ABSTRACT
This study reports on the development and validation of test assessments designed to measure students’ creative thinking skills in a Visible Spectrophotometer (VS) and Atomic Absorption Spectrophotometer (AAS) apparatus modification project. The test form was an essay that was arranged based on Torrance’s Framework of creative thinking skill indicators. A preliminary draft of the test instrument was validated by three experts in the field of chemical education. The instrument was administered to third-year undergraduate students in the chemistry education study program in Province Lampung. The results showed that the internal consistency of the instrument was fairly good, which indicates that the instrument can be used to measure the acquisition of students’ creative thinking skills. This result is highly recommended for future empirical research in developing a creative thinking assessment, especially on the topic of a particular subject matter.
