M.Ed. (Curriculum Studies) / Education must be seen as dynamic, that is responding to the demands made on it by science, technology and society. According to Fay (1975: 19) natural science has provided men with a certain kind of knowledge by means of which they can control their natural environment by making it more hospitable and more productive. It is for this reason that technology and science are seen as exercising a great influence on our daily lives. Changes in the nature of high school population and the geometrically - increasing quantity of scientific knowledge are identified as causes leading to the changes in the high school Biology; curriculum (Falk, 1971: 21). The introduction of the new senior Biology syllabus to Soweto secondary schools should be seen as a reaction to changes in the nature of scientific knowledge. According to a report of a Workshop held by SCISA (Science Curriculum Initiative for South Africa) at Michael house, 11-12 January 1989, it was realized that the current syllabus, and syllabus development and implementation processes are "out of balance and in need of review, This implies that the current syllabus fails to meet the needs of the learner as well as those of society.

The problem of this study was a comparison of attitudes toward and achievement in biology between students enrolled in an introductory biology course taught using instructional television and as taught at Tarrant County Junior College South Campus in the spring semester of 1982.

South Africa needs an economy which is competitive and successful. Therefore, it is important that an education system will provide a skilled work force. Learners need to develop biology skills that will equip them for life, enable them to solve problems and think critically. Unfortunately South Africa is presently encountering a lack of skilled citizens. The reasons for this most probably is that the biology curriculum is mainly discipline-based, content-loaded and largely irrelevant, resulting in learners not furthering their studies in biology and related fields. The biology matriculation examination has a strangle hold on what is taught. Lengthy, content-loaded curricula emphasise the memorising of facts by means of expository teaching methods, leaving little opportunity to teach the application of information and skills to solve problems in real life situations. The teaching methods of biology are thus not sufficiently stimulating and motivating. Biology teaching should not only concentrate on facts or explain facts to learners, but should also concentrate on ways or processes by means of which these facts can be obtained. To implement a process approach where learners can develop basic- and integrated skills is not an easy task for those involved. The empirical research of this study, confirmed the findings throughout the literature study that various factors hamper the effective implementation of the process approach. It is important that negative factors such as 'large classes' and 'a lengthy syllabus' (in historically disadvantaged [HD] and advantaged schools [HA]) and 'lack of equipment' and 'resource material' (only in HD schools) which received high percentages in the survey, will duly be considered when implementing the process approach, curriculum 2005 or 21. These factors can exert a powerful influence on the success of any changes in biology education. To ensure the successful implementation of the process approach it is important that all teachers receive adequate in-service training to keep abreast with new teaching strategies and methods / Educational Studies / D.Ed.

One of the principles regarding our knowledge about life on earth is that no organism can be fully understood without taking into account its surrounding environment. This study examines the extent to which ecosystem-focused field studies may be associated with students' academic performance and potential to contribute to the advancement of science and conservation. Pilot studies conducted in Panama and California established methods used in this project from 1993-2003. Two hundred and sixty-seven students conducted field studies in either Kenya or Costa Rica. Students worked in cognitive apprenticeships, in which research staff trained each student to conduct field research. At the conclusion of their fieldwork, the research staff assessed the students written field reports. The students' reports were then sorted according to the extent to which their studies were ecosystem-focused. Data analysis through nonparametric, Kruskal-Wallis statistical tests revealed no significant difference in academic performance on field study reports, in regards to whether the studies were narrow in scope (species-specific) or broad (ecosystem-focused). Marginal significance was revealed between ecosystem-focused studies and the potential for students' fieldwork to contribute to the advancement of science and conservation. Also addressed in the data were injuries, disease, and potential hazards, which were influenced by prudent and decisive leadership. Successful field studies require consideration of the content, context, and design of the intended field projects. Many of the solutions to environmental problems on the planet will come from the working hands of teachers and students that conduct explorations in the field. / Life Sciences in Education / D. Phil.

