talented students while solving aqueous euilibrium problems.
asked to think aloud while solving problems and their
analyzed to describe their problem-solving behaviors and
factors affecting success of problem-solving. Three major
clusions are summarized as follows: (1)Problem-solving behavior
Four subjects'' performance was characterized by the nature
cessful problem solvers and novices. The former includedl
representation, perceiving the problems as tasks deservings
and reasoning,using good heuristics, and constructing a
solving conceptualization of domain specific knowledge.
(2)Specific concepts and skills for problem-solving of
aqueous All subjects can use the related concepts and skills
to, but some possessed chemical misconceptions. (3)Factors
affecting success of problem-solving The results indicated
that those factors affecting success solving included
appropriate problem representation,the amount chemical content
knowledge, using the algorithm correctly,ma- tical skills,
effective strategy,checking of the inconsistecy reasoning and
quantitative calculation and the difficulty of
