Analysis of visual representations included in the Organic compound topics in lower-secondary chemistry textbooks
No full textThe submitted bachelor's thesis focuses on the analysis of visual components in the themes subsumed under the thematic area of Organic compounds in lower-secondary-school chemistry textbooks granted with a valid approval clause from The Ministry of Education, Youth and Sports of the Czech Republic. In the first part, the author deals with the theory, validation, evolvement and research of the textbooks. In the other parts, the author achieves the results through set out objectives and methods and offers a final evaluation. The conducted analysis is based on an altered method of Slovenian author N. Zupanc and provides an objective comparison of different textbooks and their selected chapters. The aim of this thesis is comparison of chosen chemistry textbooks from the point of their visuals and transitions between levels representing individual components. The textbooks, which were published after the introduction of the current curriculum, are considered to be processed didactically better - those are the two textbooks published by Nová Škola and Fraus. The differences between these two textbooks are rather on the level of chapters, subchapters and transitions between the visuals more than between the textbooks as a whole. The disparity between the textbooks as a whole is clear when comparing the..
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
Activating Strategies of Managing Students' Learning Process in Chemistry
Get PDFTITLE: Activating Strategies of Managing Students' Learning Process in Chemistry AUTHOR: Št pán Gabriel DEPARTMENT: Department of Chemistry and Chemistry Education VEDOUCÍ PRÁCE: PhDr. Martin Rusek ABSTRACT This thesis is focused on literature-search evaluation of modern methods applied in chemistry education. Firstly, the development of chemistry education from the beginnings of the Czech schooling system until present is briefly described. Further, currently the most widely discussed methods used in Science education eventually Chemistry were defined based on the analysis of scientific literature and other available electronic resources. These methods are briefly characterized; an evaluation of the possibility of their usage in teaching practice in terms of Czech schools is made not only with regards to the educational reality in schools, but also with respect to the law (Framework Educational Programmes). KEYWORDS: Chemistry teaching, modern teaching methods, constructivism, project-based learning, inquiry-based learning, STEM, STEA
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
Elaboration of Learning Problem-Tasks from the Field of Chemistry
Get PDFThis thesis deals with the elaboration of learning problem-tasks related to the Standards for elementary education in the field of Chemistry. The author of this thesis worked on this topic within a project under National Institute for Education. The starting point for creating the tasks, illustrating and concretely expounding the Standards is the concept of science literacy. In this principle in chemistry instruction a broader context and a transfer to everyday life are applied. Learning tasks were created on the base of: science literacy and the results of Czech pupils in its testing, context of standards in Czech curricular system, elements of problem-based learning, types of learning tasks and cognitive parameters. During the elaboration of the tasks a pilot testing of selected learning tasks was realized. The results of the pilot testing were used in further designing more problem-tasks to cover one expected outcome in every topic of Chemistry within the elementary school curriculum. According to the methodology described in this thesis, a material named Methodical comments and tasks to the standards for primary education - Chemistry was created. This material contains a coherent set of learning problem-tasks illustrating two- thirds of the indicators from the standards for elementary education..
