The journal invites original research articles and not simultaneously submitted to another journal or conference. The whole spectrum of research in mathematics education are welcome, which includes, but is not limited to the following topics: Realistic Mathematics Education (RME) 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 views are mathematics must be connected to reality and mathematics as human activity. RME is implemented following three principles, they are: (1) guided reinvention and progressive mathematizing, (2) didactical phenomenology, and (3) self-developed model. Furthermore, the practice of RME also has its own characteristics, they are: (1) phenomenological exploration or the use of contexts, (2) the use of models or bridging by vertical instruments, (3) the use of students own productions and constructions or students contribution, (4) the interactive character of the teaching process or interactivity, and (5) 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. Design Research in Mathematics Education 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. Mathematics Ability Mathematics ability refers to the ability (a human construct) to obtain, to process, and to retain mathematical information (cognitive) and to solve mathematics problem (pragmatic). To maintain the focus of this journal, the scope of mathematics ability includes the following abilities: reasoning, connection, communication, representation, and problem-solving. A paper is eligible for this topic if it comprehensively discusses those abilities.

Abstract

This study aims to determine whether applying the Make A Math type of cooperative learning model can improve student learning outcomes in mathematics. The type of research used is Classroom Action Research. The sample in this study were all students of class VIIC SMP Negeri 7 Kebumen, totaling 24 students. The instruments used in this study were observation, documentation and tests Based on the results of the study, it was concluded that the application of the Make A Math type of cooperative learning model could improve student learning outcomes in mathematics class VIIC at SMP Negeri 7 Kebumen. The increase in student learning outcomes can be shown in the results of the final cycle test after applying the Make A Math type of cooperative learning model, the class average score was obtained with the results in the pre-cycle of 57.70; cycle I amounted to 67.08 and cycle II amounted to 78.95. With a percentage of completeness in the prasilkus of 33.33%, in the first cycle as many as 11 students completed with a percentage of 45.83% and in the second cycle there were 18 students who completed with a percentage of 75%

Abstract

At the time of the Covid-19 pandemic, all learning was carried out online or online learning, while schools and students had to follow the existing curriculum in their schools, which of course not all of their lessons were happy. Mathematics is one of the subjects that is always a scourge for students, regardless of those who enjoy mathematics. The reasons vary, some say the lessons are difficult to understand, students are not interested in learning mathematics, the teachers are boring, and so on. So that many parents of students who provide additional tutoring for their children by hiring math teachers, in the hope that their children are mathematically intelligent. This study aims to examine the effect of using animated interactive multimedia on students' understanding of the concept of understanding mathematical concepts. The population of this study were students of class VII MTs Darul Ulum Muhammadiyah Galur even semester of the 2019/2020 school year. Of the five existing classes, two classes were taken randomly as samples with one class as the experimental class and one class as the control class. This study used the randomized pretest-posttest control group design. The research data were obtained through a test in the form of a description of the rectangular and square material. The results showed that there was a difference in the understanding of mathematical concepts in students who used animated interactive multimedia higher than the understanding of mathematical concepts of students who took conventional learning, and there was a positive and significant effect of the use of animated interactive media on the Mathematical Concept Understanding of Class VII MTs Darul Ulum Muhammadiyah Galur Tahun Students 2019/2020 Teaching

Abstract

This article examines the estimation of spline regression, especially its use in longitudinal data. Longitudinal data is data obtained based on observations made as many as n objects that are independent with each object being repeatedly observed in different time periods and between observations in the same object are dependent besides longitudinal data is data that can distinguish the diversity of responses caused by The regression curve of the spline was estimated using the least squares. It can be seen that the estimation of the spline regression curve for longitudinal data is a class of linear estimation in response observations and is highly dependent on the knots point k1,k2,...,Kn

Abstract

Classroom action research was motivated by the less active attitude of the Class V students of MI Negeri 4 Gunungkidul. located in MI Negeri 4, located in Dusun Semenrejo, Pulutan Village, Wonosari District, Gunungkidul Regency in learning mathematics. The Snowball Throwing learning model is expected to be able to improve it, especially in the material of addition and subtraction of fractions with different denominators on. This research was conducted during July 2019. Data was collected through observation, interviews and documentation. The research was carried out for two sessions continuously to produce according to expectations where the achievement was achieved through learning as many as 22 students. Therefore it is suggested that the teacher can apply the SbT type of cooperative learning model to other materials. Variations can be made within the framework of cooperative learning that is adapted to the material and conditions

Abstract

Mathematics education is one of the fields that agrees about the importance of integrating technologies into instructional activities in the classroom. However, only understanding technologies does not full fill the criteria of effective teachers, they have to be prepared and grasp the ideas of combining technologies, pedagogical, and content knowledge. This present study is a literature review which aimed at answering two mains questions namely, what is the TPACK framework and how does it influence our education system. Data were collected from articles related to technologies, ICT, and TPACK from thematic journals. The results found that TPACK is a well-known theoretical approach studying the pre-service teachers’ use of ICT. TPACK is accepted as an important framework for defining how well teachers integrate technologies in their classroom. TPACK model shows an effective way of thinking about integrating technologies along with pedagogies, and content knowledge. It has been developed for twenty-first century skills and used as a framework for developing teachers’ readiness toward the twenty-first century skills.
