NARST: a lived history

In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living history that both shapes and was shaped by the biographies of its members.

Meeting kids at the school gate: The literacy and numeracy practices of a remote indigenous community

This paper reports on a qualitative study which generated detailed case study information about the transition experiences of seven Indigenous students as they moved from Year 7 in their community school to Year 8 in their new urban high school context (Rennie, Wallace, Falk & Wignell 2004). In particular the study aimed to document the literacy and numeracy practices valued in the home community, community school and urban high school and highlight any continuities and discontinuities between the various contexts. Data were collected using observations, document analyses and interviews. Students in the study participated in a number of different activities ‘outside of school’ in their home communities including hunting, art, ceremony, cooking, sport and play. There was evidence of literate and numerate practices embedded throughout these activities. The data also showed there were distinct differences in the kinds of knowledge valued in each context investigated. Cultural knowledge was valued in the home community whereas curriculum knowledge was valued in the school community. The students also built other bodies of knowledge through their participation in community activities. These were reflected in the school curriculum and included scientific knowledge, art knowledge, sport and recreational knowledge and work and domestic knowledge. This paper discusses the community literate and numerate practices, and highlights the continuities and discontinuities with the literate and numerate practices that are valued and privileged in the school curriculum.     

Effects of tactile stimulation on the initiation and maintenance of the following response in Japanese quail (Coturnix coturnix japonica)

Effects of tactile contact with an imprinting stimulus object on the initiation and maintenance of the following response in neonatal Japanese quail,Coturnix coturnix japonica, were examined. Tactile contact with an imprinting stimulus object was permitted during a preexposure period and/or during a following test. Results indicated that following was stronger when tactile contact was permitted during either the preexposure or test periods than when such contact was not given. Following occurred sooner when contact was permitted during the preexposure period than during following only, or when no contact was permitted. The greatest strength of following occurred when tactile stimulation was permitted during both preexposure and testing periods. It was concluded that the results support the hypothesis that tactile stimulation can facilitate both the initiation and maintenance of following behavior, and this is interpreted as being consistent with Schneirla’s (1965) theory.     

Spatial ability,visual imagery,and mathematical performance

116 Foundation Year Engineering Students, at the University of Technology, Lae, Papua New Guinea, were given a battery of mathematical and spatial tests; in addition, their preferred modes of processing mathematical information were determined by means of an instrument recently developed in Australia by Suwarsono.Correlational analysis revealed that students who preferred to process mathematical information by verbal-logical means tended to outperform more visual students on mathematical tests. Multiple regression and factor analyses pointed to the existence of a distinct cognitive trait associated with the processing of mathematical information. Also, spatial ability and knowledge of spatial conventions had less influence on mathematical performance than could have been expected from recent relevant literature.     

Making ‘Hope Practical’ Rather than ‘Despair Convincing’: feminist post‐structuralism,gender reform and educational change

This paper explores the work and effects of gender reform in schools through the use of feminist post‐structuralist theory. Focusing on the discourses designed to enhance girls’ post‐school options, it examines the ways in which teachers and students, particularly girls, write, read and rewrite these discourses and on the basis of this suggests some new directions for researching, theorising and practicing gender reform in schools. In particular, it raises questions about the ways in which feminist pedagogies in schools deal with the female body, difference, pleasure and pain.     

Early mathematics assessment: validation of the short form of a prekindergarten and kindergarten mathematics measure

In recent years, there has been increased interest in improving early mathematics curricula and instruction. Subsequently, there has also been a rise in demand for better early mathematics assessments, as most current measures are limited in their content and/or their sensitivity to detect differences in early mathematics development among young children. In this article, using data from two large samples of diverse populations of prekindergarten and kindergarten children, we provide evidence regarding the psychometric validity of a new theory-based early mathematics assessment. The new measure is the short form of a longer, validated measure. Our results suggest the short form assessment is valid for assessing prekindergarten and kindergarten children’s numeracy and geometry skills and is sensitive to differences in early mathematics development among young children.     

Free for All: A Case Study Examining Implementation Factors of One-to-One Device Programs

Despite significant investment in school one-to-one device programs, little is known about which aspects of program implementation work and why. Through a comparison of two implementation models, adopter-diffusion and saturation, and using existing data from the One Laptop per Child Australia laptop program, we explored how factors of implementation may affect device diffusion, learning and educational outcomes, and program sustainability in schools. In this article we argue that more focused research into implementation of one-to-one device programs, moving beyond comparisons of “devices versus without devices,” is needed to provide reliable data to inform future program funding and advance this area of research.     

Interactives and Visitor Learning

Abstract Interactives—computers and other multimedia components, physical manipulatives (including whole‐body and tabletop activities), and simulations—occur in all types of museums. There is considerable interest in the nature of the learning that happens when visitors use interactives. Museum professionals have enlisted constructivist theory to support the notion that interactive elements are invaluable components of any exhibition experience, and are effective learning tools that enable active visitor engagement. Interactives are also seen as vital to sustaining institutional image and expanding institutional popularity. Despite the increasing use of interactives in exhibitions and the substantial investments being made in their design and maintenance, there is a paucity of research as to whether these constructivist assumptions are supported. There is little work exploring visitors' perceptions of specific types of interactives, or the role of interactivity in the visitor experience generally. Museum staff thus have a limited ability to make informed decisions about the level and type of interactivity that might enhance exhibition experiences. This paper describes a collaborative effort in 2001 by researchers at the Powerhouse Museum (PHM), Sydney; the Institute for Learning Innovation (the Institute), Annapolis, Maryland; and Curtin University of Technology (Curtin) and Scitech Discovery Centre (Scitech), both in Perth, Western Australia. This study investigated two aspects of interactivity: 1) visitor perceptions of interactivity in two different contexts, a museum and a science center; and 2) the types of short‐ and long‐term learning that resulted from use of interactives in these two institutions.     

The influence of personalization on tag query length in social media search

Social content systems contain enormous collections of unstructured user-generated content, annotated by the collaborative effort of regular Internet users. Tag-clouds have become popular interfaces that allow users to query the database of these systems by clicking relevant terms. However, these single click queries are often not expressive enough to effectively retrieve the desired content. Users have to use multiple clicks or type longer queries to satisfy their information need.
