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

复杂系统、知识管理与组织学习过程动态模型研究   总被引:13,自引:0,他引:13  
知识经济时代的组织是一个具有无尺度网络结构的复杂系统。知识管理是知识经济时代的必然要求。组织学习作为组织获取核心竞争力和可持续发展能力的重要手段,是一个动态的过程。本文在系统回顾相关研究成果的基础上,从复杂系统的视角对知识经济时代复杂环境下的组织学习动态复杂过程进行了系统的模型整合和创新,并对构建学习型组织可能遇到的障碍进行了一系列对策分析。  相似文献

The acquisition of reading skills is known to rely on early phonological abilities, but only a few studies have investigated the independent contribution of the different steps involved in phonological processing. This 1‐year longitudinal study, spanning the initial year of reading instruction, aimed at specifying the development of phonological discrimination, awareness and various aspects of phonological memory and at assessing their respective contributions to early reading acquisition. Our results show an increase in performance at each phonological processing step, but also suggest a qualitative evolution in their relative importance. Hierarchical regression analyses indicate that reading skills are mainly predicted by phonological awareness measured at the kindergarten stage and, subsequently, by phonological memory abilities measured at the end of first grade. More precisely short‐term memory for serial‐order information seems to contribute to the development of decoding abilities, while phonological knowledge stored in long‐term memory seems to influence word recognition.  相似文献

The aim of this study was to examine the effectiveness of either a standard care programme (n = 9) or a 12-week supported exercise programme (n = 10) on glycaemic control, β-cell responsiveness, insulin resistance, and lipid profiles in newly diagnosed Type 2 diabetes patients. The standard care programme consisted of advice to exercise at moderate to high intensity for 30 min five times a week; the supported exercise programme consisted of three 60-min supported plus two unsupported exercise sessions per week. Between-group analyses demonstrated a difference for changes in low-density lipoprotein cholesterol only (standard care programme 0.01 mmol · L(-1), supported exercise programme -0.6 mmol · L(-1); P = 0.04). Following the standard care programme, within-group analyses demonstrated a significant reduction in waist circumference, whereas following the supported exercise programme there were reductions in glycosylated haemoglobin (6.4 vs. 6.0%; P = 0.007), waist circumference (101.4 vs. 97.2 cm; P = 0.021), body mass (91.7 vs. 87.9 kg; P = 0.007), body mass index (30.0 vs. 28.7 kg · m(-2); P = 0.006), total cholesterol (5.3 vs. 4.6 mmol · L(-1); P = 0.046), low-density lipoprotein cholesterol (3.2 vs. 2.6 mmol · L(-1); P = 0.028), fasting β-cell responsiveness (11.5 × 10(-9) vs. 7.0 × 10(-9) pmol · kg(-1) · min(-1); P = 0.009), and insulin resistance (3.0 vs. 2.1; P = 0.049). The supported exercise programme improved glycaemic control through enhanced β-cell function associated with decreased insulin resistance and improved lipid profile. This research highlights the need for research into unsupported and supported exercise programmes to establish more comprehensive lifestyle advice for Type 2 diabetes patients.  相似文献
