The paper reportsdocuments our experiences using chat as a medium for exams in a so-called flexible education. The type of education is adult learning and planning of education. The experiences show some interesting results. It is a very different way of communicating, which leaves a new level of initiative and control to the student. A new way of assessment has qualified the study process, and this work has examined one way to do virtual assessment. 相似文献

In German sports science, the national elite sport promotion system is a steady topic of discussions. The federal government and the German Olympic Sports Confederation (DOSB) expect new impetus of the reformed elite sport system in the areas of, inter alia, young athlete promotion, scientific support, and the coaches’ situation in German elite sport. The present article is a discipline-specific approach to these three issues for men’s artistic gymnastics. The first author served in various functions in German gymnastics (former squad athlete, young athletes‘ coach, academic teaching) for several years and is familiar with essential problems due to close communication with gymnasts, coaches, scientists, and officials. The purpose of this article is to point out specific challenges in men’s artistic gymnastics in view of the present debate on the German elite sport promotion system. This is intended to stimulate further discussions on solution approaches concerning the common exploitation of potentials. 相似文献

Fast unloaded movements (i.e. striking, throwing and kicking) are typically performed in a proximo‐distal sequence, where initially high proximal segments accelerate while distal segments lag behind, after which proximal segments decelerate while distal segments accelerate. The aims of this study were to examine whether proximal segment deceleration is performed actively by antagonist muscles or is a passive consequence of distal segment movement, and whether distal segment acceleration is enhanced by proximal segment deceleration. Seventeen skilled taekwon‐do practitioners were filmed using a high‐speed camera while performing a high front kick. During kicking, EMG recordings were obtained from five major lower extremity muscles. Based on the kinematic data, inverse dynamics computations were performed yielding muscle moments and motion‐dependent moments. The results indicated that thigh deceleration was caused by motion‐dependent moments arising from lower leg motion and not by active deceleration. This was supported by the EMG recordings. Lower leg acceleration was caused partly by a knee extensor muscle moment and partly by a motion‐dependent moment arising from thigh angular velocity. Thus, lower leg acceleration was not enhanced by thigh deceleration. On the contrary, thigh deceleration, although not desirable, is unavoidable because of lower leg acceleration. 相似文献

Fourth year students in psychology and social work from two South African universities worked together across boundaries of race and class in a course which required them to engage in a personal reflexive way with issues of community and identity. A combination of face-to-face workshops and online tutorial groups was used. The course was demanding of both staff and students, but preliminary analysis suggests that the creation of virtual communities may be of benefit in assisting students in their preparation for the challenges of working in a diverse and unequal society. 相似文献

Online learning is increasingly being used in Higher Education, with a number of advantages to online learning being identified. One of these advantages is the suggestion that online learning provides for equality of opportunity. This article reports on students’ evaluations of the use of e-learning in a collaborative project between two South African universities. The results highlighted both positive and negative evaluations of the use of e-learning. The positive aspects identified were that e-learning provided for ease of communication between parties, and easy access to information and learning material. Negative aspects identified were that it presented some technical challenges; online communication was disjointed; there was unequal access to computers between students from the two universities; students felt that more face-to-face interaction is needed. The issue of unequal access to computers and the internet is highlighted as a crucial issue for e-learning in the South African context, and for the fostering of a democratising educational discourse. 相似文献

ABSTRACTThe need to keep things cool for durability should be the single most powerful influence on storage design. The simplest temperature control is to moderate the outside temperature by a combination of thermal insulation and heat capacity. The low energy storage building is a lightweight, thermally insulated, airtight building put on top of an uninsulated floor slab laid directly on the ground. The thermal insulation is calculated to even out the daily temperature cycle but to allow an annual temperature cycle which is about half the amplitude, but much smoother, than the annual temperature cycle outside. The winter temperature inside will nearly always be above ambient and so will maintain a moderate RH without need for either humidification or dehumidification. The temperature inside in summer will be below ambient and thus will force dehumidification of the infiltrating air. However, the airtightness of the building allows intermittent dehumidification with low energy consumption, less than one kWh/m3 per year. There now exist enough buildings designed on this principle to reassure curators that highly valued collections can be stored in a space with a gentle temperature cycle and with an RH stability as good as air-conditioning usually achieves. 相似文献

The term “community” holds historical connotations of political, economic, and social disadvantage in South Africa. Many South African students tend to interpret the term “community” in ways that suggest that community and community psychology describe the experiences of exclusively poor, black people. Critical pedagogies that position the teaching process as a transformative activity and that challenge student perceptions about the status quo are central in teaching community psychology. This article uses the subdiscipline of community psychology to discuss the importance of pedagogy. It uses a module that was presented at Stellenbosch University (SU) in the Western Cape, South Africa, as an illustrative example. The module was taught collaboratively with the social work department at the University of the Western Cape. Forty-five psychology students from a historically white university (SU) and 50 social work students from a historically black university (UWC) engaged in face-to-face workshops and virtual (e-learning) assignments that interrogated notions of the self, community, and identity. Final student essays were analysed qualitatively for themes illustrating aspects of the human capabilities approach to pedagogy adopted in this project. 相似文献

The paper describes a collaborative curriculum development project implemented over 3 years at 2 universities in the Western Cape Province of South Africa. The project involved a short module in which students in their fourth year of study interacted and learnt collaboratively across the boundaries of institution, discipline, race and social class, about the concepts of community, self and identity. The pedagogic approach adopted is described, as well as the responses of the students, and a brief reflection on some of the learning outcomes attained. The paper considers the learning processes which the curriculum development team experienced, and suggests that in order to facilitate learning for an ‘uncertain world’, the curriculum designers, too, need to engage in learning processes in which they make themselves vulnerable, mirroring some of the learning processes they expect the students to undergo. 相似文献
