Very interesting talk but I wish there were more examples of perceptual
learning related to programming. Does anyone know of any websites or books
using this approach?
It is not surprising to learn that perceptual learning works for
identifying the sex of a baby chicks since it is based on a direct visual
analysis (i.e. perception). On the other hand, it is surprising that we can
learn subjects that are largely conceptual (i.e. abstract), like object
oriented programming, by the same means.
Upon reflection, I do believe we learn best by example and this is probably
what Kathy Sierra is getting at. Actually, this fits well with Ayn Rand's
idea of "concept formation" where each concept we hold is built upon a
perceptual foundation. In this case, the 'perceptual learning' approach for
teaching a novice 'for loops' would be to have them practice writing lots
and lots of for loops. After writing hundreds of examples, the student
would have the necessary perceptual foundation to form the concept 'for
loop'.
+Calvin Coolidge The simplest concepts are largely based on patterns as well - and the brain does pattern matching really well. More complex concepts are based on simpler concepts, which are eventually boiled down to just patterns, which our brains handle for us (given the chance). To use your example of loops, over the course of an hour, I'd probably teach the while loop first, and then have the learners spend a few minutes doing some really simple loops before then introducing nested loops. After about 10 minutes on the while loop, they'd then start the for loop. Same again, and after around 10 minutes of that, I'd move on to mixing the two loops for a further 10 minutes. At the half hour mark, I'd move onto do while loops, do those for 10 minutes, and then spend the final 20 minutes doing examples of all three kinds of loops. After they were done with each exercise, they'd be shown the model answer and be moved onto the next exercise. By the end of that hour, they'd probably be sick of loops, but they'd be able to do them in their sleep.
+Lee Jun See the YT trailer for her book and you'll see why she's using the stock photos: https://www.youtube.com/watch?v=tBioIUWEyzo&annotation_id=5f2594eb-f880-43b3-a147-cb2693a5ae5f&src_vid=FKTxC9pl-WM&feature=cards
No kidding. Last Friday, I didn't pass the test for a web developer job I
was applying for, because I f*king SOLVED a problem without knowing how I
did it! They didn't accept the answers such as "I just... know" and "I
couldn't explain how I do it"... I got a big NO!
+Joepet Fernandez No, it's not. To know in detail is wasting cognitive ressources - hello, watch the video! That's why we have invented books. Outsourcing information that experts don't need to have handy anymore, but they have automated it to the point they are applying it perfectly, yet may not be able to explain everything in detail.
So if i pause the video and I go through the comment section engaging in
every post, and then I go back on top and I un-pause the video, I wont be
able to pay as much attention to it? because I burned my attention in the
comment section?
shit I have been using youtube wrong my whole life lol
+CSopo This will be more obvious if you try reading the comment section in an additional window while you attempt to listen to the video simultaneously. I think it depends on your ability to clear your mind after reading the comments, so you can concentrate on what the video has to say without being distracted by what you just read
+Mihail Malostanidis you can just pause the video and type them down..lol its not that hard.
