Draw-a-Scientist Test
The Draw-A-Scientist Test (DAST) is an open-ended projective test designed to investigate children's perceptions of the scientist. Originally developed by David Wade Chambers in 1983, the main purpose was to learn at what age the well known stereotypic image of the scientist first appeared. Following the simple prompt, "Draw a scientist", 4807 primary school children in three countries completed drawings. The drawings were then analyzed for seven standard indicators: lab coat, eyeglasses, facial hair, symbols of research, symbols of knowledge, products of science (technology) and relevant captions. From these indicators, Chambers was able to show that children began to develop stereotypical views of scientists from a very early age, with a progressively larger number of indicators appearing as the grades progress.
==History==
Chambers’ original 1983 DAST, based on surveys conducted between 1966 and 1977,〔 differs significantly, in both purpose and methodology, from the earlier Draw-A-Person and Draw-A-Man projective tests (such as Florence Goodenough in 1926; Harris,1963; Goodenow, 1977 ), which have been used as a measure of intellectual maturation, to elicit personality type and unconscious material, and as part of neuropsychologic tests for stroke victims. Chambers, rather, was responding to important essays by Margaret Mead and Rhoda Metraux, which identified typical stereotypical images of scientists in high school students, and D. C. Beardslee and D. D. O'Dowd, which was a careful examination of the college student image of the scientist.
Over the next 3 decades, several hundred researchers, mainly in the discipline of education, have used the Chambers DAST to gauge various social, cultural and educational factors in student perception of science and the scientist. Some of these variables are discussed below.
Kevin D. Finson published an extensive review of the DAST literature.
