AICTE to introduce students feedback-based assessment for the promotion of Engineering teachers

Besides research work and their overall performance, teachers in Engineering colleges will now be appraised on the basis of students' evaluation All India Council of Technical Education's (AICTE) decision to include the students' feedback to assess the teachers has been introduced to improve the educational quality of engineering colleges. But, its effectiveness remains to be seen. "Since students' feedback will be considered while granting promotion to the teachers, they will have to put their best foot forward in the classroom. This assessment pattern is followed by the IITs and NITs," says AICTE chairman Anil Sahasrabudhe.

As per the rule, students' feedback will have 25% weightage in the overall assessment of the faculty, which will be a decisive component for their promotions. Till now, the focus for promoting teachers in colleges has been on the number of research papers published by the faculty members. This was partly the reason for the publication of substandard research papers in fake journals. "Colleges in tier II and III cities, may not have the resources to conduct research. But research publications being given high priority during promotions often leads to the problem of paid journals. The new assessment will thus award good teachers," adds Sahasrabudhe. While some academicians are positive about the impact of this assessment system, others are of the view that students might not be honest with their feedbacks owing to various reasons. "Students are sometimes not objective or may be simply confused while giving feedback for teachers. Their opinions are based on peer thinking. While interacting with the students, I have come across several students who behave differently in class and during one-on-one interactions," says Govinda K, professor, School of Computer Science and Engineering, Vellore Institute of Technology (VIT). Addressing the concern, Sahasrabudhe says that the number of such students is mostly low, thus the overall score of a teacher who is good at his work is not hampered. "Some students may give poor feedback, probably because the teacher is strict or is not lenient with marks, but this is temporary. In the long run, a teacher who is passionate about teaching and thinks about students' welfare will always be valued by the majority. Also, such an assessment will also ensure better student-teacher communication," he says. This system will allow the teachers to address their weaknesses and improve teaching methods, says KK Mahapatra, dean, Academics at NIT, Rourkela. "Since students are the direct beneficiaries, this will help the teachers to analyse their skills, for instance, maybe there is an issue with communication or students might be finding the teaching method complicated," says Mahapatra.

Niranjan Karagi’s Nirnal world’s cheapest portable water filter

Sometimes, the inspiration for the most brilliant of inventions can come from the most humbling of places. Such is the case for NirNal founder Niranjan Karagi while he was playing in a schoolyard nearby his home has invented and patented the world’s cheapest water filter which costs Rs.30 and can be used for 100 times and fits any water bottle and this removes 99% of bacteria and other disease-causing water contaminants.

AAB is proud that we were the first ones to cover his project in December 2016, An Engineer Filters the Way to Success.
Niranjan now has many accolades to his name including Best Entrepreneur Award by Deshpande Foundation – Feb 2017, Best Entrepreneur Award by Visvesvaraya Technological University (VTU) – Jan 2017, Yuva Shilpi Award by Akhil Bharatiya Vidyarthi Parishad (ABVP).
It is a compatible, portable, reusable, healthy and an eco-friendly water purifier. A product that ensures ‘Safe Drinking water ’ at an affordable price. This acts as a filter when the water oozes out of Nirnal fixed to the bottles. It is easy to use, imparts taste and also adds some essential minerals to the water. It uses activated charcoal, Filter cloth.

Niranjan did his schooling from St. Mary’s school Belagavi and PUC from Govindram Seksaria Science College, Belagavi. Later completed Mechanical engineering from Angadi Institute of Technology and Management in Belagavi.
During his free time, he noticed some small children using the playground and filling up their plastic water bottles from a potentially unsafe tap. Bearing witness to the scene, Niranjan reflected sadly on this reality and felt that all children should have clean water despite their income or area of residence. It was certainly not a surprise for the young leader to think of such social issues, given his involvement in the LEAD program at AITM College Belagavi. But it was this particular case that leads him to create something that would make a significant social impact for many people.
Water filtration became the main theme for Niranjan as he began to brainstorm ideas on providing a clean, low-cost source of water. Seeing as his research revealed the relatively high prices charged by competitors for filters, the future entrepreneur settled on creating a water filter that was both very affordable and portable for bottles. His first prototype used materials that were easily accessible around the house but after some assistance from LEAD, a second prototype was created that took Niranjan 4 painstaking months to perfect. The result was a small filter that could be fitted into any standard plastic bottle with an incredibly low cost of 20 rupees.
At that point, all the hard work put into the prototype paid off. Approval was given by the Food Divisional Officer stating that the filter could purify up to 100 liters of water. Furthermore, Niranjan turned to social entrepreneurship as a means of spreading his technology by agreeing to receive tier-ii incubation support in Belagavi by the Sandbox-IMER center. Sandbox Startups was instrumental to the founding of the NirNal enterprise, officially registered with the Ministry of Micro Small and Medium Enterprises in Belagavi. Furthermore, the incubation center gave him a platform to pursue his ideas for his product while gaining business knowledge about scalability and validity for the purposes of society. Complete with networking events, partnership opportunities, mentoring, and investor meetings, Sandbox Startups was an essential springboard to Niranjan’s growth as a social entrepreneur.
The social impact of his product has been significant. With the distribution of his product to various villages, schools, and even India’s military, it is evident that NirNal has been widely acclaimed for its ingenious and inexpensive technology. But on a personal level, Niranjan is happy with the fact that children could use his filter, knowing that they would always have a reliable source of water as they grow up. Niranjan’s initial wish to provide clean water to everyone has become more and more of a reality through the means of his portable water filter. This reality was made possible for thousands of people as 12,000 units of his filter have already been sold.
Indeed, it is exciting to see how NirNal will scale with its water filters. Niranjan himself has stated that he would like to improve the unit even further while maintaining a low price, all while maintaining his goal of providing clean water to all rural people. If he were to truly succeed in his endeavors, there would be much cause for celebration for this ingenious invention.

