… and what can we do about it?

If we plot the total number of new covid19 cases in India over days, we see a pattern such as this:

India total number of cases in thousands over time

This is by now a familiar story where we see a sharp rise in the number fo cases starting somewhere in March of 2021, rapidly overtaking anything we have seen so far. If we view the slope as well, we see the sharpness of the rise in the number of cases from a year ago, when it was rising gently. …

Oh dear!

From your experience, it seems this VW is neither for the folks as in plebs, nor a great wagon to die for.

This document is essentially a table that answers six questions related to human learning, regardless of whether they are in primary school, high school, universities, or professional learning set ups. These questions are as follows:

  1. How do students understand new ideas?
  2. How do students learn and process new information?
  3. HOw do students solve problems
  4. How does leearning transfers to new situations inside and outside classrooms?
  5. What motivates students to learn?
  6. What are the common misconceptions about how students learn?

So let’s take the answers one by one:

How do students understand new…

Nodes, edges, and mental maps

What Martin, you have done here, is essentially creating mental maps or concept maps. It can be done using free tools such as Freemind, Mindmeister, and so on. Now, another way might be to use post-it notes (which lately I find very useful) and using the free post-it note app, you can take shots of the organisation, and then when you come back for revision, you can reorganise everything.

Sherlock Holmes used _both_ inductive and deductive logic, indeed, as a few commenters have noted, more formally, abductive logic. The process went somewhat as follows in sequence: observation --> inference --> deduction. The inference, rather Sherlock himself was the inference engine, as he raised several theories (he used the word "theory" on more than one occasion), where the theory would be for explaining EVERY fact that he observed. Here is the crux: note that in Sherlock Holmes stories, his observations are so meticulous that he does not omit a single fact. Then he generalises or infers from these facts one or more than one theories which he then tests with hypotheses. This is where deduction comes into the picture, i.e., from generalisable truths to particular instances that he would then test with gathering more facts.

Excellent, greatly appreciate for sharing this wonderful resource:


… a literature synthesis

Yesterday morning we woke up with the news of a glaciar bursting in the Nanda Devi mountains in India and the subsequent glacial burst flooded a village and burst a dam in the Indian Himalayas. This led to loss of life of about 20 people and 200 people went missing. Sorry sights on TV. While this did not really make international headlines, the question would be whether this was expected or what is the likelihood of this occurring again?

Unfortunately, this was not unexpected. In all likelihood, this will occur again. We only do not know…

… build a model of reasoning from the canon of Sherlock Holmes

We are going to read the canons of Sherlock Holmes in this Medium essay and we will put together the principles of Holmesian observation and investigation. Then we will analyse how these principles can help us to put together a plan of deduction and inference in our practical lives. …
