  • Description: This thesis examines how meanings of masculinity and femininity are negotiated by South Africans on a social media platform linked to a popular local tabloid newspaper. In particular it explores conversations surrounding the Ben 10 phenomenon on the Daily Sun’s Facebook page. A Ben 10 is commonly understood as a young man who enters into a sexual relationship with an older woman, mostly in township settings, and readers engage vociferously over the meanings of such relationships. Using a constructivist understanding of gender, a thematic analysis is used to examine the Facebook comments on the Daily Sun’s most popular Ben 10 stories. South Africa’s constitution promotes the right to gender equality and freedom, which contributes to the normalisation of sex in public conversations and political debate. However, with high levels of unemployment and poverty in South Africa, the narrative of masculine success through work remains relatively unattainable. This tension between the narrative of male-bread winner through work and the reality of South Africa’s poverty and unemployment has been referred to as the crisis of masculinity. This thesis will argue that tabloids can play a strong political role by providing an alternative public sphere and that they can also assist their readers in coping with life in a democratic society by creating an imagined community of people sharing common experiences.

  • Description: South Africa’s freshwater resources are facing numerous water quality challenges and need to be protected from degradation and pollution by appropriate management strategies as they are a limited and shared resource. The South African Scoring System (SASS5), which assesses macroinvertebrate communities at family level, is used in routine monitoring of riverine ecosystems in South Africa. Assessing the condition of these ecosystems is limited as SASS5 does not allow for changes at lower levels of biological organisation to be detected. Fluctuating asymmetry (FA) - small random deviations from perfect symmetry - is considered a direct measure of developmental instability. This phenotypical response results from numerous internal and external factors and has a low level of heritability. FA is based on sound scientific principles, easy to measure, biologically robust and cost-effective. It reflects synergistic interactions between stressors and provides an integrated measure of several anthropogenic stresses, which strengthens the assertion that FA is an environmental indicator of water quality stress, and can potentially be used to detect stress in populations before irreversible effects manifest. FA responses were investigated by (1) exposing freshwater shrimp to increasing concentrations of cadmium chloride in a long-term experiment and (2) comparing FA responses to water quality changes and macroinvertebrate community responses in two case studies (Kwazulu-Natal and Limpopo Province) in South Africa. Although no consistent concentration-response curve could be established, this study suggests that FA responses can be used as a sublethal endpoint in exposure experiments. Determining water quality parameters causing FA responses was not possible in field collected freshwater shrimp in either case study. Although FA did not specifically respond to any of the measured water quality parameters identified in the case studies, it has potential as a general indicator of water quality stress in freshwater shrimp. This study shows that FA responses are potentially more sensitive than macroinvertebrate community responses to pollution since it is not affected by habitat. Since FA has the potential to be a general indicator of population quality, particularly where there are natural habitat differences, it can be useful at the level of biomonitoring required for routine basic river status assessments in South Africa. However, in order for FA to become a robust tool that can be used routinely in conjunction with SASS5 more research is required.

  • Description: This treatise will be focused on the design of a Mixed-use Facility in Mauritius, which will be implemented within an existing fishing village, Grand Gaube, located along the Northern coast of the Island. This site has been chosen due to its high fishermen population relying on fishing for their livelihoods. The proposed design will be aimed at a sustainable fishery which will involve the development of offshore bank fishing as opposed to the traditional lagoon fishing. With a focus on promoting a better catch quantity and quality, the increase in domestic production will be aimed at supplying the local market whereby a significant demand for seafood exists. In the process, the project will aim to alleviate poverty for the local fishermen communities through increased trade and job creations, while being in line with the Government’s vision for the development of the fisheries sector in Mauritius. The facility will include a Fish Landing Terminal, a Fish Processing Plant, and a Fish Market, for the production of a branded local product while accommodating the fishermen’s daily activities, as well as a highly public platform to create an activated public environment. In doing so, the proposed architectural intervention will act as a catalyst for urban and social change.

