| 摘 要： | 以"几何概型"引入的两节同课异构的公开课为背景,从情境创设的对比和概念原型的利用两个环节剖析,提出教学设计的改进建议。同时结合"几何概型"引入三个设计要点,即需了解学生的初始能力;要试验探究的合理性;应规避难点集中的问题。

| Abstract: | Based on two open lessons with heterogeneous with “Geometric Models of Probability”as a lead-in, the essay puts forward suggestions from the analysis of two teaching procedures: comparison of teaching situation creation and use of concept prototype. On the three key points in teaching design with“Geometric Models of Probability”as a lead-in, it is further proposed that:understand the initial capabili-ty is important, experiment whether the exploration is reasonable or not is necessary, and difficulties in teaching should be avoided. |
