How Does This Button Work? by Chris Sangwin
Just about everyone has wondered: "How does this button work?" They may not have been thinking of the world of dynamic geometry, but Chris Sangwin of the University of Birmingham has been thinking about just this subject.
He recently contributed an interactive learning resource to the Journal of Online Mathematics and its Applications, and his work will no doubt command the attention of mathematics educators. Along with providing details about this nuance of dynamic geometry, the article contains several interactive applets and two short video clips. The article also contains contact information for Sangwin, so users can contact him with any queries.

Mathematics for Economics: Enhancing Teaching and Learning Working at the University of Nottingham, Dr. Rebecca Taylor and her colleagues have created this very fine set of resources designed to assist teachers who seek to utilize mathematics in the service of teaching economics. Visitors can learn more about their work in the "About the Team" section, and they can also view a summary of the project's work so far.
The real heart of the site is contained within the "Resource Room", which contains streaming videos, teaching and learning guides, and a question bank. Visitors may wish to start with the question bank, which contains files that can be used in problem sheets, assessment exercises and tutorials. The exercises include those drawing on algebra, number theory, and differentiation. Moving on, the site also includes teaching and learning guides that address linear equations, finance growth, and either other topics.
