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

AbstractThis thesis discusses the effectiveness of applying the Realistic Mathematic Education (RME) Approach and Classroom Assessment to the learning outcomes of Class V students on cuboids material in MI Miftahul Ulum I and II in the academic year 2019/2020. This study is motivated by the lack of students' understanding of mathematics which is basically closely related to the real things that are around. From the research that has been carried out regarding the effectiveness of the application of the Realistic Mathematic Education (RME) and Classroom Assessment approach to Mathematics learning outcomes of the subject matter of cuboids material of students in class V MI Miftahul Ulum I and II Honggosoco in the academic year 2019/2020, the research was conducted using the method experiment and it can be concluded that, based on data analysis and discussion stated earlier in chapter IV and also based on the average test of one party, then the analysis of learning outcomes based on the average difference test of one party is obtained = 3,832 dan = 2,011. Because tcount ttable, then it is significant and the proposed hypothesis can be accepted. The average learning outcomes of students given teaching by applying the development of a Realistic Mathematic Education (RME) approach and Classroom Assessment is better at 66.64 compared to the average learning outcomes of students given teaching using conventional learning that is 54.92.

Abstract

The background of the research is based on the fact that problem solving skills and its process is still low so that those create overload information. Another way to overcome this problem is to use a problem-based learning model which concerns on cognitive load theory. This study is aimed to determine on how students' problem solving skills when using a problem-based learning model modified by cognitive load theory. This research method uses a combination of research methods, namely quantitative as primary data and qualitative as secondary data. The population in this study are all students of grade VII Junior High School accredited A in Tangerang Regency. The sampling technique used is cluster random sampling and the selected sample is 60 students of Grade VII SMP Negeri 3 Cikupa which divided into experimental class and control class. The instruments in this research are 5 short essay tests and non-tests, questionnaire and interview. Based on data analysis’ result, it can be concluded that the achievement and improvement of students' mathematical problem solving abilities which use problem-based learning model modified by cognitive load theory is better than for those using problem-based learning generally.

Abstract

The purpose of this study is to determine mathematical communication skills that assessed from introvert and extrovert personality types, to determine the strengths and weaknesses of each personality type. This research is a qualitative descriptive study. The class subjects are students of SMA Kartika III-1 Banyubiru, grade XI MIPA 2 (Mathematics and Natural Science). The subjects of the research are 2 introvert and 2 extrovert personality types' students. The procedures of collecting data are written tests, interviews, questionnaires and documentation. The results of this study show that mathematical communication skills in terms of introvert personality type are able to meet 1 indicator. That is the ability to explain ideas, situations and mathematical relations in writing. In contrast, the extrovert personality type meets 2 indicators of mathematical communication skills. There is the ability to express daily events in language or mathematical symbols and the ability to read mathematical symbols. The strengths of introvert personality type are able to explain ideas verbally and in writing. Then the weaknesses are difficult to understand the problem of mathematical images and symbols. In contrast to the introvert, extrovert personality's strengths are able to understand mathematical symbols, and then its weaknesses are hard to understand mathematics questions.

Abstract

During the current Covid-19 pandemic, the learning system in all educational institution is shifted from face to face to online learning, including universities. This study aims to describe the results of the mathematical communication skills of class B students of Mathematics Education from Ahmad Dahlan University for the 2019/2020 academic year during online learning during the Covid-19 pandemic and to examine students' mistakes in solving differential calculus problems regarding the minimum, maximum material. This study employed descriptive qualitative research. The research instrument used is a test and interview guide. The data are collected using tests and interviews. The research subjects were selected by stratified random sampling technique so that 6 students are classified into high, medium and low categories. The questions are in the form of a description of one question with six questions. The results showed that students' mathematical communication skills on indicators (1) restating information was done appropriately, (2) writing down ideas or problem-solving steps clearly and precisely, some were not thorough, (3) presenting information using graphic images again. There are still things that they couldn't understand and (4) Writing down the answers according to what is known and are asked using mathematical formulas, some are still wrong because they are not accurate.

Abstract

The purpose of this study was to improve students' problem-solving abilities using the Team Assisted Individualization (TAI) model in students grade IV of Bekasi Jaya II State Elementary School. This study was carried out because of the students' low problem-solving ability in Mathematics.This study employed the Classroom Action Research approach, which was conducted in two cycles. Each cycle has four stages, namely, planning, implementation, assessment, and reflection stage. About 27 students from grade IV has participated in this study. Data collection was carried out through written tests and observation sheets. Data were analyzed with descriptive analysis. The criterion for success in this study is if 80% of students achieve a minimum score of 75.Based on the results, the students' problem-solving ability in cycle I with classical completeness was 59%, and got an average score of 72. In cycle II with 89% classical completeness, and the mean score of students' problem-solving abilities increased to 88. Thus, it can be concluded that the Team Assisted Individualization model can improve the conceptual understanding of grade IV students of Bekasi Jaya II State Elementary School.
