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. Nevertheless, students show positive responses to Schoology media.Â Keywords: Understanding Mathematical Concepts, Schoology Media

This research is an exploration of the implementation of learning geometry mathematics through discourse and aims to get a model of theaching materials as adevelopment of those used by lecturers so far. The research was carried out through questionnaires, direct observation, and discussion of critical discourse analysis and was linked to important needs in mathematicals literacy. Exploration is constructed through theoretical reviews, synthesis from previous research, and examples of development though discourse. The contens of the questionnaire follow the natural discourse of the presentation of theacing materials on the dispotitions of lecturers and students. In particular, the exploration of theaching materials as part of the means of disseminating a culture of mathematics, an aesthetic description of mathematics, and dominant aspecs of lecturers and students. Development road maps are done through centralized examination of discourse, where data tajen from oral and written delivery and from texts that extend views on mathematics and by opening the choice of lectures and students. The result showed the depth of the description of teaching materials without the assumption that curriculum were sufficient to obtain the effectiveness of mathematical literacy and as a more contextual product.Keywords: theaching material, curriculum, continuity of the discourse of mathematics
