- Description: This study examines the small group work management techniques of a teacher of English in a second language classroom in Bophuthatswana. The school at which the observation takes place, is a black secondary school in Mmabatho which follows the Department of Education and Training (DET) syllabus and writes the DET external matriculation examination. The goal of the research is to assess and evaluate the methods the teacher uses in managing group work according to five specified areas. These areas are noted for their importance in the successful management of group work. The report on the findings of this research reveals that the teacher's understanding of the nature of small group work differs from the accepted characteristics of successful group work management as interpreted by authorities in this field. This gives rise to management techniques that are sometimes inappropriate and ill-considered. Although this study observes only one teacher, the findings indicate the need for more classroom-based research in order to establish the true nature of classroom practice. Assumptions about classroom practice are too readily made by innovators, syllabus designers and textbook writers who design materials based on methodologies which can be complex and difficult to implement. These methodologies require understanding and commitment from the teacher. However, the pre-service and in-service education and development that the teacher receives often does not guarantee understanding of the processes involved nor does it generate the necessary commitment to small group work as an effective teaching technique.

- Description: The demand for innovative end users of information technology is increasing along with the proliferation of computer equipment within the workplace. This has resulted in increasing demands being made upon educational institutions responsible for the education of computer end users. The demands placed upon the teachers are particularly high. Large class groups and limited physical resources make the task especially difficult. One of the most time consuming, yet important, tasks is that of student evaluation. To effectively assess the practical work of information technology students requires intensive study of the storage media upon which the students'efforts have been saved. The purpose of this study was to assess the suitability of criterion-referenced testing techniques applied to the evaluation of end user computing students. Objective questions were administered to the students using Question Mark, a computer-managed test delivery system which enabled quick and efficient management of scoring and data manipulation for empirical analysis. The study was limited to the classroom situation and the assessment of primary spreadsheet skills. In order to operate within these boundaries, empirical techniques were used which enabled the timeous analysis of the students' test results. The findings of this study proved to be encouraging. Computer-mediated criterion-referenced testing techniques were found to be sufficiently reliable for classroom practice when used to assess primary spreadsheet skills. The validation of the assessment technique proved to be problematic because of the constraints imposed by normal classroom practice as well as the lack of an established methodology for evaluating spreadsheet skills. However, sufficient evidence was obtained to warrant further research aimed at assessing the use of computer-mediated criterion-referenced tests to evaluate information technology end user learning in situations beyond the boundaries of the classroom, such as a national certification examination.

A combination of a stationary and non-stationary model to predict corporate failure in South Africa

- Description: Business failure should be of concern in most industralised countries and the importance of accurately evaluating the phenomenon from a management and investment point of view is enormous. Were it possible to predict failure with a certain degree of confidence, steps could be taken to rectify the situation and the benefit would accrue to all of the stakeholders in the macroenvironment. In essence, the profitability of a business is influenced by two sets of variables. In the first instance, it is influenced by a variety of internal (microeconomic) variables which are firm- specific and which management is generally able to control. A further distinction in this regard may be made between the financial and non-financial variables. In the second instance, it is generally accepted that profitability will be influenced by a number of external (macroeconomic) variables which are generally beyond the control of management. In the main, however, the profitability of the firm is generally determined by a combination of both sets of factors. To date, a great deal of research has been undertaken in an attempt to establish a reliable model which may be used to predict failure. This has mainly been confined to the microeconomic variables which can be used to predict failure and attempts have been made to isolate either a single financial ratio or a number of financial and non-financial variables which can be used to model corporate failure. The research has met with a certain degree of success although this appears to be confined to the economic environment to which the models have been applied. The models are less successful when applied to other macroenvironments. Limited research has been undertaken into the macroeconomic variables which contribute to business failure or to a combination of the two types of variables. It is appropriate therefore that further consideration be given to the establishment of a model incorporating ALL the variables which could contribute to corporate failure. The purpose of this research is to undertake an investigation of micro- and macroeconomic variables that are freely available to reserachers and which may be used in a failure prediction model. The intention is to obtain a comprehensive, yet simple model which can be used as an overall predictor of PENDING failure.

