Let’s start …
What is the value of the “Golden Ratio” ?
It is “1.618033989…”.
When did we learn this number ?
Why is it important ?

Effectiveness
What is Effective Learning ?How much do you remember what you have learned for your latest examination ?
Surface learning perhaps mainly by rote memorization
Short Term Memory
What is Effective Learning ?Knowledge stored in our
Long Term Memory
1. solving problems in different situations2. breaking problems down into small parts
etc…………….
Motivation for LearningA) Extrinsic motives
– To pass a test / examination – To complete an assignment
B) Intrinsic motives– To add value to oneself– For the sake of interest
How to set the right motivation ? A) Set Goal
– Where are you going ?– Why do you want to get there ?
B) Assess Outcomes– Are you making progress ?– How do you know when you are
there ?
Learning Outcomes
Bloom’s Taxonomy on Learning Outcomes
• Knowledge• Comprehension• Application• Analysis• Synthesis• Evaluation
Problem-Based Learning• Not only a student group project• Setup a mechanism to maximize
interactions among– Students– Facilitators– Learning materials (e.g., textbooks)– Experts in the world
• Facilitators and students are learners
Eight Tasks in PBL
Task 1– Explore the problem– Create hypotheses– Identify issues– Elaborate
Task 2– Try to solve the problem with what you
currently know
Eight Tasks in PBL
Task 3– Identify what you do not know
Task 4As a group
– Prioritize your learning needs– Set learning goals and objectives– Allocate resources– Identify tasks for each member
Eight Tasks in PBL
Task 5– Individual self-study and preparation
Task 6– Return to the group– Share the new knowledge effectively so
that the entire group learns the information
Eight Tasks in PBL
Task 7– Apply knowledge to solve the problem
Task 8– Assess the new knowledge, the problem
solution and effectiveness of the process used– Reflect on particular work and that of the group
Implementation
Four major steps– Exploring meeting [120 minutes]– Preparing meeting [60 minutes]– Sharing meeting [120 minutes]– Assessing meeting [60 minutes]
Step 1 - Exploring meeting1. Share weekly schedules and reflective
journals2. Role allocation (chairperson & secretary) 3. Perform PBL Task 14. Discuss and finalize the learning contract
with the facilitator
Sample
Step 2 - Preparing meeting1. Put together information
collected2. Decide if more information
should be collected3. Prepare for the sharing/teaching
meeting
Sample
Step 3 - Sharing meeting• Preparation for the presentation• Perform PBL Task 6 to 8
Sample
Step 4 - Assessing meeting• Perform self and small group
assessment• Put together the final draft report
Sample

Steps
Activity
1
Test students’ background knowledge Understand their expectationsIntroduce PBL method to the students
2 Give feedback on the test to the students
3 Perform the case study and the four meetings
4 Test and give feedback to the students

Purpose of PBL
Is it for teaching a subject ?
No, it is much more than that.
It is for enhancing learning attitude and process skills (e.g. information skills, team skills)
Student Feedback• Power Electronics is an interesting topic, and the teaching
method is really different from other EE courses, it is totally fresh to me. It offers us a chance to learn independently and prepare for the presentation. It's a good experience
• Firstly, I would like to say thank you for your teaching and kind help for this subject and I've got a good result in the exam. I think PBL is a good learning method for understanding the subject in depth. It stimulates students’ interest and encourages students to learn by himself/herself. Unfortunately, time is not enough for us to further understanding the matter, it is the main disadvantage of this course or may be it is due to the constraint of the current education system.A good teacher is also important for PBL, I think a good teacher can give a suitable response to student and boost the learning process and you have done a good job. Finally, I would like to express my thanks to your contribution.
Factors Affecting Learning Effectiveness
1. Prior knowledge 2. Skills3. Timely feedback / expert
guidance4. Self – initiative 5. Motivation / attitude
