This paper analyses one aspect of a pan-African action research project called ITMUA (Implementing the Third Mission of Universities in Africa). This particular paper draws on the data from that project to explore the National University of Lesotho’s contribution to lifelong learning in its communities. It provides background information on the ITMUA initiative and analyses interview and focus group responses to two case studies in terms of their contribution to lifelong learning. It uses, as its analytical framework, a modified version of Mbigi’s African perspective on the four De Lors’ ‘pillars’, by adding a fifth pillar, courtesy of Torres. The paper argues that community engagement is a two-way process between universities and their wider constituencies with opportunities for mutual lifelong learning. But there are also challenges of understanding and process which must be addressed if the full range of these lifelong learning pillars is to be accommodated within African contexts. The paper provides an introduction to the history of community engagement in Africa as a university mission, followed by a brief discussion of lifelong learning within African perspectives. After describing the particular context of Lesotho, the concept of community service and community engagement in contemporary African contexts introduces the action research project and the case studies. The final part of the paper presents and discusses the research findings.  相似文献

Two experiments with goldfish were performed to investigate the role of stimulus-reinforcer vs. response-reinforcer relationships in omission training and the role of stimulus localizability in a positive behavioral contrast paradigm. The directed behavior of fish, like that of pigeons and rats in other studies, was greatly influenced by positive stimulus-reinforcer correlations, as evidenced by maintained contacts of a signal for food, even though such responses terminated the signal and cancelled reinforcement delivery. Goldfish exhibited positive behavioral contrast when the signals for reinforcement and nonreinforcement were displayed directly on the response key, but no contrast was observed when variations in a diffuse houselight stimulus were used as signals for reinforcement or nonreinforcement. Analysis of sequential-trial data yielded effects analogous to Pavlovian positive and negative induction. Theoretical and methodological problems were briefly considered.  相似文献

This study describes the process of defining a hypothetical learning progression (LP) for astronomy around the big idea of Solar System formation. At the most sophisticated level, students can explain how the formation process led to the current Solar System by considering how the planets formed from the collapse of a rotating cloud of gas and dust. Development of this LP was conducted in 2 phases. First, we interviewed middle school, high school, and college students (N?=?44), asking them to describe properties of the current Solar System and to explain how the Solar System was formed. Second, we interviewed 6th-grade students (N?=?24) before and after a 15-week astronomy curriculum designed around the big idea. Our analysis provides evidence for potential levels of sophistication within the hypothetical LP, while also revealing common alternative conceptions or areas of limited understanding that could form barriers to progress if not addressed by instruction. For example, many students' understanding of Solar System phenomena was limited by either alternative ideas about gravity or limited application of momentum in their explanations. Few students approached a scientific-level explanation, but their responses revealed possible stepping stones that could be built upon with appropriate instruction.  相似文献

The ability to build arguments is a crucial skill and a central educational goal in all school subjects including science as it enables students to formulate reasoned opinions and thus to cope with the increasing complexity of knowledge. In the present cross-sectional study, we examined the domain-specificity of argumentative writing in science by comparing it with a rather general type of argumentation as promoted in first-language education and with formal reasoning to gain insight into different forms of argumentation on theoretical and empirical levels. Using a paper-and-pencil test, we analyzed written argumentations and the reasoning abilities of 3,274 Grade-10 students in German secondary schools. Correlation and multiple regression analyses as well as a qualitative analysis of students' answers to a subset of tasks in the domains of science and first-language education were conducted. Results showed moderate relations between argumentation in science, argumentation in first-language education, and reasoning. Half of the variance in argumentation in science was explained by individual differences in argumentation in first-language education and reasoning. Furthermore, the examination of written arguments revealed differences, for example, in students' weighing of pros and cons. We assume that the familiarity of the underlying scientific information may play an essential role in the argumentation process and posit that it needs to be investigated in more detail. Overall, the study indicates that investigating the argumentational abilities of learners in first-language education and reasoning abilities can help to shed light on the domain-specificity of argumentation in science.  相似文献

