IL2007, Day 1: Putting Evidence-based Practice to Work



Putting Evidence-based Practice to Work, Frank Cervone and Amanda Hollister

Frank:

  • most librarians haven’t been trained in HCI
  • defined evidence-based practice
  • data provides primary evidence for decision-making
  • it’s not “common sense” – different stuff generally happens than what you “think” will happen
  • Ex – doing a usability test, then comparing it with other similar tests to see the larger picture
  • similar to user-centered design
  • SPICE – setting, population, intervention, comparison, and evaluation
  • Northwestern did their first usability test in 2001
  • 2002 – did a catalog usability test – they found that the greatest number of searches that failed were title searches – title search was the default search setting, students were typing keywords into the default search box and not finding anything… so they found some great info from this test
  • overall, site usability has improved – and they can prove it with statistical measures
  • debates about how to proceed are easier – because they have data to fall back to
  • easier to develop a strategy for incremental improvements over time – no longer locked into a tight academic schedule – they can prove the change will be an improvement, so have the go-ahead to roll the change out
  • remaining issues – jargon and “i can find everything in google” problems

Amanda:

  • spoke on making dynamic, page-based breadcrumbs on a website
  • did a study of common paths customers took to get to certain pages
  • they made something that constantly tells what paths customers are taking – very cool! They can narrow down to a single day if they want to
  • future directions – implement predictive track analysis – find out where people are getting lost dynamically, then have something po up that says “were you really looking for this?”

    I wonder if they could develop a suggestion module that more accurately can guess the title of the book they were looking for?
