Thesis (MEd)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This thesis explores the use of educational technologies in grades 10 to 12 life sciences classrooms at a local high school. I argue that the application of educational technologies in science classrooms has the potential to engender critical teaching and learning, and to contribute to professional development. By reflecting on my own professional development as a science teacher over the past three years (2008-2010), I show that the use of educational technologies cultivates moments of critical pedagogy that link strongly with reflective teaching, critical thinking and transformative learning. Drawing on two intertwined narratives, I show how educational technologies can enhance reflective teaching whereby, firstly, teachers can take seriously theories and expertise in their practices; secondly, organise their classrooms so as to facilitate critical learning; and, thirdly, take up broader institutional and social issues. In addition, I show that the use of educational technologies opens up pedagogical spaces for critical thinking and transformative learning – that is, whereby learners learn creatively, actively, engagingly and reflecting on their own practices. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die gebruik van onderwystegnologie in grade 10 tot 12 lewenswetenskapklaskamers by ʼn plaaslike hoërskool. Ek argumenteer dat die toepassing van onderwystegnologie in wetenskapklaskamers die potensiaal het om kritiese onderrig en leer teweeg te bring, en ʼn bydrae tot professionele ontwikkeling te maak. Deur te reflekteer op my eie professionele ontwikkeling as ʼn wetenskaponderwyser oor die afgelope drie jaar (2008-2010), dui ek aan hoedat die gebruik van onderwystegnologie krities pedagogiese oomblikke kultiveer wat sterk aanklank vind by reflektiewe onderrig, kritiese denke en transformatiewe leer. Met betrekking tot twee narratiewe dui ek aan hoedat onderwystegnologie reflektiewe onderrig kan bevorder deurdat, eerstens, onderwysers teorieë en kundighede in hulle gebruike ernstig opneem; tweedens, klaskamers organiseer om kritiese leer te fasiliteer; en derdens, breër institusionele en sosiale kwessies aanspreek. Daarenbowe dui ek aan hoedat onderwystegnologie ook pedagogiese ruimtes vir kritiese denke en transformatiewe leer bied – dit is, waarby leerders kreatief, aktief en betrokke is, en op hulle eie praktyke reflekteer.

Thesis (MEdPsych)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Education, both in South Africa and internationally, experiences a number of challenges with regards to the need for improved teaching and learning. South African education is in a state of transformation to address the country's educational needs. In science education specifically, there is a heightened necessity to develop teaching that will respond to distinctive educational needs in the sciences. Many of the educational issues, presented in current literature, are mirrored in my Natural Sciences classroom. Given the benefits of enhanced metacognition for effective learning, this study aimed to investigate the use of metacognitive instruction procedures to improve my Natural Sciences teaching practice. Consequently, it also aimed to explore the influence that this may have on the metacognitive development of my Grade 9 Natural Sciences learners. This research study was based on a social constructivist perspective that views learning as a unique, internalized construction of knowledge from a social interaction, such as teaching. This study was embedded within a paradigm of praxis, with a qualitative action research cycle forming the research methodology and design respectively. Purposeful sampling was used to select nine of my Grade 9 Natural Sciences learners to act as informants for the Grade 9 class. Data was collected in the form of learner reflections, an open-ended questionnaire, a focus-group interview, and a research journal. Furthermore, the data was analysed, using a theoretically founded coding scheme, to identify and interpret significant themes and/or trends. The research findings indicated that the employed metacognitively orientated teaching procedures enhanced my Grade 9 Natural Sciences