MU reschedules 76 examinations

REGULAR FINAL EXAMINATIONS OF MOST SELF-FINANCED COURSES WILL NOW BEGIN ON MAY 2
MUMBAI: The University of Mumbai (MU) has rescheduled 76 semester examinations, including final BCom tests and most self-financed commerce courses, and few papers of 27 examinations, to avoid a clash with next month’s Lok Sabha elections.
The 76 examinations, which include sixth-semester exams of BMS, BCom (Accounting and Finance) and BCom (Banking and Insurance), have been entirely pushed ahead by a few days.
Some papers of the other 27 examinations, including sixth-semester BCom examinations, will be held on different dates, which are yet to be announced.
“The university has tried to make minimal changes,” said Vinod Patil, director, examination and evaluation board.
The four phases of general elections on April 11, 18 and 23 and 29 are set to overlap with MU’s examination schedule.
With the colleges doubling up as the examination and polling centres, and teachers assigned various election duties, the university has decided to move all the major papers being held on the polling days as well as the days preceding and following them.
The regular final examinations of most of the self-financed courses, which were to start on April 22, will now begin on May 2.
“The university should have ensured that all the examinations end on April 30 — the last day of the term. The teachers will now have to be requested to work during summer vacations. The academic calendar won’t be affected if the date of commencement of the next term is not extended beyond June 11,” said Asgar Lakdawala, principal, Royal College, Bhayander.
However, Gopal Kalkolti, principal, MV Mandali’s College, Andheri, said, “The revised schedule may delay results and admissions to post-graduation courses to some extent.”

Move IST ahead by 30 mins, save 3.5 billion units of energy: Scientists

Two time zones will create a divide between the eastern parts of India and the rest of the country. Our proposal for advancing the clock will not force people to change their schedules or habits. DP SENGUPTA, Retd professor, Indian Institute of Science

MUMBAI: The country can save 3.5 billion units of electricity every year if the Indian Standard Time (IST) is advanced by 30 minutes, two senior Indian scientists who first proposed the idea of a timezone shift a decade ago said on Monday.
At present, India is five-andhalf hours ahead of the Greenwich Mean Time (GMT), and among few nations with a fractional shift — in minutes — from GMT. Most countries add or subtract hours from GMT to create their standard time zones.
In 1884, India had two time zones – Bombay time and Calcutta time. On January 1, 1906, British India adopted IST of fiveand-half hours ahead of GMT. Only the Assam tea gardens operate one hour ahead of IST (chai bagan time).
Retired professors DP Sengupta from the Indian Institute of Science and Dilip Ahuja from the National Institute of Advanced Studies (both based in Bengaluru) in a 2009 study funded by the Bureau of Energy Efficiency had recommended advancing the IST by 30 minutes to obtain energy and non-energy gains. They estimated India would save an estimated 2.1 billion units of electricity every year or 0.3% of the annual consumption of 750 billion units.
For 2019, the duo has said if IST is made six hours ahead of GMT, India can save 3.5 billion units from the annual 1,200 billion units of electricity consumed. According to their study, there will be a saving of 17-18% during peak energy time, such as during evenings when there is a lot of power demand.
“India is investing heavily in rural electrification, and therefore energy demands will also increase in the future. With most of the electricity requirements met by thermal power plants, a one-time advancement of 30 minutes will save us from burning coal to produce 3.5 billion units every year,” said Sengupta during a talk at the Observer Research Foundation.
The scientists are opposed to the idea of implementing daylight savings twice a year as is followed in Western countries or two time zones for India as recently recommended by the National Physical Laboratory. “Two time zones will create a divide between the eastern parts of India and the rest of the country, and lead to confusion in travel schedules. Our proposal for advancing the clock will not force people to change their schedules or habits,” said Ahuja.
Five Asian countries that have implemented one-time advancement in their clocks are China, Kyrgyzstan, Malaysia, Singapore and South Korea.
Despite making several presentations to various government departments and bodies between 2010 and 2014 and getting letters of endorsement on their proposal, nothing has happened.
“Governments and policymakers have shrugged their shoulders and moved on. We need individual states on board as stakeholders,” said Sengupta.
