Overnight incubation of a partially conditioned eyeblink response in rabbits

Three experiments employing the rabbit eyelid conditioning paradigm examined the effect of a variable-duration rest period on the performance of a partially acquired CR. Conditioning performance improved as a direct monotonic function of the retention interval. Performance after a 24-h rest interval was substantially superior to that observed after a rest interval of several minutes. The third experiment indicated that fatigue factors may be an important factor in producing this incubation effect.     

Climate change, flooding and the media in Britain

The weather is a preoccupation of the British public, and flooding has become a salient feature of their experience. Climate science also has important things to say about the prevalence, distribution and dangers of rainfall and flooding, and what we should expect from global warming. This paper looks at British press coverage of flooding, and at the connections made between this theme and climate change. It aims to expose longitudinal patterning, and assess how common the connection is. From here the analysis moves to specific cases of high profile flooding events for a detailed exploration of the tone and tenor, and discursive contours of reports. The results suggest the media's contribution to genuine debate is mixed, that the connection between common forms of reportage and our scientific understanding of the phenomena is often tenuous. The paper explores the implications for the way the politics of climate change plays out.     

Contextualising higher education assessment task words with an ‘anti-glossary’ approach

Key ‘generic’ assessment task words such as ‘discuss’ and ‘critically evaluate’ are integral to higher education assessment. Although sources such as study skills guides give generic decontextualised glossaries of these words, much research rightly argues for greater dialogue between students (particularly ‘non-traditional’ students) and lecturers to help students understand and use such words. This paper presents the results from ‘staged’ focus groups with lecturers and students from the UK and China that created a forum for such dialogue, where many of these words and their interpretations were talked about. Results show very different interpretations, informed by factors such as ‘language’, ‘culture’ and ‘subject’. We propose these factors be used in an ‘anti-glossary’ approach, which we describe here. This approach is not against glossaries per se, but counteracts the assumption that glossary definitions are explicit, and adopts a social constructivist contextualisation of the task words through teacher-led dialogue.     

Identifying the value of data analytics in the context of government supervision: Insights from the customs domain

eCommerce, Brexit, new safety and security concerns are only a few examples of the challenges that government organisations, in particular customs administrations, face today when controlling goods crossing borders. To deal with the enormous volumes of trade customs administrations rely more and more on information technology (IT) and risk assessment, and are starting to explore the possibilities that data analytics (DA) can offer to support their supervision tasks. Driven by customs as our empirical domain, we explore the use of DA to support the supervision role of government. Although data analytics is considered to be a technological breakthrough, there is so far only a limited understanding of how governments can translate this potential into actual value and what are barriers and trade-offs that need to be overcome to lead to value realisation. The main question that we explore in this paper is: How to identify the value of DA in a government supervision context, and what are barriers and trade-offs to be considered and overcome in order to realise this value? Building on leading models from the information system (IS) literature, and by using case studies from the customs domain, we developed the Value of Data Analytics in Government Supervision (VDAGS) framework. The framework can help managers and policy-makers to gain a better understanding of the benefits and trade-offs of using DA when developing DA strategies or when embarking on new DA projects. Future research can examine the applicability of the VDAGS framework in other domains of government supervision.     

Queensland teachers’ conceptions of assessment: The impact of policy priorities on teacher attitudes

The conceptions Queensland teachers have about assessment purposes were surveyed in 2003 with an abridged version of the Teacher Conceptions of Assessment Inventory. Multi-group analysis found that a model with four factors, somewhat different in structure to previous studies, was statistically different between Queensland primary and (lower) secondary teachers. Primary teachers agreed more than secondary teachers that ‘assessment improves teaching and learning’, while the latter agreed more that it ‘makes students accountable’. The inter-correlation of ‘assessment is irrelevant’ to ‘makes students accountable’ was statistically stronger for primary teachers. Teacher beliefs reflected the differing practices of assessment by level of schooling.     

