Online education

We are faced with a dilemma. Online education is convenient and when is appropriately conducted can be a godsend for busy students. A lot of face to face education institutes actually puts their courses online, either as a supplement for those who may have missed a class or as a general community service for anyone who is interested in learning something. The acceptance of a qualification from purely online education institutions has been mixed. This article describes some of the misconceptions of online education. However the real issue is the prolific number of diploma mills that operate solely online. The quality of education again depends on the certification of the institute, be it online or otherwise.

Ken Robinson: How to escape education's death valley


Tuesday, 23 April 2013

Allow me to hit you at your head first...

My American readers,

Your country is not the greatest country anymore.


The only three things which USA is number one are:
1. number of people in the prisons (per capita),
2. number of adults who believe in a god (by percentage in developed countires), and
3. largest military budget - more than the next 26 combined.

The world is becoming more unequal, unstable and unsustainable. (That's from Bill Clinton)


UK was number one many years ago. She was called the Empire of Never Setting Sun. But she learnt not to be number one and her people is going on fine. As Clinton says so powerfully, we are all on the same boat. We all live on this planet and there is no second planet that we can go to if we mess this one up.

Let me drive this home with this:

To all my American readers, please DO something about this video

Please watch this very saddening video and then tell your government how you feel. Killing someone else is NOT a game and it is NOT for fun. Indiscriminately firing at civilians is WAR CRIME and should be treated as such even if it means you are reporting other Americans.

My father

父親出生於印尼,在祖父回鄉退休時,排行最小的六伯,七伯和父親,隨祖父回鄉。中學畢業後,任教於梅縣城中學。中日抗戰期間,投筆從戎,畢業於黃埔軍校,多次勝戰,官至少校。

在抗戰行軍時,爸爸看見路旁有ㄧ位垂死的老人向途人乞求ㄧ口水渴,心生憐憫,停下來給老人一些水,之後這老人堅持要父親收下了一只玉。爸爸隨手把這玉放在胸前的衣袋。那天晚上,父親發現胸前的口袋有ㄧ個被子彈打穿的洞,原來袋裡的玉救了父親ㄧ命。小時的我,常常見到爸爸和他的朋友間的互相幫助,一碗飯,兩份吃的事例,非常之多。

父親戰後隻身來到香港,本來計劃這只是ㄧ短暫的立足處,後來從鄉間接來母親,我們六兄弟姊妹也就在獅子山下出生。這個暫時的家,結果成了我們長大和發展的基地。

在我和芳妹出生之後,我們是住在荃灣山邊的木屋。在ㄧ個年三十日,媽媽到市場買年貨,您留在家中照顧我們,鄰居打反了火水爐,引起大火。槍林彈雨您不怕,我們兩兄妹的安危反而使您受了驚怕。您ㄧ手ㄧ個把我們救離火海。以後,爸爸ㄧ直對火災留下陰影。

爸爸,您以前照顧我們的生活瑣事,點點滴滴存在我們心裡。記得我們幼小時,您用手掌來量度我們的小腳,就可以替我們買得合穿的鞋。

我們也不能忘記您在黃大仙做生意時的那ㄧ段時光,您早上ㄧ天亮便開舖,下午我替您工作二三小時,讓您可以小休ㄧ會,然後您工作至午夜才回家休息。您為了我們,實在是太辛苦了。

父親,我們六兄弟姊妹在你和母親的愛護和關懷中長大了。我們成長的環境雖然品流複雜,但兄弟姊妹們都能以您作榜樣,奉公守法,抬頭直腰的為社會出一份力。我們家境清貧,爸爸沒有怨天由人,努力工作,教導我們要傲骨而不自棄,不貪不義之財,腳踏實地的做ㄧ個正直人。您對我們的教育,極為重視,您對我們的教導,嚴格中充滿慈愛。如果不是您和母親,我們那有今天。自小您已教導我們不可以坐在印有文字的書刊上,這種尊重文化的態度,我們是永不會忘記的。您絕不重男輕女,對我們每一個都ㄧ視同仁,這種公平的原則,奠下我們公平處事的態度。爸爸,多謝您。今天,我們每一個倘算學有所成,六兄弟姊妹共獲得七個碩士學位,正在不同的位置上為社會服務。爸爸,請安心,我們總算沒辜負您的期望。

爸爸給我的名字是榮忠,忠心的忠,弟弟榮信,人言為信的信。這也代表了爸爸的ㄧ生做人的宗旨。早幾天我們整理您的物件時,發現了您寫的ㄧ段話,「生活必須向前,生活就是ㄧ連串的學習,人活著必須向前,別以為能夠保持原狀,便可以萬無ㄧ失,久而久之,則變成了倒退。這是我的ㄧ點人生哲理,我ㄧ直都認為自己不足,學術與做人是感到貧乏,所以我就力求補救,不灰心,盡自己所能,這樣感到無愧於心。」這段話說明了您的哲理,使我們深深體會到做人不能氣餒,盡力而為,謀事在人,成事在天的道理。

