GeoGebra Pre-ATCM Conference 2012


Our Pre-ATCM Conference offers a good opportunity for the GeoGebra Community to meet colleagues from all around the world. Also, we can involve many colleagues and teachers from Thailand and other Asian countries.

Dates & Location

Structure and Agenda


There will be 3 keynote presentations highlighting important issues in both software and community developments (20min+10min questions). We welcome submissions for short presentations about interesting applications of GeoGebra, research and local community activities, these presentations can be 15min + 5min due to the shortage of time. Posters can be also presented.

  • Zsolt Lavicza, University of Cambridge, UK: GeoGebra Community and STEM Education

GeoGebra, a free, open-source, dynamic mathematics software, is rapidly gaining popularity in the teaching and learning of mathematics around the world. Currently, GeoGebra is translated to 62 languages, used in 190 countries, and downloaded by approximately 500,000 users in each month, and clearly making an impact on mathematics education in most countries. This increased use compelled the establishment of the International GeoGebra Institute (IGI) that serves as a virtual organization to support local GeoGebra initiatives and institutes. There are already 130 institutes in 85 countries, which pursue training and support of teachers, develop teaching materials, and carry out research projects. In this talk, I will outline the directions of GeoGebra software development, its extension to STEM subjects, activities of its community, and the work of GeoGebra Institutes.

Statistics is the most practical branch of mathematics since it is widely used in various sectors. Our research and others show evidences that many students held different misconceptions in statistics indicating they are weak in statistical reasoning (SR). Neglecting this problem will definitely impede students’ learning of statistics and curtail their enthusiasm if the problem is not overcome. A technology-based SR activity and a technology-based SR assessment tool were developed to promote SR ability and address learners' misconceptions. These instruments are based on SR framework proposed by Garfield (2002) and Jones et.al. (2000). The descriptors of SR framework are established across four key constructs with each construct divided into three subprocesses. The four major constructs are describing datas, organizing and reducing datas, representing datas, analyzing and interpreting data. The dynamic spreadsheet of GeoGebra software is used in technology-based SR activity as well as in technology-based SR assessment tool. Both tools were validated and rated by experts in statistics and then were tested on students through empirical research. We will discuss the design and development stage as well as to share our GeoGebra activities. This product not only introduce new way of looking at statistics but it will transform the way we learn, teach and assess statistics.

This presentation introduces the recent work of GeoGebra Institute of Hong Kong on teacher training, resources development and collaborative studies. I will present how we develop GeoGebra tasks to cater for the learning needs identified in our system assessments and collaborative studies through the fostering of visualization and reasoning in GeoGebra. The presentation will be illustrated by some resources in our depository on the topics quadrilaterals, multiplication and division of fractions, and the concept of slope.
