**Who I am.**

I’m a mathematician currently involved in research into online teaching, especially for mathematics. My particular interest is in discovering effective techniques for integrating mathematical meaning into onscreen mathematical communication and interaction (for details, see this post to the WebMath list). More generally, I'm interested in all forms of web-based communication, particularly in visualization and other new or non-verbal forms of communication. I am also an Adjunct Professor of Mathematics at SFU.

**Some projects and prototypes.**

- Interactive calculus. A prototype based in part on the educational research of John Sweller, University of New South Wales. The relevant part of the theory: since human aural working memory appears to be largely separate from visual working memory, using both to convey content decreases the learner's overall cognitive load and thus improves learning. The demo, a multimedia-enhanced PDF file, uses several tactics to decrease cognitive load, most notably short learner-controlled voiceovers with explanation, instructions, heuristics, motivation, etc. each targeted to an adjoining diagram or calculation. (Warning: large file. Best to download it first.)
- BinderBabies. A BinderBaby is a freely distributed prototype web notebook interface for online educational materials. My intent was to make an easy-to-use presentation framework for non-specialists with limited resources (authors need only a basic HTML editor). BinderBabies are part of a more extensive project: the BinderMinder, a mechanism for locating and organizing notebooks and other materials into electronic Binders.
- Poincaré. This is an early (1997) web-based interactive module for Poincaré geometry. Geometer's Sketchpad provides the interactivity: click a GIF and a 'live' Sketchpad version of it opens automatically ready to be manipulated with specially designed Poincaré tools. The intent was to encourage students to develop an intuitive, visual and kinesthetic understanding of Poincaré geometry through interacting and experimenting with live sketches.

*Working the angles*. A Flash-powered interactive tutor for finding the trig. functions of basic angles. Inspired by my frustration with students who can’t. - (in the works) A QuickTime version of the calculus demo above, with video, animation, ...

**And a paper.**

- Designing Interactive Mathematics, a paper presented at ATCM 2000. “There is a need for a ‘grammar of interactivity’ as a tool for onscreen communication in much the same sense that the grammar of a language is a necessary tool for verbal communication. ... effective mathematical communication also requires a careful examination of the intrinsic mathematical nature of onscreen objects and how users interact with them”. Contains some preliminary principles for interactivity design.
