Resumen: Se muestra un análisis descriptivo del contenido científico de las preguntas formuladas por estudiantes de secundaria y universitarios, cuando tratan de comprender el funcionamiento de dispositivos experimentales. Se consideran tres situaciones didácticas habituales: leer un texto acompañado de imágenes estáticas (esquemáticas); visualizar imágenes dinámicas (video o demostración de cátedra), observar y manipular los dispositivos. Solo una tercera parte de las preguntas de los estudiantes contuvieron algún término científico, aunque los universitarios superaron claramente a los de secundaria. Las leyes y principios científicos, necesarios para modelizar y explicar la realidad, apenas fueron mencionadas por porcentajes muy pequeños de estudiantes, incluso universitarios. Así mismo, se encontraron errores conceptuales e ideas animistas preocupantes. La condición observar y manipular, típica de laboratorios escolares y de museos interactivos, estimuló mayor proporción de preguntas y mayor variedad en el uso de términos científicos en los estudiantes.Palabras clave: Enseñanza de las ciencias, formulación de preguntas, dispositivos experimentales, uso de conceptos científicos.Abstract: A descriptive analysis on the scientific content in student's questions on experimental devices is developed. Secondary and university students were faced with experimental devices and tried to understand them. Three different but usual teaching conditions were considered: reading a text with still images, watching dynamic images as in video or teacher demonstrations, and watching and handling the devices. Only the third part of the asked questions mentioned at least one scientific term, although university students over performed secondary students. Scientific laws and principles were scarcely mentioned, although they are necessary to build a scientific model from reality. Some worrying ideas containing conceptual errors and animistic ideas were also found, even among university students. Handling the devices, as usual in laboratory setting and interactive museums, stimulated more questions and a higher variety of scientific terms used in students' questions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
