Enhancing Students' Cognitive Outcome in Chemistry by Guided Inquiry Learning Models

Ryzal Perdana, Ratu Beta Rudibyani


This study aims to determine the effectiveness of guided inquiry learning models on salt hydrolysis material to students' cognitive learning outcomes. Quasi experimental research uses pre-test and post-test control group design. The research was conducted in senior height school in East Lampung, Indonesia. The subjects of this study consisted of 36 students of XI IPA 1 as experimental class using guided inquiry learning model and 36 students of XI IPA 4 as control class using lecture method. The data were collected using the test technique in the form of 30 multiple choice questions. Data were analyzed by t-test using SPSS. The results showed that the t-test in the experimental class was obtained by probability (p) -6,347 (p <0.05), so H0 was rejected. The results showed that there was a significant difference between the pretest and posttest score of the students using guided inquiry model with N-gain of 0.900. The learning outcomes in the control class also increased but not as large as in the N-gain experimental class of 0.414. It can be concluded that guided inquiry learning model enhancing students' cognitive learning outcomes.
