Redesigning a Content Delivery System, TUSK, for the Small
Screen: Bringing a Web-based LMS to the Small Screen, a Ubiquitous Appliance in the
Developing World

Agenda
•What is TUSK ?•Why TUSK Mobile?•Methodology for redesign •Design considerations•Implementation •Next steps
What is TUSK? Tufts University Sciences Knowledgebase
Features
•Tools for ▫Content authoring/upload/replacement▫Quizzes▫Patient Logs▫Virtual Patients▫Evaluation▫Curriculum Management▫Collaboration▫Personal knowledge management▫etc
Leverage faculty expertise and optimize intellectual capital
Learning object repository
Reuse
Robust indexing and search and retrieval
Robust authoring tools

schools
Index Search and Retrieval: UMLS Controlled Vocabulary
Content Management Tools
•Create folders •Upload any multimedia•Reuse TUSK content•Create links across any TUSK content•Create external links•Create API’s to external links•Require metadata for all content
Tufts University Mission: Global Health and
Internationalism
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?
“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…”
Joel Selanikio is a physician and co-founder of DataDyne.org, a non-profit creating open-source software for public health and international development BBC, Jan 2008
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
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)
Mobile Development Plan•Contract with students from human factors
major at undergrad campus•Background research on design
considerations•Survey current TUSK Users•Usability testing•Final Design Recommendations•Design implementation•Testing in the US and in developing countries•Research other mobile applications

Design Challenges
•Mobile provides different context for information access
•Screen size•Load Time of complicated pages•Storage space •Many phone types
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
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
3 Versions of Log in Page
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
Log in Page
•TUSK logo included with alt text: to connect mobile TUSK to website and deal with phones with images turned off
•Password field masked
•Remember me box checked by default
•All element appear on screen – no scrolling
Main Menu Page
•All entries numbered and assigned corresponding access key – Alternate plan for phones without functionality
•Entries sorted by frequency of use or alphabetically
•Announcements option to alert to new message
•Search and logout option should be on the list
Announcements Page•Announcements sorted by course with options by date
•Courses color coded to match website
•Number of ann. Limited – by course and age
•Length of announcements limited – truncate or abridge with access to full length. Length not to exceed 80 characters – ~3 lines on the screen
Schedule
•Default to today’s schedule and next day. Days diff by bolded, italicized or underlined text
•Course color coded
•Option to select day in past or future though either calendar or entry format
Content Types•Content types divided into groups to reduce density with a link to switch between types
•Search option to locate additional/related/new content
•Content arranged in logical order assigned by content creator
Images
Implementation Changes
•We can support all multimedia (flash coming along)
•Whoops – forgot about faculty – fixed that•Opera mini browser works well for older
phones
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
