• ### Geogebra intro

1. 1. Dynamic mathematics with Geogebra
2. 2. What is GeoGebra?  Dynamic Mathematics Software  For Learning and Teaching in Schools  Geometry, Algebra and Calculus  Freely available from www.geogebra.org
3. 3. GeoGebra = Geometry + Algebra Algebra Window Geometry & Graphics Window
4. 4. GeoGebra as a Pedagogical Tool  Presentation Tool dynamic visualizations  Modeling Tool dynamic constructions  Authoring Tool interactive online material
5. 5. Examples of Using GeoGebra  Visualizing students can “see” abstract concepts  Representations students can make connections  Experiments students can discover mathematics
6. 6. Visualizing Parameters
7. 7. Visualizing Movement
8. 8. Examples of Using GeoGebra  Visualizing students can “see” abstract concepts  Representations students can make connections  Experiments students can discover mathematics
9. 9. Multiple Representations  GeoGebra: Bidirectional Connection Symbolic ⇔ Graphics  Examples – Coordinates ⇔ Point in Coordinate System – Circle‘s Equation ⇔ Circle drawn in Coordinate System – Function‘s Equation ⇔ Graph of Function
10. 10. Representations: Sketch & Graph
11. 11. Unexpected Discoveries
12. 12. Examples of Using GeoGebra  Visualizing students can “see” abstract concepts  Representations students can make connections  Experiments students can discover mathematics
13. 13. Experiments: What happens when..?
14. 14. Experiments: Approximation
15. 15. Educational Principles  Student Activity  Modeling  Multiple Representations  Experimental and Guided Discovery Learning – Great to show you everything but better off discovering yourselves!
16. 16. Hands-on activities   ... of this module you should: Know more about Geogebra.  Have constructed a worksheet and succeeded in posting it online, adding it to your journal in BLACKBOARD. Didactics will follow in January. Concretely, your journal, should have:  An uploaded geogebra worksheet.  A 300 word evaluation of the strengths and weaknesses of Geogebra for teaching mathematics.
