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

11

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
