Students’ Views toward the Usage of Weblogs for Educational Purposes in Nigerian Tertiary Institutions
Get PDFThe aim of this paper was to evaluate students’ views toward the usage of weblogs for educational purposes in Ondo state tertiary institutions. Three research questions were designed to guide the study. The population consisted of all undergraduates in three selected tertiary institutions in Ondo state. The sample of the study consisted of 358 respondents who were selected using convenience and purposive sampling techniques. A self-structured questionnaire was used to collect data. The result of the findings revealed that students are aware of the usage of weblogs for educational purposes. The findings revealed that students show a positive perception toward the weblog. It was also revealed that Blogs help to provide solutions to Group assignments through enhanced interaction, promote reflective learning, and enhance interaction between teachers and students. Lastly, the results of the study revealed that constraints such as inadequate electricity, bad internet facility, lack of mobile phones and personal computers, lack of relevant software, and insufficient knowledge are the constraints toward the usage of weblogs. Based on the findings of this study, it was recommended among other things that administrators of tertiary institutions should create an enabling environment for intellectual exchange, aligning with tertiary institutions' curriculum to promote the use of weblogs for educational purposes. It was also recommended that Governments should install robust and reliable Internet (Wi-Fi) facilities through the Department of ICT Directorate in the tertiary institutions
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
An Appraisal of Educational Technology Usage in Secondary Schools in Ondo State (Nigeria)
No full textInternational audienceThis study examined and appraised the use of Educational Technology in secondary schools in Ondo State South West, Nigeria. The study investigated the level of availability of Educational Technology facilities in schools, attitude of teachers toward educational technology, the perceived benefits of using Educational Technology, the problems facing the use of Educational Technology in secondary schools and Application of Educational Technology in schools by teachers. The descriptive survey design was used for the study. The population consisted of all the teachers and principals of the secondary schools in Ondo State. The sample consists of 400 teachers and 40 principals randomly selected from the secondary schools in Ondo State. A self designed questionnaire tagged Educational Technology and Secondary Schools (ETSS) was used to collect the data for the study. Data collected for the study were analyzed using frequency count, percentage scores, mean and charts. The study revealed that Educational Technology facilities were lacking in schools and teachers and students were to a little extent exposed to the use of Educational Technology. Moreover, the study revealed the perceived benefits of using Educational Technology in schools which include making teaching-learning interesting; helping the distance learning program; Educational technology provide for individual differences; Educational technology makes teaching efficient and effective. However, despite these perceived benefits, the study also revealed some of the challenges facing Educational technology in secondary schools as: Epileptic supply of electricity: misconception of right concept of educational technology; Shortage of specialist in educational technology; inadequate facilities to support full application of educational technology and lack of fund. It was therefore recommended that government should increase the funding of the education sector. There should also be periodic training for teachers on educational technology skills acquisition
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
The Challenges Toward Implementation of Information and Communication Technology (ICT) in Secondary Schools in Ondo State, Nigeria
No full textInternational audienceThe study investigated the Challenges of Information and Communication Technology (ICT) in secondary schools in Ondo state. It sought to find out the level of access to ICT among secondary school teachers and students. Also the study investigated the level of utilization of ICT for instructional purposes and the attitude of teachers and students towards ICT utilization of ICT in secondary schools. The study adopted the descriptive survey design. The sample for the study consisted of 450 teachers randomly selected from two hundred and ninety six (296) secondary schools in the eighteen Local Government Areas of Ondo State. A combination of multistage, stratified and simple random sampling technique was used in selecting the sample. A questionnaire titled "Challenges of information and communication technology for secondary schools teachers (CICTSST)" was designed and validated. The data obtained were analyzed using frequency counts, percentages, mean and bar chart. The result of the findings showed that: ICT facilities are not available in schools. Majority of the teachers and students do not have access to ICT. There are significant factors affecting the utilization of ICT for instructional purposes. The study also revealed that teachers show positive attitude toward utilization of ICT in teaching and learning
