PENGARUH METODE INKUIRI TERBIMBING TERHADAP KETERAMPILAN PROSES SAINS DAN HASIL BELAJAR BIOLOGI SISWA KELAS VIII DI SMPN 3 GUNUNGSARI TAHUN AJARAN 2013/2014

: Students are capable to improve their skills in scientific process and to get meaningful learning both by inquiry learning and learning by doing. Many researches reported that learning by doing and inquiry learning could improve student's achievements, including cognitive achievement and secientific process skills. It was observed that Biology learning at school still mainly emphasize on conceptual, theoritical, recitation learning through textbook and tend to be teacher centered. The students were unfamiliar to do scientific inquiry through experiment and train their scientific process skills. As a consequence, their learning achievement still unsatisfied. Guided inquiry method is expected can overcome this problem. Therefore, the aim of this research is to examine the effect of guided inquiry method on student's scientific process skills and Biology learning achievement. This research was conducted in SMPN 3 Gunungsari from January to March 2014. Population of this study were all students at grade VIII of academic year 2013/2014 which divided into five classes, VIII A – VIII E. Samples were determined by simple random sampling technique and obtained VIII A as experimental class and VIII C as control class. Research design was nonequivalent control group design. Instrument to measure both student's scientific process skills and Biology learning achievement was a valid multiple choices test. Data of students's Biology learning achievement and scientific process skills were analyzed by using t-test formula at level of significant 5%. Results showed that students's Biology learning achievement and scientific process skills in both classes were not significantly different. Therefore, it can be concluded that effectiveness of expository and experiment method is as good as guided inquiry method on students's Biology learning achievement and scientific process skills.
