REFLECTIONS

 

Monday, August 2

 

GeoGebra is one impressive app (especially for free!). I learned about GeoGebra last summer when I attended an AP calc institue at OU Chillicothe and one of the other participants (Rich Dunn) had just finished the GeoGebra training.  The instructor actually gave him some teaching time and he was showing us what GeoGebra could do. Everyone was really impressed and I decided right then that I would take the GeoGebra training the next summer, and here I am. I am really looking forward to learning as much as I possibly can this week to use in my classes, and taking back info to share with the other math instructors in our district.

Today we continued to learn the seemingly endless features of GeoGebra.  I created a variety of calculus and pre-calculus applets (rough versions - need some cleaning up) and I plan on using them in my classroom.  Tomorrow I hope to explore the boolean commands, as well as the statistics capabilities of GeoGebra, although my students and I currently use Statcrunch and I'm doubtful that GeoGebra will serve my purposes as well.

Learned a lot today about customization of Geogebra, including creating custom tools and customizing the toolbar - I want to experiment some more creating custom tools.  I also uploaded my mean value theorem applet to my AP Calculus Moodle site and it worked great. I can see that I will be doing A LOT with GeoGebra and Moodle together this year. I played around with boolean operators and conditional hiding/showing, as well as the sequence commands - very powerful.  I did not explore statistics capabilities fully yet - I guess that will be tomorrow's rask.

 

Thursday, August 5

 

I spent most of today working on my fundamental theorem applet. It is basic, but I think it demonstrates the connection between integration and the antiderivative.  I also played around with creating a sampling distribution using the randomnormal command.  I was surprised at how robust the spreadsheet was in certain aspects. I can see myself using GeoGebra in a limited capacity in my Stats class. I started working on a applet to demonstrate the disk method of finding volumes of solids of revolution - hope to finish it tomorrow.


SOME "ROUGH" WORKSHEETS

 

 

 

 

 

     
     
     
String Art    Bezier curves on an equilateral triangle. Doesn't do much, but it's fun to watch. 
Mean Value Theorem   This applet demonstrate slides a tangent line over an interval and indicates where the MVT is true. 
1st Fundamental Theorem of Calculus   This applet visually demonstrates the connection between integral calculus and differential calculus.
DIsk Method    This applet demonstrates the Disk Method for finding the volume of a solid of revolution.
