Teachers : Aaj Kal

by

Prof. V.K. Grover
Guest Blogger


A couple of days back, my son, Vipul asked me, how can we compare the present day teachers with those from the olden days. My instant response was that the old day teachers were better. It might be a reflex action to such a question as we are taught since our childhood that the old is gold. Nevertheless, the question started a chain of thoughts in my mind. Here, I'll be giving words to those thoughts as my son requested me to do the same.

When we talk of teachers, we need to consider all the teachers starting from the Professors in a big university to a school teacher in a village.

Let us first start with the University teachers because I myself belong to this fraternity. Moreover, if they are good, then they produce students of higher calibre, some of whom teach in the colleges and in turn produce good school teachers, who in turn send well equipped students for the higher learning, hence improving the country's human resources.

In the middle of the twentieth century when USSR launched its first satellite, Sputnik I; USA realized that it was lagging behind in the space technology. During this era of Space Race, USA opened its doors for the scientific intellectuals from all around the world, offering them handsome salaries and attractive working conditions. This gave an opportunity to many Indian academicians to visit USA and work with the best in the trade. Some of them came back with greater acceptability in the Indian society becoming members of an elite class of intellectuals. They took teaching and research assignments in Indian universities that gave boost to teaching and learning, particularly in sciences and mathematics.

Moreover, after Independence there was a major expansion in the higher education which led to quick promotional avenues for the teachers. This acted as a great work incentive as some of them even became heads of institutes at relatively young age. As those teachers were in the main stream of world research scenario, they were very successful as teachers and thus became role models for the future generations.

As the time passed, the expansion in higher education got stunted. There were lesser opportunities for promotions. Moreover, due to political reasons or otherwise, successive governments developed apathy towards teaching community. In order to make sure that the teachers are not marginalised in the society, the university and college teachers formed Unions and fought together to obtain better service conditions which they got in the form of establishment of UGC in 1970's.

However, they had to pay a heavy price for this in terms of loss of respect in the society associated with the noble profession of teaching. Monetary considerations took the priority over the academics and more and more teachers started indulging in private tuitions. In this scenario, the only formula to help the students obtain good marks is to give them some ready made tips and no efforts are made to make the basic concepts clear.

With the opening of I.T. enabled services sector, people are finding other professions more lucrative. Only the mediocre are now left to join the teaching profession. This decrease in the quality of University level teachers trickles down to the lower levels too.

This discussion will be incomplete if we don't talk about the school teachers who really lay the foundation for the future human resources.

In earlier days, in general, people were satisfied with the career they started with and were physically and mentally devoted to it. There are examples of teachers taking free of cost extra classes in the schools for the weak students and devoting extra time in sincerely checking home work of the students. However, as every one is becoming commercial these days, even they are not left untouched. Tuitions are becoming a fashion these days and there are innumerable cases of Government teachers forcing their students to take up private tuitions from them after the school.

In the olden times, the teachers also had a free hand in mending the pupils and even a bit of corporal punishment was a way of life. On the contrary, present day teachers have become more accountable. Parents are averse to any kind of corporal punishment and as such teachers have to work under many constraints; good or bad, is a different subject matter.

If we analyse further, we find that in the past, the access to information was not that good as it is today. Now with the invention of computers and Internet, the students are well informed while the students in the olden days had only one source for learning new things and that was the teacher. Hence he was looked at as the most learned person. However, today students can critically examine the teacher in view of the information available through the Internet and when the teacher is at fault, it automatically leads to decline in respect.

The introduction of the new technologies like LCD projectors and computers, however, also have there positives for the teaching community. A computer savvy teacher can plan his lectures well, make them more legible and give pictorial descriptions at ease, something which older generation teachers could not do. With the fast exchange of information through Internet and updating of technologies, if today's teacher is willing to put some effort, he can do wonders.

Beyond the old and present teachers, what about the future? The phrase old is gold will be repeated in future too. You may wonder that the quality of teachers might further decline. However, this is not the case. At any given time and in any profession, we have some good professionals and some black sheep while the most of the remaining are the mediocre. With the passage of time, we forget the black sheep and the mediocre and remember only the good ones, comparing them with the complete lot of the present professionals. This gives a bias against the present ones.

In future if someone happens to write about the teachers, he/she may come up with some other reasons but nevertheless the reasons quoted here are a food for thought. Some of the maladies plaguing the teaching community, mentioned here, if rectified or better removed can help in arresting any further decline in the standards.

