he Challenges of Teaching Good Information Processing to Learning Disabled Students     

John G. Borkowski  Wolfgang Schneider  Michael Pressley 《International Journal of Disability, Development & Education》1989,36(3):169-185

A MODEL of good information processing is sketched, describing how metacognitive knowledge influences strategy selection and use. Three factors pose particular problems for learning disabled students as they attempt to acquire metacognitive knowledge and to use study strategies productively: neurological impairments; deficiencies in general world knowledge; and negative beliefs, attitudes, and styles that limit self‐efficacy. Creating an educational atmosphere that explicitly builds conceptual (domain‐specific) knowledge and teaches positive beliefs about learning potential is essential in promoting metacognitively‐oriented instruction.  相似文献   

Skill Acquisition and Reflection‐based Decision Making in a Teaching Laboratory: an evaluative study     

Hans Gerhard Klinzing 《欧洲师范教育杂志》1988,11(2):167-175

This paper continues the tradition of research, development and evaluation of teaching laboratories, and, at the same time, extends earlier research in two directions: by placing more emphasis on the improvement of a reflection‐based decision‐making ability in becoming a teacher (beyond effective skill acquisition), and by concentrating on the improvement of presentation skills, an area neglected in teacher training. Based on research on teaching and teacher training, a training program was developed for enhancing the trainees’ nonverbal expressiveness in presentations that, by fostering reflection‐based decision making through experimenting with presentation skills in a laboratory with feedback and discussions, also improves the clarity, interest and social climate of presentations. The evaluation of the most recent Version of this program reveals that significant gains could be achieved not only in nonverbal expressiveness as an indicator for successful skill acquisition, but also in the global aspects of successful lecturing indicating that the program was also effective for the improvement of the trainees’ reflection‐based decision making.  相似文献   

Sensory Processing in Rhesus Monkeys: Developmental Continuity,Prenatal Treatment,and Genetic Influences          下载免费PDF全文

Mary L. Schneider  Colleen F. Moore  Miriam Adkins  Christina S. Barr  Julie A. Larson  Leslie M. Resch  Andrew Roberts 《Child development》2017,88(1):183-197

Neonatal sensory processing (tactile and vestibular function) was tested in 78 rhesus macaques from two experiments. At ages 4–5 years, striatal dopamine D₂ receptor binding was examined using positron emission tomography. At ages 5–7 years, adult sensory processing was assessed. Findings were: (a) prenatal stress exposure yielded less optimal neonatal sensory processing; (b) animals carrying the short rh5‐HTTLPR allele had less optimal neonatal sensory scores than monkeys homozygous for the long allele; (c) neonatal sensory processing was significantly related to striatal D₂ receptor binding for carriers of the short allele, but not for animals homozygous for the long allele; and (d) there was moderate developmental continuity in sensory processing from the neonatal period to adulthood.  相似文献   

Innovative Work Behaviour in Vocational Colleges: Understanding How and Why Innovations Are Developed     

Gerhard Messmann  Regina H. Mulder 《Vocations and Learning》2011,4(1):63-84

In workplaces, innovative products and processes are required to address emerging problems and challenges. Therefore, understanding of employees’ innovative work behaviour, including the generation, promotion, and realisation of ideas as components of this behaviour is important. In particular, what fosters innovation development and what triggers these activities is important for its promotion and adoption in contemporary workplaces. To investigate how and why innovations at work are developed and enacted, an explorative study comprising structured interviews with vocational teachers in the German vocational system was conducted. The teachers reported on activities they undertook during the development of a specific innovation. Furthermore, they provided information on factors that made this innovation necessary and that they were activated by. The study indicates that even when opportunities for innovation development existed in a workplace, the needs and goals of teachers were pivotal for these opportunities to be recognised and teachers’ innovative work behaviour to be triggered. By analysing vocational teachers’ work activities, we found that the development of innovations was a complex, iterative and primarily social process. By encouraging teachers to act on opportunities for change and by establishing a collaborative structure at schools, innovation development can be facilitated. We also found that throughout the development of an innovation, reflection played an important role. If the importance of reflective activities is acknowledged by workplaces such as these participants’ vocational schools, this not only fosters innovations but also the teachers’ professional development.  相似文献   

p2pDating: Real life inspired semantic overlay networks for Web search     

Josiane Xavier Parreira  Sebastian Michel  Gerhard Weikum 《Information processing & management》2007

We consider a network of autonomous peers forming a logically global but physically distributed search engine, where every peer has its own local collection generated by independently crawling the Web. A challenging task in such systems is to efficiently route user queries to peers that can deliver high quality results and be able to rank these returned results, thus satisfying the users’ information need. However, the problem inherent with this scenario is selecting a few promising peers out of an a priori unlimited number of peers. In recent research a rather strict notion of semantic overlay networks has been established. In most approaches, peers are connected to other peers based on a rigid semantic profile by clustering them based on their contents. In contrast, our strategy follows the spirit of peer autonomy and creates semantic overlay networks based on the notion of “peer-to-peer dating”. Peers are free to decide which connections they create and which they want to avoid based on various usefulness estimators. The proposed techniques can be easily integrated into existing systems as they require only small additional bandwidth consumption as most messages can be piggybacked onto established communication. We show how we can greatly benefit from these additional semantic relations during query routing in search engines, such as Minerva, and in the JXP algorithm, which computes the PageRank authority measure in a completely decentralized manner.  相似文献   

Information-system structure by communication-technology concepts: A cybernetic model approach     

