Nurjanah was born in Purwakarta, West Java, Indonesia on November 16, 1965. She began elementary education at SDI Singawinata 2 Purwakarta in 1972 and continued her junior high school at SMP Negeri 1 Purwakarta in 1978. Then she continued her education at SMA Negeri 1 Purwakarta in 1981 In accordance with his interests, he continued his studies at the Teachers and Education Institute of Bandung in 1984 majoring in mathematics education. He then took a master's program in mathematics education in 1990 at the State University of Malang which enabled him to teach discrete mathematics courses, mathematics learning planning, evaluation of mathematics learning, mathematics teaching and learning strategies, mathematics learning media and mathematics education problem studies. In 2010 he continued his mathematics education doctoral program at an Indonesian university of education. He has done extensive research on the development of hands-on activities and computer-based media whose products are published in highly reputable journals.

Exploring three-dimensional geometry using praxeological analysis: Indonesian textbook insights Ratri Isharyadi, Nurjanah Journal on Mathematics Education, 2025 The integration of three-dimensional geometry in secondary mathematics education plays a crucial role in developing students' spatial reasoning and problem-solving skills. However, textbooks often present limitations in structuring tasks, techniques, and justifications, which may lead to learning obstacles. Despite the importance of well-designed instructional materials, there is a lack of comprehensive studies analyzing Indonesian mathematics textbooks using both the praxeological framework and the learning obstacles perspective in didactic situations. Addressing this gap, this study examines a Grade XII mathematics textbook in Indonesia, focusing on three-dimensional geometry through a structured content analysis. The analysis categorizes tasks based on praxeological components, including types of tasks, solution techniques, technological justifications, and supporting theories, while also identifying potential learning obstacles related to the clarity of visual representations and contextual problem diversity. The findings reveal that the textbook includes 10 types of tasks, solved using 6 techniques, supported by 7 forms of technological reasoning, all grounded in three-dimensional geometry concepts. The presentation of tasks is systematically structured and balances conceptual and procedural aspects, minimizing significant didactic obstacles. However, epistemological obstacles were identified, primarily due to limited visualizations and a lack of diverse contextual tasks, which may hinder students’ flexibility in applying three-dimensional geometry concepts. These findings highlight the need for improved task design and enhanced visual representations to foster deeper conceptual understanding and adaptability in problem-solving. This study contributes to mathematics education research by providing empirical insights into textbook design and its impact on students' learning processes, offering recommendations for more effective instructional material development.
Development of a STEM-based digital learning space platform to enhance students’ mathematical creativity in future learning classrooms Ricki Yuliardi, Yaya Sukjaya Kusumah, Nurjanah Nurjanah, Dadang Juandi, Suparman Suparman Eurasia Journal of Mathematics Science and Technology Education, 2024 This study focuses on developing a web-based digital learning space (DLS) designed to support a STEM learning model that fosters students’ mathematical creativity. The DLS builds upon traditional learning management systems by introducing customizable elements tailored to individual teaching and learning environments (PTEs and PLEs). These features allow for the formation of diverse learning networks within the DLS. This enhanced version integrates frameworks for STEM learning, engaging activities, instructional videos, quizzes, evaluations, feedback tools, and a chat feature for direct communication with instructors. The research and development process employed a 4D model–define, design, develop, and disseminate–and involved validation from content and media experts, confirming the DLS’s reliability for broader testing. Results indicate that the STEM-based DLS is highly suitable for mathematics education, as shown by validation from experts, practicality tests from users, and effectiveness tests that measured students’ mathematical creativity. This study also found moderate improvement in students’ creative mathematical thinking (Ng = 0.554) within classrooms using the STEM-based DLS, highlighting its effectiveness for enhancing these skills. Thus, this STEM-focused DLS offers a mobile-friendly digital environment that effectively promotes students’ mathematical creativity.
Flat plane geometry learning media through macromedia flash CS3 program in online mathematics learning Nurjanah, JA Dahlan, Y Wibisono Journal of Physics Conference Series, 2021 A learning media is one of the many tools that are being developed by teachers to help students learn mathematics. Because of that, the learning media must be designed to fit the students’ characters. Junior high school students need a learning media that fits with the level of concrete thinking so that students are able to adapt the mathematical knowledge that are beginning to get abstract. For this purpose, scientists have tried to improve the learning media that are technology based using Adobe Flash CS3 program. The technology-based learning media using Adobe Flash CS3 have been tested in online learning practices which took part 124 students from several junior high schools in Bandung, as well as math teachers as observers. The results of this implementation show that improved computer-based learning media are responded positively by students. The students feel motivated to study, focused, and highly curious. This response is supported by their comments that the improved media is appealing, well organized system, and the animation has helped them to understand the material.
Error analysis in solving the linear equation system of three variables using Polya's problem-solving steps R B Wiyah, Nurjanah Journal of Physics Conference Series, 2021 Recently, students still often have difficulties and share common mistakes in solving the linear equation system of three variables. This qualitative descriptive research describes the errors and causes of students’ errors in solving the linear equation system of three variables using Polya’s problem-solving steps. The subjects were 33 students of Grade 10 Science at one of the Senior High School in Indralaya. The data collection techniques used observation, student worksheets, and interviews. The results showed there were several students’ errors and the causes of students’ errors in solving the problems. These errors are errors in identifying the known and asked information, errors in making mathematical models of problems, errors in calculations, errors in arranging the linear equation system of three variables, and errors in giving valid reasons for their answers. The causes of these errors are the limited time for understanding the problem, careless in doing calculations, forgetting the formulas, and lacking understanding of variables concept.
Ethnomathematics study of Minangkabau tribe: formulation of mathematical representation in the Marosok traditional trading Nurjanah Nurjanah, Isra Mardia, Turmudi Turmudi Ethnography and Education, 2021 This research aims to explore the use of ethnomathematics in revealing mathematical representations and in the formulation of a calculation system used in the Marosok trading tradition by the Minangkabau tribe in West Sumatra. Ethnomathematics studies ideas in various cultural activities practiced by ethnic, social, or professional groups. The tradition involves nonverbal communication, such as shaking hands with ‘Marosok’ or touching covered fingers to obtain price agreements in trading livestock. Therefore, this study was conducted using qualitative approaches and the ethnographic method via field notes, unstructured interviews, and documentation studies. The findings showed that mathematical representations of finger symbols and gestures in the Marosok Tradition contain basic numbers. These include half, one, two, two and a half, three, four, five, etc. with functions, such as addition and subtraction, which are used to obtain other numbers needed in livestock trading transactions using specific formulas.
