  1. Cabri 3D:an environment for creative mathematical design Kate Mackrell, June 2007

  2. In the spirit of Logo • Dimensions of purpose and utility (Ainley+Pratt, 2006) • Examples – GSP DGYL project, work of students of Sipus, Gusic and Mladinic at this conference

  3. Purpose, Utility and 3D DGS • Need to engage with mathematics to create satisfying objects • Examples from my own exploration

  4. Aim of research • Overall projects that engage learners + develop their mathematics • Design of materials which enable students to engage effectively with Cabri 3D

  5. Context • Grade 7 and 8 students in programme for academically able • Motivated students • Good facilities • Relaxed curriculum

  6. Projects • Club May/June 2006 • Gr 8 dream house Oct/Nov 2006 • Gr 7 transformations Feb 2007 • Gr 7 polyhedra May 2007 • Gr 8 animation June 2007

  7. Interventions • Teacher – led • Handouts • Flash Demos • Website • Replay Construction files

  8. Findings All students able to use Cabri to construct complex objects Evidence of creative use of mathematics in pursuit of own goals. Flash demos and replay construction files are the best learning materials (so far!)

  9. Issues • What mathematics are students engaging with? Does this require the naming of new mathematics? • How can I fine-tune the balance between giving too much and giving too little?
