Operativity and the superordinate categorization of artifacts

Article Abstract:

A study conducted anmong first graders showed that children in the concrete-operational stage perform significantly better than their pre-operational counterparts in superordinate categorization tasks. However, operativity is important, not in the acquisition but in the utilization of superordinate knowledge. It functions by removing the person's focus from similarities which may hinder the construction of semantic relations. It may also enable the child to recognize the prime importance of taxonomic organization over other factors.

The development of proof construction in middle childhood

Article Abstract:

Researchers gave problem-solving tasks involving hidden-figure problems and a modified version of the game Mastermind to children aged 7-12 years. The findings supported J. Piaget's claims for steady development in proof construction during middle childhood, and for the emergence of an understanding of necessity and sufficiency during this period. However, performance in the hidden-figure tasks did not support Piaget's claim that an understanding of necessity precedes an understanding of sufficiency.

Proof construction: adolescent development from inductive to deductive problem-solving strategies

Article Abstract:

A study, wherein 100 adolescents responded to the problem-solving proof task and the reasoning competence selection task, validated the presence of cognitive developmental progression from an inductive to a deductive approach in their construction of logical proofs in problem-solving. This development is directly correlated to the levels of formal reasoning competence in the subjects.
