“提高每个高中学生的生物科学素养”是实施生物新课程的核心任务。为完成这个核心任务,新课程倡导探究性学习,以此作为实施新课程改革的突破口。孙国华老师执教的《细胞膜——系统的边界》一课,在实施探究性学习、引导学生感悟科学方法等方面,做了有益且有效的尝试,对如何实施新课程、改变学生的学习方法,做出了很好的诠释。 “Enhancing the Biologic Literacy of Each High School Student” is the core task of implementing the new biology curriculum. To accomplish this core task, the new curriculum advocates inquiry learning as a breakthrough in implementing the new curriculum reform. The lesson of “cell membrane-system boundary” coached by Dr. Sun Guohua is a useful and effective attempt to carry out exploratory study and guide students ’understanding of scientific methods. He also made a helpful and effective attempt to implement the new curriculum and change the students’ learning methods. A very good interpretation.
