Realistic Mathematics Education (RME) has gradually influenced the development of mathematics learning worldwide, including in Indonesia. Through the implementation and development of online-based 21st-century education, RME is increasingly proving itself as an effective approach to improving the quality of mathematics teaching and student learning. Learning using the RME approach based on the e-module System aims to become a real learning experience for education and students in implementing mathematical concepts into web-based software systems. The type of research used is pseudo-experimental research with a population in this study of 3 schools, and the number of samples is 147 students. Hypothesis testing was carried out with the N-gain test on the experimental class and control class and the Linear Regression Analysis Test to determine the effect of Gender on improving the learning outcomes of the experimental class. The results of this study show that: 1) There is a difference in the improvement of learning outcomes of classes taught with the RME approach based on the e-module System with conventional learning models; 2) There is no significant difference in the improvement of learning outcomes of students taught using the RME approach based on the E-Module System based on gender characteristics; 3) Gender only contributes 0.1% to the improvement of learning outcomes while 99.9% of other factors.

The aim of this research is to examine the influence of the Realistic Mathematics Education (RME) approach in improving students' mathematical communication ability. In this research, a quasi-experiment was used, with the research using the non-equivalent pretest-posttest control group design. Eighth grade students at PGRI 1 Cimahi Middle School were the subjects of the research. To measure mathematical communication ability, data was obtained from four test questions that had been tested previously. Next, the data obtained will be analyzed and processed using analysis of 2 dependent samples using a normality test first, followed by a paired t-test. Mathematical communication ability improve much better for students who use the RME Approach compared to students who use the regular learning approach.

Mathematical reasoning, mathematical communication, mathematical problem solving, conceptual understanding, mathematical understanding, creative thinking and critical thinking are part of the mathematical abilities that students must have. One of the goals of learning mathematics according to NCTM is learning to communicate (mathematical communication). Mathematical communication skills in mathematics learning really need to be developed. This type of research design uses a quasi-experimental research design, namely pretest and post-test with non-equivalent control group design . The research used research subjects into two groups, namely the experimental group and the control group. The subjects of this research were students of class VII I MTs As-Sa'adah Padahanten Majalengka, numbering 64 people. Subjects were selected based on experimental class VIII A, 32 people and control class VIIIB, 32 people. Walkthroughs, questionnaires, and tests are techniques used in data collection. Data processing analysis was carried out qualitatively and quantitatively. The results of this research are that there is a difference in the effectiveness of the Discovery Learning model learning approach with the ordinary (conventional) learning model in terms of the aspects of mathematical communication skills and self-esteem of MTs in statistics material. The implications of the Discovery Learning learning model in this research are that it makes it easy for students to remember the lessons learned, integrate self concept according to their initial abilities, focus, be creative in exploratory projects, and the effect of knowledge transfer on learning outcomes can last a long time.

Geometry has abstract notions to be learnt so that all those notions cannot be just transferred into students' mind like a bunch of information that should be memorized. Students need to construct those concepts during their learning process. This process of knowledge construction can be considered as an abstraction process. This study aimed to qualitatively compare abstraction process of students who learned the topic of triangle in conventional method and in van Hiele model of teaching aided by Geometers' sketchpad. Subjects of this study were junior high school students in grade 7. This is a qualitative study with grounded theory design. Data were collected through classroom observation, test, and task-based interview. Results of the study show that theoretical abstraction processes tend to dominate classrom with conventional method of teaching while classroom with van Hiele model of teaching aided by Geometers' sketchpad accommodated empirical abstraction process of the students.

This research aims to examine the improvement of mathematical communication skills of junior high school students in grade VII using the Problem Based Learning (PBL) model. The method used is quantitative with a quasi-experimental design involving two sample groups. One group is called the experimental class because it receives learning with the Problem Based Learning (PBL) model, the other is the control class whose learning uses the conventional model. The first meeting was given a pre-test and the last meeting was given a post-test. The population in this study was all grade VII of SMP PGRI Cibeureum. Then 2 classes were determined as samples, namely class VII-A as the experimental class and class VII-C as the control class. The data collection technique in this study used an instrument of students' mathematical communication skills which was given twice, namely during the Pre-test and Post-test. Data processing and analysis using Microsoft Excel application and SPSS software ver 25.0, the results of this research analysis show that the increase in mathematical communication skills of students of SMP PGRI Cibeureum whose learning uses the Problem Based Learning (PBL) Model is better than those who use conventional learning.

Problem-solving ability is an essential skill that must be possessed by students, especially in Vocational High Schools (SMK), in order to apply the concepts learned in real situations. However, many students have difficulty in identifying and solving mathematical problems because the learning method is still centered on the teacher and the minimal use of interactive learning media. This study aims to analyze the mathematical problem-solving ability of vocational high school students whose mathematics learning uses the Problem Based Learning model assisted by interactive media canva and quizizz compared to those who use regular learning. This study uses a quasi-experimental method with a Nonequivalent Control Group Design. The research sample consisted of 64 grade XI students of SMKN 1 Cariu, which were divided into an experimental class (32 students) who received learning using PBL assisted by interactive media Canva and Quizizz, and a control class (32 students) who used regular learning methods. Data collection was carried out through problem-solving ability tests (pretest and posttest), questionnaires and observations. Data analysis using inferential statistics, namely the average difference test with N-Gain as a measure of learning outcomes, and thematic analysis for qualitative data. The results of the study showed that the mathematical problem-solving ability of vocational high school students whose mathematics learning used the Problem Based Learning model assisted by interactive media canva and quizizz was better than those who used regular learning.
