Teach how to think and not what to think

With the changing times and across levels of education, one thing that might have remained constant is that good teachers always teach how to think instead of being just the source of information on what to think. They use all the resources around them to help student's build their personalities. The goal of education cannot be mere preparation for earning livelihood in future. Coaching and training are enough for that purpose and anyone with proper access to the information can gain enough knowledge to earn a living. Better society is not formed by better earning future generation alone, it is formed by better ideas, innovation and evolution of human values, generation after generation. 

Given the technological advances and access to enormous information, students of 21st century are not dependent on formal coaching for making ends meet. Before a teacher starts teaching a topic in classroom, some of the students may already have number of different pieces of information on the topic which may very well be differing from the textbook version of the facts, not any particular of them being necessarily the correct one. This makes the role of teachers in the process of education of 21st century even more critical and challenging.
In the vast sea of information, teachers first need to learn fast on their own, be updated on the various perspectives on the same topic, learn from the students, and above all of this, they need to be the guides who will ensure that the learners are going in the right direction while surfing through all the information. While technology brings lot of resources for teachers, it also makes their role even more challenging. The more reluctant teachers are to adapting this change, the more directionless will be the future generations.
So should the teachers gain a lot of knowledge? Should they really know which direction is correct for each of the students? That would fairly impractical and inefficient. So while being updated on the teaching resources, the teachers need to be able to guide and mentor their students on certain basic values which will help them filter the information for its rationality, correctness, interest, ethics and practicality. There would be more such basic values and each teacher needs to develop them on their own. But once the students get the sufficient 'coaching' on these while learning the set courses, there is more likelihood that they would neither be lost in the amount of content, nor be restricted in their perspectives. This would further help them be more self-driven, innovative and practical. Once these values are imbibed, they would be sufficiently equipped to both sustaining a livelihood as well as making a better society of their own.
Teachers need not just remain the source of information, either from textbooks or from internet, either on paper or on the screen, they just need to provide proper pointers on what to look out for, how to filter that, and further encourage its practical use by means of 'creating' various kinds of useful resources from that. For doing all these, they can very well make use of the technology solutions, which facilitate creationism, collaboration, prototyping, and automation for the mundane tasks.

PVR is so wierd!

Yesterday we went second time to a mall bit far from office to complete the earlier failed mission of watching this 3D movie, Clash of the Titans. On ticket counter, we were first told that evening show was house full. Then we asked for a night show, and were told there isn't any show then and the gentleman handed us the pamphlet of all movie schedules. We checked on the nearby digital kiosk and also on the printed schedule to be sure of the show timings. Then went to second counter, and asked the lady for the night show tickets, and without any problem got the tickets for back seats. In fact this show was hardly 20% full, wonder how the evening show became houseful.

But the biggest wonder/blunder is yet to come. On the entrance we were stopped for having a laptop bag along with (we had went straight after the office). In spite of having checked the bag, we were not allowed, because laptops were not allowed inside! Then we asked for keeping it at the baggage counter. But then, the…

अग्निपथ से धूलपथ तक!

अक्सर दिल्ली की धूप में 'दोपहर' के १० बजे घरसे निकलो, तो अपनी ही दशा को देखकर सबसे बड़े बच्चनजी की पंक्तियाँ याद आती हैं।

यह महान दृश्य है, चल रहा मनुष्य है,
अश्रु-स्वेद-रक्त से लथपथ लथपथ लथपथ।
अग्निपथ अग्निपथ अग्निपथ...

किंतु आज तापमान में गिरावट और धूल-वायू की लहरों के चलते, दिल्ली की सड़कों को अग्निपथ से 'धूलपथ' में परिवर्तित होते पाया गया है। फिरभी देखा जाए, तो इसे उष्मा से मुक्ती का एक तात्कालिक ही सही लेकिन सुखद अनुभव कहा जा सकता है।

Designing for scalability – a startup perspective

What is scale? Is it the number of customers a company has? Is it the number of products that are sold? Is it the amount of revenue the company makes? Is it the amount of infrastructure one has? Or is it the number of features the product has? Well, it can be all of this or none of this. When an organization talks about scale it is not just a number. When an economist talks about it, again it’s not just a number. For an economist, the scale is about doing more with less. Scale is about perspective, about relationship between two or more variables that ultimately help you generate optimum value for your efforts.
Consider this, let’s say you are into making a lollipop. Selling 10 lollipops you earn $100 revenue of which $10 is you profit and $90 is the cost. When you increase you production you start selling 100 lollypops and earn $1000 revenue with $100 as your profit and $900 as cost. Did you really benefit from the scale here? In absolute terms, of course. In terms of ratios though,…
