Based on information gained in an interview with a 12-year-old girl in grade seven, a rational reconstruction of the student's problem-solving strategy is proposed and compared with the strategies normally prescribed in contemporary school mathematics textbooks. (Author/CHC)

Investigates the relative contribution of two main components often used in the instruction of arithmetic and word-problem solving to first-grade children and children with learning problems: external representation with manipulatives and formal mathematical representation with number sequences. Four computer-aided treatments were developed along…

Describes self-regulatory processes that promote achievement in the basic skills of reading (clarifying purpose, understanding meanings, drawing inferences, looking for relationships, reformulating text) and mathematical problem solving (clarifying problem goals, understanding concepts, applying knowledge, monitoring progress). Experiences in…

Presents thinking-aloud protocols from secondary pupils solving arithmetic story and geometrical problems and analyzes their protocols by using interpretation models founded on a general problem-solving model. A word problem solving simulation is also used to further explicate processes pupils use to solve mathematical tasks. (Author/MBR)
