Productive Communication in an Afterschool Engineering Club with Girls Who are English Language Learners

This article the learning of girls who were in a co-ed after school engineering club related to the project: Designing Vital Engineering and Literacy Practices for Science, Technology, Engineering, and Math for Elementary Teachers and Children (DeVELOP STEM ETC). While few girls grow up to become engineers in the US, recently more attention has focused on practices that engage girls in order to grow interest in engineering and engineering careers. In this article, we follow three eight and nine-year-old girls (3rd graders). We illustrate how key features of the Engineering Design Process intersect with a multimodal model of Productive Communication to help the girls enact identities as girls and as engineers as they design and build a bridge. We argue that to enact the Next Generation Science Standards, particularly those related to engineering, engineering and STEM educators must attend to the disciplinary literacies and communicative modes of girls and other under-represented minorities. This is also particularly important for learners who are still new to learning English and who may benefit from multimodal interactions and diverse opportunities to learn.     

Predicting word-spelling difficulty in 7- to 11-year-olds

Some languages have simple grapheme-phoneme codes in which there is a one-to-one mapping, making them easy to teach and learn, while others have more complicated structures and are more difficult for teachers and students. There is now an increasing number of studies which demonstrate that readers in more transparent orthographies such as Italian, Spanish, Turkish, Greek and German have little difficulty in decoding written words, while English children have many more problems. Increasingly, lack of orthographic transparency in English is seen as having a powerful negative effect on the development of literacy skills in English-speaking children. In the present study, the word factors associated with poor spelling in 5 school year-groups (ages 7 to 11 years) are identified as: (a) frequency of the word in the English language, (b) length of the word and (c) a measure of the phoneticity of the word. The concept of word phoneticity is explored and data is presented illustrating the predictive model of spelling. The implications the model has for teaching and learning English are discussed, with particular reference to the beneficial effects that greater orthographic transparency would have for children.     

Diagnosis for Covariance Structure Models by Analyzing the Path

When a covariance structure model is misspecified, parameter estimates will be affected. It is important to know which estimates are systematically affected and which are not. The approach of analyzing the path is both intuitive and informative for such a purpose. Different from path analysis, analyzing the path uses path tracing and elementary numerical analysis to identify affected parameters when a 1-way or 2-way arrow in a path diagram is omitted. It not only characterizes how a misspecification affects model parameters but also facilitates a good understanding of the relation among different parts of the model. This article introduces and studies this technique and, for commonly used models, provides detailed analysis to identify the directions of change for various model parameters. Examples based on real data show that the technique of analyzing the path can reliably predict the direction of change in parameter estimates even when the true model is unknown. Conditions that interfere with the results are also discussed and advice is provided for its proper application.     

The preschool bathroom: making ‘problem bodies’ and the limit of the disciplinary regime over children

In this paper we study the effects of power in a bathroom, which is a rarely analysed space in preschools, using empirical examples from a semi-ethnographic study conducted in New South Wales, Australia. We demonstrate that educators’ understanding and practices mostly consider their own positioning in discourses and come short in accounting for children’s practices in and expressed views on the bathroom. Educators also remain distant from children’s bodily experiences. The interplay of the open architectural design of the bathroom space and dominant discourses operating in the preschool constitute some children as ‘problem bodies’ apparently requiring (and justifying) direct intervention. Following this reasoning we argue that the surveillance, regularisation and normalisation in the bathroom is far from total, which leads us to question the adequacy of understanding the bathroom as forming a part of a modern (disciplinary) institution.     

Teachers,Arts Practice and Pedagogy

What are possible overlaps between arts practice and school pedagogy? How is teacher subjectivity and pedagogy affected when teachers engage with arts practice, in particular, theatre practices? We draw on research conducted into the Learning Performance Network (LPN), a project that involved school teachers working with the Royal Shakespeare Company and the University of Warwick. The aim of the commissioned research was to look at the effects on teacher development, focusing on the active rehearsal room pedagogic techniques and ensemble methods of exploring Shakespearean text and performance. The practices of working as an ensemble through rehearsal room pedagogy were central to the LPN. Our interest is in looking for possible shifts in teachers’ subjectivity, their self-perception. What affordances, limitations, accommodations and tensions are experienced by the teachers in transposing work from the rehearsal room to the classroom? We draw on a range of cultural theories that provide complementary perspectives on aspects of subjectivity; these include Vygotskian approaches to the psychology of art and acting. Raymond Williams’s work on the ‘dramatized society’ and Jacques Rancière’s work on spectatorship and pedagogy. Data in the form of excerpts from field notes, taken in an introductory workshop where teachers worked with theatre practitioners, and from transcribed interviews with participants in the project are used to provide evidence of shifts in perspective, self-perception and pedagogic practice.     

Effects of weighted sled towing on ground reaction force during the acceleration phase of sprint running

Abstract

Athletes use weighted sled towing to improve sprint ability, but little is known about its biomechanics. The purpose of this study was to investigate the effect of weighted sled towing with two different loads on ground reaction force. Ten physically active men (mean ± SD: age 27.9 ± 1.9 years; stature 1.76 ± 0.06 m; body mass 80.2 ± 9.6 kg) performed 5 m sprints under three conditions; (a) unresisted, (b) towing a sled weighing 10% of body mass (10% condition) and (c) towing a sled weighing 30% of body mass (30% condition). Ground reaction force data during the second ground contact after the start were recorded and compared across the three conditions. No significant differences between the unresisted and 10% conditions were evident, whereas the 30% condition resulted in significantly greater values for the net horizontal and propulsive impulses (P < 0.05) compared with the unresisted condition due to longer contact time and more horizontal direction of force application to the ground. It is concluded that towing a sled weighing 30% of body mass requires more horizontal force application and increases the demand for horizontal impulse production. In contrast, the use of 10% body mass has minimal impact on ground reaction force.     

Distributed leadership of school curriculum change: an integrative approach

Since its inception in 1999, the distributed leadership framework of Spillane, Halverson, and Diamond [2004. “Towards a Theory of Leadership Practice: A Distributed Perspective.” Journal of Curriculum Studies 36 (1): 3–34. doi:10.1080/0022027032000106726] has supported research into leadership and change in schools. Whilst the conceptual integrity of the framework is sound, research based upon its premises has attracted some criticism. The research has had a narrowed focus which has not generally reflected the inseparability of the elements of the framework and the situation within which leadership is enacted. In addition, it often fails to account for the complexity of critical elements of the environment such as micropolitics. This position paper proposes a reconfiguration of the distributed leadership framework as a research framework in response to this critique. The paper asserts that this new perspective that is presented is able to respond to the critique through an integrated approach that encompasses situation, social distribution and task enactment and which supports an integrated approach to research methodology. This adapted framework has the potential to more fully support research design that is actuality holistic and embedded in the context.     

Stuart Hall at the Open University

ABSTRACT

Accounts of the influence of Stuart Hall's thought on subsequent developments tend to neglect his work at the Open University. This unjustifiable neglect is illustrated by the example of his contribution to the course on Beliefs and Ideology, especially his article on 'Religious ideologies and social movements in Jamaica' [Hall, S. (1985). Religious ideologies and social movements in Jamaica. In R. Bocock & K. Thompson (Eds.), Religion and ideology (pp. 269–297). Manchester, UK: Manchester University Press].
