The interplay of representations and patterns of classroom discourse in science teaching sequences

The purpose of this study is to examines the relationship between the communicative approach of classroom talk and the modes of representations used by science teachers. Based on video data from two physics classrooms in Singapore, a recurring pattern in the relationship was observed as the teaching sequence of a lesson unfolded. It was found that as the mode of representation shifted from enactive (action based) to iconic (image based) to symbolic (language based), there was a concurrent and coordinated shift in the classroom communicative approach from interactive–dialogic to interactive–authoritative to non-interactive–authoritative. Specifically, the shift from enactive to iconic to symbolic representations occurred mainly within the interactive–dialogic approach while the shift towards the interactive–authoritative and non-interactive–authoritative approaches occurred when symbolic modes of representation were used. This concurrent and coordinated shift has implications on how we conceive the use of representations in conjunction with the co-occurring classroom discourse, both theoretically and pedagogically.     

拓宽欠发达地区筹资的视野

资金短缺是欠发达地区发展经济面临的主要瓶颈。为此，要突出重点，加强招商引资工作，努力打造招商引资的“洼地”，灵活运用各种招商引资的方法，动员区域内一切力量为招商引资服务，促进外商投资方式和投资领域多元化。要研究和掌握国际通行的BOT操作规程，充分了解各国贷款条件，鼓励使用国外租赁信贷，拓宽利用外资的渠道。还要增强当地资本的生成机制，提高当地资本的积累能力。
