Analysis of Undergraduate Students' Conceptual Consistency on Chemical Kinetics Using Four-Tier Chemistry Concept Inventory

摘要

The following research is aimed to investigate undergraduate students' conceptual understanding and their conceptual consistency in chemical kinetics. Moreover, it is also projected to classify the concepts based on easiness to be understood correctly or other that led to producing alternative concepts. This investigation had been carried out with 64 undergraduate students of the fifth semester of the Chemistry Education Department, Lambung Mangkurat University, who had finished the Reaction Rate topic. The instrument used was the Four-Tier Diagnostic Test and Chemistry Concept Inventory. Students' answers are classified based on their conceptual understanding. Besides, the answer's pattern showed the conceptual consistency that refers to their understanding. The whole students' conceptual consistencies were the basis that formed the conceptual model. The result shows that more students have alternative concepts than those who have misconceptions. Thus, only a few students have mastered the correct conceptions.
