信息来源是如此丰富且各具优点,那么如何选择合适的来源就显得非常重要了。首先可根据我们的需求并结合我们的实际情况去掉一些不合适的信息来源,再从最方便、性价比最好的信息来源开始尝试,如未达到目的,则需再做选择。 3、确定信息获取方法 由于信息来源的多样性,同样也决定了信息获取方法的多样性。 ①现场观察法 ②问卷调查法 ③访谈法 ④检索法(文献检索、网络检索) ⑤实验法 现在,利用计算机网络获取信息已越来越广泛了。(为讲解“因特网信息的查找”一节作铺垫。) 4、评价信息 即是以先前所确定的信息需求(信息的数量、信息的适用性、信息的载体形式、信息的可信度、信息的时效)为依据,对获取的信息进行评价。评价信息是有效获取信息的一个非常重要的步骤,它直接涉及到信息获取的效益。其实在获取信息的过程就一直在评价及挑选,即评价贯穿整个信息获取在过程。如不符合我们的需要就需作重新调整。 [思考与研讨]因特网上有我们需要丰富多彩的信息,现在我们利用因特网获取信息已越来越广泛了。那么,作为信息的接受者,我们该如何客观地评价来自因特网上的大量的信息呢? (参考《信息技术基础实践指导》16页) 可以从以下几个角度评价: 1、信息的权威性;(网站的主办者、作者、网页的制作和发布机构等信息) .edu是教育类网站,既可能是严肃的学术研究,也可能是学生随意制作的主页。 .gov或.gov.cn是政府网站,一般比较权威、可靠,不会随意发布不准确的信息。 .com或.com.cn是商业网站,最常见。在介绍自己的产品时往往会夸大其辞,所以要注意批判性地接受。 .net网络服务公司,为商业或个人用户提供服务。 .org一般是非赢利性组织,其观点可能带有倾向性。 2、信息的准确性;(文字是否通畅、统计表或图片是否清晰易读、文章、组织或个人资料的科学性等) 3、信息的客观性;(网站主办者、主要投资者、作者所属机构利益与文章内容是否有关联等) 4、信息的时效性。(网页或文档的创建日期、发布日期、最后修改日期等) 五、布置课后作业 (教案和教学设计)课件教学案例:信息获取的一般过程教育资源 教学资料人教新目标七下教案Unit 11 What do you think of&nbs 第二节 Unit 11 What do you think of game shows?
