自云南省进入高中课改后,面对先进的课改理念、全新的《课程标准》、众多的版本教材、复杂的学生情况和新增的知识板块,我们中的一些老师不知道该如何备课了。《算法》是“课标教材”的新增内容,它具有点多、面广、习题难的特点,而大多数教师缺乏算法思想和程序设计的基础,因此,备课时往往理解不透课标要求和学习目的,把握不准教学重点和教学关键,对教材内容不能进行合理的“再创造”和有效的整合,以至于常常将“算法”课上成了枯燥的习题课,甚至是“信息技术”课。作者以发表在《中学数学多媒体备课参考》的优秀课例为载体,结合自己的设计体会,介绍了一些常态化的、易操作的备课理念和方法。
Since entering the high school curriculum reform in Yunnan Province, facing the advanced concept of curriculum reform, the new “curriculum standard”, numerous version textbooks, complicated student situations and new knowledge sections, some of our teachers do not know how to prepare lessons It’s “Algorithms” is a new addition to “course materials”, which has the characteristics of more points, wider coverage and more difficult exercises. However, most teachers lack the foundation of algorithmic ideas and programming. Therefore, Class requirements and learning objectives, grasp the key teaching and teaching are not allowed to teach the contents of the material can not be reasonable “re-create ” and effective integration, so often “algorithm ” class became a boring exercise Class, or even “information technology” class. Based on the outstanding lesson examples published in “Mathematics Reference for Secondary School Mathematics”, the author introduced some normalized and easy-to-use ideas and methods for preparing lessons based on his design experience.
