Expertise & spatial reasoning in advanced scientific problem solving
نویسندگان
چکیده
Visualization and other forms of spatial cognition are considered fundamental to learning and problem solving in science. This assumption is especially prevalent in organic chemistry where imagistic reasoning is considered to be a primary cognitive activity. While previous research has shown that students are aware of several analytical heuristics and imagistic strategies for problem solving, there have been no studies exploring how experts in organic chemistry approach problem solving. Here, we identify problem solving strategies employed by ten chemistry experts to solve undergraduate organic chemistry assessment tasks. Our findings suggest that experts employ a range of imagistic and analytical strategies for reasoning about spatial information and prefer, on average, to use analytical strategies.

متن کاملIntegrating derivational analogy into a general problem solving architecture∗
True expertise requires knowledge-intensive reasoning as a primary mental activity and a fallback to general problem solving in order to bridge gaps in the domain knowledge or to handle otherwise unexpected situations. This paper unites derivational analogy, a form of case-based reconstructive reasoning driven by rich episodic knowledge, with a general problem solving and planning architecture....

متن کاملHow Can Expertise be Defined? Implications of Research From Cognitive Psychology
In Cognitive Psychology, the experimental study of expertise involves applying concepts and methods from a number of areas: problem solving, learning, and ergonomics, to name just a few. The study of expertise provides a focus for basic research on many phenomena of cognition, such as memory limitations and reasoning biases. It also provides a focus for discussion of issues in cognitive theory,...
متن کاملExperience, Introspection, and Expertise: Learning to Reene the Case-based Reasoning Process* Experience, Introspection, and Expertise: Learning to Reene the Case-based Reasoning Process
The case-based reasoning paradigm models how reuse of stored experiences contributes to expertise. In a case-based problem-solver, new problems are solved by retrieving stored information about previous problem-solving episodes and adapting it to suggest solutions to the new problems. The results are then themselves added to the reasoner's memory in new cases for future use. Despite this emphas...
