Recovery of the rabbit’s conditioned nictitating membrane response without direct reinforcement after extinction

Three experiments demonstrated that, following the extinction of an established conditioned stimulus (CSA—e.g., tone), the pairing of a novel, cross-modal stimulus (CSB—e.g., light) with the unconditioned stimulus (US) results in strong recovery of responding to the extinguished CSA. Experiment 1 demonstrated that the recovery of responding to CSA is not the result of US reinstatement but is attributable to pairings of CSB with the US. Experiment 2 demonstrated that the recovery of responding is specific to CSA and is not the result of cross-modal generalization. Experiment 3 revealed that a large number of CSB-US pairings in Stage 1 significantly reduced the amount of recovery to CSA during subsequent CSB-US trials. Experiment 3 also provided unexpected evidence of cross-modal secondary extinction. The extinction and subsequent recovery of responding seen in the present experiments is discussed with respect to possible contributions from contextual associations, CS processing, US processing, conditioned response expression, and layered excitatory associations.     

Single-sex schooling and subject choice: Pattern of enrolment at Monash University

Using data collected from incoming students at Monash University from 1972 to 1990, this study assesses the impact of single-sex versus coeducational schooling on the faculty choice of both female and male students. A clear pattern emerges of students from co-educational schools being over-represented in Science and Engineering and under-represented in Law and Medicine and, in recent years, in Economics and Politics. This is true for both females and males. However, further analysis establishes that this is more likely to be caused by socio-economic factors than by the gender composition of the school attended, since most students from co-educational schools come from the government sector and most students from single-sex schools from the independent sector.     

Embodied encounters with more-than-human nature in health and physical education

ABSTRACT

Despite the importance of interactions with natural environments for personal and social well-being, there is only limited evidence of the relationship between the environment and health as an idea or area of study in school education in Australia. Logically, the place for such a study, at least in Australia, would be within the Health & Physical Education (HPE) key learning area. However, in HPE, alternative ways of considering health beyond the dominant ‘healthism’ discourses which privilege physical activity, fitness, food and nutrition struggle for any kind of existence. Gruenewald (2004. A Foucauldian analysis of environmental education: Toward the socioecological challenge of the earth charter. Curriculum Inquiry, 34(1), 71–107) suggests looking to the margins of a field to see what knowledge is silenced or subjugated in order to open up new conditions of possibility. This challenged us to look beyond taken for granted ways of thinking about health to identify other resources, perhaps unrecognised as yet, that teachers might draw on to constitute their knowledge of health. To do this, we look to interview data collected when teachers were asked to talk about their personal experiences of the relationship between the environment and health. The analysis of the interviews demonstrated how the teachers conceptualised the relationship between the environment and health by drawing on embodied experiences and affective encounters with more-than-human nature. By theorising these encounters through a post-human, new-materialist lens, we demonstrate how their corporeal knowledge, developed through embodied experiences, has the potential to assist teachers in formulating less institutionalised health understandings. We argue that these encounters with more-than-human nature can serve as alternatives to those dominant healthism discourses that invoke problematic risk, fear and crisis responses.     

Pressures and influences on school leaders navigating policy development during the COVID-19 pandemic

The pressures and influences experienced by school leaders as school policymakers, during the first responses to COVID-19 pandemic, made their task of interpreting, translating and implementing school guidance both difficult and stressful. During COVID-19 pandemic, school leaders faced challenges to prioritise and balance ever-changing government policy advice with the limitations of school buildings, the welfare of students and staff, and the needs of communities, a task made complicated by the methods of communication used by government. By surveying and interviewing headteachers, senior leaders and governors, this article identifies the reactions and responses of school leaders who construct and enact policy in the context of COVID-19 pandemic. The article addresses the nature of, and factors affecting, pressures school leaders feel in authoring and implementing policy. These pressures are non-trivial and increase tension in already highly stressful work. The report draws on data collected from a randomised, stratified sample of primary and secondary school leaders from across England in early June 2020, during the time of national lockdown and remote learning. Findings suggest quality, quantity and frequency of top-down communication contributed to school leader stress, while horizontal communication and collaboration between school leaders and across school communities supported leaders during rapid change. We recommend that government and the Department of Education strengthen and streamline stressful communication systems while building cooperative communities, mitigating against the challenges identified by school leaders during the COVID-19 pandemic.     

Providing Access to Engagement in Learning: The Potential of Universal Design for Learning in Museum Design

Following passage of the Americans with Disabilities Act of 1990 (ADA), many museums improved the accessibility of their facilities. Even so, individuals with disabilities still lag behind in participation and engagement in museum experiences. Universal Design for Learning (UDL) provides an alternate model for the design of museum programs and exhibit spaces, one that is more aligned to progressive concepts of disability, providing not only physical access but also access to engagement in learning. In this article we argue that UDL has the potential to substantially improve the design of informal learning environments. Through two illustrative examples, we describe how the UDL design guidelines can be used to improve the probability that engagement will occur as individuals interact with exhibits, programs, and people in museums.     

