“…Students' questions help to increase their motivation and interest in a topic (Chin & Kayalvizhi, 2005), foster discussion and debate in classroom discourse (Chin & Brown, 2002), and motivate knowledge construction (Chin & Brown, 2000). In science teaching, the questions that students generate can help to diagnose their understanding through formative assessment (Watts & Alsop, 1995;White & Gunstone, 1992), stimulate further inquiry into a topic via open investigations, problem-based learning, and project work (Chin & Chia, 2004;Crawford, Kelly, & Brown, 2000; Teixeira-Dias, Pedrosa de Jesus, Neri de Souza, & Watts, 2005), and provoke critical reflection on classroom practices (Watts, Gould, & Alsop, 1997).…”
