Misconceptions and metaconceptions in instrumental analysis

Normative science models are accompanied by a number of metaconceptions dealing with the foundations, methods and applications of the fundamental science formulations whose presence in the science curricula is needed. In the case of instrumental analytical chemistry, metaconceptions include from analytical properties to operational concepts. Student’s misconceptions concerning instrumental methods, procedures and protocols have been established from coordinated tests and tutorial interviews during laboratory lessons. Results for chemical engineering university students indicate that most misconceptions in instrumental analysis can be associated to a non-structured view of concepts and methods in turn related with metaconceptions in analytical chemistry.
