Today, Teaching with Blackboards and Slides. And also several questions from last time.
-
And related to that, a handout - which I've put online - which is
-
how to make a lesson plan.
-
So I'll do all that through the questions
-
Ok, now just a quick bit about lesson planning
-
because a couple of you pointed out you'd like to know more about lesson planning
-
And then reminded me that when I taught the chemistry TA workshops
-
I actually gave everyone a handout on how to plan a lesson
-
So I've put that handout online and I'll just show you what it looks like here
-
So this is basically the sheet i use for planning any kind of lecture recessitation.
-
Ok so, at the top we need some kind of course and date
-
And then the objective
-
So that's quite important
-
You'll see the exact sheet
-
And there's a .PDF file. You can just use it yourself.
-
There's a course objective
-
for that particular section
-
And that relates to your overall goals for the course.
-
So for example, in this problem, my objective might be something like
-
To show that easy cases.. in fact this was my objective...
-
I wanted to show that easy cases.. extreme cases... are useful not just for checking formulas
-
but also for generating formulas.
-
Ok, so, I write that on the top so I remind myself
-
Why am I here?
-
What am I doing?
-
Then, there's a 3 column table
-
Basically you just plan items in your lecture
-
The first column is minutes... how long you expect each thing to take
-
And then your... here is your... middle column, most of the spaces..
-
What's your goal in this local part of the lecture and what are you gonna do for that?
-
So here is my overall objective
-
And my local goal may be just this example
-
Getting that one third
-
And then here, the third column is props
-
Ok, so there's actually a piece here too
-
So props are anything I need to bring
-
So I just stick that in the margin
-
Ok, bring the cones or the pyramids.. whatever they may be
-
And so then when you're planning your... when you're filling this piece in about what to bring
-
you just scan down all these columns on your, this last column
-
And just write everything here
-
Ok, bring cones
-
Homework 3, Solution set 2
-
Ok so now, at a glance
-
Before you go to your session
-
You review these two things
-
Make sure you have everything
-
You know why you're here
-
But then here you're gonna follow your script
-
Which is a loose script
-
It's not exact word for word script
-
It's.. maybe a few equations
-
Suppose there's a question:
-
What is this constant?
-
Ok, so that's my overall what I'm gonna do for say.. .10 minutes
-
And then I break it into sub-questions
-
Ok, what is H & B? How many pyramids do I need?
-
What's my goal shape?
-
So these are questions I ask students.
-
And for each one, I write down the minutes
-
Maybe in parentheses.. because I put the total up here
-
Ok so now when I've done my two or three pages..
-
And by the way, I find just the level of detail I use, if I ever go beyond three pages
-
I never get to that material
-
So, it's just sort of for a security blanket
-
by the time I'm beyond three pages
-
It depends on how detailed you write these things, but I've generally found that's where I am
-
And then you estimate the time
-
And what you'll find, the first time you do stuff, you'll massively underestimate the time
-
You'll be off by a factor of two
-
So in other words, if you thing it'll take five minutes, it will really take ten minutes.
-
And that's true even after you take into account this rule.
-
Sort of.
-
Ok so then you put down all your minutes on this page, the next page
-
You add them up
-
And you make sure you're not over fifty or whatever the amount is
-
And then what you'll find what you thought was fifty
-
Really is gonna take you one hundred and thirty
-
So the next time you evaluate the minutes
-
You'll have a better idea
-
And you'll find yourself actually tuning your time sense pretty well
-
So now I've got my time sense
-
So that I really don't need to put the minutes down
-
Because I can just do it by the number of pages
-
Three pages, too much
-
So you'll find for your own writing detail level, how many pages to use
-
Ok, now the other point is.. where do these questions come from?
-
Ok, well this is a way you can turn any regular lecture into an interactive one
-
So, suppose you have a long derivation you're going to do
-
Or some.. like for example, the first way I planned this, I wanted to show people
-
that this was one third over here
-
This three here
-
And the way I was gonna do it was I was gonna draw 6 pyramids
-
Show them in a cube
-
And show the six V
-
And do all this showing
-
Well, first draft, write it all out like that
-
With times and everything, without questions
-
Then, any time you come to something interesting
-
So here... so before you have tell.. so now you look at your sheet
-
And you say hmmm... where did something interesting happen?
-
Hopefully, there is at least one point
-
Because if there isn't, maybe you shouldn't be giving the lecture at all
-
Alright.. so now.. let's just saw by instruction, you found some interesting things
-
Ok, so... wow that's interesting.. it's interesting that it makes a cube.
-
It's not obvious
-
You know.. so.. just think... where does something require thought
-
and you're short circuiting the thought by telling
-
So then you just put a... what I do is I have a green pen... and I turn it into a question.
-
So I circle it in green and write "ASK" next to it
