培养学生的创新精神是技术设计教学的重点。设计是技术的核心,技术设计也是培养中学生创新精神和创造能力的有效教学载体,是通用技术课程的一个闪光点。
教材中的技术设计内容是根据《通用技术课程标准》为高中学生精心编制的一般设计过程与方法。所以,在教学中要紧紧把握一般技术设计过程中的核心、关键和方法,积极组织学生全员性和全程性参与,让他们亲历设计方案的构思过程、方案转化为模型的过程、技术试验的过程、交流和评价过程等技术设计过程,并从中体验和领悟技术设计的本质。
改变“重视操作训练,轻视创新设计”的旧的技术教学观念,大力加强学生的设计活动。教师要采取有效的教学方法,诱导启发学生构思,启迪学生的发散性思维活动,鼓励大胆创新,指点学生从人、物和环境三个方面系统地进行设计分析,不断地促进构思的发展,形成多方案的设计思路,通过比较、权衡和决策,产生技术设计方案。
教学中特别要重视多方案的形成,它是衡量技术设计教学是否成功的一个重要标志,力求避免全班只形成千篇一律的结果。
“山回路转不见君,雪上空留马行处。”课本上岑参诗句里的别离唯美而凄凉。一首写别离的小诗,把我的思绪牵往封尘的记忆……
我能记住的最早的别离,是四岁刚上幼儿园的时候。尽管很模糊,但依稀记得自己抱着妈妈的腿大哭。连续好几天,都是在老师的耐心抚慰下逐渐平静。直到某天,我突然明白我的哭喊都是无用功,我总要步入陌生的环境,而且别离不代表失去。我接受了和母亲短暂的`别离。这一课,我学会了独立。
到了小学毕业,我要和熟悉的同学们别离。第一次毕业的味道是苦涩的。同学们眼含泪光,手牵着手,哽咽地唱着:“长亭外,古道边,芳草碧连天”等离别之歌。大家回忆过往同老师、同学们的种种,围成一圈讲述着小学六年的难忘回忆和奇闻趣事,别离的苦涩味道中,泛出一抹回甘。我们都感慨时光流逝飞快,还没来得及慢慢品味就已成往昔。我们懊悔惋惜着那些被我们得过且过、狼吞虎咽地浪费的时光。这一课,我学会了珍惜当下。
初中第三年,在大家都忙着备战中考时,我离开了熟悉的城市。和小学不同,这回是我和所有同学的别离。我心中难免暗自神伤。同学们纷纷递来卡片和信纸,过来安慰我,以后常联系。大家都为我加油,祝福我考上理想高中……回到家,翻看着同学们的留言,到了最后一张,是我最好的朋友写的:“海内存知己,天涯若比邻。”我的心一下变得明亮起来,抬起头,有了看向更辽阔的远方的勇气。这一课,我学会了豁达。
别离似雨,浇洒在人生的每一个角落,每一滴雨水都在打磨着我心灵的雨伞,每一滴雨水都是一位小老师,教导我学会坚强、独立和珍惜……
别离,是人生的必修课。
Emerging from the cartoon is an eye-catching scene that the parents are willing to have a second child, while their only child do not agree because of his worry that he doesn't want to have another child, even his own sibling, share toys with him. Simple as it is, the symbolic meaning revealed is profound and thought-provoking.
We are supposed to place our attention on, instead of its funny appearance, the implied meaning of the cartoon: as the overall second-child policy expands throughout China, some only children are so selfish that they cannot accept the second child in their family. What can account for this undesirable situation? For one thing, they, as the only child at home all the time, have no awareness of sharing what they like with others due to the fact that all the family members give their love to the only child. As a result, when faced with the problem of whether they are willing to have a sibling, their first response is to refuse it. For another reason, some couples are eager to have a second child as soon as possible, which makes them neglect to communicate with their only child to let them realize the advantage of having a sibling companion in their childhood.
From what has been discussed above, it's safe for me to conclude that it is urgent to take some immediate and effective measures. What I recommend is that parents should let child know the importance of sharing with others, which is beneficial for them in future life. In addition, it's better for parents to have more communication with their only child once they want to have a second child.
