2022年人教A版高中数学必修三1.2.3《循环语句》教案2 .pdf

名师精编优秀教案湖南省蓝山二中高一数学1.2.3 循环语句教案新人教 A版必修3 一 教材分析1 教材背景算法是新课标教材新增加的内容，从古至今算法思想都能在解决问题中得到体现，他不仅是数学及应用的重要组成部分，也是信息技术的重要基础。随着信息技术的发展，算法思想已成为数学素养的一部分,所以学习算法是非常必要的。2 本节课的地位及作用这部分的学习与前面的循环结构有密切的关系,也为后面学习算法案例打下良好的基础.二 重点难点重点:正确理解循环语句的作用难点:准确写出循环语句的两种形式三 目标分析1 知识目标教学目标（1）正确理解循环语句的结构；（2）让学生充分地感知、体验应用计算机解决数学问题的方法；（3）通过实例，使学生理解循环语句的表示方法、结构和用法，进一步体会算法的基本思想2 能力目标发展学生有条理的思考与表达能力，培养学生的逻辑思维能力.3 情感目标通过体验算法表述的过程，培养学生的创新意识，认识到计算机是人类征服自然的一各有力工具，进一步提高探索、认识世界的能力.四 学情分析算法这部分的使用性很强，与日常生活联系紧密，虽然是新引入的章节，但很容易激发学生的学习兴趣。在教师的引导下，通过多媒体辅助教学，学生比较容易掌握本节课的内容。五 教法分析采用“问题探究式”教学法，以多媒体为辅助手段，让学生主动发现问题、分析问题、解决问题，培养学生的探究论证、逻辑思维能力。六 教学设计1 新课引入顺序结构的框图可以用输入语句,输出语句,赋值语句来表示,条件结构用条件语句表示,循环结构我们必须用循环语句表示.2 新课教学问题 1:直到型循环结构的程序框图是什么？结论:该循环结构对应的循环语句的一般格式设定为：名师精编优秀教案问题 2:你能说明计算机在执行上述语句时是怎样工作的吗？先执行一次DO和 UNTIL 之间的循环体，再对UNTIL 后的条件进行判断.如果条件不符合，则继续执行循环体；然后再检查上述条件，如果条件仍不符合，则再次执行循环体，直到条件符合为止.这时，计算机将不执行循环体，而执行UNTIL 语句之后的语句.问题 3:计算 1+2+3+100 的值有如下算法:第一步，令i=1，S=0.第二步，计算S+i，仍用 S表示.第三步，计算 i+1，仍用 i 表示.第四步，判断i100 是否成立.若是，则输出S，结束算法；否则，返回第二步.你能利 用 UNTIL语句写出这个算法对应的程序吗？解答:问题 4:在下面的程序运行中，计算机输出的结果是多少？问题 5:当型循环结构的程序框图是什么？结论:该循环结构对应的循环语句的一般格式设定为：WHILE条件循环体WEND文档编码:CE10P5H8U8N5