- Description: This thesis focuses on the articulation in music of human worldviews, and the social contexts in which they emerge. It suggests that people project various forms of social reality through symbolic systems which operate dynamically to maintain and recreate cultural patterns. The symbolic system investigated in support of this suggestion is that constituted by Venda guitar songs. In the performance of these songs, social reality emerges in a combination of symbolic forms: verbal, musical and somatic. The combination of these symbolic forms serves as a medium for individual self-awareness basic to the establishment of social reality and identity, and the drive for social power and legitimacy. A study of these symbolic forms and their performance indicates that musicians invoke the potential of communal music to increase social support for certain principles on which survival strategies in a turbulently changing society might be based. The discourse of Venda guitar songs incorporates modes of popular expression and consciousness, and thus attempts to invoke states of intensified emotion to promote these survival strategies. Performance occasions emerge as a focus for community orientation and the exploration of social networks. They promote stabilizing social and economic interaction, and serve as a basis for moral and cooperative action. Social reality also emerges in musical style, which is treated as the audible articulation of human thought and emotion. Stylistic choices are treated as integral to the conceptualization of contemporary existence. A study of these choices reveals varying degrees of cultural resistance and assimilation, ranging from musical styles which are essentially rooted in traditional social patterns, to styles which integrate traditional and adopted musical elements as articulations of changing self-perceptions, social aspirations, and quests for new social identity.

Our members don't want the crumbs off the table. No, they want to be given the opportunity to participate fully in the economy and in particular in the development of the fishing industry. The industry is, however, still trapped in the past. As a result it cannot make use of the many opportunities we believe there are for it to expand and grow. Before I examine these opportunities perhaps it is wise to set out briefly the principles on which we see the industry established.

- Description: The sexual abuse of children has become recognised as a major problem affecting children in most, if not all, countries of the world. The prevention of such abuse has, in the last decade, become an issue of international significance. In South Africa, prevention efforts are mainly informal ad hoc strategies initiated by individuals or organisations. As such they suffer from being short-lived and often isolated. Prevention efforts fall into the general categories of primary, secondary and tertiary prevention. Primary prevention focuses on preventing abuse from occurring at all. There are two main aspects to this type of prevention. The first aims at teaching children to protect themselves. The second aims at preventing the development of a disposition to abuse. This study set out to suggest and justify the adoption of a national strategy appropriate to the South African situation, including an overview of what can be done through the schooling system. This strategy will provide a framework and context for individual efforts, and hopefully stimulate new programmes. In addition, a detailed prevention programme for implementation in the secondary school, through the medium of the subject Guidance, was developed. This programme addressed itself mainly to that primary aspect of prevention concerned with preventing people from developing a disposition to abuse. The programme consists of lesson plans, teacher's notes and worksheet materials for pupils.

- Description: Preface: An awareness of certain contradictory perceptions and assumptions regarding religious beliefs today and their relevance to art prompted a question which led to the research undertaken in this minithesis. The question was: how significant is the absence or presence of religious beliefs to the modern creative process? The writings of some theologians, sociologists, psychologists, and anthropologists seem to indicate that religious beliefs are fundamental to the functioning of society and the individuals who are part of it. Furthermore, even a cursory study of the history of art will demonstrate the strong bond between pre-nineteenth century image making and organised religion. Today, however, this relationship appears uncertain or even non-cxistant. This is a result of processes which began to gain strength in the nineteenth century: these include the industrial revolution, scientism and materialism. Peter Fuller, stated that among the most central questions affecting art is, "the severance of the arts from religious tradition and their existence within an increasingly secular culture." (Fuller, 1990, p. 189). This statement appears to bring the issues together very neatly. Firstly there is the assertion that religion has nourished and been a vital force behind art through the ages, and that, modern art has lost this source of vitality. Secondly, there is the contention tbat society, since the nineteenth century, has become increasingly secular, and that this has had (and is having) a radical effect on modern art. That art has been divorced from religion and that religion is disappearing, or will do so, is the logical conclusion, according to theorists who insist on institutional religion as the only true form. Some artists, for whom the absence or presence or loss of religious beliefs are important issues, may in this situation experience a creative crisis. In order to address these issues it was necessary to investigate whether religious beliefs are important to artistic endeavour and, if so, what the consequences of the absence of beliefs might be. For this reason, research into the nature of religion and the modem religious situation was initiated. The purpose of the extensive discussion on the nature of religion was to establish definitions of, or a view of, religion which could provide a sound basis for this investigation of the issues that have been outlined. In order to demonstrate whether religious beliefs are important to the creative process, Francis Bacon was chosen for discussion because he appeared to be a modern artist who had no religious beliefs and was thus an ideal example by which the consequences of this could be gauged.

