EXTRA-CURRICULAR SCIENCE LABS FOR GIFTED STUDENTS
Get PDFIn the past couple of years numerous extra-curricular science laboratories (‘school labs’) have been established, their main objective being to attract school students to science and technology. The DLR_School_Lab Oberpfaffenhofen, operated by Germany's national research center for aeronautics and space, DLR, is a typical example for such a science lab. Apart from hands-on experiments offered for students, one of its key activities is the education of teachers.
In this paper the basic concept of an extra-curricular science lab is presented, as well as the special concept of the DLR_School_Lab and its strong ties to state-of-the-art-aerospace research and technology. The lab’s great expertise from numerous high-level enrichment projects for highly talented secondary school students is described. Furthermore, its teacher education concept and capabilities with respect to gifted education is demonstrated. Finally, results from internal and external evaluations are presented which indicate the successful operation of extra-curricular science labs
Inner Landscapes: Transformative Learning Experiences of Canadian Education Interns in Greece
No full textThis exploratory study uses transformative learning theory as a lens to interpret and understand the challenges and successes experienced by education students who elect to teach or intern abroad. Transformative learning is a deeper-level learning that challenges learners to understand themselves and their world in new, more nuanced ways. We explore frames of teaching and learning from multiple lenses. Elements of the educational internship experience that emerged from students who participated in this study include initial apprehension, disbelief, and even fear; a disorienting dilemma or incongruent experience within the new school cultural context; a re-evaluation of their frames of reference, and a final emergence of more integrative, inclusive senses of self as “teacher” and “learner.” Transformative learning theory can serve both as a conceptual framework for understanding the experiences of students and as a means of suggesting ways in which educational outcomes can be better designed with a transformative intent in mind. We then present implications for teaching and learning and suggestions for future studies.

Services for preschool children with special needs in state day care centres in Greece : issues and national policy directions
Get PDFIn 1984, integration of children ages 6-12 years with special needs
was legislated in Greece with the introduction of the resource room model of
service delivery at the primary school level. However, this model did not extend
into the preschool years. There is increasing empirical support for the importance
of early intervention for children at risk. A survey was conducted in 55 state-run,
day care centres in Greater Athens to examine current acceptance rates, preferred
service delivery models and projected needs. The survey found that preschoolers
with special needs are grossly under-served. Although it is generally accepted that
10% of the population is challenged, only 2.5% of the total enrollment in the
surveyed day care centres had special needs. Despite the lack of supports, almost
half of these centres accepted children with mild to moderate special needs
(primarily language problems, behaviour challenges, and developmental delays).
The most preferred model of service delivery identified by centre directors was
total integration with support from a special needs teacher. Additional issues and
concerns voiced by directors are addressed and national policy recommendations
are made.peer-reviewe
Individual Variables, Literacy History, and ESL Progress Among Kurdish and Bosnian Immigrants
No full textThis study examines the relationship between individual variables and ESL progress among nine Kurdish and seven Bosnian immigrants. All participants are adult refugees who arrived in Canada with virtually no English. Significant correlations are found between the dependent variables of oral and written progress and the independent variables of literacy level, years of schooling, and ethnicity. Contingency, text quality, and text quantity are also examined. Although the number of participants is small and the number of variables examined is large, it is hypothesized that in 18-21 months high literates will progress from low beginner to advanced, semi-literates from pre-beginner to low intermediate, and pre-literates from pre-beginner to low beginner. The article concludes with implications for ESL programming and future research
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
