Reliability of several subject didactic assessment instruments.
The use of assessment instruments may help teachers monitor their own subject didactic effort in an effort to attain certain goals. In the light of the critical importance which subjects in the natural sciences (e.g. mathematics and physical science) have assumed in South Africa, research on assessment instruments has become of critical importance. However, the effectiveness of these measuring instruments has to be established beforehand. The aim here was to compare the SOM, LEMOSS(II) and LCH questionnaires in terms of reliability. The ultimate aim of the analysis is the use of these questionnaires to optimise learning competences, especially in mathematics, physical science and home economics. It was found that the three questionnaires discussed can be used with an acceptable degree of confidence for the measurement and optimisation of the subject-related learning competences of Grade 9 learners in the Tzaneen and Phalaborwa areas. Furthermore, there was a significant positive correlation between sufficient of the problem-solving strategies and better achievement in the subjects discussed.