Changing organizational culture and instructional methods in elementary schools: Perceptions of teachers and professional educational consultants

The present study examines teachers’ perceptions of organizational changes in their elementary schools. These changes occurred following the implementation of a long-term comprehensive school improvement project (CSIP). One hundred and seventy one teachers who taught in six elementary schools located in two different school districts in Israel responded to a questionnaire both before and after a period of 3 years during which they participated in a CSIP. The teachers, assisted by six professional consultants, one in each school, studied cooperative learning as well as new forms of collaborative staff work. The study addressed two primary research questions: What changes in teachers’ perceptions of their schools’ organizational culture emerged from teachers’ participation in the project? How were the professional relationships between the schools’ supervisors and the teachers in the two districts reflected in the teachers’ perception of school organizational changes? Results indicated that teachers in three schools from one district recorded a significant improvement in their perceptions of their schools’ organizational culture at the end of the project, whereas the teachers from the other district indicated either no change, or a significant decline in their evaluation of their schools’ organizational culture. A cross-validation of the teachers’ data was performed through a content analysis of 500 reports written over the course of 2 years, submitted by six external consultants. The analysis yielded four categories: general difficulties to work with the school’s staff, problems implementing the project, teacher resistance, and cancellations of planned meetings. The analysis provided valuable information as to why the teachers from the two districts differed in their reactions to the project.     

Children of Alcoholics in the schools: Where are they? their representation in special education

The hypothesis that there is a greater frequency of children of alcoholics in special classes for Emotional/Behavioral Disordered (ED) and Learning Disabled (LD) children was explored. A random sample of students in ED, LD, and regular classes was selected and administered the Children of Alcoholics Screening Test. Parents completed the Friel Co-Dependency Assessment Inventory. An analysis of variance in CAST and FCAI scores did not reveal any significant differences among groups. Significant differences were noted in the relationship of marital status and chemical dependency in immediate family. Reported incidence of chemical dependency in the immediate family was identified as a concern warranting further exploration. Issues that may have affected the study such as sample size, respondent participation, and various roles exhibited in the family were considered. The possible impact alcoholism has on children and appropriate program intervention in the schools were discussed.     

‘Learning the basics’: young people’s engagement with sexuality education at secondary schools

School-based sexuality education remains a key response to the HIV epidemic. Drawing on findings from an ethnographic study, this study explores how young people engage with sexuality and HIV- and AIDS-related education as it is delivered through the Life Orientation (LO) learning area in South Africa, in order to understand the dynamics that support or hinder engagement. Focus group discussions were held with Grade 9 and 11 learners (aged 14–18 years) from 16 randomly selected public secondary schools across three provincial districts. Results show that enjoyment of LO education was related to perceived relevance and distinctiveness, informal lesson delivery, subjective assessment standards and seemingly minimal effort. However, the perception of reduced effort tarnished the status of LO and young people’s motivation to participate. Learner engagement is influenced by a variety of cognitive, affective and behavioural pathways including internalised discourse around HIV and AIDS, gender and sexuality; the quality of youth–educator relations and teaching competencies; peer pressures; and broader cultural dynamics. The cultivation of a learning environment in which young people share and debate their views promotes engagement and critical thinking. In-service and pre-service educator training, structured activity plans and monitoring are recommended to advance the content knowledge and pedagogy of educators.     

The effect of high-stakes examination systems on teacher beliefs: Egyptian teachers’ conceptions of assessment

Egypt is currently attempting to introduce a greater formative use of assessment while maintaining a public examination system. This study investigates teacher beliefs about the purposes of assessment in Egypt, using the Teachers’ Conceptions of Assessment (TCoA) inventory. The TCoA inventory elicits responses about four main factors: Improvement, School Accountability, Student Accountability and Irrelevance. A large sample of (n?=?507) Egyptian pre-service and in-service teachers completed an Arabic version of the TCoA inventory. Confirmatory factor analysis was used to test the Egyptian teachers’ responses against the pre-existing New Zealand model, which was found to be inadmissible. Consequently, an ecologically rational three-factor model was found. The model yielded a strong positive relationship between Improvement and Student Accountability, consistent with previous studies. It is argued that greater changes to the examination system are required if teacher beliefs are expected to be more positive about the priority of formative, improvement-oriented uses of assessment.
