A A ScalableScalable GIS Education Program GIS Education Program

• High Schools

• Community Colleges

• Universities (four years undergraduate and graduate study – M.A., M.S. and Ph.D. programs)

• (Seamless GIS Education Integration)Career Ladder for different levels of GIS professionals

ProblemsProblems

• Different school levels have different resources and GIS lab setting. (High school: no GIS software/hardware, community college: small GIS labs, few instructors, etc.)

• Lack of entry-level GIS courses for curriculum articulation (GIS courses in Community colleges (techniques-oriented) are quite different from Universities (theories and research-oriented).

• Need a Web portal for sharing research findings and publications to the GIS education community (K-12, community colleges, and Universities).

Web-based GIS AdvantagesWeb-based GIS Advantagesfor high school teachers and students

• Avoid the complicated (and often expensive) software installation in traditional GIS.

• Students can utilize a Web browser to access maps and GIS from anywhere (schools, homes, or libraries).

• Combine with Multimedia (sounds, animation, and 3D) in an integrated Web environment.

Web-based GIS Learning Modules for High Schools

• Provide Web-based GIS exercises for existing High school courses in Geography, Earth Science, Biology, or Mathematics.

• Rather than create a brand-new courses for high school students. (Difficult to implement a new course in current high school schedules)

• Teach ________ with GIS (First Step) • Teach ________ about GIS (in the future)

• Mobile GIS refers to an integrated software/hardware framework for the access of geospatial data and services through mobile devices via wireline or wireless networks (Tsou, 2004).

(Notebooks, PDA, Tablet PC, Pocket PC, etc.)

WHY mobile GIS – Field works: data collection and validation

process, coupled with GPS and wireless communications.

– Real-time update / change– Global Positioning System (GPS) integration.

ChallengesChallenges

• Need to develop evaluation methods for Web-based GIS educations and Modules(How effective?)

• Cope with technology changes (Web technology changes every month). How to migrate from old technologies to new tools?

• Supports from administrative level.