爸爸,您其中ㄧ個最大的成就,是把我們這六條「化骨龍」撫養成人。您幼時盡孝,服侍祖父母,青年盡忠,為國效命,壯年盡愛,為我們的家奉獻了一切。爸爸,沒有您,沒有我們。我們不能和您的偉大相比,但會學您教導我們的方法來教導我們的子女,您的精神將永遠留在我們的心內。

爸爸,我們愛您,敬仰您。我們知道您以我們為榮,我們一直是以您為榜樣,以後我們還不會忘了您的教導,團結一起,盡我們之力,做我們應做的事。

Book Review: Interview with Gods


If you read this book as a novel, the plot is too simple - a group of friends (members of a non-political, non-violence ecologically focused group called One Planet) were contacted by "External Consciousness". In order to protect the information these people got, the USA secret service killed them all.

The "meat" of the book is the five chapters presented as the interviews with External Consciousness by these members of One Planet. If read as fiction, it is dry. Basically, it is External Consciousness explaining how a higher intelligence has designed the "biomatrix" - the biological system on Earth, the developments and so on. If read as science, well it is non science! The first interview is about the creation. Poised as a description of how Universe has evolved and how life on earth has evolved, the chapter is full of voodoo promoted by people such as Deepak Chopra.

I would not recommend reading this as fact or science. I would not recommend reading as novel too.

China tops U.S, Japan to become top patent filer

China as an emerging economy, her pace of progress is accelerating.

Economy develops, first by imitation. R&D is Repeat and Duplicate. Until one can do what others can do, there is no way to join the innovation bandwagon. Once one has mastered all the techniques, innovation can start.

After 30 years of importing technology, China is now poised to create her own. The story of high speed rail may shed a light of what is her strategy.

The Chinese high speed rail project started with co-operation with foreign high speed rail manufacturers in stages. At every stage, the foreign company was required to build the parts in China with an appointed factory. This same factory, after co-operation with 6 different foreign manufacturers, "digested" all the foreign technology and started to create her own intellectual properties. Now China is bidding to provide high speed rail to USA. While not the fastest, China has the largest high speed rail network. The only commercially operated Maglev is in Shanghai, China

Book Review: The Next Decade


It seems that Friedman is an author whom if you read one of his book, you have read all. In the review of The Next 100 Years: A Forecast for the 21st Century, I deposed that he has missed a number of key factors which will affect the next 100 years. In this book, I was expecting to read a proper analysis of the leading up to the current financial situation and what are the policy options for USA in the next decade. I am equally disappointed by his stubborn obsession of American domination as his book I last reviewed.

I disagree with his reasoning that the current financial situation in the America is part of a financial cycle. I agree with the view that it is the accumulation of no real wage growth while corporations reported soaring profits since 1980's. [ref] The middle class of USA has been collapsing. [ref] USA Government debt is about 100% GDP, almost as high as the one during the second world war [ref] The American's industrial base has almost completely off-shored to China. As I have noted in my last review, the intellectual capital of USA is also declining.

IMF predicts that China economy will overtake USA by 2016 which is within the scope of this book and Friedman just seemed unaware of this and continued to paddle that China will collapse due to internal conflict. [ref] Is that selective data gathering?

Politically, USA is corrupted. Bribery is legalized as lobbying. Friedman's notion that USA is an empire is ironically head-on. The government is working for a few privileged. The current style of western democracy has only been around for a few hundred years. When political leaders are elected based on popularity rather than demonstrated ability to govern and decision-making, one would wonder if the political system evangelized by USA is reaching its limits.

The next decade is an important decade for humanity. There are difficult decisions to be made, especially for the environment and climate - which is very much linked. Water, food, energy, climate, displacement of people are some of issues I was looking forward to.

Friedman did mention about water. He deposited that there are plenty, except not directly usable by human. The scarcity is fresh water and desalination is energy intensive and costly. Here are two possible projects USA government would have chosen to support. A few years ago, there was a project in Eritrea at which sea water was used to farm shrimps and fish. After that, the nutrient rich water is used to feed salt loving plants such as salicornia and then mangroves before returning to sea. Salicornia can by consumed by human, animals and/or converted into bio fuel. Unfortunately, the project was terminated by political reasons. If USA is to be a force for good, her political capital could have been used to save these projects. [ref] The other is seawater greenhouse as a possible solution for food and fresh water. [ref] While it is not too late to rescue the former project and provide support for the latter, if USA leaders, however, continue to think in line as described by Friedman, she could miss a golden opportunity and the world would be a little bit worse off.

