Applications of quality assurance in an educational chemistry laboratory

I Pumure

Abstract


It is a well-known fact that, the over all student performance in practical work is a function of a closely interwoven ternary system that includes the teacher, the laboratory technician and the student. The contribution of these people towards the success of a students starts from experimental design and reagent preparation stages. The implementation of a quality assurance system in a Chemistry laboratory reduces shortcomings associated with student failure, which includes unpreparedness, mismanagement of time, lack of practical work techniques, improper data processing and presentation. This can be instituted, in part, by the application of cheap and reliable reference materials made by the teachers. A collaborative proficiency-testing group involving a number of Chemistry teachers and peers can be set to select suitable candidates for reference materials. A quality assurance system installs teacher confidence that the Chemistry laboratory is performing effectively in training students.
