This study aims to determine the suitability of mathematics textbooks for eighth-grade with Trends in International Mathematics and Science Study (TIMSS) 2019 Mathematics Framework. This research uses a qualitative research method with a descriptive approach and content analysis techniques. The data of this research are the eighth-grade mathematics textbook. In the textbook analysis, the researcher used three textbooks, namely Penerbit Erlangga, Yudhistira, and the Ministry of Education and Culture (Kemendikbud).

In traditional teaching, many teachers often ignore the process of students' knowledge exploration, devote themselves to instilling knowledge to students in a short time, and then adopt the sea of questions tactics. Such teaching is only limited to the stage of telling students what "variance" is and how to use it, and ignores the birth process and meaning of "variance". The purpose of this research is to see the differences in classes that use dynamic mathematics software and traditional classes. The method in this research is descriptive qualitative.

This study aims to analyze students' mathematical connections in terms of their initial ability to material opportunities. This type of research uses a quantitative approach with a quasi-experimental method with the design of this research is the Two Group Pretest-posttest. The population of this study was all students of semester VI Physics Tadris UIN Sulthan Thaha Saifuddin Jambi, totaling 42 people. The sampling technique used was saturated sampling with research instruments in the form of test descriptions. Data were analyzed using a paired t-test test.

This study aims to examine the difference in Realistic Mathematics Education (RME) increase with students who obtain Autograph assisted discovery leaning, 2.The interaction between learning models and students initial mathematical abilities to students’ mathematical problem solving abilities. This type of research is quasi-experimental. The population in this study were all the students of class IX SMA Alwashliyah 3 Medan totaling 90 students. The sample selection is determined by randomly selecting two classes.

This study aims to determine (1) the mathematical fluency procedural ability of students taught using the peer lesson learning model and those not taught with the peer lesson learning model in class VIII, and (2) the effect of the peer lesson learning model on the mathematics procedural fluency ability of grade VIII students .

The purpose of this research is to test effectivitytrategy Think Talk Write (TTW) of the ability of problem solving mathematical, and test whether the differences efektivity between strategy Think Talk Write (TTW) with determine saintific of the ability of problem solving mathematical students. The kind of research this quasi his experiments with design research posttest only control group design. Population in research it is a whole students grade VIII of SMP Negeri 34 Batam which consisted of 279 students which are divided into 7 class.

The students’ difficulties on understanding the material and the lack of the enthusiasm in learning mathematics, especially in angle measurement material were be the basic reasons for this research. In addition, conventional learning methods that characterized by lectures were still often used by teachers in learning. Therefore, the learning not being more active, effective, and enjoyable. The development of educational learning media like analog clock board was one of the solutions to improve students’ understanding.

This study aims to determine the effect of blended learning strategies on the creativity of the pre-service teachers. By a quantitative approach, the type used in this study is a quasi-experimental with pretest-posttest control group design. The population in this study were pre-service teachers in semester VII of the Mathematics Education Study Program at Universitas Negeri Medan. The instrument has used a test in the form of essay tests of 5 items concerning creativity.

This study aims to describe the students’ mathematical connections in terms of the locus of control. The mathematical connection indicators in this study are writing down the mathematical concepts that underlie the answers, recognize the relationship of various mathematical ideas and mathematical topics that can be related to problems of everyday life, and understand how to solve mathematical ideas that are interrelated and underlie each other to obtain an integrated whole. Data collection methods in this study were questionnaires, tests, and interviews.

This study aims to determine the difference of students’ representation ability through the Augmented Reality (AR) and kinetic sand as learning media. This research is a quasi-experimental by nonequivalent control group design. The students’ representation ability compared based on students’ prior mathematical ability (PMA) as high, medium, and low category. The data analyzed by using two path Anova on SPSS 16. The results of data analysis shown that there is no difference on students’ representation ability in both AR class and kinetic sand class in significance value of 0.68.
