The study focuses on challenges in the development of learner-centred and process-oriented teaching and learning in the learning areas, natural science (NS) and mathematics in South African schools. The aim of NS is to develop scientifically literate learners. The three Learning Outcomes (LOs) and the accompanying Assessment Standards (ASs) should enable learners to understand the science products or system of ideas such as underlying theories and principles. The LOs point out the learner’s abilities to use the sciences products or system of ideas. Educators encounter challenges in the application of the LOs and ASs in teaching and learning activities. Against this background, a mixed method study was conducted in selected schools in the Tshwane South District in Gauteng. Data were gathered by document analysis, focus groups and a questionnaire to gauge how the educators are applying the LOs and ASs. Findings indicated that lessons plans were inadequate and educators were not familiar with curriculum documents. / Science and Technology Education / M. Ed. (Natural Sciences Education)

This is an Action Research (AR) study with the senior phase Technology teachers at selected schools of Limpopo Province. The study was motivated by the fact that Technology Education is a foreign concept to many teachers and a new learning area in school curriculum both nationally and internationally. This was exacerbated by the many educational changes that took place in South Africa in the last 18 years. These changes include the overhauling of curriculum, which was the strategic and symbolic change since the first democratic election of 1994, but followed by its review. Thus, a new curriculum known as Curriculum 2005 (reviewed twice already) was developed in which Technology was introduced as a new subject. These changes drastically affected Technology Education and teachers’ coping demands on both the subject content and pedagogy escalated. In this study, AR, a strategy for a systematic, objective investigation with Technology teachers’ who are un- and under- qualified to teach Technology was considered. The study aimed at establishing intervention strategies to empower and emancipate senior phase Technology teachers in Mankweng Circuit from the said challenges above. Thus, the study sought to address the question: How could action research intervention be used to improve the teaching of senior phase Technology teachers who are un- and/or under-qualified? The intervention strategies were implemented through the AR cycles in spiral activities of planning, implementation and observation, action and reflection, whose principles were operationalized to develop participants from the situations that they face in their Technology teaching contexts. The study was designed from both critical theory perspective and participatory paradigm. The following instruments were used as a means to gather data: observations, interviews, questionnaires, field notes, video recording of lesson plans and logs of meetings. The study managed to come up with guidelines to develop and kick start AR with teachers. From the ii findings an AR model was developed to emancipate the un- and under-qualified Technology teachers. Themes from the challenges and AR were used to draft a six weeks plan to empower incapacitated Technology teachers. This investigation was shaped by the initial reflection or preliminary study conducted with the participants called reconnaissance study which revealed specific challenges that Technology teachers encountered daily in their classes. These challenges were turned into the themes, which together with the findings from the preliminary study and interview reflection per cycle were used to design the intervention strategies for the next main cycle. The findings of the study from both the preliminary investigation (presented in Chapter Two) and main AR (presented in Chapter Five) reveal an improvement in the teachers’ understanding and implementation of Technology – they were emancipated to a greater extent from the challenges prior to the AR intervention and post the AR intervention. It is true that coming together as AR co-researchers was the beginning of Technology teaching practice problem identification; keeping together was progressive in Technology teaching; but working together remains our success in Technology teaching then, now and in the future – post doctoral studies. / Curriculum and Instructional Studies / D.

The growing diversity of school populations around the world means that for many learners the language of learning in mainstream classrooms is not their first language. The researcher would submit that content-based second language learning in a context such as a Science classroom is considered advantageous as it enables the learner to manipulate a target language such as English in a way which is meaningful. However, Science learners who have yet to achieve communicative competence in English are disadvantaged when it comes to developing a deep understanding of scientific concepts. Many mainstream Science educators have concerns about this significant group of learners who can be left on the periphery of the class to cope as best as they can. Very often educators aim to meet the needs of English Second Language (ESL) learners without any specific knowledge of the strategies which would enhance learning and ensure that learning environments encourage participation and interaction. The learners themselves have not only to deal with language and sociocultural issues but must face the cognitive demands of Science including negotiating its specialized language. The aim of this study was to investigate how the use of English as a language of learning and teaching Science in rural secondary schools in the Vlakfontein Circuit of the Limpopo Capricorn District, influenced the ability of Grade 8 students to learn Science. The focus was on the Grade 8 classes since they are at the threshold of their educational pursuit. The study had two main purposes. The first goal was to describe the current situation with respect to rural secondary school learners and their educators in selected learning environments in Vlakfontein Circuit. The second goal was to bring about improvement in the learners’ situations by employing specifically designed interventions. The study had three focal areas: the language; the teaching and learning environment; and the ESL learner. The investigation was conducted in disadvantaged rural secondary schools in the Vlakfontein Circuit in the Limpopo province. Observations of the Science classes revealed that, even for the learners with very limited English language proficiency there was little ESL specialist support available. The data analyzed was collected using a variety of data collection tools. The main data generation tools were observation, semi-structured interviews and questionnaires. The analysis revealed that learners were lacking in Science register (terminology). This study also found out that non-technical language used in Science lessons affected the learners’ understanding much more than the educators were aware. Educators’ attitudes and beliefs strongly influenced the interaction and participation of ESL learners in Science classrooms. The study also revealed that developing language skills prevented ESL learners from asking questions and answering questions in class and academic progress in Science was impeded by limited opportunities for ESL learners to clarify their understanding. Further, the investigation established that achievement in Science and in education overall was affected by assessment instruments which were infused with specific linguistic or cultural knowledge. The study arrived at a conclusion that the needs of the research students could not be met by a programme based on the traditional format of ESP teaching. Hence, the researcher has recommended a Science Based English Programme (SBEP) which encapsulates several adjustments in orientation methods and materials to meet the ESL learners’ needs. This kind of learning-centred arrangement will allow not only efficiency of SBEP instruction but also allow the kinds of activities that may not be possible in groups with a wide dispersion of interests. However, the extent to which the research learners encountered difficulties with vocabulary suggests that there is a need to investigate more effective methods of dealing with this issue. Needed research could also be directed into the development of a Science glossary with appropriate language levels for ESL learners. This could include technical scientific terms with examples of how terms can be used.From the outcome of the interviews with educators, it is evident that further research is needed concerning the educators’ English proficiency and Science competence in ESL situations. / Teacher Education / D.