Gerhard H. R. Reisig 《Information processing & management》1978,14(6):405-417

Information-systems are classified into two types, termed “Evidence-of Existence” and “Presentation” of information. The objective of the evidence-type system lies in the domain of documentation and retrieval of information. The structure of this system-type is developed, with application of cybernetic concepts, as an isomorphic model in analogy to the system-structure of communication technology. The latter postulates three criteria of structuring: (1) Source-Channel-Sink, with input-output characteristics, (2) Filter-type communication-channel, (3) Reversable code. These criteria are applied to the structuring of information-systems of the evidence-of-existence type. For the purpose of two-way communication the information-systems have to be represented by closed-loop models. The selective-retrieval requirements necessitate the system-channel to be a filter of information. These information-filters are implemented by keyword-phrases, being identical with the codewords. They yield a uniquely decodable code which is totally reversible to adequately serve both the documentation and the retrieval of documents. It is proven that hierarchic information-systems, applying categorization or subject-heading objects of information, do not meet the mandatory code-requirements. The inherent coding-deficiencies of hierarchic systems generate intolerable retrieval ambiguities. The same critique applies to the thesaurus concept. The development of a novel species of thesaurus is suggested, realizing a kind of Linnéan encyclopedia of general human knowledge, presenting all relevant interrelations of objects of knowledge. Such thesaurus would provide the much needed support for formulating efficient search queries. Other relevant features of communication technology, like the information-potential, should be isomorphically transformed into information-system models.  相似文献   

Sensory processing disorder in a primate model: evidence from a longitudinal study of prenatal alcohol and prenatal stress effects     

Schneider ML  Moore CF  Gajewski LL  Larson JA  Roberts AD  Converse AK  DeJesus OT 《Child development》2008,79(1):100-113

Disrupted sensory processing, characterized by over- or underresponsiveness to environmental stimuli, has been reported in children with a variety of developmental disabilities. This study examined the effects of prenatal stress and moderate-level prenatal alcohol exposure on tactile sensitivity and its relationship to striatal dopamine system function in thirty-eight 5- to 7-year-old rhesus monkeys. The monkeys were from four experimental conditions: (a) prenatal alcohol exposed, (b) prenatal stress, (c) prenatal alcohol exposed + prenatal stress, and (d) sucrose controls. Increased D(2) receptor binding in the striatum, evaluated using positron emission tomography neuroimaging, was related to increased withdrawal (aversion) responses to repetitive tactile stimuli and reduced habituation across trials. Moreover, prenatal stress significantly increased overall withdrawal responses to repetitive tactile stimulation compared to no prenatal stress.  相似文献   

Von der Hauptschule in die Sekundarstufe II ein aufstiegsbedingter Abstieg     

Edina Schneider 《Zeitschrift für Erziehungswissenschaft》2018,21(6):1187-1203

Efforts to break the link between the school type attended and the qualification awarded are seen as an important step towards more permeability and upward mobility of Germany’s tracked secondary school system. Results from a biographical longitudinal study, which explored the transition from the low-ability school type Hauptschule to upper secondary education in general and vocational Gymnasium (grammar schools) yet show that from the students’ perspective, it is very challenging to take on the transition from lower-level ability to upper-level secondary school types , even though this may be institutionally possible, and desirable from an educational political perspective. For the students, this transition brings along the experience of severe degradation  相似文献   

‘The rules above the bed’: academic language and learning as hospitality     

Dana Chahal  Juana Maria Rodriguez  Britta Schneider 《高等教育研究与发展》2019,38(5):893-906

ABSTRACT

In times of widening participation, Australian universities trade on notions of diversity, framing themselves as hospitable places of access and inclusion. In this space, Academic Language and Learning (ALL) practitioners may be seen as extending the welcome of the university through practices aimed at addressing students’ diverse needs. These include identifying students ‘at-risk’ of failure and attrition, conducting one-to-one appointments, and embedding academic literacies by team-teaching within disciplines. In this paper, we reflect on these practices through the lens of Derrida’s notion of hospitality, drawing on key themes such as the constitutive power relationships of hospitality, the aporia between conditional and unconditional hospitality, and hospitality as an ethics of difference and openness to the ‘arrival of the new’. For each of the explored practices, we problematise the institutionalised framing of ALL practitioners as hosts in benevolent universities providing an unreserved welcome to the student ‘foreigner’. We examine the practice of identifying students-at-risk and question a conditional hospitality that risks closing the door on the unforeseeable that students may bring. Our reflection on the managerially devalued one-to-one appointments highlights hospitality as ethics, with each appointment presenting a crisis of choice in responsibly welcoming student difference. Team-teaching exposes the ambiguity of the ALL practitioner ‘being at-home’ in embedded contexts while presenting the possibility for disrupting established roles and practices. Engaging with Derrida’s hospitality thus allows us to uncover power dynamics shaping the role of ALL practitioners and offers the possibility of ethical responsiveness to student difference and a radical opening to the new.  相似文献

Das Fremdenrechtspaket 2007 führte auch im Bereich des Aufenthalts von Studierenden und Wissenschaftlern zu einschneidenden ?nderungen. Von universit?rer Seite wird h?ufig kritisiert, die neuen – tendenziell restriktiveren – Regelungen beeintr?chtigen die Internationalit?t und Mobilit?t der ?sterreichischen Universit?ten. Der vorliegende Beitrag untersucht den Inhalt der einschl?gigen Regelungen, beleuchtet deren Auslegung durch die Praxis kritisch und zeigt auch aus rechtspolitischer Sicht m?gliche ?nderungsvorschl?ge auf.  相似文献
