Roda Boa, Roda Boa: Legitimate peripheral participation in diasporic capoeira

Capoeira, the Brazilian dance and martial art, is taught across the world. Learners acquire vital knowledge and are socialised as capoeiristas through legitimate peripheral participation, in particular when watching games in the roda. The roda, the circle within which the capoeira game is played, is a classic place for learning by legitimate peripheral participation to occur. Watching, listening, and feeling the energy of the roda are central to the acquisition of capoeira abilities and capabilities, especially the tacit, indeterminate knowledge and skills.     

Improving the Validity and Reliability of a Health Promotion Survey for Physical Therapists

Purpose

Physical therapists (PTs) have a unique opportunity to intervene in the area of health promotion. However, no instrument has been validated to measure PTs’ views on health promotion in physical therapy practice. The purpose of this study was to evaluate the content validity and test-retest reliability of a health promotion survey designed for PTs.

Methods

An expert panel of PTs assessed the content validity of “The Role of Health Promotion in Physical Therapy Survey” and provided suggestions for revision. Item content validity was assessed using the content validity ratio (CVR) as well as the modified kappa statistic. Therapists then participated in the test-retest reliability assessment of the revised health promotion survey, which was assessed using a weighted kappa statistic.

Results

Based on feedback from the expert panelists, significant revisions were made to the original survey. The expert panel reached at least a majority consensus agreement for all items in the revised survey and the survey-CVR improved from 0.44 to 0.66. Only one item on the revised survey had substantial test-retest agreement, with 55% of the items having moderate agreement and 43% poor agreement.

Conclusions

All items on the revised health promotion survey demonstrated at least fair validity, but few items had reasonable test-retest reliability. Further modifications should be made to strengthen the validity and improve the reliability of this survey.Key Words: health promotion, physical therapy, validity, reliability     

Reporting statistical analyses in peer review journal articles

As a regular referee for the Health Information and Libraries Journal, Richard Stephens – Winner of the 2014 Wellcome Trust Science Writing Prize – has been impressed by the science on offer in the Health Information and Libraries Journal. But he has also been struck by how often similar problems with statistical analysis reporting come up during the review process. Acknowledging that statistics can be scary, he advocates that they should be simply viewed as a means of communicating ideas. In this editorial, he provides some straightforward guidelines on reporting statistical analyses in peer review journal articles, highlights pitfalls to avoid and illustrates best practice to aim for.     

Establishing Influential Decision Making Factors for University Library Opening Hours: An Exploratory UK Regional Study

Many factors and pressures affect decisions made in UK university libraries on opening hours especially 24/7. This article reports on a project to examine the decision making process, influential factors, and stakeholders. A workshop for senior library managers in the East Midlands was held to gather data and share experiences. From analysis of the workshop a framework of influential factors was devised and the decision making process was examined. Although each library had different priorities, important factors overall included pressure from undergraduates and the student's union, and provision during exam periods. Further research to examine the framework nationally is required.     

Model-based reasoning in a year 10 classroom

Studies have shown that secondary school students experience difficulties making scientific models meaningful, yet explanatory models are central to the development of scientific understanding. This study investigated the extent and nature of students' model-based reasoning in a laboratory investigation. It was an interpretive study involving a single Year 10 Science class investigating the influence of six factors on electrical resistance. Before commencing their practical investigations students were re-familiarised with the “electron drift” model of metals. Data sources included videotapes of classroom interactions, audiotaped interviews with students, student workbooks showing their experimental procedures and results, and explanations of those results. The research suggests that spontaneous use of the model in explanations increased over the duration of the task but that the explanations were restricted mainly to model-based reasoning with lower order relational mapping. Even after further formal instruction on the model after the initial experimental investigations, many students were still unable to use the model effectively, displaying mainly the same level of reasoning. As model-based reasoning is an important part of learning some aspects of science, it is imperative that science educators take appropriate steps to facilitate the development of such reasoning in appropriate contexts.     

What Do Educational Mismatches Tell Us About Skill Mismatches? A Cross‐country Analysis

The relationship between higher education and employment is commonly interpreted in terms of the extent to which the higher education sector is providing graduates with the knowledge and skills to match employment needs. It is assumed that a mismatch between working in a job and level or field of education limits the use of skills, with adverse effects on both productivity and earnings. This article examines this assumption on the basis of five countries from the European graduate survey (CHEERS data). Although the analysis shows that educational and skill mismatches are indeed related, mismatches by no means imply mismatches between available and required knowledge and skills. The results indicate that traditional approaches of mismatches have to be adapted to more flexible forms of relationships between higher education and work.
