E-learning with WebTeach - a prototype system for exam delivery and on-line teaching
No full textThe WebTeach project has been started in 1999 as a prototype to
handle our exams. At this moment it consists of three main components: WebCheck, handling exam sessions through a web interface,
WebWrite, web based tool for teaching on-line, and WebTest, for the
generation and correction of multiple-choice quizzes.
The system, described in the following pages, is now used by more
than 70 teachers and handles 180 subjects, 800 exams and 5500 students. Despite these figures, the project keeps its prototypical flavor
and it’s improved every day following teachers’ and students’ suggestions.
The system is developed using only free software. It’s possible to
cooperate to its development, adapt it to special needs and use it in
other frameworks.
The following extensions are planned:
• Usage of SMS messages for teacher-student communication,
to be added to the e-mail messages already used.
• Development of a system to collect tests’ results through optical reader/SMS/email/web and development of a graphic
interface for quiz generation.
• Management of class reservation/usage.
• Development of a system which will generate/configure automatically a course, given a simple specification of: -
pre/post requisites of each lesson, - the target knowledge
produced by the course, - the initial/current knowledge of
the single student.
The WebWrite system has been chosen also to teach on-line to jailed students through the “Polo Universitario Penitenziario”
WEBTEACH: WEB TOOLS FOR TEACHERS AND STUDENTS
Full text linkThe authors present the WebTeach system, currently used at the Engineering Faculty, University of Florence, Italy. The system is composed of three parts: WebCheck, a web database interface for test management; WebTest, a multiple-choice quiz generation system; and WebWrite, a collaborative Web publishing tool. WebCheck is used for managing subscriptions to tests and publication of results. It allows teachers to organize exam sessions and students to consult the results of their tests by a web interface. Most of tests are generated using WebTest, which is a suite of Perl libraries and front-end applications for the generation and automatic evaluation of multiple-choice quizzes. Web Write is an implementation of the TWiki system, which appears as a web site where all pages can be edited using a simple syntax, resembling e-mail text. WebWrite is used for publishing didactic material and will become the generic interface-managing tool of the WebTeach system. This system is also used for teaching to jailed students
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
WebTeach in practice: the entrance test to the Engineering faculty in Florence
No full textWe present the WebTeach project, formed by a web inter face to database for test management, a wiki site for the diffusion of teaching material and student forums, and a suite for the generation of multiple-choice mathematical quiz with automatic elaboration of forms. This system has been massively tested for the entrance test to the Engineer ing Faculty of the University of Florence, Italy
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
