Are Accommodations for English Learners on State Accountability Assessments Evidence-Based? A Multistudy Systematic Review and Meta-Analysis

The objectives of this two-part study were to: (a) investigate English learner (EL) accommodation practices on state accountability assessments of reading/English language arts and mathematics in grades 3–8, and (b) conduct a meta-analysis of EL accommodation effectiveness on improving test performance. Across all distinct testing programs, we found that at least one EL test accommodation was provided for both test content areas. The most popular accommodations provided were supplying students with word-to-word dual language dictionaries, reading aloud test directions and items in English, and allowing flexible time/scheduling. However, we found minimal evidence that testing programs provide practitioners with recommendations on how to assign relevant accommodations to EL test takers’ English proficiency level. To evaluate whether accommodations used in practice are supported with evidence of their effectiveness, a meta-analysis was conducted. On average, across 26 studies and 95 effect sizes (N = 11,069), accommodations improved test performance by .16 standard deviations. Both test content and sampling design were found to moderate accommodation effectiveness; however, none of the accommodations investigated were found to have intervention effects that were statistically different from zero. Overall, these results suggest that currently employed EL test accommodations lack evidence of their effectiveness.     

THE IMPLICATIONS OF NATIONAL POLICIES IN THE UNITED STATES,BRAZIL, EL SALVADOR,AND PERU ON EARLY CHILDHOOD TEACHER EDUCATION

It may seem obvious but the world is filled with believers in the value of good care and attention to children during the earliest months and years. That belief is embedded in virtually all cultural traditions. Indeed, both common wisdom and hard scientific research evidence lead to the forceful conclusion that the earliest years of life are critical in the development of the intelligence, personality, and the social values and behaviors that will characterize later life... But if the value of the early years is so evident... why is there such neglect by families and social institutions? Among the reasons that might be offered are the following: Families living in extreme poverty or victimized by war and famine, may be so busy surviving that they cannot give the

loving attention to their children they would like to give. Families living in luxury may be too busy making money, or spending it, to give the needed time to their children. At the same time, some institutions that could help families to help their children take the position that the child development is best left to families. ‐‐Robert G. Myers, 1991     

Creating a Research Center: Space for Collaborations and Conversations

This report describes the creation of a library research center, where a team of librarians provide flexible, convenient, and personalized research assistance to students. A research center creates a positive user experience for students and places collaboration—both among librarians and students—at its core. Next-generation reference models must provide spaces and environments for students and librarians to engage in meaningful and deep information literacy conversations as outlined in the ACRL Framework for Information Literacy for Higher Education.     

The Impact of Grey Literature in Advancing Global Karst Research: An Information Needs Assessment for a Globally Distributed Interdisciplinary Community

A survey of the global karst community was conducted in 2006. The survey was distributed via the World Wide Web to known karst researchers. The instrument was designed to generate an initial inventory of core grey information types, to assess levels of usage of grey information by the respondents, and to gauge the karst community’s willingness to participate in building and expanding both this collection and the associated controlled vocabularies.     

Disinfection by-products effect on swimmers oxidative stress and respiratory damage

Disinfection by-products (DBPs) are generated through the reaction of chlorine with organic and inorganic matter in indoor swimming pools. Different DBPs are present in indoor swimming pools. This study evaluated the effects of different chlorinated formations in oxidative stress and lung damage in 20 swimmers after 40?min of aerobic swimming in 3 indoor pools with different characteristics. Biological samples were collected to measure lung damage (serum-surfactant-associated proteins A and B), oxidative stress parameters (plasma protein carbonylation and malondialdehyde, and whole-blood glutathione oxidation), and swimming exertion values (blood lactate) before and after exercise. Free chlorine and combined chlorine in water, and chlorine in air samples were determined in all the swimming pools. Chlorination as disinfection treatment led to the formation of chloramines in water samples, mainly mono- and dichloramine. However, free chlorine was the predominate species in ultraviolet-treated swimming pool. Levels of total chlorine increased as a function of the swimming activity in chlorinated swimming pools. The lower quality of the installation resulted in a higher content of total chlorine, especially in air samples, and therefore a higher exposure of the swimmer to DBPs. However, the concentration level of chlorinated DBPs did not result in significant variation in serum-surfactant-associated proteins A and oxidative stress parameters in swimmers. In conclusion, the quality of the installation affected the DBPs concentration; however, it did not lead to lung epithelial damage and oxidative stress parameters in swimmers.     

