Die onderwystegnologiese toerusting van Transvaalse onderwysstudente met besondere verwysing na oudiovisuele media
No full textProefskrif--PU vir CHO1. AIM: The aim of this study is to ascertain to what extent student
teachers of Transvaal universities and colleges of education are
technologically prepared for their teaching profession. Relevant aspects of teacher training with special reference to the Transvaal were attended to. The importance of this undertaking is partly due to the fact that the modern school is compelled to
make greater use of technological aids to prepare the child optimally for the complex world of the future. Some general implications based on the findings of this study are pointed out. 2. METHOD: A study was made of available literature on educational technology. Attention was also given to the historical development of educational aids, present practices of teacher training overseas and in the Republic of South Africa and the compilation of criteria for the training of European student teachers in Transvaal.
Additional information about the present practice in Transvaal was gained by visits to the four universities and the four teacher training colleges, interviews with lecturers responsible for audiovisual training and questionnaires to student teachers in their final year. 3. FINDINGS: 3.1 Problems experienced by the modern school and
attempts to overcome these: The task of the modern school is complicated by the great expansion of knowledge, the rapid increase in the pupil population, problems of financing and a shortage of teachers. Curriculum reform, differentiation, psychological approach in education and new approaches such as the systems approach,
programmed teaching and improved methodology are a few attempts to overcome the abovementioned problems. The value of method and techniques is best illustrated by a discussion of the Nontessori-method, the Winnetkaplan, the Daltonplan, the Morrison-method, team-teaching, schools of the air and teaching by means of television. In addition attention is given to improved teacher training and guidance, as well as the
recruitment of sufficient teachers. In recent years technology and technological innovation, in the form of improved communication media, improved ways of manufacturing, visits to space, etc., has had an increasing influence on society. The new communication media are considered as possible means of solving some of the problems experienced by the modern school. Auditive and visual media can possibly be used to quicken learning and promote understanding. In the modern school we use child-centered education with full consideration of pupil ability and developmental stage.
3.2 The development of education technology and the present state of affairs: A brief summary of the historical development of technology of education as a relatively recent field of study is given. Early founders of educational technology are the Sophists,
Abelard and Comenius, followed by Pestalozzi, Froebel and Herbart. After 1900 Thorndike, Dewey, Montessori, Burke and Lewin played an important part in the founding of the modern educational technology. The empirical approach of children, analysis of learning matter, individualized instruction, progress according to ability,
scientific planning of education, better teacher training, thorough educational research, differentiated educational techniques and method, improved communication and the implementation of new educational aids are some of the characteristics of present instructional technology. To elucidate the present state of affairs in the RSA, a brief
summary of recent developments in the USA, Britain, Netherlands, Western Germany, USSR, France and Rhodesia was given. Modern instructional technology, based on scientific teaching theory and method, developed after the Second World War. It is characterized by the use of auditive and visual media according to modern instructional techniques such as programmed instruction, mastery learning, and others aimed at giving each child the opportunity of progressing according to ability. To achieve this
aim, continued attention is given to innovation of the curricula, improved teacher training, in-service training of teachers and the application of modern technology in all the abovementioned countries. Major problems experienced by educationalists are the lack of knowledge among teachers and others about innovatory measures, a lack of materials, the fact that pupils do not respond to new techniques and the lack of knowledge concerning new techniques among teachers as well as an unwillingness to experiment with or to implement the new. Conservatism can possibly be eliminated by defining educational aims clearly, by introducing new techniques in a well-defined way,
