生物科学是一门自然科学,是人们认识世界认知生命的基础。高中生物承担着学生客观认知自然科学规律和生命的重要任务。高中生物在高考的地位虽不及数理化,但仍旧处于不可或缺的地位。因此,相对较少的课堂时间和不能减少的学习任务之间的矛盾,只能从课堂效率入手。如何提高课堂效率,提高时间成绩的产出比是每个生物老师都难以解决又必须解决的问题。笔者从教学实践出发,重新讨论如何正确运用兴趣刺激,如何正确引导,探究,供同仁一起交流。
Biological science is a natural science, which is the foundation for people to know the world’s cognitive life. The high school biology undertakes the important task of students’ objective cognition of the law and life of the natural sciences. Although the status of high school biology in college entrance examination and mathematical and physical, but still in an indispensable position. Therefore, the contradiction between relatively few classroom time and irreconcilable learning tasks can only be started with classroom efficiency. How to improve the classroom efficiency and improve the time-to-output ratio is a problem that every biology teacher must solve and must solve. The author starts from the teaching practice, re-discuss how to correctly use the excitement of interest, how to properly guide, explore, for my colleagues to exchange.
