Learning Theory

Theory of action/reflection learning (Dilworth,1998)

L = P + Q + R

L : Learn by doing P : Programmed Knowledge Q: Questioning R: Reflection 6

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 7

Group A & B Data Analysis using mean, median & mode Lecturer As Facilitator Active & Experiential Learning Group C & D Construct Stem-and leaf Diagrams Interview library Users, Group Viewing & Reflection

8

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 13

Mean

Sensitive to Change in Frequency

Median Mode

NOT sensitive to Sensitive to Extreme Values or Outliers 16

Which is the best representative of the data set: 1, 1, 2, 3, 3, 10 and 1?
