There are three levels of GeoGebra Certification that you begin to reach as a result of this week's workshop. Everyone will leave this week with User Certification. Some of you may be able to complete everything needed for Expert Certification.

User Certification

GeoGebra Users have the skills to successfully use GeoGebra materials with students in their classrooms.

GeoGebra Users should demonstrate the following skills to be certified by a GeoGebra Institute.

Operation of GeoGebra

• Familiarity with available GeoGebra Views, geometric tools, as well as the use of basic commands.
• Ability to change the properties of objects in order to create appealing instructional materials.
• Use of GeoGebra to create ggb files, export static images and insert them into a word processing document, as well as to create interactive web pages, i.e., Dynamic Worksheets.
• Knowledge about the use of the GeoGebra Help document in order to find out about information about unfamiliar tools, commands, and features of the software.

GeoGebra for Teaching and Learning 

• Knowledge of the dynamic capabilities of GeoGebra, in particular of the potential of interconnected multiple and dynamic representations for mathematics teaching and learning.
• Use of GeoGebra as a demonstration and presentation tool with existing and  self‐made instructional materials (e.g. ggb‐files, Dynamic Worksheets).
• Selection and use of existing GeoGebra materials (e.g. ggb‐files, Dynamic Worksheets) from the GeoGebraWiki or other sources.
• Showing enough confidence with the use of GeoGebra to let students work with prepared GeoGebra materials (e.g. ggb‐files, Dynamic Worksheets).

Role in the GeoGebra User Community

• Ability to post questions on the GeoGebra User forum to extend one’s knowledge about the use of the software.

Expert Certification

GeoGebra Experts have the skills to create and share GeoGebra teaching materials, as well as support other educators in their schools or regions.

GeoGebra Experts should demonstrate the following skills in addition to those of GeoGebra Users to be certified by a GeoGebra Institute.

Operation of GeoGebra

• Familiarity with the use of algebraic expressions and commands in the Input Bar.
• Familiarity with the use of advanced features like animations, sequences, dynamic text, and conditional visibility.
• Using the Construction Protocol and other strategies to find out how an existing GeoGebra construction was created.
• Ability to create User Defined Tools and ability to customize the user interface of GeoGebra (e.g. Tool Bar).
• Familiarity with advanced options of Dynamic Worksheets (e.g. Advanced tab of the Dynamic Worksheet as Webpage export window). 

GeoGebra for Teaching and Learning

• Using GeoGebra as a tool for teaching and learning by creating constructions from scratch during classes.
• Ability to adapt existing ggb‐files and Dynamic Worksheets to the local curriculum and specific needs of students.
• Showing confidence in introducing students to GeoGebra and guiding them towards an independent use of GeoGebra while supporting discovery learning and mathematical experiments.

Role in the GeoGebra User Community

• Ability to answer questions on the GeoGebra User Forum and to provide guidance and support to colleagues.
• Ability to create and share innovative instructional materials with the GeoGebra community by using available means and websites (e.g. on the GeoGebraWiki).
• Actively seeking contact with other educators in order to collaborate and exchange knowledge and experiences about the use of GeoGebra.
• Ability to give workshops for GeoGebra novices in order to introduce them to the basic use of GeoGebra and familiarize them with methods of using the software to enhance teaching and learning with technology.
