Assessment centres : a comparison of trait ratings and task ratings for predicting managerial performance / Taksentrums : 'n vergelyking van trekstellings en taakstellings in die voorspelling van bestuursprestasie

Heindl, Werner Andreas 06 1900 (has links)
Summaries in Afrikaans and English / In teenstelling met die takseersentrumteorie het navorsing getoon dat takseersentrum trektellings nie oor verskillende situasies stabiel is nie. Hierdie bevindinge mag 'n aanduiding wees van 'n lae konstrukgeldigheid van takseersentrums. Navorsers het tot die gevolgtrekking gekom dat navorsingsresultate nie die aanname ondersteun dat takseersentrums dimensietellings genereer wat trekke weerspieel nie. Dit het navorsers laat bespiegel of take (d.w.s. oefeninge), eerder as trekke (d.w.s. dimensies) as 'n basis gebruik behoort te word om takseersentrumbeoordelings te maak. Die doel van die studie was om te bepaal of takseersentrum trektellings beter voorspellers van werksprestasie van bestuurders is as taaktellings. Die studie sluit 97 blanke middelvlakbestuurders van 'n Suid Afrikaanse diensorganisasie in. Geen verskille is tussen die voorspellingsgeldighede van trekgebaseerde en taakgebaseerde tellings verkry nie (r = 0,087 vir beide tellings). Oorsake vir die gebrek aan verskille tussen die voorspellingsgeldighede is bespreek. / In contrast to assessment centre theory, research has shown that assessment centre trait ratings are not stable across different situations. This may be an indication of the relatively low construct validity of assessment centres. Researchers concluded that research results did not support the assumption that assessment centres generate dimensional ratings that represent traits and speculated whether tasks (i.e. exercises) should be used as a basis for making assessment centre ratings, rather than traits (i.e. dimensions). The aim of the study was to determine whether assessment centre task ratings are better predictors of managerial job performance than trait ratings. The study included 97 white middle-level managers of a South African service organisation. No difference was obtained between the predictive validities of traits ratings and task ratings (r = 0,087 for both ratings). Causes for the lack of differences between the predictive validities were discussed. / M. A. (Industrial Psychology)

Optimalisering van leerbekwaamhede by graad nege-leerders: 'n Vergelyking van enkele vakdidaktiese meetinstrumente

Malan, Rencia 19 September 2003 (has links)
In this research study three subject didactical measuring instruments were compared with regard to certain psychometric characteristics of a group of grade nine learners in the Tzaneen and Phalaborwa region, in the Northern Province. The primary goal of this study was to optimize learning competencies with regard to subject context. The SOM-, LEMOSS(II)- and LCH-questionnaires can be applied at the start or at the end of an academic year to an individual or to a group in order to identify learners who need specific help, counseling, remediation and support in the subjects mathematics, natural and domestic sciences in order to facilitate learning. The following aspects have been handled in this study, such as: In chapter 1 an attempt is made to clarify and define the title and certain relevant concepts. The research statement and questions are formulated. The research design is briefly discussed and the primary goal and objectives are set. Other aspects that enjoy attention include the types of research that were used, the method of sampling, data gathering and analysis, as well as the progress of the study. Literature on subject didactics is discussed in chapter 2 for the conceptualising of basic related aspects by means of a macro-model for the optimising of learning competencies in the context of a specific subject. This model emphasises subject content, form and competencies that should be taken into consideration when planning a learning opportunity. Other aspects concerning learning, namely relevant theories, approaches, models, styles, strategies and motives were discussed in order to facilitate learning in mathematics, natural and domestic sciences. In chapter 3 the SOM-, LEMOSS(II)- and LCH-questionnaires as diagnostic instruments are described. The diagnostic value, background, categories and psychometric aspects of the measuring instruments are briefly discussed. In chapter 4 the method of investigation used for the comparison of the SOM- LEMOSS(II)- and LCH-instruments regarding their reliability and validity is described and it includes the goal, hypothesis and method of sampling as an extension of the research design. The way in which descriptive and inferential statistics are conveyed is theoretically described In chapter 5 the results and qualitative conclusions of the empiric-analytical investigation are included. The SOM-, LEMOSS(II)- and LCH-questionnaires are compared with regard to reliability and validity of a group grade nine learners in the Tzaneen and Phalaborwa region. Reliability is discussed by means of test-retest reliability and pared observations. Pared observations include staggering, locality and pared t- and sign-rank testing. Validity refers to criteria referenced validity with regards to simultaneous and predictable validity. Simultaneous validity is described by means of the relation between the subject mark and the field, and by stepwise and multiple regression analysis. In chapter 6 the study is concluded with the brief answering of the research questions and by describing the research findings by means of the research statement. Possible limitations are shown and recommendations for future research are made. / Dissertation (PhD)--University of Pretoria, 2001. / Humanities Education / Unrestricted

Gestruktureerde onderhoud as voorspeller van opleidingsukses vir bestuursdienstepraktisyns / The structured interview as predictor of training success for management services practitioners

Crous, Charl Jacobus 11 1900 (has links)
Die doel van hierdie ondersoek is om die gestruktureerde onderhoud, in die vorm van die Targeted Selection Interview tegniek, as geldige keuringsinstrument ter voorspelling van opleidingsukses van bestuursdienstepraktisyns in die Suid-Afrikaanse Polisiediens te ondersoek. Daar is gebruik gemaak van 'n opnamemetode en die opleidingsprestasie van kandidaatbestuursdienstepraktisyns is vergelyk met die resultate wat kandiddate behaal het in hulle evaluering tydens die gestruktureerde onderhoud. Korrelasies is bereken tussen die tellings behaal vir elke dimensie wat die onderhoud evalueer en die tellings onderskeidelik behaal vir elke opleidingsmodule voltooi tydens die 1 0-weke-bestuurs-dienstesertifikaatkursus wat aangebied word deur die Technikon Pretoria. Die resultate behaal in die ondersoek dui op lae, nie-beduidende korrelasies tussen die gestruktureerde onderhoud as keuringsinstrument en die kandidaatbestuursdienstepraktisyns se prestasie tydens opleiding. Die resultate dui dus daarop dat die Targeted Selection Interview wat die Suid-Afrikaanse Polisiediens toepas, nie opleidingsprestasie voldoende voorspel nie. / The aim of this study is to investigate the validity of the structured interview, in the form of the Targeted Selection Interview technique to predict training success of management services practitioners in the South African Police Service. A survey method has been used to obtain the data regarding the training success of candidates and the evaluation results of the structured interview. The correlation was calculated between scores obtained for every dimension measured by the interview and the scores for every training module compl~ted on the 1 0-week management services certificate course, presented by the Technikon Pretoria. The results obtained indicates low, insignificant correlations between the structured interview as selection instrument and the training results of candidate Management Services practitioners. The results thus indicate that the Targeted Selection Interview as applied by the South African Police Service, does not sufficiently predict training success. / Industrial and Organisational Psychology / M.A. (Bedryfsielkunde)
