Using critical discourse analysis as a methodology for analysis, this paper sets out the nature and form of the challenges directed to the compulsory schooling sector by the knowledge economy that is contained in key policy and related documents put out by the OECD, the World Bank and the UK government. The OECD and the World Bank’s policy agendas are increasingly important in setting policy and programme agendas for the developed and developing countries respectively; however there are important differences between the two institutions regarding how education should be redesigned. The World Bank’s redesign of education favours the market and individualism as the means for developing knowledge and skills for the knowledge economy. The OECD, however, while concerned with human capital formation, rejects the market model in favour of an institutionally embedded liberalism to overcome the problems posed by tacit knowledge. The UK, on the other hand, has promoted the idea of personalized learning. The paper suggests that this idea is particularly problematic for developing a system of innovation for the economy that is dependent on high levels of social interaction.
The first half of the twenty‐first century will, I believe, be far more difficult, more unsettling, and yet more open than anything we have known in the twentieth century. I say this on three premises; none of which I have time to argue here. The first is that historical systems, like all systems, have finite lives. They have beginnings, a long development and finally, as they move far from equilibrium and reach points of bifurcation, a demise. The second premise is that two things are true at these points of bifurcation; small inputs have large outputs (as opposed to times of the normal development of the system, when large inputs have small outputs); and the outcome of such bifurcation is inherently indeterminate. The third premise is that the modern world system as a historical system has entered into a terminal crisis and is unlikely to exist in 50 years. However, since its outcome is so uncertain, we do not know whether the resulting system (or systems) will be better or worse than the one in which we are living, but we do know that the period of transition will be a terrible time of troubles, since the stakes of the transition are so high, the outcome so uncertain, and the ability of small impacts to affect the outcome so great.

A study was carried out to assess the effectiveness of a representational visual imagery training programme on the reading and listening comprehension of a group of poor listening comprehenders in Year 2 (mean age: 7 years 8 months). Results indicated that relative to a matched control group, the experimental group improved significantly on a curriculum-based test of listening comprehension, a standardised test of reading comprehension and a measure of story event structure, with results approaching significance on an adapted test of listening comprehension. The implications of the results for early institution of visual imagery training in the context of listening comprehension instruction are discussed.  相似文献

Oscillation and Complexity in Early Infant Behavior   总被引:1,自引:0,他引:1  
Cyclic fluctuation is a ubiquitous property of spontaneous motor activity in the human fetus and neonate. Oscillation occurs on the scale of minutes, and irregularity is one of its most characteristic properties. To determine whether cyclic motor activity (CM) persists beyound the neonatal period (1 month after birth), and beyound what has been called the period of the fetus ex utero (2–3 months after birth), 30 infants were studied at monthly intervals from 1 to 4 months after birth during active sleep and awake. Spectral analysis was used to quantify the rate, strength, and irregularity of CM. To examine the characteristic irregularity of awake CM more closely, a nonlinear forecasting technique, developed to study chaotic dynamics in other fields, was used to estimate the predictability of spontaneous movement in a state space reconstructed from the time series. The rate and irregularity of CM during active sleep and awake, and its strength during active sleep, did not change across the first 4 postnatal months. However, there was a pronounced drop in the strength of awake CM from 2 months onward, and a concurrent increase in the broad-band power of fluctuations faster than 2 cycles/min. The predictability of awake CM also dropped abruptly between 1 and 2 months, especially for prediction intervals less than 20 sec. The changes at 2 months reflect the introduction of a source of variation with a shorter time constant than fetal-neonatal CM, and which is specific to awake periods. The source of these effects may be moment-to-moment interactions between CM and attention.  相似文献

