Socially induced diet preference can partially reverse a LiCl-induced diet aversion

I examined the capacity of a socially induced enhanced diet preference to reverse the effects of a LiCl-induced diet aversion. I found that rats poisoned after eating a novel diet (Diet NPT) would consume substantial amounts of Diet NPT following interaction with a conspecific that had eaten Diet NPT. Neither rats interacting with a conspecific fed some other diet nor rats exposed to Diet NPT itself exhibited reduced aversion to Diet NPT. This surprising capacity of social interaction to ameliorate even profound toxicosis-induced aversions suggests that social influence may be a major experiential determinant of the diet preferences of free-living rats.     

More than a picture: helping undergraduates learn to communicate through scientific images

Images are powerful means of communicating scientific results; a strong image can underscore an experimental result more effectively than any words, whereas a poor image can readily undermine a result or conclusion. Developmental biologists rely extensively on images to compare normal versus abnormal development and communicate their results. Most undergraduate lab science courses do not actively teach students skills to communicate effectively through images. To meet this need, we developed a series of image portfolio assignments and imaging workshops in our Developmental Biology course to encourage students to develop communication skills using images. The improvements in their images over the course of the semester were striking, and on anonymous course evaluations, 73% of students listed imaging skills as the most important skill or concept they learned in the course. The image literacy skills acquired through simple lab assignments and in-class workshops appeared to stimulate confidence in the student's own evaluations of current scientific literature to assess research conclusions. In this essay, we discuss our experiences and methodology teaching undergraduates the basic criteria involved in generating images that communicate scientific content and provide a road map for integrating this curriculum into any upper-level biology laboratory course.     

If I had a magic wand I'd magic her out of the book: the rich literacy practices of competent early readers

This article explores the reading behaviours of 10 young competent nursery and reception children, The 10 children were selected from a group of 54 case study children involved in the national Bookstart evaluation study, Bookstart: Planting a Seed for Life (2005). This group of young readers, from different socioeconomic groups, were identified as reading in advance of their peers. The first part of this article explores the children's attitudes to reading, their responses to selected texts and their understanding of early phonological and letter knowledge. Second, the article reports on the findings from interviews with the parents of these children in order to illuminate the home literacy events that shape these young children's reading competences. This article is based on the larger scale national evaluation study of the Bookstart project, Bookstart: Planting a Seed for Life (2005). The evaluation was set up to explore the effectiveness of the Bookstart programme and the impact of early book giving on the first national cohort of Bookstart children as they entered school.

Children's Understanding of Knowledge Acquisition: The Tendency for Children to Report That They Have Always Known What They Have Just Learned

Children's attention to knowledge-acquisition events was examined in 4 experiments in which children were taught novel facts and subsequently asked how long they had known the new information. In Experiment 1, 4- and 5-year-olds tended to claim they had known novel animal facts for a long time and also reported that other children would know the novel facts. This finding was replicated in Experiment 2, using facts associated with chemistry demonstrations. In Experiments 3 and 4, children were taught new color words. 5-year-olds, but not 4-year-olds, distinguished between novel and familiar color words, reporting they had not known the novel words before the test session, but they had always known the familiar words. 4-year-olds in Experiment 4 were better able to distinguish novel and familiar color words when the teaching of the novel words was an explicit and salient part of the procedure.     

A critical appraisal of four approaches which support teachers’ problem‐solving within educational settings

This paper critically appraises four problem‐solving approaches, based on a range of theoretical perspectives and procedures, which are currently used in educational settings to support adults to find solutions to complex problems that arise within classrooms and the wider school community. The four approaches are: Circles of Adults; Teacher Coaching; Collaborative Problem‐solving Groups; the Staff Sharing Scheme. The principle aim of all of these interventions is to enable school staff to generate solutions to problems so that children and young people who are causing concern are perceived in ways which lead to more constructive actions and outcomes. A second aim is to build the capacity of those working in schools by developing their skills and self confidence as problem‐solvers and decision‐makers; the assumption being that they will be more able to solve similar problems in the future largely on their own, without the need for extensive external support. The paper then considers the relative strengths and limitations of each approach in relation to practice.     

Challenges presented to personal theories,beliefs and practices of play in Abu Dhabi kindergartens: the English Medium teacher perspective

Abu Dhabi Education Council’s new school model recognizes the value of play, although anecdotal evidence suggests that there are challenges to play in the preschool context. This article reports on challenges from the English Medium teacher perspective. Findings show that challenges are related to: (a) children meeting teacher expectations for play which may be limited by: real-life exposure, the nanny’s role, a desert climate for outdoor play, overuse of technology; and English as an additional language; (b) acquiring adequate resources for play, including open-access to Internet sites, meaning teachers have to use their own money to provide resources for play; (c) establishing boundaries and managing behaviour, especially for boys; (d) working with conflicting time pressures caused by academic performance benchmarking, accountability and workload; and (e) working with diversity, including meeting parental expectations, collaborating with colleagues and understanding the cultural and linguistic background of children. Recommendations to lessen the challenges of nurturing appropriate play experiences are made within the context of the findings.     

Narratives from the road to social justice in PETE: teacher educator perspectives

Developing teacher education programmes founded upon principles of critical pedagogy and social justice has become increasingly difficult in the current neoliberal climate of higher education. In this article, we adopt a narrative approach to illuminate some of the dilemmas which advocates of education for social justice face and to reflect upon how pedagogy for inclusion in the field of physical education (PE) teacher education (PETE) is defined and practiced. As a professional group, teacher educators seem largely hesitant to expose themselves to the researcher's gaze, which is problematic if we expect preservice teachers to engage in messy, biographical reflexivity with regard to their own teaching practice. By engaging in self- and collective biographical story sharing about ‘our’ teacher educator struggles in England and Norway, we hope that the reader can identify ‘her/his’ struggles in the narratives about power and domination, and the spaces of opportunity in between.     

RESEARCH REPORT

The study explores teachers’ experiences of teaching a context‐based chemistry course, Salters Advanced Chemistry, as compared with teachers of a conventional course. Second, main factors that appear to influence decisions over whether or not to adopt context‐based courses are investigated. Two hundred and twenty‐two teachers’ views of a context‐based and a conventional school advanced chemistry course were obtained from a questionnaire. Responses were analysed in six dimensions: motivation, chemical knowledge and development of concepts, learning activities, assessment, challenge to teachers and students, and teacher support. Both sets of teachers agreed that the context‐based course is more motivating to study and teach, that students would be more interested in chemistry and more likely to go to university to study chemistry, that students would be better able to study independently but that it is more demanding to teach and study. The groups differed principally about concept development and teaching strategy. The context‐based teachers believed that their course gave as good a foundation for further study as a traditional course and that the spiral curriculum was advantageous. Conventional course teachers disagreed with both statements. One significant implication to emerge from the study is the crucial role played by in‐service support in influencing the impact of a curriculum innovation.
