Prototypes: Brakes or Levers in Learning the Function Concept? The Role of Computer Tools.
Schwarz, Baruch B.; Hershkowitz, Rina
Journal for Research in Mathematics Education, v30 n4 p362-89 Jul 1999
Characterizes students' function-concept images that arise in interactive environments based on multirepresentational software. Shows that students (a) often use prototypic functions (linear and quadratic) but do not consider them exclusive; (b) use prototypes as levers to handle a variety of other examples; (c) articulate justifications often accounting for context; and (d) understand functional attributes. Contains 32 references. (Author/ASK)