Metadata and Quality in Digital Repositories and Libraries from 1995 to 2015: A Literature Analysis and Classification

The purpose of this article is to study a broad set of journal papers related to metadata and quality in digital repositories and libraries, and to provide a quantitative analysis of the relevant research. It also aims at identifying open issues and future directions for research. A detailed search was carried out in relevant journals of information science, computer science, and library science; mainly, that allowed us to identify an extensive corpora of relevant work. The identified papers were classified based on an existing framework and a statistical analysis was carried out on the main classifications used within the framework. The analysis of the 702 papers identified, led to a series of statements for the field examined, focusing on the type of research carried out, the research methods deployed, and the research claims made. In addition, the papers were classified based on their target audiences, disciplines, as well as institutional and geographical origins. The article identifies areas in the literature that have not been addressed, as well as areas for future research. It also provides a clear image of the areas already researched, analyzing scientific literature that covers 20 years of repository/library deployment. This article makes an original contribution for researchers, practitioners, and managers of digital repositories and libraries alike as it provides a set of specific recommendations for the metadata and quality in digital repositories and libraries research agenda, along with a thorough analysis and classification of the research carried out so far.     

CHARACTERIZING THEMATIZED DERIVATIVE SCHEMA BY THE UNDERLYING EMERGENT STRUCTURES

This paper reports on different underlying structures of the derivative schema of three undergraduate students that were considered to be at the trans level of development of the derivative schema (action–process–object–schema). The derivative schema is characterized in terms of the students’ ability to explicitly transfer the relationship between a function and its first derivative to the derivative function and the second derivative. This conscious shift of properties of derivatives is differently manifested by the students in the trans level of development of the derivative schema and can be considered evidence of the different characteristics of the thematization of derivative schema. From here we suggest that there are different underlying structures in the constructed schema due to the consciousness in which students use the relations between a function and its derivative.     

Invented spelling activities in small groups and early spelling and reading

Our aim was to assess the impact of an invented spelling programme conducted in small groups on children’s written language acquisition in Portuguese. We expected the experimental group to have better post-test results than the control group in spelling and reading. Participants were 160 preschool-age children who were randomly divided into an experimental and a control group. Their age, cognitive ability, knowledge of letters and phonological abilities were controlled. Children’s spelling and reading were evaluated in a pre- and a post-test. In-between, experimental group participated in an invented spelling programme in small groups and the control group in story readings. The experimental group showed better results in spelling and reading in the post-test than the control one. Different dynamics occurred in the small groups which had different impacts on children’s acquisitions. These results provide empirical support for the proposal that invented spelling should be incorporated into early literacy instruction.     

The Dialectic Relationship between Research and Practice in Mathematics Teacher Education

This paper addresses issues linking research in student teacher learning with reflection on practice in mathematics teacher education. From a situated perspective on learning and practice, we explore our own practice as teacher educators while researching student teacher learning in our classrooms. We describe a study on student teacher learning, considering student teacher learning as a “process of becoming”, and how the results of this research have affected our development as mathematics teacher educators and members of a community of inquiry. Our work shows how in the mathematics teacher education context the relationship between theory and practice becomes an element of both teacher educator and researcher development.     

School Leadership Teams: A Process Model of Team Development

A number of studies have analyzed the factors that influence successful site-based management (SBM), but none has examined the relationships among those factors or their predictive value. In California, school leadership teams (SLTs) represent an aspect of school based management that is teacher-led and oriented to curriculum and school reform. The teams do not operate within the context of a prescribed programmatic formula and are not encumbered by personnel and budgeting decisions as are SBM committees. They receive training to learn to work together to improve teaching and learning at their schools with the goal of affecting student outcomes. To try to understand which factors are predictive of effective SLTs, we analyzed survey data from 71 elementary and 71 secondary SLTs that had received 1 full year of training. Using path analysis, we tested a model that identified the relationships among the factors that are most likely to influence the team's ability to focus on teaching and learning. The strongest predictor of their ability to focus on this important variable was the use of data collected within the school to identify needs and guide future decisions. Our findings also advanced our understanding of how SLTs work and revealed: (1) the importance of developing team skills in problem-solving as a predictor of many other positive relations; (2) the significance of strong professional relations as a predictor of positive district relations, use of data, and a focus on teaching and learning; and (3) the paradox of teams needing to hear parent and student voices and, at the same time, coping with the negative effect on professional relations if they are present on the team.
