"Development of Flat Building Material Paste Board Media Class IV SDN 27 Koto Baru Pantai Selatan

Abstrak

According to Dinni (2018), mathematics is a science related to abstract concepts, therefore the presentation of mathematical material in learning is often associated with daily life with the aim that students are able to find concepts and develop their mathematical abilities based on experience or knowledge that has been possessed by students. Therefore, to support the mathematics learning process, a learning medium is needed. In the learning process at school, teachers use the lecture method and only use theme books and LKS, without the addition of other teaching materials so that students have difficulty in understanding the learning material delivered by the teacher. The researcher conducted a development research entitled Development of Media Sticky Board Material For Building Flat Class IV SDN 27 Koto Baru Pantai Selatan. This type of research is research and development (R&D) with a 4D development stage, which is described as Define, design, development and dissemination which is modified into 3-D. This research is carried out until the development stage. The test subjects of the MediaBoard Paste Material For Building Flat Grade IV SDN 27 Koto Baru Pantai Selatan, which totaled 15 students. At the validation stage, the media that has been designed, continued with validation activities by validators consisting of 2 lecturers at the Faculty of Teacher Training and Education, Hatta University. For the practicality stage, it is carried out after the medial is validated and is feasible to be tested with the aim of knowing the level of practicality of the Learning media that has been made. Based on the results of research on the development of Flat Build Paste Board Media, an overall validity average of 84.13% was obtained, with valid criteria, while for the average practicality by teachers and students, an overall average of 98.31% was obtained with very practical criteria. From the results of the study, it can be concluded that the flat building sticky board media is valid and very practical so that it can be used as one of the teaching materials in mathematics learning, especially for grade IV students in elementary schools.
