The dimensions of maltreatment: introduction

This special issue includes an introduction and seven papers exploring dimensions of maltreatment including type, severity, chronicity, and substantiation status of referrals to CPS, utilizing a subsample of the LONGSCAN studies. Each paper examines one of the dimensions of maltreatment from various perspectives to determine if different conceptualizations of a dimension, examined in isolation, account for different amounts of variation in child outcomes. A final paper assesses the relationship of the combined maltreatment dimensions, including interactions, on a single sample of maltreated children from the LONGSCAN study. This final paper explores the individual contribution of the "best" conceptualizations of the maltreatment dimensions in relation to each other, and to the 10 child outcomes of interest. Implications of the findings from these papers for future research on dimensions of child maltreatment are discussed in two independent commentaries.     

The affective dimensions of learning science

In this study, we identified middle school and college students' prior ideas about electrostatic induction and interviewed them through presenting observational evidence which supported or refuted their own prior ideas. Their responses to the evidence were interpreted from perspectives based on philosophies of science, especially the Popperian and Lakatosian views of scientific hypothesis testing. In the process of confirmation, almost all of the students showed a logical error known as an 'error of affirmation of the consequent' in a syllogism. The students' falsification processes were classified into two groups: those which rejected the hard core of prior ideas, and those which modified the students' protective belt of auxiliary ideas related to the hard core while still preserving the hard core. From an analysis of the students' falsification processes, it was found that the Lakatosian rather than the Popperian view was more acceptable in understanding the students' responses to the conflicting evidence. It was observed that the quality of the understanding of auxiliary ideas should also play an important role in the changing of core concepts.     

论大学通识教育的文化向度

教育是实现由自然人向社会人转化的系统社会化过程,文化内容构成了教育的核心内容。教育的本质与个体人由社会价值体系所衡量的素质提高密切相关,所以任何教育都应该是素质教育。通识教育是实现大学素质教育的有效途径,而文化向度构成了大学通识教育最重要的向度。通识教育文化向度上的国际化视野与本土坐标,确立了通识教育在传统文化与西方文明内容选择上的基本原则。     

The dimensions of research in undergraduate learning

Most Australian Universities offer a selection of research-intensive pathways at the graduate level, which provides opportunities for independent inquiry and intellectual autonomy. Undergraduate students, however, are somewhat short-changed in their experience in research. They are exposed to a variety of areas and disciplines, which forms a general cluster of knowledge, but students graduate without obtaining the skills associated with research and inquiry. Digital communication networks and the ways in which information is disseminated in modern society play an important role in the way people live and learn. At the same time, younger generations are emerging with greater skills in digital literacy, which bears an impact on how knowledge is produced and information is shared. This prompts to question, are undergraduate students acquiring the generic attributes that will help them to cope with the complexities of an information-driven society? The following article is based on the premise that undergraduate students need to be empowered to construct their own knowledge as potential producers rather than mere consumers of knowledge. It provides a synthesis of cross-disciplinary perspectives and educational debates that support the argument for, and benefits of, providing research-enriched learning for undergraduate students. This article adopts a framework for the dimensions of research in undergraduate learning. The different models presented in this article aim to illustrate the various ways that research can be integrated with teaching to benefit learning.

The dimensions of academic scholarship: Faculty and administrator views

Faculty and administrators responded to 32 activity statements related to scholarship on a frequency basis and on the characteristicness of the role. Approximately 1,000 faculty members in 24 colleges and universities and 55 administrators from 5 of the schools participated. Factor analysis revealed 6 dimensions of scholarship — professional activity, research (publishing), teaching, service, artistic endeavor, and engagement with the novel, the last being a new conception, one valued highly by both faculty and administrators in all types of colleges and universities. Significant differences appeared with respect to faculty and administrative views on the importance of research in regional universities.     

The five dimensions of social pedagogy within schools

A ‘social pedagogy’ approach is increasingly being adopted by professional agencies in the United Kingdom involved in dealing with the welfare, care and education of children. This paper argues that, in the context of schools, social pedagogy can be characterised as taking an integrated view of the needs of the whole child in terms of five key dimensions: care and welfare; inclusion; socialisation; academic support; and social education. Whether or not these changes in professional practice lead to the widespread employment of a professional called a ‘social pedagogue’ remains to be seen. However, integrated working practices have already had an impact on how teachers are expected to deal with the needs of pupils identified as giving a cause for concern.

教育政策的四重视角

认识教育政策的本质涵义对教育政策分析具有决定性意义。本文认为，应从现象形态、本体形态、过程特点和特殊性质四个视角来全面认识和理解教育政策的涵义。在现象形态上，教育政策是教育领域政治措施组成的政策文本及其总和；在本体形态上，教育政策是关于教育利益的分配；在过程方面，教育政策是一个动态边疆的主动选择的过程；在特殊性质方面，教育政策在活动过程和利益分配方面具有不同于一般公共政策的特殊性。