  • Description: DNAJC3 is a novel member of the DNAJ family with two domains linked to co-chaperone functions, namely the tetratricopeptide repeat (TPR) and J domain. Out of the two domains, the TPR domains are the least characterized. Therefore, the aim of this study was to characterize and elucidate additional functions of DNAJC3 TPR domains through in silico, in vitro and ex vivo approaches. Through multiple sequence and structural alignment as well as electrostatic potential analysis, DNAJC3 TPR domain were found to be most similar to TPR-containing proteins with Hsp90 or Hsp70 independent functions. In vitro pull down assays illustrated that DNAJC3 TPR domains did not interact with either cytosolic Hsp90 and Hsp70 or Grp78 and Grp94 directly, however a potential indirect interaction with Grp94 and Hsp90 was observed in mammalian lysates, via pull down assays; suggesting the formation of a complex between the proteins mediated by a specific substrate. DNAJC3 TPR domains were found to bind indiscriminately to both native and heat denatured substrates in a dose dependent manner. DNAJC3 TPR domains bound to β-galactosidase with greater affinity than malate dehydrogenase (MDH), suggesting that DNAJC3 TPR domains might exhibit substrate specificity that has not been reported before. Preliminary ex vivo analysis of DNAJC3 in mammalian cells showed that induced stress conditions did not alter the cytosolic or endoplasmic reticulum (ER) localization, or levels of DNAJC3 protein, suggesting that the protein is not stress inducible. However, protein levels of DNAJC3 were dramatically reduced by Hsp90 inhibitor novobiocin at 500 μM. Transient knockdown DNAJC3 did not change the protein levels of either Grp78 or Grp94, but decreased the protein levels of Hsp70/Hsp90 organizing protein HOP. On the other hand, protein levels of DNAJC3 were increased in HOP depleted cells. In conclusion, this study was the first to experimentally demonstrate that DNAJC3 TPR domains do not interact directly with Hsp90, Hsp70, Grp78 or Grp94, and therefore DNAJC3 is unlikely to participate in traditional co-chaperone interactions with those proteins via its TPR domain. However, the J domain is known to interact with Grp78. The discovery that DNAJC3 TPR domains resemble that of TPR-containing proteins with functions independent of Hsp90 or Hsp70 suggests that DNAJC3 might link the Hsp70/Grp78 chaperone machinery to non co-chaperone related functions, which requires further analysis.

  • Description: This study sought to do an overview and the role of Public Administration both as an academic discipline and as a discipline in practice. It sought to do a literature analysis of the macroeconomic policies and strategies that the democratic from 1994- 2012 particularly with regards to lowering unemployment and meeting public needs. The literature review on the Freedom Charter and the South African democratic government’s macroeconomic policies namely the RDP, GEAR, ASGISA, New Growth Plan, and the National Development Plan were studied in great detail in this study. Public Finance in terms of the tax revenues collected and public debt servicing costs have contributed to the capacity of the SA government to meet its public needs and social needs including poverty eradication. It identified that the NDP because of its longer term plan approach its goals could be realizable. It identified that the South African democratic government macroeconomic policy has been consistent since 1994 that of belt tightening or fiscal policy that is tight on fiscal spending and monetary policy also has remained the same although different names have been used over the period 1994-2012. The South African democratic government since 1994 has been pursuing austere fiscal policy. This is because it inherited a government that had high public debt and therefore had to prioritise of servicing that debt. That meant that there has been less funds available to spend on public needs as the aspirations of the people when they drafted and adopted in a congress of the ANC the freedom charter in 1955. The South African democratic government through its macroeconomic policy has created a number of positive changes in the country economically and socially that have benefited a lot of the previously marginalized people of South Africa however the macroeconomic objectives of reducing unemployment, growing the economy, increasing exports and lowering inflation still remain a huge challenge in this country. This study concludes that in order to increase revenues to meet public needs government needs to look at increasing its revenue base rather than borrowing the money as that will create the same challenge that it is currently facing hence it adopted the austere fiscal policy.