learners' metacognition. Their metacognitive awareness and reflection abilities improved, as well as their knowledge and regulation of cognition. The teaching techniques also demonstrated the potential to facilitate the development of my learners' conscious thinking, self-discipline, responsibility and active participation in learning - all characteristics envisaged for the ideal South Africa learner. In addition to this, the research process demonstrated the ability to enhance my Natural Sciences teaching practice and the information gained from this study will be used to inform my future teaching practice. I now realise the value of incorporating metacognitive teaching procedures into my lessons, as well as the importance of reflecting on my teaching process and considering the uniqueness of each learner in my class. Additionally, teacher training institutes and educational policy makers may benefit from the information gained from this study, for improving teaching practice. Apart from this, findings attained from this study have the potential to inform future cycles of this action research process or alternatively to be used for other research within the field. / AFRIKAANSE OPSOMMING: Onderwys, beide in Suid-Afrika en internasionaal, ervaar 'n aantal uitdagings rakende die behoefte aan verbeterde onderrig en leer. Die Suid-Afrikaanse onderwysstelsel is tans in 'n staat van transformasie om die land se opvoedkundige behoeftes aan te spreek. In die wetenskap-onderwys spesifiek, is daar 'n toenemende noodsaaklikheid om onderrig te ontwikkel wat die unieke onderwysbehoeftes in die wetenskappe kan aanspreek. Baie van die opvoedkundige kwessies soos in huidige literatuur uitgelig, is ook in my Natuurwetenskappe-klaskamer teenwoordig. Gegee die bewese voordele van verbeterde metakognisie vir effektiewe leer, het hierdie navorsingstudie gepoog om die gebruik van metakognitiewe onderrigprosedures vir die verbetering van my Natuurwetenskappe-onderrigpraktyk te ondersoek. Die studie was ook daarop gemik om die invloed van metakognitiewe onderrigprosedures op die metakognitiewe ontwikkeling van my Graad 9 Natuurwetenskappe-leerders, na te vors. Hierdie navorsingstudie is gebaseer op 'n sosiaal-konstruktivistiese leerperspektief wat leer sien as 'n unieke, geïnternaliseerde konstruksie van kennis binne 'n sosiale interaksie, soos onderrig. Hierdie studie is binne 'n paradigma van „praxis‟ ingebed, met aksienavorsing as navorsingsontwerp en daar is van „n kwalitatiewe navorsingsmetodologie gebruik gemaak. Doelgerigte steekproefneming is gebruik om nege van my Graad 9 Natuurwetenskappe-leerders te kies om as informante vir die graad 9-klas op te tree. Data is in die vorm van leerders se refleksies, 'n oop-einde vraelys, 'n fokusgroep-onderhoud, en 'n navorsings- joernaal ingesamel. Verder is die data met behulp van 'n teoretiese koderingskema geanaliseer wat belangrike temas en/of tendense identifiseer en interpreteer. Die navorsing het aangedui dat die metakognitiewe onderrigprosedures wat gebruik is, my Graad 9 Natuurwetenskappe leerders se metakognisie versterk het. Hulle metakognitiewe bewustheid en reflektiewe vermoëns het verbeter, sowel as hulle kennis en regulering van kognisie. Die onderrigtegnieke het ook die potensiaal getoon om die ontwikkeling van my leerders se bewuste denke, self-dissipline, verantwoordelikheid en aktiewe deelname in die leerproses te fasiliteer. Hierdie eienskappe is van dié wat vir die ideale Suid-Afrikaanse leerder beoog word. Benewens hierdie aspekte het die navorsing ook my Natuurwetenskappe-onderrigpraktyk verbeter en die navorsingsbevindinge sal in die toekoms gebruik word om my onderwyspraktyk toe te lig. Ek besef nou die waarde daarvan om metakognitiewe onderrigprosedures in my lesse te inkorporeer, sowel as die belang van refleksie oor my onderrigproses en om die uniekheid van elke leerder in my klas in ag te neem. Onderwys-opleidingsinstellings en opvoedkundige beleidmakers mag uit hierdie navorsing voordeel trek rakende die verbetering van onderwyspraktyk. Afgesien van die bogenoemde, het die navorsingsbevindinge ook die potensiaal om toekomstige siklusse van aksienavorsing toe te lig en om binne verdere navorsing in die veld gebruik te word.

