【事实(例题讲解)】
优点:通过对比实验,让同学们清晰的看到氧化铝在氢氧化钠溶液以及盐酸溶液中反应速率的不同,便于学生记忆;讲解过程条理清晰,语言流畅。
不足:在讲解氧化铝在氢氧化钠溶液以及盐酸溶液中反应速率时,对比试验中,在保证氧化铝的量相等的情况下,氢氧化钠和盐酸的物质的量浓度之比应该为3:1,而不是实验中的2:3;同时在讲解两个反应的反应方程式的时候太过简略了。
【操作演示讲解】
优点:在观看实验视频时,强调了实验中应注意的地方,更好的引导了学生观察及思考;在演示实验时,注意提醒学生操作上要注意的地方。
不足:在实验之后可以让学生复述他们所看到的现象会更好
【组织管理】
优点:课堂组织有序紧凑,时间合理;语言生动,学生投入度高;课堂无突发事件。
不足:课后作业部分布置的不是很明确
