The Role of Outcome and Experience in Hypothesis Testing about Food Allergy

It is important to understand the reasoning strategies that health behaviours are based on. Croker and Buchanan (2011b) found that the strategies people use when choosing how to test a hypothesis about oral health are affected by whether the participant is seeking to reproduce a positive outcome (i.e., good health) or eliminate an unwanted outcome (i.e., bad health). The aim of this study was to investigate the effect of outcome on reasoning strategies in a food allergy context. Participants with and without food allergy were given hypothesistesting tasks and asked to choose which of three alternative patterns of food consumption could be used to test a hypothesis that a person is allergic to a particular food. Participants were more likely to select a controlled test of the hypothesis that a specific food causes an allergic reaction when a reaction to a food had been observed after eating, than when a reaction had not been observed due to food avoidance. Although the potential severity of making an incorrect choice in a food allergy context is both greater and more proximal than in an oral health context, the same bias in reasoning strategy was found. Logically appropriate hypothesis-testing behaviour may not, therefore, underpin real-world decision making

Residential Chemistry Camps for School Students:Why Bother?

Bristol ChemLabS has been providing several residential school experiences per year for the past eight years. The Chemistry Camps are two days of intensive activity and, wherever possible, involve a stay in a hall of residence. The majority of the time is spent in undergraduate teaching laboratories learning new skills on the first day, which are then used again on the second. The other academic sessions include spectroscopy tours, short lectures from postgraduate students on their research areas, a discussion of university application procedures in general by admissions officers and a lecture demonstration. The non-academic side is also addressed via a stay in a hall of residence and a course dinner. The purpose of this paper is to discuss the organisation and running of such camps and to explore the benefits for both the students and the School of Chemistry

Scoping the impact of the national child measurement programme feedback on the child obesity pathway: study protocol.

BACKGROUND: The National Child Measurement Programme was established to measure the height and weight of children at primary school in England and provides parents with feedback about their child's weight status. In this study we will evaluate the impact of the National Child Measurement Programme feedback on parental risk perceptions of overweight, lifestyle behaviour and health service use. METHODS: The study will be a prospective cohort study of parents of children enrolled in the National Child Measurement Programme and key service providers from 5 primary care trusts (administrative bodies responsible for providing primary and secondary care services). We will conduct baseline questionnaires, followed by provision of weight feedback and 3 follow up questionnaires over the course of a year. Questionnaires will measure change in parental risk perception of overweight, health behaviours and health service use. Qualitative interviews will be used to identify barriers and facilitators to change. This study will produce preliminary data on National Health Service costs associated with weight feedback and determine which feedback approach (letter and letter plus telephone) is more effective. DISCUSSION: This study will provide the first large scale evaluation of the National Child Measurement Programme feedback. Findings from this evaluation will inform future planning of the National Child Measurement Programme.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Teaching the control-of-variables strategy: A meta-analysis

A core component of scientific inquiry is the ability to evaluate evidence generated from controlled experiments and then to relate that evidence to a hypothesis or theory. The control-of-variables strategy (CVS) is foundational for school science and scientific literacy, but it does not routinely develop without practice or instruction. This meta-analysis summarizes the findings from 72 intervention studies at least partly designed to increase students\u27 CVS skills. By using the method of robust meta-regression for dealing with multiple effect sizes from single studies, and by excluding outliers, we estimated a mean effect size of g = 0.61 (95% CI = 0.53–0.69). Our moderator analyses focused on design features, student characteristics, instruction characteristics, and assessment features. Only two instruction characteristics – the use of cognitive conflict and the use of demonstrations – were significantly related to student achievement. Furthermore, the format of the assessment instrument was identified as a major source of variability between study outcomes. Implications for teaching and learning science process skills and future research are discussed