  • Description: One of the purposes of the Namibian curriculum is to ensure cultural inclusivity. That is, it recognises the inclusion of traditional cultural practices and experiences in science lessons where appropriate. Based on my experiences both as a learner and a science teacher, I have noted there is a rapid decline and loss of values in most of our cultural practices and heritages. This triggered my interests to do a study on an Oshiwambo traditional beverage known as Ombike. This study is therefore aimed at enhancing conceptual development, meaning making and understanding of concepts in fermentation and distillation. This study was conducted with my grade 9 learners at a school where I was teaching in Omusati region of Namibia. A community member who served as an expert was also a participant. She was involved more in discussions, interviews and most importantly in showing and demonstrating to the learners how Ombike is made practically. Essentially, the goal of this study was to investigate how the indigenous practice associated with the making of Ombike can be used to support meaning making of fermentation and distillation processes. This research is located within an interpretive paradigm where a qualitative case study was adopted. I consider this methodological framework appropriate in this study because it allowed me to use the following data gathering methods: brainstorming and discussion, observation, semi-structured and focus group interviews, and practical activities worksheet. Multiple methods were used for the purpose of triangulation and validation. An inductive analysis was used to discover data patterns and themes from the data. Moreover, ethical considerations were also taken seriously and all the participants gave informed consent. The findings of the study revealed that brainstorming and discussions were an appropriate strategy in eliciting learners’ prior everyday knowledge and experiences on, in particular, the making of Ombike. Furthermore, learner engagement and conceptual development were enhanced. This suggests that contextualisation of knowledge can enhance meaningful learning if it is properly planned. It was also found that practical activities in conjunction with mind maps helped learners to make meanings of scientific concepts. Based on my research findings, I therefore recommend the following three aspects: the consideration of learners` prior knowledge and experiences; contextualising knowledge through use of indigenous knowledge; and the learners’ active involvement in practical activities with an emphasis on key scientific concepts to be developed. That is, there is a need to teach for conceptual understanding.

  • Description: This thesis presents the development of chlorophyll, cholic acid, aflatoxin B1 molecularly imprinted polymer (MIP) particles and cholic acid MIP nanofibers for application as selective solid phase extraction (SPE) sorbents. The particles were prepared by bulk polymerization and the nanofibers by a novel approach combining molecular imprinting and electrospinning technology. The AFB1 MIP particles were compared with an aflatoxin specific immunoextraction sorbent in cleaning-up and pre-concentrating aflatoxins from nut extracts. They both recorded high extraction efficiencies (EEs) of > 97 % in selectively extracting the aflatoxins (AFB1, AFB2, AFG1 and AFG2). High reproducibility marked by the low %RSDs of < 1% and low LODs of ≤ 0.02 ng/g were calculated in all cases. The LODs were within the monitoring requirements of the European Commission. The results were validated with a peanut butter certified reference material. The chlorophyll MIP on the other hand selectively removed chlorophyll that would otherwise interfere during pesticide residue analysis (PRA) from > 0.6 to <0.09 Au in green plants extracts. The extracted chlorophyll was removed to far below the level of ≥ 0.399 Au that is usually associated with interference during PRA. Furthermore, the MIP demonstrated better selectivity by removing only chlorophyll (> 99%) in the presence of planar pesticides than the currently employed graphitized carbon black (GCB) that removed both the chlorophyll (> 88%) and planar pesticides (> 89%). For the interfering cholic acid during drug residue analysis, cholic acid MIP electrospun nanofibers demonstrated to be more sensitive and possessing higher loading capacity than the MIP particles. 100% cholic acid was removed by the nanofibers from standard solutions relative to 80% by the particles. This showed that the nanofibers have better performance than the micro particles and as such have potential to replace the particle based SPE sorbents that are currently in use. All the templates were optimally removed from the prepared MIPs by employing a novel pressurized hot water extraction template removal method that was used for the first time in this thesis. The method employed only water, an environmentally friendly solvent to remove templates to ≥ 99.6% with template residual bleeding of ≤ 0.02%.

