Abstract

Mathematics is an essential subject for students. Teachers, therefore, need to provide innovative learning that develops students' mathematical skills. This study was conducted to determine the effect of a problem-based learning (PBL) model on students' mathematical representation competencies, self-confidence, and habits of mind. It used a quantitative methodology and was conducted on eighth-grade students divided into an experimental class with a PBL model and a control class with a direct learning model. The results showed that the mathematical representation competencies of the students in the experimental class were better than those in the control class. Students' self-confidence and habits of mind also influenced their mathematical representation competencies. It shows that the PBL model positively affects students' mathematical representation competency, self-confidence, and habits of mind. Teachers can use the PBL model to develop their students' mathematical representation competencies by paying attention to students' self-confidence and habits of mind.

Abstract

. Lesson Study (LS) is the learning of assessment activities carried out by a group of teachers / faculty collaborative and sustainable to test and improve the effectiveness of learning. In this study, the implementation of lesson study to improve student interest in learning through the learning method Seminars Group. The results obtained by analysis of the average increase student interest in learning. Cycle 1 gained an average interest of students 67, 86 in the category of high interest in learning. In the first cycle of the findings of the observer focused on seating position make it difficult for the observer to move and students still do not concentrate on learning. Seat that is positioned in groups. Cycle 2 gained an average of 70.78 in the category of student interest high interest in learning. In Cycle 2 focused on the position of the seat. Apparently after the seat is positioned to the observer, the motion less students, so many students are easily sleepy and easier to jaw, with no attention to the lecturer. Cycle 3 gained an average of 72.59 students' interest in the category of high interest. In the do cycle 3, the observer gain some findings that many students were late, and there are still some students who own story. This is possible because they are too short presentation and question focus. Suggestions observer, lecturer models the moderator in the learning process. Cycle 4 gained an average of 72.71 in the category of student interest high interest in learning. Learning is in conformity with the plan, but there are still students who do the work of other subjects. This is a model professor responded by asking questions that make students think, re-concentration of students with learning again.

Abstract

Project-based learning is one of the 21st-century methods that can increase the students' ability to have useful competence in their knowledge, especially in learning mathematic. Hence, the teachers' perception of the implementation of PBL is essential to know. The purpose of this study was to determine student perceptions about the application of project-based learning models. This research is a survey research with a quantitative descriptive approach. The samples used in this study amounted to 63 students of the sixth semester in the Department of Mathematical Education, Muhammadiyah University North Sumatra. The data collection technique used a questionnaire. The data analysis technique consists of quantitative analysis techniques with a statistical approach. The results of this study indicate that: (1) the students' perceptions of the interaction aspects of students and teachers are in the very good category with a mean score of 85.32%. (2) Students' perceptions of motivation / increasing student interest in learning are in the very high category, with an average score of 85.53%. (3) Students' perceptions on the competency aspect of understanding subject matter are in the very good category with an average score of 85.48%. (4) Students' perceptions of the competency aspects of critical, effective, and efficient thinking are in the category of strongly agree with a mean score of 82.62%. (5) Students' perceptions of good time management competence are in the good category with an average score of 79.10%. (6) Students' perceptions of good student learning outcomes are in the very good category, with a mean score of 82.67%. (7) Students' perceptions of the learning model's conformity aspect with subject characteristics are in the very high category with a mean score of 84.05%.

Abstract

This study aims to determine the online learning interactions carried out by junior high school teachers in the classroom during the COVID-19 pandemic. The quantitative using survey was used as a research methodology. 141 Mathematic Teachers was selected as the subject of this research. A questionnaire of classroom interaction practice in an online class was used as a data collection technique. The result found that mathematic teachers’ interaction activity in online courses has a different level. The interaction process that mathematic teachers use is in preparing the students to join an online course and leading the discussion with the mean of 4.2 and 4.3. In contrast, the lowest interaction happens in interaction in giving feedback and interaction in closing activity with an average of 2.5. the research also found that 78.70% of mathematic teachers always provide direction to the students in starting the online class. 40.30% of them never ask students to correct incorrect assignments during online learning.

Abstract

Ethnomathematics is the finding of mathematics in the cultural values of a place. Indonesia has many kinds of cultures, and ethnomathematics research has been done in some areas of Indonesia. This study aims to identify the cultural forms and mathematical materials found in ethnomathematical research in Indonesia. The research method used is a literature review. The stages of the research method included selecting a topic, developing tools of argumentation, searching the literature, surveying the literature, critiquing the literature, and writing the thesis. The instruments used were Google Scholar, the search engine, and the NVivo application. The number of articles analyzed was 88 articles. These articles represent the culture spread across 34 provinces of Indonesia. The research results obtained are cultural forms containing mathematical material, including ideas, activities, and artifacts. Mathematical materials explored in these cultures include statistics, trigonometry, vector, algebra, arithmetic, one-dimensional geometry, two-dimensional geometry, three-dimensional geometry, coordinate geometry, transformation geometry, calculus, logic, and opportunity. The complexity of the culture and material found in mathematics shows that ethnomathematical research can be developed in all forms of culture and applied in various mathematics learning materials.