Lewisville Lake Environmental Learning Area (LLELA) is an 809-hectare property in Denton County, TX. A study of the vegetation community identified 466 species in 104 families, with 25% of the species from only two families, Asteraceae and Poaceae. The property demonstrates the characteristics of an early successional community, dominated by weedy species. Prairie communities are dominated by Johnson grass and ragweed, with climax tall grass prairie communities only in areas that have been planted with native grass seed. Forest communities are similarly in an early successional stage, dominated by the hackberry-elm-ash alliance, with small remnants of native Cross Timbers found in isolated patches. Species richness and diversity were highest in the forests and lowest in the wetlands; evenness, though not different across ecosystems, demonstrated a strong seasonal component. The species list was compared with previously reported lists for Denton County, and 256 species identified had not been previously reported for the county. A wetland restoration study was conducted to determine if there was a difference in survival and growth between potted transplants with intact root systems and bare-root transplants. Two different mesh sizes were used for protection, and the success of the different caging was evaluated. Of eight species, only four survived through the second growing season. There was no significant difference in the success of the propagule types for Sagittaria latifolia. The treatments planted with intact root systems showed significantly higher growth and reproduction than the bare-root treatments for Eleocharis quadrangulata, Heteranthera dubia, and Vallisneria americana. There was no survival recorded in the coarse mesh cages, likely due to the presence of crayfish that are able to get through the coarser mesh and feed on the transplants.

Text in Afrikaans / Summaries in Afrikaans and English / This study aims to investigate and explain how the L2 -facilitator can effectively employ the various facilitation skills of language teaching in Afrikaans Second Language within the Outcomes Based Education framework in the learner-centred classroom. The facilitator is critical in providing an opportunity for multicultural learners to develop the necessary language learning skills to enjoy Afrikaans Second Language/Additional Language learning as an interesting learning experience within a positive learning milieu. In the learner-centred U -classroom, learners too must accept responsibility for their own and their peers' learning within the co-operative learning group. This study reveals how the L2 -facilitator can develop the necessary knowledge and skills concerning groupwork, such as the strategies enhancing L 2 -learning, effective group facilitation skills, learner attitudes towards the facilitator, problem-solving skills, co-operative learning as a control technique, communication, learners' behaviour and the advantages of groupwork. Furthermore, elements of classroom negotiation and the facilitator's methods of working in this negotiated partnership are also discussed. Since language learning is integral to lifelong learning, multicultural learners must be motivated to learn Afrikaans Second/ Additional language with greater enthusiasm. This necessitates the L2 -facilitator creating an interesting, challenging and authentic language learning environment where mutual respect and trust are emphasised. This study reveals how the L2 -facilitator could develop his/her knowledge of task-based L2 -teaching and use it with the effective techniques of facilitation and negotiation skills in the taskorientated second language classroom to lead learners to effective Afrikaans L2 -learning. The new National Language Standardisation Policy 200112002 necessitates the facilitator of Afrikaans L 2 -teaching/learning within the Outcomes Based Education framework and the revised Curriculum 2005 to be aufait with assessment and his/her role in assessment. Being knowledgeable on the various criteria and strategies regarding assessment is therefore imperative. Finally, chapter five illustrates practically how the facilitator could plan, organise, base, integrate and present authentic Afrikaans L 2 -lessons/work based on the theoretical knowledge and aspects of facilitation skills, group-work, task-based learning and assessment discussed in chapters two to four. / Daar word in die studie gepoog om te ondersoek en te verduidelik hoe die T2-fasiliteerder die verskillende fasiliteringsvaardighede ten opsigte van T2 -Afrikaansonderrig binne die UGO -raamwerk in die leerdergesentreerde T2-klaskamer effektief kan gebruik.
