Upaya Peningkatan Aktivitas Belajar Kimia Siswa dengan Penerapan Model Discovery Learning Melalui Program PDS di SMA Pembangunan Laboratorium UNP

Abstract

The low activity of students in learning chemistry at Senior High School of Pembangunan UNP needs to be overcome; one way is through the assignment of lecturers to schools. This study aims to increase student activity in chemistry learning at Senior High School of Pembangunan UNP. This classroom action research consists of three cycles which was done in eight meetings. The learning process used discovery learning and guided discovery learning models. Sample of this study consisted of 31 students at class XI MIPA which was selected randomly. The research instrument was observation sheet of student activities and the data were analyzed by percentage technique. Student activities which was observed consist of 12 items, namely (1) formulating problems, (2) formulating hypotheses, (3) collecting data, (4) answering the questions, (5) giving opinions/asking questions, (6) giving respond, (7) cooperating in groups, (8) help friends who have difficulties in learning, (9) proving the truth of the hypothesis, (10) writing conclusions, (11) ) presenting conclusions, and (12) doing homework. In the first, second, and third cycles, the average percentage of student activity was 58.5% in the medium category; 73.3% in the high category; and 81.7% in the very high category. Research findings indicate that the learning process used guided discovery learning models through the PDS program could increase student activity in chemistry learning at Senior High School of Pembangunan UNP. Therefore, the PDS program needs to be continued to improve the learning activities of high school students.
