2 Content of Delivery 1.Objectives & CDIO Compliance 2.Learning Theory & Implementation 3.Students’ Findings 4.Creation of Workspace 5.Video

3
3 Objectives -Active engagement to reflect on subject content -1 st hand experience in data collection -Sharpen research skills -Develop confidence for classroom sharing

4
4 Participants 51 first year students from -Diploma in Computer Engineering - Diploma in Information Communication Technology

5
5 CDIO Standard 6 & 8 - Structure learning space into class time periods - Lessons in the Media Viewing Room - Video for group reflection & peer review - Students embark on experiential learning

6
6 Learning Theory Theory of action/reflection learning (Dilworth,1998) L = P + Q + R L : Learn by doing P : Programmed Knowledge Q: Questioning R: Reflection

7
7 (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 Implementation

8
8 Active & Experiential Learning Group C & D Construct Stem-and- leaf Diagrams Group A & B Data Analysis using mean, median & mode Lecturer As Facilitator Interview library Users, Group Viewing & Reflection

9
9 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

10
10 Findings 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
11 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

12
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

16 Back-to-Back Stem-and-leaf diagram Compare 2 data sets Data Measures of Central Tendency Frequency Table are organized into Grouped Frequency Table are used to calculate ModeMedianMean Sensitive to NOT sensitive to Sensitive to Change in Frequency Extreme Values or Outliers

17
17 Which is the best representative of the data set: 1, 1, 2, 3, 3, 10 and 1? (a) mean(b) median(c) mode(d) all of them TomStemJane 2 113 2 5 622 5 1 1 133 4 5 x45 5 7 (a)How many tests did they each participate in? (b)If Tom ’ s highest score was 3 less than Jane ’ s highest score, find the value of x. (c) Which score occurred most often? Key: Tom - 2 | 1 rep 12 marks Jane - 2 | 5 rep 25 marks

18
18 I understand and am able to....YesNoNot sure (i)interpret and analyse stem-and-leaf diagram (ii)find the mean, median and mode from a set of values (iii)find the mean, median and mode from a frequency table (iv)calculate the mean and standard deviation for group data (v)distinguish the purpose and use of mean, median and mode Comments (if any)
