Realistic Mathematics Education (RME) is a teaching and learning theory in mathematics education that was first introduced and developed by Freudenthal. Two of his important points of view are mathematics must be connected to reality and mathematics as a human activity. RME is implemented following three principles, they are guided reinvention and progressive mathematizing, didactical phenomenology, self-developed model. Furthermore, the practice of RME also has its characteristics, they are phenomenological exploration or the use of contexts, the use of models or bridging by vertical instruments, the use of students own productions and constructions or students contribution, the interactive character of the teaching process or interactivity, and the intertwining of various learning strands. A paper is eligible to be included in this topic if the paper accommodates these three principles and these five characteristics. Educational design research is perceived as the systematic study of designing, developing, and evaluating educational interventions (programs, teaching-learning strategies, and materials, products, systems) as solutions to such problems. It also aims at advancing our knowledge about the characteristics of these interventions and the processes to design and develop them. Authors could submit their work, either a validation study or a development study in mathematics education, with a comprehensive description and analysis of every stage.

Abstract

This study aims to describe the affective assessment of online learning through WhatsApp Group (WAG) media for mathematics students. This study is a descriptive quantitative study. The subjects of this study were 20 students of the Mathematics Study Program, Nahdlatul Ulama University, Purwokerto who had filled out the research questionnaire. This research was carried out in July – August 2021. The instrument used to obtain data in this study was a questionnaire containing 6 close-ended questiouns related to affective assessment in online learning with a Likert scale format distributed via Google Form to 20 respondents. This study used descriptive statistical methods as the data analysis. The study shows that the affective assessment of online learning through WhatsApp Group (WAG) for mathematics students was good according to the data obtained from the students’ answers in filling out the questionnaires. During the online learning process, students are able to pay attention well, understand the material more easily, get assignments and assessments, interact and discuss the material actively with lecturers and fellow students. In addition, students also remain motivated to learn online even though learning cannot be done face-to-face.

Abstract

The purpose of this research is to know the effectiveness of the learning model Problem Posing type Post Solution Posing with Quantum Learning TANDUR type to understand the concept of mathematics on the integral material is not necessarily use three-teir multiple choice diagnostic test based E-Learning class XI MIPA students in SMA N 1 Bringin year Lesson 2019/2020. This research is a quantitative study of quasi-experimental experiments with the design of Posttest Only Control Group design. The samples in this study were students of grade XI MIPA 1 and XI MIPA 2 SMA N 1 Bringin. The instrument used in this study was about understanding the mathematical concept of Three-Teir Multiple Choice Diagnostic Test. The results of the study gained that the classifications of class-savvy category XI MIPA 1 have an average of 26.18% while the class XI MIPA 2 has an average of 21.47%. Thus, understanding the concept of class XI MIPA 1 is higher than the class XI MIPA 2. Then based on the results of the hypothesis test using an average similarity test with test-T scores obtained t-count =-0.00691 is between-2.02 ≤ t-table ≤ 2.02 which means that the effectiveness of implementation of learning model Problem Posing type Post Solution Posing same as the application of learning model of Quantum Learning TANDUR type towards understanding student mathematics concept.

Abstract

The purpose of this study is to determine the difference in the ability of mathematical representation of students students' confidence who use the auditory intellectually repetition learning model with students who use the usual learning model. This research is used quantitative analysis with the Quasi-Experimental Design method. The research design used is a nonequivalent control group design. This study's population was grade VII students academic year 2018/2019. The samples in this study were selected using a purposive sampling technique with grade VII-1 as an experimental class of 30 students and grade VII-2 as a Control class with 30 students. Experimental classes follow learning with auditory Intellectually Repetition models, and control classes follow conventional learning. The research analysis results showed that there were differences in the ability of mathematical representation of students using auditory intellectual repetition learning models with students using ordinary learning models. There is a difference in the confidence of students who use Auditory Intellectually Repetition learning with students who use the usual learning model.

Abstract

The study aims to design mathematics learning in composite function concepts with farm tools, which are thrasher and rice mill machines; this farm’s tool is used as to starting point in the learning process. The research method used is design research with a  preliminary design, design experiment, and analysis retrospective stages. This study describes the design of the thrasher and rice mill machine to facilitate a real contribution for student understanding of the composite function concept. The participant of this research is 10 eleventh-grade students from one of the senior high school in East Java. The results of this study reveal that students are able to make associations from the thrasher and rice mill machine through the determination of the input and output of the machines to the formula of the composite function concept. So, the stages in the learning trajectory have an important role in understanding the composition function concept from informal level to formal level and also make the study of mathematics more easy, simple, fun, and comfortable.

Abstract

Mathematics is one of the basic concepts needed by students at every level of education. However, students often have difficulty in understanding mathematics. This can be seen from the mistakes made when working on math problems. Errors made by students must be addressed immediately so that no more errors occur, especially on questions that have the same characteristics. The purpose of this study was to determine the percentage of conceptual errors, arithmetical errors, writing errors and the most common mistakes made by students on the subject of exponential and logarithmic equations. Sampling was done by using purposive random sampling technique. The data in this qualitative descriptive study were collected using test, interview, and documentation techniques. The instrument used to collect data was in the form of test questions and interview guide sheets. The data were analyzed by categorizing the types of errors into conceptual errors, arithmetic errors, and writing errors and then calculating the percentage of errors in each category. The results showed that the errors made by students in each category were conceptual errors of 53%, arithmetical errors of 34.78% and writing errors of 28.99%. The error that many students make is a conceptual error as much as 53% with a moderate error percentage category.
