Abstract
This study aims to develop creative research instruments for prospective chemistry teacher students in environmental chemistry courses. This instrument was developed using the 4D model, but was carried out until the expert validation test stage was carried out by 3 expert validators who were competent in the field. The results of the validation carried out by the three validators obtained an average score of 3.62 with very valid criteria. The instrument questions were made based on the TTCT-V (Torrance Test of Creative Thinking Verbal) on water pollution. Besides being able to see creative thinking abilities, this test can also show students' cognitive abilities and problem solving. However, it is necessary to carry out further research to see the practicality and effectiveness of the developed test instrument.
