国际比较视野下的课例研究：背景、现状与启示

在反思“远离教学的变革运动”基础上,课例研究成为许多国家和地区推进教学变革的方法论。比较世界主要国家和地区的课例研究可以发现：就维持课例研究存续的动力机制而言,主要由体制性要求、项目推动和自愿开展三种。在操作模式上,虽然不同国家和地区的具体步骤不同,但都体现出群体性合作、过程性反思和持续性改进的共同特征。同时源于不同的研究传统,不同国家和地区的研究方法和研究范式各有侧重。在支持系统方面,不同国家存在结构性差异。吸收课例研究的国际经验,未来我国课例研究的发展可以朝如下方面努力：拓展课例研究的研究视角;改进课例研究的操作方法;迈向教学法科学的创造;把课例研究整合进职前教师教育体系。

Intangible assets and firm heterogeneity: Evidence from Italy

The positive impact of intangible assets on several measures of economic performance is well documented in the literature. Less clear is what initially leads firms to invest in intangible assets. The latter is particularly important because, at least for the Italian manufacturing sector, firms exhibit strong heterogeneity in their investments in intangible assets. In line with the capability-based theory of the firm, we argue that the firm's propensity to invest in intangible assets can be explained by factors that are internal and specific to the firm. Making use of a rich dataset, we test and provide support for our hypotheses. In particular, we find that the propensity to invest in intangible assets increases with the firm's size, human capital, and historical intangible asset base. This points towards the existence of a cumulative process of intangible asset accumulation, which may account for most of the heterogeneity observed in the data. The paper adds to the previous literature in two ways: first, it highlights the existence of strong intra-industry heterogeneity in intangible asset investments, and second, it offers an explanation for such heterogeneity.

反应停对小鼠荷瘤H_(22)的影响

目的研究不同剂量反应停及反应停协同环磷酰胺对小鼠荷瘤H22(肝癌)实体型肿瘤的影响。方法建立小鼠肝癌移植实体型肿瘤模型,比较不同剂量反应停对小鼠肝癌的影响,同时观察反应停协同环磷酰胺对小鼠肝癌的影响。通过研究反应停对小鼠迟发型变态反应的影响探究其免疫作用。结果反应停对小鼠荷瘤H22呈现明显剂量依赖性抑制作用,反应停与环磷酰胺具有协同抗小鼠肝癌作用。反应停对小鼠迟发型变态反应呈剂量依赖性促进作用。结论反应停具有抗肝癌作用,而且与环磷酰胺具有协同抗肿瘤作用,此作用与反应停抗免疫作用有关。     

Do local contributions affect the efficiency of public primary schools?

Are public schools that rely on local resources for a greater share of their financing more cost-effective? Could financial decentralization lead to more efficient schools? This paper attempts to answer these questions using cost, financial sources and student achievement data from Philippine primary schools, which are financed primarily from central sources but which also raise funds from other sources, to differing degrees. It concludes that schools which rely more heavily on local sources, such as contributions from the local school board, municipal government, parent-teacher associations (PTA) and other sources are more efficient—i.e. have lower cost, holding constant for enrollment and quality. A 1% increase in the share of financing coming from local sources will lead to a decline in total costs of 0.135%, or about the cost of providing for a place for one more student.     

高校健美专项课专项考核内容与评价方法的调查分析

采用文献资料法、调查研究法,对高校健美专项课专项考核内容与评价方法进行研究分析,提出健美专项课主要以平卧推举和负重深蹲作为专项技能考核内容,以学生克服自身体重作为评价学生健美专项练习的基本标准,以双臂屈伸、引体向上、仰卧起坐作为专项素质考核内容。尊重学生的个体差异,以学生挑战自我为目标,已逐步成为健美专项课专项考核评价方法的基本趋势。建议制订细化的易于教师和学生实际操作的评价表。     

The role of pupil voice as a trigger for teacher learning in Lesson Study professional groups

This paper focuses on the role of pupil voice as a trigger for teacher learning and for improving teaching quality. This is investigated in the context of Lesson Study (LS), a professional development model that can incorporate pupil voice into teachers’ collaborative reflections on lessons. Data are from two LS groups of mathematics teachers in London (one primary and one secondary school). Video-recorded pupil interviews and teacher discussions were transcribed. Episodes of teacher discussions were coded for reference to pupil input and subsequent impact on future plans. Qualitative analysis of discussions examined whether some pupils’ input was favoured over others’. Results are significant in pointing to LS as a mechanism for attending to pupil voice. In so doing, it is suggested that pupil input provided a challenge for teachers in their interpretations of pupil learning, evaluating lessons and planning, and in contributing to teacher learning from LS.     

英汉语篇省略对比研究——以《第二十二条军规》为例
