The Features of Effective Online Professional Development for Early Childhood Educators
Get PDFThe purpose of this current study was to examine the effect of a preschool teacher intervention around the use self-monitoring and the online learning modules. The interventions were delivered online using: online learning modules that provided exemplars of the operationally defined instructional language supports. The study included 12 Head Start classrooms, with 21 lead and assistant teachers who were randomly assigned to one of two treatment conditions: (a) graphed feedback based on self-reported data, or (b) written feedback based on performance data from videos. An experimental research design was conducted to evaluate the treatment effects for teachers and children (n = 107). The results suggested that regardless of condition, the majority of teachers increased their total frequency of language facilitation strategies. Additionally, the results suggest that teachers’ receptive vocabulary skills and their role in the classroom (lead or assistant) may mediate the effect of the professional development intervention
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
Understanding the Impact of Teachers’ Language Skills on Professional Development
Get PDFThis professional development study explored how teachers’ receptive language skills impacted their use of language enhancement strategies. Twenty-one Head Start lead and assistant teachers participated in an online in-service designed to support their use of language enhancement strategies. Findings show that teachers’ receptive vocabulary predicted how often they used language strategies. Also, we found that prior to the professional development assistant teachers used fewer language enhancement strategies when compared to lead teachers. However, after receiving the professional development the gap between lead and assistant teachers’ use language enhancement strategies began to close
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

Teacher-Level Traits as Moderating Factors of Professional Development
Get PDFThis professional development (PD) study investigated the role of teachers’ initial receptive language skills on the implementation of language enhancement strategies. Head Start lead (n=12) and assistant (n=9) teachers received PD designed to increase their use of language enhancement strategies. Results indicated that teachers’ receptive vocabulary scores did predict their pretest language strategy usage; F(1, 19) = 6.40, p < .05, accounting for 25.2% of the variation in the frequency of language enhancing strategy. Additionally, there was a significant difference detected by role at pre-intervention indicating that assistants delivered fewer language enhancement strategies compared to lead teachers M = 41.25 (SD = 16.16) vs. M = 25.67 (SD = 11.98). However, post-intervention means demonstrated a closing of the gap between lead and assistant teachers’ implementation of language enhancement strategies. Results interpreted by discussing the importance of examining the moderating impact of teacher-level traits in evaluating the effectiveness of PD
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
