Calculus & Mathematica anyone?

I've been thinking about the Calculus & Mathematica project by Jerry Uhl et. al.  I used some of his work years and years ago in the early days of Mathematica when we had a copy at my HS.  This project was very useful for students to learn Calculus at their own pace in a lab setting.
I wonder if anyone is doing something like this in addition to the traditional Calculus AB or Calculus BC class.  Alternatively, is someone using something other than Calculus & Mathematica, maybe some other courseware?  Any pointers or success stories out there?  Inquiring minds want to know!

I'm looking into setting up a SAGE lab myself....

Meeting V

Today's Aim: Install Fest!
Tonight's Reading: Building Parallel Programs, Chapter 5
This Week's Research: PVM and MPI environments
Attending Tues: JeremyA, SteveB, DevinB (fedora install fest)
Attending Thurs: JeremyA, SteveB, DevinB, ArthurD (bzflag stuff)
 
This Tuesday we are finally reinstalling the Linux Partitions on all the PC clients in our PC Classroom.  We have 64-bit AMD Athlon dualcores, so we are using the Fedora 11 64-bit liveCD to do the reinstall over the KNOPPIX 5.3.1 32-bit liveDVD installation we currently have.  

We will also have a make-up meeting this Thursday when we will burn a class set of the Fedora 11 Games liveDVD for our BZFlag LAN Party the day before turkey day!



Happy Clustering,

"Look Ma, No Calculator" went well I think...

Wow, I hope I didn't try to ram too much into an hour and a half....  Sorry if I went a bit fast, but I had a lot to share with you!  Believe it or not, I only just scratched the surface of Scientific Computing.  Many colleges are starting departments in this new field which is a merging of Applied Math and Computer Science used in real-world math and science applications on super computers.  BTW a super computer can be a single PC with multiple cores setup to use all cores on one problem.  Also, a super computer can be Linux Cluster with several PCs linked together to solve one problem.  Or, a super computer can be like Shadowfax (avatar below), a mix of both (25 compute nodes, each dual-core) known as a hybrid cluster!
 
If this is all too new to you, don't feel bad.  I've been teaching programming since 1975, I've been perfecting Room 429 (aka Shadowfax) since 1985, I've been using Graphing Calculators since 1990, I've been using Linux since 1995, and I've been trying to get a Scientific Computing Lab course in place at BSHS since 2005.  You guys just have to play catch up!
 
If you are interested in any of this, you should google Scientific Computing, Computing Sciences or Computer Algebra Systems in general as well as the Mathematica, Maple, MATLAB or S-plus programing environments in specific.  Also, you can get tutorials on SAGE at http://www.sagemath.org and work online with SAGE at http://www.sagenb.org where you can create your very own free account in seconds or just use your SAGE liveCD!
 
BTW, remember FLOSS (Free Linux Open Source Software)?  SAGE, Octave and R are FLOSS equivalents to Mathematica, MATLAB and S-plus respectively.

Look Ma, No Calculator!

Welcome to SDD 2009.1103:  
This will be a "Show & Tell" session where I show you how I teach math using technology without ever touching a calculator!  In Part I, I'll show you the old fashioned way using a TI-83 Graphing Calculator.  If you have a TI-83, please use it to follow along!  But that's SO last century...  So, in Part II, I'll show you how we do things in my classroom now-a-days using a Computer Algebra System!  I'll leave it up to you to pick and choose any techniques you think you may use in your classroom.


PART I: I will record a math lesson on something simple like quadratic equations in Windows using Smart Recorder + Smart Notebook + VTI as a Windows Media File for uploading to my FTP site (30 min).  


PART II: Then we'll reboot all the PCs in Linux with the SAGE CD and show how the same lesson can be done with a Computer Algebra System.  You can follow along using your own PC!  I will record this part of the session with http://screencast-o-matic.com and upload it to youtube (30 min).  


PART III: In summation, I'll share my website,  blog, youtube channel and zazzle digital art.  I will also show everyone how to use http://www.sagenb.org with any Mozilla clone so they won't need a SAGE CD (15 min).  
PARTY FAVORS: Everyone goes home with my URLs and their very own copy of the SAGE CD!

Meeting IV

Today's Aim: Burn Fest II
Tonight's Reading: Building Parallel Programs, Chapter 4
This Week's Research: openMOSIX & openMOSIX distros
Attending: JeremyA, SteveB, DevinB, ArthurD 

We burned 30 Fedora 11 64bit and 30 SAGE 4.1.1 liveCDs.  Surf on over to http://www.sagemath.org to download your own copy of the SAGE CD.  We tested all the CDs and found the SAGE CD very responsive for use in my demonstration at Staff Development Day this Tuesday!

BTW, my Computing Independent Study class is nicknamed CIS(theta) - see avatar below.
