阅读下列案例,并回答问题。

  地理课上,为了使学生理解有关经纬线的概念和意义,某老师说:“在浩瀚的太平洋上,一艘远洋轮船出现了严重的故障,在自救无果的情况下,船长拿起电话,向总部求救。如果你是船长,你怎么说呢?”

  一学生作打电话状:“喂,总部,我们出事了,快来救我们。”

  “我是总部,请报告你们的位置。”教师追问。

  该生迟疑了一下,小声回答了一句:“我们在太平洋上。”

  他的回答引起了哄堂大笑。老师问:“同学们为什么笑呢?”

  “太平洋那么大,到哪里找呢?”学生回答道。

  “是呀,救援人员怎样才能找到在太平洋上出事的船呢?”

  “应该报告船的准确位置!”于是老师把“如何在地球上确定某一位置”的问题抛给学生来讨论。在讨论中,学生们从探讨如何描述自己的座位,到街道门牌号;从电影票上的座位号,到平面直角坐标系……

  就这样,关于经纬线、经纬网的概念和意义被学生们理解了。

问题:该教师的教学突出体现了哪个教学原则?为什么?试结合本案例谈谈该原则的贯彻要求。

正确答案及解析

正确答案
解析

(1)该教师的教学突出体现了启发性教学原则。启发性教学原则是指在教学活动中,教师要突出重点,深入讲解,同时要调动学生的主动性和积极性,引导他们通过独立思考,融会贯通地掌握知识,发展能力。该教师为使学生理解有关经纬线的概念和意义,先抛出轮船在大洋中出现故障如何求救的问题,吸引学生们主动参与进来,从解决这一具体问题出,引申拓展,进而理解经纬线的知识。这一过程符合启发性教学原则。

  (2)启发性教学原则的贯彻要求是:

  ①加强学习的目的性教育,调动学生学习的主动性。

  ②教师的讲授应抓重点、难点、关键,“少而精”,起到“点”和“拨”的作用。

  ③设置问题情境,启发学生积极思维。

  ④培养学生良好的思维方法。
