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

Findings by Group A & BFindings 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
10
Findings by Group C & DFindings by Group C & D
- Females go there to study
Male & Female Users share same usage pattern
- Males go there during break times
- Findings similar to Group B (study facilities as most preferred choice)
- Spent average of 3 hours per week in the library

Creating Workspace for LearningCreating Workspace for Learning
(Freeman, 2005) The library functioned as
an extension of the classroom for students
-engage in collaborative learning
- refine their critical thinking
12
• Ready stream of library users to conduct face-to-face interviews
• Rich resources facilitate teaching &learning
Library was chosen:
• Provide workspace for experiential learning & group sharing
13
ConclusionConclusion
- innovative way of learning outside classroom
- experiential learning reinforce
understanding
- heighten interest in learning statistics
- enhance confidence in social interaction
