模型式教学——从一道计数模型谈教学

Model Teaching from Teaching from a Counting Model

排列与组合不仅是组合数学的最初步知识和学习概率统计的基础,而且也是日常生活中应用比较广泛的数学知识。在组合数学的教学过程中,我们采用数学模型教学来教授学生,使学生能更好地掌握组合数学的相关知识,激发学生的求知欲,使学生进入问题情境,从而产生好奇心,形成探究愿望。从一道简单的计数模型出发,研究了组合数学的模型式教学。

The arrangement and combination are not only the most preliminary knowledge of combination mathematics and the base of learning probability statistics, but also used widely in daily life. In the process of teaching combination mathematics, we use mathematical models to teach to let students can better grasp the knowledge of combination mathematicsl, stimulate their desire for knowledge, enable them to enter the problem situation, create their curiosity and form the desire of exploration. In this paper, the model teaching of combinatorial mathematics is researched beginning from a simple counting model.
