题目:Using “What if..” questions to teach science
Abstract
With the widening knowledge base students will need to be more flexible in their learning habits. Traditionally, teaching school science often involves teacher-centred methods like lectures, experimental demonstration or guided inquiry. Plain knowledge dissemination will not adequately prepare students to cope with the changing world. Hence, schools need to train students to be reflective in their learning habits – that is, getting students to be observant, to generate relevant alternatives and to make sense of these ideas. This article discusses a well-documented reflective learning strategy - the use of “what if” questions, to help students extend their learning beyond curricular requirements. Students are introduced to a distillation set up and then asked to pose “what if” questions about it. Their questions and the corresponding peer responses are a wealth of information for teachers to explore how science may be taught differently and with a greater impact on their students’ learning experience.
Introduction
The present science curriculum includes a range of student learning outcomes covering laboratory and experimental science (MOE, 2007). Researchers and scholars had argued that the roles of experiments and practical work in schools should allow students to practice laboratory skills, learn the various investigative processes and acquire first hand experiences in dealing with materials and laboratory wares (Boud, Dunn and Hegarty-Hazel, 1986; Doran et al, 2002; Hegarty-Hazel, 1986; Josephsen, 2003; Woolnough, 1990).Besides these cognitive and psychomotor objectives of school laboratory courses, there are also suggestions that lessons should be made more attractive through more intellectually demanding courses and new teaching techniques that can motivate students to learn (Schmidt, 2000).This paper discusses a well-documented reflective learning strategy - the use of questions posed by students to h
