The mathematical strengths and weaknesses of children with dyslexia

This paper reports the findings of two related studies that examined the mathematical strengths and weaknesses of children with dyslexia. In study one, dyslexic children were compared to children without special educational needs on tests that assessed arithmetic fact recall, place value understanding and counting speed. Study two used the same methodology, but matched the dyslexic children with the non‐dyslexic children on a number of factors, including intellectual ability. This excluded the possibility that confounding variables accounted for the differences between the groups in study one. Both studies indicated that the dyslexic children had slower and less accurate number fact recall than the non‐dyslexic children, but had unimpaired place value understanding. The results for counting speed were more equivocal, but there was a trend for the dyslexic children to be slower counters. The results suggest that dyslexia is not normally associated with a general mathematical impairment, but rather an uneven profile of skills. This profile can be explained in terms of the phonological processing weaknesses associated with dyslexia. The finding that dyslexic children have a specific difficulty recalling arithmetic facts suggests that a teaching programme that emphasises mental methods may disadvantage them.     

Assessing the social and affective outcomes of inclusion

The systematic assessment of the social and affective outcomes of inclusion has been lagging behind the assessment of academic outcomes. This is particularly problematic in view of research evidence supporting concerns about peer rejection and bullying. In this article, Norah Frederickson and Elizabeth Simmonds, of University College London, and Lynda Evans and Chris Soulsby, from Foxwood Special School, report their evaluation of the social and affective outcomes of a special- mainstream school inclusion initiative that places particular emphasis on peer preparation. Measures completed by pupils were used to assess peer group inclusion, social behaviour, bullying and feelings of belonging at school. Results showed that pupils who had transferred from special to mainstream schools experienced positive social outcomes and none experienced peer group rejection. However, results were less positive for mainstream pupils with special educational needs and the authors discuss possibilities for development. Trends in peer reports of bullying suggest that there is no room for complacency and that ongoing monitoring is required.     

Evolution in educational change: A literature review of the historical core of the <Emphasis Type="Italic">Journal of Educational Change</Emphasis>

This literature review explored educational change trends as reflected in the first 15 years of the Journal of Educational Change (JEC), from 2000 to 2014. The examination of 52 articles accounting for 61% of the Journal’s historical citations indicated that the JEC has evolved through five periods, which relate to ‘waves of educational change’ beyond the Journal itself. At the center of this development there has been a process of de-centering of Anglo-American perspectives on educational reform, pushed both by an increasing pessimism among U.S. and U.K. scholars regarding their countries’ reforms and by systematic evidence that other educational systems are achieving better student learning outcomes. The aforementioned evolution also shows a shift from more conceptual works by the field’s historical leaders toward more empirical research conducted by emergent scholars. After discussing the predominant concept of educational change, the major silences in the reviewed literature, and what this evolution in the JEC says about the field of educational change at large, the paper ends reflecting on challenges as a new generation of scholars begins to enter the conversation.     

A case study of the mis-management of educational change: an interpretation from an affective standpoint

The paper describes a case study of the development and implementation of a policy to monitor teachers’ classroom practice in a secondary comprehensive school in Wales, UK. The change process is interpreted from an affective standpoint to explain how the experience of feelings and emotions shapes organisational practice. In particular, the interpretation illustrates how affective experience may influence the distinction between espoused and in use theories, which may in turn have an effect on individual and organisational resistance to change and the success of the implementation. Differences between espoused and in use theories may increase both organisational anxiety and resistance in a self-sustaining cycle. We argue that when the anxieties and emotions of organising in schools are allowed to surface in the change process and are reflected upon, the espoused and in use theories are more likely to correspond and organisational anxiety and resistance to change to decrease.     

Action learning in John Lewis

A small group of training professionals within the John Lewis Partnership set up an action learning group about 2 years ago. The main aim was to explore the technique for our own learning and development. The timing and lifespan of the group reflected the generally strategic and long-term nature of our projects. One of these was to introduce action learning to a group of operational managers in one of our department stores. Key benefits which arose for this group were: the opportunity to spend time thinking about one aspect of work in a focused way; the learning that arose both about the action learning experience as well as about our projects; the challenge provided by the group, which proved an incentive to move work along quickly; the bonds of trust and support established which have continued after the group ended it's life. We have been able to learn from our own experience and that of the pilot operational managers group to help us expand both the use and the usefulness of action learning for the organization.     

Stem Cells and Society: An Undergraduate Course Exploring the Intersections among Science, Religion, and Law

The intersection of science and our society has led to legal and ethical issues in which we all play a part. To support development of scientific literacy, college science courses need to engage students in difficult dialogues around ethical issues. We describe a new course, Stem Cells and Society, in which students explore the basic biology of stem cell research and the controversy surrounding it. As part of the course, we highlight the nature of science, looking at the methods and norms within the scientific community. To gain a perspective on the current stem cell controversy, we examine the public debates in the 1970s surrounding in vitro fertilization, the stem cell initiative in Missouri, and the personal and religious viewpoints that have emerged relative to the stem cell debate. In the Stem Cells and Society course, students are challenged to develop and clarify their own personal positions concerning embryonic stem cell research. These positions are grounded in science, religion or personal philosophy, and law.     

Multimedia learning and individual differences: Mediating the effects of working memory capacity with segmentation

Research in multimedia learning lacks an emphasis on individual difference variables, such as working memory capacity (WMC). The effects of WMC and the segmentation of multimedia instruction were examined by assessing the recall and application of low (n=66) and high (n=67) working memory capacity students randomly assigned to either a segmented instruction (SI) or non-segmented instruction (NSI) version of a multimedia tutorial on historical inquiry. WMC was found to have a significant, positive effect on participants' recall and application scores; however, the use of segmentation mediated the effects of WMC to allow learners with lower WMC to recall and apply equal to those with higher WMC.     

Optimisation of the chain drive system on sports motorcycles

This paper investigates the optimisation of the chain drive system on sports motorcycles. Recently there has been the development of a chain transmission efficiency model that is suitable for motorcycles. The new model is used to predict the efficiency of 600cc sports motorcycle at different speeds. The transmission efficiency is estimated to be between 96 and 99% for speeds less than 75 mile/h. Between 75 and 150 mile/h the transmission efficiency can be as low as 85% due to inertial tension. The transmission efficiency model presented in this paper enables optimisation of sprocket and chain sizes. In general, large sprockets are better at low speeds and smaller sprockets are better at high speeds. The optimum chain size is the chain with the smallest pitch that can meet the torque and power requirement. The sprocket centre distance also has a big effect on efficiency and it is important to use an effective installation procedure. In particular, it is important to set a chain up when the rear wheel axle, front crank and swing arm bearing are all in-line.     

System Performance and Natural Language Expression of Information Needs

Consider information retrieval systems that respond to a query (a natural language statement of a topic, an information need) with an ordered list of 1000 documents from the document collection. From the responses to queries that all express the same topic, one can discern how the words associated with a topic result in particular system behavior. From what is discerned from different topics, one can hypothesize abstract topic factors that influence system performance. An example of such a factor is the specificity of the topic's primary key word. This paper shows that statements about the effect of abstract topic factors on system performance can be supported empirically. A combination of statistical methods is applied to system responses from NIST's Text REtrieval Conference. We analyze each topic using a measure of irrelevant-document exclusion computed for each response and a measure of dissimilarity between relevant-document return orders computed for each pair of responses. We formulate topic factors through graphical comparison of measurements for different topics. Finally, we propose for each topic a four-dimensional summarization that we use to select topic comparisons likely to depict topic factors clearly.
