EFFECTS OF EXPOSITORY ADVANCE COGNITIVE ORGANIZER ON SENIOR SECONDARY SCHOOL STUDENTS’ ACHIEVEMENT IN MATHEMATICS IN ENUGU EAST L. G. A. OF ENUGU STATE
No full textThe consistent poor achievement of students in Mathematics has continued to generate reactions from both the government and stakeholders in education sector. Against this background, several efforts have been made to find solutions to the problem. It is on this note that this study investigated effect of expository advance cognitive organizer on senior secondary school students’ achievement in Mathematics in Enugu East L. G. A. Enugu State, Nigeria. The study has two research questions and three research hypotheses. It adopted a non-equivalent control group quasi-experimental research design. The sample size for this study was 157 which was made up 59 males and 98 females. Out of the 10 public secondary schools in Enugu East L.G.A., five are co-educational schools and two schools were randomly chosen from the five schools. In each of the two schools sampled, two intact classes were randomly selected and used for the study. The instrument used for data collection was Circle Geometry Achievement Test (CGAT). The reliability coefficient of the CGAT was determined to be 0.75 using K-R 20 formula. The instrument was administered to the students before the treatment and after the treatment. The research questions were answered with mean and standard deviation while the hypotheses were tested with ANCOVA probability level of .05. After the data analysis, the following findings were made: students taught circle geometry with expository advance cognitive organizer achieved better than the students taught with traditional method; there is no significant difference between the mean scores of male and female students with expository advance cognitive organizer. Based on the findings, the researcher recommended that, in addition to organizing conferences for in-service Mathematics teachers; seminars and workshops should be organized by the school board for Mathematics teachers on how to use advance cognitive organizers in teaching Mathematic
HUMAN RIGHTS AND DEMOCRATIC PEDAGOGY AS AN INNOVATIVE APPROACH TO GIVING SECONDARY SCHOOL STUDENTS A TRUE VOICE IN THE TEACHING AND LEARNING OF MATHEMATICS
No full textThe study of Mathematics in secondary schools is as old as the history of education in Nigeria. However, as shown by the students\u27 poor performance, the study is not yet as expected. Several efforts have been made by several concerned individuals and groups, both governmental and non-governmental agencies, to change the narrative with little success. In all these efforts, little has been said about students\u27 knowledge of their human rights and learning in a democratic environment. On this note, this work proposed an innovative approach to teaching and learning, emphasizing Mathematics teaching and learning in secondary schools. The approach is named human rights and democratic pedagogy. This approach highlights the importance of students actively engaging as young citizens. It encourages them to learn about and understand their human rights and value and respect those rights. Through classroom lessons and hands-on experiences in their school community, students gain the confidence to exercise their rights meaningfully. The approach is based on a constructivist approach to learning. It can keep teaching and learning afloat during a pandemic since students are the major players in its usage as a teaching strategy. The three components of the pedagogy (teaching "about," "for," and "through" democracy) were extolled. The teachers\u27 roles and the expectations of the students, if the pedagogy is appropriately utilized, were also treated. The study also recommended how to institutionalize this new approach to teaching and learning Mathematics or any other school subject
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
EDUCATIONAL LEADERSHIP CHANGE IN POLICY AND GOVERNANCE: A PANACEA FOR SCHOOL INITIATIVES IN NIGERIA
No full textIn the Nigerian education system, organizational change is frequently misconstrued as being driven by individual or group preferences. This article aims to delve into various pieces of literature to explore how change leadership in policies and governance can be effectively implemented in schools to foster innovation. Employing a meta-framework design approach, the article thoroughly reviews change leadership domains. A synthesis of peer-reviewed journals is presented to elucidate the nexus between leadership philosophy, change, and innovations within Nigerian educational institutions. This examination is conducted through the dual lenses of process and content. The article argues that successful change leadership in school settings necessitates several key steps: identifying the need for change, engaging stakeholders to acknowledge this need, structuring the change process, fostering stakeholder commitment, implementing and sustaining change through robust planning and oversight, and nurturing individual and organizational capabilities to enable problem-solving and solution generation. Moreover, it challenges the notion that change is solely a top-down endeavour, asserting that leadership is predominantly a social practice or process rather than merely a charismatic display
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
