Authors:mitra permata ayu Abstract: Perception is an individual's ability to respond, interpret, and distinguish a view of any information to a stimulus. So the aims of this study was to find out: (1) students' perceptions of the use of an equation editor in writing mathematical notation as assignments for calculus class I papers, (2) students' perceptions of writing calculus I paper assignments using the manual method (handwriting). The research subjects consisted of 16 students majoring in Extension Informatics Engineering (afternoon class) Semester I. The type of research was descriptive qualitative. Data collection techniques are interviews. The analysis stage is to analyze the results of the interviews. The results of the study concluded that: (1) 11 (eleven) students agreed to use the equation editor in writing calculus I paper assignments,the rest were still confused about the use of the equation editor; and (2) all students do not agree if the paper is written using the manual method (handwriting) because the results are not neat and take a long time.

Authors:Widiya Astuti Alam Sur Pages: 21 - 32 Abstract: The aim of this paper is to present the statistical model simmulation about the definite integral concept based on upersum and lowersum random partitions by using geogebra. The random partitions of the uppersum and lowersum in determine the value of definite integral is used to find out the statsitical distribution of its generated random variable. Based on Kolmogorov Smirnov Test, the random variable data of subinterval partitions on uppersum and lowersum by using goegebra followed the certain statistical distribution. The random partitions of uppersum and lowersums followed Burr 4 parameter, Log-Pearson 3, and Pearson 6 distributions. PubDate: 2022-03-20 Issue No:Vol. 6, No. 1 (2022)

Authors:Faradiba Jabnabillah Pages: 33 - 44 Abstract: The ability to understand students' concepts is very important to be applied to learning mathematic. When students cannot understand the concept well, students will not be able to solve the problem correctly. This is the reason the researcher conducted this research. The purpose of this research is to describe student errors in solving problems of understanding the concept of integral material. The subjects in this study were class XII students of SMK N 4 Batam. The data collection technique used a test to see student errors in answering questions of understanding the concept. This study uses a qualitative approach with a descriptive type of research. The results obtained in this study are the indicators of reading errors about getting a percentage of 62,5%, then the percentage of errors in understanding the problem gets a value of 50%, the percentage of transformation errors gets a value of 75%, then on the percentage of process skills errors it gets a value of 62,5%, and the percentage of errors in writing the final answer also gets the same result as the percentage process skill error that is equal to 62,5%. This is because most students do not understand the integral concept so they do not understand in determining the formula and applying it. PubDate: 2022-03-20 Issue No:Vol. 6, No. 1 (2022)

Authors:Nuzul Putri Rahmawati, Moh. Asikin, Mariani Scolastika Pages: 54 - 69 Abstract: The purpose of study to described student’s literacy analysis using Self-Organized Learning Environment (SOLE) learning model. The low student’s statistical literacy ability as one of the abilities needed facing problems in today’s society. Therefore, the problem became background of this study. By utilizing Internet accessibility and the environment in the Self-Organized Learning Environment (SOLE) learning model, it was possible for authentic learning and twenty-first century development skills to mature. This study used to Self-Organized Learning Environment (SOLE) learning model, which students self-organized in groups and learned to use computers connected to the internet with minimal teacher support. This study also used mix methods. Students' statistical literacy ability using the Self-Organized Learning Environment (SOLE) learning model was analyzed by descriptively. The result of study was a statistical analysis of the literacy of 32 students with the following details: 28.125% of students had statistical literacy in the high category, 40.625% students had statistical literacy in the medium category, the remaining 31.25% students were in the low category.

Authors:Himaya Agustin, Dwi Priyo Utomo, Adi Slamet Kusumawardana Pages: 70 - 80 Abstract: At this time, many students think that learning mathematics is difficult to understand. While Powtoon animation video-based mathematics learning media is still rarely applied, students feel bored. They do not understand the concept of material when the learning process uses the lecture method. The purpose of this study was to determine the effectiveness of using Powtoon animation video-based mathematics learning media on the material for the Two-Variable Linear Equation System in Junior High School. The type of approach used is a pre-experimental quantitative approach by applying a one-group pretest-posttest design. The research population includes all students of class VII-A at SMP NEGERI 1 NGIMBANG for the academic year 2020/2021, with 32 students consisting of 8 male students and 24 female students. Data collection techniques using tests and questionnaire sheets. While the data analysis technique used is normalized gain. The data obtained show differences in students' test results using the Powtoon animated video and before using the Powtoon animated video. The difference was seen from the average score of the students' test results before using the media of 36.41 and after using the media of 92.58. In addition, the research results from the N-Gain Test results show that the use of Powtoon animation video media is effective in learning mathematics. It is evidenced-based on the results of the expert test and media validation by obtaining 85% and 83.75%, which means that it belongs to the outstanding category. In comparison, the results of the student response questionnaire of 81.29% belong to the outstanding category. Students' test results get an average of 0.88% from the n-gain, which shows a high classification. This study indicates that Powtoon animation video media is effective in learning mathematics compared to learning that only uses the lecture method. 29% of it belongs to the outstanding category, then through the test results, students get an average of 0.88%, which is obtained from the n-gain, which means it shows a high classification.

The relationship between students' learning motivation and mathematics learning is that the more media used by the teacher, the higher the learning motivation PubDate: 2022-03-20 Issue No:Vol. 6, No. 1 (2022)

Authors:Fransiska Dwi Lestari, Ali Syahbana, Allen Marga Retta Pages: 104 - 117 Abstract: One of the mathematical abilities that students must master in order to learn mathematics is the ability to understand concepts, since it can affect the quality of learning and academic accomplishment of students. If the student's idea understanding is good, he or she will be able to solve the problem using the procedure. As a result, the goal of this study is to determine and describe students' grasp of mathematical ideas in linear programming material. This study's instrument is a set of learning outcomes test questions that refer to indications of concept comprehension. A qualitative research design is used in this study. Data reduction, data presentation, and generating conclusions were used to examine the data in this study. According to the findings, 33 students were able to meet the indicators of the ability to understand mathematical concepts by providing examples and non-examples, which received the highest percentage value, followed by indicators presenting concepts in various forms of mathematical representation, which received the second highest percentage value.
