Aanleg as determinant van studieprestasie in ingenieurswese

M.Ed. (Tertiary and Adult Education)This empirical study forms part of a team research project which was spearheaded by the Bureau of University Education at the Rand Afrikaans University. The aim of this study was to establish whether significant differences between the aptitudes of succesfull and non-succesfull freshman engineering students could be determined. This study consists mainly of two parts. Firstly, a literature study discussing the concepts aptitude and aptitude testing was undertaken. Secondly, an empirical study to establish differences in various aptitudes of the above-mentioned student groups was undertaken. According to the literature study, aptitude can be seen as a combination of factors which enables an individual to achieve a certain level of performance or to develop a certain skill with the necessary training. From the literature study it is apparent that aptitude is inherited, and also influenced by environmental factors. In early childhood it varies considerably but stabilizes in later years. Although slight similarities between aptitude and intelligence exist, a very clear distinction can be drawn. Differences between the aptitude patterns of men and women also appear. In the empirical study a random sample (N=388) was taken from the 1989 - 1991 freshman engineering students of the Rand Afrikaans University. The results of the Senior Aptitude Test (SAT) of the Human Sciences Research Council (HSRC) were used to indicate d ifferences between the above-mentioned student groups. Students t-test was used to establish significant differences between the two groups. The data which was already available, was processed by means of the BMDP-3D computer programme. Significant differences between the two groups were identified, proving/indicating that aptitude should be taken into account during the process of student selection for the engineering course
