The Structure of Discourse in Collaborative Learning

The authors examined the types of discourse structures that emerge during peer learning and the ways in which those structures are related to learning. One hundred and five 5th graders learned about writing conclusions that summarized the results of experiments they had conducted with electrical circuits. In groups of 4, they discussed the quality of 3 conclusions. The discourse structure of the discussions could be readily characterized as a network of arguments and counterarguments. The quantitative measures of the quality of those argument structures were positively related to improvement in the students' ability to write their own conclusions. In addition, the students who simply discussed whether the 3 conclusions were OK or not OK generated less complex argument structures than the students who discussed which of the 3 conclusions was best and which was worst. The results demonstrate the importance of considering the structure of peer discourse as a mediator of what students learn from peer interactions.     

LEA support services for special educational needs provision and management

The National Foundation for Educational Research recently undertook research on the impact of delegation on local authority support services for special educational needs. This paper presents data on the provision offered by these services and the way in which they are managed. In particular, it examines how support is targeted, the extent and profile of service staff, mechanisms for the referral of pupils for support from the services, management structure, staff deployment and the professional development of service staff, and service monitoring, review and evaluation. Ways in which support services have developed in the 1990s, and their challenges for the next decade in the light of developments in the governance of education and the local policy context, are discussed.     

The Museum of Irish Industry,Robert Kane and education for all in the Dublin of the 1850s and 1860s 1

The Museum of Irish Industry in Dublin, in its short existence (1845–1867) facilitated the access of ordinary people to popular scientific education, became a cause célèbre and was defended by popular protest when the government recommended its abolition in 1862. Its Director, Sir Robert Kane (1809–1890) was not only an advocate of popular industrial education but also had a lifelong commitment to ‘united’ (or non‐denominational) education believing that only this type of education would achieve the ultimate result of tolerance, religious peace and national prosperity in Ireland. From 1854 a Government School of Science was part of the museum’s educational activities and from 1854 to 1867 the professors attached to the museum offered courses of lectures, both ‘popular’ and formal courses, on physics, chemistry, botany, zoology and geology, and in applied science. With its exhibition collections, its laboratories and the range of educational courses organised by its staff the museum was one of the British government’s most innovative experiments in education in Victorian Ireland. Beyond this, Kane’s determination that the courses offered by the museum would be available to all, with no distinction of creed or gender, distinguishes this institution as a pioneer in providing equal access to scientific education to all in the mid‐nineteenth century. This article will explore the role this unique education played in the educational and social life of mid‐Victorian Dublin.     

Effect of the number of scale points on chi‐square fit indices in confirmatory factor analysis

This article investigates the effect of the number of item response categories on chi‐square statistics for confirmatory factor analysis to assess whether a greater number of categories increases the likelihood of identifying spurious factors, as previous research had concluded. Four types of continuous single‐factor data were simulated for a 20‐item test: (a) uniform for all items, (b) symmetric unimodal for all items, (c) negatively skewed for all items, or (d) negatively skewed for 10 items and positively skewed for 10 items. For each of the 4 types of distributions, item responses were divided to yield item scores with 2,4, or 6 categories. The results indicated that the chi‐square statistic for evaluating a single‐factor model was most inflated (suggesting spurious factors) for 2‐category responses and became less inflated as the number of categories increased. However, the Satorra‐Bentler scaled chi‐square tended not to be inflated even for 2‐category responses, except if the continuous item data had both negatively and positively skewed distributions.     

The effects of a single night of complete and partial sleep deprivation on physical and cognitive performance: A Bayesian analysis

ABSTRACT

This study investigated the effects of complete and partial sleep deprivation on multiple aspects of athletic performance. Ten males completed a cognitive function test, maximal handgrip strength, countermovement jump (CMJ) and a 15 min all out cycling test to assess aerobic performance. These tests were performed following 3 different sleep conditions; normal sleep (CON), a 4 hr sleep opportunity (PART) and complete sleep deprivation (DEP). Data were analysed using a Bayesian multi-level regression model to provide probabilities of impairment (p = %). Aerobic performance, CMJ and handgrip strength were impaired by 11.4% (p = 100%), 10.9% (p = 100%) and 6% (p = 97%) following DEP, while aerobic performance and CMJ were highly likely impaired by 4.1% (p = 90%) and 5.2% (p = 94%) following PART. Cognitive reaction time was not impacted by PART or DEP. In contrast the accuracy of responses was highly likely impaired by 2% (91) following DEP, while there was less certainty of impaired accuracy following PART (?1%, p = 73). Multiple aspects of physical and cognitive performance were impacted by sleep deprivation. The greatest detrimental effects were seen for aerobic performance and CMJ. Partial sleep deprivation equating to 4 hrs of sleep causes subtle, but potentially important negative impairments on athletic performance.     

Parents’ Perspectives on Surf Therapy for Children with Disabilities

This qualitative study was designed to understand parents’ perceptions of their children’s participation in an inclusive surf therapy programme in the United States. Ten parents and one caregiver were interviewed about theirs and their children’s experience in the surf programme. Parent discussions centred on the child, parent/caregiver, instructor and challenges of parenting. Results indicate that parents perceive surf therapy to positively impact their child physically, socially and behaviourally. Findings also suggest cost, an inclusive, family-centred approach and opportunities for socialisation with other families were important to parents’ satisfaction.     

Assessing learner‐centredness through course syllabi

One attempt to revitalise undergraduate education has been by shifting the dominant pedagogy to a learner‐centred focus and supporting an emphasis on the scholarship of teaching and learning. The discussion regarding efforts to refocus undergraduate education to be more intentional by moving towards a learner‐centred paradigm is encouraging, yet it is crucial to acknowledge that most of the effort and literature on the learner‐centred paradigm and the scholarship of teaching and learning have necessarily focused on strategies for the classroom. It is equally important for administrators to consider the impact of the paradigm shift on their roles. Assessment and evaluation are the very core of the learner‐centred paradigm. Assessment is both the single‐most important gage of learning that drives the educational process and the most effective means of implementing institutional change. In this article, the authors offer a means of assessing the degree of learner‐centredness in current teaching practices through a systematic review of course syllabi. Using a rubric developed for this purpose the authors have reviewed course syllabi in order to develop a benchmark for the degree of learner‐centredness present in current teaching practices and employed the results as a vehicle for planning professional development.     

Computational What? Relating Computational Thinking to Teaching

Computational thinking is one of the skills critical for successfully solving problems posed in a technology driven and complex society. The limited opportunities in school settings to help students develop computational thinking skills underscores the need for helping teachers integrate it in their practices. Besides developing the knowledge of technology, content, and pedagogy, teachers need to recognize the relevance of computational thinking to their teaching, a factor influencing their future practice with it. Drawing from the literature on problem-solving and TPACK framework, this paper discusses strategies, including content-specific examples, problem-solving nature of computational thinking, and the methods of teaching problem-solving for enabling teachers to make the connections between computational thinking and their practices.
