The purpose of the study is to explore teacher’s classroom practices when teaching electric circuits in a grade 12 classroom. This qualitative interpretive study involves three participants who perceive electric circuits to be a difficult topic to teach in the Tshwane west district, Gauteng Province. The study uses the Classroom Practice Diagnostic framework to present and analyse results. Pseudonyms are used to protect the identities of the participants. The study reveals that teachers’ classroom practices differ from one participant to the other, despite the same perception that electric circuits is a difficult topic to teach. / Ndivho khulwane ya ngundo/Tsedzusulo iyi ndi u bveledza na u tandavhudza mugudisi kha ngudo dza kilaŝini musi a tshi gudisa sekhethe dza mudagasi kha gireidi ya 12(ya vhufumbili) kilasini.

English, Afrikaans and Northern Sotho summaries / Die algemene doel van hierdie navorsing was om ’n loopbaantevredenheids- en indiensneembaarheidsprofiel vir kenniswerkers saam te stel, gebaseer op die verhoudingsdinamika tussen individue se biografiese eienskappe (ouderdom, ras en indiensnemingstatus), loopbaankognisies (loopbaanaanpasbaarheid en psigososiale loopbaanpreokkupasies as voorgangers), hulle psigososiale loopbaanhulpbronne (indiensneembaarheidskenmerke, loopbaanankers en loopbaanwaardes as moderators) en hulle loopbaantevredenheid en selfwaargenome indiensneembaarheid (gevolge of uitkomste). Die einddoel van die navorsing was om gevolgtrekkings te maak oor die verhoudingsdinamika (omvang en rigting) tussen die konsepte ten einde organisatoriese loopbaanontwikkelingspraktyke vir die kenniswerker voor te stel. ’n Kwantitatiewe deursneenavorsingsbenadering is gevolg en het ’n steekproef van N = 404 kenniswerkers behels wat by professionele Suid-Afrikaanse liggame geregistreer is. Beskrywende, korrelasie- en meerveranderlike inferensiële statistiek is ingespan. Aanvullend tot die kanoniese korrelasieresultate, het regressie and strukturele vergelykingsmodellering ontledings aangetoon dat die loopbaantevredenheidsprofiel unieke beïnvloedingsfaktore het terwyl die selfwaargenome indiensneembaarheidsprofiel ook oor sy eie unieke beïnvloedingsfaktore beskik. Moderering regressie-ontleding het gewys dat individue se loopbaankognisies (dit is die vlakke van loopbaanaanpasbaarheid en loopbaanpreokkupasies) nie voorwaardelik ten opsigte van hulle psigososiale loopbaanhulpbronne was (dit is, indiensneembaarheidseienskappe, loopbaanankers en loopbaanwaardes) om hulle vlakke van loopbaantevredenheid en selfwaargenome indiensneembaarheid te verduidelik nie. Die loopbaankognisies en psigososiale loopbaanhulpbronne het individuele, bepaalde hoofgevolge om te oorweeg ten einde kenniswerkers se loopbaantevredenheid en selfwaargenome indiensneembaarheid te verstaan. Stapsgewyse regressie en hiërargies-moderering regressie-ontleding het gewys dat ouderdom, ras en indiensnemingstatus belangrike oorwegings was wat betref die loopbaantevredenheidsprofiel van kenniswerkers. Ras in die besonder het geblyk belangrik te wees om in aanmerking te neem ooreenkomstig hulle selfwaargenome indiensneembaarheid. Verskille tussen die biografiese groepe het ook aan die hand gedoen dat unieke loopbaanontwikkeling oorweeg moet word in multikulterele, diverse werkskontekste. Die loopbaantevredenheid en indiensneembaarheidsprofiel is saamgestel, gebaseer op die belangrikste insigte wat uit die essensiële, betekenisvolle bevindings bekom is. Loopbaantevredenheid en indiensneembaarheidsteorie is in hierdie navorsing uitgebrei. Aanbevelings vir organisatoriese loopbaanontwikkelingondersteuningspraktyke is gemaak, gebaseer op die voorgestelde profiel vir die professionele kenniswerker. / Maikemisetsomagolo a dinyakisiso e bile go go hlama phrofaele ye e kgotsofatsago mosomo le go thwalega mosomong go basomi ba tsa tsebo go lebeletswe seemo sa dikamano magareng ga dipharologantsi tsa dipalopalo ka ga batho (e lego mengwaga, bong, mohlobo le maemo a mosomo), go kwesisa ka ga mesomo (go tlwaela mosomo le seemo sa menagano ya setshaba ka ga mesomo bjalo ka dilo tseo di tlago peleng), methopo ya bona mosomo mabapi le menagano ya setshaba (dikokwane tsa go kgona go thwalega mesomong, dihlohleletsi tsa go hwetsa mesomo le maitshwaro a mesomong bjalo ka dilo tseo di lekolago mesomo) le go kgotsofatsa ga dinyakwa tsa mesomo le go ipona bjalo ka yo a thwalegago (seo se tlago ka moragonyana goba bjalo ka poelo).

