高中数学思维可视化课堂的建构——以“抛物线”教学为例

The Construction of High School Mathematical Thinking Visualization Class: Taking “Parabola” Teaching as an Example

以“抛物线”教学为例,建构高中数学思维可视化课堂,利用实物教具、信息手段、图示技术3种可视化策略,将隐性的思维路径直观地呈现出来,以实现“折”“绘”“图”3个教学环节的可视化,达到教学过程、教学方式、教学内容的全面可视化,减少学生的认知负荷,促进知识内化,推动深度学习,从而提升课堂教学效率.

Taking “parabola” teaching as an example, the visualization class of high school mathematics thinking is constructed, and three visualization strategies of physical teaching aids, information means and graphic technology are used to visually present the implicit thinking path, so as to realize the visualization of the three teaching links of “folding”, “drawing” and “picture”, and achieve the comprehensive visualization of the teaching process, teaching method and teaching content. Finally, the cognitive load of students can be reduced, promoting the internalization of knowledge and deep learning, so as to improve the efficiency of classroom teaching.