  • Description: In this thesis we study left-invariant control offine systems on the symmetry group of a. model of hyperbolic plane geometry, the matrix Lie group SO(1, 2)₀. We determine that there are 10 distinct classes of such control systems and for typical elements of two of these classes we provide solutions of the left-invariant optimal wntrol problem with quauratic costs. Under the identification of the Lie allgebra .so(l, 2) with Minkowski spacetime R¹̕'², we construct a controllabilility criterion for all left-invariant control affine systems on 50(1. 2)₀ which in the inhomogeneous case depends only on the presence or absence of an element in the image of the system's trace in R¹̕ ²which is identifiable using the inner product. For the solutions of both the optimal control problems, we provide explicit expressions in terms of Jacobi elliptic functions for the solutions of the reduced extremal equations and determine the nonlinear stability of the equilibrium points.

  • Description: Cajanus cajan (L.) Millsp. (Pigeonpea) belongs to the Leguminosae genus Cajanus which is composed of 34 species. Pigeonpea is the only cultivated member of the genus, while the remaining species are wild relatives belonging mainly to the secondary gene pool. DNA sequence data from the nuclear ITS region and the chloroplast trnL-F spacer were utilized to investigate the phylogenetic relationships between Cajanus and five other allied genera in the subtribe Cajaninae. This study revealed the non-monophyly of Cajanus and Rhynchosia and supported the monophyly of Eriosema and Flemingia, but more sampling ,especially from the large genera of Rhynchosia and Eriosema, is recommend to adequately test the hypothesis of generic monophyly. The phylogenetic relationships within the genus Cajanus resolved Cajanus scarabaeoides (L.) Thouars as the most basal species in the Cajanus clade. The study also utilized Single Nucleotide Polymorphism (SNP) markers derived from low copy orthologous genes and genotyped using the high throughput SNP-OPA Illumina golden gate assay. The aim was to understand phylogenetic and domestication history, genetic structure, patterns of genetic diversity, gene flow and historical hybridization between Cajanus cajan (pigeonpea) and wild relatives. The neighbor-joining tree resolved well-supported clusters, which reflect the distinctiveness of species and congruence with their geographical origin. It supported the ITS based phylogeny and resolved C. scarabaeoides as basal to the Cajanus clade. The phylogenetic signal and genetic signatures revealed insights into the domestication history of pigeonpea. Our results supported Cajanus cajanifolius as the presumed progenitor of pigeonpea and we speculate that for pigeonpea there was a single major domestication event in India. Genetic admixture and historical hybridization were evident between pigeonpea and wild relatives. Abundant allelic variation and genetic diversity was found in the wild relatives, with the exception of wild species from Australia, as compared to the domesticated pigeonpea. There was a reduction of about 75% in genetic polymorphism in domesticated pigeonpea as compared to the wild relatives, indicating a severe “domestication bottleneck” during pigeonpea domestication. We discovered SNP markers associated with disease resistance (NBS-LRR) loci. The SNPs were mined in a comparison of BAC-end sequences (BES) of C. cajan and amplicons of the wild species, C. scarabaeoides. A total of ~3000 SNPs were identified from 304 BES. These SNPs could potentially be used in constructing a genetic map and for marker assisted breeding.

  • Description: This thesis examines the development of Grahamstown from its inception in 1812 to the mid-1840s, paying particular attention to the social and cultural life of the town. It traces the economic development of the town from a military outpost to a thriving commercial settlement, noting the essential factor of the town's proximity to the Cape frontier in this process. The economic interaction between diverse groups in the town mirrors the social and cultural interaction which occurred between British settlers, Khoekhoe and Africans. The result of these interactions was the creation of a new, distinctively South African urban society and culture, despite the desire of the white settlers to reproduce a “typical” English environment in their new home. The conflict between attempts to anglicise the urban environment and the realities of Grahamstown's situation on a colonial frontier was reflected in the architecture and layout of the town. Attempts to recreate an English social environment also failed. New classes arose in the town in response to the economic opportunities available on the frontier. Although some settlers prospered, many did not, and the presence of an impoverished white working class undermines settler historians' picture of settler success and affluence. The poorest people in the town, though, were the increasing numbers of Khoekhoe and Africans who migrated from the surrounding countryside, and who were unequally incorporated into the urban community as a colonial labouring class. In response to these unique circumstances, white settlers in Grahamstown developed a powerful political and propaganda machine, which helped lay the foundations of a distinct settler identity in the eastern Cape.

