一、知识背景在课堂教学中,尤其是在数学实验的教学中,教师要引导学生自主探究,让学生经历从多角度认识问题、多种形式表达问题、多种策略思考问题的活动,发展其创新意识和应用意识,提高解决问题的能力,感受数学创造的乐趣,增进学好数学的信心,获得对数学较为全面的体验与理解。在此理念指导下,实验教学一定要倡导学生自主学 First, the knowledge background In classroom teaching, especially in the teaching of mathematical experiments, teachers should guide students to explore their own, so that students experience from multiple perspectives, multiple forms of expression, a variety of strategic thinking activities, the development of its Innovation and application of awareness, improve the ability to solve problems, feel the fun of creating mathematics to improve the confidence of learning mathematics, mathematics to obtain a more comprehensive experience and understanding. Under the guidance of this concept, experimental teaching must advocate student autonomy
