“Development of LKPD Based on Realistic Mathematics Approach in Class IV Line Material at SDN 28 Padang Sarai”.

Abstrak

Mathematics learning in schools has the aim that students are able to: (1) understand mathematical concepts, explain the interrelationships between concepts and apply concepts or algorithms, flexibly, accurately, efficiently, and precisely in problem solving, (2) use reasoning on patterns and characteristics, perform mathematical manipulation in making generalizations, compiling evidence, or explaining mathematical ideas and statements, (3) solving problems that include the ability to understand problems, design mathematical models, complete models, and interpret solutions obtained, (4) communicate ideas with symbols, tables, diagrams , or other media to clarify the situation or problem, (5) have an attitude of appreciating the usefulness of mathematics in life, namely having curiosity, attention, and interest in learning mathematics, as well as a tenacious and confident attitude in problem solving. One of the learning approaches that can be applied by teachers is the Realistic Mathematics Approach. According to Fitrah (2016: 92) Realistic Mathematics Approach is one approach to learning mathematics that is oriented towards students, that mathematics is a human activity and mathematics must be connected in a real way to the context of students' daily lives to a learning experience that is oriented towards real things. (real). Based on the description above, there is no LKPD in schools and approaches that can be applied in schools, one of which is the Realistic Mathematics Approach which is related to the real world of students. Researchers will provide a solution in the form of LKPD based on the Realistic Mathematics Approach, which aims to make students able to solve mathematical problems related to real activities carried out in students' daily activities. This type of research is research and development (R&D). The development procedure uses 3-D, namely define, design and develop. The subject of the trial. The subject of the study was the fourth grade students of SDN 28 Padang Sarai totaling 28 students and the students studied were 14 people on line material. The instrument in this study used a validity and practicality sheet. At the validation stage, the media that has been designed is continued with validation activities by a validator consisting of 3 expert lecturers, namely material experts, design experts and language experts. And the practicality stage is carried out after the media is validated and feasible to be tested with the aim of knowing the level of practicality of the learning media. Based on the results of research on LKPD Development Based on Realistic Mathematics Approach (PMR) with an overall average validity of 81.15% valid category. Meanwhile, the results of the practicality of teachers and students are stated to be very practical with an average of 90.88%. From the results of the study, it can be concluded that the LKPD using the Realistic Mathematics approach (PMR) on line material for grade IV SD is very valid and practical to use in the learning process in grade IV SD.
