IntroductionIntroduction
What do we know about how people read?
How do we use “ecological” information?
What do we know about the processing of symbolic and pictorial information?
What do we know about preattentive processing?
What do we know about memory? What do we know about conflicts?

Developed by MIT’s Center for Advanced Educational Service, PIVot combines streaming video, textbook material, lecture transcription, simulations, and problem sets in a unique approach to tutoring. According to Richard Larson, principal investigator on the project, it’s designed to enhance the learning experience for students, supplementing rather than replacing lectures and book learning. This “deep nonlinear learning environment” is driven by a database engine that personalizes the tutoring experience for each student who uses it. PIVot incorporates a number of unique features.

Browser-based authoring also helps shrink the time and effort devoted to content creation and distribution, so companies can concentrate on other management functions. “We have browser-based Web authoring, but we see it as one of many processes that are required to have a collaborative e-business solution,” says Scott Zirbel, director of sales and marketing for Exterprise. Exterprise’s ActiveMarket is aimed at large online marketplaces, giving them the ability to manage the entire process of content creation, submission, review, approval, and publication.

Web-page creation long ago advanced beyond the realm of the Webmaster. Programs such as Microsoft’s FrontPage gave the great unwashed a taste of site building. But as companies continue to decentralize their content creation and management, online communities and marketplaces are turning to browser-based programs that let system administrators set access rights for individual users so that employees—or business partners, portal members, or ASP customers—can edit their own pages, leaving professional Web-site creators free to focus on more sophisticated tasks.

A “Dozen” PrinciplesA “Dozen” Principles
Recognition is easier than recall There are visual shortcuts to awareness
(Triesman) Scripts and schema seem to explain
important aspects of cognition (Shank) People use both functional and
structural models of the world It is possible to encode knowledge in
the world (Gibson) It is clear that people enhance what
they perceive (Marr)

A “Dozen” Principles (continued)A “Dozen” Principles (continued)
There is evidence that people process information both propositionally and analogically (Shepard)
Working memory and the nature of attention make multiple high level processes difficult but do not interfere with automatic processes
There is evidence that memory is organized so as to support “prototypes” (Rosch)
One of the easiest ways to learn is through analogy and metaphor
Color can aid and interfere with symbolic processing
