初中生物学科列入中考计分的行列已有多年了,学生和家长对本学科日益关注和重视。但多个学科的繁重学习任务给学生很大负担,使学生平时对本学科的学习不到位,常有“临时抱佛脚”的色彩。平时不扎实的基础给会考复习增添诸多困难。如:(1)对生物学科各主题的内容半生不熟,难记而易忘;(2)对知识间的过渡和相互关系的区分度差、易混淆;(3)对一些抽象思维的理解缺乏深度,如光合作用和呼吸作用的实质、意义及其之间的关系;又如对人体的各系统的结构和功能的学习需要抽象思维,学习时可依据较直观的示意图,但抽象与直观之间又有较大的差别。 Junior high school biology has been included in the ranks of senior high school entrance examination scores for many years, students and parents increasingly concerned about the subject and attention. However, the heavy task of learning in multiple disciplines greatly imposes a heavy burden on students, making students not usually able to learn from the subject and often has the color of “temporary embrace”. Usually not a solid foundation for the exam to add a lot of difficulties. Such as: (1) the content of subjects in biology is half-baked, hard to remember and forgetful; (2) the distinction between knowledge transition and interrelationships is poor and confusing; (3) the depth of the understanding of some abstract thinking is lacking , Such as the nature and meaning of photosynthesis and respiration, and the relationship between them. In another example, the study of the structure and function of various systems in the human body requires abstract thinking and learning can be based on more intuitive diagrams. However, between abstraction and intuition There is a big difference.
