Discrimination of the number of sequential events by rats

Ten rats were trained to press a right lever following two successive sounds and to press a left lever following four successive sounds. Three sound sequences were used in initial discrimination training, such that reliable classification could not be based on the duration of each sound, the interval between sounds, or the total duration of the sound sequence. Classification of seven novel sound sequences suggested that the animals were either using number or the sum of sound durations in a sequence as the relevant cue. When this total sound duration was put in conflict with number, rats classified by number. The conclusion was that rats can discriminate number, even when temporal cues are controlled.     

Angry Anglos and aspirational Asians: everyday multiculturalism in the selective school system in Sydney

ABSTRACT

‘Asian whiz kids’ perfect test scores.’ ‘Selective schools and tiger parents.’ These types of headlines highlight the increased visibility of academically successful students from Asian migrant backgrounds, in Australia and other Western countries. They also point to anxiety about the perceived aggressive ‘tiger’ parenting often associated with Asian academic success. This paper focuses on the forms of everyday multiculturalism found in and around high-performing selective schools and classes in Sydney, Australia, almost all of which are dominated by Asian-Australian students. Drawing on interviews with parents and students from Anglo- and Asian-Australian backgrounds, it documents the different positionalities adopted by participants within these culturally diverse settings, including anger, aspiration and cosmopolitanism. This potentially volatile combination of approaches to diversity reveals some of the social consequences of neoliberal migration and education policies.     

Negotiating colonial structures: challenging the views of Pakeha student teachers

This paper describes an attempt to address, through pre‐service teacher education, the complex interaction of the ideologies carried by schooling, the denial of the rights of Maori as promised by the Treaty of Waitangi and the underachievement of Maori children in New Zealand schools. It is set in the context of an action research project that sought to reveal student teachers' responses to this component of their degree programme. The authors describe how, as teacher educators, their teaching evolved in response to the research findings through three distinct phases.     

Mind the gap: accountability,observation and special education

There is an absence of observation-based tools designed to evaluate teaching in special education classrooms. Evaluations derived from classroom observations are integral to the accountability process, adding value to understanding teaching and learning by providing a lens into the classroom that test scores cannot capture. The present paper systematically examined existing classroom observation tools, identifying constructs measured and noting elements unique to special education classrooms. Results demonstrate that most extant tools tap into three primary categories of teacher behaviours, but overlook the role paraprofessionals play as well as teacher professional behaviours. Taken together, results reflect the need for a tool designed specifically for special education classrooms. Limitations and implications for practice and policy are discussed.     

Learning at the nanoscale: The impact of students' use of remote microscopy on concepts of viruses,scale, and microscopy

The rapid pace of development is bringing advanced technologies to the World Wide Web (WWW), and, as a result, schools have access to new tools for science investigations. In this exploratory study, we investigated how an educational experience organized around students' use of a WWW‐controllable atomic force microscope (AFM) influenced students' understandings of viruses. The context for the study was a weeklong unit on viruses for two high school biology classes which incorporated student use of the WWW controllable AFM. We also investigated how the haptic (involving kinesthetics and touch) experiences afforded by this tool might influence students' knowledge of viruses, microscopy, and nanometer scale. Fifty students from two high school biology classes participated in a series of instructional activities and pre‐ and postassessments (knowledge test, opinion questionnaire, and interviews). Results showed that students' understandings of microscale, virus morphology, and dimensionality changed as a result of the experiences. Students' conceptions moved from a two‐dimensional textbook‐like image of a virus to a three‐dimensional image of an adenovirus. The results of this preliminary study suggest that the use of the technology as a tool for learning about morphology of materials too small to see may be beneficial. © 2003 Wiley Periodicals, Inc.

Self-efficacy as a predictor of clinical skills among speech pathology students

Bandura's self-efficacy theory was used a model for examining levels of confidence and clinical skills among undergraduate speech pathology students. Forty-four second-year students rated their confidence in their ability to perform a number of clinical tasks at the beginning and at the end of the academic year, which was their first clinic experience. These efficacy expectations were compared with clinical supervisors' assessments of the students' performance on the same tasks. An attempt was also made to assign students to pairs and small groups for training on the basis of their initial efficacy expectations Efficacy strength (but not level) increased significantly over the year, and efficacy level (but not strength) was moderately and significantly related to clinical supervisors' ratings of clinic performance. Practical problems arose with the grouping, but the results suggested that there may be some possible benefits from assigning students to pairs on the basis of their self-efficacy. These results show self-efficacy to be only moderately well related to clinic performance, but it is suggested that relatively high baselines may have attenuated the strength of the obtained relationship. The role of self-efficacy in clinical skills training warrants further investigation.     

Racial Identity and Psychological Symptoms Among African Americans Attending a Historically Black University

Previous research found racial identity predictive of psychological distress among African American students at predominantly White colleges. This study examined these relationships among 154 African American undergraduates attending a historically Black university. Racial identity was independent of psychological distress, suggesting that African American students' racial identity predicts psychological distress only in settings in which they are the minority.     

The future of higher education in Ireland: a postcolonial perspective

The transformation that Irish higher education (HE) has undergone since the mid-2000s has been particularly rapid and unidirectional. Following the Global Financial Crisis, the Irish Government sought to take control of tertiary education in an attempt to shield the country from future economic shocks. This paper succinctly discusses the circumstances leading to the current policy position and what these changes have meant for Irish HE. A postulation that neoliberalism will inevitably deepen further within Irish HE will be explored through the lens of Postcolonial theory. In conclusion, I will show that the application of this theoretical stance may succeed in buffering many of the effects of neoliberalism to ensure ample space in HE for all subject areas and disciplines.
