A little off topic

MathML Strengthens Digital Math TextsDigital texts are moving beyond simply putting pages on a computer screen.In Kentucky, a small pilot study is demonstrating the benefits of this textbook technology for students with different learning styles. Instead of re-creating a complex math problem as a static image file, digital texts that […]

The fence question

So I assigned the classic fence-against-the-river question to my group (you have 200m of fencing, what’s the largest rectangular area you can contain where one side is not needed against the river). We had just started quadratics so they have no real background in it at all. One student solved […]

So a little further

Well, we’re into quadratics now. The one section is doing really well incorporating Maple into their learning process — they fluidly jump back and forth between Maple & OneNote. The other class more stubbornly holds on to doing everything by hand/calculator. I keep struggling to move this section to a […]

Variables

Well, we’ve used the Curve Fitting Tool for the past couple of classes. Lesson learned: it’s best to be descriptive in your variables because using x and y is not conducive to the CFT (it wants to use x as the regression variable).We’re on to quadratics now; I wish the […]

The test

Things that immediately pops up….Having them able to use the TEXT to describe their variables and present their solutions neatly. We focused so much on the math work that I didn’t do enough on using the text component to explain the setup and solution. Sigh…. only so many hours in […]

Leading by the nose? Or breaking a path?

Well, we did a bit of direct instruction (not Direct Instruction, which is completely different… kinda like variables in poorly designed programming languages) where, in order to lead them through using Maple to get a least squares line for a set of data, I had to go through with them […]

And they find another one…

Well, we’ve been graphing now pretty successfully…. when we get to this simple little example:d = 230td = 200t+170.Plot the first, drag the second on to the grid, no problem. Then, we try to zoom/translate to approximate the intersection’s location.Well, Maple decides that we aren’t going to get it. When […]

2nd foray

Having done graphing with Maple the other day, we worked a little bit with solving systems of equations by substitution. One of the students mentioned that instead of assigning names by typing “L1:=y=3x+2” you could avoid the first equal sign and just use a colon.Well, that was okay for graphing, […]

Dipping a toe in…

Okay… well we made an attempt at Maple 12 today… just a brief introduction to graphing. I deliberately did it by assigning names to the equationsL1:=y=3x+2Then I chose to have them graph it implicitly. I’m trying to plan ahead here, so that I can use the names of the equations […]

So it starts…

It begins tomorrow. Well, actually, it doesn’t because the students don’t have their laptops tomorrow so we will just do a “welcome back to school, I’m your teacher, here’s a little activity” without involving any technology. So it will actually start on Tuesday. I’m hoping to get the permission forms […]