  • Description: In this study I investigated the effect of a science literacy strategy on the development of grade six and seven second-language learners’ general literacy skills in both their home language (isiXhosa) and language of instruction (English). The scientific literacy strategy used focuses on reading to learn science, writing to learn science, classroom discussion and argumentation. A mixed method design was used. Quantitative data were collected from baseline and post-testing of language skills of learners. Qualitative measures were generated through interviews of learners and teachers and classroom observations. The sample comprised of seven grades six and seven (multigrade classrooms) classes in seven primary schools situated in the rural areas near Hogsback in the Eastern Cape (five experimental schools and two control schools). Mean differences between the experimental and control groups for the reading, listening, writing and speaking aspects of the literacy tests were computed and the data generated were treated statistically using Analysis of Variance. The qualitative data were used to gain deeper insights into the quantitative results. The data suggest that the science literacy strategy statistically significantly improved the learners reading skills in English, their listening skills in both English and isiXhosa, and their writing skills in isiXhosa over a six-month period. Possible explanations for these results are that the reading material was in English only, extensive use of code-switching from English to Xhosa was made by the teachers while teaching, and that learner classroom discussion and writing in isiXhosa was encouraged.

  • Description: The tourism industry has been identified as the industry with the most potential to create jobs and contribute largely to economic growth. In order to live up to this potential, tourism businesses need to create tourism products for potential tourists which need to be promoted successfully through a number of mediums. The use of the Internet as a medium for promoting and selling tourism products is increasing, however, in order for tourism businesses to successfully promote the tourism product through the Internet, they have to understand the needs and wants of their current and potential target markets. One segment of the tourism market that has come under increasing attention is the mature traveller market. This market is defined as travellers who are 50 years of age and older. Generally, the mature traveller market is viewed as a small homogenous group of old consumers with little or no spending power. However, evidence suggests that this market is comprised of an increasing number of diverse people, who use the Internet and like to spend on tourism products. Therefore, this research will examine differences between Internet users and Internet non-users in the mature traveller market. Specific attention will be paid to investigate differences in demographic, socioeconomic, Internet use and travel-related characteristics. The identification of these characteristics will enable a profile to be d~veloped for each group, which can be used by tourism businesses to effectively promote tourism products over the Internet to the mature market In order to collect data from potential respondents, a questionnaire which was used in a similar study conducted in the US was used. Data was collected using a convenience sample of Internet users and Internet non-users from the Eastern Cape and Gauteng provinces of South Africa. Cronbach alpha and factor analysis were used to assess the reliability and validity of the research instrument and measurement scales. In order to test whether differences did exist between the two groups the Chi-square and t-test statistics were used. Finally in order to examine which factors where influential in differentiating between Internet users and Internet non-users discriminant analysis was employed. The findings in the present study suggest that there are significant differences in demographics, socioeconomic, Internet use and travel-related characteristics between Internet users and Internet non-users in the mature market. By understanding the differences between Internet users and Internet non-users, tourism businesses can identify marketing strategies that appeal to mature travellers who use the Internet and to those do not, by utilising information gathered from Internet users and Internet non-users demographic, socio-economic and travel-related characteristics.

  • Description: Educational transformation and curriculum reform within the new South African Outcomes Based Education (OBE) system has introduced new roles for teachers, and a focus on environmental learning within each learning area. In an OBE system, teachers are required to mediate learning, develop learning programmes, and use a range of different learning support materials. This study aimed to explore how one teacher in an Eastern Cape school used environmental learning support materials to mediate learning within an OBE curriculum framework. Over the past ten years a number of environmental educators and researchers have been participating in curriculum policy development and curriculum implementation research. This has led to the incorporation of an environmental focus within different learning areas in Curriculum 2005. The focus on environment in the curriculum was strengthened by the introduction of the National Environmental Education Project in the General Education and Training (NEEP-GET) band in 2001. I am employed as a provincial co-coordinator within this project (for the Eastern Cape province), and one of my tasks is to work with service providers (who provide learning support materials) and teachers (who use these materials) to ensure improved environmental learning within the OBE curriculum. A qualitative and empirical case study was conducted in which I observed one teacher in a multi-grade class (with grade 6 and 7 learners) using learning support materials to achieve learning outcomes in three different lessons. The study employed a range of data collection methods such as questionnaires, interviews, field notes, video recording, and document analysis, photographs and journal entries. I compiled a contextual profile of the school and classroom and undertook two 'layers' of data analysis to report the findings of the study. This research indicates that theories of learning and associated teaching methods influence learning interactions, and the use of learning support material in the class. The study also highlighted emerging issues in the use of environmental learning support materials, which relate to planning; access to materials; over-use of materials; and the relationship between learning support materials and teaching methods.

