培养学生自学能力，是当前教学改革中的一个重要课题，是时代发展的客观要求。联合国教科文组织在一份报告中指出：未来教育应该较少地致力于传递和储存知识，而应该更努力寻求获得知识的方法（学会如何学习）。学生各校时间较短，单靠学校教给的知识是不可能完全满足今后工作 Cultivating students’ self-learning ability is an important issue in the current teaching reform and an objective requirement for the development of the times. In a report, UNESCO stated that education in the future should be less devoted to the transmission and storage of knowledge, and more efforts should be made to find ways to acquire knowledge (learn how to learn). Students’ time is short in each school, and the knowledge taught by the school alone cannot fully satisfy future work.
