科学教材中涉及的资料的收集、中长期观察、种植饲养、实地考查等教学内容,在一节课的时间里是无法完成的。因此,课外作业必然成为科学课堂教学的有效延伸,成为发展学生探究能力的重要一环。要想提高科学课外作业的实效性,应该做好这样几个方面:精心设计,提高作业的合理性;学会合作,降低作业的难度;优化整合,与其他学科作业相统一;有效平价,促进作业的延续性。
Scientific materials involved in the collection of information, long-term observation, planting and breeding, field test and other teaching content, in a class time can not be completed. Therefore, extracurricular assignments must become an effective extension of science classroom teaching and become an important part of developing students’ inquiry ability. To improve the effectiveness of science extracurricular homework, we should do a good job in several aspects as follows: elaborate design and improvement of the operation’s rationality; learn to cooperate and reduce the difficulty of homework; optimize and integrate with other disciplines; Continuity.
