Abstract

Mathematical representation is an idea interpretation form of solving mathematical problems. The process of mathematical representation is essential to pay attention to, especially in carrying out transformations between forms of representation, because it impacts the final solution obtained. This study describes the flow of students' thinking in carrying out the transformation process from visual to symbolic representation. This descriptive research was carried out with a qualitative approach. This research phase includes preparing representation tests and interview guidelines, giving tests to 48 students, conducting interviews with selected students based on the accuracy of the mathematical representations produced, and evaluation. The evaluation is carried out by reducing the results of the incorrect representation test, presenting visual and symbolic representation data and the transformation process, and concluding the transformation process. The result of the transformation process from visual to symbolic representation in solving the problem of the area under the curve is carried out with a flow of thought, namely translating the shape of the polygon area into a collection of rectangles, determining the width and length of the partition of the polygon area, and determining the area of the polygon area as a collection of rectangles. In determining the area as a collection of rectangles, there are two different processes, making a mathematical model in the form of sigma notation and addition. This study provides insight into the flow of thinking in changing between forms of mathematical representation in the hope that it can anticipate errors in solving the broad problem under the curve.

Abstract

The sudden change caused by the global pandemics of COVID-19 leads to the classroom transformation from classical face-to-face meetings into virtual. The development of technology enables classroom variation by providing various applications that can be employed to facilitate learning activities. Nonetheless, not all situations suitable to use advanced technology during distance learning. Some students are living in remote areas with limited internet connection. This study aims to offer an alternative if most of the students were having difficulties with the internet and minimum devices to download heavy applications. The alternative is by using a chat group with an emphasis on the students’ interaction during the lesson. This descriptive study was conducted at a university in Mataram, Indonesia. The subject was 17 students in the Mathematics Education Study Program who follow the course of Abstract Algebra. The data were gathered from students’ observation during the lessons and students’ written work in the middle semester test. The data were analyzed by using descriptive qualitative method. From the analysis, it was found that the students’ activity during distance learning was 83.5%. Furthermore, 88.23% of students achieved the minimum score for the middle semester test (more than 56). The study showed that mathematics teaching and learning could be done with a secure and straightforward access application to gain good results.

Abstract

Indonesia has a diversity of cultures that describes its local wisdom. Culture in certain groups of people or tribes accompanied by mathematical activities was known as ethnomathematics. Ethnomathematics was not realized by the local community because it did not equip with definitions, theorems, or formulas. Therefore, the discussion of ethnomathematics becomes very interesting because it will enrich the treasures of science and also at the same time, preserve culture. One of the cultures introduced in this study is the culture of the Suku Anak Dalam Society (SAD), Batanghari Regency, Jambi Province. The Suku Anak Dalam (SAD) society is a typical ethnic group in Jambi Province. They are classified as ethnic minorities, namely social groups that have weak strength so that they are unable to influence the social system of the people in their territory. However, the SAD society also has ethnomathematics activities that need to be introduced. This research is qualitative research with an ethnographic approach which was analyzed according to Creswell's steps and used ethnographic methods which aim to produce findings in the form of mathematical activities in the Suku Anak Dalam (SAD) Batanghari Regency, Jambi Province.

Abstract

The mathematical connection is a crucial ability possessed by vocational high school students in solving problems by their field of expertise. Agriculture is a field of expertise that requires a lot of mathematical connection skills to solve various problems. Increasing the ability of students' mathematical connections can be facilitated by the teacher by constructing mathematical tasks in the agricultural sector. This qualitative research using the case study method describes the construction of mathematical tasks based on agricultural products and the mathematical connection ability of students in solving the task. Mathematical task construction is carried out by integrating agricultural product contexts and mathematical concepts. The mathematical task was used in Grade X Agribusiness Expertise students of Agricultural Product Processing. Data retrieval of students' mathematical connection abilities was carried out through tests, observation results, answer sheets, and interviews that focused on connecting contexts with mathematical concepts, connections between mathematical concepts, and connections to mathematical procedures. The results of the student data analysis showed that the ability of mathematical connections was hampered by the ability of the connection between mathematical concepts. It is necessary to increase student's mathematical connections by constructing mathematical tasks with various mathematical concepts.
