The Problems
•Lack of computers in partner schools•Preceptors asking for support in the office•Students need to access content “on the
go”
Can a Mobile TUSK begin to address these issues and provide new opportunities for learning?
![Page 13: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/13.jpg)
“I think it's time that we recognised that for the majority of the world's population, and for the foreseeable future, the cell phone is the computer, and it will be the portal to the internet, and the communications tool, and the schoolbook, and the vaccination record, and the family album, and many other things…”

Cellular phone growth
•300 million computers vs 3 billion cell phones in the world (metcalf)
•Spending in the developing world on telecommunications outstrips other sector including health care (Hammond)
•Nearly 100% of students at our partner schools have phones, less than 10% have computers
![Page 15: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/15.jpg)
Mobile Learning
•Mobile represents and opportunity to reach learners – especially “just in time learning”
• Increasing research on mobile learning including situated learning (Naismith)
•M-learning is not just about readily accessible information -- it opens up the possibility for the delivery of audio information, interactive learning and assessment, and real-time distance collaboration. (coe.sdsu.edu)

Design Challenges
•Mobile provides different context for information access
•Screen size•Load Time of complicated pages•Storage space •Many phone types
![Page 21: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/21.jpg)
Initial Design Considerations
•Understand user patterns (from survey)•Fewer links per page then web version•Allow more scrolling in favor of larger
text size•Simplified pages
![Page 22: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/22.jpg)
Usability Test – phase 1
•Students presented with 3 designs and 3 scenarios
•Students asked to narrate choices•Users timed and errors noted for each
task•Students were asked to state preferences
for each of the three options with supporting reasons
![Page 23: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/23.jpg)

Phase 2 Usability testing
•One interface created incorporating features that would address errors/likes/time from phase 1
•Phone emulators used•Statistically every user improved from the
averages of the first usability test in time to completion and in total errors occurred
![Page 25: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/25.jpg)

Implementation Changes
•We can support all multimedia (flash coming along)
•Whoops – forgot about faculty – fixed that•Opera mini browser works well for older
phones
![Page 32: Susan Albright, Daniel Walker, Theodora Hadjimichael,Daniel Jozwiak, Benjamin Schwartz, Mary Lee](https://reader035.vdocuments.mx/reader035/viewer/2022062305/56814bec550346895db8cb5c/html5/thumbnails/32.jpg)
The Future• Mobile Discussions coordinated with web-based
representation of same discussion▫ Discussions can easily be mobile – don’t need to
worry about integrating sms messaging with discussions
• Mobile Data collection – case logs the first step• Off-line data collection (our students and
developing countries)• IVR – interactive voice response• Determine need for additional phone specific
applications
