一、教学设计的理论依据建构主义学习理论认为学习是学习者与学习材料不断交互作用,获得知识主动建构的过程。学习者在学习时首先对学习材料进行识别,根据学习材料的属性进行相应方式的建构,如果学习材料与原有认知结构具有相同的类属,则采用同化的方式建构,以丰富原有的认知结 First, the theoretical basis of instructional design The constructivist learning theory believes that learning is the process of continuous interaction between learners and learning materials and the acquisition of knowledge. When learning, learners first identify the learning materials and construct the corresponding materials according to the attributes of the learning materials. If the learning materials have the same generics as the original cognitive structures, the learners use the assimilation method to enrich the original materials. Cognitive node