Thesis (MEd)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: South Africa is in the midst of a mathematics and science education crisis that challenges all key role-players. The Institute for Mathematics and Science Teaching at the University of Stellenbosch (IMSTUS), was involved in several university-school partnership (systemic intervention) projects that sought to provide continuing professional development to mathematics and science teachers and to help them make a greater impact on the learners that they teach. One of these intervention projects was the Sciences and Mathematics Initiative for Learners and EducatorS (SMILES) that targeted mathematics and science teachers and learners in under-resourced schools in the Western Cape. The effects of an intervention aimed at supporting and enhancing teacher professional development will only be seen in the learners once teachers have accepted and mastered the pedagogies proposed. Professional development that does not “enthuse, support, train and renew, and encourage” will probably fail. When considering this, the question that must be asked is whether the SMILES project was in fact enthusing, supporting, training, renewing and encouraging. The purposes and aims of the SMILES project with specific reference to professional development of science teachers were to enhance teachers’ pedagogical content knowledge and address the critical issues confronting science education of which three are: constructivist teaching, understanding the nature of science, and scientific argumentation. The characteristics of effective professional development, the core features of professional development and the theoretical constructs to evaluate professional development of teachers were used in this study to evaluate the effectiveness of the model used in the SMILES project. A concurrent version of the mixed method approach was adopted for the collection and analysis of the data. Although causality is always difficult to prove in a school setting because of the many variables that affect student performance, improved student achievement is the ultimate litmus test for teacher professional development effectiveness. Analysis of the National Senior Certificate results of the project schools compared with the National and Provincial results indicated that the project schools on the whole fared better than the National results. The project schools outperformed the national and provincial results for Life Sciences in 2011, 2012 and 2013 by at least four percentage points. The highest result achieved was 85,5% in 2011. In 2012 and 2013 these results were 82,7% and 83,0% respectively. In Physical Sciences the project schools started with results below that achieved nationally (34,7%) and then ended up with a pass percentage within half a percentage point of the provincial result (72,1%). The Mathematics results were not as positive. The project schools started by achieving a 63,4% pass rate and ended with a percentage pass rate of 63,3% having initially taking a dip down to 51,3%. At the end of the intervention the Mathematics results were better than the national results but were 10% lower than the Provincial average. Although it is difficult to pin down the results solely to the effects of the intervention, the comparison with provincial and national results reasonably controls for most of the extraneous variables including variations in enrolments in these subjects. On the affective side it is almost certain that the attitude of the learners and the teachers toward their respective subjects improved during the tenure of the project. This could have had a positive effect on the National Senior Certificate results achieved by the project schools. / AFRIKAANSE OPSOMMING: Suid-Afrika is midde in 'n wiskunde en wetenskap onderwyskrisis wat alle sleutelrolspelers uitdaag. Die Instituut vir Wiskunde en Wetenskaponderwys aan die Universiteit van Stellenbosch (IWWOUS), was betrokke by verskeie universiteit-skool vennootskapsprojekte (sistemiese intervensie) wat gepoog het om voortgesette professionele ontwikkeling te bied aan wiskunde en wetenskap onderwysers en hulle te help om 'n groter impak op die leerders wat hulle onderrig, te maak. Een van hierdie intervensie-projekte was die Wetenskappe en Wiskunde-inisiatief vir leerders en opvoeders (SMILES) wat wiskunde en wetenskap onderwysers en leerders, in hulpbronarm skole in die Wes-Kaap, geteiken het. Die impak van 'n intervensie wat daarop gemik is om onderwyser professionele ontwikkeling te ondersteun en bevorder, sal eers in die leerders waargeneem kan word, wanneer onderwysers die voorgestelde pedagogieë aanvaar en bemeester. Professionele ontwikkeling wat nie "begeester, ondersteun, oplei en vernuwe asook aanmoedig” nie, sal waarskynlik misluk. Hierdie stelling in ag genome, is die vraag wat gevra moet word, of die SMILES-projek werklik onderwysers begeester, ondersteun, opgelei, vernuwe en aangemoedig het. Die doelstellings en doelwitte van die SMILES projek, met spesifieke verwysing na die professionele ontwikkeling van Wetenskap-onderwysers, was om onderwysers se pedagogiese inhoudelike kennis te versterk en om kritieke kwessies waarmee wetenskap-onderwys gekonfronteer word, aan te spreek. Drie van hierdie kwessies is, konstruktivistiese onderrig, begrip van die aard van wetenskap en wetenskaplike argumentering. Die eienskappe van effektiewe professionele ontwikkeling, die kern kenmerke van die professionele ontwikkeling en die teoretiese konstrukte om professionele ontwikkeling van onderwysers te evalueer, is in hierdie studie gebruik om die doeltreffendheid van die model wat in die SMILES-projek gevolg is, te evalueer. 