Research-Oriented Collaborative Inquiry Learning Model to Improve Students’ Science Process Skills in Reaction Rate Topic

Abstract

This research aimed to improve students’ science process skills and to describe the profile of students’ science process skills in the Research-Oriented Collaborative Inquiry Learning (REORCILEA) in reaction rate learning. A quasi-experimental design had been employed in this research. The sample in this research was the 11th-grade students of a senior high school in Kroya, Indonesia. The experimental group and control group were chosen by using a random sampling technique. The observation sheet consisted of 15 indicators developed from 9 aspects of science process skills namely designing an experiment, identifying variables, formulating hypotheses, measuring, experimenting, observing, interpreting data, inferring, and communicating were used to obtain the data on students’ science process skills. Independent t-test analysis techniques and descriptive quantitative were used in this research. The result showed that the implementation of REORCILEA has a significant influence on the science process skills of high school students. Profile of students’ science process skills in REORCILEA in each indicator showed good and very good categories. REORCILEA model could be considered an effective strategy in improving students’ science process skills.
