This study aims to determine the validity, practicality, and effectiveness of the audiovisual e-module for basic arithmetic operations based on understanding concepts and moral values. The development model used is 4D (Define, Design, Develop, and Disseminate). Data in the study were collected with validation sheets, practicality sheets, response questionnaires, and learning outcomes tests. After the define and design stages have been carried out, Draft I of the e-module is obtained. At the develop stage, a validity test was carried out on five validators, an empirical test was done to 1 teacher and 5 students, as well as a field test to a class 2A MI Humaira' Bengkulu City so that a valid, practical, and effective e-module was produced. This e-module has some advantages, namely providing interactive learning activities with clear and detailed pictures, videos and learning steps, motivating students to learn mathematics, explaining material according to mathematical concepts, containing moral values that can be imitated, giving project activities that can be done independently, as well as practicing students' mathematical problem solving skills.AbstrakPenelitian ini bertujuan untuk mengetahui kevalidan, kepraktisan, dan keefektifan e-module audiovisual operasi aritmatika dasar berbasis pemahaman konsep dan nilai-nilai akhlak. Model pengembangan yang digunakan adalah 4D (Define, Design, Develop, dan Disseminate). Data dalam penelitian dikumpul-kan dengan lembar validasi, lembar kepraktisan, angket respon, dan tes hasil belajar. Setelah dilakukan tahap define dan design dihasilkan Draf I Produk e-module.

Mathematical problem solving ability is surely the must-have any students in doinga math problem that is abstract. But many of the students who have not been able to use the problem-solving ability in doing a math problem. Many of them assumed that mathematics is a difficult lesson, and it usually requires a high concentration oflearning math. So the efficacy of self (self efficacy) is in need of students to cope with these problems. Self-efficacy (self efficacy) refers to the belief that relates to the ability and willingness of a student to achieve and complete tasks and results of the study with the target time has been determined and self efficacy refers to the consideration of how big someone's beliefs about their ability to perform a number of learning activities and their ability to complete tasks. Students who have a good self-efficacy will be successful in theirlearning activities andcanperform academic duties smoothly likewise viceversa if the efficacy in low students then have students will quickly give up on any problems in dealing with. Hence the need for self-efficacy so that arise from the student is either the later will provide confidence in the ability of students in solving mathematical problems.

Technology can be used to promote students' understanding of mathematical concepts and problem-solving techniques. Its use also permits students' mathematical explorations prior to their formal development in the mathematics curriculum and in ways that can capture students' curiosity, imagination, and interest. The NCTM's Curriculum and Evaluation Standards for School Mathematics (1989) recommends that “[i]n grades 9–12, the mathematics curriculum should include the refinement and extension of methods of mathematical problem solving so that all students can … apply the process of mathematical modeling to real-world problem situations” (p. 137). Students empowered with technology have the opportunity to model real-world phenomena and visualize relationships found in the model while gaining ownership in the learning process.

Abstract: Mathematics is a science that is universal and able to integrate with other subjects. One of the goals of mathematics learning based on Kurikulum Tingkat Satuan Pendidikan is to understand, explain and apply mathematical concepts in the context of problem solving. But in the field, the students tend to difficulties in resolving problems related to problem solving in mathematics. This is due to the low ability students in mathematical problem solving in students' learning because not used to thinking creatively. It required a real effort to improve students' problem-solving abilities in mathematics. One of the measures taken namely through mathematics model Multy Discourse Representation (DMR). Learning with models DMR is one alternative that can be used because it exposes students to work in groups, in order to issue a power of representation held by the students.Keyword: Problem solving ability, DMR Model, Mathematic learning. Abstrak: Matematika merupakan suatu ilmu yang sifatnya universal dan mampu berintegrasi dengan mata pelajaran lain. Salah satu tujuan pembelajaran matematika berdasarkan kurikulum tingkat satuan pendidikan adalah memahami, menjelaskan dan mengaplikasikan konsep matematika dalam konteks pemecahan masalah. Namun dalam pelaksanaan di lapangan, siswa cenderung kesulitan dalam menyelesaikan persoalan terkait pemecahan masalah dalam pembelajaran matematika. Hal ini disebabkan rendahnya kemampuan siswa dalam pemecahan masalah matematis karena dalam pembelajaran siswa tidak terbiasa berpikir secara kreatif. Untuk itu diperlukan upaya nyata dalam meningkatkan kemampuan pemecahan masalah siswa dalam pembelajaran matematika. Salah satu upaya yang diambil yakni melalui pembelajaran matematika dengan model Diskursus Multy Representation (DMR). Pembelajaran dengan model DMR merupakan salah satu alternatif yang dapat digunakan karena menghadapkan siswa kepada bekerja secara berkelompok, supaya dapat mengeluarkan daya representasi yang dimiliki oleh diri siswa.Kata kunci: Kemampuan pemecahan masalah, Model DMR, Pembelajaran matematika
