Extinction of enhanced latent inhibition     

Phil Reed  Pany Petrochilos  Natasha Upal  Martin Baum 《Learning & behavior》1997,25(3):283-290

Hungry rats were used in a classical conditioning procedure in which visual stimuli were paired with food. Conditions in which nonreinforced exposure to a nontarget stimulus was followed by exposure to a simultaneous compound nontarget/target stimulus (a blocking procedure) resulted in enhanced latent inhibition to the target relative to exposure to the nontarget, followed by exposure to the target stimulus alone. A third phase of nonreinforced exposure training, in which the target was exposed alone following the compound, reduced levels of latent inhibition relative to results obtained with the blocking procedure. Experiments also suggested that this was not the result of restoration of associability by the omission of an expected presentation of the nontarget stimulus in the final preexposure phase. These results suggest that enhanced latent inhibition is due to summation of a direct-target-no-event association and a second-order association of these elements via target-nontarget and nontarget-no-event association. Exposure to the target after compound exposure extinguished the target-nontarget association and reduced the sources of no-event learning for the target.  相似文献   

‘I Am the Hate that Dare Not Speak its Name’: Dealing with homophobia in secondary schools     

Natasha Adams  Tamsin Cox  Laura Dunstan 《Educational Psychology in Practice》2004,20(3):259-269

This paper describes the outcomes of a small‐scale project involving 19 secondary schools. The project investigated how effectively issues of homophobic bullying and sexualities were addressed through secondary schools' formal policies and areas of the curriculum. Outcomes indicate that sexual orientation was mentioned in two‐thirds of Equal Opportunities policies but was not mentioned specifically in any Anti‐Bullying policies. Staff highlighted the need for training in issues surrounding sexualities, homophobic bullying and clarification of Section 28. Implications for the work of educational psychologists are discussed, including raising awareness and clarifying issues in schools as well as informing whole school development work.  相似文献   

Unpacking the career aspirations of Australian school students: towards an evidence base for university equity initiatives in schools     

Jennifer Gore  Kathryn Holmes  Max Smith  Leanne Fray  Patrick McElduff  Natasha Weaver 《高等教育研究与发展》2017,36(7):1383-1400

Demand for higher education in Australia has doubled since 1989, increasing the number of students from diverse social, economic and academic backgrounds. Equity targets have seen a proliferation of programs and interventions aimed at encouraging school students, particularly those from low socio-economic status backgrounds, to participate in higher education. However, little is known about the specific occupational interests of school students upon which targeted strategies might effectively be designed and implemented. This paper examines school students’ aspirations for specific careers that require a university education, in relation to student background and school-related variables. The analysis draws from a study of 6492 students from Years 3 to 12 in 64 New South Wales public schools. We found a complex array of factors relating to interest in different careers. Year level at school, gender and prior achievement were stronger predictors across many careers than factors such as SES, Indigenous status and school location. We argue that rather than taking a one-size-fits-all approach to encouraging participation in higher education, outreach activities should be targeted to take account of student diversity and inequalities that foster differing aspirations.  相似文献   

Dimensions of student success: a framework for defining and evaluating support for learning in higher education

ABSTRACT

The capabilities students need for success during and beyond higher education extend far beyond specific discipline skills to include the development of productive mindsets, the management of life circumstances and the way they relate to others and identify with their profession. The provision of support for these capabilities at university can be both diverse in scope and diffuse in delivery. Consequently, the development of streamlined and integrated evaluation strategies to measure the extent to which these capabilities are being successfully delivered can be challenging. This paper describes how one Australian university used a collaborative process to design an evaluation framework for student learning services. The framework, a first for this university, represents the breadth of student support, including a typology of support for learning: connectedness, mindsets, self-management, professional identity and academic capabilities. These terms, coined as dimensions, form the scaffold of university-wide delivery of support for learning initiatives.  相似文献   

What do medical students learn from dissection?          下载免费PDF全文

Natasha A.M.S. Flack  Helen D. Nicholson 《Anatomical sciences education》2018,11(4):325-335

Dissection has long been the accepted method for teaching anatomy to medical students. More recently, some educators have suggested that easier, cheaper, alternative methods are just as effective. But what do the students think? This paper aimed to identify what undergraduate medical students learn, how they cope, and what effects participating in dissection has on them as individuals. A cohort of 267 second year medical students at Otago Medical School were invited to complete three online surveys; before their first dissection laboratory class, after their first musculoskeletal system dissection and following the last semester of studying anatomy. Open‐ended questions showcasing the attitudes, beliefs, and opinions on what dissection had taught the medical students over years two and three were analyzed. A general inductive approach was used and common emergent themes were identified. In total, 194 students completed the second, and 108 students completed the third questionnaire. Students commonly conveyed dissection as an appropriate and valuable educational tool, useful for teaching and learning anatomical knowledge and relationships, appreciating the body in three‐dimension, teamwork, and how to cope with death/dead bodies. The noted effects of personal growth while participating in dissection were highly varied, but in general, impacted positively on the majority of students. This study shows that at Otago Medical School the students also believe that dissection is not only a useful tool to learn anatomy but also that it fosters teamwork, assists professional development and helps them come to terms with death and dying.