The purpose of this study was to investigate if teacher, pupil, curriculum and classroom environment variables were significantly related to adolescents' attitudes towards Biology. The study also investigated whether certain factors (as moderator variables) significantly influenced the relationships between pupils' attitudes towards Biology and each of the independent variables. For the investigation a sample of 426 standard eight, nine and ten pupils from three school-types completed an attitude questionnaire. Parametric statistics were used to analyse the results. Findings from the correlation and stepwise regression analysis revealed that the curriculum was the strongest correlate of attitude and accounted for most of the variance in pupils' attitudes towards Biology. An analysis of variance revealed no significant difference in pupils' attitudes towards Biology when gender, standard, parental levels of formal education and type of school were used as moderator variables. These findings suggest a complete restructuring of the Biology curriculum. / Psychology of Education / M. Ed. (Psychology of Education)

The purpose of this study was to evaluate the undergraduate biology practical instructions and the level of competence of undergraduate biology students in practical laboratory skills in some Ethiopian universities using skill performance rubric and questionnaires. A sample of 208 third year students and 26 instructors and laboratory assistants from three universities were selected as sample of the study. Students reported that more than 84.2% of the laboratory activities are below the average number of laboratory activities recommended by the curriculum with no significant difference between universities. The laboratory skill performance test score was below the midpoint. None of the students could be able to estimate and determine fields of vision of a microscope. There is a significant and a positively linear relationship between the students’ grade point average (GPA) with identification of laboratory equipment, handling of microscope, setting of microscope, estimation of diameter of field of vision and measuring liquid. Laboratory skill performance test score is correlated with higher education entrance exam score but not with students’ high school laboratory back ground. There is no significant difference in instructor’s manipulative skills among universities (p ≥ 0.09) and instructors manipulative skills is neither correlated with qualification nor teaching experience (P≥0.056). The most common method of assessment instructors’ use in the laboratory is laboratory report and identification of specimen examination (46.4%) and written exam and identification of specimen examination (35.7%). The number of courses having laboratory manuals is as low as 14.3%, in the new university. Manipulating materials, measuring and using numbers, and pre lab activity were common activities, and were found in every manual and in every university. Moreover, the result also revealed that the manuals contain high percentage rate of basic science process skills (75.4%) as compared to the integrated science process skills (24.6%). Correlation and multiple regression analyses revealed that students’ laboratory performance skills is significantly positively correlated with higher education entrance exam score, availability of laboratory resources and instructors experiences. Instructors’ experience has significant positive regression weights / Life and Consumer Sciences / D. Phil. (Mathematics, Science and Technology Education)

