问题 问答题

小杨在数学课上的表现一直不佳。当老师在课上布置练习的时候发现小杨对应用题的理解毫无进展。 “加油,小杨。我知道你能做出这道题的。”老师在小杨耳边低语,“好好花上几分钟仔细阅读题目,然后把题目分解成好几部分,等一下我会过来看看你做得怎么样。” 几分钟后,老师回来问道:“怎么样” 小杨还是不太清楚,但是显然他已经开始摸到了问题的关键,并开始动手解答,他说:“他们想知道这单价降低的百分比。”“很好,你还知道了些什么”老师笑着说。 当小杨开始解释他对问题的理解时,老师不断地问相关的问题让他回到合适的思路上来。当他终于解决了问题后,老师笑着说:“太棒了,我知道你很努力,你现在再重新看看我们是怎么一步步地解决这个问题的,过几分钟,我会再来看看你最终的解答,好吗” 最后,小杨自己解答了这道题。 请分析老师对学生学习动机的影响。

答案

参考答案:

解析:在这个例子中,老师首先鼓励小杨试图自己解决这问题,然后,她使用引导的方式让小杨自己努力解决问题,更重要的是,提供明确的证据证明在自己的努力下,他同样可以取得不菲的进步,并最终把问题解决。由此可以看到,老师对学生的自我效能感具有很强的影响力。具体表现在: (1) 表扬和批评。适当的表扬和批评对学生的学习活动予以肯定或否定的强化,从而巩固发展正确的学习动机。一般来说,表扬、鼓励比批评、指责能更有效地激励学生积极的学习动机,因为前者能使学生产生成就感,后者则会挫伤学生的自尊心和自信心。例子中的老师鼓励、引导学生自己解决问题,达到了激发学生学习动机的效果。 (2) 归因表述。归因表述是老师对学生成绩原因的一个评述,它将影响学生对自己能力的信念。当一个学习者刚刚取得某种进步时,把进步归因于努力是必需的,这能增强学习者的学习信心。例子中的老师把学生的进步归因于努力,对学生的自我效能感有很大影响,极大地激发了学生的学习动机。

In the last 40 years the bottled water industry has gone from a business prospect that few took seriously, to a global industry worth billions of pounds. The commodity itself remains simple. The way we think about it has changed fundamentally. Water is natural, pure and sourced at minimal cost. Its real value lies in its marketing and branding. "I think bottled water is the most revealing substance for showing us how the global capitalist market works today," says Richard Wilk, professor of anthropology at Indiana University. "In a sense we’re buying choice, we’re buying freedom. That’s the only thing that can explain why you would pay money for a bottle of something that you can otherwise get for free. "

41. ______

Through a confection of advertising and marketing, bottled water has become one of the biggest success stories in the modern food and beverage industry. "The demand for bottle water has grown exponentially in the last few decades," says Dr. Peter Gleick, author of Bottled and Sold. "It’s doubled, it’s doubled again and it’s doubled again. And the bottle water companies see enormous markets not just in the rich countries but also in the poorer countries. "

No actual variety

Some people think that bottled water is the high point of global capitalism, particularly the people in the bottled water business. "I think bottled water actually represents a kind of caricature of the global economy. It provides people in the developed world with 20 or 30 varieties of something for which there is no actual variety," says Charles Fishman, author of The Big Thirst.

42. ______.

At the beginning there really was no variety and the bottled water phenomenon began with one brand. Perrier (佩绿雅,矿泉水品牌) was a triumph of advertising, creating a brand that was to define a generation. At the heart of the campaign to make the brand popular was Richard Wheatley, of the Leo Burnett advertising agency between 1979 and 1994. "Perrier popularised bottled water," he says. "It made it acceptable, more than acceptable, it made it... desirable. " But it was not an instant success. When Perrier UK was looking to increase its sales in the early 1970’s, it faced a skeptical public. Many questioned why anyone would buy water when you could get it free from the tap.

43. ______.

Faced with obstacles, Perrier turned to advertising with a campaign that was to change our consumer landscape for ever. The campaign was a marketing coup and sales went through the roof from 12 million bottles in 1980 to 152 million by the end of the decade. Perrier was no longer just a bottle of water. The marketing and advertising teams had established a crucial emotional link between the product and the consumers. "Perrier became a badge," says Michael Bellas, chairman of the Beverage Marketing Corporation. "When you held a Perrier bottle up, it said something about yourself, it said you were sophisticated, you understood what was happening in the world. It was a perfect beverage for the young and coming business executives, the trend-setters. "

44. ______.

In an age of instant gratification, still water in portable bottles provided what people needed, exactly when they needed it. "People in general are more and more time pressed," says Mr. Fishman. "We don’t cook our own meals any more, we eat prepared foods of all kinds. And there’s nothing more appealing than a bottle of cold water at a moment when you’re really thirsty. But I think bottled water is one of those products that on many occasions when people buy it, what they’re buying isn’t the water so much as the bottle. That is the package and the convenience at that moment. "

45. ______.

When people bought this convenience, what they were really buying was Polyethylene Terephthalate, or PET, the single most important innovation in the industry’s history. Strong, shatterproof and a highly valued form of polyester, PET is a by-product of the oil industry. It is now utilised in the packaging of everything from pharmaceuticals and soap, to ready meals. In years to come, the environmental impact of PET would haunt the industry and raise questions about its very survival, but in the 1990s this was a revolution. According to Mr. Bellas it was behind the subsequent incredible growth of the industry. "Starting with the introduction of the small premium PET waters, the category started to explode," says Mr. Bellas. "The bottled water industry before PET on the list of all beverage categories was number seven. With the advent of PET, water jumped to the number two spot, behind carbonated soft drinks. "

By branding and marketing water, bottled water has been transformed from something that many of us took for granted into a product that now makes billions for global multinational companies.
