The development of case studies as a method within a longitudinal study of special educational needs provision in the Republic of Ireland

When developing case studies within a longitudinal study of special educational needs provision within the Republic of Ireland, the authors were conscious of the critiques of the use of this approach within educational research. The difficulties associated with generalisation, challenges of ensuring trustworthiness and the possibilities of researcher bias have been identified as limiting factors in the presentation of case study data. In order to confront these limitations, the researchers developed a framework for case study development that aimed to provide a secure database and trustworthy interpretation in order to make assertions in relation to special educational needs provision. This paper describes this process and suggests that the need to develop safeguards in order to present case studies that have high degree of credibility is essential when using this approach. Furthermore, the transparency of research methods, a significant omission in many reports of research, is necessary in order to demonstrate the trustworthiness of data.     

Mathematical situations of play and exploration

The mathematical situations of play and exploration introduced here have been developed as an empirical research instrument for the longitudinal study “erStMaL” (early Steps in Mathematics Learning). They are designed as situations that allow children and a guiding adult to construct situation-related knowledge in common dialogue processes and in mutual conditions. In addition, the situations focus on the activity of the persons involved, as well as the meaning of artefacts as objects of different cultural worlds. Besides relevant theoretical aspects for the development of the mathematical situations of play and exploration, exemplary analyses are introduced to clarify the conceptual aims.     

Nonword repetition with spectrally reduced speech: some developmental and clinical findings from pediatric cochlear implantation

Nonword repetition skills were examined in 24 pediatric cochlear implant (CI) users and 18 normal-hearing (NH) adult listeners listening through a CI simulator. Two separate groups of NH adult listeners assigned accuracy ratings to the nonword responses of the pediatric CI users and the NH adult speakers. Overall, the nonword repetitions of children using CIs were rated as more accurate than the nonword repetitions of the adults. The nonword repetition accuracy ratings from both groups of subjects were correlated with open- and closed-set word recognition scores and forward digit spans. Only the perceptual accuracy scores from pediatric CI users were correlated with measures of speech production accuracy. These results suggest that although the pediatric CI users had more experience and success in perceiving speech under degraded auditory conditions, developmental differences in their memory skills prevent them from performing as well on working memory tasks as mature listeners.     

The double-deficit hypothesis: a comprehensive analysis of the evidence

The double-deficit hypothesis of developmental dyslexia proposes that deficits in phonological processing and naming speed represent independent sources of dysfunction in dyslexia. The present article is a review of the evidence for the double-deficit hypothesis, including a discussion of recent findings related to the hypothesis. Studies in this area have been characterized by variability in methodology--how dyslexia is defined and identified, and how dyslexia subtypes are classified. Such variability sets limitations on the extent to which conclusions may be drawn with respect to the double-deficit hypothesis. Furthermore, the literature is complicated by the persistent finding that measures of phonological processing and naming speed are significantly correlated, resulting in a statistical artifact that makes it difficult to disentangle the influence of naming speed from that of phonological processing. Longitudinal and intervention studies of the double-deficit hypothesis are needed to accumulate evidence that investigates a naming speed deficit that is independent of a phonological deficit for readers with dyslexia. The existing evidence does not support a persistent core deficit in naming speed for readers with dyslexia.     

Der Dopingdiskurs der 1950er und 1960er Jahre in den Leitmedien Der Spiegel und Die Zeit

Doping and antidoping are socially constructed, evolving and historically contingent phenomena relying on actors agreeing about allowed and deviant behaviour. Therefore, public discourse about doping represents an important part of the history of doping and antidoping. Content analysis of doping discourse in German quality media Der Spiegel und Die Zeit in the 1950s and 1960s shows that public attention for doping was rather low even though awareness increased due to the politicisation of sport and the rise of anabolic doping. Doping does not appear as a particular pressing but solvable problem. Moreover, doping is not linked to West German sport. In ethical terms, doping is perceived negatively. Neither does there exist a general mistrust in the sport bodies nor are sport bodies or sport policy clearly and resolutely requested to act. Therefore, the well-known 1969 article by Brigitte Berendonk marks a qualitative turn in public doping discourse.
