【教研】探索python循环之美-----for语句专题校内公开课

教育让师生共同成长

“学生是学校存在的第一理由，二外为未来培育人才”

讲好学校故事，让社会重新发现二外！

分享从指尖开始！

编程赋能成长，代码点亮思维。近日我校信息技术组章飞凤老师执教了一节校内公开课，课题是《Python循环结构-for语句》，Python循环结构for语句处于“顺序结构”和“分支结构（if语句）”之后，是程序设计三大基本结构的最后一环，也是编程入门的核心知识点之一。
本课内容主要是以画十个同切圆这个案例贯穿整个课堂教学，从顺序结构引出for循环语句,用通俗易懂的语言讲解for循环基本概念、语法格式、执行过程，并切入range函数，讲解该函数格式及运用，强调简洁性是编程的灵魂，学生也在不知不觉中完成了新课知识点的学习。本节课，章飞凤老师结合我校的学生实际来因材施教，将for循环语句这个比较难的知识点掰开揉碎了来实施教学，由浅入深、层层推进，课堂生动易懂、讲练结合，帮助同学们建立编程逻辑，掌握循环编程核心技能，提升了同学们信息科技核心素养，为后续编程学习打下坚实基础。
