Characteristics of Mathematics
|
- Takes long time to build up basics
– High school curriculum (ancient to 17th century)
– Undergraduate (18th to 19th century)
– Post-graduate (20th century and recent)
|
- Requires two extremes of abilities
– Calculations: routine but easily rewarding
– Imagination: attractive but abstract
|
- Attitude
– Logical and rigorous
|

Common Learning Mode
|
- Understanding of established concepts
– Thorough study of literature
– Do or re-do similar or related problems
– Massive amount of calculation tasks
|
- Presentation of known materials
– Demonstrate of exercise solution
– Seminar presentation
– Survey or expository writing
|
- Mostly work on given texts or articles

Usual Learning Rewards
|
- Achievement
– A tricky problem is conquered
– A clever method is found
– A hard text is understood
– Peer admiration
|
- Knowledge
– Building a jigsaw puzzle
– Seeing the elegance and coherence
|
- Only a little from joy of creation

Normal Assessment Goals
|
- Understanding of established concepts
– Recognition of key concepts
– Pinpointing major arguments
– Handling complex patterns and procedures
|
- Presentation of known materials
– Logically written calculations
– Deductive analysis

Disadvantage
|
- Long duration of assimilation
– Usually up to finishing an MPhil
|
- Difficult to raise questions
– A culture of taste: simple and important
– Aim of questions is usually misdirected
|
- Narrow margin for solutions
– Strict format
|
- Consequence: research only at PhD level

Course Structure
|
- A collection of problems
– Of 1st year undergraduate level
– With solution
|
- 3 to 4 groups of 3 students
– Formed with teacher coordination
|
- Framework
– From given problem to their own problems
– Enjoy the fail attempts to solve them
– Communicate with and assess each other
|
|
>>Top
|
|
Progression
|
- Each group select a problem (1 week)
- Give a brief introduction (1 week)
- Explain the given solution (2 weeks)
- Formulate their own problems (3 weeks)
– Outline their problems to others
- Observations and predictions (2 weeks)
– May reformulate the problems
- Present all their works and results (3 weeks)

Roles
|
-- Teacher Roles
|
- Problems compilation
- Encourage
– From very beginning
- Guidance
- Encourage
– Especially when students are stuck
- Refrain from teaching
– “I don’t know” is a good answer
|
--Peer Roles
|
- Talk to the audience
- Listen to unfamiliar familiarity
- Discuss and work with group-mates
- Assess own group
– Assess group-mates with a taste of self-assess
- Assess other groups
– On a few domains including presentation
– Free comments

Existing Characteristics
|
- Understanding of established concepts
– Study the selected problem and solution
– Added: acquired through discovery
|
- Presentation of known materials
– Several levels of exposition and report
– Not necessarily deductive
|
- Exactitude
– The ultimate attitude is still there
|
|
>>Top
|
|
Added Characteristics
|
- Detailed + Skeletal Understanding
– Own study + others’ work
|
- Accept ill-stated problems
– Clarify through reformulation
|
- Rough ideas, wild guess, and reasoning
– To give reasons for unfounded ideas is helpful
– Enhance imagination and creativity
|
- Partial result and unfinished work
|
|

|
|
Peer / Self Assessment
|
- Tend to be lenient
– Exception: self-reflection
|
- Consistent
– Among students
– With teacher’s assessment
– Slight deviation on knowledge domain |
- Appreciative
– Most valuable
|
|

|
|
Conclusions
|
- Still far from research
– Problems are too elementary
– Involved too less background search
– Narrow scope, restricted ideas
|
- Deconstruct and construct
– More accepting attitude favors exploration
|
- Peer Assessment
– Establish values more than a grading tool
