Okay - I've been thinking of changing how I use the review days in class. In the past, I've given free response questions (since we've only looked at one of them so far, although there is a reason for that - most FRQ cover more than one of our units, so we couldn't keep going on them...) - timed the response, graded them overnight, gone over them the next day in class.
Since I don't care whether I take them for a grade or not, and since all of you have at least one more AP exam than this one, I'm seriously thinking of changing that. I could give a FRQ a night for you to look at and attempt, and we could go over it the next day (with the College Board scoring sheet so you know how it would be graded) and then we could review the most important parts there and look at some other FRQ or m/c. No timed writing, in other words, but you'd have to do some on your own at night if you wanted to get the full experience.
Or - we could do FRQ at night with m/c practice during the class period.
Or - we could do FRQ in class with m/c practice as homework.
Or - we could do ...other things, as suggested by you. :) We are down to 10 school days to the national exam and I want to use them as wisely as possible. After the unit 4 test, we are down to 6 school days.
I'm open for any suggestions - this is your test, your college credit. There are WAAAAYYY too many of you, though, sitting there saying "I'm not going to pass the national exam anyway, so it doesn't matter." These tests are NORMED - that means that you only do as well as the others taking the test. STUDY!!! You can do this - you can pass - you can get the credit. You know more than you think you do - you just need to review it so you can recall!
Rah rah rah! There's my cheerleader imitation. That's as good as it gets. ;)

well. I am thinking about the things we discussed today in class and I am still trying to get down some of the differences. Would gum be both excludable and rival? So that would be private right? Because wouldn't gum be like kleenex? I don't know all I could think of was gum the whole time you were teaching today, wondering what kind of good that would be.
will we be getting practice frq and multiple choice questions to take home in the next week and days? I think I would like practice with the whole test so I know what all to expect and how much sleep to lose over this ;) just kidding, becaue I am going to study. I haven't lost hope. Well I did But then I retook that test and I saw the light.
you saw the light! :)
Yes, gum would be excludable and rival, a private good. I can stop you from using it (either from buying it, using mine, or having it in the classroom), and if you use it, I definitely don't want it. Pretty much anything that you own would be considered a private good.
After the unit 4 test, I will be bombarding you with all kinds of things to take home and work on in class. We will be reviewing, practicing FRQ, m/c, diagnostics...all kinds of fun!
I'm just waiting until after the test because we need to finish up this last stuff first. I'm trying to keep the confusion down as much as possible.
thanks for the encouragement, mrs. m.
I was looking over some review questions, and what exactly is the difference between diminishing returns and diseconomies of scale? Is diminishing returns simply a matter of quantity where diseconomies of scale is related to marginal costs?
Diminishing returns actually looks at over time, how much of X is happening. In almost all cases, the more you do something (the more you make, the more you buy), the less utility (pleasure) you get out of it. That's diminishing returns.
It's actually tied more closely to economies of scale rather than diseconomies of scale. With economies of scale, look at a LR ATC curve. The lowest point is constant returns to scale. Anything to the left of that point show economies of scale - that as Q increases, ATC is falling. Anything to the right of constant returns to scale is a diseconomy of scale - that as Q continues to rise, ATC starts rising again.
