去年5月的一天,收到河南教育出版社一位好友寄来的一本书,打开一看,是左加林老师的《初中代数的形象教学》。这本粉红色封面装帧典雅的小书,开头有我的教师丁尔升教授写的序,又切中我的本行,因此加班加点,一口气读完了她。此书写得不错,有很好的可读性,它的第一个标题《从柳卡问题谈起》就颇富启示性,继之而来的三章从代数双基教学的形象设计、代数题的形象求解和形象教学的几个问题几方面展开论述,把问题剖析得很清 One day in May last year, I received a book sent by a friend of Henan Education Publishing Co., Ltd., and opened it to look at the image teaching of junior high school algebra by Teacher Zuo Jialin. This elegant book with a pink cover and bounded by a book written by Prof. Dinger Sheng of my teacher was cut into my own business, so I worked overtime and finished reading her in one breath. This is well written and well readable. Its first title, “Talking from the Liuca Question,” is quite inspiring. The three chapters that follow follow from the image design and algebra of algebra-based teaching. The problems in image solving and image teaching were discussed in several aspects, and the problems were analyzed very clearly.
