一节课几十张PPT:早就该被拉下“神坛”了
澎湃特约评论员 胡欣红
近日，全国政协委员、中国社会科学院文学研究所研究员刘宁一份关于PPT的提案，引发了舆论关注。
在她看来，这个小切口的提案反映了一个大问题——课堂教学过度使用PPT对基础教育和大学人文素质教育造成了很多负面影响。
互联网时代，PPT已成为教育教学的一个重要工具，很多老师习惯用它授课，学生也乐于接受这样图文并茂的教学形式，但这样的方式一定好吗？

PPT在提高课堂教学效率方面有着传统教学工具不可企及的优势，教师依靠粉笔与嘴巴解释不清的，课件能够清楚地表现出来。多媒体教学可以添加文字、动画、声音，使教学过程更加有趣，能够化抽象为直观，变难为易，使得学习方式更加多样化，有利于学生思维拓宽，有效调动学生学习积极性。
然而，PPT也是一把双刃剑。由于多媒体的强大功能，一度导致不少教师依赖甚至迷信课件。多媒体本应辅助教学，但反过来却主宰了课堂，令人啼笑皆非。事无巨细，一切都打在PPT上，一节课几十张PPT，学生应接不暇，课堂容量固然大大提高，但教学过程却被PPT所绑架，师生之间的从容交流荡然无存。

鉴于上述弊病，一度令人目不暇接的多媒体教学，经历了从“喧宾夺主”到回归辅助教学本位的变化过程。为了引导老师合理使用PPT，有学校甚至推出“限PPT令”：一二年级禁用PPT，其他年级限时使用PPT。实施之后，效果良好。没有了PPT的“牵绊”，老师能更好地走入到学生当中，师生双边教学活动配合更加默契，更加关注学生的成长，而不是让媒体、动画夹在老师和孩子中间，真正实现“以人为本、目中有人”。

换言之，在当前的实际教学中，多媒体手段并不是非用不可的，完全可以根据教学实际需求进行选择。即便使用课件，也要求“为我所用”，以板书和教学思路为主导，以PPT为框架，发挥其梳理知识结构和多样化解析知识点等优势。

PPT对教育教学的负面影响，早已不是什么秘密，师生对PPT的利弊也有了清晰的认识，既然如此，何以依然继续“喧宾夺主”呢？

PPT只是工具，取决于人怎么去使用，因此问题并不在PPT而在于人。当下，一些老师之所以还在过度使用PPT，主要基于两个方面的因素：一是在职称评定、教学比赛、公开课等场合，PPT依然是一个“加分项”。为了取得“效果”，PPT越做越复杂、越做越精美，这种形式主义风气让老师欲罢不能。

二则是部分老师备课过程偷懒，一个旧课件用个若干年，或者奉行“拿来主义”，从同行那里拷贝PPT。对于教学内容缺乏自己的理解和内化，如此行径，从某种程度上讲，就是一种教育不作为。

抨击PPT对教育教学的负面影响，是为了不让喧宾夺主的PPT拉教学的后腿，并不是一律限用乃至禁用。要不要用PPT，该怎么用PPT，关键在于把准其辅佐教学的定位，切莫陷入另一种极端。
诚如专家所言，PPT是工具，粉笔板书也是工具，课堂以人为本还是目中无人，从来不取决于工具，而是由讲课者的理念和价值取向决定的。否则，即便留下一黑板的“粉笔板书”又有何用？
