- Abstract
This study aims to produce a four-tier diagnostic test instrument on concepts in Chemical Kinetics where students experience misconceptions through the four-tier misconception diagnostic test. The test was developed based on several concepts: reaction rate, activated complex, reaction rate law, reaction order, rate constant (k), activation energy, catalyst, integral rate equation, half-life, reaction mechanism, overall reaction, elementary reaction, and Intermediate. This research developed a four-tier test diagnostic test instrument for concepts in Chemical Kinetics according to which consists of 6 stages (clearly identify the outcome, determine to measure the outcome achievement, determine the specific details, determine when to administer the instrument, design the instrument, and pilot test the revise the instruments). The instrument used to gain the validity data was a validation sheet given to the rater. The source of the data for this research is the expert appraiser from rater. There were 4 raters who gave a score for each question item in the four-tier diagnostic test. This development of the four-tier diagnostic test instrument was analyzed for theoretical validity in terms of content and construct (language and graphics) validity. The findings present theoretical valid for 19 questions of four-tier diagnostic test developed on kinetics concepts in content and construct a point of view.