Differences in trunk and upper extremity kinematics and segmental velocities during the offside forehand polo swing between male and female athletes

ABSTRACT

Although polo is a well-known equestrian sport, it is fundamentally misunderstood. The purpose of this study was to examine trunk and upper extremity kinematics and segmental velocities during the offside forehand polo swing between male and female athletes. Ten female and 17 male professional polo athletes volunteered. An electromagnetic tracking system collected kinematic data at 100 Hz while participants performed three offside forehand polo swings from a stationary wooden horse. One-way ANOVAs revealed statistically significant differences (p<0.05) in all kinematic variables and segmental velocities. Specifically, males exhibited a greater mean difference (MD=23°) of trunk flexion at take away (TA) and top of backswing (TOB)(MD=29°) trunk lateral flexion at ball contact (BC)(MD=23°), trunk rotation at TA(MD=97°) and TOB(MD=118°), shoulder abduction at TOB(MD=64°), and shoulder elevation at TOB(MD=13°) and BC(MD=40°). Females displayed greater trunk rotation at BC(MD=91°), shoulder elevation at TA(MD=19°), and elbow flexion at TA(MD=90°). Additionally, females generated greater segmental velocities early in the swing, while the males generated velocity later. The movement patterns observed amongst the males suggest energy is being transferred more efficiently along the kinetic chain, thus more efficient swing mechanics, but further investigation into the role of the trunk and lumbopelvic-hip complex in reference to the polo swing is warranted.     

Enrolment trends in school science education in Australia

Investigations were carried out to find the amount of science portrayed by terrestrial television in the UK and the public comprehension of that science as shown on television. UK terrestrial programming was derived from the Radio Times . Advertisement information was derived from UK terrestrial commercial television commercials. Public opinions were solicited by a survey of 200 members of the public ( n = 196). Science-based programming formed 5.36% of all terrestrial broadcasting time, with people watching an average of 1.75 science programmes per week (approx. 0.2% of programmes possible). 65% of all television advertisements were found to be science-based, although only 26% of advertisement categories were recognized as being science-based by the public. If interest in science is reflected in the amount of science programmes watched then the public are not interested in science. The lack of comprehension of the scientific basis of many advertisements is indicative of the lack of relevance of science education to people in modern society.     

Poverty, Relationship Conflict, and the Regulation of Cortisol in Small and Large Group Contexts at Child Care

The purpose of this research is to explore the dynamics of cortisol regulation in the context of center-based child care by examining the impact of social context (large classroom vs. small group) and relationship quality with caregivers (conflict with mothers and teachers). We extend the research on children's physiologic stress system functioning in center-based child care by focusing on morning cortisol levels among young children living in poverty. While in high-quality center-based child care, children's cortisol levels decreased over the course of the morning—a result that contrasts with findings in previous research with middle-class children, for whom cortisol typically increased over the course of the day while attending center-based child care. Cortisol levels were further reduced when children were moved from a large classroom environment to a small group context. Relationship conflict with mothers and teachers moderated these effects. Children who had high conflict with their mother exhibited cortisol levels that remained higher (decreased less) over the course of the morning, and children who had high conflict with their teacher exhibited cortisol levels that remained higher (decreased less) in response to the small group context. These results indicate that high-quality child care has the potential to support reduced stress among children living in poverty, at least as indicated by adrenocortical activity.     

Can business schools increase student employability by embedding action learning into undergraduate management education? An account of practice

ABSTRACT

Management education is at a pivotal crossroads. In an increasingly globalized world, where change is the only constant, business school graduates leaving university are faced with ever intensifying competition and complexity. Universities have responded by increasing their emphasis on teaching ‘employability skills’ to graduates. However, undergraduate management curricula still often focus on Programmed Knowledge, which does not adequately prepare graduates for the labour market to which they will inevitably graduate. A Future Search exercise was implemented to help conceptualize new visions of the future of management education, considering the question ‘to what extent does management education impact on management practice?’ This paper asserts that integrating Questioning Insight and a scholarly practice approach into management education will better equip graduates for the world of work. The authors utilize Kotter’s 8-stage model of change to outline a pathway for change and action for business schools to adapt a scholarly practice approach to education into their curricula.     

An exploration of anatomists’ views toward the use of body painting in anatomical and medical education: An international study

Previous research has explored the experiences of medical students using body painting as a learning tool. However, to date, faculty experiences and views have not been explored. This international qualitative study utilized a grounded theory approach with data collection through interviews with academics and clinicians who utilized body painting as part of their anatomical teaching. Twenty‐six anatomists participated in the study from 14 centers worldwide. Three themes emerged from the data: (1) the efficacy of body painting, (2) the promotion of knowledge retention and recall, (3) considerations and practicalities regarding the use of body painting as a teaching tool. Subthemes show that body painting is used as an adjunct to the curriculum for teaching surface anatomy and peer examination. Benefits included diffusing the formal curricula, high student engagement and learning for future clinical practice. Body painting was advocated for promoting knowledge retention and recall, particularly learning through the process of cognitive load due to combining the use of color and kinesthetic learning with anatomical theory. Critical discussions surfaced on the topic of undressing in the classroom due to cultural and personal considerations possibly leading to unequal involvement and different learning experiences. Overall results support previous research showing that anatomists appreciate body painting as an effective, enjoyable, engaging and cost efficient adjunct to the multimodal anatomy curriculum. The role of cognitive load theory in learning anatomy through body painting emerged from the data as a possible theoretical framework supporting learning benefits from body painting and is suggested for further investigation.
