基于教学切片的课堂观察:取样·制备·应用

Classroom Observation Based on Teaching Slices: Sampling, Preparation and Application

教学切片是教学实证研究的重要载体,教学切片取样一般源自教师的听课需求或与特定的听课目的有关。教学切片的制备应更多地指向学生的精神状态,一般采用预先规划好的固定拍摄,辅之以手机的适时捕捉。通过对教学切片的"数字化"处理,使教学诊断建立在对数字和现象的分析基础上。以定点教学切片为基本参照构建教学切片的系列参照,推动定点课改的常态化,进而促进教学效果的持续优化。

Teaching slice is an important carrier of teaching empirical research.Sampling of teaching slices usually comes from teachers’needs or is related to specific purposes of attending a lession.The preparation of teaching slices should be more directed to students’life state.Pre-planned fixed shooting is generally used,supported by the timely capture of mobile phones.Through the digitalization of teaching slices,teaching diagnosis is based on the analysis of numbers and phenomena.With fixed-point teaching slice as the basic reference,a series of reference of teaching slice is constructed to promote the normalization of fixedpoint curriculum reform,and then to promote the continuous optimization of teaching ecology.