Thesis (MEd)--Stellenbosch University, 2013. / Bibliography / ENGLISH ABSTRACT: The focus of this study is on Biology teachers in selected Namibian schools. The researcher seeks to understand how Biology teachers implement Environmental Education (EE) as part of the Biology curriculum as is mandated in the curriculum policy. Literature indicates that the EE curriculum and the science curriculum are underpinned by different philosophical and pedagogical perspectives. This prompts the research questions, and the subsequent research reported on in this thesis. During a case study guided by a qualitative interpretive paradigm, Biology teachers and Biology advisory teachers are interviewed about their experiences and actions and invited to make suggestions. In addition curriculum document analysis and observation are used. The data point to the aspects that can facilitate the implementation of EE in the curriculum, However the implementation of EE is associated with many obstacles and challenges. Teachers struggle to implement EE because of an inadequate understanding of EE and its underlying philosophy. Further enhancement of EE will also require the reduction of tensions between policy and practice, logistic barriers, and the gap between EE and science, while increasing the involvement of teachers in curriculum development, collegiality among teachers and principals, teachers and advisory teachers’ knowledge of EE, teachers and advisory teachers’ curriculum understanding and professional support. Teachers cannot achieve the objectives of EE unaided; therefore the establishment of EE co-coordinators in schools is suggested, since schools have failed to implement EE without such support. In addition, it is suggested that activity systems be studied in totality and that boundaries be crossed to enrich the outcome of EE. . Subject advisors are mandated by the government to support teachers experiencing problems, and it is suggested that ideas linked to the activity systems and activity theory be investigated and implemented to solve the problems. This should improve the implementation of EE as part of science teaching in the schools where the study was conducted and in other schools. / AFRIKAANSE OPSOMMING: Die fokus van hierdie studie was op biologie-onderwysers in geselekteerde Namibiese skole. Die navorser probeer om te verstaan hoe biologie-onderwysers Environmental Education (EE) implementeer as deel van die biologie van die kurrikulum wat in die kurrikulum beleid mandaat. Literatuur dui daarop dat die EE kurrikulum en die wetenskap kurrikulum word ondersteun deur "anders" filosofiese en pedagogiese perspektiewe wat die navorsing vrae gevra, en die daaropvolgende projek berig in hierdie tesis. Het egter Biologie-onderwysers se pre-diens onderwys sluit nie EE. Tydens 'n gevallestudie gelei deur 'n kwalitatiewe interpretatiewe paradigma, is biologie-onderwysers en biologie raadgewende onderwysers ondervra oor hul ervarings, aksies en voorstelle. Kurrikulum dokumente is ontleed en waarnemings van onderwysers in klaskamers in Benewens onderhoude en dokument-analise is gebruik. Data dui daarop dat die implementering word omring deur baie struikelblokke en uitdagings. EE is beperk tot opvoeding oor die omgewing en word gelei deur wetenskapsfilosofie. Dit lyk asof daar 'n gebrek aan begrip van EE en sy onderliggende filosofie deur onderwysers. Die meeste onderwysers noem baie struikelblokke as struikelblokke tot die implementering en dit sluit in logistieke hindernisse, en die gaping tussen EE en wetenskap, 'n gebrek van die betrokkenheid van onderwysers in kurrikulumontwikkeling, 'n gebrek van kollegialiteit onder onderwysers en skoolhoofde, gebrek aan onderwysers en raadgewende onderwysers se kurrikulum begrip en professionele ondersteuning. Terwyl, dokument-analise het gewys op die spanning tussen beleid en praktyk. Verdere data wys na die aspekte wat kan ondersteun as die inlywing van EE in die kurrikulum EE implementering, Biologie word gesien as 'n goeie voertuig vir EE, onderwysers benaderings is kennis van leerder, onderwysers se houding teenoor die implementering is positief. Advisory onderwysers kennis van hul algemene verantwoordelikhede, maar hulle lyk nie te verstaan hoe dit is van toepassing in EE weens gebrek aan EE kennis. Onderwysers kan nie die doel bereik sonder hulp, dus die vestiging van EE mede-koördineerders in skole word voorgestel, aangesien skole het misluk EE te implementeer sonder ondersteuning. Daarbenewens word dit voorgestel dat die aktiwiteit stelsels in totaliteit bestudeer word en dat die grense oorgesteek om die uitkoms te verryk. In hierdie verband, vakadviseurs mandaat deur die regering om onderwysers te ondersteun wat hindernisse ervaar, en daar word voorgestel dat die idees gekoppel aan die aktiwiteit en aktiwiteit-teorie ondersoek word en geïmplementeer word om die hindernisse aan te pak. Dit moet EE implementering te verbeter as deel van die wetenskap-onderrig in die skole waar die studie gedoen is.

This study attempted to ascertain whether the under-representation of black, disadvantaged learners with cerebral palsy in biology and related careers is linked in any way to the method and content of teaching and learning in special education. In addition this study also attempted to identify and uncover the barriers that prevent learners with cerebral palsy from pursuing careers in science and technology related professions.

M.Ed. / Teaching and learning activity is characterised by effective communication. Teaching and learning as communication is successful when the learner has taken in new information with understanding. Effective teaching cannot take place unless effective communication takes place. On the other hand effective communication depends on media that are used in the teaching-learning activity (Heinich, et al, 1989: 13). In the teaching and learning of biology, educational media are important. The study of biology is a practical venture that requires the use of media e.g. realia, models, pictures and chemicals. Biology needs to be learnt through active participation, experience, observation and investigation by both the learner and the educator. This is not possible without the . use of media. In real life, the learner's senses are stimulated by media such as real objects, pictures, radio, television, books, etc. In the teaching of biology, the learner's senses must be equally stimulated. It is therefore necessary that the biology teacher be continuously reminded of the Chinese proverb which says, " I hear, and I forget; I see and I remember. I do, and I understand" (Dwyer, 1993: 194).
