The purpose of this research is to improve the mathematical representation ability and learning independence through the Realistic Mathematics Education (RME) approach in students of class XI IPS 1 SMA N 1 Pekalongan. This type of research is a classroom action research study subjects were students of class XI IPS 1 SMA N 1 Pekalongan consisting of 25 students. This can be seen from the students' mathematical representation ability in linear program material by increasing data analysis (N-Gain) from the pre-survey to the first cycle obtained an average pre-test of 59.2 and an average post-test of 64.8 so that gain 0.30 with a percentage of 30% in the low category. Furthermore, the first cycle to the second cycle obtained an average pre-test of 64.8 and an average post-test of 77.4 so that a gain of 0.53 with a percentage of 53% in the medium category. Independence of student learning from pre-survey to the first cycle with a percentage of 54.6% increased to 65.05% with a high category. Furthermore, from cycle, I to cycle II with a percentage of 65.05% increased to 82.9% with a very high category.Keywords:Mathematical Representation, Self-regulated Learning, RME

AbstractThis study aims to determine the improvement of students' mathematical analysis skills, individual and classical learning completeness, and student learning interest in the tangent material of the VIII class MTs Usshuludin Singkawang by applying the Synectic learning model. This study uses a Quasi-Experimental design using the Nonequivalent Control Group form, the population in this study are all classes of VIII MTs Usshuludin Singkawang consisting of 5 classes totaling 149 people. The sample was taken using the Random Sampling Cluster technique, while the sample consisted of two classes, namely class VIII B (29 students) as an experimental class and class VIII D (30 students) as a control class. The data analysis technique used was the 1 sample t-test to calculate individual completeness, the proportion test to calculate classical completeness, the two independent sample t-tests to calculate differences in mathematical analysis ability improvement, and the one variable t / z test to calculate student interest in learning. The results showed: 1) There was mastery learning both individually and classically that got direct learning using synectic models, 2) There was a difference in the improvement of students 'mathematical analysis skills, the increase in the experimental class was higher than in the control class, 3) The students' interest in learning after being applied to learn using synectic learning models can reach more than 70% of the ideal value.Â Keywords: Synectic Learning Model, mathematical analysis ability, mastery learning, student interest in learning

The objectives of this study are to describe and create Student Worksheets based on Concept Mapping that are valid, effective, and practical to facilitate students' understanding of mathematical concepts. This research uses the Plomp research and development model that has been modified by Romadhan into 4 phases namely 1) initial investigation, 2) design, 3 ) realization, 4) tests, evaluations and revisions. The LKS was tested on a limited basis to three students of class VII A and field trials on 24 students of class VII D MTs Plus Darul Ulum. Data collection was performed using worksheet validation sheets, student response sheets, teacher response sheets, and concept understanding sheets. The results showed that the Student Worksheet (LKS) based on concept mapping to facilitate students' understanding of mathematical concepts had fulfilled valid, effective, and practical criteria. Based on the results of the validity percentage 80% and 78.13%. The results of the effectiveness based on student's responses in the questionnaire and result tests of conceptual understanding. Student worksheet effective is responses of students who meet both criteria with score Sf= 73,9% and test understanding of the concept which meets both criteria with score Sa= 80,29%. Practicability test on the student worksheet based on questionnaire responses of the teacher which meet both criteria whit score Sp= 76%. Proposition for further development, student worksheets should be developed in other topics of mathematics.Keywords: student worksheet, concept mapping, understanding of concept mathematical, algebra.

The purpose of this study was to examine the mathematical concepts of students in solving the problem of polyhedron of cubes and cuboids with assisted of Schoology media. This research uses qualitative methods with descriptive approach. This study describes the ability to understand mathematical concepts that owned of students with Schoology media. Research subjects is three students selected by purposive sampling based on conditions and situations that occured during the current co-19 pandemic. The data collection used consists of tests of understanding the ability of mathematical concepts. Based on the results of research showed that the ability to understanding students' of mathematical concepts with Schoology-assisted able to provide understanding of material polyhedron of cubes and cuboids by the average results of students getting value 91,67. Where the first student is able to reach an understanding indicator of mathematical concepts from given by agreeing to the concept, classifying objects according to certain properties, giving concepts in various forms of mathematical representation, explaining the relationship between one concept with another concept, and applying the concept in problem solving . While the second and third students can only reach four indicators from the second indicator given.
