Hypothesis

1. “Second-wave adopters” will more likely adopt techniques and tools based on successful peer implementations than institutional implementations.

2. The fastest route to second wave adoption may be to stimulate the entrepreneurial faculty.

Open(?)-Source

Open Source ≠ Open Authoring

“Jetspeed is an Open Source implementation of an Enterprise Information Portal, using Java and XML. The data presented via Jetspeed is independent of content type. This means that content from for example XML,RSS or SMTP can be integrated with Jetspeed!

The actual presentation of the data is handled via ates (sic?) XSL and delivered to the user for example via the combination of Java Server Pages (JSPs) and HTML. Jetspeed provides support for templating and content publication frameworks such as Cocoon, WebMacro and Velocity. Note that outside of regular browser Jetspeed also supports WAP devices.

Jetspeed helps you build portal applications quickly!”

The Problem

Some, including “entrepreneur” faculty find university course management systems inaccessible.

©2004 P. Samson - University of Michigan

The Solution (it isn’t pretty)

1. Identify what you want.

2. Find a someone in the system who uses verbs.

3. Find resources to keep his/her interest.

Summary

1. Middleware has been produced that interfaces

Macromedia Flash® (and Director, HTML, and

others) with the CHEF system.

2. Ultimately this will evolve into a “component”

that any faculty (READ: their students) can use

to build learning objects.

3. The hope is this will open doors for other

faculty to author their ideas.
