Black Boxes in Analytical Chemistry: University Students' Misconceptions of Instrumental Analysis
Carbo, Antonio Domenech; Adelantado, Jose Vicente Gimeno; Reig, Francisco Bosch
Online Submission, US-China Education Review v7 n7 p15-29 Jul 2010
Misconceptions of chemistry and chemical engineering university students concerning instrumental analysis have been established from coordinated tests, tutorial interviews and laboratory lessons. Misconceptions can be divided into: (1) formal, involving specific concepts and formulations within the general frame of chemistry; (2) operational/topical, dealing with specific capabilities, problems and operations in chemistry; (3) methodological, associated to peculiar methods of analytical chemistry and data treatment; and (4) social, regarding the relation of analytical data with the social frame. Such misconceptions define a non-structured view of analytical methods, procedures and protocols related with analytical instrumentation. Instruments are frequently viewed as an autonomous, error-free black box providing non-structured data with no need of calibration or control, whereas weak relationships are established between data and aims along the analytical process.
