Nov IT, Algebra & Teachers Ø How to promote the use of technology by teachers in algebra? Professional development w Many money has already been spend Research on teachers practises: w Problems? w Obstacles?
Nov IT as a tool for research Ø Collaborative learning E.g.: AMICO (Delozanne, Grugeon) Goal : w to make sense of algebraic expressions in arguing with different virtual companions a virtual mathematician
Nov Arguing with virtual agents Ø Problem: Are (x²+8x+12) and (x – 3)(x- 5) equivalent expressions? Ø Solution : Student : yes they are Companion 1: I disagree. If I take x = 0… Companion 2 : I disagree. By expanding… Mathematician : They are not equivalent because…
Nov Computers of the future Ø Collaborative learning with virtual and human agents Ø New computers: Beyond the desktop New input or display devices: w captors (e.g.: embodiment modeling, Arzarello) Augmented reality: computers embedded in familiar objects w Electronic paper Ø New classrooms or schooling organization
