Examining the Use of Video Analysis on Teacher Instruction and Teacher Outcomes: A Meta-Analysis
Get PDFThe purpose of this replicated systematic review (SR) and meta-analysis was to examine the literature base of single-case research design studies using video analysis to determine the intervention’s effectiveness on teacher outcomes. Using a primary search and an ancestral, citation, and first author searches, this study evaluated participant, student, and setting characteristics in dissertations and peer-reviewed articles published from 2010-2020. A total of 24 included articles were coded for descriptive analysis and design quality. For the meta-analysis, a total of 16 articles were reviewed for statistical analysis, in which a between-case standardized mean difference was used to calculate effect sizes. Results indicate praise (n = 6) and fidelity of implementation (n = 6) had the largest effect size that continue to define video analysis as a promising practice. Recommendations for future practice include continued studies using video analysis with diverse educators, students, and settings that meet design quality standards as well as increasing sample size to prove the generalizability of video analysis. Addressing these recommendations will support video analysis becoming an evidence-based practice (EBP) for educator development
From Policy to Practice: Identification of State Approaches to Mesoamerican Language Identification
Get PDFThis study examined how states implement federal guidelines for identifying non-English languages, focusing on discrepancies and gaps in statewide language codes and processes used to document students' language backgrounds, with an emphasis on Mesoamerican languages. Using Critical Policy Analysis (CPA), the research analyzed how state policies address federal requirements for language identification and the documentation of Mesoamerican Indigenous languages. Iterative memo-writing techniques were employed to systematically categorize and analyze state policy data, uncovering patterns in the identification and recording of these languages. Additionally, a regression discontinuity model evaluated the impact of Oregon's updated language codes on the precise identification and documentation of Mesoamerican languages. Results indicate that states require more flexible student information systems, training, and resources to ensure accurate and comprehensive documentation of linguistic diversity, particularly for Mesoamerican languages. Limitations and future directions are discussed, along with recommendations for refining state-level language implementation of federal requirements
Increasing Observations and Feedback Efficiency to Improve Instructional Quality in Small Group Intervention Settings
Get PDFThe current study investigated the reliability and validity of using short observations with an observation tool designed to measure implementation of small group interventions. Intervention lessons for eight instructional groups from two schools were video recorded for nine weeks, and post-test assessments of reading decoding were administered to 31 at-risk kindergarten students. Videos of intervention instruction from weeks two, five, and eight, each representing a phase in the intervention period, were used within this study for measuring implementation. Each video was divided into three ten-minute segments representing the beginning, middle, and end of each intervention lesson. Video segments were coded for implementation using the Quality of Intervention Delivery and Receipt tool (QIDR; Harn, Forbes-Spear, Fritz, & Berg, 2012). Overall, the results of this study indicate that a) reliability can be achieved when using 10-minute observations, b) QIDR scores obtained from 10-minute segments are strongly correlated with scores obtained from full-length observations, c) there is no statistical difference in scores obtained from full-length observations and those obtained in 10-minute segments, and d) QIDR scores obtained from both full-length and 10-minute segments accounted for group differences in student outcomes, with lesson segments obtained from the end of lessons accounting for the most variance. Implications for research and practice are discussed, including the importance of thorough training and calibration to maintain reliability, as well as the feasibility and utility of providing frequent observation and feedback through shorter observations
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
