Please join us for this week's MOSAIC M-Cast.  At 1:00pm eastern time on
Friday, November 12th, Eric Marland (Appalachian State University) will
discuss "Using Difference Equations for Introducing Derivatives"

Over the past decade many calculus texts in the life sciences have
introduced discrete modeling in the early portion of the course.  Why hasn't
this caught on in the standard calculus course?  Should it?  What are the
advantages or disadvantages.  In this M-Cast, I want to discuss these issues
and provide some ideas on how it might be accomplished successfully.

What's an M-CAST?
M-Casts are 20-minute seminars broadcast made over the Internet on the 2nd,
4th, and 5th Friday of each month.  They are part of Project MOSAIC
<http://www.causeweb.org/wiki/mosaic/index.php/Main_Page> , an NSF-sponsored
project to improve undergraduate STEM education by better integrating
Modeling, Statistics, Computation, and Calculus.  M-Casts are designed to
provide a quick and easy way for educators to share ideas, get reactions
from others, and form collaborations. M-Casts are recorded and posted on the
Internet soon after the event.

Wiki pages for materials, discussion, etc.

Tuning in to an M-CAST: Instructions
M-CASTS are broadcast using the ReadyTalk computer conferencing system:
1.  Direct your browser to http://www.readytalk.com  and enter access code
2923887.  This provides the video component of the M-CAST.
2.  For audio, telephone 866-740-1260 and at the voice prompt, enter the
same access code: 2923887.
The audio is two-way: a conference call.  To avoid excessive background
noise, please use the mute feature of your phone until you want to speak.

Recordings of the M-CAST are posted soon after the event.

Project MOSAIC is a community of educators working to develop a new way to
introduce mathematics, statistics, computation and modeling to students in
colleges and universities.

Our goal: Provide a broader approach to quantitative studies that provides
better support for work in science and technology.  The focus of the project
is to tie together better diverse aspects of quantitative work that students
in science, technology, and engineering will need in their professional
lives, but which are today usually taught in isolation, if at all.

* Modeling. The ability to create, manipulate and investigate  useful and
informative mathematical representations of a real-world situations.
* Statistics. The analysis of variability that draws on our ability to
quantify uncertainty and to draw logical inferences from observations and
* Computation.  The capacity to  think algorithmically, to manage data on
large scales, to visualize and interact with models, and to automate tasks
for  efficiency, accuracy, and reproducibility.
* Calculus. The traditional mathematical entry point for college and
university students and a subject that still has the potential to provide
important insights to today's students.

The name MOSAIC reflects the first letters --- M, S, C, C --- of these
important components of a quantitative education. Project MOSAIC is
motivated by a vision of quantitative education as a mosaic where the basic
materials come together to form a complete and compelling picture.