by adapting teacher training in accordance with new media and techniques, and by encouraging teachers to make use of these in their teaching practice. 3.3 Principles and requirements for the choice and use of audiovisual aids: The increased use of audiovisual media to overcome some of the problems experienced by the modern school, is sometimes called the technological teaching revolution. In view of the above it is essential for teachers to take note of the psychological principles of learning and especially the way in which man gains experience by means of perception, how learning matter is retained and how it is recalled. The preschool phase, primary school phase, secondary school phase and tertiary phase were discussed to point out how the child should make use of direct experience - initially to acquire and accumulate knowledge which will make abstract thought possible. In his cognitive approach to media usage Salomon refers to the interaction between media, message, educational task and learner as factors which facilitate the effectiveness of instruction. According to didactic principles. teaching aids can be classified an ascending sequence from direct experience to the spoken or written word as the most abstract. According to communication principles, events in the classroom can be described as psychological interaction between a teacher and a group of pupils. To facilitate efficient communication it is essential that communication media with which the child is
familiar, are used in school. 3.4 Audiovisual aids must comply with the following criteria:
The choice of media is affected by criteria such as project variables which include educational aims. availability of time, the number of learners, the cost-effectiveness ratio, reliability and durability; psychological variables such as the senses, sensory limits and the Hernandez-Peon effect; and learner variables such as ability and interest, media experience and preference. In addition the following criteria must also be
considered: integrateability, curricular enforceability, manageability, versatality, the ability to stimulate imagination, the ability to motivate pupils, the ability to encourage individualization and selfactivity, it must improve communication, create balance, must encourage efficiency, must be economic and must facilitate experience. 3.5 Audiovisual media in the didactic educational situation: Attention was given to a classification of media. This was followed by a discussion of media characteristics, requirements for
media usage and advantages and limitations of media usage. Lastly an integrated media approach was briefly described. 3.6 Training of teachers for the use of audiovisual media and educational technology: It is a too formidable task to give a detailed description of the present state of affairs in all countries as far as this subject
is concerned. Some of the most relevant, such as the USA, UK, Netherlands, USSR, France and Rhodesia were discussed. Certain universities and teacher training colleges in the USA provide excellent training facilities and programs for the use of audiovisual media and educational technology. In Western European countries such as the United Kingdom, Netherlands, France and Western Germany, audiovisual aids and educational technology form integral parts of the education systems. The training of student teachers, in-service training of teachers, introduction of new media and materials, and the production of software are well attended to. Modern techniques and methods, educational aids and educational technology are emphasized in the training of student teachers and the in-service training of teachers in the USSR. Audiovisual media are used according to technological principles in Rhodesian teacher training. By means of in-service training, teachers in Rhodesian schools are encouraged to make the best
possible use of modern educational technology. In the RSA the provinces were discussed separately. It is encouraging to find that educational technology has been accepted throughout the country. In the training courses at the various universities and teacher training colleges in all provinces, thorough attention is given to audiovisual aids in the educational technological program. By in-service training teachers become
acquainted with and are encouraged to make use of audiovisual media and technological principles in the schools. Attention is also given to production of software.
3.7 Criteria for the training of teachers in the use of-audiovisual aids: In view of differences in the training courses in audiovisual media and educational technology at the different universities and teacher training colleges in Transvaal, the following criteria
for the training of teachers, were compiled: (i) An intensive knowledge of educational technology is required; (ii) a would-be-teacher should have a thorough knowledge of
audiovisual media; (iii) he should know possible uses and shortcomings of the various media; (iv) he should know which media can be used in combination; (v) the training course should not be too theoretical; (vi) the lecturer should set an example in the use of media; (vii) too much technical knowledge should not be included in the course;
(viii) audiovisual education should be an integral part of subject methodology; (ix) greater co-operation between media centres and subject methodology should be encouraged; (x) training in the production of audiovisual materials (software) is essential. 4. SUMMARY OF THE PRESENT STATE OF AFFAIRS IN TRANSVAAL: A thorough empirical investigation with regard to educational technology in Transvaal followed. In conclusion the teacher training is tested according to the abovementioned criteria. 4.1 Integration of modern technological principles: It became evident that not all students were properly trained in principles underlying the use of audiovisual media, as some lecturers stated that students were not properly trained in technology. As far as theoretical principles are concerned there are vast differences between die different institutions. Certain universities and colleges emphasize technological training while very little attention is given to training in the practical use of the various media.
