线上深度教学的局限性探讨

线上深度教学，是以教师深度的知识教学为基础，促进学生开展“激活—联结—评价—迁移”深度学习，以实现学生认知、情感和实践能力深度发展的一种活动。学科知识的深度教学是指知识的外在形式和知识的内在意蕴的教与学。由于目前网络学习平台发挥的功能不全，及教师对线上教学的规律认识不够，线上教学存在域限性、时限性、不可控性、单向性等几个方面的特征，从而带来了线上实现深度知识教学，促进学生深度学习，以及实现学生深度发展方面的局限性。克服这些局限性，要充分发挥网络平台在深度教学中的作用，认真做好线上深度教学设计，以及实现线上教学与线下教学的深度融合。

On the Limitations of Online Deep Teaching: From the Perspective of Deep Teaching of Subject Knowledge

Online deep teaching is an activity based on teachers'' deep knowledge teaching to promote students'' deep learning process of activation, connection, evaluation and transfer, so as to realize the deep development of students'' cognition, emotion and practical ability. Due to the incomplete functions of the current network learning platform and teachers'' insufficient understanding of the laws of online teaching, online teaching has the characteristics of domain limitation, time limitation, uncontrollability and unidirectionality. Thus, it brings about the limitation of realizing online deep knowledge teaching, the limitation of promoting students'' deep learning process, and the limitation of realizing students'' deep development. To overcome these limitations, we need to fully understand the limitations of online deep teaching, give full play to the role of network platform in deep teaching, make concrete efforts in online deep teaching design and realize the deep integration of online teaching and offline teaching.
