In this four-year project called Developing Preservice Elementary Teachers' Ability to Facilitate Goal-Oriented Discussions in Science and Mathematics via the Use of Simulated Classroom Interactions (GO Discuss), Educational Testing Service and Mursion developed, piloted, and validated a set of performance-based tasks delivered within a simulated classroom environment in order to improve preservice elementary teachers’ ability to orchestrate discussions. These tasks provided opportunities for preservice teachers in science and mathematics to facilitate discussions with five upper elementary student avatars (fifth grade) where the focus is on disciplinary argumentation within two content domains: fractions (mathematics) and structure/properties of matter (science). The overall goal of this research was to develop a validity basis for the use of such tools as formative assessment tasks that can be integrated within educator preparation programs to increase the amount, variety, and quality of clinical practice opportunities currently available to preservice elementary teachers.
We scored the pre-service teachers’ video-recorded performances for the eight tasks in two waves. We scored the formative tasks (M2, M3, M4, S2, S3, and S4) immediately following each data collection and returned written formative feedback to the pre-service teachers within two weeks. For each video-recorded discussion, the formative feedback consisted of general statements and specific feedback about the strengths and areas for growth tied to each indicator in the rubric. The summative scoring (M1 and S1 pre- and post-) discussions were scored at the end of the project. To help reduce rater bias, we coded the videos so that raters could not determine if a video was a pre-service teacher’s pre- or post- video. All summative and formative discussions were scored using the same rubric.
This specific data project includes materials for the scoring and development of formative feedback reports of preservice teachers' performances in the simulated classroom.

Some files appear in different formats with identical content. This is intentional. ETS wants to encourage adaptation of the deposited materials (which might be easier to implement in Word documents), but also wants to ensure that images and math notations are rendered correctly for secondary users (best preserved in PDF)

This specific data project includes materials for non-task specific simulation specialist training. A simulation specialist serves as the “human-in-the-loop” during each simulated discussion. The simulation specialist is trained to provide student responses and control the movements of the student avatars in the simulated classroom. The non-task specific training teaches simulation specialists about the five student avatars and their unique vocal and background profiles. We also provided training on specific guidelines, called simulation discussion guidelines, that include information on standard protocols we wanted all simulation specialists to follow during the discussions for how to respond to the teacher’s prompting (or lack of prompting) to engage the students in direct peer-to-peer interactions. The non-task specific training also included instruction on how to set up and use the various technology components, including how to video record the pre-service teachers’ discussion performances and how to use the shared workspace.
The task-specific simulation specialist training for each task can be found in that task's respective data project.

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
