高层次的思考 4/10/2015



高层次的思考 4/10/2015

高层次的思考,简单而言,就是非背书的方式作答。给标准的答案。它是有经过个人思考后,有创意的,浓浓的个人主观看法和想法也符合客观/大家认同的。是有8-Wh1HWhat  / Where /When /Who /Whose /Whom/ Which / Why / How )的追问和探讨,尤其是Why How后的看法和想法 。这是有经过个人思考过程后的结论。

要有高层次的思考,个人就得广范阅读去获得各方面的知识以提高个人的认知。其实大部分的人每天的思考模式几乎都是高层次,只可惜,学校的[应试考试]就是那么[死板]严重的靠背书作答。要求标准作答。高层次思考也是logic 思考。是符合科学的。是可以验证的。也可符合时间的考证/time-tested 的。

Google search就打[高层次思考/Higher Order Thinking Skills]那里有的资料多到,我看个人根本承载不了的。现在有网络的方便和丰富的资源,个人只要有时间就可以上网去收集。太方便了。现在 学校要做的事就是怎么undo学生们依赖的习性。在师长有效的指引下从新学习如何独立和合群学习和找资料。这过程是有独立和互动思考。

是改变的时候了。也是时候解放老师和学生们了。第一件事,就是怎么减轻师生的工作量。如何[事半功倍]教学。这真的要全体的logic/高层次思考。就以[英文科]来讲,除了作文和造句,英文老师,可以把改簿子的工作交给学生[交换改]。这样他们就有第二次阅读作业的机会。同时,也可以减轻老师们重复的批改类似的错误。

英文文法或其他的作业练习,一年级学生都可以训练他们[交换改]。作文和造句老师大概可以稍微看一下和改一些。大概知道他们的问题之后是给他们看正确的文法结构和句子。还有一篇作文模范参考。把学生作文改到100%完美,有用吗?除了[交代和累坏自己]以外,这[改改改。。。]的活动,效果呢? 

要掌握好英语/文,第一,就是提供练习英文文法和发音的机会。这老师们可以做到100%的基本功。请问[单字]的收集,如果没有学生个别阅读,英文老师们可以为学生们做多少?统计一下有10%吗?,一个学生从幼儿园到STPM,这14/15年期间,一个学生单单在课堂上可以学到多少英文单字?

现在学生最大的问题就是[没有阅读]。所以他们对很多事情的认知是[有限]的。问高层次的问题:为什么[没有阅读]?看看这是否就是答案:[学校功课太多太繁重。放学后,还有很多补习课要去上。那里还有时间阅读?]再说,对很多家长来讲,阅读根本对拿好成绩没有直接帮忙,阅读什么?这是整体的问题。

这也是整体欠缺高层次教育思考的问题。很多时候,不管多高教育官位的就是欠缺logic高层次的思考。所以这样子的教育后果就是这种欠缺logic高层次的思考结果。高层次思考这句佛家名言:[因果之中,没有如果,只有必然。]。是的,是[因果和后果]。这么样奖赏As成绩的学生。结果,师长,父母和学生就往As成绩冲冲冲。。。。

不管学生个别差异天赋和嗜好,行/不行大家都管不了那么多了。就是这样的一个模式套全部。所以才有这样的结果和后果。看数目字:站直的[1]和平躺的[一]无法连接看到都是One/Satu。只认为站直的才是One/Satu.  这就是问题的症结。知识有限,认知又不足,高层次思考不用说了。这样的领导会有怎样的[结果和后果]。


教育的事,我相信校长和老师们对教学的知识和认知是前线和直接的。所以任何的新政策是有必要让各个校长和老师们参考讨论后才[算数]:可行%/不可行%。是教育部听从校长和老师们见解决定后才做做决定。绝对不是教育部决定[1]切,然后,不顾[1]切执行。教育部只能提议,不能决定。 这我们的教育才有起死回生的机会。有机/有生命力的教育是高层次思考的因果和后果。

Princeton's School of Hard Knocks

Virginia Postrel

Worrying about the angst of high-achieving students has become a minor industry. “America’s culture of hyper-achievement among the affluent” has led to suicides, depression, and anxiety among college students, suggested a July New York Times feature. “These cultural dynamics of perfectionism and overindulgence have now combined to create adolescents who are ultra-focused on success but don’t know how to fail,” wrote Julie Scelfo.  The rhetoric of concern barely conceals contemptuous disapproval.

