【摘要】：课堂导入环节是生物课堂教学的重要步骤,合理的导入不仅能激发学生学习兴趣,而且还能激发学生探求新知识的欲望,开阔学生的思维,使整个教学活动有序进行,培养学生合作探究能力。但是,当前农村中学生物教师并不重视课堂导入环节,在教学中认为导入浪费时间,上课便直奔主题,或是长期采用单一导入方法(复习导入法)。而不重视导入环节的课堂,学生往往求知欲不强、课堂气氛不佳、课堂效果难以达标,这与有效课堂教学相违背。这表明农村中学教师需掌握一些对应的课堂导入策略进行有效教学。本课题基于课堂观察研究适合当前农村中学生物课堂导入的方法,理论研究了生物课堂导入的原则,根据这些原则和农村中学的特点设计课堂导入案例,并对现有的生物课堂观察量表进行修改,使其操作起来更具有适用性;同时,根据更改后的量表进行了三个导入案例的对照观察实验,并进行了量化分析,总结提出了一些生物课堂导入策略,为生物有效教学提供参考。本文主要研究的结论如下:1、生物课堂导入教学应当符合农村学生心理特点,具有针对性、启发性、趣味性、关联性等原则。2、多媒体+情景的导入策略,让学生与画面、与老师的语言产生情感上的共鸣,能引起学生的关注和激发学习的积极性。3、巧设试验的导入策略,富有启发性、趣味性的生物实验,不仅能激发学生的内部学习动机、唤起注意,同时有助于培养学生的观察能力和想象力。4、巧设疑问的导入策略,农村学生好问,设问能激发学生急于解惑的欲望,使学生及早进入最佳的学习状态,提高课堂的教学效率。
[Abstract]:Classroom introduction is an important step in biology classroom teaching. Reasonable introduction can not only stimulate students' interest in learning, but also stimulate students' desire to seek new knowledge, broaden students' thinking, and make the whole teaching activity proceed in an orderly manner. Cultivate students' ability to cooperate and explore. However, at present, biology teachers in rural middle schools do not attach importance to the introduction of classroom. They think that the introduction is a waste of time in the teaching, and then go to the subject directly in class, or adopt a single method of introduction for a long time (review the method of introduction). However, if we do not attach importance to the introduction of classroom, students often have a weak desire for knowledge, a poor atmosphere in the classroom, and the classroom effect is difficult to reach the standard, which is contrary to effective classroom teaching. This indicates that rural middle school teachers need to master some corresponding classroom guidance strategies for effective teaching. Based on the methods of classroom observation and research suitable for biology classroom introduction in rural middle schools, this paper theoretically studies the principles of biology classroom introduction, and designs classroom introduction cases according to these principles and the characteristics of rural middle schools. And the existing biological classroom observation scale is modified to make it more applicable. At the same time, according to the modified scale, three comparative observation experiments of imported cases are carried out, and the quantitative analysis is carried out. This paper summarizes and puts forward some biological classroom introduction strategies to provide reference for effective biology teaching. The main conclusions of this paper are as follows: 1. Biology classroom teaching should accord with the psychological characteristics of rural students, have pertinence, inspiration, interest, relevance and other principles. It has emotional resonance with the teacher's language, can arouse the students' attention and arouse the enthusiasm of learning. It can not only stimulate the students' internal learning motivation, but also set up the pilot strategy of the experiment skillfully, which is full of enlightening and interesting biological experiments. Arouse attention, at the same time help to cultivate students' observation ability and imagination .4, skillfully set up the question introduction strategy, the countryside student is easy to ask, the question can arouse the student anxious to solve the doubt desire, causes the student to enter the best study condition as soon as possible, Improve the efficiency of classroom teaching.
