Mid-semester musings 

From chasing away monkeys to preparing a comprehensive yet accessible Spider Graph, Preeti Aghalayam writes on the multiple hats a professor at IIT-M wears — whether by choice or chance

It’s 7.50am. Cars outside IIT-M’s main gate stretch back all the way up to Madhya Kailash. Horns blare their impatience, and the frustration of a Monday morning commute hangs heavy. As I enter the campus, a sense of calm descends almost immediately. The tree-lined avenues ahead are welcoming, cocooning even. A couple of kilometres of driving and a song on my lips, puts me smack-bang in the academic zone.

With earphones plugged in, a motley group of students walk; some pedal their way on cycles, unmindful of the traffic. There is an unwritten rule on the campus: deer and monkeys; pedestrians and cyclists; and professors and staff are given decreasing order of importance. I slow down, catch my breath and inch forward, trying to avoid a particularly belligerent cyclist who swerves in front of me. I have finally made it! Just a minute or two before 8am.

As I walk up to the Classroom Complex (CRC) building, I notice the massive banyan tree, whose arms have spread everywhere. How old must this beautiful piece of Nature be, I wonder, as I power walk my way through a chatty bunch of students to the classroom. This term we are in a new place, a fully-equipped hybrid teaching-learning studio, thanks to NPTEL (National Platform for Technology Enabled Learning), a massive online learning initiative by the IITs and IISc. 

The studio — with its plush-green seats, bright maroon curtains, and a full-fledged audio-video set-up — is colourful and has the right vibe for a modern classroom. Pretty soon, I’m letting the students in — on a giant screen. Yes, this is a hybrid classroom with 20-plus students on campus with us, sitting in those plush-green seats, and a handful logging in remotely from Kathmandu, Nepal. 

“There are monkeys in the stairwell,” says Bikram*, his eyebrows raised in wonder and a bit of fear, perhaps. I notice several students behind him; they all laugh in one voice. Meanwhile, I pick up a handy stick hiding amidst the AV equipment and go chase the monkeys away, and escort the rest of the class in. The things we end up doing as professors, I tell you!

Scenes from a classroom 

“Well, let us start the class at least as per Indian Standard Time,” I joke. Time and again, we have grown used to all the excuses students come up with when they are late to class. It is not like we have it easy either: traffic was maddening, parking was hard to find, I had no time for breakfast, and then the dappled sunshine through the trees looked so particularly beautiful today I ended up admiring the view for a bit…the list goes on. But yes, eight in the morning is objectively early at any rate. I will give them that. 

The class starts with a poll; there are titters as I explain how to access the poll. I stop mid-sentence realising that those born in the smartphone generation don’t necessarily need an explanation on QR codes. “The most important research skill is the ability to observe your surroundings,” I tell them. But before I can finish, they have finished with the poll — and the responses are a good mix of reflection and humour. It makes my heart warm with hope. 

Today’s class is about making plots and graphs to visualise scientific data. I show them some of the “bad examples”; and ask them to be critical. The students have at least 10 things to complain about: some are important, and some are nit-picky. I walk around the classroom, before asking them to sketch an improved version. 

Meanwhile, Dipti* unmutes her mic and calls for my attention. She holds up her version of the (improved) graph in front of the camera. We all love it. The class continues with a few more examples — the Spider Graph, which many students had not seen before, is a hit. 

We have our many arguments and, as one would expect from a class with such diversity — female students constitute 20%, while 40% are from Africa, two students are from Bangladesh, and of course we have a group joining from Nepal — the discussion is rich. When you are in such a vibrant classroom, time progresses swiftly. We were all exhausted at the end of the hour, though I enjoyed every minute with them. And if the smiles of the students as they troop out are anything to go by, so have they. 

As I walk out of the classroom, I emerge into Chennai’s sunshine and make my way over to the canteen for a cup of strong South Indian filter coffee. My mind buzzes with the thought of data, graphs and Slido polls. I check my watch, it’s only 9am.