Production of oil looks like have peaked in middle of the first decade of 21st century, a fact acknowledged by Friedman. If that is true, the price of oil will only go up. If USA economy can magically recovered in the next few years, the competition of oil from China and USA will drive the price to the roof, creating mayhem to a lot of people. Switching the transportation system to renewable energy source will need at least a decade. Switching baseline electricity load to renewable sources is also decades ahead. These infrastructures takes time to change. The geopolitical issue resulted from this is very dangerous if according to Freidman. Bumpy roads ahead, both for governments and people!

Food production is tightly linked to climate change. As the earth's average temperature is expected to continue to rise, extreme weather events will make food production unpredictable. Food price fluctuations would have significant political implications around the world - not only to USA.

If the consuming economy continues, one of the key resource in electronics and battery is rare earth elements. China has the largest reserve of them and produces almost 90% of all the rare earth elements in 2000. [ref] Again Friedman failed to see the importance of the control of these elements in a technological age and the implication to the USA economy.

When a country has been living out of her means for an extended time, when her political system is showing signs of weakness, when her economy is in trouble, when she is spending disproportionately in military rather than upgrading old and mal-functioning infrastructure, when intellectual capital is declining (comparatively), when health care cost is double that of the other nations' average without significant benefit, when a significant portion of the population is plagued by obesity, heart disease and/or diabetes, and a changing climate, declining energy source are in the near future, a world domination mentality would only led to a more dramatic decline. A policy based on military means to secure the scarce resources would only led to conflict. As there are many nations with nuclear capability, such a policy is very dangerous if not outright infeasible.

To be fair to Freidman, this book is about geopolitics and he was trying to look into a crystal ball. By missing several key factors, his future can only be wrong. He is also driving his predictions by a USA centric, dominating role overtune. For the sake of humanity, I hope there is no USA political leaders who will take his future as policy guides.

Book Review: The Next 100 Years: A Forecast for the 21st Century


With the advantage of writing this review 10% into the 21st century, I can point out the important factors that Friedman has missed in this book.

Friedman does not show an understanding of the Chinese culture which is rising rapidly and hence has misjudged the implication of a powerful China. He is absolutely correct that China was more like an isolated island, with difficult to penetrate borders on all sides. That is no longer true in light of modern technology. In 1421, before Columbus set sail to 'discover' the world, Chinese fleet, led by ZhengHe has already visited Middle East and Eastern Africa. The size of the ocean going junks used by ZhengHe built over 60 years earlier towered over Columbus ships. [see http://www.youtube.com/watch?v=FI1AmTa-bV0] Until about 500 years ago, China was the world's leading economy and power.

China has been conquered by foreign powers twice in her entire history. First at Yuan Dynasty which lasted less that 100 years and the second time at Qing Dynasty [1644-1911 CE] - the last dynasty before the new China was born. The result is that the conquerors were melted into the Chinese culture and became Chinese.

The above two snippets of history tell a story which Friedman has completely missed.

1. Being geographically isolated in the past, China has to be self-sufficient in order to survive. China could not depend on conquering other people to steal wealth. For an agricultural society to remain viable, a stable society was a prerequisite. As such, Chinese is a peace loving culture. When she has the power to conquer the world, she chose not to do so.
2. Being self sufficient, it was tempting for the Emperors to close the border and focused mainly on internal affairs. Of course the closing of trade in the last 500 years proved to be disastrous for China. Chinese, thus, has learnt a lesson which is still painfully remembered. A country needs a sufficient strong defense in order to protect herself. That's the main motivation why Mao insisted on China becoming a nuclear nation.

In Outliers: The Story of Success, Gladwell described a difference between rice culture and wheat culture. The southern China is a rice culture and that hard working moral has permeated throughout China. The discipline and efficiency of achievement as demonstrated by the 2008 Olympics, for instance, reflects the collective will of the Chinese people.

Can China continue to develop her economy? Friedman did not think so. I think that is his first mistake. Yes, dynasties came and gone. But China has remained as a unity. As Kissinger, correctly observed, China is more a culture than a nation state. It will not fragment as Friedman suggested.

Chinese economy started at a very low level. Until her per capital income is in par with leading economy, her economic growth is easy. She does not need to make mistakes which are typical at the "cutting edge". When Chinese per capital income is in par with USA, her economy would be 4 times larger than USA - just by size of the population. Recent global financial crisis indicates that USA economic strength is not at powerful as Friedman would have wished.

With a powerful peace loving nation in place, the world would be safer. Unless some leaders in a country are insane, waging war against a nuclear nation is MAD. There has been no world war since the invention of nuclear weapons speaks volume to the danger of major conflict. USA's navy power could not be used to force her will onto China, nor be used to limit Chinese economic grow.

