电脑游戏的利弊
引:
电脑游戏包含两大类:硬件游戏和网络游戏,而绝大多数的学生喜欢玩网络游戏中的角扮演类。由玩家们控制自己的角在虚拟的世界中闯荡,体会另一种人生的苦与乐。这正是网络游戏如此受欢迎的原因,使它能在较短的时间内风靡全球,然而正是这样一个虚拟世界给学生们带来了许多利弊。
一、电脑游戏导致学业荒废:
虚拟世界是非常适合学生的,但学习压力大和逆反心理等因素导致了他们选择了一个发泄的空间——虚拟空间。他们可以摆脱现实生活中的一切,去做平时在现实中做不到的事情。这使他们越陷越深,学习成绩自然大幅下降。
二、电脑游戏损害学生的身心健康:
(1)长时间使用电脑危害学生们的身体健康:电脑显示器和电视机一样,在产生图象过程中,
会产生对人体有害的射线与电磁场,青少年正处于发育阶段,大脑极易受到损害,长期在电磁波辐射下,会使血液速度减少,严重者还会导致失明症、白血病、乳腺癌等病症。
(2)心理疾患不容忽视: 许多学生因为沉迷于电脑游戏而患上网络成隐症,网络疏离症等新型精神疾病。严重者还可能玩游戏受到刺激,没有得到及时的疏导,从而导致间断性精神失常。
(3)诱导学生犯罪,学生们沉迷于网络游戏中难以自拔,用身上的零钱难以维持后发展为向父母骗钱,再发展为向低年级学生,最终发展为偷窃、。因此,说一些电脑网络游戏对学生们的危害不亚于,人们将其比做“电子”。所以学生应该好好控制自己,不能沉迷与网络游戏。
青少年最喜欢的电子游戏中有50%带有暴力内容。暴力电子游戏增加了游戏者的攻击行为、攻击认知、攻击情感、生理唤醒。调查研究了11~15岁男孩玩网络游戏的体特征,发现其网络游戏体具有层级性,且各体之间经常发生言语或身体冲突。
  有专家认为玩暴力电子游戏可能会减少游戏者对受害者的同情并使其更倾向于把周围世界
看作是一个危险的地方。1999年美国哥伦比亚高级中学校园击案之后,人们开始关注电脑游戏这一新兴的媒体暴力形式。很多研究证明了游戏中的暴力会增加人的攻击性。

1)造成心理疾患。儿童期的孩子身心发育都不成熟,如果长期沉溺于电脑游戏,对他们逻辑思维能力的发展是十分不利的,并且在情感上会对游戏、网络虚拟的世界产生眷恋和依赖。这种情况在独生子女身上表现得特别突出。他们本来人际交往就少,独立生活能力也比较差,更容易被精彩的虚拟世界所吸引。长期打电脑游戏的孩子,情绪不稳定、易怒、易沮丧,变得喜怒无常。

2)易产生攻击行为。电脑游戏的内容大都是战争、打斗、扑克电子游戏的利与弊、麻将之类,其积极的教育意义十分有限,而它的消极内容却往往把孩子引上邪路。有的孩子在学校里模仿游戏打斗方式向同学大打出手、拉帮结伙、玩世不恭、胸无大志,荒废了学业,甚至走向犯罪道路。

3)损害眼睛,影响发育。孩子长时间近距离紧盯荧屏,这样会使眼部睫状肌处于紧张状态,造成眼球的肌肉疲劳,从而出现视力疲劳、视力下降等问题。另外,电子设备正常运转
都要释放大量的电磁波,这种隐形杀手,会使人头昏脑胀,恍恍惚惚,长此以往会使人的免疫功能受到不同程度的损害,破坏体内激素的平衡,影响孩子的身心健康,导致各种病症的发生。

4)降低学习的兴趣,影响学习成绩。

三、电脑游戏对学生们的利是显而易见的:
首先,可以改善身体和精神状态。学生们是一个特殊体。学生们的学习是很紧张的,在繁重的课业负担下,偶尔放松一下心情也是很有好处的。
其次通过适当的电脑游戏,可以提高大脑协调手、眼睛的配合。在很多游戏中,脑部可以得到锻炼。
结束语: 电脑游戏作为一种生活的调节剂,对于学生们的生活,还是有一定的影响。所以,这把双刃剑,我们不能完全否定它利的一面,也不能完全否定它弊的一面。而应该扬长避短,
利用它的优点为我们服务。然而,我们的家长还有很大一部分不能正确地认识电脑游戏,根据某项调查显示:80%的父母反对子女玩电脑游戏,因为他们认为玩游戏会影响孩子成绩,所以只要发现自己的孩子玩电脑游戏就阻止,没有因势利导应当疏堵结合,这样才有利于学生健康发展。
hen a child sits down in front of a computer, it is not only the material he views but the length of time he spends on the computer that can influence his total social, physical and mental well-being. Too much computer time, even on "educational sites," can have a profoundly negative influence on a child's overall health. Carefully monitored computer usage can be a great way to supplement a child's learning; however, with computers, moderation is key.
Computer Use and a Child's Physical Well-Being
It doesn't matter if a child is using the computer for learning or for fun. Excessive screen time is hazardous to a child's health. The greatest physical risk of extensive computer use is eyestrain. According to Dr. John Jacobi, eye doctors are seeing a "humongous increase i
n the need for both vision therapy and occupational therapy because two-dimensional visual experience without related motor experience doesn't set the necessary base."
Staring at a bright computer screen for hours on end can cause nearsightedness, blurred vision and a problem focusing. In turn, this can affect a child's ability and even desire to read. Eye problems resulting from prolonged computer usage hit children harder than adults because children are still developing physically.
Secondary computer-related health risks include poor posture, eyestrain, obesity, and repetitive-stress injuries, which have the potential to damage muscles, tendons and nerves in the hands, arms, neck and shoulders.
Computer Use and Developmental Problems
Too much time in front of the computer screen can hinder a child's ability to synchronize his visual sense with actual movements, which can in turn cause development delays. Children who spend too much time alone with their computer lack important social skills, ar
e more easily frustrated and have a tendency to be more aggressive than children who spend less than an hour a day in front of the computer.
Computers vs. Active Play
Active play is crucial for a child's development.girl /child playing/climbing ladder image by L. Shat from Fotolia
Perhaps the greatest concern about the overuse of computers in homes and in schools is that it interferes with a child's active playtime. Active play is necessary for overall physical health and greatly reduces the risk of childhood obesity. There is mounting evidence that links the reduction of active play with a series of mental disorders, including depression, as active play provides a way for a child to relieve unneeded stress.
Computers as Learning Tools
When used in moderation, computers are still useful tools for learning. Since the advent of computers, students' nonverbal intelligence scores on tests like the Raven Progressive Mat
rices have greatly increased. Computers help kids better understand visual images like diagrams, graphs and grids.
