Verbal Short-Term Memory Span in Speech-Disordered Children: Implications for Articulatory Coding in Short-Term Memory     

Adrian Raine  Charles Hulme  Helen Chadderton  Pauline Bailey 《Child development》1991,62(2):415-423

One influential explanation of the development of verbal short-term memory in children argues that short-term memory capacity is a direct function of speech rate. This theory predicts that children with pathologically slow speech will show reduced verbal short-term memory capacity and will show less evidence of speech-base coding on verbal memory tasks. To test this prediction, verbal short-term memory span was assessed using a task that did not require a verbal response in 37 speech-disordered children and 37 age- and sex-matched controls (age range 4-15 years). The speech-disordered group had a significantly lower short-term memory capacity, a smaller word length effect, and reduced speech-motor activity during rehearsal periods. Covariance analyses revealed that these differences were not a function of general intellectual or motor speed differences between the groups, and that speech rate as a covariate abolished group differences in short-term memory. These results suggest that speech rate may be a causal determinant of verbal short-term memory capacity.  相似文献   

Determinants of Attraction,Retention and Completion for Aboriginal and Torres Strait Islander Higher Degree Research Students: A Systematic Review to Inform Future Research Directions     

Hutchings  Kate  Bainbridge  Roxanne  Bodle  Kerry  Miller  Adrian 《Research in higher education》2019,60(2):245-272

Expanding the Aboriginal and Torres Strait Islander Australian (hereafter respectfully Indigenous) talent pool to undertake valuable roles in business, health, education, academia, government, policy development and community development is critical for addressing current disparities between Indigenous and other Australians. Parity of access and engagement with education plays a key role in facilitating participation in these roles but has not yet been attained. This article provides an initial systematic review of literature on the state of the evidence regarding access/attraction, retention and completions for Indigenous Higher Degree Research (HDR) students. This article identifies the quantity (number examined), nature (e.g. focus of study), quality (peer reviewed and evidence of methodological rigour) and characteristics (e.g. publication type, authorship) of the limited publications. Using specific search strings (words or phrases of relevance to the topic), a systematic review methodology was employed to search nine databases and grey (non-peer reviewed) literature from 1995 to 2015. The resultant 12 publications were mined with quality assessed and a predetermined framework used to extract and synthesise the characteristics from individual publications. This research contributes to existing literature about Indigenous Peoples in HDR programs internationally in identifying significant cultural and institutional barriers and highlighting institutional enablers which can contribute to attraction, retention and completion. Building on the prior limited research reported in the review, the article highlights the need for further research and provides an initial agenda of directions for universities and government to redress the disparity in entry and completion of Indigenous Peoples in HDR programs.

Oral History and Teachers’ Professional Practice: a wartime turning point?     

Philip Gardner  Peter Cunningham 《Cambridge Journal of Education》1997,27(3):331-342

This exploratory article has a two‐fold aim. In the first place, it seeks to investigate changing patterns of teacher‐pupil relationships in the twentieth century through the lens of the professional lives and pedagogical practices of classroom teachers themselves. Such an investigation is engaged through the application of oral history methods. An unexpected result of a succession of oral history interviews has been the identification, by former teachers themselves, of wartime evacuation as a significant turning point in the development of teacher‐pupil relationships. The second aim of the article is to relate the findings of oral history interviews to those which emerge from documentary and secondary sources. In this way, the particular strengths of oral history methods for the investigation of past pedagogical practice are assessed.  相似文献   

Apprehending Mathematical Structure: A Case Study of Coming to Understand a Commutative Ring     

Adrian Simpson  Nada Stehlíková 《Educational Studies in Mathematics》2006,61(3):347-371

Abstract algebra courses tend to take one of two pedagogical routes: from examples of mathematics structures through definitions to general theorems, or directly from definitions to general theorems. The former route seems to be based on the implicit pedagogical intention that students will use their understanding of particular examples of an algebraic structure to get a sense of those properties which form the basis of the fundamental definitions. We will explain the transition from examples to abstract algebra as a series of shifts of attention and in this paper we will use a case study to examine the initial shift, which we will call apprehending a structure, and examine how one student came to apprehend the structure of the commutative ring Z₉₉.  相似文献   

The erasure of reinstated fear     

Robert A. Rescorla  Christopher L. Cunningham 《Learning & behavior》1977,5(4):386-394

