A Thesis submitted to the Faculty of Science
University of the Witwatersrand, Johannesburg,
for the Degree of Doctor of Philosophy. / Student and pupil difficulties relating to the qualitative
interpretation of microscopic processes which take place in
operating electrochemical cells were determined. The subjects
were studying electrochemistry at either high school, college
of education or University. The investigation followed a
stage process which involved the identification of
misconceptions, further inquiry into the nature and possible
causes of these as well as the development and evaluation of
a teaching method aimed at alleviating the identified
problems.
The interview and the pencil and paper methods were employed
to elicit the misunderstandings and simple experiments
provided the focus of discussion. From the relatively broad
base of the initial stages in which open-ended questions were
used, the problem areas narrowed progressively as the stud
difficulties became clarified. The tape recorded interviews
as well as the responses from the pencil and paper test were
analysed for apparent misconceptions. Four areas emerged as
problematic among the majority of the subjects. (Abbreviation abstract) / Andrew Chakane 2019
