田径跳跃项目专项动作协调能力研究

通过对田径跳跃项目专项动作特征的研究,对田径跳跃项目专项动作协调能力进行了探索,认为田径跳跃项目的动作协调能力在运动技术上表现为：爆发性用力;跑跳结合;摆、蹬结合和空间动作的控制与定向能力四个方面,这将有助于我们对其专项运动协调能力水平做出科学的量度和判断,提高专项运动协调能力.     

Classroom action research on formative assessment in a context-based chemistry course

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).

社会学制度主义的政治行动逻辑观——"适合性逻辑"探析

制度与个人行为之间的关系是新制度主义的核心问题,在西方历史上二者之关系曾出现过整体主义、神秘主义、自由主义和行为主义特征。新制度主义通过算计途径和文化途径解决二者关系,前者发展成为结果性逻辑和理性选择新制度主义,主张个人理性和集合制度;后者发展成为适合性逻辑和社会学制度主义,主张集体理性和整合制度。社会学制度主义者认为适合性逻辑是政治行动的基本逻辑,制度既适应环境和集体行为,也改造着环境和个人行为,是消极制度和积极制度的统一。社会秩序是制度分析中的突出主题。从适合性逻辑出发,培养有知识的公民和促进合作及发展社会资本是维持秩序的重要途径。     

Rationalising public support for private early childhood education and care: the case of Finland

ABSTRACT

In Finland, early childhood education and care (ECEC) is traditionally publicly provided. However, private ECEC provision has increased during the past decade, largely as a result of financial support from the public sector. Drawing on qualitative interviews with municipal decision-makers, this article identifies three frames within which publicly subsidised private ECEC provision and marketisation are rationalised: the pragmatic frame, the government frame and the choice frame. The results show that even though market logics and tendencies seem to have gained a strong foothold in local policies, there is a keen interest in universalism and maintaining public control over local ECEC provision.

Increasing the uptake of peer feedback in primary school writing: findings from an action research enquiry

This article reports on how an action research strategy was used to increase children's uptake of feedback during peer assessment in primary school writing. Several different strategies were used in the study that had been successful in increasing students’ uptake of peer feedback in contexts such as higher education. In order to evaluate how successful these actions were, several different data collection methods were drawn upon to triangulate findings including children's work, observations, informal interviews and mind mapping. Thematic analysis was used to analyse the data generated. Findings are consistent with those from research in other settings which suggest that pupils make better use of feedback if: it is task-involving and useful; there is sufficient time given for them to act on it and discuss it with their peers; and they are asked to reflect on how it has been used to improve the quality of the assessed work.     

The P,A and R of participatory action research with unaccompanied girls

This article discusses the possibilities and the challenges of conducting participatory action research (PAR) with unaccompanied asylum-seeking children and youth. Drawing from a PAR project with 12 unaccompanied asylum-seeking girls in a Finnish reception centre, the paper explores the P, A and R of PAR asking the following questions: what kind of participation is relevant in such a challenging phase of life, being in a new society without families; what is ‘good’ action in these circumstances; and, finally, what is the involvement of the children in conducting the research when they find the practical end product clearly more interesting? The results show that as a flexible and child-centred research method, PAR can be used to promote the participation of children and youth in a reception centre. However, participation in research should not be mandatory: unaccompanied children who have often had too many responsibilities and inadequate protection in the past desire to be assured that it is the adults’ responsibility to make the right decisions concerning the improvements of the children’s lives.