Three experiments investigated the reinstatement of fear to a previously conditioned and extinguished CS as a result of separate presentation of the original US. That reinstatement was found to be sharply attenuated by nonreinforcement of a second fear elicitor between presentations of the US and testing of the CS. This “erasure” of reinstatement depended upon the fear-eliciting power of the intervening stimulus and, under some circumstances, was essentially complete. Moreover, erasure reduced not only the response to the CS but also the extinction it underwent as a result of subsequent nonreinforcement. It is argued that neither the conditioning of background stimuli nor stimulus generalization among explicit CSs provides an adequate account of these reinstatement and erasure results. Rather, they are interpreted in terms of the construction and destruction of a nonassociative representation of the US during conditioning, extinction, reinstatement, and erasure. In that context, some inferences can be made about the rules governing these nonassociative changes and the ways in which they interact with modifications in associations.  相似文献   

Conditional inference and advanced mathematical study     

Matthew Inglis  Adrian Simpson 《Educational Studies in Mathematics》2008,67(3):187-204

Many mathematicians and curriculum bodies have argued in favour of the theory of formal discipline: that studying advanced mathematics develops one’s ability to reason logically. In this paper we explore this view by directly comparing the inferences drawn from abstract conditional statements by advanced mathematics students and well-educated arts students. The mathematics students in the study were found to endorse fewer invalid conditional inferences than the arts students, but they did not endorse significantly more valid inferences. We establish that both groups tended to endorse more inferences which led to negated conclusions than inferences which led to affirmative conclusions (a phenomenon known as the negative conclusion effect). In contrast, however, we demonstrate that, unlike the arts students, the mathematics students did not exhibit the affirmative premise effect: the tendency to endorse more inferences with affirmative premises than with negated premises. We speculate that this latter result may be due to an increased ability for successful mathematics students to be able to ‘see through’ opaque representations. Overall, our data are consistent with a version of the formal discipline view. However, there are important caveats; in particular, we demonstrate that there is no simplistic relationship between the study of advanced mathematics and conditional inference behaviour.

Progress report on the development of child abuse prevention, identification, and treatment systems in Eastern Europe

PROBLEM: After the Soviet Union dissolved in 1989, it became apparent that there was little recognition of the problems of child abuse and neglect, professionally, legally, or societally. There were no effective systems or laws in place to deal with these problems. METHOD: Beginning in 1995 the Children's Mental Health Alliance, in conjunction with the Open Society Institute began conducting trainings in Eastern Europe [Journal of the American Academy of Child Adolescent Psychiatry 39 (2000) 660]. Originally 18 countries from the Baltics to the Balkans participated. A program was elaborated which would proceed in several stages: (1) training mental health professionals to deal with child abuse and neglect (CAN); (2) teaching multidisciplinary team work and fostering the development of multidisciplinary NGOs focused on CAN; (3) promoting the self-sufficiency of these NGO's which would then facilitate social and legal reform and increase public awareness of the problem. Specific methods included multi-national trainings, assignment of mentors to the developing teams who maintained weekly contact with the teams and made yearly site visits to their countries, and overseeing project grants from OSI. RESULTS: NGO's had been established and registered in 11 countries, many establishing a network of programs within their countries. By 2000, over 3800 mental health professional had been trained, either directly by the program or by the trainees of the program. By the end of 2000, over 17,000 other professionals (lawyers, police, judges, educators, other physicians, etc.) had been trained by the network. CONCLUSION: While more work needs to be in this region, the teams in 11 countries have made solid starts.  相似文献   

Exploring the relationship between homework task difficulty,student engagement and performance     

Raymond Lynch  Adrian Hurley  Olivia Cumiskey  Brian Nolan  Bridgeen McGlynn 《Irish Educational Studies》2019,38(1):89-103

This article considers the relationship between differential homework task difficulty, student engagement and performance across four Irish post-primary school sites. A total of 236 participants completed all elements of this study. All participants were junior cycle students, aged between 12 and 16 years. The study employed a standardised test–retest approach, with a one week interval between tests. Between testing, participants were randomly subdivided into three cohorts. Each cohort received homework questions of different difficulty levels to complete for one week. The results of this study found that Cohort A, who received the least difficult homework tasks, completed the most non-compulsory questions. Although Cohort A demonstrated higher levels of engagement, no statistically significant difference was found in the change in performance scores of the three cohorts. The results highlight the negative impact of increased task difficulty on student engagement with independent homework tasks. The findings suggest that in order to support student engagement it is important that teachers afford ample opportunity for student success when designing self-directed tasks such as homework.  相似文献
