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

We attempt to study the evolution of the sickle cell anaemia in the region of Kinshasa by proposing three models based on Markov processes.  The first two models namely, the idealistic and the quasi- idealistic models fail to completely describe the data sampled. The third model, the realistic one, leads to results that match the data collected and meets the predictions of serious institutions such as the World Health Organization (about 36 percent of the population belongs to the electrophoresis categories AS or SS).

Abstract

Student learning styles affect the problem-solving abilities. Therefore, further studies on student learning styles are needed regarding problem solving abilities. This research aims to analyze students' problem-solving ability with assimilator learning styles. This research is qualitative research using descriptive method. The subjects of this study were two students of class XI MIPA 1 SMA Adhyaksa 1 Jambi City. The students in question are students with assimilator learning styles. The instruments used were Kolb's learning style questionnaire, mathematical problem-solving ability tests, and interview guidelines. Based on the results of tests and interviews on the subject, it was found that, in general, not all indicators of problem-solving abilities can be met by students with assimilator learning styles. However, they are good at formulating, planning, and implementing problem solving. However, not by checking again. In formulating the problem, students do not write it on the answer sheet but can explain it well during the interview. The tendency of students to solve problems theoretically causes students to have difficulty when they do not know the formula to solve the problem.

Abstract

Computational thinking skills are a relevant approach to future problem-solving. Therefore, these skills need to be integrated into mathematics learning in schools. This research is part of developing mathematical computational thinking skill tests for junior high school students. In this segment, the study aims to analyze the content validity of the mathematical computational thinking skill test. The main stages in this research are define, design, and develop. Expert validation data were collected using Google Form sheets. The analysis technique used is the content validity technique with the V Aiken method.  The results of the study revealed that the results of content validation through the assessment of 7 experts, developed a test specification containing 20 items that measure mathematical computational thinking skills with a coefficient (V) in the interval (0.770 – 0.920) with an average of 0.866 or very good category. The test instrument is valid for measuring decomposition indicators, pattern recognition, abstraction, algorithmic thinking, and evaluation indicators. Each indicator is measured by 4 items with a coefficient of V decomposition indicator of 0.868, pattern recognition 0.883, abstraction 0.865, algorithmic thinking 0.833, and evaluation 0.883. The study concludes that the indicators of decomposition, pattern recognition, abstraction, algorithmic thinking, and evaluation indicators are valid in measuring mathematical computational thinking skills.

Abstract

Justification is a set of responses or responses that a person gives when asked to provide mathematical reasons for the results he makes. Justification can be used as a social process in which mathematical knowledge is explained, and systematically verified based on ideas, definitions, and properties that apply in mathematics such as representations used to display concepts. Research on justification in mathematics education has been carried out for a long time. This study aims to evaluate mathematics justification studies from articles published after 2016 and before April 2022 from ERIC and Google Scholar Databases. The key questions in this study are how these articles are distributed based on year publication, country, participant, mathematics subject, method, and how to support mathematical justification. This study used a Systematic Literature Review (SLR) by Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines including inclusion and exclusion criteria and then the data were extracted, resulting in 30 studies to be reviewed. The result shows that by year of publication the articles fluctuation distributed, based on country no data from Africa and Australia was found in the databases, the participant is mostly preservice mathematics teachers, whereas only one publication studied in high school students, geometry is the most mathematics subject used in research since every grade contain this material, the method is frequently given by qualitative research with various approach, how to supporting mathematical justification is also discussed.