A note from the Host Blogger:
Well, friends when this topic which had been suggested by me on the Blog-a-Tonic discussions, finally got selected, I already had some vague ideas about how to treat it. However, being totally held up due to studies, I thought why not pass the buck onto the person who has more than half a century of association with the education sector, first as a student and then as a teacher himself. Being a Mathematician, my father has always played with numbers. So here, I challenged him to play with the alphabets. He was hesitant at first but finally yielded and came out with a brilliant analysis. What you read here is the final version with minor editions from my side.

The Monsoon राग ।

Followed by some food for thought
A Rainy Day - Drawn by 'a 6 to 8 years old' me

With the maximum temperatures hovering above 40°C (104°F), Chandigarh has been eagerly awaiting the advent of the monsoon. The showers we got on the 16th of June were, as later revealed by Meteorological Department, due to western disturbances and not pre-monsoon showers as I mentioned in a post that day.
The monsoons have always been a child's paradise. I fondly remember bathing in my balcony under the natural shower and those paper boats which my father used to make for me so that I could float them in the puddles on the road.
Doesn't that remind you of the first verse of a particular song, immortalized by Jagjit Singh's unique baritone:

यह दौलत भी ले लो, यह शोहरत भी ले लो;
भले छीन लो मुझसे मेरी जवानी
मगर मुझको लौटादो बचपन का सावन;
वो कागज़ की कश्ती, वो बारिश का पानी

Tune in to listen to the complete song




Here's an amusing but apt translation from my side (try singing it to the original tune;)

Take this money and take this fame;

Even snatch my youth if you may.
But give me back my childhood's monsoon;
That boat made of paper, that water of rain.

Before you accuse me of filling my post with someone else's creation, I'll reproduce two poems, I wrote long ago. Yup, the two are from the same childhood collection from which I have posted last time and earlier too.
I remember writing the first one for a home assignment. I was finding it pretty difficult but suddenly it started raining. I went out in the balcony and started writing. The words just flowed naturally after that.

The sun was invisible and the clouds turned black
At that time I sensed, that monsoon has commenced
The drops of rain trickled down, making the sight beautiful
Happy were the people of town, before who were mournful
Peacocks started dancing and the frogs crocked with happiness
God blessed the burning Earth as for her it was a new birth
Monsoon is the King of seasons, to say this I have many reasons
Rain is the love of God, in disguise of the water drops

After this cute little poem, here is another one, but this time in Hindi. Well, there is no anecdote related to it.

सोंधी सोंधी खुशबू आई, मन में एक तरंग जगाई
टप-टप-टप बरसा पानी, यह है प्यारी वर्षा रानी
सब के मन को स्वछन्द यह करती, ठंडी करती तपती धरती
तरस विधि को धरती पर आया, देवराज द्वारा पानी बरसाया
तालाब पर यह छम-छम करती, सबके मन में खुशी है भरती
किसान नाचें, पक्षी चेह्चहाएं, मोर नाच मोरनी को बुलाएं
खेत फिरसे हैं लहलहाते, हरे-भरे पोधें हैं भाते
बच्चे कागज़ की कश्तियाँ बनाते, फिर उन्हें पानी में बहाते।।
वर्षा बड़ी सुहावनी है लगती, कोई ऋतू ऐसी नहीं होती

The two poems are so similar in the spirit as well as structure that both can be regarded as each others translation.
In these two poems my affection towards monsoons has been expressed quite succinctly with the childhood's innocence. With time, I believe this affection goes down as rains become more of a nuisance for us. Afterall, who likes to get drenched while going to the college on a bike or get late for an exam or maybe, a date.
The biggest evil of rain for an average Indian, young or old, is when a much awaited cricket match gets abandoned due to it or India is defeated thanks to the bogus Duckworth-Lewis formula (though when the result is in our favour the same formula becomes the lifesaver).

