Secondary Education Students’ Questions on Experimental Devices

Abstract

Questions are essential in the construction of new knowledge by scientists. Nevertheless, students ask very few questions in usual classroom situations. In this paper we review the research work on question generation and describe three empirical studies conducted with students of different educational levels facing experimental devices. The aims were: 1) To stimulate and to analyse the questions asked by students when trying to understand the devices; 2) To probe the idea that most of the information seeking questions are originated by failed inferences; 3) To study the influence of the level of students’ knowledge on the questions asked. The procedure produced a significant quantity of information seeking questions, caused by the students’ awareness of misunderstanding. The results obtained support the taxonomy of questions proposed and show that higher knowledge students ask significantly more questions addressed to the scientific model construction than lower knowledge students. The results are replicated consistently.
