Children with asthma: Assessment and treatment in school settings

Asthma is a chronic disease of the airways. It affects approximately 12% of American children, and it appears that that incidence is increasing. Asthma in children negatively influences school‐based outcomes such as absenteeism and friendship formation. Potential triggers of asthma include environmental allergens, exercise, weather, and emotional states. These lead to airway swelling and muscle constriction, which ultimately block airflow and impede breathing. In addition to medical treatments, the implementation of psychologically based interventions has been efficacious in school settings. © 2007 Wiley Periodicals, Inc.     

The 'empowerment' of students: a contribution from systemic functional grammar

Since there is no single pedagogical theory that may provide all necessary strategies for the successful teaching of academic essay writing at senior levels, this paper makes a small but hopefully interesting contribution from the basis of Systemic Functional Grammar. It is intended to supplement teachers’ insights into the linguistic characteristics of academic writing considered ‘Excellent’, as much as to offer strategies for empowering students with a clearer idea of what is expected of them in academic writing. It attempts this by making explicit some of the grammatical choices made by successful writers, and how those choices facilitate the presentation of knowledge and ideas in ways that fulfil the expectations readers (and examiners) have of merit‐worthy writing.     

The Disruptive Qualities of Linked Data in the Library Environment: Analysis and Recommendations

Libraries are looking for a better way to encode and share their data. Christensen's disruptive technologies theory provides a framework for evaluating linked data and thinking about future uses of library technology. Because of its lack of use and technical weaknesses, linked data is not yet poised to emerge as a disruptive innovation. It has the potential, however, to become disruptive and should be explored first in spin-offs that supplement library data or provide access to other electronic content. Library systems under development should focus on remaining nimble and open to unforeseen future technologies and uses.     

Rogues of the Racecourse

This article focuses on the reporting of racecourse crime, exploring the shifting cultural contexts in which the press constructed outbreaks of metropolitan gang-related crime. The first part of the article looks at the extended coverage of what became known as the ‘racecourse wars’, concentrating on three key themes which permeate the accounts of racecourse crime between 1920 and 1925: the organisation of crime, the use of firearms and the mobility of criminals. The coverage of these events, which can be traced across a number of different newspapers, was often described in ways that reflected concerns about the organisation and professionalisation of crime. After 1925, despite continuing outbreaks of violence and racecourse-related crime, the press coverage subsided. However, in 1936 the racing men once again became ‘folk devils’, and the final part of the article explores the re-emergence of press reportage by considering the responses to the Lewes Racecourse Affray in June 1936. In this latter period, the rising influence of the American gangster film (as well as coverage of events in American cities such as New York and Chicago) meant that a newer language of gangsterdom would become increasingly embedded in British cultural forms.     

Operation ARA: A computerized learning game that teaches critical thinking and scientific reasoning

Operation ARA (Acquiring Research Acumen) is a computerized learning game that teaches critical thinking and scientific reasoning. It is a valuable learning tool that utilizes principles from the science of learning and serious computer games. Students learn the skills of scientific reasoning by engaging in interactive dialogs with avatars. They are tutored by avatars with tutoring sessions that vary depending on how well students have responded to questions about the material they are learning. Students also play a jeopardy-like game against a feisty avatar to identify flaws in research and then generate their own questions to determine the quality of different types of research. The research examples are taken from psychology, biology, and chemistry to help students transfer the thinking skills across domains of knowledge. Early results show encouraging learning gains.     

Using targeted active-learning exercises and diagnostic question clusters to improve students' understanding of carbon cycling in ecosystems

In this study, we used targeted active-learning activities to help students improve their ways of reasoning about carbon flow in ecosystems. The results of a validated ecology conceptual inventory (diagnostic question clusters [DQCs]) provided us with information about students' understanding of and reasoning about transformation of inorganic and organic carbon-containing compounds in biological systems. These results helped us identify specific active-learning exercises that would be responsive to students' existing knowledge. The effects of the active-learning interventions were then examined through analysis of students' pre- and postinstruction responses on the DQCs. The biology and non-biology majors participating in this study attended a range of institutions and the instructors varied in their use of active learning; one lecture-only comparison class was included. Changes in pre- to postinstruction scores on the DQCs showed that an instructor's teaching method had a highly significant effect on student reasoning following course instruction, especially for questions pertaining to cellular-level, carbon-transforming processes. We conclude that using targeted in-class activities had a beneficial effect on student learning regardless of major or class size, and argue that using diagnostic questions to identify effective learning activities is a valuable strategy for promoting learning, as gains from lecture-only classes were minimal.     

Correlates of problem recognition and intentions to change among caregivers of abused and neglected children

OBJECTIVE: To identify individual, family, and caseworker characteristics associated with problem recognition (PR) and intentions to change (ITC) in a sample of caregivers who received in-home child welfare services following substantiated reports of child abuse or neglect. METHODS: Caregivers were interviewed at 4 weeks, 16 weeks, and 1 year after referral for in-home services. In these interviews, the University of Rhode Island Change Assessment scale assessed PR and ITC in relation to caregiving practices. Additional data were obtained from administrative records and surveys of in-home services caseworkers. We used growth models to identify caregiver, family, and caseworker characteristics associated with initial levels of PR and ITC, and with changes in PR and ITC over time. RESULTS: Contrary to expectations, there were no overall increases in PR and ITC during the first 4 months of in-home services. PR and ITC scores fluctuated over time, in relation to some external events, case characteristics, and caseworker characteristics; however, we were able to account for small portions of the variance in PR and ITC. Controlling for social desirability bias and other variables in the analysis, negative life events, lack of network support, and the severity of caregiver depression were associated with greater PR; housing problems were associated with lower PR. Caregiver depression and age were associated with ITC. Caregivers whose children had been removed from their homes showed significant increases in ITC in the first few months of in-home services. The duration of caseworkers' child welfare experience predicted increases in their clients' PR in the first 4 months and more frequent contacts with an experienced caseworker predicted small, but significant increases in ITC over time. CONCLUSIONS: PR and ITC are associated with somewhat different case characteristics and may be affected by caseworkers' experience.     

Achievement and Growth on English Language Proficiency and Content Assessments for English Learners in Elementary Grades

English language proficiency (ELP) assessment scores are used by states to make high-stakes decisions related to linguistic support in instruction and assessment for English learner (EL) students and for EL student reclassification. Changes to both academic content standards and ELP academic standards within the last decade have resulted in increased academic rigor and language demands. In this study, we explored the association between EL student performance over time on content (English language arts and mathematics) and ELP assessments, generally finding evidence of positive associations. Modeling the simultaneous association between changes over time in both content and ELP assessment performance contributes empirical evidence about the role of language in ELA and mathematics development and provides contextual information to serve as validity evidence for score inferences for EL students.