In this popular narrative, America’s best college students are making themselves miserable trying to please pushy parents and grab lucrative jobs. They’re soulless grinds -- the products of insensitive parenting and a sick culture. This fable leaves no room for intellectual enthusiasm or the pride of seeing oneself as smart and accomplished. It assumes every activity these students pursue is instrumental, undertaken merely to look good on an application for the next stage in their upward climb. Their drive for success, it suggests, cloaks an ignoble lust for fame or money.

The moralism of this tale may flatter the tellers, but the story itself largely misses a deeper underlying struggle on elite campuses.

Intrigued by reports that my alma mater had initiated something called the Princeton Perspective Project, which aims to reduce student stress by puncturing a reportedly pervasive ideal of “effortless perfection,” I went to campus last April to investigate. Had Princeton students stopped griping about how much work they had and how little sleep they were getting? Had sprezzatura, the art of making difficult feats look easy, truly gone from a concept you learned in Renaissance history class to a quality most students possessed, or tried to?

I spent four days interviewing both students involved with the Princeton Perspective Project and others I contacted through social media outreach and personal connections. (Because the interviews took place at the end of last school year, I identify students by their class standing at the time.)

This sample wasn’t random or necessarily representative of the range of student experience. It was heavy on STEM majors and middle-class strivers, light on athletes and wealthy prep school graduates. In these ways, it resembled my own undergraduate circles, although with more children of immigrants and more women, both groups whose numbers have grown significantly in the three decades since I graduated.  But after repeatedly hearing the same themes, I came away with a better sense of why students feel stressed at Princeton and most likely at similar elite institutions.

Every January a great team loses the Super Bowl. Every April three of the Final Four go down. And every September, extraordinary students arrive at highly selective universities only to discover that one out of every two really will wind up in the bottom half of the freshman class --and one out of every five in the bottom quintile.

“I think most people come in knowing that they’re going to do probably worse than they did in high school, but there’s a very big difference between knowing that and actually getting back your grades at the end of the first semester,” freshman Bharath Srivatsan told me. “You may have thought Princeton was going to be hard, but it’s unlikely you thought you were going to end up in the bottom quintile. So when you see that, that’s very, very jarring.” (A fate that did not befall Srivatsan.) Since 2004, when Princeton embarked on a campaign against grade inflation, the university has told students which fifth of their class their cumulative grade point average puts them in.

Contrary to generational stereotypes, these students are not precious snowflakes who’ve spent their youth receiving participation trophies just for showing up. They’re genuinely impressive -- high achievers who’ve distinguished themselves, often in national or international competitions. They are so gifted and so diligent that they’ve rarely experienced obscurity or defeat before arriving as freshmen. They’re used to doing well, and to being known for their achievements.

“If you Google most of your friends, you’ll find them, and that’s really not normal,” said a senior chemical and biological engineering major, recalling the first-year practice of digging up news articles about friends’ high-school accomplishments and posting links on Facebook. It’s affectionate teasing, but also a reminder that “even before you do anything, even before you’ve taken a class, there’s already an expectation for you.” (Although she didn’t care if her friends recognized her, she was one of several students who asked that I did not use their names to protect them from search engines.)

Nor are these high achievers necessarily victims of overbearing parents. “Overwhelmingly they are putting that pressure on themselves,” said Alexis Andres, a residential-college director of student life and one of the administrators behind the Princeton Perspective Project, in which students share their struggles so that others know they aren’t alone. She recalled meeting with a student who needed to drop a course after health problems caused her to fall behind. The young woman was beside herself, crying “What am I going to tell my parents?” As Andres and the student’s academic adviser sat there imagining scary Tiger Parents, the student sobbed, “My parents are going to say it’s fine and not to worry and it’s no big deal -- and they’re not going to be mean about it when it is a big deal!” The drive of these students is intrinsic and tied to their sense of identity.

“Effortless perfection,” however, is hardly the norm. To the contrary, students described something akin to Parris Island. As freshman Ian Iverson put it, “the culture tends more towards, ‘I’m doing everything I possibly can and I’m almost at the breaking point and about to fall down, but I’m not.’” On an otherwise diverse campus, said a sophomore woman, “the common thread is that classes are difficult and people struggle with their school work.” Everywhere I looked, students were quite obviously working hard. And history professor Anthony Grafton told me that his classes showed little interest in sprezzatura when he taught Castiglione’s Book of the Courtier in the popular humanities sequence. It apparently wasn’t a concept they found resonant. (What engaged them was the role of women.)

The real problem, it turns out, is that students expect “effortful” perfection. Those who work hard and nevertheless get low grades or who don’t win a spot in their preferred extracurricular group assume everyone else is succeeding. (Just look at the happy pictures on their Facebook pages!) Confronting failure or rejection in one area, said Andres, they extrapolate “that their life has no meaning, that they aren’t going to be successful here, they aren’t going to be happy here.”

