Buna is one of the woven motifs from Insana, East Nusa Tenggara Province that uses geometric motifs like a rhombus. Rhombus is a challenging material so students only memorize the formula without understanding the concept. In order to overcome this problem, a weaving learning based on ethnomathematics has been proposed. The purpose of this study is to understand the impact on the learning achievement of students of the implementation of a realistic mathematical approach based on ethnomathematics. This is a quantitative study using a one-group pretest-posttest design. The population for this study is all fifth-grade students of SDN Bestobe, Insana District. Pretest and posttest results obtained are used for the analysis. The statistical test used is a paired sample t-test. The results show that the implementation of realistic mathematical learning based on ethnomathematics has a substantial influence on the learning achievement of mathematics students. These results contribute to adding empirical evidence related to the relationship between Ethnomathematics-based Realistic Mathematics Education approaches to student achievement.

This study aims to determine the role of Guided Inquiry in understanding students' concepts in learning the Pythagorean theorem, through student worksheet-based guided inquiry learning models. This study uses descriptive qualitative research methods, which were carried out in class VIII D at SMP Muhammadiyah 1 Gamping. Data collection techniques used were documentation, observation, and written tests. Data obtained in this study were analyzed using data triangulation techniques. The results showed that the Guided Inquiry had a role in helping students to understand the concept of the Pythagorean theorem formula, through several stages of learning. In learning that uses guided inquiry, students can understand the Pythagorean theorem formula by finding it on their own and being facilitated by the teacher. Also, student learning outcomes indicate that the average value obtained by students is above the Minimum Mastery Criteria score for mathematics subjects of 65.

Students who have special needs also have the right to obtain an education as a provision for life, just like regular students. However, several learning tools for them are still very few. It is because some researchers always focus on standard students. Therefore, this study aims to develop visual-based mathematics teaching materials on integer arithmetic operations, one of which is deaf students. The development model used is a modified development model from the 4D model. Teaching materials that have been developed and tested on deaf class VIII students are suitable for use as a learning medium because they meet the criteria of being valid, practical, and effective. Valid because the average value of the three validators is 3.85. Furthermore, the practical standard is because the percentage of the average response score of students obtained is 80%. Finally, the effective criterion is that the average score of students trying to solve the test questions is 81. The results of this study contribute to providing alternative teaching materials for deaf students.

Higher Order Thinking Skills of students in Indonesia, including students in Papua, are still very low. On the other hand, Papua's nature and culture have the potential to be used as an instrument or context in developing questions that can develop students' Higher Order Thinking Skills (HOTS), especially in mathematics learning. This study aims to create and analyze HOTS questions based on nature and culture. The products developed were HOTS items, with the procedure for determining the context, expanding the items, testing the items' validity, and further analysis. The results showed that HOTS mathematics questions could be developed using Papua's Nature and Culture context. These results contribute to inspiring educators and other researchers to establish HOTS questions based on Papua's nature and culture, both in mathematics and other subjects.

This study aims to analyze the mathematics problem-solving process of high school students based on multiple intelligences. In research, multiple intelligence is divided into dominant linguistic intelligence, interpersonal and kinesthetic intelligence, dominant musical intelligence, logical-mathematical and naturalistic, existential, intrapersonal, and visual dominant intelligence. The type of research used in this research is descriptive exploratory, and the approach used is qualitative and quantitative approaches. Determination of research subjects was carried out using purposive sampling based on multiple intelligences, to obtain 3 high school students of class X as research subjects. The research instrument used was a multiple intelligence test and two problem-solving tests adopted from the American High School Math Exam (AHSME) Problems and the Provincial High School Mathematics National Science Olympiad questions. The data obtained were analyzed, utilizing data reduction. The research results show that students with multiple different intelligence bits have different ways of solving them, but there are also similarities in solving problems.

Mathematics is an essential field of science applied in nearly all areas of knowledge and individuals’ daily lives. Therefore, understanding students’ attitudes towards it and affecting their mathematics performance is an essential step for appropriate intervention to make the subject enjoyable. This paper aims to give a comprehensive picture of students’ attitudes towards mathematics and factors that affect their attitude and achievement. To achieve this objective, purposive and random sampling techniques were used. A questionnaire measuring students’ attitudes and their achievement in the subject was distributed to sample students in secondary schools. Data were collected using a questionnaire that was validated, pilot tested, and its reliability was determined. The data were analyzed using descriptive statistics. Students were asked to respond to a 5-point Likert scale questionnaire that includes factors that affect the teaching practice, teachers’ attribution, classroom climate, and students’ concern as a contributing factor for their attitude towards mathematics. Besides, five free-response questions were also included to get an in-depth view of students towards mathematics. Results indicated that students have an almost positive attitude towards mathematics. Factors contributing to poor performance include lack of practice, language deficiency, societal influence, comprehensive content of the subject, lack of background on the course, development of examination in mathematics, absence of tutorial, the need for more recreation, and lack of confidence. Students’ attitude towards mathematics has determined students’ achievement directly as well as the perspective of students, and their achievements are interdependent.

This Qualitative study aimed to describe the students the mistakes in solving the problems related to cubes and cuboid topics based on Newmann's procedures. To gather the data, three students of primary school teacher department in a university in Kupang, Indonesia, with a high, moderate and low problem – solving skills were chosen to be analyzed further using descriptive method. The result showed that the students with a high problem – solving skill were doing wrong in writing the final answer due to an incomplete understanding of cube and cuboid. The students with a moderate problem – solving skill were doing mistake in transforming the word problems into mathematical expression since the students were not accustomed to do non – routine problem. Furthermore, the students with the low problem – solving skills were doing mistakes in transforming word problems into a mathematical expression, during the process and writing the final answer. The mistake was emerged due to students’ inability to understand the problems and incomplete understanding of the concept of cube and cuboid.
