Rational Higher-Order Belief Revision in Young Children

Belief revision can occur at multiple levels of abstraction, including lower-level and higher-order beliefs. It remains unclear, however, how conflicting evidence interacts with prior beliefs to encourage higher-order belief revision. This study explores how 4- and 5-year-olds (N = 96) respond to evidence that directly conflicts with their causal higher-order beliefs. When shown a single event that directly violated a strongly supported prior belief, preschoolers largely maintained their initial higher-order belief. However, when the prior belief was more weakly supported and the counterevidence was stronger, children changed their minds. These findings indicate that young children can revise their higher-order beliefs and, furthermore, do so depending on the strength of both the evidence and their prior beliefs.     

Rats’ responses to molar and local schedule constraints

Three experiments explored responses to molar and local schedule constraints. Thirsty rats pressed a lever for access to a water spout. In Experiment 1, response totals were unaffected by two local schedule characteristics—the variability of the instrumental requirement and the variability of the magnitude of contingent reward. Experiment 2 manipulated the correlation between the instrumental requirement and the magnitude of reward. This correlation did not affect the behavioral price ratio (presses per lick) at a molar level. At a local level, the positive correlation created a lower mean lick price than did the negative correlation. The rats licked more, and licked less efficiently, under the positive correlation than under the negative correlation. Experiment 3 compared two ways of manipulating the molar presses/lick ratio: The instrumental (contingent) series varied the instrumental (contingent) requirement, but held the other requirement constant. As the ratio increased, total leverpresses increased, and total licks decreased linearly; the two series did not differ significantly. At higher lick prices, the rats licked more efficiently and made more extra licks at the spout as it closed. The results help delimit the applicability of molar models of the organism’s response to schedule constraints.     

Anxiety, depression, and peer relationships during adolescence: Results from the Portuguese national health behaviour in school-aged children survey

Use data from the Portuguese HBSC (Health Behaviour in School-Aged Children) survey, which was conducted by one of the authors who is the national representative of the European Study HBSC, a World Health Organisation collaborative study (Currie, Hurrelmann, Setterbulte, Smith, & Todd, 2000; Matos, Simões, Carvalhosa, Reis & Canha 2000), to examine correlates of depression and anxiety in a large, representative sample of adolescents. The study had four aims: (1) to examine the relationship between feelings of anxiety and depression; (2) to examine the association of positive peer relationships, and anxiety and depression in school-age adolescents; (3) to examine the relationship between health, peer relationships, depression and anxiety; and finally, (4) to assess age and gender differences with regard to the above issues. Measures were constructed of depression, anxiety, peer relationships, and health. Consistent with previous studies, anxiety and depression were found to be significantly correlated. A MANOVA revealed that females and adolescents in grades 8 and 10 were more likely to report high anxiety and/or depressive symptoms. High anxiety and depression in adolescence was associated with poor peer relationships and poorer health. Implications of these results and directions for further research are discussed.     

The Home Environment Shapes Emotional Eating

Emotional overeating (EOE) is the tendency to eat more in response to negative emotions; its etiology in early life is unknown. We established the relative genetic and environmental influences on EOE in toddlerhood and early childhood. Data were from Gemini, a population‐based cohort of 2,402 British twins born in 2007. EOE was measured using the “emotional overeating” scale of the Child Eating Behavior Questionnaire (CEBQ) at 16 months and 5 years. A longitudinal quantitative genetic model established that genetic influences on EOE were minimal; on the other hand, shared environmental influences explained most of the variance. EOE was moderately stable from 16 months to 5 years and continuing environmental factors shared by twin pairs at both ages explained the longitudinal association.     

Creating the golden triangle of evidence-informed education technology with EDUCATE

EDUCATE is a London-based programme that supports the development of research-informed educational technology (EdTech), allowing entrepreneurs and start-ups to create their products and services, and simultaneously grow their companies in a more evidence-informed manner. The programme partners businesses with researchers who mentor, guide and support this research journey, a key aspect of which is the evaluation of the company’s EdTech product or service. However, conducting impact evaluations of technology in education is challenging, particularly for early stage technologies, as rapid cycles of innovation and change are part of their essence. Here, we present the pragmatic approach to evidence-informed education technology design and impact evaluation, as developed and adopted by the EDUCATE programme. The research process is shaped by the core principles of evidence-informed decision making detailed in the paper. The contributions of the paper are threefold. First, it defines and details an academia-industry-education collaboration model centred on a research training programme. Second, it presents emerging impact results of the programme. Third, it provides clear reflections on the challenges encountered during the implementation of the model in the EdTech ecosystem of London, which should be addressed if we are to move towards evidence-informed EdTech globally.     

