文章根据“情境-模型”双向建构的角度,从了解内容板块,确立建构任务;掌握教学目标,择选建构素材;丰富呈现方式,确定建构过程;整合教学片断,完成建构设计;反复论证修改,完善教学设计等方面对小学数学教学设计的思路进行了探究。教师作为教学建构的组织者应注重调控与应变,作为建构的引导者应注重启发与思考,作为建构的合作者应注重平等参与等方面的问题。
According to the “context-model” two-way construction, the article from the understanding of the content of the plate, the establishment of construction tasks; master the teaching objectives, choose the construction material; rich presentation, to determine the construction process; integration of teaching fragments, to complete the construction design; Modify, improve the teaching design and other aspects of primary school mathematics teaching design ideas were explored. As the organizer of teaching construction, teachers should pay attention to regulation and response. As the guide of construction, teachers should pay attention to inspiration and thinking. As a partner of construction, teachers should pay equal attention to equal participation and so on.
