SetCoords Command   SetCoords SetCoords( <Object>, <x>, <y> ) Changes cartesian coordinates of free objects. This command uses values of the coordinates, not their definitions, therefore the object stays free. Note: This command now works for Sliders, Buttons, Checkboxes, Input Boxes, Images. If “Absolute Screen Position” is selected then x, y are in screen pixels. My template has stuff like this SetCoords[I1_1,x(%1),y(%1)]”,”SetCoords[I2_1,x(%2),y(%2)]”,”SetCoords[I3_1,x(%3),y(%3)] […]

“This.” That is a link to a Geogebra animation of a machine pumping up a balloon full of air. I had, on my drive, dismissed those kinds of animations — precisely the “filling up” animation. I am NOT going there.  Yet. I’ve been disillusioned often enough by geogebra not to interrupt even after I see […]

Interesting American Institutes for Research article in EdWeek about inclusion and the idea that it simply decreases actual instructional time — not because the sped students are “slower” but because of behavior issues. It basically says teachers don’t have good training (‘lack knowledge of positive classroom management techniques,” etc.)… … but otherwise … yea, I’ve […]

Let’s talk about this on general terms… So a student comes in and … they’re struggling.   There’s a lot they seem to know… strengths abound… but wham!  they keep crashing and burning… … how much is the math model? … how much is oh, symbol overload (e.g., students who will have no trouble w/ the […]

So I make a point like it says to do in the “how to make text” because I want to make text that is attached to a point so it moves when I drag it. It says “Then, a dialog appears where you may enter your text, which can be static, dynamic, or mixed.” Now, […]

Geogebra.   “Lists” are a lot like arrays, tho’ the first element is list(1) not zero; zero will get “undefined. No, I still have no idea how to actually SET THE STUPID X AXIS TO THE SIZE I WANT.   I mean, I know how to set it but it changes if I so much as move […]
