徐长青老师把学生放在主动探索知识规律的主体位置上,将数学知识和生活经验巧妙地结合在一起,营造出一个有趣的情境。进而按游戏的分类进入相应的呼啦圈,在学生玩呼啦圈的过程中,让学生更好地理解了重复的数学模型。
徐老师从学生易错易混问题出发,引导孩子们深度思考,在不断的观察、对比、表达、表演中,加深对概念的理解,提高具身认知,促进思维可视化。

徐长青老师把学生放在主动探索知识规律的主体位置上,将数学知识和生活经验巧妙地结合在一起,营造出一个有趣的情境。进而按游戏的分类进入相应的呼啦圈,在学生玩呼啦圈的过程中,让学生更好地理解了重复的数学模型。
徐老师从学生易错易混问题出发,引导孩子们深度思考,在不断的观察、对比、表达、表演中,加深对概念的理解,提高具身认知,促进思维可视化。
