  1. Web Site Usability Study John Gottfried Spring 2008

  2. By way of illustration… And there are, well, other Web sites… There are really good Web sites…

  3. Web Site Evaluation • Compatibility Testing • Interaction among components (browsers, computers, operating systems, printers, etc.) • Security Testing • Checks for unauthorized access to system • Functional Testing • Looks for broken features or functions • Usability Testing • Does the user find navigating the site difficult, unpleasant or inefficient? Kaner, C., & Fiedler, R. (2005). Testing library Web sites for usability. Knowledge Quest, 33(3), 29-31.

  4. Web Site Evaluation…Why Not • Time consuming • Can be expensive • Intimidating process for the uninitiated • What are you measuring? • Inconclusive (results, but no solutions) Benjes, C., & Brown, Janis F. (2001). Test, revise, retest: Usability testing and library Web sites. Internet References Quarterly, 5(4), 37-54.

  5. Web Site Evaluation…Why • Overcome subjective values & politics • Stakeholder input and feedback • Practical decision-making • Reduce cost of development & support • Justify investment • Marketing & public relations --Benjes, C., & Brown, Janis F. (2001). Test, revise, retest: Usability testing and library Web sites. Internet References Quarterly, 5(4), 37-54. --Dicks, R. S. (2002).

  7. Study background • Indiana University Libraries, Indianapolis, IN • Urban Campus, 29,000 students, IU Medical School • Purpose—evaluate effectiveness of new Library Web site • Recruited 30 Volunteers ($10 Campus Cards) • Method (Battleson, Booth & Weintrop) • Basic information about Ss. Role, computer and library use • Completion of 10 common Library Web Site tasks • Recorded time, task completion, comments and # of pages • Ss. comments and reactions to Web Site Battleson, B., Booth, A., & Weintrop, J. (2001). Usability testing of an academic library Web site: A case study. Journal of Academic Librarianship, 27(3), 188-198.

  8. Participants • 2/3 of participants were undergraduates • Only 1 student in first semester, 2/3 over one year • All but one visit the Library at least once per week & over half use the Library Web site at least once per week • All but one were confident computer users, and all but one use the Internet daily • Heavy users, not novices

  9. Student Comments • Not many specific comments • Overall, the Web site was received enthusiastically (25) • Helpful, useful (6) • Biggest negative was finding articles (11) • Several suggestions for a Help button for articles • Biggest positive was Ask a Librarian (11) • Many users were not aware of this page • Unaware users said they would use it now • International students: need instruction sessions • Instruction: • Challenging first-year class/instructor a key factor for extraordinary overall performance • In-class librarian instruction a key factor task proficiency

  10. Key Implications for Teaching, Learning and Research • Students need considerable help finding articles and periodicals • Placement and awareness of subject guides • Fast, easy access to research help • Instruction is a critical component of successful performance • In-class librarian instruction for task proficiency • Curriculum-based for overall effectiveness • International users may need specialized instruction in basic terms and concepts 

  11. Key Implications for Web Site Design • Eliminate the use of confusing terms and jargon • Check user comprehension of terms • Recruit diverse sample of students, including international students • Use icons and images where possible • Key functions must be clearly marked and labeled, and easily accessible • Students are currently required to “drill down” too far to find articles

  12. General Recommendations • User focus • Research, customization, clear language • Web design • Easy-to-use, well-maintained, limit complexity • Value added • Assistance, annotations, tutorials, subject guides • Links to free materials • e.g., other libraries, open Web content Rich, L.
