1/ I've now taught my "Defense Against the Dark Arts" course (teaching teenagers about misinformation, fake news, misleading ads, etc) to 4 batches, and it has been a very rewarding experience for me
A quick thread on my learnings and suggestions for you
2/ My biggest learning has been how quickly children figure out things with the help of the internet as long as they are just pointed in the correct direction.
They don't need teachers. They need people who can motivate them and point them in the right direction.
3/ Consider the exercise in this photo. I gave them no other coaching, but within minutes most of them had figured out why each of these ads was misleading and they were able to articulate and discuss subtleties like "The product is a good product, but the claim is exaggerated."
4/ Suggestion for parents/teachers: Instead of trying to teach students, just seed their mind with intriguing questions and let them find answers on their own. There's educational research suggesting that this actually works quite well, even for very complex problems
5/ Another surprise for me was that students wanted more. "There should have been more homework" is quite a common complaint in the feedback forms. As are requests for more reading material.
For the right material, and the right environment, there is a hunger to learn.
6/ Sadly, the bar for "right material, right environment" is quite low. Children expect to be bored in classes, and even amateur attempts to make it interactive and help them discover surprising things on their own makes a big difference in how they get involved with the course
7/ But the biggest source of gratification for me was the things the possibility, however small, that this might make an actual long-term difference to some people.
Here's hoping that this kid becomes a terror in their WhatsApp groups 😂
8/ And here's to new, improved conversations at the family dining table 😂
9/ Here's a kid whose faith in "the authorities" has now been eroded, and hopefully that will make him/her a better citizen
10/ And another whose level of belief in advertisements by big companies has fallen, and hopefully that will make him/her a better consumer
11/ It is even more satisfying when the kids
▶️ Realize that things are rarely black-and-white
▶️ And are able to articulate it so well
12/ And the best is when they learn empathy
13/ It warms my heart to teach this course to such students. There one more batch starting next Monday (4 sessions of 1.5 hours each, Monday to Thursday):
If, like me, you're confused about the Oxford/AstraZeneca (Pune-walla!) vaccine, which is 70% effective, but also 90% effective, then here is an explanation. 🧵
The Oxford vaccine requires two shots one month apart. The original design called for two equal shots. However, someone made a mistake and a small fraction of the volunteers got only half a dose in the first shot, and the full dose in the second shot.
🧵
Later, analysis of the data showed—to everybody's surprise—that the ½+1 dose regimen was 90% effective and the standard 1+1 dose regimen was only 66% effective.
The average of these two regimens across all volunteers is 70%, and that is what has to be reported 🧵
As a child, I always wondered why Indian words like राम always got written as "Rama" in English. To me "Ram" seemed like a much better fit for the pronunciation. I thought it was because of British arbitrariness.
Only recently I learnt the real reason for this. /1
Consider गम. How would you pronounce it? Like the English word "gum" right? As a Hindi/Marathi speaker, I can't imagine any other pronunciation.
But, for a Sanskrit speaker, things are different. गम् is pronounced "gum". In गम the full म is pronounced, so it becomes "gum-uh" /2
The extra "-uh" sound which is the difference between गम and गम् is called a schwa
And modern Indian languages like Hindi and Marathi all have an (unwritten) rule that the schwa at the end of a word isn't to be pronounced
Ok, let's do this. What are good YouTube channels that you watched (or still watch) because they're fun to watch, but you also ended up learning from them?
Only recommendations from people born this century are allowed
Include a link to the YouTube channel, what it's about, and why you liked it. And tag others who could add to the list. Younger kids deserve better recommendations than the ones from the previous century.
YouTube for youngsters: Epic Rap Battles of History. This did more for @ArshKabra's history knowledge than ICSE History ever did.
Recently, I've been stanning @krishashok's fabulous threads and videos on the science of cooking. Practical tips, not just theory. For Indian as well as non-Indian food.
In a completely different way @prachi_ has been cooking and instagramming heartwarming stories of dishes-with-memories-attached shared by her friends and readers over at instagram.com/via_dil/
Follow if you like food, feel-good, feel-bad, feel-better all rolled into one
But /2
But all this has been reminding me of an incident shared by my mom about 45 years ago
My dad was a building contractor in Malegaon, and for some reason, my parents were temporarily staying in a shed on the site. Some of the construction workers were also staying there /3
The gaps between perception and reality are stunning. A thread with some highlights
/1
What's the average household monthly income of the top 1% of the country? Most people think its ₹5L or more.
Reality: it is 85k.
88% of you are in the top 0.5% of the country, and almost none of you know this fact /2
The average monthly household income in India is 22k. For a family of 4.7 members.
People in metros don't realize this because, in the metros, we don’t really have the “rest of India”. 87% of all the people living in metros are from the top 40%. We never meet the bottom 60%. /3
It's Friday afternoon, and everyone is too serious, so let's have some fun.
