IT, Algebra & Teachers • How to promote the use of technology by teachers in algebra? • Professional development • Many money has already been spend • Research on teachers practises: • Problems? • Obstacles?
IT as a tool for research • Collaborative learning E.g.: AMICO (Delozanne, Grugeon) • Goal : • to make sense of algebraic expressions in arguing with • different virtual companions • a virtual mathematician
Arguing with virtual agents • Problem: • Are (x²+8x+12) and (x – 3)(x- 5) equivalent expressions? • 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…
Computers of the future • Collaborative learning with virtual and human agents • New computers: Beyond the desktop • New input or display devices: • captors (e.g.: embodiment modeling, Arzarello) • Augmented reality: computers embedded in familiar objects • Electronic paper • New classrooms or schooling organization
