In this paper, the development of an automatic assessor
is presented,
both in MATLAB and in Excel, for an analytical exercise. In particular,
the emulation of an interlaboratory exercise, using the analytical
determination of phosphorus in a dry detergent, carried out in the
laboratory by different groups of students, was selected as a case
of study. The automatic assessor was used in the e-learning environment
DOCTUS, which allows students to submit their results to a server
to receive back immediately their mark and an indication of their
possible mistakes. Using this approach enhances the learning experience
of the laboratory work of students. The experience described in this
article has been developed in the frame of the subject “Quality
Control in Analytical Laboratories” corresponding to the chemistry
degree at the University of Extremadura (Spain) along the academic
courses from 2017/2018 to 2021/2022. The impact of the implemented
tool on students’ academic performance has been also addressed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
