Effect of Application of Model for Inclusive and Compulsory Participation Strategy for Teaching and Learning Mathematics on Students’ Learning Outcomes
No full textInclusive and compulsory participation strategy of teaching mathematics is designed to ensure that all the learners and the teacher are involved in the teaching and learning process. A pretest, posttest, quasi-experimental design study was carried out with 275 senior secondary school class two (SSC2) students to test the effectiveness of the model. They were divided into experimental group of 135 students, taught construction and loci using inclusive and compulsory participation strategy and control group comprising 140 students, taught the same topic using conventional strategy. The result showed that the experimental group had a mean score of 87% and standard deviation of 7% as against mean of 53% and standard deviation of 9% obtained by the control group. This give a t-test score of 34.76 which is greater than the critical value of t = 1.96 at 0.05 level of significance, implying that there existed a significant difference in the achievement, in favour of the experimental group with higher mean score. Similarly, the attitude test scores were 73% with standard deviation od 5% for the experimental group while the control group had a mean attitude score of 49% and standard deviation of 6%, giving t-test of 35.95 showing that there is a significant difference in the attitude score of the groups with the experimental group having higher mean attitude score of 73% as against 49% and standard deviation of 5% and 6% respectively obtained by the experimental and control groups. The model and its strategy is highly recommended.  
Evaluation of the Impact of Webinar on Teaching Mathematics to Undergraduate Students
No full textWebinar is an application of video conferencing to communicate with a group of persons and have discussions as if all are in the same place. It is a handy tool for distance learning and educational-based communication. Employing webinars in education has the advantage of helping users achieve their goals in their comfort zones. In this study, a survey of 250 undergraduate students and 50 mathematics teachers on the impact of webinars on the teaching of mathematics was carried out. The students were divided into 50 students majoring in mathematics and 200 students who offered mathematics as a compulsory course. All the teachers were university lecturers currently teaching mathematics in the universities in Rivers State, Nigeria. All the subjects are familiar with the webinar. Fourteen-item Likert Scale questionnaire was used for the study. Data collected were analyzed using a chi-square test at a .05 significance level. The result reveals that webinars are an acceptable medium for teaching mathematics but with reservations. The proviso is that it should be used where one–to–one interaction is impossible. Secondly, the webinar package should be wealthy so that while discussing, it would be easy to understand and waste of resources on data avoided
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
