①We tend to think that friends and family members are our biggest sources of connection, laughter, and warmth. ②While that may well be true, researchers have also recently found that interacting with strangers actually brings a boost in mood and feelings of belonging that we didn't expect.
①In one series of studies, researchers instructed Chicago-area commuters using public transportation to strike up a conversation with someone near them. ②On average, participants who followed this instruction felt better than those who had been told to stand or sit in silence. ③The researchers also argued that when we shy away from casual interactions with strangers, it is often due to a misplaced anxiety that they might not want to talk to us. ④Much of the time, however, this belief is false. ⑤As it turns out, many people are actually perfectly willing to talk—and may even be flattered to receive your attention.
【分析题】
案例：
某教师通过摩擦起电、验电器等试验，使学生对电现象有了一定的感性认识。
教师：同学们.生活中有很多与电有关的现象。比如说，灯泡发光、静电现象等等。有谁知道电现象的本质是什么？
学生茫然一片，无人应答。
教师：其实在各种复杂的与电有关的现象背后，都有着共同的本质。今天我们学习最基本的电磁规律——库仑定律。
教师：库仑在18世纪，通过大量的实验总结出了这一规律。同学们，告诉老师库仑定律的形式是什么?
大部分学生纷纷说出了正确答案。
一学生喊道：“老师，我懂了，库仑定律和万有引力定律非常类似。”
教师对学生的观点提出了批评，说道：“你才预习了一节，就简单下结论”。
紧接着教师写出了库仑定律的形式，讲解了电荷的概念并布置了几道练习题。
问题：
(1)对老师的教学行为进行评析。
(2)基于该实验，设计一个包含师生交流的教学方案。
(3)设计一个教学片段，使学生对点电荷、库仑定律有深入的认识。