Surrounded by distinguished peers, freshmen in particular may experience a disorienting loss of identity. “It’s not just that you’re not the biggest fish in the pond anymore. It’s that there are so many other big fish,” said the chemical and biological engineering major, a top science student in high school who found herself near the bottom of the class at Princeton.  Once known as “the smart kid” or “the great musician,” students no longer find themselves so distinctive. “When everyone’s a nerd, you’re like, What am I?” she said.

Despite what you read in the newspapers, the primary source of this angst isn’t bad parenting or crass careerism. Instead, it’s simply that too many superb students with impressive extracurricular accomplishments now have a fair shot at the very best colleges. Widened horizons and increased financial aid mean that students whose equivalents a generation ago might have triumphed at the nearest state university or regional liberal-arts school now find themselves in the middling, or even bottom, ranks of the most demanding institutions. Meanwhile many of the legacy admissions who might once have provided an ample supply of students satisfied with aristocratic C’s are now the super-high-achieving kids of high-achieving baby boomers.

One of the seniors I talked to was a third-generation Princetonian. Tall, blond, and blue-eyed, he’d fit the casting director’s idea of the kid who cruised through admissions thanks to lower standards for WASPs with family connections. But real life isn’t the movies. He had in fact done graduate-level math research while still in high school. His dad, one of my college friends, had been a stellar Princeton student, Phi Beta Kappa with a passion for puzzles that made him an outstanding statistics major. The son was even better -- and so was his high-school preparation.

The result of all this excellence is that today’s most talented and driven students are learning some tragic truths earlier than their predecessors: To be genuinely ambitious is to fail, repeatedly and throughout your life, by reaching for goals you can’t quite attain. And in a big world, you are almost certainly not the best at whatever you care most about.
As a result, they face the existential challenge of discovering who they want to be and what makes them special while they’re still in college.

One of the recurring themes in my conversations with students was their need to find something to be “known for,” a way to “make a mark” or “stand out.” They quickly corrected any assumption that this was a quest for fame. “I think we know that with 5,000 kids here you can’t really have a reputation with the whole student body,” said freshman Ming Wilson. It’s a search for meaning and significance: a contribution uniquely one’s own.

When I asked what college is for, their answers were remarkably philosophical. “Starting to figure out and try to live the type of life that you want to live,” answered Wilson. “College is a time for people to choose who they want to become,” said senior Shawon Jackson, a two-term student government president and a driving force behind the Princeton Perspective Project. Choose, he emphasized, not “find yourself.”

“It’s almost like a holding pen for us, to wait those extra few years -- it’s a midway point in the process of growing up,” mused sophomore Mary Heath Manning, the Princeton Perspective Project’s chair. But at least at Princeton, she continued, the waiting isn’t as passive as that metaphor implies, because the school “provides so many opportunities to figure out what’s important for you in life.”

The chemical and biological engineering major I talked to sounded less like a recruiting brochure but made the same point. “I think it’s kind of good that Princeton breaks people,” she said, “because it forces people to think, What am I actually passionate about? Not, What is good for my future?” Despite her struggles, she had opted to stay in her demanding field because she genuinely loved the subject.

Learning to deal with defeat -- to take it seriously but not to find it crippling -- is one of the proverbial ways in which sports builds character. We take athletic disappointments as part of the game. We understand that even at the highest level not everyone can be the best. We expect fiercely competitive players to be frustrated, sad, and angry when they don’t win. We also expect them to get over it.

Building character is a horribly old-fashioned concept. Although it inspired their founders, secular universities like Princeton would never invoke the concept today. Explicitly or not, however, building character is still something they do.

The pain and struggles that generate so much public fretting are real. But unless elite schools start reserving a quarter of their slots for the unmotivated or unqualified, they’re also unavoidable. Wanting to excel is not a character flaw, and shouldn’t be treated as one in the guise of concern for students’ mental health. Ambitious students deserve the same respect we accord ambitious athletes.

  1. In a follow-up Q&A, Scelfo contradicted the thrust of her long feature, acknowledging that “there is no data indicating that suicide is more prevalent at elite institutions than at two-year or four-year colleges. In fact, college of any kind seems to be a form of protection against suicide.”
  2.  When I was a student, the male-female ratio was 2:1, which in my minority opinion is ideal. Today the undergraduate population is 51 percent male.
  3. She didn’t tell me about her high-school accomplishments; I Googled her, thereby demonstrating her point about search engines.

