近年来,我针对初中学的特点,引导学生开展了建立小三库活动,对于丰富课堂教学、发展学生智力十分有益。具体作法如下: 1.建立小标本库有些小型动植物,如葫芦藓、小型蕨类、桃花、蝉蜕、贝壳、昆虫及生物化石等,便于保存和观察。我在教学中经常指导学生将它们采回来,制成小型标本,并注明名称、采集地和时间等,以备随时观察。学生在采集制做标本的同时对美丽的大自然也产生了浓厚的兴趣,观察和动手能力亦有所提高。 2.建立小信息库引导学生经常有意识的到报纸、杂志上去收集一些有关生物方面的知识、新闻、趣事等,并随时将它们记录和剪辑下来、汇集成册,以备查阅。使学生学会收集和贮存信息的本领,扩大知识面。 3.建立小经验库教师要经常结合课堂教学,引导学生有意识地去观察一些动植物或自然现象,并将观察结果记录下来,使他们不断积累实践经验,获得第一手资料,以备学习时参考和利用。为了引导学生开展好这一活动,我主要采取了以下几方面措施:(1)教师经常将自己建立的小三库拿到课堂上,让学生观看,起到启发、诱导、示范作用;(2)指导生物兴趣小组成员首先建立小三库,用他们的实际行动去影响其他同学;(3)经常结合课堂教学,将学生小三库中的“珍品”拿出来展示,使同学体会到建立小三库的重要意义。 (山东省掖县柴棚中学刘新德) In recent years, in response to the characteristics of junior high schools, I guided the students to set up a mini-three-pool activity that is very useful for enriching classroom teaching and developing students’ intelligence. Specific practices are as follows: 1. The establishment of small specimen library Some small plants and animals, such as gourd moss, small ferns, peach, cicada slough, shells, insects and biological fossils, easy to save and observe. I often instruct students in teaching them to be taken back, made of small specimens, and indicate the name, place of collection and time, ready for observation. Students also took a keen interest in the beautiful nature while collecting and making specimens, and their observation and practical ability also improved. 2. Establish a small information base to guide students to consciously to newspapers, magazines to collect some biological knowledge, news, interesting stories, etc., and keep them recorded and edited at any time, into a book for reference. To enable students to learn to collect and store information skills, to expand the knowledge. 3. The establishment of small experience library Teachers should often combined with classroom teaching, and guide students to consciously observe some of the animals and plants or natural phenomena, and observe the results recorded, so that they continue to accumulate practical experience, access to first-hand information for learning Reference and use. In order to guide students to carry out this activity, I mainly take the following measures: (1) Teachers often get their own small three libraries to get in the classroom for students to watch and play a role of inspiration, induction and demonstration; (2) Guide the members of the biological interest group to set up the mini-three libraries at first, and use their practical actions to influence other students; (3) often combined with the classroom teaching, show the “treasures” in the mini-three of the students so as to make the students realize the importance of establishing the mini- significance.