On a serious note:
Well, we might change, our priorities might change and hence, our love for monsoons might change but let us hope that monsoon never changes. Sadly, it has changed its trend over the years and is becoming more and more unpredictable.
The havoc created by monsoons in Mumbai in recent years is fresh in our memories. On the other hand, this year, it has arrived much later than what was projected by MET Department and it is expected to be stunted in duration and rainfall.
This year's late arrival has been largely attributed to El Nino; a global periodic ocean-atmospheric phenomena that arises in tropical Pacific due to over-heating of the ocean waters and leads to the weakening of high pressure over the Indian Ocean which in turn weakens the South-West Trade Winds that bring monsoons to the low pressure belt of Indian Subcontinent in summers.
However the role of Global Warming, though not authenticated as yet, in bringing about a change in the general trend of monsoons in the recent years, can not be ignored.
The late and stunted monsoons directly impact the Indian economy negatively, at the macro level. Moreover, at the micro level, it negatively affects the livelihoods of thousands of farmers, dependent agricultural labourers and those associated with the agro-based industries and the auxiliary services throughout the country.
Such a scenario makes it all more reasonable to fight Global Warming with much more vigour and zeal.

In the shadow of Global Warming

How can India survive this meltdown?

In my zeal to increase my blogging output, I have been writing on various aspects. However, somewhere in this race for quantity, I felt as if my blog was losing its quality and its essence, i.e., empathic libertarianism. So I thought of exploring it once again.
Climate change and global warming, it seems are the ‘in’ words. No discussion seems to end these days without a faint reference being made to them. Here, I am not going to elaborate on these discussions of the intelligentsia or the masses but will succinctly show, where India stands in all this and explore the options it have.
Global warming is a common problem for the humanity (and sadly, of the humanity and by the humanity too). Who-so-ever might be responsible for it, it has to be tackled by everyone in unison. Take the example of the global economic meltdown. It originated in USA but engulfed all the world economies disproving amongst others, the decoupling theory. We all are facing the repercussions and we all have to act together. Ironically, in the middle of this economic crisis, the harbinger of the problem unleashed a protectionist regime; unlearning the Smithsonian legacy, it so avidly advocated to others, all these decades.
Coming back to global warming, India’s stand on its mitigation has been quite myopic. It has been using its low ‘per capita carbon emission’ figures as a justification to continue with the high growth rate of carbon emissions (three times the world average, as per an estimate).
Statistically, it’s true that our total emissions per person are way below the industrialised nations'. But the simple question here is can we afford to take such a micro view. After all, who will be more adversely affected by the climate change, the countries with high population density or those with low?
When the coastal areas (like our cities of Mumbai and Chennai) get submerged and people move inwards, the pressure will be felt most by the countries like India. USA with a size, 3 times larger than ours and population, 3.5 times lower, can easily afford moving the people inwards. But can we?
Here, I put it in very simple terms taking just one example. However, to elaborate, I'll add that whatever be the negative consequences of global warming; unbridled climate change, receding glaciers, drying up of perennial rivers, drop in agricultural output, complementary floods and famines or the submergence of land as already mentioned; it will be felt the hardest by a country like India which supports a sixth of the world's population on just 2.3% of the total land mass.
Sadly, it has been authenticated that the Himalayan glaciers are fast receding and the islands of Gangetic delta in West Bengal are already loosing their land mass. Even if the recent flood havoc by the Kosi river in Bihar is a distant example for many of us, it can not be denied that the summer this year is getting a bit too hot than the previous years. Hence, our policymakers need to take a much wider view of the situation.
