基于预学习数据分析的精准教学决策

Precision Instructional Decision-making based on Data Analysis from Pre-learning

作为一种高效的面向知识的教学方法，精准教学能够借助信息技术数据分析的优势，激发内在活力。在教育信息化深化发展的背景下，“普陀J课堂”平台将学生预学习阶段产生的数据记录并收集，通过对预学习数据的精准挖掘，对学生的预学习成效实施精准定位，辅助教师开展精准教学决策，以实现信息技术支持下的精准帮学。基于预学习的精准教学为微视频预学习后的课堂教学提供了一种可行的实践路径。

As an efficient method for knowledge teaching， Precision Instruction is able to activate its own power with the help of information technology. In the background of the extensive development of educational technology， many teachers in K-12 education adopt a teaching form of Micro-video plus Flipped Classroom. PUTUO J-Class Platform has been developed to record and collect data during student’s pre-learning process. It precisely digs into the data， pinpoints the level of students’ knowledge and recognition， and helps teachers choose the suitable precision decisions， with the purpose of technology enabled Precision Instruction and Learning.