- Description: The considerable volume of chromium-bearing wastes generated during the process of leather tanning, exacerbated by the potential for trivalent chromium in the wastes to be oxidised to the toxic hexavalent state, has created a major waste disposal dilemma for the tanning industry. While methods are available for the safe and effective treatment of residual chrome-tanning liquors, little has been done to address the issue of the chrome-bearing solid wastes. Given the increasingly stringent environmental compliance standards facing tanneries, unless an appropriate treatment process is developed in the immediate future, the continued use of chromium as a tanning agent could be compromised. Recent investigations have demonstrated the potential of heated alkaline conditions for dechroming these solid wastes. This study expanded upon these considerations and examined the feasibility of utilising the highly alkaline tannery waste effluents as cost-effective, substitute alkaline media. The three effluents considered in this study, classed as lime sulphide liquors, were shown to be capable of dechroming wet blue shavings, with resultant separation of the solid wastes into a protein and a concentrated chromium product. The solubilised protein product contained low chromium concentrations which comply with legal discharge limits. The precipitated chromium product offers opportunity for reutilisation in the tannery. A novel industrial-scale treatment process, based on these investigations, indicated the process to be capable of treating the quantity of shavings produced on a daily basis by a medium to large scale tannery. Application of this method for the dechroming of other chrome-tanned solid wastes was also shown to be feasible.

- Description: A growing number of primary schools are acquiring computers, mainly through parent funding. The study concerns the promotion of computer use across the curriculum in primary schools. Teachers need to be trained in the use of computers as a teaching aid in different subjects. A study comparing two periods of training was undertaken. Two model C primary schools, administered by the Department of Education and Culture, with similar profiles of educational computer use, were selected for the purpose. A training course consisting of five sections, where the use of the word processor, spreadsheet and database, both as personal tools and as teaching aids were introduced, was offered. Care was taken to select topics from current syllabi and to demonstrate how these topics could be presented and enhanced by using the computer. The training was presented at school A over a period of 8 months and at school B over a period of 5 weeks. The supporting material and contents of the course were the same for both groups. A comparison between the effectiveness of the two training regimes was made. The researcher's initial perceptions of the teachers' initial low level of computer literacy were confirmed by a questionnaire, responded to by each participant. It would seem that the shorter raining period was more effective in raising the level of computer literacy and that if the training period was longer, the contact time should be increased to maintain support. Neither training period resulted in a significant increase in computer use, either as a personal tool or as a teaching aid. The failure to do so may be ascribed to a number of influences, one of which is the teaching style of individual teachers. Changing the teaching style of an experienced teacher takes time and more effort than was available for either training period.

The training was presented at school A over a period of 8 months and at school B over a period of 5 weeks. The supporting material and contents of the course were the same for both groups. A comparison between the effectiveness of the two training regimes was made. The researcher's initial perceptions of the teachers' initial low level of computer literacy were confirmed by a questionnaire, responded to by each participant. It would seem that the shorter raining period was more effective in raising the level of computer literacy and that if the training period was longer, the contact time should be increased to maintain support. Neither training period resulted in a significant increase in computer use, either as a personal tool or as a teaching aid. The failure to do so may be ascribed to a number of influences, one of which is the teaching style of individual teachers. Changing the teaching style of an experienced teacher takes time and more effort than was available for either training period.

A study of balance and gait following stroke : implications for rehabilitation

- Description: This study examined: the features and extent of the gait velocity decrement following stroke; the nature of the balance disorder and; investigated relationships between gait and balance. Twenty, fully-ambulant, hemiplegic subjects (12 men and 8 women), with a mean age of 57.2 years (± 10.7), were compared with 20 age- and sex-matched controls. Spatiotemporal gait kinematics were measured at five walking speeds ranging from "very slow" to "very fast". Balance was then measured while subjects maintained a variety of weight shift postures both with feet parallel and then in diagonal positions similar to those assumed during the double support phases of gait. Location and variability of centre of pressure (CP) were measured and the ranges over which CP could be shifted were calculated. Stroke subjects walked very slowly with their "fastest" walking speed (0.5 stat/s ± 0.23) no different from the "slowest" speed (0.38 stat/s ± 0.11) of the controls (p > 0.05). Differences between the other parameters were also found, many of which could be attributed to the differences in walking speeds. However, where the subjects walked at similar velocities, the hemiplegic sample walked with quicker and shoner strides suggesting a "cautious" gait pattern. The single support asymmetry of the strokes decreased with increasing walking speed. The positions of CP in the hemiplegic sample were found to be significantly displaced towards the unaffected leg and deficiencies were found in posterior shifts (p < 0.05). Postural sway was significantly greater in the hemiplegic sample implying less stable balance and the ranges over which the hemiplegic sample shifted weight were significantly less than the controls. The diagonal weight shift tests revealed the difficulty the stroke subjects experienced in shifting CP posterolaterally over the affected leg. Significant correlations were detected confmning the presence of relationships between static balance performance and gait. However, these correlation findings left considerable percentages of variance unexplained. These findings suggest that future rehabilitation should address the poverty of range of walking speed possessed by hemiplegic subjects as well as the reduced ability to weight shift over the hemiplegic limb, particularly posterolaterally. Further study to test these proposals is indicated.

