一、发挥实验教学的作用,激发学生的生物兴趣实验教学的重要性不仅在于它对理论教学的完美诠释,更在于它能更好地激发学生学习生物的兴趣!在实验中,教师不要批评学生的失败,要鼓励他们找出错误的原因,总结失败的经验。这一过程不仅使学生对理论性知识有了全面而深刻的认识,同时还能推翻学生内心深处对生物这一刻板学科的终极态度,使其有了一个崭新的认识,兴趣是最好的老师,学习不感兴趣的科目像活在死水里的鱼,不能够长远。二、掌握步骤,规范操作,认真观察实验现象 First, to play the role of experimental teaching, to stimulate students’ interest in biology Experimental teaching is not only the importance of its perfect interpretation of the theory of teaching, but also it can better stimulate students interest in learning biology! In the experiment, teachers do not criticize students The failure to encourage them to find out the reasons for the error, summed up the experience of failure. This process not only enables students to have a comprehensive and profound understanding of theoretical knowledge, but also overthrows students’ ultimate attitude to the rigid discipline of biology and gives them a brand new understanding and interest. Teachers, learning subjects that are not of interest like fish living in stagnant water, can not be long-term. Second, grasp the steps, regulate the operation, carefully observe the experimental phenomenon
