Cognitive Development, Analytical Thinking, and Learning Satisfaction of Second Grade Students learned through Inquiry-based Learning

Science teaching needs to be able students having knowledge and understanding. Also, students have to develop their thinking skills it should help students meet real science through inquiry-based pedagogical process. This study aims to (i) investigate effective teaching criterion through inquiry-based teaching at 80/80, (ii) find out effectiveness index of inquiry-based teaching, (iii) compare analytical thinking between before and after students had learned by inquiry-based learning activities, and (iv) study learning satisfaction of second grade students after they had learned through inquiry method. Participants of the study were 10 second grade students, sampled by purposive sampling technique. Research instruments comprised of 8-lesson plan, 20-item achievement test, 20-item analytical thinking test, and 15-item questionnaire on learning satisfaction. Data were gathered and analyzed by Wilcoxon Matched Pairs Singed–Ranks Test. Results revealed that inquiry-based learning activities had effective criterion at 84.46/82.50; effectiveness index of inquiry-based learning activities was 0.5200; post test score of achievement test higher than those pre test score at .05 statistical significance level; and students had learning satisfaction on inquiry-based learning activities at highest level. It can be concluded that inquiry-based learning activities promoted students in terms of both cognitive, analytical thinking, and learning satisfaction. It should be suggested in for pedagogical preparation and incorporate it into science curriculum.