I guess we fare better when you dare to fail.  The ability to deal with disappointments in life should be seen a skill to acquire.

Go organic (copycat)



To build a greener economy, Bhutan wants to go organic by 2020

SATSAM, Bhutan (Thomson Reuters Foundation) - Farmer Phub Zam, 55, is in a hurry. Monsoon rains have hit her farm in Bhutan’s Paro valley and Zam is rushing to harvest her broccoli before crop is damaged.

"Of all my vegetables, broccoli is the most sought after," she said. “Each kilogram sells for 90 rupees ($1.40)."

That’s 15 to 30 cents more than broccoli imported from neighboring India. Zam gets the higher price because her produce is grown without the use of chemicals, making it healthier, more flavorful and more in demand.

"I apply organic manure that I compost right at home," she said. “The imported vegetables do not taste so good."

After decades of subsistence farming, Zam went organic four years ago. Now she grows 21 crops on her 1.3-acre farm — including grains, fruits and vegetables — and sells them, as well as homemade compost, to hotels, local vendors and nursery owners.

She earns 40,000 rupees ($600) per month, three times more than she made before, she said.

Zam’s success is part of Bhutan’s plan to support sustainable farming as one key to build a thriving “green" economy.

In 2011, the government launched the National Organic Program, which aims to make the country’s agriculture 100 percent organic by 2020.

By teaching farmers good organic farming practices and how to earn more money by growing organic produce, and by providing financial support, Bhutan hopes to reduce waste, decrease the country’s dependence on imported food, and ensure it remains climate-neutral, producing no more climate-changing emissions each year than its forests absorb.

Already praised by environmentalists for its low carbon emissions and heavy use of hydropower, Bhutan hopes to become even greener by showing that environmentally friendly farming can also make money.

CASH FROM TRASH
Zam’s switchover came when a team of officials from the agriculture ministry told her they were offering women farmers in her village free training in organic farming, including composting and selling the compost for a profit.

After attending a three-day training course, Zam started her home compost heap. Today, she sells about 60 kilograms of compost — made of grass, leaves, cow dung and sawdust — every two months to tourist resorts and other buyers.

Zam also uses the compost at her farm, including in the two greenhouses she bought and installed with an 80 percent subsidy from the government.

Before learning how to compost, she would end every harvest season with two or three truckloads of dead leaves and other organic waste that she would either burn or pay someone to dispose of.

"Now, from leaves to cow dung to chicken poop, everything is used," she said. “I have no trash, only compost."

Nedup Tsering, executive director of the government-funded Clean Bhutan project, which aims to make Bhutan a zero-waste country by 2030, notes that the country generates over 100 tons of garbage daily but has no centralized waste management program.

"We want citizens to practice the 5 Rs: Rethink, reduce, recycle, reuse and re-create," Tsering said.

THE HURDLES
According to Kesang Tshomo, coordinator of the National Organic Program, Bhutan faces some hurdles on its path toward fully organic farming, however.

"We have to be practical and consider the realities facing our farmers," she said.

One is that the country produces relatively little of its food. According to a 2014 study on food security by the Royal Bhutan College of Thimphu, less than 4 percent of Bhutan’s total land is under food cultivation, which is why almost 50 percent of the country’s rice is imported from India and Thailand.

To persuade Bhutan’s farmers to use organic methods, showing that the switch can lead to higher production is key, Tshomo said.

In June, officials announced that the government had so far provided 176 greenhouses to farmers and planned to install 650 more. It said its combined policies of pursuing organic farming and modernization — such as building greenhouses and fencing — had helped increase agricultural production 3 percent since the start of the organic push.

The government is banking on the Clean Bhutan Project to also help Bhutan keep its pledge to remain carbon neutral. Currently, the country’s carbon emissions rate is a negligible 0.8 metric tons per capita, according to the World Bank.

Promoting organic farming practices like composting is a “logical step towards the goal of remaining carbon neutral," said Peldon Tshering, chief strategist of Bhutan’s environmental commission.

Zam, the Paro valley farmer, supports the government’s plan to convert its farmers to organic agriculture. But for the project to succeed, she said, the government needs to help widen the market for organic produce.

Most of the hotels near her farm still mainly buy imported vegetables from India because they are cheaper, she said.

"If the government could convince people to buy from local farmers, it would help us a lot," Zam said. “I could sell all my produce within hours, without spending extra on driving a wagon from one market to another."

My comment:
Organic fruits, vegetables or poultry are free from pesticides, chemical fertilizers and they taste nicer or sweeter.  I have years of experience tasting to know the differences.
