The ability to think mathematically is very important for students to solve problems in everyday life. However, in reality, many students cannot find concepts, reason, problem-solving, communication, and connect mathematics to other sciences. This happens because students are not able to understand abstract mathematics. Teaching materials are needed in the form of applications on the device so that they are attractive to students. The ethnomathematics mobile module is a teaching material that contains mathematical material that is brought closer to everyday life through ethnomathematical learning. This study uses research and development (R&D) methods with the Borg & Gall model which is adapted from Sugiono's development model. The data of this study were obtained from a validation questionnaire of material experts and media experts. The type of data produced is qualitative data which is analyzed with assessment criteria guidelines to determine product quality. The purpose of this study is to obtain an ethnomathematics mobile module design to facilitate valid mathematical thinking skills. Based on the results of the assessment from the validator, the average value of the ethnomathematics mobile module material validity test was 3.76 (very valid) by material experts and the validity of the ethnomathematics mobile module media was 3.80 (very valid) by media experts. These results indicate that the ethnomathematics mobile module that was developed is valid or feasible to use.

Mathematical literacy is essential because it can reason mathematically and formulate, apply, and interpret problem-solving in various everyday contexts. Following the PISA study, which assessed students aged 15 years with the age of high school students, this study aims to determine the reasoning ability of high school students in solving mathematical literacy problems. The method used in this research was descriptive qualitative. The research subjects were 22 students of class X, one of the private high schools in Pangkalpinang. Data collection techniques were written tests and interviews. The test instrument consisted of 10 items of developed mathematical literacy questions that meet the criteria of being valid, practical, and potentially affecting students' reasoning abilities. The questions were developed using the Bangka Belitung context. The students' answers were assessed based on a scoring rubric through primary mathematical skills of reasoning and argument indicators. Meanwhile, interviews were conducted with six students using the purposive sampling technique with high, medium, and low reasoning abilities. Interview data were used to dig deeper into students' reasoning abilities when solving the problem. Data were analyzed based on the percentage of students' mathematical reasoning abilities indicators, including data reduction, data presentation, and concluding/verification. The analysis results found that students' reasoning abilities mastery was very low on all indicators. At the indicator proposing allegations, mathematical manipulation, compiling evidence and reasons, it reaches a level of 42.88%, while at the level of mastery, the indicator concluded statements of 41.36%. The causes of students' difficulties in bringing up reasoning abilities included students who were not accustomed to solving questions that required high reasoning abilities. For example, mathematical literacy questions that were done and lack of mastery of mathematical concepts that had been studied made it challenging to bring up reasoning abilities.

Mental retardation certainly has a different thought process from other normal children. Because it is different, there needs to be a study of the thought process with the aim of finding a solution to overcome the problems that are often faced by mentally retarded students in learning mathematics. The purpose of this study was to describe the thought process of mentally retarded students in understanding geometric concepts based on Piaget's theory. The subjects of this study were two mentally retarded students who were in class VI. The stages of the research carried out were carrying out a learning process for three consecutive days to recognize geometry using visual aids then at the end of the activity, mentally retarded students were given evaluation questions in the form of make a match. The results showed that the two mentally retarded students experienced disequilibrium several times until they finally experienced the process of assimilation and accommodation. However, only one student experienced equilibrium who was able to connect flat figures and spatial figures based on the results of their observations. The learning process for mentally retarded students must be repeated until they arrive at an understanding of mathematics.
