Die doel van hierdie studie was om ’n bestaande, maar uiters verouderde belangstellingsvraelys
(Rothwell-Miller-belangstellingsvraelys [RMBV]) aan te pas. In die eerste fase is vier provinsies
by wyse van doelsteekproeftrekking geselekteer: een stedelik en drie plattelands of
semiplattelands. In fase twee is ’n steekproef van 518 Graad 11-leerders met behulp van
doelsteekproeftrekking geselekteer (gemiddelde ouderdom [x] manlik = 17.52 jaar, vroulik =
17.39 jaar; standaardafwyking [s] manlik = 0.97 jaar, vroulik = 0.93) in agt skole, verdeel
volgens onderrigtaal (Afrikaans/Engels) en streek (stedelik/plattelands/semiplattelands).
Statistiese analises het die vasstelling van betroubaarheid ingesluit by wyse van die berekening
van Cronbach se α, asook die halfverdelingsmetode. Die data is verder geanaliseer by wyse
van statistiese tegnieke soos t-toetse, ANOVA, asook Tukey se Honest Significant Differencetoets
(HSD). Die resultate word bespreek en die gevolgtrekking word gemaak dat hoewel die
aangepaste vraelys tot ’n nuttige instrument vir gebruik in Suid-Afrika ontwikkel kan word,
verdere navorsing eers nodig is.
The aim of this
study was to adapt an existing but extremely dated interest questionnaire, the Rothwell-
Miller Interest Blank (RMIB). In the first phase, four provinces were selected purposively: one
urban and three rural or semirural. Secondly, a purposeful sample of 518 Grade 11 learners in
eight schools was selected (mean age [x] Male = 17.52 years, Female = 17.39 years; standard
deviation[s] Male = 0.97 years, female = 0.93), divided according to medium of instruction
(Afrikaans/English) and area (urban/rural/semirural area). Statistical analyses included
determining of reliability by calculating Cronbach’s α and the split-half reliability. The data
was further analysed by means of statistical techniques including t-test, ANOVA and Tukey’s
HSD. Results are discussed and the study concludes that although the adapted questionnaire
could be a valuable instrument for use in South Africa, further research is required.
