Improving Students’ Science Process Skills on Biology Using Bounded Inquiry Lab Model

Abstract

This research is to improve the students’ science process skills include four aspects: 1) formulating problem; 2)
formulating hypotheses; 3) constructing experimental design; 4) apply concept in Senses System,by applying bounded
inquiry lab model for second grade students at SMA Al Islam 1 Surakarta. This research is a classroom action research
(CAR), conducted in two cycles. Each cycle consists of planning, action, observation, and reflection. The research subject
was 35 students of science 3 at SMA Al Islam 1 Surakarta.Data collection techniques used: 1) non-test technique
(observation, interviews, and documentations); 2) test for science process skills. Data was analysed using descriptive
qualitative. The results show that there is an improvement of each aspect of science process skillsfrom Pre-Cycle to Cycle
2, i.e. formulating problem (39,46%; 50%;82,35%); formulating hypotheses (34,05%; 49,12%; 81,48%); experimental
design 34,05%; 49,12%; 81,48%); application concept (36,76%; 38%; 64,75%).Itcanbe concluded that the application of
bounded inquiry lab model can improve students’ science process skills.
