Pengembangan Media Pazzel Berbasis Discovery Learning Tentang Luas Permukaan Bangun Ruang di Sekolah Dasar

DEVELOPMENT OF PUZZEL MEDIA BASED ON DISCOVERY LEARNING ABOUT BUILDING SURFACE AREA  IN ELEMTARY SCHOOL

Geometri menawarkan cara dalam menginterpretasi dan menjelaskan lingkungan siswa serta dapat menjadi wadah bagi siswa untuk meningkatkan kemampuan berpikir kritis siswa untuk itu proses pembelajaran geometri harus memadai agar dapat mencapai tujuan tersebut. Namun nyatanya tidak sedikit proses pembelajaran geometri hanya berupa penyampaian rumus dan cara menggunakanya saja. Proses pembelajaran serupa juga dialami di SDN Jagir 2 pada materi luas permukaan bangun ruang sehingga diperlukan media pembelajaran untuk membantu siswa dalam memahami konsep luas permukaan bangun ruang. Penelitian ini bertujuan untuk: (1) Mengembangkan media pembelajaran yang dapat mengasah kemampuan berpikir kritis dalam bentuk pazzel berbasis discovery learning tentang luas bangun ruang, (2) Mengetahui kelayakan media pazzel berbasis discovery learning tentang luas bangun ruang di Sekolah Dasar. Penelitian ini menggunakan model pengembangan ADDIE yang terdiri dari 5 tahapan meliputi; Analyze, Design, Development, Implementation, Evaluation. Subjek penelitian ini adalah siswa kelas VI SDN JAGIR 2. Data dikumpulkan dengan observasi serta pengisian kuisioner. Data kelayakan media dianalisis dengan acuan konvensi dari ahli media dan ahli materi. Hasil peneitian ini adalah sebagai berikut: 1) komponen media pazzel berbasis discovery  learning terdiri dari kemasan, empat rangka bangun ruang (kubus, balok, prisma dan limas), pazzel dan buku panduan. 2) kelayakan media pazzel berbasis discovery learning Nampak berdasarkan hasil validasi oleh ahli materi yang mendapatkan rerata skor 3,85 yang artinya sangat valid dan juga hasil validasi oleh ahli media yang mendapatkan rerata skor 3,88 yang artinya sangat valid. Selain itu media pazzel juga diuji cobakan kepada 20 siswa kelas VI SDN Jagir 2 dan wali kelas VI dengan skor 3,56 yang berarti sangat layak. Hal ini berarti media pazzel berbasis discovery learning yang dikembangkan sesuai untuk diaplikasikan dalam proses pembelajaran matematika materi luas permukaan bangun ruang.

Geometry offers a way of interpreting and explaining the student's environment and can be a forum for students to improve their critical thinking skills. Therefore, the geometry learning process must be adequate in order to achieve these goals. But in fact, not a few geometry learning processes are only in the form of conveying formulas and how to use them. A similar learning process is also experienced at SDN Jagir 2 on the material of surface area of ​​the building so that learning media is needed to help students understand the concept of surface area of ​​the building.This study aims to: (1) develop learning media that can hone critical thinking skills in the form of puzzle-based discovery learning about the area of ​​​​building space, (2) determine the feasibility of puzzle media based on discovery learning about the area of ​​​​building space in elementary schools. This study uses the ADDIE development model which consists of 5 stages including; Analyze, Design, Development, Implementation, Evaluation. The subjects of this study were students of class VI SDN JAGIR 2. Data were collected by observation and filling out questionnaires. Media feasibility data were analyzed with reference to conventions from media experts and material experts. The results of this research are as follows: 1) discovery learning-based puzzle media components consist of packaging, four spatial frames (cubes, blocks, prisms, and pyramids), puzzles, and guidebooks. 2) the feasibility of discovery learning-based puzzle media appears based on the results of validation by material experts who get an average score of 3.85 which means it is very feasible and also the results of validation by media experts who get an average score of 3.88 which means it is very valid. In addition, the puzzled media was also tested on 20 grade VI students of SDN Jagir 2 and the homeroom teacher for grade VI with a score of 3.56 which means it is very valid. This means that the discovery learning-based puzzle media that was developed is suitable to be applied in the mathematics learning process on the surface area of ​​the surface area.
