生物教学一定要理论联系实际,如果不注意联系实际,仅作空洞的说教,教学效果是不会好的。为此,我在生物教学中,注意了充分利用学校的实验设施,根据课文的内容尽可能多地开设学生实验.如在讲第一章原生动物门时,组织学生采集、培养草履虫,之后再指导学生用放大镜、显微镜观察草履虫的形态结构,运动和应激性等生理活动.在讲第二章腔肠动物门时,带学生到塘边采集水螅,并用放大镜观察水螅的形态结构.另外还结合课文 Biology teaching must be theory and practice, if you do not pay attention to contact with practice, only for empty preaching, teaching effectiveness is not good. For this reason, in biology teaching, I paid attention to making full use of the experimental facilities of the school and setting up as many student experiments as possible according to the content of the text, such as when I was talking about the first chapter of the native animal door, organizing the students to collect and cultivate Paramecium Then guide the students to use magnifying glass and microscope to observe the morphological structure, movement and stress of Paramecium.In the second chapter coelenterate door, take the students to the pond to collect the water 螅, and observe the morphological structure of the water 螅 with a magnifying glass.
