Combining the best of two worlds: a conceptual proposal for evidence-informed school improvement     

Chris Brown  Kim Schildkamp  Mireille D. Hubers 《Educational research; a review for teachers and all concerned with progress in education》2017,59(2):154-172

Abstract

Background: Data-based decision-making (DBDM) and research-informed teaching practice (RITP) are key to teacher and school improvement. Currently, however, DBDM and RITP represent two distinct approaches to developing evidence-informed practice (EIP) and do not correspond to the all-encompassing notion of EIP envisaged by many academics and commentators.

Purpose: DBDM and RITP are usually employed independently of each other. Each is associated with its own theoretical perspectives and research base, and each has its own pitfalls and strengths. Yet the approaches employed appear to be complementary, suggesting that there might be value in combining DBDM and RITP into one overarching process for achieving EIP. This paper presents the conceptual analysis and arguments for this proposal.

Sources of evidence: Drawing from literature and previous research in the fields of DBDM, RITP and EIP, we describe both DBDM and RITP, before comparing and contrasting the integral aspects of each.

Main argument: Our analysis leads us to suggest that not only is there overlap between these two approaches, but the strengths of each appear to mirror and compensate for the weaknesses of the other. As such, we argue that it is important that decisions in education are based on a combination of personal judgement, research evidence and local school data. This is because such a combination is likely to lead to equitable, effective and efficient decisions that are informed by values and preferences, grounded in context and steeped in practices that have been shown to be effective elsewhere.

Conclusions: We suggest that an effective strategy for EIP might be to achieve ‘the best of two worlds’ by integrating DBDM and RITP. In line with evidence-informed practices in medicine and management, this means EIP in education can finally be engaged in as a holistic approach to educational decision-making that critically appraises different forms of evidence before key improvement decisions are made. Our proposed approach, Evidence informed School and Teacher Improvement, is thus designed with the aim of enhancing the quality of educational provision by employing these evidence types as part of a systematic cycle of inquiry, focused on continuously improving the quality of learning in schools.  相似文献   

LD端面抽运Nd:YVO4温度场及热形变分析     

李锋  高荣发  张继良  刘宝盈  白晋涛 《商洛学院学报》2006,20(4):5-8

目的研究方形截面Nd：YVO4激光晶体在端面抽运情况下的温度分布及端面热形变；方法数值分析；结果得到激光晶体棒内温度场及热形变的数值解，给出了不同吸收系数下晶体中的最大温升和端面热至形变；结论吸收系数α越大，热源越向抽运端面集中，从而在端面形成一个相对集中的高温区，温度梯度分布表明晶体内具有侧向和轴向热流．端面热至形变相对于球面透镜存在高阶球差．选用较小的吸收系数有利于减小端面上的热应力和热至形变，而消除这一热效应的有效方法是采用复合晶体．  相似文献

周恩来行政决策的价值取向     

张志祥 《河西学院学报》2003,19(3):1-4

决策主体对决策客体作出准确无误的价值判断，是决策过程中的一个核心问题，实际上也是一个价值取向问题。行政决策价值取向在现实的行政活动中，不仅影响着行政效能的发挥、行政机制的完善，而且立接影响总行政活动的成败。周恩来的行政决策以为人民服务、求真务实、廉洁自律、精干高效为价值取向。对搞好我们今天的政府建设具有非常重要的现实意义。  相似文献

Predicting Two Components of Career Maturity in School Based Adolescents     

Peter A. Creed  Wendy Patton 《Journal of Career Development》2003,29(4):277-290

Three hundred and sixty-seven secondary school students across five year levels (8–12) were assessed for levels of career maturity (attitude and knowledge), work commitment, work value, career decidedness (indecision and certainty), career decision-making self-efficacy and self-esteem, and indicated their age, gender, socioeconomic status, school achievement and work experience. Using two multiple regression analyses, the predictor variables were able to account for 52% of the variance of career maturity attitude, and account for 41% of the variance of career maturity knowledge. Self-efficacy, age, career decidedness (certainty) and work commitment were the main predictors of career maturity attitude. Age, gender, career decidedness (certainty), work commitment and career decidedness (indecision) were the main predictors of career maturity knowledge. Results demonstrated the importance of examining two aspects of career maturity (attitude and knowledge), and were discussed in the context of Super's (1957, 1990) theory of career development.  相似文献
