几何概率模型教学中,经常遇到这样的情况——同一个问题用不同方法求解得到的概率结果不同,一题多果,模棱两可,一题多法,莫衷一是,给中学师生的教与学造成诸多困惑.问题的结症到底在哪里?为什么需要解释?令人困惑的问题层出不穷,不断涌现,研究清楚困惑的根源尤为重要!本人经过对现行教材、历史遗留问题和多篇有关文章的长期关注和研究,终于发现问题的关键所在,写出此
Geometry probabilistic model teaching, often encounter such a situation - the same problem with different methods to solve the probability of different results, a problem with many fruit, ambiguous, a multi-question method, impotence, to the teaching and learning of middle school students caused by Why do we need to explain? Confusing problems emerge in an endless stream and it is particularly important to study clearly the root causes of confusion! After long-term concerns about the existing textbooks, historical issues and many related articles And research, and finally found the crux of the problem, write this