Polymerase chain reaction (PCR) and gel electrophoresis have become common techniques used in undergraduate molecular and cell biology labs. Although students enjoy learning these techniques, they often cannot fully comprehend and analyze the outcomes of their experiments because of a disconnect between concepts taught in lecture and experiments done in lab. Here we report the development and implementation of novel exercises that integrate the biological concepts of DNA structure and replication with the techniques of PCR and gel electrophoresis. Learning goals were defined based on concepts taught throughout the cell biology lab course and learning objectives specific to the PCR and gel electrophoresis lab. Exercises developed to promote critical thinking and target the underlying concepts of PCR, primer design, gel analysis, and troubleshooting were incorporated into an existing lab unit based on the detection of genetically modified organisms. Evaluative assessments for each exercise were aligned with the learning goals and used to measure student learning achievements. Our analysis found that the exercises were effective in enhancing student understanding of these concepts as shown by student performance across all learning goals. The new materials were particularly helpful in acquiring relevant knowledge, fostering critical-thinking skills, and uncovering prevalent misconceptions.  相似文献

Conclusion In conclusion, the operation of systematic data gathering procedure in the RMIT Counselling Service has provided a body of data from a number of years, enabling analysis of sex differentials in utilization of the Service. Some differentials have been indicated and further lines of research suggested to ensure that the advertising strategies and counselling models employed by the Service are better matched to the gender characteristics of its client population.  相似文献

In recent years, a number of developmental counselling programs have become increasingly popular among counselors and teachers both in Canada and the United States. Programs such as Developing Understanding of Self and Others (D.U.S.O.), the Human Development Program (H.D.P.) and Toward Affective Development (T.A.D.) are designed to promote greater self-awareness, greater self-confidence and better interpersonal skills among students. In the present paper, the two most widely used elementary school programs, D.U.S.O. and the H.D.P., are examined and compared in terms of their objectives and format. Next, the research on each program is reviewed and finally suggestions for further research are made.Paper presented at the 9th International Round Table for the Advancement of Counselling, Thessaloniki (Greece), April 1980.

This qualitative study used Interpretative Phenomenological Analysis to consult with 16 autistic UK higher education (HE) students about their experiences of success. An in-depth participatory approach encouraged participants to become co-analysts of their data.

Participants offered counter-narratives to deficit-based interpretations of autism, giving accounts of making themselves ‘extra-visible’ as autistic in order to assert their rights. The autism diagnosis was perceived both as an aid to self-understanding and a cause of additional barriers. In raising awareness of their own needs, participants contributed to broader understandings of autism within their academic communities, inadvertently becoming educators and role models. The research highlights the extra effort required by autistic students to thrive within higher education and the barriers imposed by current requirements to both pursue formal diagnosis, and to disclose it in order to receive adjustments. The research was novel in its approach and in its focus on success, revealing original findings in relation to the challenges and barriers faced by high-achieving autistic students, and the implications for a more inclusive higher education curriculum and environment are considered.  相似文献

When we design information technology we risk building specific metaphors and models of human activities into the technology itself and into the embodied activities, work practices, organisational cultures and social identities of those who use it. This paper is motivated by the recognition that the assumptions about human activity used to guide the design of particular technology are made active, in use, by the interaction design of that technology. A fragment of shared design work is used to ground an exploration of different solutions to one of the technical problems that arise when technology is used to support similar work over distance. The argument is made that some solutions to design problems are better than others because they enable human interaction in different ways. Some solutions enhance the possibilities for human agency, others diminish it. This means that there can be a moral basis for choosing between alternative interaction design decisions that might otherwise be considered equivalent in terms of the functionality and usability of the technology.  相似文献

This paper describes and evaluates aspects of a professional development programme for existing CS teachers in secondary schools (PLAN C) which was designed to support teachers at a time of substantial curricular change. The paper’s particular focus is on the formation of a teacher professional development network across several hundred teachers and a wide geographical area. Evidence from a series of observations and teacher surveys over a two-year period is analysed with respect to the project’s programme theory in order to illustrate not only whether it worked as intended, by why. Results indicate that the PLAN C design has been successful in increasing teachers’ professional confidence and appears to have catalysed powerful change in attitudes to learning. Presentation of challenging pedagogical content knowledge and conceptual frameworks, high-quality teacher-led professional dialogue, along with the space for reflection and classroom trials, triggered examination of the teachers’ own current practices.  相似文献