Just by the size of the population, China is producing more PhDs in Science and engineering than USA. A report in 2002 predicts that by 2010, China will have more PhD graduating than USA. [source: http://english.peopledaily.com.cn/200210/21/eng20021021_105393.shtml] The consistent relatively poor performance of USA students in all educational measures points to a weakening intellectual capacity of USA. The best students in USA choose to study the soft easy subjects such as commerce and law. The best students in China choose to study the hard sciences. The intellectual strength of China will only increase while the same cannot be said to USA. The limiting factor to Chinese growth is resources and energy. The lower living standard in China means Chinese manufacturing can afford to pay more for the scarce resources than USA. In a world where military might could not be used to steal other nations' resources, China will compete on economic terms with USA for energy and resources.

China is the largest foreign creditor of the USA government. Chinese strategic dumping of USA Treasury bonds into the market can influence the interest rate at which USA government can borrow money. If there is any leverage a government can put on another, it would be China having an upper hand than the USA.

21st century will not be an easy century. The climate change will have significant impact on relationships between nations. Friedman has completely ignored this factor in this book. The world has already warmed by 0.8 deg C and there is a 1.6 deg C locked in even if by a miracle every country on this planet wake up tomorrow morning and take the most serious steps to fight climate change - which is not likely to happen. There will be large population displacement and serious "natural" disasters due to the effect of extreme climate. Economic resources will be stretched.

The declining of fossil fuel will also significantly affect the economic development. China has put renewable energy source as her main strategic goal and determined to be the leading manufacturer of renewable energy. Independence of fossil fuel has been a national agenda since President Carter. The domestic politics of USA has been delaying any action in reducing USA's dependence on oil. That's not a sign of a power nation.

From history point, USA is young, very young. In the wild, death at young age is not uncommon. Being young does not imply powerful.

If USA policy is informed by Friedman, she will be in very dangerous water. USA needs to learn from UK how to survive in a world dominated by power other than USA.

Book Review: Take Five!


I got a pre-release reviewer copy of Kaye Hagler's Take Five! from LibraryThing

First a couple of comments then I will describe the good points of the book.

1. The author started with

During my twenty plus years as a teacher in elementary, middle, and high school classrooms, I have tried almost every bell-ringer on the market. After all, the bell-ringer serves as a valuable classroom management tool for those crucial (and all-too-often chaotic) minutes at the beginning of the class period.

After I read the book, I still do not know what and how bell-ringer are supposed to be used in a classroom. I suppose that would be a technique common in USA classrooms. When I did a google search, I cannot find any information as well. If someone can explain that to me, I will be grateful.

2. There is a section called "A Little Learning Theory" in which the author listed a few educator such as John Dewey, Joanne Hendrick and focussed on their criticism of learning. However, this little section tells us nothing about the theories. I suppose readers would be familiar with these names - then what is the point of including such a section. However, for this book, this is OK because this book is not an education theory book. This is a teacher resource book!


So what is this book?

After I went through the first 10 pages, there are the meat of the book. An alphabetical list of 182 "prompts". Here is one example:

Paper or Plastics? 2
Plastic doesn’t seem to be going away, at least not today! How would life be different if plastic had never been invented? For example, there wouldn’t be AstroTurf for teams who play in covered stadiums or disposable silverware.

Without plastic, there would be more broken glass from bottles, meaning more cut fingers—and yet no Band-Aids to cover them. In fact, if you were to look around right now, you would see numerous items made of plastic: pencil sharpeners, pens, contact lenses, crates and shelving, clocks, table surfaces and chairs, computers, televisions . . . the list goes on and on.
Now it’s your turn. Brainstorm to list the many ways life would be different without the invention of plastic.

Use words, phrases, and clauses to clarify the relationships among claim(s) and reasons Develop the topic with relevant facts, definitions, concrete details, quotations, or other and examples

Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information, using strategies such as definition, Classification, comparison/contrast, and cause/effect; include formatting (e.g., headings), graphics (e.g., charts,tables), and multimedia when useful to aiding comprehension


*W.A.L.L. (Write A Language Link) is a folder on students' computers which the teacher can read and comment. Kind of like the wall in facebook.

If you are a language teacher, there are 182 ready-to-use templates which the author called "prompts" for immediate application or modification. "100-plus extensions lessons are also provided through the Teacher Tips."

It is good to see thinking skills being incorporated into any lesson. The fact that such skills can be learnt via fun and collaboration is the greatest strength of this book. However, the collaboration part, which is at the core of my own teaching, may improve slightly by adding a "debriefing" part to each and every activity. There is no mention of "debriefing" in the book (I did a search on "debrief" in the reviewer pdf of the book and found no reference to it). Debrief is the process of reinforcing the learning. When students can articulate what they have learnt - especially in thinking skills - in front of the peers, such a process also serves the purpose of spreading the thinking skills to other members of the class.

As a teacher resource for language teacher, I would give this book 4.5 stars out of 5.
