技術试验在《通用技术课程标准》中占据了重要地位，这是因为它是一种重要的技术方法并具有巨大的教育价值。技术试验除了对技术活动本身具有不可缺少的重要价值外，还存在不可忽视的巨大教育价值。发掘技术试验活动的教育价值，是落实和实现通用技术中情感、态度和价值观目标的重要方面。
技术试验在教材中占有了相当重要的地位，教材中为此专门设置了“技术试验及其方法”一节和众多的“试验栏目”。通过学生经历这些试验活动，参与动手实践，培养他们的不断探究精神，体验解决技术问题的艰辛和感受获得成功的愉悦，养成百折不挠的意志和品质，培养实事求是、精益求精的态度。
在技术试验教学过程中，首先要激发学生对技术的好奇、爱好和追求，勇于不断提出“为什么”、“做什么”、“怎么做”，学生才能积极而主动地参与到技术试验活动中。要明确试验的目的和要求，了解试验的基本步骤，提醒学生在试验过程中要主动地进行观察。最后，要求学生以实事求是的态度写出简单的技术测试和技术试验报告。
在教学中，如何对待学生的试验失败、如何评价试验失败，成为教学中经常碰到的问题。要认识技术试验失败经常可能发生，引导学生认真分析试验中的失败原因，从中吸取教训，增长知识和技能，使其成为成功之母，并经历失败的磨练，培养良好的意志和品质。

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.
