Relevant CAT: Conceptual Diagnostic Test
Discipline: Chemistry
Description:
The Chemical Concepts Inventory (CCI) can be used to identify chemistry misconceptions held by students. The inventory is a multiple-choice instrument composed of non-mathematical conceptual questions (22 questions total). The questions are based on commonly-observed student misconceptions about topics generally covered in the first semester of a college chemistry course. A question from the inventory appears in the figure below. Development and validity data is available on-line in Mulford (1996).

Example Question from the CCI
|
Which of the following must be the same before and after a chemical reaction?
- The sum of the masses of all substances involved.
- The number of molecules of all substances involved.
- The number of atoms of each type involved.
- Both (a) and (c) must be the same.
- Each of the answers (a), (b), and (c) must be the same