Micro-teaching and television are used by some institutions only. 4.2 A thorough knowledge of audiovisual media is essential: It seems that some students did not have the opportunity of handling certain apparatus. This is due to the fact that some of the universities and colleges do not have the amenities or sufficient apparatus to facilitate practical experience. Some students however rer.eived help from teachers at the schools where they were placed for practice teaching. 4.3 Student teachers should be acquainted with possibilities and limitations of audiovisual aids: Lecturers do not set the example of possible uses of audiovisual aids in their lectures. Students feel that ractical use can only be achieved if uses of these aids can be demonstrated in a practical situation. 4.4 The use of media in combination should be emphasized: In some cases sillabuses do not facilitate the proper instruction of the use of media in combination such as a slide-sound combination or the language laboratory. 4.5 The course should not be too theoretical: Enough time should be allocated for the practical handling of apparatus and materials. Because of large classes it is not always possible (classes of 49 to 180 students). 4.6 Lecturers should set an example to the student: This is not always the case. because some lecturers are not fully acquainted with the use of media themselves. Motivation and preparation in the use of audiovisual aids and materials
are essential. 4.7 Some sillabuses include unnecessary technical knowledge
about apparatus or a detailed discussion on electricity, its origin, direct current, alternating current, etc., which is quite unnecessary. If a less detailed description of apparatus or unnecessary subject matter is excluded, more time can be alotted to practical work. 4.8 Audiovisual training should form an integral part of subject methodology: In audiovisual training the student should be taught how to handle
apparatus while the application could be taught in the specializing subject or subject methodology. 4.9 Greater co-operation between media centres and subject
methodology is required: This can facilitate advancement of technological principles.
4.10 Training in the production of a4diovisual materials: Although this is encouraged by the majority of universities and colleges, some students stated that they did not have the
opportunity of producing audiovisual materials. Opportunity for the production of transparencies, photostats, slides, taperecordings and transcription are essential.
4.11 A uniform syllabus for educational technology for all teacher training in Transvaal is essential. A syllabus committee consisting of representatives of the four universities and the four teacher training colleges should be formed.Doctora

Inspirations, Imitations and Borrowings from Primitive Art by the 20th Century South African Artists
No full textThe aim of the article is the presentation of the influence of African art at the beginning of the 20th century in South African. Primitivism and the awareness of Primitive Art have played a crucial role in the history and development of 20th century European and American Art, in a number of different ways, although the dynamics of how this happened are complex and varied. The purpose of this article is limited only to the presentation of the influence of indigenous Art from the African Continent and the socalled primitive or aboriginal art in the South African art tradition of European descent in the first half of the 20th century such as: Jacobus Hendrik Pierneef, Irma Stern, Walter Battiss and Alexis Preller. All of them have started to utilize the African iconography in their own paintings and decided to borrow some typical stylistic elements and narratives from indigenous works of African Art.Udostępnienie publikacji Wydawnictwa Uniwersytetu Łódzkiego finansowane w ramach projektu „Doskonałość naukowa kluczem do doskonałości kształcenia”.

The ecclesiology of stanley hauerwas: resident aliens and die concrete church
No full textThis thesis focuses on Stanley Hauerwas' thought about the church insofar as it represents a concrete ecclesiological approach. I argue first that concrete ecclesiology, while often appearing in the work of its proponents as methodological presuppositions rather than an explicit doctrine of church, is sufficiently distinctive that Hauerwas' ecclesiology can be placed within it. Through exploring Hauerwas' theology in Chapter 1， I suggest that his ecclesiology shares key influences with concrete approaches through Barth, Frei, Wittgenstein and Yale postliberalism. Hauerwas also shares concrete ecclesiology's concerns in terms of its interest in the concrete church as a valuable subject for theological reflection, attention to distinctive Christian practices, theologically therapeutic and pastoral-minded approaches to reflecting on the life of the church, and concern for how the church interacts with the world. In Chapter 2, I evaluate Hauerwas' work by seeing how his ecclesiology deals with the realities of sin, division and confusion within the church. I argue that Hauerwas' rhetoric idealises the practices of the church, so there are limitations to the concreteness of his ecclesiology. Combined with Hauerwas' problematic and overstated use of narrative, this idealisation results in insufficient focus on the provisional and fallible nature of the church's practices, and a deleteriously pugilistic attitude towards the world. In Chapter 3， I explore how Barth balances his ecclesiology by holding its theologically centrifugal elements in tension with the various creedal contexts in which it is set forth. This not only mitigates Hauerwas' criticisms of Earth's ecclesiology, but also proffers ways in which a robust doctrinal setting would maintain the prophetic force of Hauerwas' challenges to the church without allowing Christian practice to bear the weight of realising God's kingdom. I then argue that Christ's resurrection is a helpful doctrinal setting for a methodologically and pastorally wise concrete ecclesiology
Author response: Mechanistic insights into the active site and allosteric communication pathways in human nonmuscle myosin-2C
No full textBothaville en sy mense
No full textHierdie boek bet sy verskyning te danke aan 'n begeerte by histories-bewuste
mense van Bothaville om die bonderjarige bestaan van die dorp feesvierend in
1991 te herdenk. Daardeur het Bothaville aangesluit by die talle ander dorpe
en gemeenskappe/organisasies/instansies wat veral in die jongste twee tot drie
dekades dié verboogde en groeiende historiese bewussyn openbaar.
