LANDASAN PENYUSUNAN PROGRAM PEMBELAJARAN MATEMATIKA BAGI SISWA TUNAGRAHITA RINGAN

Mentally retarded children or also called children with intellectual disability are children with below average intelligence who experience obstacles in adaptive behavior in the form of taking care of themselves and carrying out activities of daily living. Children with intellectual disability need special education and services to help them achieve optimal development. Children with mild intellectual disability require three basic skills, such as reading, speaking and arithmetic. The implementation of learning in the classroom, especially in learning mathematics requires learning modifications, so that they are in accordance with the individual conditions of intellectual disability students. Intellectual disability students have obstacles to think about something abstract, so in the preparation of learning programs the teacher is expected to; (1) understanding the characteristics of mild intellectual disability students, (2) conducting assessments, (3) being creative in modifying learning methods.

MEANINGFUL LEARNING DALAM PEMBELAJARAN MATEMATIKA

In the learning process not every student succeeds through the learning process done in other words not every student can achieve the learning objectives as expected. This is due to abstract mathematical concepts. Many factors influence it, including intelligence, learning readiness, interests, motivation, teacher abilities, maturity, family, school and community. The purpose of this study is to know the meaningful influence of learning on students' math learning outcomes. This research uses descriptive quantitative methods. The population in this study is all grade VII students of SMPN 1 Katibung Lampung Selatan. The results of the hypothesis test using the t-test showed the influence of meaningful learning application on improving the results of mathematics learning students of grade VII SMPN 1 Katibung south lampung. Students who apply meaningful learning have a higher average math learning outcome than the average student learning outcomes that do not apply meaningful learning. Thus, the application of meaningful learning can improve students' math learning outcomes.

Analisis Kesalahan Siswa Dalam Menyelesaikan Soal Pemecahan Masalah Matematika Berdasarkan Teori Newman

Problem solving ability is one of the mathematical abilities that need to be mastered by students to equip students in logical, analytical, systematic thinking and the ability to work well together. In addition, this problem solving ability is very important for students to train students in solving problems in everyday life. This study aims to analyze student errors in solving mathematical problem solving problems based on Newman's theory. The type of research used is descriptive qualitative. The subjects of this study were students of class VII-A SMP Muhammadiyah 1 Menggala. Data collection used in the form of tests, interviews and documentation. The results showed that the most mistakes made by students were in writing the final answer, which was caused because students did not understand the commands in the questions well. The second most common error is the transformation error caused because students do not have the skills to change the language of the problem into a mathematical model. The third error, namely misunderstanding the problem caused by students not being careful in writing down the information in the problem, and not getting used to writing down the information in the problem when solving math problems. The fourth error, namely the error of process skills caused by students not being careful in carrying out the calculation process

Desain Didaktis Materi Kaidah Pencacahan Untuk Siswa SMA Kelas XI

This study aims to develop didactic design on counting rules for senior high school. The didactic design is designed by considering two things the result of the test analysis of learning obstacle instrument and learning trajectory. This didactic design consists of four meetings obtained through the three formal stages performed in the study. The first stage is prospective ie didactic situation analysis before learning in the form of hypothetical didactic design including pedagogical didactic anticipation (ADP), second phase metaped analysis is notthe form of design implementation phase, and last stage is retrospective analysis which is an analysis that relate result of prospective analysis with metaped analysis nottik used to formulate empirik design. The research for preparing the didactic design begins with the provision of difficulties in learning the material of the counting rules and the analysis of the teaching materials. The results of the learning obstacle test show that students experience learning barriers that are categorized into three, namely ontogenic obstacle, didactical obstacle, and epistemological obstacle. The didactic design was implemented to 35 students of class XI in one of the senior high school in South Jakarta. Based on the results of research, didactic design developed this can be used as an alternative teaching materials concept of counting rules to minimize student learning barriers.
