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

  2. 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

  3. Previous Researches of DGS in Korea x + y = 25 x – y = 5 For the students who don’t know variables • 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

  4. 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

  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
