Learning Theory
Theory of action/reflection learning
(Dilworth,1998)
L =P+Q+R
L : Learn by doing
P : Programmed Knowledge
Q: Questioning
R: Reflection

Implementation
(A) Most preferred library materials
e.g. Periodicals/DVDs and music CDs
(B) Most preferred library facilities
e.g. PC facilities/study facilities /loan facilities
(C) No. of hours male users spent weekly in library
(D) No. of hours female users spent weekly in
library

Findings by Group A & B
Most Preferred Library Materials - DVD
(entertaining)
- Followed by Music CDs & Periodicals
Most Preferred - Study facilities
(conducive for learning)
- Followed by PC & Loan Facilities
9
Findings by Group C & D
Male & Female Users share same usage pattern
- Spent average of 3 hours per week in the library
- Females go there to study
- Males go there during break times
- Findings similar to Group B
(study facilities as most preferred choice)
10
Creating Workspace for Learning
(Freeman, 2005) The library functioned as
an extension of the classroom for students
- engage in collaborative learning
- refine their critical thinking
11
Library was chosen:
• Provide workspace for experiential
learning & group sharing
• Ready stream of library users to
conduct face-to-face interviews
• Rich resources facilitate teaching &
learning
12
Conclusion
- innovative way of learning outside classroom
- experiential learning reinforce understanding
- heighten interest in learning statistics
- enhance confidence in social interaction
