There is a growing concern about the struggles of early career teachers and an understandable questioning of the preparation being offered by teacher education courses. Are our preservice teachers being given workable strategies and techniques to allow them to survive the early years? Is it strategies and techniques that are primarily at issue here? Could it be that there is something more fundamental, to do with an underlying philosophical understanding about human nature, the desire to learn and the need to relate? I want to suggest that instruction about strategies and techniques is too often built on an insecure and incompatible foundation of assumptions about the nature of the world of sentient beings and their relationships. Ontology matters. Philosopher Spinoza divided the world of thought into ideas that were adequate – contributing to our well-being, potency and happiness – and those that were inadequate – leading us to feel weak, at the mercy of outside forces, and sad. I want to argue, with Spinoza, that inadequate ontologies lead to a sense of impotence and frustration, and that adequate ideas – a stronger ontology – can underpin and sustain a more durable pedagogy. I explore this idea by looking at some classroom events through a Spinozean lens. 相似文献

The net neutrality debate is one of several sites of struggles to adapt and redefine rights and obligations of stakeholders in the Internet-centric communications system. Its outcomes will shape the future of the Internet and influence the level and distribution of its benefits. We identify key values that drive the net neutrality discussion and examine the governance mechanisms proposed to achieve these objectives. We find that there is no single policy instrument that allows realization of the range of valued political and economic objectives simultaneously. Contrary to some of the claims advanced in the current debate, safeguarding multiple goals requires a combination of instruments that will likely involve government and nongovernment measures. Furthermore, promoting goals such as the freedom of speech, political participation, investment, and innovation calls for complementary policies. 相似文献

One common contemporary usage of the term “diagnostic uncertainty” is to refer to cases for which a diagnosis is not, or cannot, be applied to the presenting case. This is a paradoxical usage, as the absence of diagnosis is often as close to a certainty as can be a human judgement. What makes this sociologically interesting is that it represents an “epistemic defence,” or a means of accounting for a failure of medicine’s explanatory system. This system is based on diagnosis, or the classification of individual complaints into recognizable diagnostic categories. Diagnosis is pivotal to medicine’s epistemic setting, for it purports to explain illness via diagnosis, and yet is not always able to do so. This essay reviews this paradoxical use, and juxtaposes it to historical explanations for non-diagnosable illnesses. It demonstrates how representing non-diagnosis as uncertainty protects the epistemic setting by positioning the failure to locate a diagnosis in the individual, rather than in the medical paradigm. 相似文献

In this response, I advocate for the value of considering theory in the design‐based research that Gersten describes in “Behind the Scenes of an Intervention Research Study.” I argue that such an emphasis: is consistent with the literature on design experiments, is integral to advancing knowledge building within domains, serves to advance the work of a field, and supports the dissemination of instructional research. I illustrate these points, drawing upon the research described in the article by Gersten. 相似文献

Does adviser mentoring add value? A longitudinal study of mentoring and doctoral student outcomes 总被引:1,自引:0,他引:1
This study of the impact of doctoral adviser mentoring on student outcomes was undertaken in response to earlier research
that found (a) students with greater incoming potential received more adviser mentoring, and (b) adviser mentoring did not
significantly contribute to important student outcomes, including research productivity [Green, S. G., and Bauer, T. N. (1995).
Personnel Psychology 48(3): 537–561]. In this longitudinal study spanning 5 1/2 years, the effect of mentorship on the research productivity,
career commitment, and self-efficacy of Ph.D. students in the ‘hard’ sciences was assessed, while controlling for indicators
of ability and attitudes at program entry. Positive benefits of mentoring were found for subsequent productivity and self-efficacy.
Mentoring was not significantly associated with commitment to a research career. 相似文献

Since 1998, upper level secondary education pupils in the Netherlands are required to choose one of four study profiles with their own specific and fixed combinations of final examination subjects. With the aid of multilevel analyses, the extent to which this situation has led to changes in the determinants of mathematics and science choice (i.e. selection of a science profile) is examined for more than 3500 pupils. From a meritocratic perspective, the relative contributions of background characteristics versus personal aptitude are examined. The introduction of the study profiles appears to have produced sharper lines with respect to sex and socio‐economic status. Optimal use is thus not made of existing science talent. 相似文献

The so-called leaking STEM pipeline (dropout in STEM education) has been the subject of many studies. The large interest of scholars in plausible causes of this leakage has resulted in a number of meta-reviews describing factors at system, school and student level related to interest and persistence in STEM education. The STEM pipeline discussion has also resulted in a large number of programmes aimed at enhancing STEM interest and persistence in STEM education. Although these programmes have been widely evaluated, there seems to be no consensus about which interventions are successful in raising interest in STEM or persistence in STEM education. This study reports the results of a systematic review of empirical studies in which the effectiveness of STEM-related interventions are assessed. Initially, 538 studies were found. The quality analyses showed that only a few of these evaluation studies are designed in such a way that it is likely that the found effects are caused by the intervention. Although some potentially effective interventions were found, this review shows that there is still a need for research into the effectiveness of those programmes, especially with regard to programmes preventing talented and initially motivated STEM students to drop out of STEM education. 相似文献

A new on-line titration method and device based on a new technique-continuous flow titration is described.By the means of electronically controlled switching of a solenoid valve,the main component of the system,the equivalent point of the titration is easily determined.Several kinds of mixing tools were examined.whereby a self-made mixing chamer with minimum volume gave best results and was therefore used in the dveice,The error of the titration is within 0.2% and the relative standard deviation(RSD) is below 1.2%,The results show no difference compared with a commercial device,meanwhile the new on-line titration system is cheaper and fully automated and thus easy to hand and less slovent consumption. 相似文献
