Electrochemistry plays an important role in curricula, textbooks, and in everyday life. The purpose of the present study was to identify and understand secondary‐school students' problems in learning electrochemistry at an introductory chemistry level. The investigation covered four areas: (a) electrolytes, (b) transport of electric charges in electrolyte solutions, (c) the anode and the cathode, and (d) the minus and plus poles. Written tests were given to high‐school students in five cycles. The population from which random samples were drawn totalled 15,700 subjects. Students were asked to select the correct answers and to justify their choices. It was found that students based their reasoning on four alternative concepts: (a) During electrolysis, the electric current produces ions; (b) electrons migrate through the solution from one electrode to the other; (c) the cathode is always the minus pole, the anode the plus pole; and (d) the plus and minus poles carry charges. The results suggest a teaching strategy in which students first experience and learn about electrochemistry concepts. In the second step, appropriate concept terms are added, and students then are confronted with the alternative concepts described in this article. © 2006 Wiley Periodicals, Inc.

Environmental education research in Southern Africa: Dilemmas of interpretation     

Annette Gough  Noel Gough 《Environmental Education Research》2004,10(3):409-424

These multiple framings of our reflections on environmental education research in southern Africa are written as dilemmas of interpretation that aim to disrupt any temptation to generalise or essentialise its qualities and characteristics. Recognising that research is a textual practice, we use J. M. Coetzee's portrayal of the dilemmas faced by African novelists as a point of departure in reflecting on the changing landscape of environmental education research in southern Africa as we have experienced it over six years. We provide readings framed by reference to post-colonialism, changing epistemologies and methodologies, contexts of transformation and tension, the influence of international organisations such as the United Nations and its instrumentalities, and concerns about human rights and accountability. We conclude by affirming the post-colonialist trajectories of environmental education research in southern Africa and speculating on the distinctive possibilities that recovering ubuntu (an ethic of sharing and hospitality) might offer to researchers in this region.  相似文献   

The Virtual Game: Objects, Groups, and Games in the Works of Pierre Levy     

Ronald E. Day 《The Information Society》1999,15(4):265-271

This article critically engages the theme of the game as a model for identity, community, and the meaning and function of objects in a recent work by Pierre Levy. Two of Levy's books have recently appeared in English translation, making this a timely moment to return to this theme that resonates throughout cultural modernity, especially in the areas of business, the military, sports, and, of course today, in digital software and network design.  相似文献

Re-thinking school–university partnerships: A Swedish case study     

Christopher Day 《Teaching and Teacher Education》1998,14(8):807-819

All trends in educational reform point away from the traditional isolation of teachers and teacher educators from their colleagues and from other stakeholders towards an increased sense of being in rather than outside the broader community. In the case of relationships between universities and schools, however, co-operation and collaboration is often complicated by their different cultures and traditions. As yet, there have been few systematic attempts to conceptualise the territory for teacher and school level development and change in relation to the sustained strategic roles which universities may play. This paper presents the results of an independent evaluation of an innovative cluster of seven partnership projects between teachers, schools, and researchers and teacher educators in a university in Sweden. It concludes that differentiated strategic partnerships are necessary in order to meet the different, ideological, generative and capacity building needs of schools and teachers.  相似文献

The Developmental Sequence and Relations Between Gesture and Spoken Language in Toddlers With Autism Spectrum Disorder     

Meagan R. Talbott  Gregory S. Young  Jeff Munson  Annette Estes  Laurie A. Vismara  Sally J. Rogers 《Child development》2020,91(3):743-753

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words.  相似文献   

How teachers’ individual autonomy may hinder students’ academic progress and attainment: Professionalism in practice     

Christopher Day 《British Educational Research Journal》2020,46(1):247-264

This article reports a 3-year case study of a primary school in England, in which a recently appointed principal attempted to build ‘collegial professional autonomy’ (Nordic Journal of Studies in Educational Policy, 2 , 2015, 20) within a push to improve students’ progress and attainment. The research examined the tensions between staff who embraced the principal's agenda for collegially agreed change, and whose students’ academic progress and performance improved over a 3-year consecutive period when measured in terms of students’ entry-level attainment and socio-economic factors, and staff who asserted their right to ‘individual professional autonomy’ and whose students’ academic progress and attainment declined. The research: (i) challenges claims that reform necessarily results in school cultures of compliancy, de-professionalisation and the technicisation of teaching; (ii) raises issues concerning the pedagogical leadership of principals in a devolved, ‘self-governing’ school system; and (iii) questions teachers’ entitlements to individual professional autonomy where this is associated with students’ continuing academic underperformance.  相似文献   

Transforming University Practice Through ICT – Integrated Perspectives on Organizational,Technological, and Pedagogical Change     

Lone Dirckinck-Holmfeld  Annette Lorentsen 《Interactive Learning Environments》2013,21(2):91-110

The article focuses on the use of information and communication technology (ICT) for strengthening and transforming university practice in line with the social and technological conditions of the new ideas for interactive universities. The purpose is to use ICT as a change-agent in order to establish new practices – new pedagogical methods, new methods for collaboration and new forms of interplay between physical and virtual learning environments. The article is based on an ongoing case in which both the authors have been engaged: the IT Innovation project (ITI) and E-learning Lab North Jutland (ELL) at Aalborg University in Denmark. The article presents the different initiatives and strategies for innovation of the university and subsequently discusses the work in the perspective of organizational learning and planning theory.  相似文献
