教学设计对数学教学知识发展的影响

Influence of Instructional Design on the Development of Mathematical Pedagogical Content Knowledge

教师基于自己的学科知识、经验等,借助于"课例学习+行动跟进+经验打磨+实践反思"等"行动学习"策略进行教学设计,实现有效教学,不断重组、提升学科教学知识。通过强化教学设计(实践),解决数学教学中存在的问题和困惑,在实践中传递、积累数学教学知识,在反思体验基础上改进课堂教学,发展数学教学能力,提升数学教师的数学教育观念。

The teacher implement teaching design, paying attention to the formation of knowledge and students＇ learning process and method based on subject knowledge, experience, his belief and with the help of the＂lesson study＋action＋experience＋reflection on the polished up＂and＂action learning＂strategy. Thus, teacher realizes the effective teaching and improves teaching knowledge（PCK）by constantly restructuring. The teacher through strengthening the instructional design （practice） solves the existing problems and confusion in the teaching of mathematics and transfers, accumulation of knowledge for teaching mathematics（MPCK）in practice. The teacher improves classroom teaching reflection, develops mathematical teaching ability （MPCA）and the concept of mathematical education promots mathematics teachers in the experience foundation.
