- ItemDescription and impact of a distance mathematics course for grade 10 to 12 teachers(AOSIS Publishing, 2007-06) Stols, Gerrit; Olivier, Alwyn; Grayson, DianeThis paper explores the impact of a one-year in-service distance education mathematics course that follows a problem-solving approach. The course aims to develop teachers’ mathematical thinking skills. Results show that the course improved the teachers’ confidence, problem-solving skills and teaching skills. Results also show that the course on mathematical thinking skills helps to improve teachers’ understanding of mathematics content.
- ItemThe potential of teacher development with Geometer’s Sketchpad(AOSIS Publishing, 2008-12) Stols, Gerrit; Mji, Andile; Wessels, DirkIn this paper we document the advantages of utilising technology to enhance teachers’ instructional activities. 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.
