CHALLENGES OF TEACHING BASIC SCIENCE AND TECHNOLOGY (BST) IN ANAMBRA STATE PUBLIC SCHOOLS
Get PDFThis study investigated the challenges constraining effective teaching of Basic Science and Technology (BST) in the public schools of Anambra state. A research question guided the study which adopted a descriptive survey research design. A sample of six hundred and sixty-one (661) was composed of a population of six thousand six hundred and fifteen (6615) BST teachers in the State. Proportionate stratified random sampling technique was used. A 21-item, four-point rating Questionnaire, developed and validated by the researcher, was used for data collection. The contents of the instrument were clustered into four sections namely: Curricular Materials, Instructional Materials, Human Resources and Teaching Methodology. The instrument, with a reliability index of 0.75, was adjudged reliable and usable for the study. Data were analyzed using simple mean ratings. Results indicated among others that: BST curricula materials were adequately provided to schools (mean=2.99), instructional materials are inadequately supplied (mean=2.31), Relevant human resource was in short supply (mean=1.93) as well as Methodological shortcomings (mean=2.28). Some recommendations including that: BST laboratories and equipment should be provided in schools to complement the resources available from immediate school environment; Training and recruitment of specialist BST teachers and retraining of available teachers in science disciplines, is a sine qua non towards realizing the goals of teaching BST; Regular refresher courses are necessary to update BST teachers' skills, knowledge of the subject matter and teaching methodology, were mad
IMPACT OF INDIVIDUALIZED LEARNING STRATEGY ON STUDENTS’ INTEREST IN DATA PROCESSING IN NNEWI EDUCATION ZONE OF ANAMBRA STATE
No full textThe study examined how data processing students’ interest could be improved through the use of individualized learning strategy in Nnewi Education Zone of Anambra State, Nigeria. The study adopted a quasi-experimental design, specifically the pretest posttest non-equivalent control group research design. Two research questions and two null hypotheses guided the study. A two-stage sampling procedure were used to sample 38 public co-educational secondary schools out of 50 public schools in Nnewi education zone of Anambra State. A simple random sampling technique (balloting without replacement) were used to select 6 public co-educational secondary schools. Intact classes from the 6 schools were used for the study. The instrument used for data collection were an adapted interest scale questionnaire. The reliability of the interest scale tagged computer maintenance ethics and human issues questionnaire (CMEQAHI) were determined using Cronbach Alpha method with an index value of 0.71. The two groups were taught six lessons on the theme computer maintenance ethics using individualized learning strategy (ILS) and lecture method (LM) respectively. Data were collected by administering CMEQAHI on the participants as pre-test and post-test. Data obtained were analyzed using mean, standard deviation and two-way Analysis of Covariance. The findings revealed among others that there is a significant difference in the mean interest rating scores of students exposed to ILS and LM in favour of the former group. Based on the findings, the study recommended that individualized learning strategy should be incorporated in the curriculum as a teaching strategy in teaching data processing in the classroom since it encourages self-development
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