The Distinctiveness of the EdD in Producing and Transforming Knowledge

The aim of this paper is to focus on the distinctiveness of the Professional doctorate in education (EdD) located in the development of higher education (HE) in England using Bourdieu’s theory of practice. It does this by building on a previous paper published in this journal, ‘The Distinctiveness of the EdD in the University Tradition’ (vol. 38, no. 3, 2006: 323–34). The paper uses Bourdieusian analysis to reveal the extent to which capital may have been misrecognized within HE. It then argues that the EdD may have developed within HE because it has the potential to recognize capital, previously misrecognized. Therefore, the EdD may be considered distinctive because it engages with issues surrounding social justice in terms of inclusion. Moreover, it may be argued that the EdD presents opportunities for educational practitioners to produce and transform knowledge, thus shaping the processes that structure what they can and cannot know and do.     

The degree to which students and teachers are involved in second-level school processes and participation in decision-making: an Irish Case Study

The Education Act (1998 Education Act. 1998. Dublin: Government Publications. [Google Scholar]) is a key policy document in Irish education, emphasising the rights, roles and responsibilities of key stakeholders, including parents, teachers and pupils in schools. Since 1998 the Department of Education and Skills (DES) has stressed the need to introduce an increased role for teachers and pupils in decision-making. It is therefore timely to explore the response of teachers and students to such a collaborative school environment in a rural second-level school of approximately 600 students. Transition year (TY) students (ages about 15–16) and their teachers were surveyed by questionnaire and interviewed. It finds that while the school is proactive in involving students and teachers in decision-making, a source of social, personal and professional empowerment, experienced teachers, and students in particular, want a more substantial voice. For example, most students want more say. They want class discussions or a vote, not just Student Council (SC) representation, on important and not just trivial issues. They want involvement before decisions are taken, with more feedback. Overall, participation is considered important by all stakeholders.     

Review of the Leaving Certificate biology examination papers (1999–2008) using Bloom’s taxonomy – an investigation of the cognitive demands of the examination

It is widely recognised that high-stakes assessment can significantly influence what is taught in the classroom. Many argue that high-stakes assessment results in a narrowed curriculum where students learn by rote rather than developing higher cognitive skills. This paper describes a study investigating the various cognitive objectives present from Bloom’s Taxonomy Educational Objectives on the Leaving Certificate biology examination. The study analysed examination papers from the past and current biology syllabuses. Analysis was also carried out to determine the marks being awarded to the different cognitive objectives. The findings show that the examination predominately includes questions that do not promote higher levels of thinking. The majority of the marks on the paper were allocated to the lower objectives of the taxonomy, suggesting students can rely on rote learning to succeed when undertaking the biology examination. This study strongly highlights how high-stake examinations have a narrow scope in terms of student achievement and shows how current biology examination procedures promote low-level learning. This low level of thinking promotes rote learning and regurgitation of facts, requiring little to no understanding of the topics. To prepare students for the working world, there needs to be a shift from only terminal exams to a mixed approach.     

Impact of stimulus format and reward value on quantity discrimination in capuchin and squirrel monkeys

Quantity discrimination abilities are seen in a diverse range of species with similarities in performance patterns, suggesting common underlying cognitive mechanisms. However, methodological factors that impact performance make it difficult to draw broad phylogenetic comparisons of numerical cognition across studies. For example, some Old World monkeys selected a higher quantity stimulus more frequently when choosing between inedible (pebbles) than edible (food) stimuli. In Experiment 1 we presented brown capuchin (Cebus [Sapajus] paella) and squirrel monkeys (Saimiri sciureus) with the same two-choice quantity discrimination task in three different stimulus conditions: edible, inedible, and edible replaced (in which choice stimuli were food items that stood in for the same quantity of food items that were given as a reward). Unlike Old World monkeys, capuchins selected the higher quantity stimulus more in the edible condition and squirrel monkeys showed generally poor performance across all stimulus types. Performance patterns suggested that differences in subjective reward value might motivate differences in choice behavior between and within species. In Experiment 2 we manipulated the subjective reinforcement value of the reward by varying reward type and delay to reinforcement and found that delay to reinforcement had no impact on choice behavior, while increasing the value of the reward significantly improved performance by both species. The results of this study indicate that species presented with identical tasks may respond differently to methodological factors such as stimulus and reward types, resulting in significant differences in choice behavior that may lead to spurious suggestions of species differences in cognitive abilities.     

Use of national parks for outdoor environmental education: An Australian case study

The need for environmental education through outdoor education experiences is becoming increasingly evident in outdoor education theory and practice. In Australia, this environmental focus is reflected in recent outdoor education curriculum documents, particularly in the Victorian Certificate of Education (VCE). For many outdoor education teachers who do not have expertise in environmental education, this curriculum development presents a challenge. Outdoor education teachers frequently use National Parks to help them address this challenge.

The study examined the educational objectives and roles of teachers and park staff involved in environmental education through outdoor education in National Parks in Victoria, Australia. This paper discusses findings related to the teachers' educational objectives and roles while those of the park staff are examined in a separate paper. The findings indicate that the teachers often lack the environmental knowledge and skills needed to teach some aspects of the curriculum thus making the role of the park ranger or education officer particularly significant in educating teachers as well as students. Issues are raised about the training of outdoor education teachers and of park rangers to meet the environmental education needs of outdoor education students. Questions are also raised about the appropriateness of using National Parks for outdoor education purposes.
