An analysis of professional practice Ed.D. dissertations in Educational Technology

The University of Florida offers an online professional practice Ed.D. focused on Educational Technology. Twenty-three students have completed professional practice dissertations and graduated since the program’s inception in 2008. The purpose of this article is to share what these dissertations have looked like and to begin a dialogue about professional practice dissertations completed in online educational technology programs. Specifically, we (1) provide an overview of different ways professional practice Ed.D. dissertations are structured, (2) share guiding principles for professional practice dissertations in our Ed.D. program, (3) analyze the ways in which these guiding principles played out in the dissertations and (4) discuss the implications of our analysis for our program and for other online professional practice programs in Educational Technology.     

Approaching Participation in School-Based Mathematics as a Cross-Setting Phenomenon

This article reports on an ethnographic study of a 10-year-old's pursuit of school-based mathematics across school and home to suggest that participating in school-based mathematics is a cross-setting phenomenon in at least 2 ways. First, I illustrate how accomplishing school-based mathematics literally extends into the home and how individuals recruit resources from their histories of participation in alternative settings to accomplish the work of school-based mathematics. Second, I show how a youth's social identification in the classroom is shaped by his teacher's partial accounts of how learning is arranged for in the home. Approaching participation in school-based mathematics as a cross-setting phenomenon illustrates the complexity inherent in participating in schooling and raises questions about how to coordinate schooling across school and home settings.     

Reading to Children and Listening to Children Read: Mother–Child Interactions as a Function of Principal Reader

Research Findings: Although storybook reading has received considerable research attention, listening to children read has been the source of much less inquiry. In this study, 40 mother–child dyads were videotaped during adult-to-child and child-to-adult reading. Relations between book-related themes (e.g., types of talk), maternal evaluative feedback (e.g., praise, criticism), maternal miscue feedback (e.g., graphophonemic clues, terminal feedback), and child engagement (e.g., laughter, questions) were analyzed. The results suggest that the development of literacy appreciation and literacy skill can occur during the same storybook-reading session. Specifically, when mothers read to their children, communication about the illustrations was associated with increased child engagement, yet a positive correlation was also observed between text-related productions and child engagement. When children read to their mothers, text-related productions were featured more prominently. After children made reading errors (miscues), graphophonemic and terminal feedback were the 2 most frequent responses by mothers. In addition, graphophonemic cues were positively associated with child engagement. Practice or Policy: In sum, the results demonstrate that adult-to-child and child-to-adult reading serve the goals of both literacy acquisition training and literacy appreciation; furthermore, orienting children toward the text during either session did not hamper child engagement.     

New modeling approach of secondary control layer for autonomous single-phase microgrids

In a microgrid (MG) topology, the secondary control is introduced to compensate for the voltage amplitude and frequency deviations, mainly caused by the inherent characteristics of the droop control strategy. This paper proposes an accurate approach to derive small signal models of the frequency and amplitude voltage at the point of common coupling (PCC) of a single-phase MG by analyzing the dynamics of the second-order generalized integrator-based frequency-locked loop (SOGI-FLL). The frequency estimate model is then introduced in the frequency restoration control loop, while the derived model of the amplitude estimate is introduced for the voltage restoration loop. Based on the obtained models, the MG stability analysis and proposed controllers’ parameters tuning are carried out. Also, this study includes the modeling and design of the synchronization control loop that enables a seamless transition from island mode to grid-connected mode operation. Simulation and practical experiments of a hierarchical control scheme, including traditional droop control and the proposed secondary control for two single-phase parallel inverters, are implemented to confirm the effectiveness and the robustness of the proposal under different operating conditions. The obtained results validate the proposed modeling approach to provide the expected transient response and disturbance rejection in the MG.     

The “Wicked Problem” of Neutral Description: Toward a Documentation Approach to Metadata Standards

Increasingly, metadata standards have been recognized as constructed rather than neutral. In this article, we argue for the importance of a documentation approach to metadata standards creation as a codification of this growing recognition. By making design decisions explicit, the documentation approach dispels presumptions of neutrality and, drawing on the “wicked problems” theoretical framework, acknowledges the constructed nature of standards as “clumsy solutions.”     

Performance strategies of US Olympians in practice and competition

Until recently, no self‐report instruments have examined psychological skills use in both practice and competition. In light of the significant role of practice in sport performance outcomes, a need exists to measure these skills in both domains. This study was designed to investigate differences in performance strategies of US Olympians in both practice and competition. The Test of Performance Strategies was administered to 176 US participants in the 2000 Sydney Olympic Summer Games. Discriminant function analyses demonstrated significant differences between medalists and nonmedalists in both the competition and practice performance strategies. Furthermore, significant gender and age differences were identified for competition strategies only. The 16 subscales of the TOPS, with two exceptions, create an internally stable instrument with moderate predictive ability relative to quality of sport performance, gender, and age in this elite sample of athletes.

Testing and ideology: policy debates about literacy assessments for Colorado’s bilingual students

ABSTRACT

The Colorado Reading to Ensure Academic Development Act requires grade-level attainment in literacy in English for students in grades K-3. Its practical outcome, however, has been to pressure schools with bilingual programs to shift their instructional language allocations towards more English in the early grades. Proposed rule revisions debated by the state Board of Education sought to facilitate testing in students’ language of instruction for those in bilingual programs. Analysis of written and verbal opposition to the proposed rule revisions demonstrates the persistence of insidious ethnoculturalist discourses opposing bilingual education as well as the cooptation of liberal multiculturalist discourses that, while framing bilingualism as an asset, argue that it is underdeveloped in bilingual programs that do not include English instruction from the outset. Given that bilingual instruction has demonstrated time and again that it benefits students acquiring English in schools, such new discursive turns pose a threat that must be recognized to fend off further legislative and regulatory attempts against bilingual education.
