• Objective
• success in finding the correct answer
• information seeking behaviours
• -to apply Bilals Web Traversal Measure

24
 

• Method
• Two study groups
• 1- Middle school students (25 students)
• 2- Graduate students (12 students)

25
 

• search task
• how long do alligators live in the wild and how
  long in captivity?

• Web Traversal Measure
• Weight Assigned to every web move a user makes
• Traversal Every moves like searching, browsing,
  screen scrolling, backtracking, search looping.

27
Web Traversal Measure

• Effectiveness Amount of effort a user makes to
  locate a target page
• Efficiency Weight of relevant moves a user makes
  out of total traversal moves
• 
  
  
  
  

28
 

• 1 - Relevant
• 0.5 - Semi-relevant
• 0 - Irrelevant

• Procedure
• 30 minutes given to each student
• Lotus screen cam (software package that records
  and replays online activities in web browsers)
• Students documented their experiences and
  feelings during searching

• Results
• -Graduate students were more succesful in finding
  correct answers
• -Mean number of moves children made was 49 as
  opposed to 20 by graduates.
