Resumen

Resumen: Durante décadas, numerosas investigaciones han identificado la existencia de imágenes estereotipadas sobre los científicos mediante el empleo del método Draw-a-Scientist-Test (DAST). No obstante, las limitaciones metodológicas asociadas al DAST cuestionan los resultados obtenidos y resaltan la necesidad de desarrollar nuevos protocolos para evaluar las concepciones de los estudiantes acerca de los científicos. En este trabajo, tras revisar las deficiencias metodológicas del DAST, se proponen algunas modificaciones al protocolo original probadas en una prueba piloto con 149 estudiantes de 2º a 6º curso de Educación Primer de diversidad cultural. Los resultados iniciales muestran que las modificaciones realizadas ayudan a reducir algunos de los problemas metodológicos identificados en el uso del DAST, permitiendo identificar e interpretar de manera más fiable las concepciones de los estudiantes sobre los científicos.

A revision of the Draw-a-Scientist-Test (DAST)


Abstract: For decades, studies have shown the existence of a stereotypical image of scientist between children among the world using the Draw-a-Scientist-Test (DAST) method. However, the methodological limitations associated with the DAST question the results obtained and highlight the need to develop new protocols to evaluate students’ conceptions about scientists. In this paper the methodological deficiencies of the DAST instrument are reviewed and some changed made to the original protocol are described. The pilot test carried out with 149 students of cultural diversity enrolled in 2nd to 6th grades of Elementary School shows that this modification allows a more reliable identification and analysis of students’ conceptions, reducing some of the methodological problems identified in the use of DAST.


Keywords: image of scientist, Draw-a-Scientist-Test, science stereotypes, primary school, cultural diversity
