Automatically structuring domain knowledge from text: An overview of current research

This paper presents an overview of automatic methods for building domain knowledge structures (domain models) from text collections. Applications of domain models have a long history within knowledge engineering and artificial intelligence. In the last couple of decades they have surfaced noticeably as a useful tool within natural language processing, information retrieval and semantic web technology. Inspired by the ubiquitous propagation of domain model structures that are emerging in several research disciplines, we give an overview of the current research landscape and some techniques and approaches. We will also discuss trade-offs between different approaches and point to some recent trends.     

Improving Preservice Middle Grades Science Teachers’ Understanding of the Nature of Science Using Three Instructional Approaches

The purpose of this study was to investigate changes in preservice teachers’ understanding of the nature of science (NOS) as a result of four activity-based interventions that represent three instructional approaches used in a middle grades science methods course. Ten participants’ understanding of NOS and their perceptions about the activity-based interventions were investigated. Data were collected using open-ended questionnaires and in-depth interviews before and after the interventions. Written artifacts and recorded group discussions were collected during the interventions. The results of this study showed that inclusion of various approaches to teaching NOS can contribute to developing preservice teachers’ understanding of NOS. The activities complemented each other in the teaching of the NOS components. In addition, the preservice teachers perceived that the four interventions were helpful in improving their understanding of NOS and in preparing them for future teaching.     

Different mysteries,different lore: An examination of inherited referencing behaviors in academic mentoring

Library and information science (LIS) dissertations cite a wide variety of literature, reflecting the interdisciplinary nature of the field. A review of 76 LIS dissertations was undertaken to determine whether the disciplinary background of the dissertation adviser influences the citing behaviors of the dissertation author. Of the 76 dissertations, 38 were advised by individuals with a disciplinary background in LIS and 38 were advised by individuals with a disciplinary background outside of LIS. The Library of Congress subclass for each citation was determined according the venue of publication. The most cited authors overall and by each group were determined, as well as the percentage of citations to LIS literature over time. LIS-advised dissertations were found to have cited a wide variety of literature. The percentage of citations in LIS-advised dissertations to LIS literature has declined from a peak of 59% to 21%. Citations to the most-cited authors in each group were largely exclusive to the LIS-advised dissertations, and nonLIS-advised dissertations generally do not appear to cite the same bodies of academic literature.     

Dartmouth's College Course I

Abstract

This article describes the background, activities, and outcomes of the Advanced Technology Environmental Education Center and its Summer Fellows Institute as a model for disciplinary and cross-disciplinary infusion of environmental science and technology content, curriculum, and methods into the classroom. The authors describe experiences, themes, and activities that occurred during 5 years at the Summer Institute for some of the nation's top high school and community college teachers.     

Analysing attempts to support outdoor learning in Scottish schools

The new ‘Curriculum for Excellence’ in Scotland outlines a policy vision of a more integrated and holistic form of education; a commitment which offers considerable prospects for increased levels of outdoor learning in schools. With reference to Fullan’s theorizing on achieving educational change, this study investigated four main implementation areas, namely: policy aims, partnerships arrangements, and associated professionalism and sustainability issues. Evidence was collected through a series of 16 semi-structured interviews with key stakeholders at national, local authority, and school level. Despite increased agreement on aims, it was found that improving the frequency and quality of outdoor learning in schools was adversely influenced by the patchwork nature of partnership support at national and local authority levels. This has curtailed the prioritizing of outdoor learning in schools and of teachers being supported when trying to make use of their increased curriculum decision-making responsibilities. Thus, only limited evidence was found of policy-related innovation and considerable evidence of policy stasis. As such, building national capacity is proving difficult. It is concluded that further research on how some atypical schools have managed to develop their programmes offers the best prospects for understanding the complexities of achieving greater levels of outdoor learning.     

Connecting policy aspirations with principled progress? An analysis of current physical education challenges in Scotland

Various recent politically driven policy interventions have outlined the increased importance of school physical education programmes as a contributor towards realising active lifelong learning targets. This paper explains the origins of the new policy emphasis and describes some of the opportunities which now exist for reviewing many curriculum orientation and fragmentation concerns. However, in reviewing the possibilities for policy aspirations to achieve transformative educational benefits, the paper also outlines how a commitment towards principled progress and educational realignment could founder on the rock of its own ambition unless various critical conceptual questions and associated pedagogical issues are thoroughly addressed. Following analysis of the barriers to progress that exist, the encouraging signs of a more coherent future are discussed. This occurs through analysing the progress of developmental-based programmes, which aim to improve the quality and authenticity of pupils’ learning experiences in physical education, and by analysis of the new professional development opportunities that are available to teachers.     

Open learning for continuing education

The two concepts ‐ open learning and continuing education ‐ have recently come to exert a growing influence on educational provision in the United Kingdom. In this article, Malcolm Tight, Director of the Birkbeck Centre for Research and Development in Part‐time Higher Education, considers the interpretation of these concepts and the links between them, both in theory and in practice.
