and implemented, these learning barriers were no longer evident. Remaining difficulties were attributed to internal, non-instructional factors, such as limited personal study time, rather than issues related to instructional delivery.  This study contributes to the field of mathematics education by providing an empirically grounded model for designing online instruction that addresses specific learning barriers. The findings underscore the importance of aligning didactic design with student learning needs, especially in crisis contexts, and highlight the potential of structured online approaches to support equitable mathematics learning.

Abstract

This study aims to develop Android-based learning media on the topic of curved surface geometry, named GeoFun App. The research method was a development research using the ADDIE model design. Participants in this study were ninth-grade students and mathematics teachers at one of the Islamic Junior High Schools (Madrasah Tsanawiyah) in East Lombok Regency, Indonesia, as well as two experts. The instruments used were media and material validation sheets, teacher and student response questionnaires, and learning outcome tests. Application validity analysis was conducted using Aiken’s V scale and the Likert scale. Absolute evaluation was used to test practicality, while the N-Gain method was applied to assess effectiveness. The research findings showed that the GeoFun App media met the validity criteria, with a validity score of 0.869 (material experts) and 0.844 (media experts), categorized as very valid. It achieved a practicality score of 60% from teachers (practical category) and 94.48% from students (very practical category). The result demonstrated an N-Gain of 76.3% and was categorized as effective. The GeoFun App possessed several unique superior characteristics, such as engaging assessments (quizzes, tests, and games), facilitating online and face-to-face learning, and integrating religious aspects (the use of Shalawat Nahdlatin and prayers on the initial display, as well as learning etiquette). Therefore, this study concluded that the GeoFun App met the criteria of validity, practicality, and effectiveness, as it was tailored to student needs and learning difficulties and was Android-based, making it familiar to students. The GeoFun App thus provides an alternative that teachers can use to optimize students’ mathematical competence in learning curved surface geometry. This study recommends that future research continue to enhance the application's compatibility so that it can be used on lower Android versions. Keywords: ADDIE model, curved surface geometry, GeoFun App.

Abstract

: Fractions are a fundamental mathematical concept that is quite important for life. However, the existing facts prove that fraction concepts in mathematics are a problem that has become a learning obstacle for students in schools. Therefore, this study aims to find alternative strategies to minimize the learning obstacle. The researcher then used a grounded theory design to find this strategy. Researchers also combined research design with phenomenology to find the core categories. Researchers used systematic analysis (open, axial, and selective), combined with thematic analysis with NVivo-12. The analysis results revealed that ontogenic in the form of participants were unable to simplify, determine equivalent fractions, and carelessness was the most significant learning obstacle. The strategy obtained was the use of a didactic design based on a didactical situation in collaboration with didactical design research, which would minimize student learning barriers on fractions. Keywords: fractions, learning obstacle, grounded theory, phenomenology, didactical situation. DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp87-99

Abstract

Multiplication of fractions is one of the operations on fractions that tends to be easy, but it becomes a problem for students. Only a little previous research has examined the multiplication of fractions and the factors that cause this problem at the tertiary level. This study aims to describe the factors that cause problems in terms of the types of learning barriers that students experience. The research design is hermeneutics phenomenology. The participants in this study were 15 students aged 18-25 years, 7 boys and 8 girls, 9 students majoring in natural sciences during high school, and 6 students from social studies majors. The researcher is the main instrument, with a fraction multiplication test consisting of 2 questions developed by NCTM and a semi-structured interview guide as an additional instrument. Data is processed using NVivo-12-assisted thematic analysis to simplify the coding process. The study revealed that students experienced more learning difficulties when working on non-routine fraction multiplication problems. For routine problems, students experience learning difficulties with the type of ontogenic obstacle that is psychological (not careful). For non-routine problems, students experience learning barriers with epistemological types because they rarely work on word problems, as well as ontogenic obstacles that are conceptual and psychological.

Abstract

Number patterns were one of the mathematical concepts that were studied in junior high school. This concept was useful, but students tended to experience problems when learning it. Quite a lot of research has studied number patterns, but not many have attempted to study alternative solutions to optimize problem-solving abilities and learning motivation, especially using lesson study activities based on didactical design research. Therefore, this research aimed to optimize students’ problem-solving abilities and learning motivation with the preparation of didactic designs through lesson study activities. This research was conducted at a private junior high school in Mataram, Indonesia. Participants in this research were ten class VIII students (six boys and four girls). The researcher was the main instrument, with several additional instruments, such as learning design, observation sheets on problem-solving abilities and learning motivation, as well as documentation studies. The data were analyzed using qualitative data analysis. The research results revealed that the number pattern learning design was able to optimize problem-solving abilities and student learning motivation. Several factors that caused these positive results were the existence of contextual problems as trigger situations in learning and learning activities adapted to students’ hobbies. The recommendation from this research was that learning design should be prepared using didactical design research based on lesson study.
