Examples of groups in abstract Algebra Course Books
No full textThis study has been conducted with the aim to examine the examples of Abelian and non-Abelian groups given in the abstract algebra course books in the university level. The non-examples of Abelian groups serve as examples of non-Abelian groups. Examples with solutions in the course books are trusted by the students and hence miscellaneous of those are required to clarify the subject in enough detail. The results of the current study show that the examples of Abelian groups are about the same among three course books, including number sets only with known operations. The examples of non-Abelian groups are rare in comparison and encapsulate the nonnumeric sets which are novel to students. The current study shows the mentioned examples are not sufficiently examined in the course books. Suggestions for the book writers are given in the study. Mainly it is suggested that more and various examples of Abelian and especially non-Abelian groups should be included in the course books
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
University students’ self-efficacy and achievement in derivative concept
No full textThe purpose of the current study was to explore the relationship between self-efficacy and achievement in the derivative concept in university level. University students from education, engineering and science faculties attended the study. 1660 students’ data were gathered and the study has demonstrated that the there is a moderate and positive relationship between university students’ self-efficacy levels and their achievement in derivative concept. It is suggested that university level students’ self-efficacy levels be addressed when considering their achievement in the derivative concept
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
Enhancing Engineering Students\u27 Mathematics Learning Through Digitised Effective Feedback
Get PDFThis practice paper explores the impact of effective digitised feedback on engineering students\u27 mathematics learning in the digital environment. By using a schematic framework, an online repository will be developed to provide effective feedback to the first-year students taking mathematics courses. The repository takes into account calculus topics and focuses on providing guidance to students who give incorrect answers to questions by incorporating sub-questions based on Polya\u27s heuristics. The sub-questions aim to motivate students to draw on simpler connections and stimulate learning by encouraging students to check their answers and reflect on their initial responses. This study is currently an ongoing project in the Netherlands and aims to improve outcomes in calculus courses and provide a database of online exercises for digital exams, which will save teachers time, in long term
