Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui bentuk miskonsepsi dan penyebab miskonsepsi siswa kelas XII SMA Negeri 1 Sambas. Metode penelitian yang digunakan adalah deskriptif. Sampel penelitian sebanyak 27 orang siswa. Hasil penelitian menunjukkan terdapat 14 bentuk miskonsepsi siswa meliputi sub konsep pengertian reduksi dan oksidasi berdasarkan pelepasan dan pengikatan elektron, pengertian reduksi dan oksidasi berdasarkan perubahan bilangan oksidasi, penentuan bilangan oksidasi unsur, menentukan persamaan reaksi reduksi dan oksidasi berdasarkan pelepasan dan pengikatan oksigen, penentuan persamaan reaksi reduksi dan oksidasi berdasarkan pelepasan dan penangkapan elektron, penentuan persamaan reaksi reduksi dan oksidasi berdasarkan perubahan bilangan oksidasi, reduktor dan oksidator, serta tata nama dan rumus kimia senyawa yang melibatkan bilangan oksidasi. Penyebab miskonsepsi siswa adalah pemikiran asosiatif siswa, prakonsepsi yang salah, intuisi yang salah, dan kemampuan siswa.   Kata kunci : miskonsepsi siswa, penyebab miskonsepsi, reduksi oksidasi   Abstract: This research aims to determine types of misconception and cause of misconception in grade XII SMA Negeri 1 Sambas. The research method that used descriptive. The research sample which had been used was 27 students.

Abstract

This research aims to improve the quality of learning through laboratory infrastructure facilities at Sma Negeri 1 Polokarto. This research uses a qualitative approach with a type of descriptive approach. The subjects in this study are the heads of biology laboratories, chemical laboratories, physics laboratories, and computer laboratories. Methods of collecting data by means of observation, interview, and documentation. Infrastructure facilities data obtained then compared to the standards that have been determined based on Permendiknas No. 24 of 2007. The results showed that 1.) The laboratory is an important part of the learning process. 2.) Overall the laboratory at Sma Negeri 1 Polokarto has met permendiknas standard No. 24 of 2007. 3.) Chemical and computer laboratory facilities are complete or adequate. 4.) Lack of complete equipment in biology and physics laboratories. 5.) There are several procurement of facilities and infrastructure that are not carried out from the school to the government.
