Factors associated with students’ attitude change in online peer assessment – a mixed methods study in a graduate-level course

Abstract

Positive student attitude towards peer assessment can be demonstrated through high-quality peer assessment activities. Research findings on students’ attitudes before and after such activities were mixed. This study was conducted using a mixed-methods approach to investigate the underlying factors influencing students’ attitude change. Participants were students enrolled in an online graduate-level assessment course in the college of education in a university in the southeast United States in the fall of 2017 (N?=?31). Surveys and interviews were used to collect quantitative and qualitative data separately, both of which indicated that perceived accurate and specific feedback tended to help students shift to more positive attitudes towards online peer assessment. In addition, final task score improvement after the activity was correlated with positive attitude change. Qualitative results also identified other factors, such as communication with the peers’ work and logistic concerns. The current study offers insights for researchers and instructors to promote positive attitude changes in online peer assessment activities.     

倾斜角度对基于相变材料的散热器在脉冲式热负荷作用下瞬时性能的影响

研究目的：通过实验方法定量研究在相变材料较为剧烈的熔化传热过程中散热器倾斜角度的改变对其瞬时性能所产生的影响。创新要点：定量研究在倾斜角度从水平到垂直时,储能式散热器在脉冲式热负荷作用下瞬时性能的变化规律,并在所研究的工况范围内给出了最优的倾斜角度参考值。研究方法：采用电加热方法模拟电子器件所产生的热源,通过调节电压改变脉冲式热负荷的强度和作用时间,并根据热电偶测量所得的加热表面温度变化来表征储能式散热器的瞬时性能。重要结论：在一定的倾斜角度下工作,可以有效提升基于相变材料的储能式散热器的瞬时性能。在加热功率为40 W、以75℃为目标时,其有效保护时间的相对增长可达约67%。     

海南黎族与汉文化的关系述论

海南黎族有悠久的历史、自己的语言和独特的文化特征。中原汉族自秦代踏足海南岛之后，历两汉至明清，徙琼者日众。汉族的迁入和汉文化向黎区的播散，对黎族产生深刻的影响。它加速了黎族社会前进的步伐，促进黎族文化的变迁，以及黎族与汉族的融合．黎族的文化面貌及其分布格局因此发生深刻的变化。     

Lost in translation? Emotional intelligence,affective economies,leadership and organizational change

Not until the late 1990s did the rational/emotional binary embedded in mainstream literature on educational leadership and management come under challenge. Now the emotional dimensions of organisational change and leadership are widely recognised in the leadership, organisational change and school improvement literature. However, the dissolution of the binary did not draw from feminist social theory, critical organisational theory, the sociology of emotions or critical pedagogy. Instead, the strongest influence in educational leadership and administration has been from psychological theory, management theory and brain science, mobilised particularly through Goleman's notion of emotional intelligence. This article undertakes a feminist deconstruction of two texts: one from organisational theory by Goleman and the other on educational leadership and school improvement, in order to explore how ‘emotion’ has been translated into educational leadership. As a counterpoint, I identify the gaps and silences, appropriations and marginalisation identified from feminist perspectives. I argue that the emotional labour of teaching and leading cannot be individualised because emotion is both relational and contextual.     

A quiet revolution – International influence,domestic elites and the transformation of higher technical education in Ireland 1959–72

The upgrading of higher technical education which began in the 1960s marked the most influential intervention by the Irish government in the third-level sector since the establishment of the independent Irish state. A series of reforming initiatives extended educational opportunity and transformed the status of technical education at higher level. International pressures undoubtedly proved influential in stimulating policy change. The Organisation for Economic Co-operation and Development (OECD) encouraged far-reaching reforms through its critical evaluation of educational facilities for technical training in Ireland. But educational reform was not imposed by international agencies on a reluctant corps of national politicians and officials. International influences dovetailed with changing attitudes toward technical education within the Irish political and official elite. Leading politicians and public officials showed an increasing awareness that the previous neglect of technical education was untenable in an era of economic development and educational expansion. It was a timely combination of international scrutiny and domestic political re-appraisal, which triggered a radical restructuring and expansion of higher technical education in Ireland.     

Contrastive Analysis of Intonation and Tone in Chinese and English

In English,intonation is the main research object of supra-segmental phonology,it refers to the changes of tone and pitch.English intonation is non-tone language which means the word meaning will not changed with the changing of the independent word's tone,while Chinese is Tone language,in which tone often determinates the meaning of word,different tones are representative of different meanings.Chinese language function exerts differently in tone and intonation,and it is a bit complicated compared with English.     

刍议都铎时代的圈地运动

都铎王朝统治时期 ,英国社会处于从封建制度向资本主义制度过渡的历史阶段 ,即资本原始积累时期。作为原始积累的方式之一 ,圈地运动在都铎时代第一次达到高潮 ,它是 14 - 15世纪英国社会大变动的产物。都铎时代的圈地狂潮具有直接暴力的典型特征 ,它包括掠夺公共土地、侵占农民份地、没收教会土地等等。圈地运动使耕地减少、牧场增加 ,这只是一种表面现象 ,由圈地引起的新旧生产关系的消长 ,反映了英国农业社会中资本主义成长的实质。就都铎时代圈地运动对封建生产关系的扫荡作用而言 ,它的历史意义决不在 17世纪中叶的政治革命之下。

Is It a Challenge or a Threat? A Dual-Process Model of Teachers' Cognition and Appraisal Processes During Conceptual Change

What accounts for well-meaning teachers' lack of implementation of subject-matter reforms, such as making one's classroom centered on problem solving, even when they positively value the reform and believe they are implementing it in their classrooms? Teachers' subject-matter beliefs may constrain them from adopting practices that conflict with those beliefs. The purpose of this article is to propose a theoretical model, the Cognitive–Affective Model of Conceptual Change, that integrates key findings from overly cognitive models of belief change with motivational and affective factors found in social psychology theory and research. This model explains why teachers' beliefs about instruction are resistant to reforms that challenge their existing beliefs, and it provides a conceptual framework within which to devise a better means of advancing teachers' beliefs and supporting them in the process of implementation.
