Abstract

Penelitian ini bertujuan untuk meningkatkan keaktifan dan hasil belajar kimia siswakelas X3 SMA Negeri 1 Tanjung Raja melalui metode Buzz Groups. Metode yang digunakandalam penelitian ini adalah Penelitian Tindakan Kelas (PTK) yang dilakukan dengan tigasiklus. Tiap siklus terdiri dari empat tahap, yaitu : perencanaan, tindakan, pengamatan danrefleksi. Teknik pengumpulan data menggunakan lembar observasi dan tes akhir siklus. Rataratakeaktifan pada siklus I,II,III adalah 49,54%, 62,31% dan 72,54%. Rata-rata nilai hasilbelajar sebelum tindakan (To) adalah 62,27 (36,37%) sementara nilai hasil belajar pada siklusI,II,III adalah 79,64(72,73%), 82,12(81,81%) dan 87.58(93,94%). Hasil penelitian tersebutmenunjukkan bahwa penerapan metode Buzz Groups dapat meningkatkan keaktifan dan hasilbelajar siswa. Berdasarkan kesimpulan penelitian disarankan kepada guru kimia dan guru matapelajaran yang lain di sekolah dapat mengimlementasikan metode Buzz Groups sebagai sebuahalternatif untuk meningkatkan keaktifan dan hasil belajar, khususnya pada mata pelajaran kimia.

Abstract

This study aims to explore the views of pre-service chemistry teachers on the nature of science and technology. Pre-service chemistry teachers’ view of nature of science and technology (VNOST) is very important to help their students later in understanding the concepts of science. This research is the initial stage in didactical design research involving 48 pre-service chemistry teachers from Sriwijaya University. The descriptive method is used to explain the results of the analysis of pre-service chemistry teachers’ VNOST. Student views were assessed using the VNOST questionnaire, consisting of 8 questions and guided by the discourse of ionic liquid technology. Data collection uses a survey containing the views of pre-service chemistry teachers on VNOST and where each statement grouped according to three categories, namely "Realistic" (R), "Has Merit" (HM), and Naïve (N). The results showed that in general, students have the view of Has Merit (HM), or the belief that they chose is not entirely correct even though there are parts of statements that are still by the general view of science. The results of this student VNOST exploration are the basis for developing learning designs that are oriented to the realist answers of each question so that learning designs are produced based on aspects of the Nature of Science and Technology.
