The reluctant primary school teacher

The study attempts to identify the factors which affect teacher's reluctance to teach science, then explains an approach to help teachers teach science in a worthwhile manner over the school year while monitoring any changes in their confidence and competence. It was found that the condidence and competence of the teachers improved during the year such that they were able to teach successful science lessons on a regular basis.

Shipping in the Northwest Passage: a Pandora's box

The discovery of America led to dreams of a westerly route to India and China from Europe by way of its most northerly extension. Evidence for the existence of such a route was laboriously collected by explorers from the time of Frobisher in the late 16th century but not until 1903-6 was a full west-to-east passage effected, by Roald Amundsen. Today, interest in the Northwest Passage has been stimulated by the discovery of oil and gas in far northern latitudes and new technology is facilitating commercial voyages in these exceptionally inhospitable waters.     

Using matrix norms to estimate the direction of arrival of planar waves on an ULA

SEAD method estimates the direction-of-arrival angles on an uniformly linear array based on the difference between the two largest singular values, what is called differential spectrum. Although it presented an outstanding performance, the ability to indicate the source positions was not elucidated yet. Inspired by the differential spectrum formulation we derived a total differential spectrum and found out that the matrix norm induced by the vector 2-norm of a modified spatial covariance matrix can be used to estimate the direction-of-arrival of multiple plane waves. Indeed we show that matrix norms are estimators and we propose their use instead of the singular value decomposition in SEAD-based methods. We present a general mathematical expression in order to explicit the operating principles of the proposed methods. Consequently, we were able to explain how the relation between the arriving and the search angles produces the larger peaks on the differential spectrum. To evaluate the important role played by matrix norms, a thousand experiments were carried out. They showed that the proposed approach proved to be as accurate as the previous SEAD-based methods, while providing a significant reduction on runtime. It also outperformed well-established methods like MODEX regarding the estimation error.     

Embracing New Policies,Technologies, and Community Partnerships: A Case Study of the City of Houston's Bureau of Air Quality Control

As the City of Houston's Bureau of Air Quality Control embraced new policies, technologies, and rhetorical strategies, they simultaneously moved through Lukensmeyer and Torres's “four levels of public involvement,” which include the information, consultation, engagement, and collaboration levels (Lukensmeyer & Torres, 2006 Lukensmeyer, C. J., & Torres, L. H. (2006). Public deliberation: A manager's guide to citizen engagement. IBM Center for the Business of Government Collaboration Series. Retrieved November 2007 from http://www.businessofgovernment.org/pdfs/LukensmeyerReport.pdf  [Google Scholar]). Because of the technical and scientific nature of air quality inspections, increasing public involvement, especially the involvement of those in a predominantly African American and a predominantly Hispanic neighborhood, has been a challenge. This article describes the Bureau's journey through the information level, where the Bureau opens public access and participation in the investigation and reporting process; the consultation level, where Bureau staff go door-to-door in poor and minority neighborhoods collecting citizen feedback regarding perceived environmental hazards; the engagement level, where the Bureau conducts monthly environmental meetings with neighborhood residents; and the collaboration level, where citizens are taught to collect evidence of environmental violations.     

Analysis of the body composition of Paralympic athletes: Comparison of two methods

Body composition is a physiological variable associated with physical activity and, in some cases, is related to athletic performance. Our objectives were to describe the body composition of participants in three distinct Paralympic sports and to compare the values of body density and estimated body fat obtained from the Paralympic athletes on the National Team by air-displacement plethysmography (ADP) and by the anthropometric method (skinfolds (SFs)). The sample consisted of 70 volunteers of both genders. The body composition of the volunteers was evaluated using the ADP in a Bod Pod^® and seven SFs. There were no significant differences between the values obtained by ADP and SF for body fat percentage (p?=?.58) and body density (p?=?.49). Analysis by Bland–Altman plots showed mean differences of 0.56?±?4.94 (?9.12–10.23) and ?0.0017?±?0.0113 (?0.024–0.020) for body fat percentage and body density, respectively. In conclusion, body composition analyses of Paralympic athletes by the ADP and SF methods show similar results, and ADP should be used as the first option when available. When the use of ADP is not possible, estimating body density and fat percentage by SF is a viable alternative for Paralympic athletes when future comparisons will use the same analysis method.     

“UNIFIED”: Bridging the Researcher–Practitioner Divide in Mind,Brain, and Education

Mind, Brain, and Education (MBE) science is by definition transdisciplinary. However, the communication and collaboration between constituent disciplines needed for true transdisciplinarity remains relatively rare. Consequently, many of the potential benefits of MBE science remain unrealized for parties on all sides of the discipline. The present commentary first conducts an analysis of the current strengths, weaknesses, opportunities, and threats of transdisciplinary partnerships in MBE. A new, free, and international web platform (“UNIFIED”) is then proposed to broker relationships between researchers and teachers within schools. This website would allow users to form collaborations based on a system of tags indexing their research interests as well as practicalities such as their location. Such a website appears well placed to realize many of the opportunities, and mitigate the threats and weaknesses, of transdisciplinary MBE research. The article concludes with an appeal to interested researchers and schools to contribute to the development of the project.     

Outcomes and satisfaction of two optional cadaveric dissection courses: A 3‐year prospective study

Teaching time dedicated to anatomy education has been reduced at many medical schools around the world, including Nova Medical School in Lisbon, Portugal. In order to minimize the effects of this reduction, the authors introduced two optional, semester‐long cadaveric dissection courses for the first two years of the medical school curriculum. These courses were named Regional Anatomy I (RAI) and Regional Anatomy II (RAII). In RAI, students focus on dissecting the thorax, abdomen, pelvis, and perineum. In RAII, the focus shifts to the head, neck, back, and upper and lower limbs. This study prospectively analyzes students' academic achievement and perceptions within the context of these two, newly‐introduced, cadaveric dissection courses. Students' satisfaction was assessed anonymously through a questionnaire that included items regarding students' perception of the usefulness of the courses for undergraduate teaching, as well as with regards to future professional activity. For each of the three academic years studied, the final score (1 to 20) in General Anatomy (GA), RAI, and RAII was on average 14.26 ± 1.89; 16.94 ± 1.02; 17.49 ± 1.01, respectively. The mean results were lower in GA than RAI or RAII (P < 0.001). Furthermore, students who undertook these courses ranked them highly with regards to consolidating their knowledge of anatomy, preparing for other undergraduate courses, and training for future clinical practice. These survey data, combined with data on participating students' academic achievement, lend strong support to the adoption of similar courses as complementary and compulsory disciplines in a modern medical curriculum.

Learning to learn in informal science settings

Visits to museums and science centres are a part of most school science programs- but are they really learning experiences? By accompanying classes on visits and talking with the teachers and students during and after these visits, information has been gathered on the ways in which school groups currently use visits to two informal science learning settings in Sydney- a science education centre and a large museum. Comparison of the teacher and student behaviours on these visits with current views on good teaching/learning practice, reveals considerable anomalies. At the same time, reported studies of museum visitors suggest that family groups use museums for learning in ways which are quite different from the way most school groups do. Can these apparent mismatches be translated into a pathway for developing new approaches to learning in informal settings?
