This study, called the Chemsa study, set out to determine: (i) the course aims of teachers of matriculation chemistry, (ii) how well these are reflected in and facilitated by the course syllabus, (iii) the influences of the examination on teaching practices and outcomes, (iv) how well the teachers' nonexamination aims were being achieved. Literature studies were carried out to compare: (i) the present and likely future examination practices in South Australia with those of other States of Australia and places overseas (ii) the aims of teachers involved in the Chemsa study with those considered by science educators to be desirable for this type of course. Investigations were carried out to discover whether there were absolute differences in standards of performance of candidates in the matriculation chemistry examinations of 1975, 1976 and 1977. The evidence produced was not conclusive, but gave rise to further questions. Conclusions have been drawn regarding the success of the chemistry course and teachers in promoting various outcomes.
