The use of tinted lenses to alleviate reading difficulties

An increasing number of optometrists are offering assessments using the Intuitive Colorimeter (Wilkins, Nimmo‐Smith and Jansons, 1992) to determine whether children who have reading difficulties might benefit from the use of tinted lenses. Suggestions have been made in the media that tinted lenses may provide a ‘cure’ for developmental dyslexia, and there have been many anecdotal accounts of improvements in reading following their use (e.g. Brace, 1993). However, such extreme claims are not typical of the scientific literature supporting the use of tinted lenses. This article provides an overview of the research into the use of tinted lenses for the amelioration of reading difficulties. The electronic databases searched for this review were BIDS, MEDLINE, PsychInfo, PsychLit and Science Direct. Key search terms used were coloured (colored) lenses, Irlen lenses, scotopic sensitivity and visual deficits in combination with the term ‘reading difficulties’.     

Social Space,Gender Inequalities and Educational Differentiation

The spatial dimensions of social interaction and reproduction have received increasing attention from sociologists in recent years. However, these issues remain largely implicit in most studies of classrooms, schools and the education system. In this paper, I argue that the study of social space should be integral to analyses of the relationship between educational differentiation and social reproduction. After examining the position of space in Giddens's theory of structuration, I focus on how space is used in schools as a resource in the production of unequal gender relations. Space is viewed not simply as a context in which interaction occurs, but as a phenomenon which both produces, and is produced by, gendered power relations.     

Sonification of numerical data for education

ABSTRACT

Sonification is the use of non-speech audio to convey information. In this article, sonifications are representations of plots aimed at improving the accessibility of teaching materials. The electronic nature of sonifications means that they can be deployed to students via teaching interfaces such as virtual learning environments. We describe a two-phase study that explores sonifications of plots as a teaching tool in the context of distance learning in STEM. The overall objective of these two phases was to begin to assess the suitability of audio versions of graphs as a teaching tool for non-sighted and sighted students. In the first phase the effectiveness of sonifications within a small group of participants who took part in activities like those encountered in a distance learning setting was explored. We found that even though sonifications were new to them, participants were able to use them to gain impressions of the corresponding plots. The second phase deployed sonifications to all students on an Open University (OU) module. Although many of the students who chose to respond did so negatively, some found the sonifications an interesting augmentation of the plot. Overall, we demonstrate that for a subset of students, information in a plot can be communicated using sonifications.     

Didactising: Continuing the work of Leen Streefland

In this paper we present three cases of instructional design that illustrates both horizontal didactising, the activity of using already established principles to design instruction, and vertical didactising the activity of developing new tools and principles for instructional design. The first case illustrates horizontal didactising by elaborating how the constructs chains of signification and models were used to design an instructional sequence involving linear growth. The second and third cases illustrate vertical didactising by developing argumentation analyses and generative listening, respectively, as instructional design tools. In the second case, argumentation analyses emerge as a tool that other designers can use to anticipate the quality of conversations that can occur as students engage in tasks prior to implementing the instructional sequence. The third case develops the notion of generative listening as a conceptual tool within the context of designing differential equations instruction to gain insights into what are, for students, experientially-real starting points that are mathematical in nature and to provide inspirations for revisions to instructional sequences. This revised version was published online in August 2006 with corrections to the Cover Date.     

Flavor evaluative conditioning and contingency awareness

The relationship between flavor evaluative conditioning and contingency awareness was examined in two experiments using flavored drinks. In Experiment 1, one flavor was always paired with sugar and the other with bitter tween (polysorbate20) during conditioning. In a subsequent test phase, participants tasted the two flavors, and their evaluative ratings indicated an overall preference for the sugar-paired flavor. Moreover, participants were generally able to report which flavor had been paired with sugar and which with tween. This finding was replicated and confirmed in Experiment 2A. Furthermore, in both experiments, evaluative conditioning was seen only in those participants who were aware of the contingencies. Experiment 2B demonstrated that evaluative conditioning does not occur to colors, although participants are contingency aware. The differences between the present findings and prior studies, in which apparently unaware flavor conditioning has been found, are discussed.     

Promises and Pitfalls of Adapting Utility Value Interventions for Online Math Courses

A growing body of research suggests that interventions promoting students’ utility value for a subject can improve their academic outcomes. However, numerous questions remain regarding how much to adapt prior intervention materials to promote utility value in new educational contexts and how implementation constraints of an educational context may impact the success of these interventions. In this study, using a design-based process we developed and tested three utility value interventions in a new educational context (online high school math). We found that one of the interventions increased utility value compared to control conditions, but we also encountered constraints on intervention implementation that limited the effectiveness of our intervention and the conclusions we could draw from this work. We use our experience as a case study to illustrate the costs and benefits of making certain implementation choices when partnering with practitioners to administer utility value interventions in new contexts.     

Culture,technology and local networks: towards a sociology of ‘making’ in education

This article is about ‘making’ in education. Often associated with software programming (as in ‘digital making’), making can also involve creating or modifying physical technological artefacts. In this paper, making is examined as a phenomenon that occurs at the intersection of culture, the economy, technology and education. The focus is not on the effects on cognitive gains or motivations, but on locating making in a social, historical and economic context. Making is also described as a form of ‘material connotation’, where connotation refers to the process through which the technical structure of artefacts is altered by culture and society. In the second part of the paper, the theoretical discussion is complemented by a case study in which making is described as a networked phenomenon where technology companies, consultants, volunteers, schools, and students were all implicated in turning a nebulous set of practices and discourses into an educational reality.     

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.
