基于FIAS的科学课堂言语互动行为分析及改进建议——以“一师一优课”平台上的“人类认识地球及其运动的历史”教学为例

Analysis of Verbal Interaction in Science Classroom Based on FIAS and Suggestions for Improvement:Taking the Teaching of“History of Human Understanding of the Earth and Its Movement”in“One Teacher,One Excellent Class”as an Example

课堂言语互动是教学的主要方式之一,可以直接反映教师的教学能力、学生的学习效率、课堂教学的效果。FIAS是利用定量化编码系统对课堂言语活动进行观察的工具。该研究选取了同上一节科学课的四位优秀教师的课堂教学实录视频,利用FIAS对其进行统计和分析,揭示了四位教师的教学特征,提出科学教师在教学过程中须调整课堂言语教学比率、优化教师言语表达的建议,从而取得更好的教学效果。

Classroom verbal interaction is one of the main methods of teaching,which can directly reflect teachers’teaching ability,students’learning efficiency,and classroom teaching effects.FIAS is a tool for observing classroom speech activities using a quantitative coding system.This research selects the classroom teaching videos of four outstanding teachers in the same science class,and uses FIAS to conduct statistics and analysis on these four classes.The results revealed the characteristics of these classes.Based on the observations of this study,we suggest that science teachers should adjust the classroom language teaching ratio in the teaching process and optimize teachers’language expression in order to achieve better teaching effects.
