几何概率是高中数学新课标教材中的新增内容,由于《普通高中新课程标准》教材的多样性,对几何概率模型知识的阐述有着这样或那样的细微差别,在为广大教师和学生提供丰富“素材”的同时,也使教师和学生在“几何概型”的教与学的过程中,遇到不少困惑与疑难问题,最典型的问题就是“贝特朗问题”对中学几何概率模型教学的困扰,值得探究,值得讨论,尽早达成共识,以利于更好的使用
Geometry Probability is a new content in high school mathematics teaching materials. Due to the diversity of teaching materials of “New High School Curriculum Standards”, there is one or more subtle differences in the explanation of the knowledge of geometric probability models. For the majority of teachers and students At the same time, teachers and students also encounter many puzzles and difficult questions in the process of teaching and learning of “geometric patterns.” The most typical problem is that “the Bertrand problem ”Disturbing Middle School Geometry Probability Model Teaching, It is worth exploring, it is worth discussing, as soon as possible to reach a consensus, in order to facilitate better use
