Making the implicit explicit: Supporting teachers to bridge cultures

In this paper, we report the results of a longitudinal action research project in which elementary teachers used a cultural framework (individualism–collectivism) to understand differences between the culture of immigrant Latino families and the culture of U.S. schools. Making explicit the culture-based beliefs implicit in home and school practices allowed teachers to think differently about their students and their own teaching, and with that change in thinking came the immediate and ongoing creation of a wide range of innovations to bridge home and school cultures. Shifting to a preschool emphasis, we discuss how the individualism–collectivism framework has been used in professional development for early childhood educators. A broad view of professional development is discussed including the role of college faculty, early childhood program administrators, teachers, and families. We suggest how such professional development might be mounted through use of methods and materials that promote explicit models of immigrant cultures to reduce home–school cultural mismatches for immigrant children.     

Delineating complex scientific fields by an hybrid lexical-citation method: An application to nanosciences

Relevance of bibliometric indicators on scientific areas critically depends on the quality of their delineation. Macro-level studies, often based on a selected list of journals, accept a high degree of fuzziness. Micro-level studies rely on sets of individual articles in order to reduce noise and enhance precision of retrieval. The most usual information retrieval process is based on lexical queries with various levels of sophistication. In the experiment on Nanosciences reported here, this process was used as a first step, to delineate a ‘seed’ of literature. It has strong limitations, especially for emerging or transversal fields. In a second step, the alternative approach of citation linkages, was used to expand the bibliography starting from lexical seed. The extension process presented is ruled by three parameters, two deal with the cited side (threshold on citation score, and specificity towards the field), one with the citing side (threshold on the number of relevant references) interplaying in the ‘referencing structure’ function (RSF) introduced in a previous work. This type of combination proves effective for delineating the transversal field of Nanosciences. Further improvements of the method are discussed.     

An assessment of debt‐for‐education swaps. Case studies on swap initiatives between Germany and Indonesia and between Spain and El Salvador

A decade has passed since participants in the World Education Forum committed themselves to achieve, by 2015, the six Education for All (EFA) goals under the Dakar Framework for Action. Despite significant progress, some of the goals are likely to be missed by a large margin. Besides the absence of a well co‐ordinated multi‐donor approach in education, another major problem is the lack of funds: the EFA financing gap in low‐income countries is now estimated at around $16 billion annually. This article zooms in on debt swaps as one particular instrument of innovative financing. More specifically it assesses the macro‐economic impacts of debt‐for‐education swaps and their relation to the aid approach now advocated by the donor community. It does so on the basis of theoretical insights from debt relief and case studies on recent swap initiatives between Germany and Indonesia and between Spain and El Salvador. Our conclusions are mixed. On the one hand, typical debt swaps suffer from macro‐economic flaws and, in view of competition amongst sectors, have limited potential in narrowing the EFA deficit. On the other hand, our case studies suggest that debt‐for‐education swaps can be engineered to better comply with the needs of recipient ownership and could in the future address deserving niche problems.     

Learning of colonial odor in the ant<Emphasis Type="Italic">Cataglyphis niger</Emphasis> (Hymenoptera; Formicidae)

Ants learn the odors of members of their colony early in postnatal life, but their ability to learn to recognize noncolony conspecifics and heterospecifics has never been explored. We used a habituation—discrimination paradigm to assess individual recognition in adult Formicine ants,Cataglyphis niger. Pairs of workers from different colonies were placed together for repeated trials, and their ability to discriminate the ant that they encountered from another familiar or unfamiliar ant was observed. Some ants were isolated between encounters, and others were returned to their home colonies. