The Use of Fractional Manipulative Media to Increase The Conceptual Understanding of Elementary School Students

Learning mathematics at the elementary school level is very important in planting basic concepts about the concepts being taught. One effective way of learning mathematics in planting these concepts is by using manipulative media. Based on the results of observations of researchers in class II C of Muhammadiyah Elementary School, Nitikan, Yogyakarta obtained: 1) mathematics learning rarely uses the media, 2) the subject of fractions is difficult material with marked results of the pretest only 53.1% who reach minimum completeness criterion. This study aims to describe learning using manipulative media to improve understanding of the subject matter of fractions. This study uses a Classroom Action Research (CAR) design. The subjects of this study are class II C of Muhammadiyah Elementary School, Nitikan, amounting to 32 students. Data collection techniques used are observation and test. Data analysis in this classroom action research is quantitative and qualitative data analysis. The results showed the ability to understand the concept of mathematics in the first cycle is 62,5 % with good criteria and the second cycle is 78.1 %  with good criteria. The results of observations of the feasibility of using manipulative media in learning mathematics on the subject matter of fractions seen based on the activities of teachers and students during the learning process. Based on research that has been done, it can be concluded that the ability to understand mathematical concepts and student learning activities in class II C of SD Muhammadiyah Nitikan increases after the application of learning using manipulative media

LEARNING STRATEGIES FOR STUDENTS WITH DIFFICULTY LEARNING MATHEMATICS (DISCALCULIA) IN CLASS XI

This study aims to describe the learning strategies in learning approaches and learning methods and the impact of using these learning strategies for dyscalculia students in class XI of State Special Need School (SLBN) Tamanwinagun Kebumen in the 2018/2019 academic year. The subject of this study was a student of class XI Sate Special School (SLBN) Tamanwinagun Kebumen in the 2018/2019 academic year with the source of research data, namely a classroom teacher. This research's object is the mathematics learning strategy for students having difficulty learning mathematics (dyscalculia). Data collection techniques in the form of observation, interviews, tests, and documentation. The data analysis used an interactive model from Miles and Huberman, which describes conditions or phenomena as they are. The research conducted by researchers used a qualitative approach with a study design at SLBN Tamanwinangun Kebumen. The results showed that the teacher's learning strategies for dyscalculia consisted of learning approaches and methods. The learning approach includes a contextual approach, and an individual approach with an approach suitable for students is a contextual approach. The learning methods used include the lecture method, the question and answer method, the assignment method, and the visual method. The appropriate learning method for students is the visual method. The application of learning strategies in the form of approaches and methods used by the teacher in overcoming student dyscalculia impacts learning mathematics. This impact can be seen from the cognitive aspects of the students with dyscalculia, including memory, understanding, application, analysis, evaluation
