Theme: With technologies student solve problems differently.
Presentation by Zoltán Kovács, Hungary, at the 4th European Workshop on Mathematical & Science eContents; see abstract
More Details:
- case study based on GeoGebra; citing Pólya (for problem solving practice)
- speaker walked through a geometrical problem: “cut two congruent circles from a triangle such that their area were maximal.” pointing out the problem solving steps (path)
- presented various problems in GeoGebra
- evaluation: students were introduced in GeoGebra with easy exercises/ then were instructed how to use tools in the classroom; student played being teachers; essay on selected research paper (was is interesting for me); afterwards splitting students in 2 groups of 12 students; 45 minutes time to solve a geometric problem; first group with GeoGebra+pen&paper and second one with pen and paper only; only two solutions with GeoGebra (one of them correct); second group followed the analytic method (rather than geometric); first group used first GeoGebra and forgot about the pen+paper (even they were told to use pen+paper – this maybe a drawback/ danger in using technologies)
