“…However, the concepts applied in the modeling process carried out by children using units of foot or wood are the rules that they make according to their needs. These rules, therefore, do not give them proper restrictions, in contrast to school mathematics, which imposes precise restrictions on the use of rules (Osterberg & De Lara, 2019;Sumarsih et al, 2018). Through games, children's incredible capacity for modeling or symbolization gives them a powerful tool to understand their environment and create and organize environmental events that touch almost every aspect of their lives later in life.…”

Each culture has its own mathematics, and mathematics is born of culture. And ethnomathematics exists as a link between mathematics and culture. This study aims to analyze the ethnomathematics contained in the soccer game of Aceh's coastal children. This type of exploratory research uses an ethnographic approach. The subjects in this study were Acehnese coastal children aged five to twelve years who were playing ball in the afternoon, totaling 18 people. The selection of the subject of the study was carried out using the incidental sampling technique. Data collection is carried out through observation, interviews, and documentation. There are four forms of data analysis in this study such as domain, taxonomic, component, and cultural themes. The results of this study show that children, while playing, have used knowledge in mathematics, such as the concepts of line alignment, addition and difference, comparison, the theory of opportunity, numbers and rounding, and measurement, without realizing it. In addition, the mathematical concepts used in football games show that Acehnese coastal children have their own ethnomathematics, as evidenced by their being able to do mathematical modeling, understand the concept of harmony, and argue. So that ethnomathematics in the soccer game of Aceh coastal children is shown in the form of mathematical behavior that reflects children's understanding of problems and how to solve them using mathematics.

“…This can be interpreted that mathematical reasoning skills need to be developed. However, there have been many research results showing that students' low mathematical reasoning was caused by the teacher only providing the subject with examples and routine problem exercises, but when given non-routine questions, students experienced difficulties when they had to start determining the solution (Fuadi et al, 2016;Indriati, 2018;Izzah & Azizah, 2019;Napitupulu et al, 2016;Nasution et al, 2019;Putri et al, 2019;Zubainur et al, 2020). Material that concentrates on non-routine problems is found in material on trigonometry.…”

Objective: To get around students' reluctance, learning media is needed; one of them is the development of mathematics teaching materials. The development of teaching materials is needed to actualize subjects, especially mathematics, as a contextual subject. This goal is to improve students' reasoning abilities in understanding and solving the problems in daily life. The function of the model is as an intermediary between students' mathematical reasoning abilities and the questions presented in the development of teaching materials. More mathematical reasoning abilities are found in trigonometry material. Trigonometry is the science of measuring the angles and boundaries of triangles (used in astronomy and so on) in which there are solutions for other problems, such as measuring the height of mountains, buildings, towers, etc. Method: This research uses a qualitative method. Results: The teaching material Trigonometry research is valid for module material validation, graphics or media validation, and obtained from audience validation results. The three percentages are at a very valid validation level and can be used in schools. Novelty: After the application of this teaching material, the result was that students' mathematical reasoning abilities became better.

“…Furthermore there are four factors of the importance of reasoning in daily life, such as (1) reasoning is needed in solving mathematical problem, (2) reasoning is needed in learning mathematics in school, (3) reasoning can be implemented in any other knowledges or sciences, and (4) reasoning is needed in daily life [13]. Reasoning is one of the crucial abilities in mathematics as a supporting feature in mathematics learning [14] [15]. Therefore, mathematical reasoning is one of the important abilities for the students in any level of the education, especially in high school level.…”

Mathematical reasoning is one of the abilities that must have by students after learning mathematics. To improve students’ reasoning, teachers also have to good in reasoning. Due to the importance of reasoning for teachers, a qualitative descriptive research was conducted to analyze how the reasoning of preservice mathematics teachers in solving critical thinking problem. The data were collected through instrument test that consists of one problem about perimeter of a rectangle from 40 preservice mathematics teachers of first year in one of public universities in North Aceh, Aceh, Indonesia. The problem measured the skill of manipulating mathematical process; constructing mathematical proof, and drawing conclusion. Their works were analyzed for each indicator of reasoning. The result showed that more than 75% preservice mathematics teachers were wrong in solving the problem. They were not good in constructing mathematical proof to draw a conclusion. It concludes that preservice mathematics teachers’ ability in mathematical reasoning was not satisfied. The ability still needs to be improved through learning activities and they must be accustomed to the problems or situations that involving reasoning