'n Gelyklopend gemengde-metode benadering is gevolg vir die insameling en ontleding van die data. Hoewel oorsaaklikheid altyd moeilik is om in 'n skoolopset te bewys, as gevolg van die baie veranderlikes wat studente se prestasie beïnvloed, is verbeterde studente prestasie die uiteindelike lakmoestoets vir doeltreffendheid van professionele onderwyser-ontwikkeling. Ontleding van die Nasionale Senior Sertifikaat-uitslae van die projek-skole, in vergelyking met die nasionale en provinsiale resultate, dui daarop dat die projek-skole oor die algemeen beter gevaar het as die nasionale uitslae. Die projek-skole het die nasionale en provinsiale skole se resultate vir Lewenswetenskappe in 2011, 2012 en 2013 met ten minste vier persentasie punte oortref. Die hoogste resultaat behaal was 85,5% in 2011. In 2012 en 2013 was hierdie uitslae onderskeidelik 82,7% en 83,0%. In Fisiese Wetenskappe het die projek-skole met resultate onder wat nasionaal behaal was (34,7%) begin, en geëindig met ʼn uiteindelike slaagpersentasie binne 'n halwe persentasiepunt van die provinsiale resultate (72,1%). Die wiskunde-uitslae was nie so positief nie. Die projek-skole het begin met 'n 63,4% slaagsyfer en geëindig met 'n slaagpersentasie van 63,3% na ʼn aanvanklike insinking na 51,3%. Aan die einde van die intervensie was hul Wiskunde-resultate beter as die nasionale resultate, maar 10% laer as die provinsiale gemiddelde. Alhoewel dit moeilik is om die resultate slegs vas te pen aan die gevolg van die intervensie, dien die vergelyking met provinsiale en nasionale resultate as redelike kontroles vir meeste van die eksterne veranderlikes insluitend variasies in inskrywings in hierdie vakke. Op die affektiewe vlak is dit byna seker dat die gesindheid van die leerders en die onderwysers ten opsigte van hul onderskeie vakke verbeter het tydens die projek. Dit kon moontlik 'n positiewe uitwerking op die projek-skole se Nasionale Senior Sertifikaat resultate gehad het.

Innovative educators seek technologies to facilitate or enhance the learning experience while taking nothing away from the message of instruction. Simulations have been shown to meet this requirement. While simulations cannot replace the teacher or the message of instruction, they can provide a deeper and more cognitively engaging learning experience. Classroom use of simulations has been ongoing since the 1960's. However, substantive research on their efficacy remains limited. What research has been conducted indicates that simulations possess great potential as aids to instruction. The author of this dissertation pursued this question focusing on whether simulations contribute to instruction by facilitating transfer, improved motivation and increased engagement. This dissertation documents a study in which instructional simulations were used in undergraduate science courses to promote engagement, transfer and knowledge-seeking behavior. The study took place at Midwestern State University (MSU), a public university located in north-central Texas with a student population of approximately 5,500. The study ran during the fall 2006 and spring 2007 terms. Samples consisted of students enrolled in GNSC 1104 Life / Earth Science during the fall term and GNSC 1204 Physical Science during the spring term. Both courses were offered through the Department of Science and Mathematics at MSU. Both courses were taught by the same professor and are part of the core curriculum for undergraduates in the West College of Education at MSU. GNSC 1104 and GNSC 1204 yielded samples of n = 68 and n = 78 respectively. A simulation focusing on earthquakes was incorporated into the curriculum in GNSC 1104 while a simulation which presented concepts from wave propagation was included in GNSC 1204. Statistical results from this study were mixed. Nevertheless, studies of this type are warranted to gain a more complete understanding of how students are impacted by their interactions with simulations as well as the role simulations can play in the curriculum.

A review of the literature shows that there is much evidence to suggest the challenges facing Hispanic students in American public schools. Hispanic enrollment in K-12 public schools has increased from 6 to 19% in the last thirty years, yet schools have not made adequate adjustments to accommodate this changing population. Issues such as remedial tracking and cultural differences have led to low high school graduate rates for Hispanic students and inequities in schooling experiences (Gay, 2000). Particularly in the area of science, Hispanic students struggle with academic success (Cole & Espinoza, 2008). Despite these obstacles, some Hispanic students are academically successful (Rochin & Mello, 2007; Merisotis & Kee, 2006). This dissertation tells the stories of these Hispanic students who have been successful in science in secondary public schools. This study followed a grounded theory methodology and utilized individual interviews to collect data about Hispanics who have demonstrated achievement in the area of science. Through the analysis of these interviews, factors were identified which may have contributed to the success of these Hispanics in the field of science. Implications for future practice in public schools are also discussed.