However, with this argument, I don’t intend to absolve the developed world from all the sins they have committed all these years. As per an estimate, today the rich nations of the world, with just 20% of world population, already occupy three quarters of atmospheric space. These nations have to take the responsibility and provide the developing world with technologies and resources to tackle their emissions.
Clean Development mechanism (CDM) under the Kyoto Protocol wherein industrialised countries can invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries, is such an arrangement. However, it tends to give such rich nations a license to continue emitting unabated. Hence, further safeguards are needed within the CDM too.
On India’s part, no time should be lost in developing better mechanisms for controlling climate change and the country should vociferously ask the richer nations for financial and technological aid for itself and fellow developing nations.
Search for better alternatives to carbon-emitting fuels should be taken up seriously by both government and the civil society at large. At the same time, efforts must be made to attenuate the various carbon sources and develop appropriate carbon sinks. For example, better public transport, if made available to the people, will automatically act as a deterrent to private vehicular traffic and the associated pollution and carbon emission. Along with it, demarcating 'green zones' in the city precincts or growing trees along the roads will help in reducing the impact of pollution.
There have been some welcome moves in this direction in recent period.
  • In June 2008, the foundation was laid for a 2-MW solar power plant at Asansol in West Bengal and this marked the inauguration of work on the first grid connected solar power plant in India. Other states like Haryana, Tamil Nadu and Rajasthan are also taking steps in this direction.
  • India's first tidal power project is slated to come up in Durgaduani creek in the Sundarbans in West Bengal with 90% of the funds being sanctioned by the Central government. The project is expected to be completed by the end of 2010 and will help in developing further capabilities in the Gangetic delta of Sunderbans as well as Gulf of Khambat and Gulf of Kutch in Gujarat.
  • Delhi Metro Rail Corporation became the first railway project in the world to be registered by the United Nations under CDM which will make it possible for the corporation to claim carbon credits.
  • Project Green was launched as a joint initiative of the Energy and Resources Institute (TERI of Rajendra Pachauri fame) and Bharat Petroleum wherein farmers are being provided elite planting material, technical help and training. They are also being organised into groups for local decentralised expelling of oil. This oil is proposed to be used both locally and for the production of biodiesel.
The list presented above is based on some articles which I came across in newspapers and documented for further reference for my examinations. It is not exhaustive but only indicative of the proactiveness shown in India in last one year or so.
One has to hope, more such initiatives are taken up not only to develop alternative sources of energy but also develop a common understanding of the problem and a strong commitment to its mitigation among the government officials, private sector and above all the people at large.
Update (June 24, 2009)
Nearly a year ago, on June 30, 2008; Prime Minister Manmohan Singh released India's first National Action Plan on Climate Change (NAPCC) outlining existing and future policies and programmes addressing climate mitigation and adaptation.
The plan identifies eight core 'national missions' running through 2017. These missions cover the areas like solar energy, improvement in water use, enhancing the energy efficiency, ensuring sustainable habitat, conserving Himalayan ecosystem, afforestation, sustainable agriculture and developing strategic knowledge for Climate Change.
The existing programmes enumerated include those dealing with power generation, renewable energy and energy efficiency.
It is yet to be seen if these initiatives just remain on the paper or are religiously implemented by the concerned ministries.