- Description: In this study an attempt is made to describe and illuminate the current approaches to ESL writing in secondary schools in the Port Elizabeth-Despatch areas where Afrikaans is the first language of the pupils. Teacher and pupil Questionnaires were used as a means of data collection through which the approaches, practices and attitudes to the teaching of ESL writing in the secondary schools in the survey area could be reviewed and assessed. The teacher Questionnaire revealed that most respondents appeared to have a limited awareness or understanding of basic composing processes, especially the role of multiple drafting and teacher intervention in the form of interactive feedback. There is also evidence that there is a limited understanding of how these activities can be effectively implemented in a classroom situation. The pupil Questionnaire was used as a means to extend the understanding of teacher approaches to ESL writing as revealed in the teacher Questionnaire, to enable comparisons to be made and to evaluate the writing approaches currently practised in the ESL classroom. Many of the observations revealed in the teacher Questionnaire were echoed in the analysis of the pupil Questionnaire, especially the limited roles of planning and feedback, treatment of error, attitude to writing and the limited improvement in writing as pupils progress through the secondary school. The analysis also revealed that pupils were reluctant to expose, or share their work with audiences, were pre-occupied with error and viewed the teacher as grade-giver, grammarian and topic-provider. Topic selection was also revealed as a factor which influenced the pupils' negative or indifferent attitudes to writing. Although the process approach was considered a traditional approach to writing by 1986, the analysis and review of the Questionnaire data has revealed that a fair assessment of the state of ESL writing in the survey schools would place the current writing approaches in the traditional product- centred, form-dominated, teacher-centred mould. For this position to change, research pedagogy will need to become part of teacher training and the classroom so that there can be greater teacher awareness and understanding of composing processes and their implementation in the classroom. This is necessary, because research findings have revealed that a genuine orientation to a process approach and the application of composing stategies followed by good writers will result in improved writing progress and pupils having a more positive attitude to writing.

