SINGLE-TIER CHEMICAL CONCEPT INVENTORY (STCCI) TO IDENTIFY THE MISCONCEPTIONS OF TWELFTH-GRADE STUDENTS

Abstract

The study aimed to develop a Single-Tier Chemical Concept Inventory (STCCI) to identify the misconceptions in hydrogen bond among twelfth-grade students of East Bardhaman district, West Bengal, India. Initially, an inventory consisting of fifteen multiple-choice questions (MCQs) on the topic of hydrogen bond was developed. The validation process followed pilot testing with twenty-eight randomly selected students. Based on the CVR (Content Validity Ratio) values ten items were declared valid. After analysing ten items, the Cronbach’s alpha value was found to be 0.832, while the average item difficulty and the discrimination values were 0.5184 and 0.7625, respectively. Then, the standardized inventory was implemented to seventy-two twelfth-grade students having chemistry as a major for determining their misconceptions with the help of item distractors. Independent sample t-test was applied using Jamovi software to compare students’ misconceptions based on gender and locale. The results revealed that female-rural students showed the highest level of misconceptions.