This study contributed to the body of research that supports a holistic model of afterschool learning through the design of an afterschool intervention that benefits elementary school students of low socioeconomic status. This qualitative study evaluated a science focused afterschool curriculum that was designed using principles from Risk and Resiliency Theory, academic motivation theories, science core ideas from the Next Generation Science Standards, and used environmental education philosophy. The research question of this study is: how does an outdoor and STEM based afterschool program impact at-risk students' self-efficacy, belonging and engagement and ability to apply conceptual knowledge of environmental science topics? The study collected information about the participants' affective experiences during the intervention using structured and ethnographic observations and semi-structured interviews. Observations and interviews were coded and analyzed to find patterns in participants' responses. Three participant profiles were developed using the structured observations and ethnographic observations to provide an in depth understanding of the participant experience. The study also assessed the participants' abilities to apply conceptual understanding of the program's science topics by integrating an application of conceptual knowledge task into the curriculum. This task in the form of a participant project was assessed using an adapted version of the Portland Metro STEM Partnership's Application of Conceptual Knowledge Rubric. Results in the study showed that participants demonstrated self-efficacy, a sense of belonging and engagement during the program. Over half of the participants in the study demonstrated a proficient understanding of program concepts. Overall, this holistic afterschool program demonstrated that specific instructional practices and a multi-modal science curriculum helped to support the social and emotional needs of at-risk children.

The purpose of this study was to investigate the difference in the enjoyment, interest, perceived learning, and achievement levels of third grade students when social studies and science units were presented as interrelated subject units versus separate subject units. Eight units in social studies and science were chosen. Four of these units were selected at random to be presented as interrelated subject units and four to be presented as separate subject units. Interrelated units used the social studies or science topic as a core, and lessons in other subjects such as language arts, math, music, and art were related to this basic topic. Separate subject units focused on the particular topic of the unit and were not intentionally related to other subjects in curriculum. An attitude questionnaire and achievement test were administered as posttests after each unit. The results of the tests for matched pairs indicated a significant difference in the levels of enjoyment, interest, perceived learning, and achievement for the two types of units. It was concluded that the 28 third grade students taught using interrelated subject units showed a significantly higher level of enjoyment, interest, perceived learning, and achievement than the same group when taught using separate subject units.

D.Litt.et Phil. (Information Science) / Schools of library and information science, like all professional schools, are tied to the profession they prepare their students for. They must balance the needs and demands of the profession they serve and the needs and demands of the educational institution they form part of. In South Africa and elsewhere, there is a perceived gap between the product the library schools deliver and the needs of the library and information profession. The technikons in South Africa are relative newcomers to the training and education of librarians and information workers. Their task is seen mainly as the training of paraprofessional library workers, since it is the aim of technikons to provide relevant, vocational education and training through co-operation with the relevant industries/professions. The qualification structure of technikons makes provision for different levels of undergraduate qualifications in the form of national certificates, national higher certificates, diplomas and since 1994, technikon degrees. The conventional qualification structure used for library and information science training, does not however make provision for certificate qualifications - technikons at this stage offer only the National Diploma: Library and Information Practice. There is presently no possibility for technikon diplomates to upgrade their paraprofessional qualification to professional level. The education and training of librarians and information workers through the medium of distance education is well established in South Africa. The distance education institutions use the same qualification structure as the residential institutions, despite the fact that qualifying through parttime distance education takes much longer. Distance learners therefore could benefit from interim qualifications like certificates, since it could serve as indication to their employers that they are making progress with their studies. There are indications from the library and information science profession that there is a need for more undergraduate levels of qualifications because of the different needs of the different communities in South Africa, especially those of the disadvantaged communities. The qualification structure for library and information science education at Technikon SA, which teaches through the medium of distance education, can however not be changed without consulting the library and information profession. The aim of this study is to determine whether the profession would accept a changed qualification structure. To determine this, the Delphi method is used. The Delphi method is a technique that makes use of the opinions of experts for forecasting future events. The Delphi study is supported by a literature study which serves to put the research into context by ...

M.Ed. / Renewal represents an improvement in accepted existing practice. This implies that the old practice is just not good enough any longer. Similarly, the knowledge and training base of lecturers at technical colleges fell short with the introduction of the new National Intermediate Certificate, as well as the National Senior Certificate in 1992. The subject-related problems which emerged, could have been solved by various techniques. The quality circle, self-directed work team and support groups, are three group-related problem-solving techniques to be assessed in this study. The three techniques share group participation as a common characteristic. Each of these techniques still maintains a unique approach and method in solving a problem. One would have a remarkable problem-solving technique if one could capitalise on all the positive aspects of the various techniques. The introduction of the new National Intermediate Certificate and the National Senior Certificate, is a direct result of adherence to community needs. The new courses demanded implementation of computer training in various fields of study at technical colleges. A curriculum analysis focusing on Parktown College, led to the identification of three fields of study affected by the introduction of the computer. Lecturers responsible for computer training experienced and still experience various problems. These problems were identified by means of a focus group interview.