- Description: The main thesis of this dissertation is that even a casual analysis of African writing reveals that contemporary African literature has and is still undergoing a distinctive metamorphosis. This change, which amounts to a significant departure from the early fifties, derives its creative impulse from demonic anger and cynical iconoclasm and is triggered by the mind-shattering disillusion that followed independence. The proclivity towards tyranny and the exploitation of the ruled in modern Africa is traced by radical African creative writers to an ancient source: the legendary and god-like rulers of precolonial Africa. Ouologuem's Bound to Violence and Armah's Two Thousand Seasons and The Healers hypothesize that past sins begot present sins. The legendary warrior heroes of the past, whose glory and splendour were once exalted in African writing, are now ruthlessly disentombed and paraded as miscreants and despots, who not only brutalized and sold their people into slavery but also ideologically fabricated their own legends and myths in order to maximize their tyrannical power. The preoccupation of these works is, therefore, to divest the ancient heroes of their false glory. contemporary critics tend to perceive this anti-traditional posture purely as a modern trend in African literature. The truth of the matter, however, is that the literary foundations of this anti-nativist/anti-Afrocentric literary tradition were laid by Thomas Mofolo and Sol Plaatje, whose Chaka (1925) and Mhudi (1930) are the precursors. The five primary works in this study parody and veer away from the generally accepted traditional African epic heroism and recorded history towards a communal heroic ideal which celebrates the larger community instead of the single epic heroes normally romanticized in African legendary tradition. These novelists, while dismantling the European and African myths about Africa's Golden Age, also disfigure the often glorified ancient historical landmarks and the fabled heroes of Africa's oral and recorded history. The rationale behind this investigation is the fact that though these works have innovated, assimilated, and parodied the African oral arts, particularly traditional African epic heroism, no detailed study has been made to explore the literary transformation these texts have undergone as written works. Treating African texts only as appendages of Western literature may undermine the ability of the critical evaluations which go into the heart of these texts and unravel their deeper meanings. The outcome of this kind of approach is that pertinent issues of style and theme originating from negro-African metaphysics, oral traditions, and iconography could thereby be left unexplored. Besides, the bulk of the current body of criticism on African literature, particularly on colonial Africa, tends to concentrate on colonialist Christian values and Western literary production models. One of the overriding concerns of this research, therefore, is to veer away from merely rehashing Eurocentric pronouncements on European influences and literary modes parodied by these works, by taking a fresh. look at the texts from the perspective of Afrocentrism and in particular from the point of view of the traditional African oral bards. To this end, therefore, the dissertation is divided into six main chapters and a short concluding chapter: Chapter 1, A Survey of Black Representations of Pre-colonial Africa, functions as an introduction, sketches the European image versus the Black counter-discourse, and locates the study within the current debate on the concept of pre-colonial Africa's Golden Age. Chapter 2, Thomas Mofolo's "Inverted Epic Hero", the nucleus of the study I analyzes the anti-epic and ironic modes manipulated by the text and also maps out the epic generic framework which structures the whole dissertation. Chapter 3, Traditional African Epic Heroism Revised, discusses Plaatje's Mhudi, paying special attention to the text's deployment of the African epic genre as well as the caricaturist and the anti-heroic modes. In Chapter 4, Yambo Ouologuem's Bound to Violence is examined under the title A World Trapped in an Orgy of Violence, Barbarism and Servitude. African oral art is used as the hermeneutic key in unlocking the complexities of Ouologuem's novel. Chapter 5, The African Anti-Legendary Creative Mythology, scrutinizes Armah's Two Thousand Seasons, highlighting, among other topics, Armah's daring innovative stylistic experimentation. Chapter 6, entitled The Akan Iconic Forest of Symbols, deals with Armah' s The Healers, concentrating on the Akan iconographic backdrop which shapes and informs this work. And finally, The Metamorphosis of Traditional African Epic Heroism, the title of the concluding chapter, sums up this dissertation.

- Description: This study examined the often contrived advertising claims of the manufacturers of variable resistance isotonic machinery. Specifically, the study sought to ascertain whether certain equipment was compatible with musculo-skeletal and perceptual needs and limitations of the human user: that is, to determine whether presently installed eccentric cams, which provide the variable resistance, matched the users force curves. The format of this research was in the ergonomic tradition in which empirical research is not necessarily the primary avenue. Consequently the inter-disciplinary nature of ergonomics required small-scale laboratory- simulation experiments to be conducted in a diverse range of disciplines such as physiology, psychology and biomechanics. It was found that on all five pieces of variable resistance machinery analysed, a mismatch between the force curves and the eccentric cams exist. The cams were redesigned accordingly. The metabolic cost of performing fixed-rate isoinertial lifts was moderate. The psychophysical analysis revealed that perceptual responses indicated that the work was classified as 'light' and only at 30% stress levels do local cues begin to dominate. Based on these findings it was concluded that manufacturers advertising claims in the instances analysed were not well-founded and that variable resistance isotonic machinery should only be used to develop muscular strength and endurance, and do not effectively serve as weight-loss devices.

- Description: Hazards are an integral part of people-environment relationships. The impact of hazards locally and globally has become increasinglymore severe. particularly in the previous two decades. This is largely as a result of unwise human intervention in natural systems. The study of hazards at secondary school level affords valuable opportunities for learning about people-environment issues. This in turn, can promote a greater awareness of environmental problems. One of the most important current aims of Geographical Education is the development of critical thinking skills in pupils. Such skills are vital for equipping pupils with the necessary tools to understand and participate in solving the world's increasing human and environmental problems. The development of a critical faculty in pupils is best achieved by the use of learner-based participatory teaching strategies where pupils are involved in problem solving activities. Research has shown that British and South African Geography curricula reflect current thinking in Geographical education and learning theory. The 1992 Junior Secondary Geography Syllabus in line with these trends. includes a section for study on hazards. Hazards are presented primarily as case studies in modern Geographical texts. which is seen as one of the most effective ways of teaching hazards.

