Research-Oriented Collaborative Inquiry Learning (REORCILEA) Model: Improvement of Students’ Analytical Thinking Ability in High School Chemistry Learning

Abstract

This study aimed to determine the effect of applying the Research-Oriented Collaborative Inquiry Learning (REORCILEA) learning model on students' analytical thinking skills on the concept of acid-base. Participants in this study were 64 high school students divided into two groups: the control class and the experimental class. The sampling technique used was the random sampling technique. Data on students' analytical thinking skills were collected using post-test questions in descriptions containing indicators of analytical thinking skills with validity and reliability of the items are in good category. Analytical thinking ability data were analyzed using independent t-test. The results showed a significant effect of implementing the REORCILEA learning model on students' analytical thinking skills. Students' analytical thinking ability profile is known to have the highest percentage with a very high category, and the connecting aspect has the lowest percentage with the high category.
