通用技术教学与职业技术教学的不同之处,在于它十分重视一般技术思想和方法教学。一般的技术思想和方法可以迁移到不同的技术类别中去运用,甚至可以迁移到其他领域。技术的思想和方法是通用技术课程的精髓,有利于提高学生的技术素养,它为学生打开技术大门提供了一把钥匙,有益于学生的终身发展。
在技术与设计教学中,一般的技术方法主要有:技术设计的一般过程方法、模型的方法和技术试验方法。在必修教材中技术设计一般过程的编写采用了“先总—后分—再总”和循序渐进、逐步深入的教学策略,所以在教学中要正确领会编写意图,把握教学要求,合理分配教学时间,避免急于求成或一些没有必要的重复。
Dear Dad,
Today is fathers day, for so many years Ive been seekig a way to express my heartfelt thanks for all you have done for me. Here comes it!
Thank you for always being there sharing my life when I need you most. Whenever I encounter difficulties, I never feel alone and vulnerable, because you will keep me on the right path. Im blessed to have you.
Thank you for offering me education and teaching me how to be a man. You always inspire me not by words, but by what you have done! Your efforts in the work, your loyalty to your friends, your responsibility for the family and your persistence in the life have already set me good examples in my own life.
Thank you for always appreciating my work, no matter how tiny it is! You have made me realize that its capacity not scores that really counts.
Dad, I love you and I will love you forever!
Yours beloved,
Li Ming
为使必修教材更好地适应课堂教学实际,教材内容按照学生的认知规律和“最近发展区”教育理论进行设计。引领学生积极地参与技术学习和设计活动,转变学习方式,让他们自主地建构技术的基本知识和基本方法。
在每节课前认真研读学习目标,指引学生把握学习方向,掌握需要达到的最低学习要求。生动而简洁的导入学习主题内容,通过案例分析、讨论、思考或辩论等栏目,创设学习情境,搭建一个师生间、学生间可以互动的平台。引导学生去理解、分析主题内容,并在理解的'基础上自主地建构技术知识,“同化”学习内容,通过练习中的“做中学”的方式动手实践,实现从“无形”到“有形”的转变,进一步的“消化”和巩固。在每章的最后,通过综合实践活动,将学到的知识、技能、方法综合化,并拓展和延伸,使学生学到的知识、方法、技能“综合化”,实现“顺应”。
同时,教学内容中的实例、设计和项目都应紧贴学生的生活实际,如教材中以每家每户都使用的灯具作为横贯教材的前后内容的一个主要教学载体。由于灯具已经为学生熟悉,所以在教师的引领下,学生可以从现有水平比较容易地完成一个设计任务,达到一个解决设计问题的新水平。
I'm so glad to receive your invitation.But I'm so sorry for you,I'm afraid that I can't go to there,because I have something important at Satarday.
Thank you invite me,but I have to go to the art class and dance class,both them make me so busy on Satarday.And at night,I must go to my teacher's home to do my homeworke.So it's so pity that I can't attend this actiity.Tank you again for your invition,I hope you can tell me something about this activity by letters.