Dyadic Curve-of-Factors Model: An Introduction and Illustration of a Model for Longitudinal Nonexchangeable Dyadic Data     

Tiffany A. Whittaker  S. Natasha Beretvas  Toni Falbo 《Structural equation modeling》2013,20(2):303-317

The analysis of longitudinal data collected from nonexchangeable dyads presents a challenge for applied researchers for various reasons. This article introduces the dyadic curve-of-factors model (D–COFM), which extends the curve-of-factors model (COFM) proposed by McArdle (1988) for use with nonexchangeable dyadic data. The D–COFM overcomes problems with modeling composite scores across time and instead permits examination of the growth in latent constructs over time. The D–COFM also appropriately models the interdependency among nonexchangeable dyads. Different parameterizations of the D–COFM are illustrated and discussed using a real data set to aid applied researchers when analyzing dyadic longitudinal data.  相似文献   

Learning in and for cross‐school working     

Harry Daniels  Jane Leadbetter  Allan Soares  Natasha MacNab 《牛津教育评论》2013,39(2):125-142

In this study we report some of the outcomes of a study of professional learning that took place in cross school partnerships as they worked towards promoting creativity in schools. The methodology developed by Engeström and his colleagues at The Centre for Developmental Work Research in Helsinki was adopted. This form of intervention involves the preparation and facilitation of workshops in which the underlying structural contradictions that are in play in emergent activities are highlighted and articulated in such a way that participants may engage with what may otherwise remain hidden and unexamined tensions. This approach is based on the writings of the early 20th‐century Russian school of social scientists—Vygotsky, Luria and Leontiev. A principal claim is that the development of creativity requires tools and contexts for such innovatory forms of practice. This study suggests that this claim is a partial representation of the development of creative activity.  相似文献   

More than experiential learning or volunteering: a case study of community service learning within the Australian context     

Elizabeth Anne Parker  Natasha Myers  Helen Christine Higgins  Thorun Oddsson  Meegan Price  Trish Gould 《高等教育研究与发展》2009,28(6):585-596

Community service learning is the integration of experiential learning and community service into coursework such that community needs are met and students gain both professional skills and a sense of civic responsibility. A critical component is student reflection. This paper provides an example of the application of community service learning within an undergraduate health unit at the Queensland University of Technology. Based on survey data from 36 program participants, it demonstrates the impact of CSL on student outcomes. Results show that students benefited by developing autonomy through real world experiences, through increased self‐assurance and achievement of personal growth, through gaining new insights into the operations of community service organisations and through moving towards becoming responsible citizens. Students expect their CSL experience to have long‐lasting impact on their lives, with two‐thirds of participants noting that they would like to continue volunteering as part of their future development.  相似文献   

“There’s no such thing as Asian”: A membership categorization analysis of cross-cultural adaptation in an Asian American business community     

Natasha Shrikant 《Journal of International and Intercultural Communication》2018,11(4):286-303

This paper examines the relationship between communication and cross-cultural adaptation through conducting a membership categorization analysis of interactions among members of an Asian American Chamber of Commerce (AACC). Analysis of audio-and-video-recorded data gathered during ethnographic fieldwork illustrates how immigrant AACC members adapt to US notions of race through adopting the “Asian” racial category yet define “Asian” in creative ways that meet institutional goals. AACC members also resist US essentialist racial ideology through identifying with ethnic categories that help members meet situated institutional goals. Overall, this paper highlights how members routinely switch among racial, ethnic, and professional identity categories when navigating structural constraints of racial ideology during cross-cultural adaptation in institutional contexts.  相似文献   

Career Success in Training & Development: Is It What You Know or Who You Know?     

Natasha O'Connor  Kathleen Iverson  Deborah Colky 《Performance Improvement Quarterly》2003,16(3):5-16

A model illustrating the relationship between mentoring and job competency was developed and tested in a sample of 82 members of a local chapter of a national association for training and development professionals. Human capital was conceptualized in terms of job competency attainment and social capital in terms of mentoring and protégé relationships. A series of hierarchical regression analyses were run to test the path model. Although a positive relationship was found between acting as a protégé and job satisfaction, acting as a mentor had a negative relationship with income. The results showed a strong relationship between career competence and income, promotion, job satisfaction and career choice satisfaction. For training and development professionals, job competency is the key factor in their career success.  相似文献
