Abstract

This research aimed to optimize the representational abilities of prospective mathematics teachers through the implementation of hypothetical lecture designs. The research design used was didactical design research combined with lesson study activities. Participants in this research were 29 prospective mathematics teacher students (18–21 years old) at a private university in Mataram, Indonesia. The researcher was the main instrument, with several additional instruments, one of which was the hypothetical lecture design. After conducting qualitative data analysis, it was concluded that there was an increase in the percentage of students’ representation abilities through the implementation of hypothetical lecture designs. This was because the course design facilitated students to solve problems by exploring, using, and presenting ideas in various forms of representation. Apart from that, the lecture design integrated QR codes, Quizizz, and inspirational YouTube videos to attract students’ interest or motivation during lectures, especially when solving problems.

Abstract

Despite extensive research on mathematics within universities, yet exploration of alternative solutions for challenges students faced during mathematics lectures was limited. Particularly, integrating mobile technology assistance via didactical design research received little attention. Therefore, researchers tried to describe the role of mobile technology in supporting mathematics lectures at an Indonesian university. Didactic design research was the method used in this research. Participants comprised 53 students aged 18–25 years. The main research tools included the researcher, a math comprehension test, an in-depth interview guide, and a hybrid mathematics module with mobile technology support. Thematic analysis uncovered learning barriers, while lecture data underwent qualitative and retrospective analysis. The findings were low mastery of prerequisites, carelessness, and a limited context for lecture. The hybrid module was able to minimize mathematics student learning obstacles in higher education. This research recommends lecturers facilitate problem-based activities with mobile technology to enhance students competencies in higher education.

Abstract

Converting mixed numbers into common fractions is one of the formula problems in learning fractions which is a problem in learning. However, not many studies have examined this conversion. In addition, there are not many studies that try to provide solutions to the conversion problem. Therefore, this study aims to identify the types of learning barriers students experience when converting mixed numbers into common fractions and provide alternative solutions to minimize these learning barriers. The research design used to achieve this goal is didactical design research (DDR). DDR was chosen because it uses the results of identifying types of learning barriers to develop didactic designs in learning fractions. The participants in this study were math teachers with 26 years of age and less than 5 years of teaching experience. The main instrument in this study was the researcher using several additional instruments, such as fraction comprehension tests, interview guides, and didactic designs. The data was then analyzed using qualitative data analysis. The results of the study revealed that students indicated that they experienced learning difficulties with different types of epistemological obstacles because they rarely start learning with everyday life problems. The solution offered in the didactical design is the use of the problem as an initial situation in learning which students will then respond to in the form of a didactical situation. The recommendations offered in this study are the implementation of the didactic design itself.

Abstract

The lack of instruments designed to assess chemical literacy among prospective chemistry teachers highlights the need for robust tools to support science education. This study develops and validates an instrument to measure chemical literacy, addressing this gap and contributing to improved pedagogical practices. In this study, a chemical literacy instrument for general chemistry was developed, drawing on existing frameworks of chemical literacy. This research employs a development-based approach (RD), encompassing literature review, instrument development, and quality testing. The quality of the instrument was evaluated based on its reliability and validity. The validity was evaluated by expert panel review, difficulty index, discrimination index, and pearson correlation value. In this study, a multiple-choice chemical literacy test instrument was successfully developed using the PISA 2025 scientific literacy framework, resulting in 23 valid items. The PISA framework was chosen for its perceived dynamism compared to other frameworks. The reliability of the developed instrument reached 0.818, indicating that the questions are highly reliable. Future improvements to the instrument are necessary, with a focus on ensuring that all items fully meet the established validity criteria

Abstract

The connection between sustainability-based education and scientific literacy, particularly in the field of chemistry, is becoming increasingly significant. Therefore, a chemical literacy instrument needs to be integrated with sustainability contexts as a further development to equip students with a holistic understanding of the sustainable development goals. This study aims to create and validate a chemical literacy instrument aligned with sustainability contexts, focusing on atomic structure and periodic properties of elements. The instrument development process included item creation, content validation, and reliability analysis. The study involved chemistry education students from a university in Indonesia (N = 83). The instrument achieved expert validation with a validity index value of 0.95. Through Rasch analysis, 21 valid items with high reliability were identified, including 18 multiple-choice questions (r = 0.833) and 3 essay questions (r = 0.817). The instrument demonstrated effective distractor functionality, as well as acceptable values for the discrimination index, difficulty index, outfit mean square, and z-standardized. These results confirm the reliability and validity of the instrument in assessing chemical literacy within sustainability contexts, specifically focusing on good health and well-being. The instrument is recommended as a dependable tool for measuring chemical literacy in sustainability contexts. This research contributes to advancing chemical literacy to address global sustainability challenges

Abstract

This study analyses how the STEAM+X framework has been implemented in mathematics education. The “X” component represents additional disciplines beyond the traditional STEAM fields, such as culture, history, and architecture. The systematic literature review (SLR) follows the PRISMA protocol. The initial search returned 350,190 documents, but only one article met the rigorous inclusion criteria focused explicitly on STEAM+X in mathematics education. This finding underscores the topic’s novelty and the need for further research. The selected study highlights the integration of geometry, digital and physical technologies (e.g., GeoGebra, AR/VR, 3D printing), and educational levels, including high school and teacher education. The analysis reveals limited implementation across countries and a lack of diversity in content areas. These results call for expanded investigations into STEAM+X practices incorporating broader mathematical domains, varied cultural contexts, and more inclusive educational levels.

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

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

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.
