一、实验操作在生物教学中的作用初中生物是以实验为主的教学,通过提出问题—作出假设—制订计划—实施计划—得出结论—表达交流等过程。为搞好实验教学,培养学生的实验能力,我主要通过以下方式进行:1.让学生参与准备实验,培养其参与意识和动手能力如观察小鱼尾鳍血液流动,根据学生大多居住乡村的特点,布置学生利用业余时间捉小鱼,进行实验准备,既增强了学生的参与意识,又培养了学生的实践能力。2.做好演示实验,培养学生观察思维能力充分发挥教师的主导作用,利用演示实验生动、直观、形象等 First, the role of experimental operation in biological teaching Junior biology is based on experimental teaching, by asking questions - make assumptions - the development plan - implementation plan - concluded - the exchange of expression and other processes. In order to improve the experimental teaching and cultivate the students’ experimental ability, I mainly do the following: 1. Involve the students in preparing the experiment and cultivating their participation awareness and practical ability. For example, observing the blood flow of the caudal fin fish, according to the characteristics of most rural students living in the village, Disposition of students to use their spare time to catch fish, experimental preparation, not only enhance the awareness of students involved, but also cultivate the practical ability of students. 2 do a good job of demonstration experiments, training students to observe the thinking ability to give full play to the leading role of teachers, the use of demonstration experiments vivid, intuitive, image
