生物是一门实验性极强的学科,实验效果的好坏关系着学生对知识的掌握程度,纵观现今的生物实验课程,大多数是建立在前人总结的基础之上,学生仅仅来做一些验证性的工作,这不但大大降低了学生学习的积极性,而且这些实验结果大多都在设计者的预料之中,束缚了学生创新能力的发展。随着新课改的进行,我们要改变这种局面,在初 Biology is a highly experimental discipline. The effectiveness of experiments is related to students’ mastery of knowledge. Looking at current biological experiment courses, most of them are based on previous studies and students only do it. Some verification work has not only greatly reduced students’ enthusiasm for learning, but most of these experimental results have been anticipated by the designers and have constrained the development of students’ innovative ability. With the new curriculum reform, we must change this situation at the beginning
