Analysis of difficult concepts in Senior Phase Mathematics baseline assessments: First-year student teachers’ reflections
Full text linkThis paper report on first-year student teachers’ reflections on the difficulty levels of mathematics concepts in the senior phase baseline assessments. This paper emanated after first year student teachers completed the baseline assessments for each of the three grades in the senior phase, Grades 7, 8, and 9. One hundred and sixteen (116) first year mathematics student teachers were included in this study. Data were collected using purposive and convenience sampling methods. This qualitative research adopted a case-study design, using an interpretivist paradigm. Data was collected using an open-ended questionnaire as the research instrument. The questionnaire was designed to determine student teachers’ thoughts about the difficulty levels of concepts of the mathematical content in the baseline assessments. The results of the study revealed that Algebra; Number Pattern; Statistics; Shapes; Geometry; Simplification; Sequences and Series; and Addition and Subtraction of numbers as easy topics to answer, Fractions, Mixed fractions, Factorisation, Probability, and Measurement were topics that were very difficult. The study recommended that teacher educators design instructions that will assist student teachers in constructing senior phase mathematical concepts to improve their understanding of these complex topics in higher education institutions. 
Enhancing Learners\u27 Geometric Thinking Using Dynamic Geometry Computer Software
Full text linkThe appropriate use of dynamic geometry computer software in teaching and learning geometrical concepts is an essential factor of quality mathematics in secondary schools and TVET colleges. The aim of this study is to measure learners\u27 Geometric Thinking (GT) according to van Hiele model. The study was conducted with pre and posttest non-equivalent control group quasi-experimental method. The control group were taught by conventional method while the experimental group learnt geometry through the use of Dynamic Geometry Computer Software. Convenient and purposive sampling were used for participants\u27 selection. The sample of the study was 87 ninth grade learners. A GMAT on geometric thinking was used as the data collecting instrument. Data analysis was done according to Van Hiele theory using ANOVA. The result showed that there was significant difference in the GT levels of the experimental and control groups, but the GT points were the same. The indication means the use of DGCS increase the learners\u27 GT. The improvement will enable learners in both secondary and technical colleges to make informed decision and solve problem in various fields in the future. Since learners enroll to TVET colleges at grade nine, the improvement will also help the learners when encountering problem in geometry in vocation education training. Lack of sufficient geometry thinking in learning geometry, make learners to be deficient in building foundational geometry thinking skills and problem solving which are useful in TVET colleges. This study suggest that further study is necessary to extend the investigation to more topics across the mathematics curriculum both in secondary and TVET colleges
Chapter 7: Technology-based teaching
Full text linkClassrooms are environments where teachers and students interact. This chapter provides approaches and tactics for managing teaching and learning in the classroom using technology-based pedagogy. Technology-based teaching, which effectively incorporates technological equipment or devices into the curriculum, is a powerful tool for instilling knowledge in students. In the twenty-first century, technology-based teaching involves electronic instruction using various tools such as computers, the internet, audio and video, satellite broadcasts, software applications, video conferencing, chat rooms, smartphones, websites, computer-based instruction, and CD-ROMs. These technology-based classrooms allow teachers and students to engage in ways that promote active participation and healthy cooperation. The chapter not only defines and discusses technology-based instruction but also highlights its numerous advantages and disadvantages, as well as the role of the educational environment and technological tools. It also provides valuable insights into the dos and don\u27ts of technology-based classrooms and effective technology-based activities. The chapter concludes with a few inspiring case examples of classes that have successfully integrated technology into their teaching methods, promoting active participation and enhancing student learning
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