The main purposes of this article are to identify the dimensions of organisational knowledge creation strategies (EICE model: exploration, institutional entrepreneurship, combination, exploitation) and to clarify the relationship between the organisational knowledge creation strategies and its knowledge asset. For these purposes, guided by knowledge-based view and knowledge creation theory, we propose an EICE model and explore its effect on the knowledge asset. We further suggest the managerial implications and theoretical implications. The main managerial implication is that the knowledge creation strategies model may help manager to make effective strategies for knowledge creation within the organisation. The main contributions to organisation theory are extending Nonaka's knowledge creation theory to form a new strategic model for knowledge creation.  相似文献

When Alfred A. Knopf published the U.S. edition of Simone de Beauvoir'sLe Deuxième Sexe asThe Second Sex in 1953, their marketing deemphasized the book's existentialism and feminism. Rather they promoted it with comparisons to the Kinsey report and stressed its scientific merit. The translator's preface, his condensations, and prepublication promotion avoided overt sensationalism and invested it with scientific and intellectual cachet. This promotional strategy, though a somewhat inaccurate portrayal of the work, set the tone for its critical and popular reception and contributed to both its initial sales and its longevity.  相似文献

The article is based on a year's ethnographic work at a West Midlands comprehensive school, which is described. The usual genderising pattern of subject choice and behaviour are identified, and used as the basis of an analysis of the differences, real and imagined, between boys and girls and their expectations of secondary schooling.

Having identified quietness as one of the distinguishing characteristics of girls at Cator Park school, I relate this to their own assessment of how they accommodate to the demands of school. This highly selective adaptation is suggested as one reason why the boys are puzzled by the behaviour of girls in school, and it is suggested that it allows the girls to retain their private identity outside school. The conclusion is that quietness is a successful adaptation to the situation of girls in school, and should not be viewed as a weakness.  相似文献

In 2014, three librarians at the University of San Diego came together to explore open educational resources (OER). Coming from both technical services and digital collections, we were well-versed in the economic challenges facing today’s libraries. In order to formulate the approach that would work best for our campus, we first had to educate ourselves on the past, present, and possible future of the Open Access movement. While traditionally Open Access has focused on serials, OER offer the opportunity to expand its benefits to other formats. This article examines opportunities and tensions surrounding OER, as well as highlighting major players on the OER landscape. Our efforts began with a focus group for faculty to assess their own knowledge of and opinions on OER. After establishing a stipend budget, we sent out a call for proposals to faculty who were interested in participating in the Copley OER Initiative.  相似文献

The initial stance position (ISP) has been observed as a factor affecting the execution technique during taekwondo kicks. In the present study, authors aimed to analyse a roundhouse kick to the chest by measuring movement coordination and the variability of coordination and comparing this across the different ISP (0°, 45° and 90°). Eight experienced taekwondo athletes performed consecutive kicking trials in random order from every of the three relative positions. The execution was divided into three phases (stance, first swing and second swing phase). A motion capture system was used to measure athletes’ angular displacement of pelvis and thigh. A modified vector coding technique was used to quantify the coordination of the segments which contributed to the overall movement. The variability of this coordination (CV) for each ISP was also calculated. Comparative analysis showed that during the stance phase in the transverse plane, athletes coordinated movement of the trunk and thigh with a higher frequency of in-phase and lower frequency of exclusive thigh rotation in the 0° stance than the 90° stance position (< 0.05). CV was also influenced by the different ISP. During the first swing and the majority of the second swing phase, predominant in-phase coordination of the pelvis and thigh was observed. Including exercises that require in-phase movement could not only help athletes to acquire coordination stability but also efficiency. The existence of a constraint such as ISP implies an increase of the variability when the athletes have to kick from ISP they are not used to adopt (i.e., 0° and 90° ISP) as an evidence of adaptability in the athletes’ execution technique.  相似文献
