几何概型是中学数学的一项重要的教学内容,由于是新增内容等原因,也是较难把握的教学内容.它的前置知识是概率的统计定义和等可能概念以及古典概型,是第二类等可能概率模型,它把等可能事件的概念从有限延伸到无限.等可能、无限是二个极其抽象的概念,为教学增加了难度.教学概率的目的是学习用数学方法去研究不确定现象的规律,培养学生用科学态度、辩证思维、随机观念去观察、分析、研究客观世界.学生主体,教师主导,即教学的双主性是被大
Geometry is an important teaching content in high school mathematics, because it is the new content and other reasons, but also difficult to grasp the teaching content of its pre-knowledge is the statistical definition of probability and other possible concepts and the classical profile is The second possible probabilistic model, which extends the concept of possible events from finite to infinite, etc. It is possible that infinite is a concept that is extremely abstract and adds to the difficulty of teaching.The purpose of instructional probabilities is to learn mathematical methods to study Uncertainty of the law, students with scientific attitude, dialectical thinking, random concepts to observe, analyze, study the objective world.Division of the student subject, the teacher, that is, the dual main is the teaching of large
