Children's conceptions of the changes of state of water

Children are very familiar with water, ice, and steam as these things have been part of their lives since they first crawled into the kitchen. In this study children's conceptions about familiar phenomena associated with water, e.g., evaporating, condensing, boiling, and the melting of ice, were investigated using a clinical interview technique. The prevalence of specific views at particular age levels was also studied. The results of the investigation indicate that children do have ideas about the changes of state of water which are quite different from the views of scientists. It would also appear that these ideas can sometimes be influenced in unintended ways by science teaching. The implications of these findings for teaching are discussed.     

Are academic outcomes of higher education provision relevant to and deliverable in the workplace setting?

Current developments in higher education strongly indicate that the way ahead in many disciplines is much closer co-operation between academia and industry. There is growing demand that recognition should be given to learning, irrespective of the environment in which it occurs.This article reflects on what are deemed to be essential components of a degree, and considers how they might be transformed into forms suitable for demonstration in the work environment. The discussion is supported by findings of a survey carried out in conjunction with a development - Structured Industrial Practice Studies - which integrates academic learning and learning in the work environment for full-time students. The findings, however, are of relevance beyond the particular model of learning and mode of attendance. There appears to be potential for achieving in the workplace aspects of courses which, in recent times, have been the prerogative of higher education establishments. However, such potential is variable between working environments and is dependent on higher education providers adapting to different structures in delivery.     

Science Without Literacy: A ship without a sail?

This article argues that reading, writing and argument are central to any conception of science as it is currently constituted. Moreover, it is through the texts of science, popular accounts or journalistic reported versions that the majority of the public interact with and consider the implications of the findings that science presents. However, the study of the language of science, science's epistemic base and the cultural norms and values that underpin its practice are currently considered only marginal to the teaching of science. Rather, the specialised laboratories provided for science teachers and the narrow conception of science embodied in the curriculum gives pre-eminence to science as an empirical activity in the naive belief that this is central to understanding the nature of science. The consequent failure to recognise the centrality of language, literacy and argument to science education leaves the majority ill equipped to become critical consumers of science. Change requires a concerted attempt to reconceptualise the priorities for science education through a mix of new curricula, new strategies and last, but not least, new modes of assessment.     

AMERICAN UNIVERSITY LIBRARIES IN THE COMPUTER AGE

The author has presented a rapid overview of the uses of the new information technologies in various aspects of library management and utilization in the United States of America. As early as the 1950's, as concerned librarians had come to realise that manual methods would no longer suffice to cope with the demands being made on libraries, they turned increasingly to automation. Libraries were innovators with regard to the development of large databases and the users of innovations with regard to the development of communications technologies. The latter, the new information and communications technologies (NICT's), are playing increasingly important roles with regard to the operation of libraries in the areas of acquisitions, cataloguing, circulation, reference, administration, inter‐library links including shared cataloguing, resource sharing, and inter‐library loan (now thought of as document delivery). The introduction of these same technologies has required that changes be made in the way librarians are trained, that older practising librarians have their training upgraded, and that library clients be trained in techniques of computer use and information retrieval. For the future, the uses made of the NICT's are bound to expand, leading to increased electronic publishing and distribution and to greater integration of indexes and catalogues. University libraries will increasingly become parts of campus‐wide communications and information networks.     

Developing a Deeper Involvement with Science: Keith's Story

Much research in science education has focused on the conflicts that exist between individuals' ways of knowing the world and science. We have been left without an image of the compatibility or congruency that is necessary for science to occupy a fundamental position in a person's life. In this study we argue that Keith, a Jamaican American pre-service teacher, provides us with such an image. Using narrative, we trace the development of Keith's relationship with science over time and space in order to understand how Keith has constructed an identity through science amid the larger structures and contexts that comprise his life. We believe Keith's stories of practicing science in and out of the classroom illustrate how science, while taking an essential position in his lifeworld, extends and articulates Keith's subjective stances on experience. As part of his lifeworld, Keith finds a sense of value in science that turns it into a discipline that is part of the person he both is and wants to be and the world he wants to shape as a teacher. Richard Kozoll is an assistant professor of science education at the School of Education of DePaul University. His research interests include students' identity constructs as a means to understand engagement with and participation in science and inform inclusive science teaching practices. An additional line of research includes the use of narrative in science education research. Margery Osborne is an Associate Professor in the College of Education at the University of Illinois at Urbana-Champaign. She teaches early childhood and elementary science education courses. Her research interests, located within the intersections constructed between ideas of reflective practice and research on critical and feminist pedagogy, include exploring the dynamic and complex nature of teacher knowledge.     

Lifewide learning in the city: novel big data approaches to exploring learning with large-scale surveys,GPS, and social media

ABSTRACT

Despite UNESCO’s Learning Cities agenda, which argues for the mobilisation of resources to promote education across all sectors and environments, there is little evaluative research on Learning City engagement which is both naturalistic and empirically rigorous. The research on informal adult learning in urban contexts is particularly sparse. This paper provides a case study of informal learning and lifewide literacies amongst Glaswegian adults using three distinct approaches to data collection: a household survey capturing rich data on learning attitudes, behaviours, and literacies; GPS trails that track mobility around the city; and the capture of naturally occurring social media. The work operationalises Learning City indicators, and explores domains beyond education, some of which have not previously been considered in surveys of adult learning, for example, physical mobilities and transportation patterns. We use theoretical concepts of social identity and capital to situate inclusion within explanatory frameworks of marginalisation in less tangible domains of informal learning using multi-stranded data. A triangulated analysis of city-wide participation in lifewide learning reveals a demographic picture of groups marginalised from learning opportunities and practices. We conclude with a call for new approaches to exploring learning participation which offer novel methods to evidence informal learning and lifewide literacies.

What are secondary students’ expectations for teachers in virtual school environments?

A recent evaluation of the new North Carolina Virtual Public School (NCVPS) in the USA revealed numerous expectations for virtual school teachers from secondary students. Specifically, students expected their teachers to actually teach rather than moderate a course shell, supplement course shells with content and projects that illustrate relevance, provide for both content and peer interaction, and respond to questions and provide feedback quickly. The data suggest a possible content‐related interaction where a limited course shell can be bolstered by a proactive teacher, but potentially flounder among teachers who do not expect or know how to supplement an online course. Data further suggest a potential communication‐related interaction where increased opportunities for student–student and student–teacher interaction could potentially decrease the actual or perceived need for individualized attention that is particularly challenging for virtual teachers to provide. These results can be used to establish teacher expectations and design professional development experiences that prepare teachers to undertake divergent roles unique to online instruction.     

Common Assessment Framework (CAF) – early views and issues

This study explores the profile of Common Assessment Framework (CAF) assessments and the perceptions of assessors during the early phase of its implementation. Whilst there was diversity in who completed CAFs, schools undertook the most. Headteachers and other school staff completing the assessment felt that the questions tended to be intrusive and they feared this might damage their relationship with parents. Assessments proved time consuming and completers tended to go on to become the Lead Professional. Comments suggested some people were avoiding the completion of CAFs because of fears about the increased workload. There were, however, positive views about the rigour of the process and it had tended to serve to prompt positive dialogue between agencies. There were genuine attempts to involve children in the process.
