Introduction
√ How Intel ISEF 2010 has brought joy to the little countryside home and brought hope to the disaster area
√ How math project has brought joy to math learning and research

Math Becomes Experimental
• Mathematics is regarded as a branch of theoretical science.
• Science project turns Mathematics into an experimental science.

Visual
• Pure mathematicians speak of the thrill of abstraction.
• Math project takes pride in making abstract concept visible and dynamic.

Don’t Spoil the Fun
• Three parts of a theorem: – “Given” – “To prove” – “Proof”
• Thousands of years: “Proof” the most precious.
• Dynamic Geometry : “To Prove” the most exciting.

Attention Span
• It is easy to deliver a math lecture making the audience sleep.
• When a mathematical proof is turned into an interactive game, people get addicted.

PowerPoint?
• PowerPoint makes interactive Q&A hard.
• Webpage links the minds to an unknown depth.

Principle of Duality
• Treat a constant as a variable• Treat a variable as a constant

Old Wine…
• Conventional Wisdom: Don’t discover a theorem unless it has at least three applications.
• Math Project: Don’t start a mathematical experiment unless there are at least three different ways to do so with the computer.

Symbols
• Appropriate math symbols make presentation clean.
• Redundant symbols make presentation ugly.
![Page 11: Professional development for STEM Educators The Joy of the Math Project Jen-chung Chuan National Tsing Hua University Hsinchu, Taiwan Aug, 2010](https://reader035.vdocument.in/reader035/viewer/2022062407/56649d0a5503460f949dd4f3/html5/thumbnails/11.jpg)
Index
• Avoid using indices.
• Verbal expression reflects a sharper mind.

Mathematical Maturity
• Mathematical maturity - best propaganda for any math project.
• References speak such quality loud and clear.
![Page 13: Professional development for STEM Educators The Joy of the Math Project Jen-chung Chuan National Tsing Hua University Hsinchu, Taiwan Aug, 2010](https://reader035.vdocument.in/reader035/viewer/2022062407/56649d0a5503460f949dd4f3/html5/thumbnails/13.jpg)
Ego
• A mathematician’s ego is found in the scratchpad.
• He is willing to fight to keep it confidential.
• Art of a science project : transform it beyond recognition.
![Page 14: Professional development for STEM Educators The Joy of the Math Project Jen-chung Chuan National Tsing Hua University Hsinchu, Taiwan Aug, 2010](https://reader035.vdocument.in/reader035/viewer/2022062407/56649d0a5503460f949dd4f3/html5/thumbnails/14.jpg)
Efficiency
• Amount of time for presentation- limited • The quality of judging is gauged
by the efficiency of the presentation.
• Ambiguity: worst sin • Just imagine the amount of time saved
without having to clarify definitions!

White Board• Tools for scientific presentation - far from
ideal. • In math seminars chalk is used. • Pace and Flow of Ideas can hardly be
simulated with computer.
•Bring a white board.

Magic Show
• People love magic shows.
• Extract the mathmagic ingredient of the project and start seducing the audience.
![Page 17: Professional development for STEM Educators The Joy of the Math Project Jen-chung Chuan National Tsing Hua University Hsinchu, Taiwan Aug, 2010](https://reader035.vdocument.in/reader035/viewer/2022062407/56649d0a5503460f949dd4f3/html5/thumbnails/17.jpg)
Insight
• Mathematical methods?• Meaningful in higher math?• Physical significance?• Visualized? • Simulation with a computer? • Accessible to high school student?• Accessible to primary school student?
![Page 18: Professional development for STEM Educators The Joy of the Math Project Jen-chung Chuan National Tsing Hua University Hsinchu, Taiwan Aug, 2010](https://reader035.vdocument.in/reader035/viewer/2022062407/56649d0a5503460f949dd4f3/html5/thumbnails/18.jpg)
Reality Check
• Have you given your presentation to your parents?
• Do they understand it?
![Page 19: Professional development for STEM Educators The Joy of the Math Project Jen-chung Chuan National Tsing Hua University Hsinchu, Taiwan Aug, 2010](https://reader035.vdocument.in/reader035/viewer/2022062407/56649d0a5503460f949dd4f3/html5/thumbnails/19.jpg)
Another Reality Check
• What have you learnt from the project?
