[size=5]133期小学组最优作品[/size]

陈宇老师
[url=https://www.netpad.net.cn/presentationEditor/presentationPlay.html#posts/4381]https://www.netpad.net.cn/presentationEditor/presentationPlay.html#posts/4381[/url]

突出优点：
课题引入，采用“设计引水线路”进行探索性实验，符合学生认知经验。先简单目测观察加以初步判断，再利用直尺工具测量，符合小学生学习方法特点。

建议：在学习平行线间的垂线段相等时，也采用先合理想象、猜猜，然后测量验证的方法，并且适当设计一些应用实例。

[size=5]133期初中组最优作品[/size]

郭根秋老师
[url=https://www.netpad.net.cn/presentationEditor/presentationPlay.html#posts/4386]https://www.netpad.net.cn/presentationEditor/presentationPlay.html#posts/4386[/url]

突出优点：
引入简洁，过程自然顺畅。从已知不共线三点确定一个圆入手提出问题：什么条件下不共线的四点能在一个圆上？随后根据已知同弧上的圆周角相等反过来，探究它的逆命题，得出猜想：同侧圆周角相等或异侧圆周角互补，则四点共圆，然后证明，再拓展变换，得出外角等于内对角的四边形是圆内接四边形。

付小华老师
[url=https://www.netpad.net.cn/presentationEditor/presentationPlay.html#posts/4374]https://www.netpad.net.cn/presentationEditor/presentationPlay.html#posts/4374[/url]

突出优点：
课件对丹德林双球模型构造，证明截口是椭圆都进行了全面设计。对于截口曲线为椭圆进行论证，采用了多种证明方法，备选充分。同时拓展到了截口为抛物线、双曲线的一般认识和证明上来，对本问题的探究与思考、拓展与推广研究深入。本课件还将圆锥变成圆台、圆柱，相应的截口仍是椭圆，证明方法思路一致，使得本课内容充分拓展而且体系化。同时还对离心率的计算方法也进行了研究。