The end goal of the research was to draw conclusions on the relationship dynamics (magnitude and direction) between the constructs for the purpose of proposing organisational career development practices for the knowledge worker. A quantitative cross-sectional research approach was followed and involved a sample of N = 404 knowledge workers registered with South African professional bodies. Descriptive, correlation and multivariate inferential statistics were performed. Supplementary to the canonical correlation analysis, regression and structural equation modelling analysis indicated that the career satisfaction profile has unique influencing factors while the self-perceived employability profile also has its unique influencing factors. Moderated regression analysis showed that individuals’ career cognitions (i.e. levels of career adaptability and psychosocial career preoccupations) were not conditional upon their psychosocial career resources (i.e. employability attributes, career anchors and career values) in explaining their levels of career satisfaction and self-perceived employability. The career cognitions and psychosocial career resources had individually specific main effects to consider in understanding knowledge workers’ career satisfaction and self-perceived employability. Stepwise regression and the hierarchical moderated regression analysis showed that age, race and employment status were important to consider in terms of the career satisfaction profile of knowledge workers. Race seemed especially important to consider in terms of their self-perceived employability. Differences among the biographical groups also suggested unique career development needs to consider in multi-culturally diverse work contexts. The career satisfaction and employability profile was constructed based on the key insights derived from the core significant findings. The research extended career satisfaction and employability theory. Recommendations for organisational career development support practice were made based on the proposed profile for the professional knowledge worker. / Psychology / Ph. D. (Psychology)

Text in English with abstracts in English, Afrikaans and Tswana with keywords in English and Tswana / Displacement in the South African context is a complex and diverse phenomenon which is under-researched, particularly from the point of view of post-resettlement stress. The Meetse-a-tala community from Groenwater, Northern Cape, was resettled in 1964 and returned in 1999 to their ancestral land after a 25 year struggle to do so. The community anticipated that the land would present all the natural resources they had in 1964, but unfortunately, when they returned, the outlook seemed a lot different. / Verskuiwing in die Suid-Afrikaanse konteks is ‘n diverse en komplekse verskynsel wat nog nie voldoende nagevors is, veral vanuit die oogpunt van post-hervestigingsstres nie. Die Meetse-a-tala-gemeenskap van Groenwater in Noord-Kaap is in 1964 hervestig en het in 1999 teruggekeer na die land van hul voorouers na ‘n 25 jaarlange stryd om dit te bewerkstellig. Die gemeenskap het verwag dat die gebied weer al die natuurlike hulpbronne sou aanbied wat hulle in 1964 gehad het, maar ongelukkig, met hul terugkeer, het die vooruitsigte heel anders gelyk. / Tiragalo ya go fudusiwa ka dikgoka mo bokaong jwa Aforikaborwa e tlhagisa marara a a farologaneng ka ntlha ya dipatlisiso tse di lekanyeditsweng malebana le kgatelelo ya maikutlo e e amanang le morago ga go fudusiwa.
