Cross-curricular collaboration in teaching social aspects of genetics
No full textScience teachers can lack pedagogic skill and confidence in handling multi-faceted socio-scientific issues. This project has explored the development, implementation and evaluation of a ‘cross-curricular’ day as a suitable vehicle in 8 different schools for both engaging 14-16 year old pupils in active consideration of social aspects of genetics and enabling science and humanities teachers to collaborate in planning and delivery. The cross-curricular research team planned a programme of activities, involving volunteer teams of teachers in development. Pupils in participating schools generally found the day stimulating, increasing their understanding of genetics and appreciation of social aspects. However, implementation showed that some teachers missed important learning opportunities. The paper explores the nature and implications of cross-curricular collaboration for increasing pupils’ engagement with social and ethical aspects of biomedical science and science teachers’ pedagogic skill
On the ball: particle models for KS3 science
No full textScience is about explanation. It attempts to make sense of the world by constructing models or theories through a creative approach, often referred to as the hypotheticodeductive method. These models or theories are VISUALISATIONS; they are pictures we carry in our heads, often brought about by concrete representations
Designing a professional development programme: a process of change management
No full textThis paper reports the evaluation of a three-phase model of developing CPD, in which the developers worked in partnership with teachers to design a package for promoting accomplished science teaching across six key domains of practice (eg assessment for learning, argumentation). The data comprise interviews with developers at the end of each phase (22 in total) and with teachers at the end of phases 2 and 3 (11 interviews). The analytical framework was based on a change transition model consisting of 4 interlocking layers: trigger, vision, conversion and maintenance. Using issues around compiling portfolios of evidence, we track the evolution of a CPD package from inception to completion, highlighting good practice as well as potential pitfalls. The iterative nature of the development of the CPD is shown to have real value. Whilst the potential for evidence-based CPD is high, without considerable justification and support there is a danger that tasks such as compilation of a portfolio might become barriers to participation rather than key parts of the process
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
