Comparison of UCLA system and EarthEd Online:
Strengths of UCLA cpr system:
1) Polished, ready to go system with lots of support.
2) small library of cpr assignments already exists.
Limitations of UCLA cpr:
1) it only supports cpr writing, so is limited in scope
2) no support for image editing. Linking of images is done in html. Students
must edit images in externally, which requires learning another interface.
Strengths of EarthEd Online:
1) broad in scope. Some of EarthEd capabilities that are absent in the
UCLA system are:
- graphics editing and linking
- data modules that allow point and click
creation of data plots and images
- auto graded homework problems
- student feedback surveys
- access to current course grade
2) by Spring, there will be a threaded discussion board. I also plan
on adding a discussion screen based on a blog metaphor. This will allow "Just
in Time" teaching
techniques and facilitate shorter writing assignments with more unstructured
student interaction and discussion. These will also embed the image
editing and linking capability that the writer has.
Weaknesses of EarthEd:
1) It's a new system and there will be more hassles with bugs
2) Distribution of software requires more planning. Web download will
be implemented, but the large data modules are better distributed on
CD or DVD.
