Apparent hyperglycemic and hypoglycemic conditioned responses with exogenous insulin as the unconditioned stimulus

Rats were injected with either insulin or saline and placed in one of two distinctive environments for 25 min on each of several days. On test trials for conditioning, the animals were injected with saline in both environments and blood glucose levels were measured. Apparent conditioned changes were obtained, but the direction of the conditioned response depended upon the environment in which the animals were placed. A conditioned hyperglycemic response occurred in one environment, and a conditioned hypoglycemic response occurred in the other environment. This pattern occurred in both within-subject and between-subjects designs and was not influenced by route of insulin injection (ip or sc). The hypoglycemic, but not the hyperglycemic, response was blocked by methyl atropine. The occurrence of both CR patterns with the same low insulin dose is contrary to previous speculation that the different CR patterns are due to different dose levels of insulin.     

Early Childhood Educators’ Self-Efficacy in Science,Math, and Literacy Instruction and Science Practice in the Classroom

Research Findings: Quality early science education is important for addressing the low science achievement, compared to international peers, of elementary students in the United States. Teachers’ beliefs about their skills in a content area, that is, their content self-efficacy is important because it has implications for teaching practice and child outcomes. However, little is known about how teachers’ self-efficacy for literacy, math and science compare and how domain-specific self-efficacy relates to teachers’ practice in the area of science. Analysis of survey and observation data from 67 Head Start classrooms across eight programs indicated that domain-specific self-efficacy was highest for literacy, significantly lower for science, and lowest for math. Classrooms varied, but in general, engaged in literacy far more than science, contained a modest amount of science materials, and their instructional support of science was low. Importantly, self-efficacy for science, but not literacy or math, related to teachers frequency of engaging children in science instruction. Teachers’ education and experience did not predict self-efficacy for science. Practice or Policy: To enhance the science opportunities provided in early childhood classrooms, pre-service and in-service education programs should provide teachers with content and practices for science rather than focusing exclusively on literacy.     

Promoting a Research Agenda in Education within and beyond Policy and Practice*

Educational research should both inform policy and practice and be forward looking, anticipating the future questions of policymakers, teachers and the community. This paper uses one research organisation, the New Zealand Council for Educational Research (NZCER), as a case study to illustrate possible strategies for promoting research through utilising and building upon research-policymaking and research-practice linkages. It highlights some of the issues, opportunities, and risks for research resulting from the demand for evidence-based policy and from the trend for practitioners to be integral to the research team as research partners and as researchers. It also raises some challenges for research organisations if they are to work effectively both within and beyond the policy and practice parameters of the day.

Reporting on a survey of peer-reviewed publishing in cultural materials conservation: perceptions,preferences, and decision-making

Specialist publications are an important part of professional and disciplinary development. They serve to communicate research; enable the development of a shared, contestable, and expanding knowledge base; support the educational programmes that advance the profession; grow practice; and inform the evolution of the discipline. In conservation, professional and peer-reviewed journals and other forms of publications support cultural, organisational, and scientific development; facilitate new and improved forms of conservation professional practice; enable the growth of a distinctive research-led discipline; and help conservation to more effectively compete with other disciplines for influence and funding. This paper reports on the findings of a study that investigated conservators’ opinions and experiences of peer-reviewed publishing. This study examined the value conservators place on the dissemination of their research; the obstacles to, and incentives in publishing; the views held by conservators of the benefits of publication to themselves and the field; and the impact of the field's inherent interdisciplinarity on the pattern of conservation publishing. Eighty-six conservators (conservators and conservation scientists) and ten journal editors completed an online questionnaire focusing on the communication of knowledge within the field of cultural materials conservation. Findings suggest that while the peer review process is valued, a significant number who responded indicated a preference for forms of communication other than in peer review journals or publishing in general.     

Reducing misinformation effects in children with cognitive interviews: dissociating recollection and familiarity

Two experiments examined the effect of a cognitive interview on 4- and 8-year-old children's correct recall and subsequent reporting of misinformation. Children viewed an event followed by misinformation that was read or self-generated either before or after a cognitive interview. Children were then given a recognition test under inclusion and exclusion instructions. A cognitive interview elicited more correct details than a control interview. Age-related changes were found such that the 8-year-old children's reports were more complete and they recalled more correct person, action, object, and location details than the 4-year-old children. A cognitive interview given after postevent misinformation reduced children's reporting of misinformation at interview and reduced reporting of self-generated misinformation at test. Process dissociation analyses revealed that recollection increased but familiarity decreased with age.     

A genealogy of media studies

This paper seeks to explain why the subject media studies looks and sounds the way it does today through the production of a genealogy of the subject. The questions addressed are first, why was this subject introduced into the curriculum in the 1970s? Secondly, how has knowledge in the subject been defined and contested, how and why has it changed in the course of the subject’s history? Thirdly, which knowledge attains the status of truth and becomes the accepted definition of what the subject is about?The theoretical perspective adopted in this study draws from both postmodernist critiques and sociologies of subject knowledge. It presents a critical sociology of knowledge that draws insights from both social historians of school subjects and the work of Michel Foucault. The study draws a distinction between knowledge as defined by formal educational authorities (articulated in syllabuses) and knowledge defined by those practising the subject (teachers and curriculum advisors).     

Collaborative Partnership: Developing Pre-service Teachers as Inclusive Practitioners to Support Students with Disabilities

Since the introduction of anti-discrimination legislation including Australian Disability Discrimination Act, 1992 and the Disability Standards of Education, 2005, there is an increasing demand on all schools to cater effectively for more students with disabilities within an inclusive school community context. This investigation explored a proactive partnership model designed to equip pre-service teachers with deeper role understandings in teaching students with disabilities. This collaborative model involved sustained professional experiences in schools on four mornings each week over 38 weeks, offered in conjunction with their final-year teacher education studies in Diversity and Inclusive Education. A unique emphasis of this qualitative study was a focus on identifying conducive real-life experiences and ideal teacher qualities for undertaking challenging inclusive practitioner roles. Findings highlighted the perspectives of school leaders, special education mentors and pre-service teachers in improving inclusive learning outcomes for all students while developing an effective collaborative partnership model for teacher education.
