Regular polyhedron and its development figures
Kim(2002)
Materials according to Polya’s problem-solving steps
1. understading the problem
2. select a stratagy
3. carry out the stratagy
4. evaluate the results

x – y = 5
For the students who don’t know variables

4. GeoGebra Projects in Korea
Korean Translation
Sep ~ Apr. 2009
Institute for Gifted Students
Writing materials for gifted students
Not teaching simple math concepts
But exploring and/or creating math concepts and formula by students

5. GeoGebra Projects in Korea
Institute for Gifted Students (7th grade)
Topic : “Let’s make a model of Solar System”
Data : from Wikipedia(Korean)
Orbital period , aphelion (as the radius of a circle)
Formula
Planet_algle = 360/{orbital period} * day(slider)

6. GeoGebra in the Mathematics classroom
Topic
Point and Coordinate
Time and Place
May 14, 2009 / Computer lab
Example
Find the trace for the point of same distance from the point A and B

7. GeoGebra in the Mathematics classroom
Teacher’s opinions
GeoGebra in mathematics class might…
Need time for the students to be familiar with GeoGebra
Have the constraint of selecting math problems for class to be suitable for GeoGebra (→ we need a new curriculum for learning math using computer, GeoGebra)
Be an attraction to the students from solving math problem to using GeoGebra
Students feedback
It was a very interesting experience.

8. Constitution of GeoGebra’s Communities on the Internet Environment in Korea
Naver Vs. Google In Korea ?
In 2003, Naver : 73% , Google : 1.3%
Isolated from the world-wide environment
A big intranet which has very good hardware
Naver café (a community of Naver)
Temporary solution
Naver → GeoGebra forum, wiki
