A Brief Introduction of Mathematics Education Using GeoGebra In Korea Kyeong-Sik Choi Gyeonggi-Buk Science High School, Korea A Brief Introduction of Mathematics Education Using GeoGebra In Korea

Previous Researches of DGS in Korea About GSP Kang and Choi-Koh(1999) 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

Previous Researches of DGS in Korea About JavaMAL (DGS + LOGO) (http://www.javamath.com/class) Kim and Cho(2004) Functional definition Cho, Choi and Kim(2002) Algebraic bar model, dynamic geometry model, graph model x + y = 25 x – y = 5 For the students who don’t know variables

GeoGebra Projects in Korea Korean Translation Sep. 2008 ~ 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

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)

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

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.

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
