In an attempt to widen the scope of school chemistry teaching, the authors have developed an interdisciplinary unit on the immune system. The main features of this unit are described, covering both its content and the pedagogical strategies employed in it. A brief summary of the results of the trial implementation of the unit is also presented. 相似文献

ABSTRACTIn this study, we explore the issues and challenges involved in supporting students’ learning to discern relevant and critical aspects of determining oxidation states of atoms in complex molecules. We present a detailed case of an interaction between three students and a tutor during a problem-solving class, using the analytical tool of practical epistemology analysis (PEA). The results show that the ability to make relevant distinctions between the different parts of a molecule for solving the problem, even with the guidance of the tutor, seemed to be challenging for students. These shifts were connected to both purposes that were specific for solving the problem at hand, and additional purposes for general learning of the subject matter, in this case how to assign oxidation states in molecules. The students sometimes could not follow the additional purposes introduced by the tutor, which made the related distinctions more confusing. Our results indicate that in order to provide adequate support and guidance for students the tutor needs to consider how to sequence, move between, and productively connect the different purposes introduced in a tutor-student interaction. One way of doing that is by first pursuing the purposes for solving the problem and then successively introduce additional, more general purposes for developing students’ learning of the subject matter studied. Further recommendations drawn from this study are discussed as well. 相似文献

This study aimed to explore the effect of a mindfulness-based curriculum designed especially for preschoolers on facets of executive functions. Fifty-one preschoolers were randomly assigned to either a mindfulness and kindness curriculum (MC) or an active control dialogic reading program (DR). A battery of behavioral and neurophysiological tests was used to tap into facets of executive control (inhibition, shifting). Electroencephalography data were acquired during the attentional network task (ANT). Relative to DR, children in the MC group exhibited a reduced difference in the N200 Event related potentials (ERP) amplitudes for the congruent versus incongruent conditions during the ANT paradigm representing inhibition and shifting abilities. On the behavioral tasks, both groups improved on executive functions (EF) but on different facets; MC group showed increased inhibition and the DR group demonstrated significantly greater shifting abilities. The results highlight the sensitivity of electrophysiological data to detect subtle cognitive changes. The understanding of how mindfulness-based interventions in preschoolers affect facets of executive functions can enable further refinement and maximization of the benefits of these interventions for this age group. 相似文献

This paper discusses the concept of the network organisation in relation to the technologised university. Drawing upon the early findings of a study that examines the impact of information and communication technologies (ICTs) on both organisational and teaching and learning issues in five Australian universities, the authors discuss the way in which discourses of network technology have become articulated to a range of at times paradoxical agendas within higher education. The introduction of new technologies into organisations tends to be portrayed in either transformative or oppressive terms. The complexity of the university experience foregrounds the important role played by pre‐existing organisational practices and narratives in determining the uses and meanings of ICTs in the organisational setting. These observations place into question the notion that the network organisation is a single coherent entity driven by a particular technological logic. Instead, it suggests that network technologies are socially embedded and therefore highly variable in their expression. 相似文献

Recent research has found that sensitivity to linguistic stress is related to phonological awareness and reading development. This study investigated the roles of two types of linguistic stress sensitivity (lexical and metrical stress) in the phonological awareness and reading development of young children. Forty‐five kindergarten children were tested on a battery of tasks that examined linguistic stress sensitivity and early reading ability. Results indicated that lexical stress, but not metrical stress sensitivity, is significantly related to phonological awareness and early reading ability. However, lexical stress is not able to predict unique variance in early reading ability once phonological awareness is controlled for. The relationships of both lexical and metrical stress sensitivity with phonological awareness and early reading development are discussed. 相似文献

This article reports on an exploratory study of quantitative data use situated in families’ management routines while taking care of a child with Type 1 diabetes (T1D). T1D treatment requires frequent measurement and recording of numerical data about blood sugar concentration, nutritional intake, and insulin dosage at the child’s home, at school, and at other activities. We analyze coordination work between family members and others involved in the care of children with T1D using the lens of distributed cognition, and we introduce the notion of a data catchment to refer to the pathways of data flow and information storage within and between multiple agents and spaces. Interviews and observations reveal three main features of storage and use in data catchments: First, there is a great variability in how data move and are retained to enable communication between family members and others. Second, families tended to focus more on individual data points and less on aggregate readings despite some indications of ability to narrate through aggregate readings. Third, families engage in recurrent conversations and sometimes use novel artifacts to make numerical values meaningful to children with T1D. Implications for understanding this space of practice as constituting a data catchment are discussed. 相似文献

This study took place during the first 2 years of a partnership between three cooperating elementary schools and a college of education. The purpose of the interpretive phenomenological study was to learn from cooperating teachers, student-teachers and college instructors about the transitions that accompanied the change in the culture of schooling they experienced through the newly established partnership, and to attempt to understand their experiences through their explanations of the transitions they identified. On the basis of the data analysis, we identified seven transitions experienced by the participants: From discrete processes to parallel, open processes. From individual work to collaboration. From seeing the other as an object to seeing the other as a critical friend. From leading to responding. From the conception of knowledge as an object to the conception of knowledge as a process. From viewing learning as a linear process to viewing it as a spiral process. From viewing their work environment as a closed system to viewing it as an open system. In this paper, we describe and provide examples of each of these transitions and show how they are interrelated and how each one is both a cause and an effect of the others. These findings increased our knowledge about how the school and college altered each others consciousness. 相似文献

What does it mean to be an ethical businessperson, and how does an ethical businessperson create, locate, organize, and evaluate business information? Critical business information literacy (CBIL) is the application of social justice to business information literacy. This article seeks to define, discuss, and realize CBIL by tracing the literatures of critical librarianship, critical management, and corporate social responsibility. To establish best practices, the authors drew upon applications of CBIL at four institutions of different size, geography, and scale. The intent is to provide spaces and foundations for further CBIL application and discussion. 相似文献
