随着新课改的不断深入,生物教材不断改进和创新,越来越贴近实际生活和适应新时期的要求。然而,生物实验内容却没有多少变化,有的内容还操作复杂或难以达到最佳效果。本人对一些内容进行了多次改进,不断推陈出新并在实验教学上使用,收到了良好效果。现提出一些思考和建议与同行们共享。 With the continuous deepening of the new curriculum reform, biological textbooks continue to improve and innovate, and become closer to real life and adapt to the requirements of the new era. However, there is not much change in the content of biological experiments, and some content is also complicated to operate or difficult to achieve the best results. I have made several improvements to some of the content, constantly innovating and using it in experimental teaching, and received good results. Present some thoughts and suggestions to share with your peers.