Aanvanklik is beplan dat publikasie nog in die feesjaar sou geskied, maar dit
was spoedig duidelik: dat dié doelwit nie binne so 'n kort tydsbestek haalbaar
was nie. Finansiele bronne was boonop ook nie voldoende om die
onvoorspelbare eskalerende navorsing te finansier nie en 'n groot deel van die
werk moes noodgedwonge by die reeds druk akademiese programme van die
twee skrywers ingepas word. Hierdie toedrag van sake bet beduidend
vertragend op die projek ingewerk.
Hierdie boek is nie 'n wetenskaplike werk in die normale sin van die woord
nie. Met inagneming van die genoemde beperkinge ten opsigte van tyd en
finansies, is die navorsing wat die boek ten grondslag lê, asook die
bevindinge en gevolgtrekkinge waartoe geraak is, egter ten volle
wetenskaplik-gefundeerd
Unquantifiably low aldosterone concentrations are prevalent in hospitalised COVID-19 patients but may not be revealed by chemiluminescent immunoassay.
No full textOBJECTIVE: Previous studies have reported conflicting findings regarding aldosterone levels in patients hospitalised with COVID-19. We therefore used the gold-standard technique of liquid chromatography-tandem mass spectrometry (LCMSMS) to address this uncertainty. DESIGN: All patients admitted to Cambridge University Hospitals with COVID-19 between 10 March 2020 and 13 May 2021, and in whom a stored blood sample was available for analysis, were eligible for inclusion. METHODS: Aldosterone was measured by LCMSMS and by immunoassay; cortisol and renin were determined by immunoassay. RESULTS: Using LCMSMS, aldosterone was below the limit of detection ( 744 nmol/L (P = 0.005). CONCLUSION: When measured by LCMSMS, aldosterone was found to be profoundly low in a significant proportion of patients with COVID-19 at the time of hospital admission. This has likely not been detected previously due to high levels of interference with immunoassays in patients with COVID-19, and this merits further prospective investigation
Humor in kinderverhale : 'n vergelyking tussen geselekteerde Afrikaanse en Nederlandse tekste
No full textThesis (M.A.)--Potchefstroom University for Christian Higher Education, 2001Humour is regarded as important in a variety of disciplines and when literature is studied, it
becomes clear that humour is very important in the development of the individual. There are
various ways in which the individual may be exposed to humour, and one of these is
children's stories.
It became clear, however, that up to now very little research has been done on the subject of
humour in children's stories. An instrument for the studying of humour in children 's stories is
necessary:_ an instrument that takes into account developmental psychology, literary theory
and humour. When all these are combined, the nature, scope and effect of humour in
children's stories can be determined.
Six texts, 'n Haas moet doen wat 'n haas moet doen (Martie Preller) , Aliens en engele (Leon
de Villiers), Vincent van Gogga (Philip de Vos), Minoes (Annie MG Schmidt), Het verhaal van
Bobbe/ die in een bakfiets woonde en rijk wi/de warden (Joke van Leeuwen) and Nooit de
buren bijten (Paul van Loon), were examined individually. In each text the humorous
situations were highlighted and discussed. These discussions led to the conclusions that
were drawn.
Humour manifests itself in a variety of subjects in the text; it is not limited to light-hearted
subjects. All the narrative elements and textual aspects have a role to play in the humour of
a story. Humour makes the story accessible to different readers, and the text becomes a
reading and learning experience. Humour can be an instrument in the hand of the author
and the mediator. They sensitise the young reader for humour in stories and through that the
reader's reading and life skills are widened.Master
