Key Factors Affecting the Implementation of Biotechnology Instruction in Secondary School Level Technology Education Classrooms
No full textThe growing impact of biotechnology globally and nationally over the past few decades has prompted the need for elevating general biotechnological literacy levels in all populations. This need is currently being addressed through the field of technology education (TE). Although included in the Standards for Technological Literacy (ITEA, 2000), the actual delivery of biotechnology instruction in TE classrooms has not realized broad implementation. Previous studies have recognized this issue and called for systematic research to identify key factors affecting the implementation of biotechnology instruction in secondary school level TE classrooms.
The purpose of this study is to identify the key factors affecting the implementation of biotechnology instruction in secondary level TE classrooms and establish predictive values for the identified factors. This study, which employs a research design grounded in both Rogers’ Diffusion Theory (2003) and Eccles Expectancy-Value Theory (2005), was conducted to address this implementation issue. This study involved the administration of a composite on-line instrument to collect demographic, attitudinal, motivational, and open-ended data related to the phenomena under investigation. Data collected from the on-line composite survey were analyzed through statistical (descriptive, independent t-tests, correlations, hierarchical multiple regressions) and thematic analysis. A total of 395 secondary school TE teachers across the five selected states (Virginia, New York, Connecticut, New Jersey, and Pennsylvania) participated in this study.
Analyses of the data led to the following conclusions. Insufficient implementation and preparation toward teaching biotechnology presented in this study are consistent with the low level of implementation of biotechnology instruction in TE classrooms revealed through prior studies. In addition, TE teachers’ motivation (expectancy, value, and cost), their preparation (pre-service courses and/or in-service PD), and infrastructure are all significant predictors for the implementation of biotechnology instruction. Thus, it is necessary for the TE teachers to have a variety of opportunities and support for developing their self-belief toward teaching biotechnology and experiencing the usefulness and importance of teaching biotechnology. The findings and conclusions drawn from the data analysis provide implications to the TE teachers and pre-service teacher preparation institutes.Ph. D
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
Meta-analysis on Students’ Effects of Technology Education Classes under the South Korean National Curriculum
No full textIn South Korea, Technology education is one of the national curriculum compulsory subjects, and despite the importance and value, public awareness toward technology and technology education is very low. Whenever the curriculum is revised, the value and place of technology education have been challenged. The purpose of this study is to analyse effects on students of technology education classes. Meta-analysis is conducted to calculate the effect size of technology education classes in the Republic of Korea. Data are collected through an integrated searching engine of Korean academic database. From 2000 to 2022, 61 studies are analysed by Comprehensive Meta Analysis 4.0. The result shows an intermediate effect size in technology education classes. A total of 148 effect sizes are analysed by dividing the subcategories into publishing type, teaching method, school level, experimental type, and dependent variable. For the publishing type, academic journals and thesis papers show the intermediate effect size. Particularly, studies for elementary school level indicate a high effect size, followed by middle school and high school. The dependent variables show intermediate effect sizes of the order of affective variables (e.g., attitude, motivation), psychomotor variable, and cognitive variables (e.g., academic achievement). Based on the findings, this study can make the following recommendations. More studies for proving the value and importance of technology education classes should be conducted.
