Jinshan's TED Talk Playlist on Education

To educate independent thinkers, we need

  • Critical Thinking: keep asking why, never just accept/absorb knowledge.
  • Relational Thinking: try to connect concepts (explicitly, give the connections names) and also connect concepts to reality.
  • Meaningful Learning: what is it, why is it so and why is it organized/presented in this way, do I like it.
  • Big Pictures of disciplines under study : why do we want to learn this and that, what is the basic questions/typical ways of thinking of the discipline, to be able to think like/as experts in the disciplines.
  • Imagination and Creativity: to go beyond the limits, which, of course, one might needs to identify and be unsatisfied with first.

How to do it?

Our own work here at BNU: concept-mapping-/projector- based meaningful learning on learning how to learn and think

电梯池塘十字路口等图像识别和自动报警软件

有人在电梯里面困住，有人从桥上落下去，有人在路上出事故。现在，基本上是监控摄像全覆盖的。能不能做一个图像识别系统，把危险的事情都识别出来，并自动报警？

识别的方法可以基于规则，也可以基于大数据和算法（例如先收集一大堆危险的事情的视频，然后人工分类，接着训练）。

这样，妈妈再也不用担心我在小池塘玩耍了。

借贴：食堂菜品点评系统。给食堂的菜按照内容、位置和师傅编码，然后，可以让学生来点评。对于好评的菜给相应的师傅和食堂奖励。这个应该可以提高食堂的菜品的质量。

利用就餐卡数据实时显示每个食堂的现有人数，平均用餐时间，下一个时间段之内可以用餐完毕的人数。同理，用在澡堂等其他公共服务设施上。还可以进一步用来做科学管理，例如按照在校生数量（门卡）来决定开食堂澡堂等。

甚至可以给每一个教室（或者至少教学楼）安装上刷卡进入的设备，实时统计。用这个甚至可以考虑做学习时间的分配和管理的参考甚至研究。
