  1. Usability Testing T/TAC Online Project Design Team Tsehaye Habteselasie Jennifer Okezie Meredith Riddile Aanal Sheth

  2. Usability in Practice • Incorporates direct user feedback throughout the development cycle to reduce costs and create products that meet user needs (Usability Professional Association) Learnability Efficiency Errors Satisfaction Memorability

  4. T/TAC Online Project- Phase 9 • Online performance support tool that allows users to input, view and search • Local Improvement Plans • Government-funded grants

  5. T/TAC Online

  6. T/TAC Online- School Improvement

  7. Local Improvement Plan Input System

  8. Level 1 Evaluation • Collecting reactions and gauging perceptions • Predicting level of user acceptance

  9. Usability Testing Cycle Expert Reviews Redesign Usability Testing Survey Redesign Launch analysis analysis

  10. Usability Goals

  11. Planning Usability Testing • Solicited participation from target audience • Developed protocols • Developed task scenarios based on usability goals • Level 1 desired results

  12. Schedule of Activities

  13. Expert Reviews • Allowed experts to test system • Asked experts a set of predetermined questions

  14. Expert Review Findings • Organized comments into categories • Calculated frequency of comments

  16. Redesign Before After

  17. Usability Testing • Participants completed task scenarios • Used an observation log • Measured observations • Used Likert scale to measure user perceptions • Ease of use • Efficiency • Usefulness • Acceptable

  18. Task Scenarios One example: • You began your Local Improvement Plan (LIP) for the 2004-2005 school year earlier and now you have collected more information that you would like to add to this LIP. • Add the following information to Section 2 of this LIP: • Add the table that corresponds with the description of Goal 3. This table is titled “Practice_Table.doc” and is located on your desktop. • Add the following information to Section 3 of this LIP: • “There will be a decrease by 10% in the special education teacher turnover rate during the 2003-2004 school year.” • Save your work and select continue.

  19. Observation Log

  20. Debriefing questionnaire • Used Likert scale 1 – 6 1. How do you rate the overall ease of use or difficulty of this system? 2. How would you compare using the online system with creating LIPs the way you currently do? 3. How useful is this system? 4. Would you use this system if it was available?

  21. Usability Testing Findings • Calculated observations and Likert scale responses

  22. Likert Scale Results

  23. Likert Scale Results

  24. Usability Reactions Cutting and pasting is easy! Much easier than current process! You can glean ideas from other LEAs! Standardized format is great!

  25. Surveys • Used in order to reach out to users throughout the state • E-mailed one task scenario and questionnaire to 8 participants