Power swings 2008

Politics, economics and Cricket

As the year 2008 comes to a close, it is interesting to look back at some of the developments that challenged the existing order and made one ponder if these are indications to an eventful 2009.
The U.S.-Russia tussle saw two major geographical manipulations in the Russian vicinity. The first was triggered by U.S. support for declaration of independence by the Serbian province of Kosovo in February, the latest thread in the Balkanisation process. However, the month of August gave Russians a chance to return the favor, thanks to Georgian belligerence in its northern province of South Ossetia. Russians routed the Georgian army and recognized South Ossetia's right to secede along with another Georgian province of Abkhazia. U.S. might have triggered this event too but the Russians had the last laugh while U.S. was left fuming at the sight of its beleaguered ally.
There was more to come at the strategic level. U.S. in its move to bring the NATO forces and artillery closer to the Russian borders; supported the inclusion of Georgia and Ukraine in the cross-Atlantic body, and made known its intentions of installing air defense systems in Poland and Czech Republic, under the garb of Iranian threat. As the year came to an end, Russian fleet too set its sails towards the American seas to hold joint war games with Venezuela. Moreover, Russia too plans to strengthen its defenses (and offenses) in Kaliningrad Oblast bordering U.S. allies, Poland and Lithuania.
On the energy front too, Russia has successfully brought together the Gas exporting countries under an OPEC-like institutional framework which has further added to its clout, much to the dismay of U.S. It will be interesting to see what course this age-old rivalry takes in the coming year.
While the above developments hurt U.S.A.'s international standing badly, its homegrown sub prime and mortgage crisis triggered such events that now threaten its economic hegemony too. World saw the Gulf sovereign funds coming to the rescue of American banks, an unprecedented development indeed. Though the decoupling theory proved wrong, but still India and China seemed better prepared for the crisis than ever before. A couple of weeks back, China, Japan and South Korea summit saw new economic partnerships being forged to work out a coordinated strategy against the global financial meltdown, an indication of countries looking beyond U.S.
Earlier in July this year, Doha rounds, the free-trade negotiations of W.T.O. collapsed in Geneva, as the developing countries led by India and China refused to yield to U.S. terms and conditions. Moreover, the recent revelation of Maddoff Ponzi scheme brought further disrepute to the Wall Street and the U.S. nation as a whole.
Away from all this politics and economics, another superpower is being threatened and the year 2008 has been very tough for it. Australian Cricket can never be the same again. They started the year defeating India in the controversial Sydney Test thanks to the magical over bowled by Michael Clark. However that was the end for them and a beginning for the bruised Indian team. India won the next test and though lost the test series, came back with vengeance in the One-dayers. In the three final matches tri-series, India under Dhoni never needed the third final.
There was more to come in October-November when Australians came to India for the next edition of Border-Gavaskar Trophy. They did come with the trophy but could not take it back, being defeated 2-nil by the resurgent Indians. In between India tied a test series with South Africa at home and lost to Sri Lanka at their home but returned the favour in the one-dayers.
Indians brought the year to an end with an inspiring test victory at home against England. In the first test, the Sehwag blitzkrieg left the Englishmen clueless and the cricket lovers bedazzled. However the year ending has proved dismal for the Aussies. Proteas' heroics in the first test at Perth saw South Africa scaling a target of 414 with great agility and confidence. With the Boxing Day Test, the final and the most crucial test match of the year having started just half an hour back (and Hayden continuing with his poor form, already back to the pavilion), one wonders how the Kangaroos will fair this time. Australia might have amassed a lot of points on the test ranking table, thanks to the likes of McGrath, Warne and company but with these stalwarts retiring from the international scene, the going is getting tougher for the Ponting men or rather boys. India and even more strongly, South Africa have started fancying their chances to bring an end to the Australian hegemony in cricket.
In the corporate sphere of cricket, BCCI continues to extend its hegemony. With the successful conduct of PCL, Lalit Modi has become one of the most powerful sports executive in the world. Hence, the year 2009 holds a lot of promises for India in the cricketing arena. One hopes the good performances of 2008, seen in the other sports like shooting and boxing continue the next year too, to give a better platform for the Indian contingent at Commonwealth Games to be held in the National Capital in 2010.
Coming back to politics, U.S. saw a major domestic power swing as Democrats under Obama came back to power. Republicans had their eight years under Bush and they ended up doing all that should not have been done. Bush revealing earlier this month that his biggest regret was the U.S. intelligence failure on Iraq sums it up.
However, back home, power politics kept swinging all through the year. NDA's Karnataka victory earlier this year, saw them gaining a lot of mileage for the coming general elections but the results of recent assembly elections in Chhatisgarh, Madhya Pradesh, Rajasthan and Delhi humbled the saffron brigade to some extent and filled a new zeal and confidence in the Grand Old Party of India, which was fearing for worse.
"We have taken a risk", is what Chief Election Commissioner had to say on announcing the schedule for elections to the Jammu and Kashmir State Assembly, back in October. Earlier in the year, the way events had unfolded around the Amarnath shrine board issue, it seemed the separatists will have a field day if and when elections are conducted. Air in the Valley seemed rife with secessionist emotions and no one predicted that democracy could have the last laugh.
However, with all the seven phases of election over in the state, one is amazed at the voter turnout figures, much above than the previous occasions. Hence, the year ending saw the power swinging back in the favour of the democratic process in the northern-most state of India. In another couple of days, we will come to know, who will wear the crown and hopefully, strengthen this process further in 2009.
On the corporate front, Indian companies continued their foreign acquisitions, though at a lesser pace than in 2007, led by Tata's takeover of Land Rover and Jaguar brands from Ford. However, the Japanese firm's takeover of Indian pharmaceutical giant Ranbaxy spoilt the party to some extent.
India's successful moon mission, Chandrayaan was another step in the Indian as well as Asian elevation in space technology. With Indian-built European satellite W2M being launched last Sunday from French Guiana, it adds further to ISRO's clout and coffers.
Further on technology and more importantly strategic front, India signed the Nuclear Cooperation Deal with U.S.A. , Russia and France after getting unprecedented go-ahead from NSG and IAEA. By successfully carving out a special place for itself in nuclear arena, India has successfully de-hyphenated itself from Pakistan.
Recent developments post-Mumbai terror attacks are seeing Pakistan being further marginalized. Even its strong ally China has not come out with open support as on previous occasions. Year 2009 is going to be very crucial for India-Pakistan relations and may see major power swings in South Asia with U.S. committed to escalate its war against terror in Afghanistan under Obama.
