Abstract

Learning mathematics is considered a difficult subject for students. Learning difficulties experienced by students often have an impact on the lack of awareness of the importance of mathematics in students' daily life. Optimization of learning mathematics with problem-based learning can be applied using the 3N teachings of Tamansiswa concepts, namely Niteni, Nirokke, Nambahi. This research is qualitative in the form of a literature review. This article describes how teachers can optimize PBL with Tamansiswa teachings in learning mathematics so that students become enjoy, more effortless, and responsive in applying mathematical concepts in daily life.

Abstract

Errors in associating some knowledge result in students' mistakes in choosing strategies so that problems cannot be solved. In fact, the new curriculum in Indonesia requires students to be able to solve problems that require higher-order thinking skills. This study aims to describe how students process problems in solving bridge context problems. This research is qualitative research with case study method. This research was conducted in April 2022 with the research subject being a junior high school student in Yogyakarta, Indonesia. The instrument in this research is the problem of high order thinking (HOT) to measure problem solving ability. The instrument was designed based on the mathematics material that students had learned and compiled through five times Focus Group Discussion (FGD) by 3 mathematics lecturers. Data were collected using documentation and interviews then will be analyzed descriptively. Based on the results and discussion presented in the previous section, the authors collect three types of errors in solving problems made by students. The three types of errors are operational, conceptual, and principal errors.

Abstract

This research is motivated by technological advances that are developing more rapidly so that it can be used to improve students’ numeracy and digital literacy. This research aimed to analyse the impact of applying Ethnomathematics using the Trello application in increasing university students' numeracy literacy and digital literacy. This research used a survey method on 56 students. The research instruments used were a numeracy literacy test in the mathematics-chemistry one course, a digital literacy questionnaire, and an interview sheet. This research shows that implementing ethnomathematics utilising the application of Trello has several advantages, including increasing university students' numeracy and digital literacy.

Abstract

This study aims to develop an interactive learning media based on e-learning using Google Sites with the Tri-N approach (Niteni, Nirokake, Nambahi) to enhance students' learning motivation in the Statistics material for eighth-grade junior high school students. The research method employed is Research and Development (R&D) using the 4D development model, consisting of the Define, Design, Develop, and Disseminate stages. Data were collected through initial needs observation and product validation by media and material experts. The product developed is an interactive e-learning media containing teaching materials, instructional videos, practice exercises, and assessments based on the Kurikulum Merdeka. This media is designed to facilitate students' learning activities through the stages of Niteni, Nirokake, and Nambahi, with the expectation of encouraging active participation in the learning process. Due to time limitations, this research was conducted only up to the expert validation stage; practicality and effectiveness tests were not carried out. The validation results indicate that the Tri-N-based e-learning media is suitable for use in Statistics learning. In the future, this media has the potential to be further developed for other materials and educational levels as an innovative digital learning alternative for teachers and students.
