Digitization of civil technology practical lessons for project-based learning at Ekurhuleni-East, South Africa
No full textIn this modern education system, digitizing education at the secondary school level will be crucial to
preparing learners for a world in which technology will become a valuable tool to make Civil Technology
practical skills learning easy and more integrated into real-life projects. Digitization of practical lessons
involves transferring traditional in-person hands-on practical demonstrations into digital formats using
images and video recordings. However, following a teacher-led class, this teaching approach eases
teachers' workload because learners will be using digital resources like smartphones and tablets to
recall and practice the demonstrated practical skills; and that creates enough time for teachers to
monitor and evaluate Project-Based Learning (PBL) activities in the classroom or workshop. Thus, using
a case study research strategy, this study aimed to investigate whether digitization of practical lessons
could assist in overcoming the challenge of limited time for PBL activities in schools. Purposive sampling
was used to select twelve (12) Civil Technology teachers to participate in this study. Non-participant
observation and semi-structured interview instruments were used as data-collection methods. Data
collected was analysed using thematic analysis. The study found that Civil Technology teachers
preferred the hands-on demonstration method and video recordings to conduct PBL. Furthermore, this
study found that most Civil Technology teachers from Ekurhuleni East, South Africa do have Information
and Communication Technology (ICT) knowledge and their schools have access to educational
technologies like computers, smart boards, and internet coverage in their yards that may support digital
teaching and learning. Therefore, this study recommends the digitization of Civil Technology practical
lessons for effective teaching and convenience purposes
Factors influencing construction technology teachers' ability to conduct simulations effectively
Full text linkThe efficacy of teaching hands-on skills practical activities requires teachers' willingness to implement technology enhanced pedagogy through the creation of relevant subject simulations. Teachers should be competent with workplace basics in order to prepare and demonstrate construction practical lessons that promote undeniably marketable skills that students can use to contribute to this competitive economy. The goal of this research was to look into the factors that influence Construction Technology teachers' effective teaching when conducting simulations. Purposive sampling was used to identify a total of five (5) teachers to participate in this study. Non-participant observation and semi-structured interviews were also used as a complementary data collection tool. The conceptual framework that guided this study workplace basics. According to the findings of this study, most Construction Technology teachers lack basic workplace skills as well as the ability to maintain effective teaching when conducting simulations. This is due to poorly made artifacts and a failure to use all available tools and equipment. Furthermore, the study discovered that teachers do not always plan for their theory lessons, and the challenge is even more difficult for practical lessons. The study suggests that Construction Technology teachers attend practical skill development training for Curriculum Assessment Policy Statement (CAPS) 2 while also visiting industries, universities, and colleges to gain exposure to the trade environment in order to stay current with technological developments. Most importantly, teachers should engage in ongoing professional development and learn the fundamentals of the workplace basics skills.</jats:p
Equipping Civil Technology Teachers with Hands-On Skills and Educational Resources for Effective Teaching of Practical Lessons
Full text linkContinuous professional development for teachers will always be prioritized, especially in cases where there are obvious and conspicuous gaps in their subject-matter expertise and when they handle practical skills exercises with inadequate planning and delivery. Hence, this study explores the effects of equipping Civil Technology teachers with hands-on skills and provision of educational resources for effective teaching of practical lessons. This study purposefully sampled nine (09) Civil Technology teachers from Ekurhuleni East, Gauteng province of South Africa. This study was hinged on Stronge’s qualities of effective teachers as its framework. This study adapted a mixed method design where closed-ended questionnaires and semi-structured interviews were considered relevant data collection instrument and sources. A sequential explanatory design was used to analyze the collected data. The findings reveal that even though teachers get continuous hands-on skills training from the Gauteng Department of Education (GDE) annually, the trainings are often too generic and do not adequately boost teachers with confidence to teach specific skills (i.e., construction and plumbing) to learners. As a result, Civil Technology teachers could not actualize their continuous professional development training as an element of learning to become innovative skills teachers. The survey found that while certain Ekurhuleni East schools have instructional tools, some of the teachers were not trained to use them, which made it difficult to effectively teach practical lessons in Civil Technology. Therefore, this study recommended that the Gauteng Department of Education should focus on discipline specific instructional strategies that will promote innovation in skills-based activities in Civil Technology. 
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
How Civil Technology Teachers Teach Woodworking Practical Skills in Schools: A Case of Ekurhuleni East, South Africa
No full textIn this Fourth Industrial Revolution (4IR) date, Technology Education teachers are exposed to a of variety teaching methods to ensure that they practice teaching practical skills effectively. Thus, Civil Technology teachers may use different methods such as practical demonstration of skills, videos and photos for teaching woodworking practical skills in schools. The goal of this research was to enquire how Civil Technology Teachers teach woodworking practical skills in schools at Ekurhuleni East, South Africa. Purposive sampling was used to identify a total of Nine (9) Civil Technology teachers to participate in this study. Mixed method research was used where semi-structured interviews and explanatory survey research were combined and integrated as a complementary data collection tool. According to the findings of this study, most of the Civil Technology teachers use practical demonstration of skills as a method to teach woodworking skills in schools. This is because practising the skills in front of the students in the workshop will not only benefit the students but will also develop teachers’ effective teaching skills for woodworking practical skills. The study recommended that teaching and learning time allocation for Civil Technology must be increased so that teachers can be able to demonstrate practical woodworking skills and also monitor hands-on activities. This paper will aid Civil Technology teachers in exploring some ways of teaching that can benefit all students regardless of their class differences when teaching woodworking practical courses
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
