iSpot: a citizen science platform for inclusive learning and teaching
www.iSpotnature.org (iSpot) is an Open University (OU) citizen science platform launched in 2009, which uses the challenge of identifying nature to engage people as citizen scientists. It encourages learning about wildlife while building species identification skills. iSpot has an active online community and provides a multifaceted experience, incorporating participatory science research with e-learning opportunities. Learning was always part of the design, with innovative educational technology based tools and features incorporated along with activities which encourage public participation and engagement that help to facilitate teaching; creating a unique learning journey. This poster shares best practice of an initiative that demonstrates how citizen science can act as a platform for scientific literacy. It demonstrates how iSpot supports informal to formal learning through a five-step model: explore, identify, contribute, personalise and recognition. It shares how the integration of authentic inquiry, through a citizen science platform environment, facilitates learning; and highlights this through the development a new course Global biodiversity and citizen science
A stress free model for residual stress assessment using thermoelastic stress analysis
Thermoelastic Stress Analysis (TSA) has been proposed as a method of obtaining residual stresses. The results of a preliminary study demonstrated that when Al-2024 plate containing holes that were plastically deformed by cold expansion process to 2% and 4% strain the thermoelastic response in the material around the hole was different to that obtained from a plate that had not experienced any plastic cold expansion (i.e. a reference specimen). This observation provides an opportunity for obtaining residual stresses based on TSA data. In many applications a reference specimen (i.e. residual stress free specimen) may not be available for comparison, so a synthetic, digital bitmap has been proposed as an alternative. An elastic finite element model is created using commercially available software Abaqus/Standard and the resultant stress field is extracted. The simulated stress field from the model is mapped onto a grid that matches the TSA pixel data from a physical reference specimen. This stress field is then converted to a ?T/T field that can be compared to the full-field TSA data. When the reference experimental data is subtracted from the, bitmap dataset the resultant ?T/T field is approximately zero. Further work proposes replacing the experimental reference data with that from specimens that have undergone cold expansion with the aim of revealing the regions affected by residual stress through a departure from zero in the resultant stress field. The paper demonstrates the first steps necessary for deriving the residual stresses from a general specimen using TSA

Operation Iraqi freedom and mental health of Vietnam veterans
The purpose of this study was to provide a clear conceptualization of how Vietnam veterans who have previously been diagnosed with PTSD (Post Traumatic Stress Disorder) respond and cope with the emotional and psychological effects presented by the present war in Iraq

Parents....an Invaluable Link to Student Success
Research demonstrates the strong correlation between parental involvement and student achievement. This research, which involves studies that highlight the outcomes of parental involvement, will be presented. In addition, examples of parental involvement from tiers 1, 2, and 3 in the various PBIS systems in northwest Georgia will be given. Haralson County Schools will provide specific examples on how they have included not only parents, but also community stakeholders in their quest to increase participation. They will discuss specific strategies on how to engage parent/community stakeholders on a limited budget. Participants will walk away with ideas and strategies that have been successful in seven PBIS systems in northwest Georgia
Drugs associated with prescribing errors in older patients in two English general practices
Medication errors have the potential to cause patient morbidityand mortality, and increase pressure on healthcare. Studies haveindicated that older patients may be more susceptible tosignificant risks of harm from prescribing errors1,2, though thereis a dearth of research in this patient group.Peer reviewe
Profiles of learning. The Basic Skills Testing Program in New South Wales 1989
The 1989 Basic Skills Testing Program in New South Wales provides the most comprehensive picture yet compiled of literacy and numeracy learning in Australian primary schools. In 1989, some 53,800 Year 6 students in NSW government schools were tested in five aspects of literacy and numeracy. Another 2,300 Year 3 students took part in a pilot study. This book discusses the writing of the tests, the analysis of results, and the reporting of results to parents, teachers and schools. The aim of the basic skills tests is to describe, in positive terms, the skills that students have mastered, to identify areas in which students have special strengths and weaknesses, and to provide guides to further learning. The picture that emerges from this study is of widespread success in learning. The results point to much good teaching and a fine start in learning for most primary students. But this generally optimistic picture is over shadowed by the performances of some students who have not yet mastered essential Year 6 skills. Part I of the book describes the skills typical of students performing at each of five skill levels in each of five areas of learning (Reading, Language, Number, Measurement, and Space) on the tests. Part II shows how different subgroups of students performed on the tests. Results on each aspect of literacy and numeracy are reported separately for girls and boys, students with non-English-speaking backgrounds, Aboriginal and Torres Strait Islander students, and several age groupings. Part III explains and gives examples of reports mailed to parents, more detailed reports given to teachers, and summary tables generated for each school. Part IV describes procedures used to develop BSTP tests and to analyze students\u27 results in preparation for reporting. Numerous test items are presented
