Children's ideas about ecology 1: theoretical background,design and methodology

Abstract

This paper provides an introduction to a study of the ecological understandings of children aged 5‐16 years in schools in the north of England. Children's ideas about selected ecological concepts were elicited through a series of written tasks and individual interviews set in a range of contexts, referred to here as probes. Responses of about 200 pupils, across the age range, were obtained on each probe. In this paper, issues relating to theoretical background, design and methodology are outlined. Two further papers present the major findings of the study: the first reports children's ideas about the cycling of matter between organisms and between organisms and the abiotic environment (Leach et al. in press a); the second reports children's ideas about the interdependency of organisms in ecosystems (Leach et al. in press b).     

Students’ conceptions and the learning of science

This introductory article to the Special Issue of the International Journal of Science Education attempts to review the theoretical contexts for research into children's conceptions in science and to identify future directions for research programmes in this field.     

Reliability and Validity of Self Report of Aerobic Activity: Family Health Project

Abstract

Two studies are presented which deal with the reliability and validity of self-reports of aerobic activity. The first study compared two forms of self-report data obtained as part of a study of intervention strategy. The two forms were daily self-report and weekly retrospective report. Analyses covering the overlapping time period revealed differences in mean minutes engaged in activity, but modest and statistically significant correlations between the two forms among adults participating in the intervention group. No meaningful results were obtained among adults in the control group, nor among children in either group. The need for the development and testing of self-report forms among children was noted, and was the subject of the second study.

In Study II, six different forms on which third to sixth grade children recorded their aerobic activity were compared against two days of continuous observations of their behavior. The six forms varied along two dimensions. The first dimension varied the time period of reporting: half the forms required reporting by segments of the day; the other half allowed for reporting of the day as a whole. The second dimension varied response format: one third of the forms asked for a dichotomous (yes; no) report; one third asked for a trichotomous (no; yes, but less than 20 min; yes, for 20 min or more) report; and one third asked for reporting of precise numbers of minutes. The segmented day forms resulted in significantly higher agreement with the observers' report of activity. This finding is interpreted to be congruent with recent research on the importance of context in the recall of behavior. No effect from parental assistance in child's form completion was detected.     

Community College Study Abroad: Implications for Student Success

The aim of this research is to explore whether participation in study abroad by community college students impacts levels of engagement and if there is a connection between studying abroad and academic achievement. While university-level studies have a history in exploring these questions, the same is not true for community colleges. The California Community College Student Outcomes Abroad Research project (CCC SOAR) uses a mixed methods design to examine data that evidences how participation in study abroad programs not only has implications for personal development and global learning, but also has a range of indicators of academic success variables. Data show that there is a range of positive outcomes that occur as a result of studying abroad for all students across an array of early, midstream, and terminal outcomes due to engagement-enhancing components such as shared common experiences, nurturing behavior from faculty, and increased student interaction in collaborative activities.     

Evaluating clinical librarian services: a systematic review

Background: Previous systematic reviews have indicated limited evidence and poor quality evaluations of clinical librarian (CL) services. Rigorous evaluations should demonstrate the value of CL services, but guidance is needed before this can be achieved. Objectives: To undertake a systematic review which examines models of CL services, quality, methods and perspectives of clinical librarian service evaluations. Methods: Systematic review methodology and synthesis of evidence, undertaken collaboratively by a group of 8 librarians to develop research and critical appraisal skills. Results: There are four clear models of clinical library service provision. Clinical librarians are effective in saving health professionals time, providing relevant, useful information and high quality services. Clinical librarians have a positive effect on clinical decision making by contributing to better informed decisions, diagnosis and choice of drug or therapy. The quality of CL studies is improving, but more work is needed on reducing bias and providing evidence of specific impacts on patient care. The Critical Incident Technique as part of a mixed method approach appears to offer a useful approach to demonstrating impact. Conclusions: This systematic review provides practical guidance regarding the evaluation of CL services. It also provides updated evidence regarding the effectiveness and impact of CL services. The approach used was successful in developing research and critical appraisal skills in a group of librarians.     

The Systematic Review Team: Contributions of the Health Sciences Librarian

While the role of the librarian as an expert searcher in the systematic review process is widely recognized, librarians also can be enlisted to help systematic review teams with other challenges. This article reviews the contributions of librarians to systematic reviews, including communicating methods of the review process, collaboratively formulating the research question and exclusion criteria, formulating the search strategy on a variety of databases, documenting the searches, record keeping, and writing the search methodology. It also discusses challenges encountered such as irregular timelines, providing education, communication, and learning new technologies for record keeping. Rewards include building relationships with researchers, expanding professional expertise, and receiving recognition for contributions to health care outcomes.     

The Struggle to Democratise German Teacher Education

Abstract

Europe is moving closer to political unity and the introduction of the Single European Act will certainly help promote the professional mobility of teachers. However, modes of teacher education vary enormously from one European country to another and this diversity is likely to militate against mobility, making it difficult for nationals of one country to be fully effective outside their own environment. The present article sets out to analyse the German model of teacher education which, although influential, is complex and, due to the federal structure of the country, not easy to research. It indicates briefly the historical reasons for inequalities of status between teachers of various German school types and describes in general terms the most prevalent current arrangements for producing teachers. These are contrasted with attempts to introduce innovative models likely to lead to greater equality within the teaching profession. The paper then concentrates on efforts made in North Rhine Westphalia and Hesse to reform the traditional structures. The ‘One‐Phase Teacher Education’ programme mounted in Lower Saxony in the 1970s and 1980s is singled out for special attention since it represents the most far‐reaching and radical attempt to date to overhaul German teacher education; its eventual failure reveals that the impediments to reform are deep‐rooted within German society.     

Local management of schools in England: Results after six years

This paper reviews the evidence on the impact of six years of local management of schools in England. Introduced into all parts of the UK except Scotland, as one of the key measures in the Education Reform Act (1988), local management of schools is a particular and limited version of the school‐based management (SBM) model. The paper starts by considering the theoretical basis for the links between SBM and local management on the one hand, and improved school performance in terms of educational outcomes on the other. It then reviews evidence on the impact of local management at the level of the school system, on school management, and against the criteria of efficiency, effectiveness and equity. The findings of research on the impact of local management, in particular the lack of firm evidence of consequential improved educational outcomes for pupils, is then interpreted in terms of the theoretical basis of local management.
