资源描述

1、1新型玻璃教学设计之 1第一课时教学目的:1、学会正确读写本课生字新词。2、朗读课文,整体感知课文,初步了解课文内容。教学重难点:学习生字词,整体感知课文,初步了解课文内容。教学过程:一、导入新课玻璃是我们日常生活中常见的东西,但是玻璃的种类不仅仅是我们见到的最普通的那种,还有许多新型的玻璃,你知道有哪些吗?它们又有什么用途呢?今天我们就学习几种新型玻璃。二、板书课题提问:“新型”是什么意思?三、学习生字词1、注意读音:殊、即2、字形:碎。3、形近字同音字:4、教师结合课文,理解文中的词语:陈列、博物馆、企图、犯罪、特殊、即使。四、指导学生朗读课文,整体感知课文。学生自读课文。思考:这一课介绍

2、了哪几种新型玻璃?教师板书:夹丝防盗玻璃,夹丝玻璃,变色玻璃,吸热玻璃,吃音玻璃。提问:课文的主要内容是什么?教师总结:全课介绍了五种新型玻璃及它们的作用。第二课时一、检查学生朗读课文。二、学生自学课文,思考课文共介绍了哪几种新型玻璃,它们的特点,作用是什么?在文中画出。三、学生分小组交流,并填表。2四、全班交流并展示图表五、结合表格内容,读课文,概括段意。练说几种新型玻璃的自述。六、练习朗读一至五段。七、学习第六段,理解“正在、将会”两个词。八、提问:这句话你怎样理解?对全文起什么作用?九、教师总结全课。学习了本课我们应在当今科技飞速发展的情况下,努力学习科学文化知识,以后为科技事业的发展作出贡献。
