Be sure to join us on Friday, December 2nd for a Project MOSAIC M-cast at
noon EST (11:00am CST, 9:00am PST) entitled "Coupled oscillators: Joggers,
fireflies, and finger coordination" by Tanya Leise of Amherst College

Abstract: I'll describe a simple oscillator model that can describe the position
of a jogger going around a circular track, a firefly blinking on and off, or the
motion of a finger waving back and forth. We can add a second oscillator to
model two joggers, two fireflies, or two fingers trying to coordinate their motion.
I'll demonstrate how to use some basic analysis involving derivatives to analyze
the various scenarios, emphasizing the role of derivative as rate of change.

Tuning in to an M-cast: Instructions

M-casts are broadcast using the ReadyTalk computer conferencing system.

1. Direct your browser to the ReadyTalk web server
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.  You must dial in for the

The audio is two-way: a conference call that supports the seminar style of
the event.

What's an M-cast?

M-casts are 20-minute seminars broadcast over the Internet on the 2nd, 4th,
and 5th Friday of each month.  They are part of Project MOSAIC, an
NSF-sponsored initiative 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.

There are other M-casts organized by the MOSAIC Project
(http://www.mosaic-web.org) on a variety of interesting topics. We encourage
you to join in on the conversation and discussion for any or all of them:

December 16, 2011 Roundup of resampling methods: simple technology for
introductory statistics
Nicholas Horton (Smith College)
Time: 2:00pm Eastern (1:00pm Central, 11:00am Pacific)

Abstract: Resampling based inference (bootstrapping and permutation testing)
plays an increasingly important role in introductory statistics courses.
But instructors and students have been hampered by the lack of easy to use
interfaces to these approaches.  In this M-cast, I will discuss the
advantages and disadvantages of several implementations, then facilitate a
discussion about the joys and challenges of teaching these concepts.

What's Project MOSAIC?

Project MOSAIC (www.mosaic-web.org) 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.