This study investigated the extent to which case study teaching materials on hazards are optimising opportunities available for effective learning within an Environmental Paradigm. An evaluation methodology, which is believed to have value for use by other researchers, was developed to suit the specific requirements of the study. The study findings reveal a poor realisation of the current aims of Geographical Education and learning theory, regarding the South African teaching materials.

- Description: Hazards are an integral part of people-environment relationships. The impact of hazards locally and globally has become increasinglymore severe. particularly in the previous two decades. This is largely as a result of unwise human intervention in natural systems. The study of hazards at secondary school level affords valuable opportunities for learning about people-environment issues. This in turn, can promote a greater awareness of environmental problems. One of the most important current aims of Geographical Education is the development of critical thinking skills in pupils. Such skills are vital for equipping pupils with the necessary tools to understand and participate in solving the world's increasing human and environmental problems. The development of a critical faculty in pupils is best achieved by the use of learner-based participatory teaching strategies where pupils are involved in problem solving activities. Research has shown that British and South African Geography curricula reflect current thinking in Geographical education and learning theory. The 1992 Junior Secondary Geography Syllabus in line with these trends. includes a section for study on hazards. Hazards are presented primarily as case studies in modern Geographical texts. which is seen as one of the most effective ways of teaching hazards. Research however suggests that South African textbooks have certain shortcomings. notwithstanding the importance placed on textbooks by teachers in this country. This study investigated the extent to which case study teaching materials on hazards are optimising opportunities available for effective learning within an Environmental Paradigm.

- Description: Sediments from periglacial and glacial environments were subjected to initial preparation and portions were subsequently further prepared using either the dichromate or the hydrogen peroxide method before being examined by scanning electron microscopy. Statistically significant differences did not occur in the results obtained for samples subjected only to initial or to initial and either of the two further preparations: it is concluded that initial preparation is satisfactory and further preparation unnecessary.

- Description: This study was aimed at evaluating the interdisciplinary nature of environmental education within the colleges of education in Bophuthatswana. Data collection was based on semi-structured interviews with college lecturers and, to a lesser extent, on observations during a workshop with environmental educators from Bophuthatswana. Knowledge was gained about college related factors which influence the varying extent to which environmental education is being implemented within the colleges of education. Lecturers' understanding of the interdisciplinary nature of environmental education and related concepts was explored. Insights were also gained into problems of implementation which included lecturers' limited understanding of the concept of interdisciplinarity, structural ambiguities, limited training and experience, and a lack of clarity in both local and international literature on environmental education concepts and terms. Specifically the study sought to illuminate the dichotomy between theory and practice, the conflict between the dominant curriculum paradigm and the new emerging paradigm, and tensions between the interdisciplinary nature of environmental education and subject-based disciplines, which lead to problems of implementation. The study could make an important contribution to the current curriculum debate on environmental education in South Africa by illuminating the dichotomy between the theory and the practice of environmental education, and the problems involved in translating interdisciplinary approaches into workable classroom practices within discipline based curriculum structures.

- Description: Growing awareness of the environmental risks associated with modernity has contributed to an increasing demand for information about the environment. Conservation and other environmental organisations receive many such requests for information. The research reported here was motivated first, by the view that these requests presented an opportunity for environmental education, and second, by a concern that this potential was not being realised. The research question was thus "How can environmental education be supported by optimally responding to requests for environmental information?" It is argued that social change is the raison d' etre of environmental education as a response to environmental risks. Further, it is proposed that this might be best achieved through an approach described here as socially critical environmental education. The study comprised an historical review of the Enviro Facts Project, a recent attempt to meet the need for environmental information; a questionnaire survey; interviews; and workshops. Results were collected from 115 questionnaire responses; 23 telephone interviews and nine face-to-face interviews; and six workshops. The research design was participative. It aimed to answer the research question through co-developing practical solutions with participants. Further, it endeavoured to be of practical relevance to those participants. Conclusions are drawn as to how the research question might be answered. Recommendations are made as follows. Responses to environmental information requests might best support socially critical environmental education through an approach characterised by: * a recognition of the importance of responding optimally to environmental information requests, as well as a recognition of existing structures and resource materials with which to respond; * the mobilisation of those structures and resource materials through, for example, the effective marketing and distribution of resource materials; informed and focused networking to make existing resources and capacities more accessible; and the effective use of libraries to provide environmental information; * the enhancement of the capacities of local sources of environmental information. The findings of this study could usefully inform both resource development in environmental education, and those who in their line of work respond to requests for environmental information.
