D.Phil. (Education) / The study-group in this study focus on the education students of the Rand Afrikaans University (RAU) from 1988-1990. All these students completed the diagnostic testing program of RAU as well as the practical course in didactics. The practical mark in didactics were used to distribute the students into three research sub-groups. This mark reflected the students' didactical skills in a simulated classroom situation. The diagnostic data which was utilised to compile a profile of the study-group consisted of tests for intelligence, aptitude, adaptation, personality and study habits, as well as relevant biographical data. The students' academic achievement in matric was determined by the M-score. The three sub-groups were determined by calculating the average of the groups' practical mark and cut-off points of half a standard deviation on either side of the average. This presupposed a less superior didactical group (Group A) versus a superior didactical group (Group B), utilized for statistical purposes. The calculations did not include the middle group. The entire discussion of the career process selection was based on Super's career choice model. This was done to determine the main contributory factors in selecting teaching as a career. A literature study was made of the teacher and teaching as a career, followed by a discussion of the Importance of the attributes of the excellent teacher, which included more than just good academic achievement. Teaching as a career was also discussed, emphasizing a temporary difference between the practical and theoretical aspects of t118 didactics course, in order to identify which specific attributes contributed to the success in the practical component of the course. A discussion based on literature was done to determine the various psychological tests and questionnaires which were utilized in this study, namely NSGT, SAT, 16-PF, PHSF, 19-FII, SSHAas well as supportive biographical data. The aim of this study was to determine certain psychological aspects which contributed to the success in the practical components of a course in didactics. A career choice is usually made during the late adolescence. In discussing a career choice model, Super (1990) explains various determinants which influence career choice including the geographical origin, personality and contributory aspects of an individual's personality...

The present study sets out to evaluate the effectiveness of a dynamic approach to aptitude testing. It was proposed that it is not always appropriate to use conventional aptitude tests to predict future academic success in the South African context. The study posited the belief that an alternative testing format could be facilitated by using a test-train-test procedure within a learning potential paradigm. The learning potential paradigm as formulated through Vygotskian and Feuersteinian theory is operationalised in the form of a Newtest Battery. The Newtest procedure is in direct contrast to traditional approaches to aptitude testing. The latter approaches both implicitly and explicitly adopt a static view of ability, whereas the Newtest approach focuses on the learning potential of the testee, as well as consequent performance. However, the assessment of learning potential poses problems of its own. Modifications were introduced to ensure that the Newtest format is both appropriate and psychometrically defensible. The construction and evaluation of the Newtest Battery is described. A sample of both advantaged and disadvantaged students were tested on a battery of traditional aptitude tests. This group of students was contrasted with another sample of both advantaged and disadvantaged students who undertook the Newtest Battery in the modified dynamic testing format. The traditional measures of aptitude were found to be invalid predictors of university success. Matric results showed a relationship with academic success for both groups. The Newtest measures enhanced the prediction of academic success for both advantaged and disadvantaged students. The Deductive Reasoning dynamic measure was found to be a valid predictor of university success for the disadvantaged students. The results thus successfully extend the learning potential paradigm into the realm of group aptitude testing. The validity of traditional aptitude test measures has been brought into question by the findings of the study. The study points the way forward to a more equitable and relevant aptitude testing procedure. Finally, it was shown that the testing environment forms part of the socio-educational context. Personnel involved in the administration of aptitude tests are given guidelines \vi th the aim of equalising the test process. / Psychology of Education / D. Ed. (Psychology of Education)
