通过创设问题情境提高生物课堂学习效率——“神经调节的基本方式”一课的教学设计与体会

To improve the efficiency of biological learning in class by creating problem scenarios

总结了利用创设问题情景在"神经调节的基本方式"一课的教学设计和体会。初一学生生活阅历较少,思维较简单,课堂上提出的问题范围不要过大,不要过于抽象,使学生不知从何思考,最好把问题分解成几个小问题,使问题具体化,符合学生的认知规律,利于学生思维的发展;学生的思维发展是有层次性的,教师作为学生学习活动的组织者、促进者,面对不同的学生同一问题需要教师具备灵活多变的问题策略,循序渐进的引导学生分析问题、解决问题;一节课创设问题情景形式要多种多样,不能就问题解决问题,要注意新旧知识的联系或者区别,知识的承上启下的作用等方面。

The author summed up the issue of the use of scenarios in the creation of ＂a basic form of neural regulation＂ of teaching a lesson in design and experience.First,students experience the first experience of living less than a simple way of thinking,There is a level of development of,teachers of students learning activities as organizer,facilitator,students are confronted with different problems to be the same teachers should have the issue of flexible strategies.Step-by-step were guided students to analyze and solve problems;experience of the three classes is to create a form to a variety of problem scenarios,the problem can not solve the problem.It is necessary to pay attention to the link the old and the new knowledge or the difference between the role of connecting knowledge and so on.
