The Analysis of Purposes of Science Teacher Candidates in Using Social Media
No full textProblem Statement: With the Internet becoming an inseperable part of our lives, the role of social media in daily life is rapidly increasing with each passing day. In this respect, it is important to identify the purposes of teacher candidates in using social media tools that rapidly improve and become widespread in teacher training institutions. Purpose of the Study: In this study, it is intended to identify the variables by which the purposes of science teacher candidates in using social media vary and their opinions about the use of social media in education. Methodology: For this purpose, a scale on the use of social media by teacher candidates has been applied to a sample group of 255 people. The data was evaluated quantitatively with SPSS 17.00 software. In order to identify the views of science teacher candidates on the use of social media in education, five open-ended questions were asked to five people who were randomly selected from the sample group. Findings and interpretation: The research results show that the purposes of science teacher candidates in using social media vary according to demographic characteristics (sex, grade level, family income) and to variables related to Internet usage (frequency of Internet usage, the time spent on the Internet, blog ownership, the purpose of using the Internet, the frequently used social media tools). It is found that science teaching students generally have a positive attitude towards the use of social media in education. Conclusion and Discussion: It is possible to create educational settings for scientific discussions and for sharing ideas on social media. With the use of these settings in education, a lot of activities that will be time-consuming in the class environment can be carried out on social media and science teaching students can be offered many opportunities and tools such as enjoyable homework assignments, complementary videos etc. For example, after the lesson on the subject of cell is completed in the class environment, a video about the structures forming the cell can be shared with the group on the Facebook and a related discussion can be initiated between students where the teacher can also contribute with comments. Or the followers of the teacher can share the stages of an experiment on Twitter and everybody can contribute to the design of a new experiment
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
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
The examination of primary school students' attitudes toward science course and experiments in terms of some variables
No full textThe purpose of this study was to determine the effects of gender, grade and type of school variables on the primary school students' attitudes toward science and technology course and science experiments. The study group is 247 students in 4th, 5th and 6th grades from three public schools and one private school in Istanbul in the semester of 2012-2013. Attitudes toward science and technology course and science experiments scale was used as a data collection instrument within the scope of this study. The scale was developed by Barmby et al (2005) and adapted to Turkish by Kaya and Boyu (2011). The data obtained were analyzed quantitatively using SPSS 16.00. T-test and One Way Anova test, and Kruskal -Wallis test for students' scores for attitudes toward science experiments were employed. In this study, it was found that students' attitudes toward science course didn't differ by gender and school type; however, there was a significant difference in terms of grade in favor of 6th grade. It was also found that students' attitudes toward science experiments didn't differ by gender and grade, however, there was a significant difference in terms of school type in favor of private school. As a result, the difference in favor of private school brings to mind the question how and how often is science taught using experiments in state schools? In this study, it is also recommended that pre-service science teachers should be taught the importance of making science experiments. (C) 2015 The Authors. Published by Elsevier Ltd
