In particular we showcase the potential and impact that the use of Geometer¡¯s Sketchpad may have on the teaching and learning of geometry at school. A series of five, two-hour teacher development workshops in which Geometer¡¯s Sketchpad was used were attended by 12 Grade 11 and 12 teachers. The findings revealed that teachers had a better understanding of the same geometry that they initially disliked. This finding was supported by a quantitative analysis which showed a positive change in the understanding of and beliefs about geometry from when the teachers started to the end of the workshops. %K Geometer¡¯s Sketchpad %U http://www.pythagoras.org.za/index.php/pythagoras/article/view/63