  • Description: Phenomenological models are presented which predicts transpiration rates (E) of individual leaves of Scaevola plumieri, an indigenous dune pioneer, and Ammophila arenaria, an exotic grass species introduced to stabilise mobile sand. In both cases E is predictably related to atmospheric vapour pressure deficit (VPD). VPD is calculated from measurements of ambient temperature and humidity, hence, where these two environmental variables are known, E can be calculated. Possible physiological reasons for the relationships of E to VPD in both species are discussed. Scaling from measurements of E at the leaf level to the canopy level is achieved by summing the leaf area of the canopy in question. E is predicted for the entire canopy leaf area by extrapolation to this larger leaf area. Predicted transpiration rates of individual shoot within the canopy were tested gravimetrically and shown to be accurate in the case of S. plumieri, but less so in the case of A. arenaria. Using this model, the amount of water used by a known area of sand dune is shown to be less than the rainfall input in the case of S. plumieri in wet and dry years. The water use of A. arenaria exceeds rainfall in the low-rainfall year of 1995, while in 1998 rainfall input is slightly higher than water extraction by the plants. Using a geographic information system (GIS), regional maps (surfaces) of transpiration were calculated from surfaces of mean monthly temperature and mean monthly relative humidity. Monthly surfaces of transpiration were subtracted from the monthly median rainfall to produce a surface of mean monthly water deficit. Areas of water surpluses along the coast correspond with the recorded distribution of both species in the seasons that the plants are most actively growing and reproducing. This suggests that unfavourable water availability during these two species growth periods limit their distributions along the coast. In addition to unfavourable water deficits, additional climatic variables that may be important in limiting the distribution of these two species were investigated using a discriminant function analysis.

  • Description: The purpose of this study was to investigate whether the space provided by a readerresponse transaction between girls and the text, Roll of Thunder, Hear My Cry (Taylor 1977) .. empowered pupils to tell their own stories. It also sought to identify ways in which the problems and possibilities perceived by these pupils might guide curriculum decisions in a transforming education system. In addition to engaging in reader-response activities around the text, drama and videos providing social context were integral to the programme. Related work in the subject areas of history and lifeskills was also undertaken. Data was drawn from pupils' reading journals, responses to specific passages, transcripts of small group discussions, and interviews. The study is ethnographic in nature and all the data qualitative. Theoretical insights were drawn from the felds of cultural studies, postmodern criticism, and postructural modes of cultural and social analysis inasfar as they illuminate and inform the relationship between language, knowledge and power. The research was conducted in an historically white, girls' school which adopted a nonracial admissions policy in January 1991. Despite the fact that existing traditions and values of the the school to a very large extent influence what is taught, the data suggests that pupils were becoming agents in their own learning and were taking up multiple identities both within and without the world of the school.

Personal growth through classroom English : (What pupils say they get out of English teaching)

  • Description: Guidance and counselling aims to promote the personal growth of the adolescent. However, in the current South African context, it is possible that formalised Guidance instruction and the post of the school counsellor may disappear in many schools as a result of economic rationalisation. If this occurs, the fostering of personal growth will rest with all teachers and it will be vital to utilise all available opportunities. The study of English is one of the areas traditionally seen to promote personal growth, as several aims of English teaching relate to such growth. The purpose of this study is to investigate from the pupil's perspective whether these aims are being fulfilled within 'Model C' CEO schools in order to gauge the potential of English teaching to fulfil the personal growth role of Guidance teaching. Pupils were asked what influence English teaching had on their attitudes and ideas towards life, on themselves and on their development as people. From the data, common themes were established and documented. These themes showed that important aspects of personal growth are indeed fostered by the English teaching of literature, poetry, written work, oral work and visual literacy. This study therefore confirms that English teaching does foster personal growth and that the potential does exist for English teaching to subsume some of the roles of Guidance.

A pilot study of the relationship between the English language abilities of a group of primary school children and their tree-drawings

  • Description: This pilot study attempts to assess the correlation between language ability and a projective Tree-drawing test. The hypothesis tested is that expounded by Sandra Michel, a psychologist working with Dr. A. A. Tomatis at the Language Centre in Paris. The theory of Language from which her work derives is that put forward by A. A. Tomatis in Vers l'écoute humaine (Towards Human Hearing), (1977) and Education and Dyslexia trans . , Louise Guiney, (1972). This hypothesis states that the Tree-drawing can give a clear indication of the kind of dialogue the testee will be able and willing to use. The claims for projective Tree-drawing 'tests' or techniques have been mainly concerned with personality or psychological assessments and sometimes with intelligence testing since Charles Koch first began his work in this field in the early forties. Sandra Michel in "The Tree Test", translated by T . Brown, (unpublished paper), Tomatis Centre (Scarbrough, Ontario, 1980) discusses a Tree-drawing scale that indicates both the developmental level of the child's language ability and his/her motivation towards dialogue and communication at this level. To test this hypothesis a sample of 1094 Tree-drawings was used. The drawings were done by Primary School children of both sexes from Sub. A. to Std . 5, collected over four years of research. These drawings were studied to see if the Tree scale of drawings described by Michel did in fact occur and if they occurred in the sequence she suggests. As a result of these preliminary investigations a developmental scale was devised and proposed as a refinement of Michel's scale. Scores from these two Tree-scales were correlated with English language scores using Pearson Product Moment Correlation Coefficient and the Spearman Rank techniques. The sample for this correlation study was a group of 54 Std. 5 pupils whose English language ability was evaluated by (i) a school English Examination mark, (ii) a Questionnaire scoring receptive and expressive language behaviours and (iii) Verbal I.Q. scores. The positive correlation between these language scores and the Tree-drawing projective test scores are discussed and the implications for English language teaching and suggestions for further research mentioned.

Evaluating an English department: the use of illuminative evaluation procedures in descriptive and diagnostic analysis of English teaching programmes in high schools

  • Description: To evaluate what is actually happening within a High School subject curriculum, the annual parade of marks, percentages and symbol distributions is not by itself adequate, especially in assessing progress towards such English syllabus goals as: That pupils expand their experience of life, gain empathetic understanding of people and develop moral awareness. (3.1. 4 HG) How too, from examination results alone, can a subject head of English assess the success of his objective "to woo his pupils into the reading habit"? (School 1: Goals 1988) Decisions on English department policy and procedures are frequently based on personal hunches and examination results. Few subject departments engage in proper evaluations of their curricula to support decisions made, or to impart meaning upon the countless daily transactions between child and adult, individual and institution in the learning process. This study demonstrates the efficacy of "illuminative evaluation" techniques in opening out an educational innovation (1986 First Language English syllabi of the Cape Education Department) at two High Schools for comment and appraisal. The array of information gathered should be useful in planning and implementing further curricula initiatives. The inherent flexibility of illuminative evaluation procedures and their freedom from large-scale data base requirements needed for 'scientific' models of evaluation are advantageous in investigating the untidy complexities of English teaching. Both 'closed' and 'open' response questionnaires, interviews, and perusal of relevant documents informed the researcher of the views of pupils, parents, English teachers, other subject heads, the two school principals and the education authorities on what waS and ought to be happening in English classes. From the considerable array of information generated, the distress of conscientious English teachers facing unreasonable work-loads emerged clearly. Such teachers are likely to occupy key roles in the non-racial state schools of the future and cannot be regarded as expendable. 'Open schools' present new challenges to existing curricula and the position of English may prove to be critical. Thus it is submitted that English subject heads should be concerned with evaluating their departments so that informed decisions can be taken on future directions. Illuminative evaluation is demonstrably useful in such analyses.
