Objects prompt authentic scientific activities among learners in a museum programme     

Marianne Achiam  Leonora Simony  Bent Erik Kramer Lindow 《International Journal of Science Education》2016,38(6):1012-1035

Although the scientific disciplines conduct practical work in different ways, all consider practical work as the essential way of connecting objects and phenomena with ideas and the abstract. Accordingly, practical work is regarded as central to science education as well. We investigate a practical, object-based palaeontology programme at a natural history museum to identify how palaeontological objects prompt scientific activity among upper secondary school students. We first construct a theoretical framework based on an analysis of the programme’s palaeontological content. From this, we build our reference model, which considers the specimens used in the programme, possible palaeontological interpretations of these specimens, and the conditions inherent in the programme. We use the reference model to analyse the activities of programme participants, and illustrate how these activities are palaeontologically authentic. Finally, we discuss our findings, examining the mechanism by which the specimens prompt scientific activities. We also discuss our discipline-based approach, and how it allows us to positively identify participants’ activities as authentic. We conclude by discussing the implications of our findings.  相似文献   

One size still does not fit all in specific learning disability assessment across ethnic groups     

Warner TD  Dede DE  Garvan CW  Conway TW 《Journal of learning disabilities》2002,35(6):500-508

The use of IQ scores and discrepancy formulas for identifying specific learning disabilities (SLD) has been widely discredited by prominent researchers for more than a decade. Nevertheless, the overwhelming majority of state policies still specify the use of discrepancy formulas, including the simple difference method, which is psychometrically inferior to regression-based methods. This study compares the use of a minimum IQ cutoff score and a simple difference method versus a regression-based method for identifying SLD in a sample of African American and European American full-time college students (N = 117). Replicating the findings from previous studies using typically achieving children, typically achieving adults, and school-age children with SLD, this study adds to the chorus of voices criticizing the use of outdated assessment practices that can have deleterious effects for individuals with SLD. The implications for legislative policy are discussed in the context of the historical overrepresentation of African Americans in all special education categories except SLD and the increased access to higher education that students with SLD have gained during the past decade.  相似文献   

Modelling Experiential Knowledge Ethically: An Artefact‐Based Approach to Visually Documenting a Participatory Design Process with Young People     

Marianne McAra 《The International Journal of Art & Design Education》2019,38(3):583-598

This article contributes to the growing debate within art and design education research about the role, legitimacy and accountability of artefacts in the creation and generation of knowledge. I present an artefact‐based approach to visually documenting and disseminating my doctoral practice‐based fieldwork that protected the anonymity of the participants whilst supporting my exploration of the situational, interactional and tacit dimensions of participation. Constructing a three‐dimensional scaled model of the fieldwork setting and using narratives from my field notes, I undertook a cyclical reflective process where I reconstructed critical moments that took place. This was used as both a tool for communicating my participatory design educational practice and for evaluating my findings with the participants. By sharing this sense‐making process, I offer an ethical means of visually documenting fieldwork when working in sensitive contexts and with vulnerable participants, setting out the dual role this design artefact played as both a producer and carrier of experiential knowledge.  相似文献   

Keywords and vocabulary acquisition: Some words of caution about words of assistance     

Craig W. Johnson  Marianne Adams  Roger Bruning 《Educational technology research and development : ETR & D》1985,33(2):125-138

Consistent results of two experiments with relatively technical, native language vocabulary, showed that effectiveness of keyword methods depended upon whether meanings of words to be learned were abstract or concrete and whether comprehension was assessed immediately or after a delay. Keywords bearing acoustical similarities to vocabulary items whose meanings were presented as sentences consistently facilitated students’ retention of the meanings of concrete items on immediate posttests. However, in contrast to recent research on foreign language vocabulary having simpler definitions, these experiments showed that it may be difficult to use the keyword method to aid long-term retention with moderately complex. abstract, native language vocabulary. Parts of this study, which was partially supported by the Kansas State University Bureau of General Research, were presented at the Annual Meeting of the American Educational Research Association, Boston, 1980.  相似文献   

A randomized controlled trial of a home-visiting intervention aimed at preventing relationship problems in depressed mothers and their infants   总被引：1，自引：0，他引：1  

van Doesum KT  Riksen-Walraven JM  Hosman CM  Hoefnagels C 《Child development》2008,79(3):547-561

This study examined the effect of a mother–baby intervention on the quality of mother–child interaction, infant–mother attachment security, and infant socioemotional functioning in a group of depressed mothers with infants aged 1–12 months. A randomized controlled trial compared an experimental group ( n = 35) receiving the intervention (8–10 home visits) with a control group ( n = 36) receiving parenting support by telephone. There were assessments pre, post, and follow-up after 6 months. The intervention had positive effects on the quality of mother–infant interaction. Infants in the experimental group had higher scores for attachment security and for one aspect of socioemotional functioning, namely, competence. The intervention proved successful in preventing deterioration of the quality of mother–child interaction.  相似文献

Test Takers and the Validity of Score Interpretations     

Rebecca J. Kopriva  Martha L. Thurlow  Marianne Perie  Sheryl S. Lazarus  Amy Clark 《教育心理学家》2016,51(1):108-128

This article argues that test takers are as integral to determining validity of test scores as defining target content and conditioning inferences on test use. A principled sustained attention to how students interact with assessment opportunities is essential, as is a principled sustained evaluation of evidence confirming the validity or calling into question the inferences for individual students. Three innovative assessment systems are highlighted to illustrate where and how the developers might handle diverse test taker needs and learning characteristics. ONPAR measures challenging content using multisemiotic methods and novel item types, designing items to handle multiple profiles so they are accessible for most students. Dynamic Learning Maps has built an innovative network of learning maps, and multiple pathways designed to model how diverse students acquire knowledge. To support their assessments, the National Center and State Collaborative has built an exemplary web of educator resources such as content modules and guides in order to support differentiated learning.  相似文献   

Developing citizens and communities through youth environmental action     

Tania M. Schusler  Marianne E. Krasny  Scott J. Peters  Daniel J. Decker 《Environmental Education Research》2009,15(1):111-127

Although several studies have examined learning outcomes of environmental action experiences for youth, little is known about the aims motivating practitioners to involve youth in action creating positive environmental and social change, nor how practitioners perceive success. This research explored through phenomenological interviews practitioners’ purposes for using an environmental action approach. Practitioners in this inquiry, who engaged youth in action addressing a range of environmental issues in varied programmatic and community contexts in the US, expressed multifaceted aims motivating their educational practice. Interpretation of practitioners’ stories with respect to their purposes and perceptions of success contributed to a conceptual framework relating environmental action to the development of citizens and sustainable communities. Whereas others have described the stages and learning outcomes of environmental action, this inquiry illustrates the potential of environmental action for concurrently realizing individual and community level impacts.  相似文献   

Identifying high-quality centre-based childcare using quantitative data-sets: what the numbers do and don't tell us     

Marianne Fenech  Naomi Sweller  Linda Harrison 《International Journal of Early Years Education》2010,18(4):283-296

Quantitative approaches to defining and measuring quality in early childhood education and care (ECEC) have provided a key platform for policy development. Yet their strengths and limitations as informants of high-quality ECEC have not been tested. In this study we examine two sources of quantitative data collected over a five-year period for 74 long day care centres: (1) the Early Childhood Environment Rating Scale-Revised and Infant-Toddler Environment Rating Scale instruments which are well-established observational measures; and (2) Australia's nationally administered Quality Improvement and Accreditation System which involves a self-study and validation process. Correspondence over time and across measures was more consistent for the centres identified as providing lower quality ECEC. Variability in ratings of quality was more evident in lower quality centres, whereas high-quality centres showed less variability over time. High quality, however, was less consistently identified across measures. Discussion focuses on the strengths and limitations of these measures of quality, and the implications these have for policy development and future research.  相似文献   

The “Species” Concept as a Gateway to Nature of Science     

Jorun Nyléhn  Marianne Ødegaard 《Science & Education》2018,27(7-8):685-714

The nature of science (NOS) is a primary goal in school science. Most teachers are not well-prepared for teaching NOS, but a sophisticated and in-depth understanding of NOS is necessary for effective teaching. Some authors emphasize the need for teaching NOS in context. Species, a central concept in biology, is proposed in this article as a concrete example of a means for achieving increased understanding of NOS. Although species are commonly presented in textbooks as fixed entities with a single definition, the concept of species is a highly discussed one in the science and the philosophy of biology. A multitude of species concepts exist, reflecting both the views and interests of researchers and their utility in different organism groups. The present study serves to address the following questions: How do textbooks in Norwegian primary and lower secondary schools present the concept of species? Can inquiries into the concept of “species” serve to highlight aspects of NOS? A review of the available literature on species and species concepts in school is also performed. In the schoolbooks, the biological species concept is commonly used as the main definition, whereas the morphological species concept is represented by additional remarks of similarity. The potential and pitfalls of using the species concept for teaching NOS are discussed, with NOS being discussed both as a family resemblance concept and as a consensus list. Teacher education is proposed as a starting point for inducing a more sophisticated view of biology into schools.  相似文献
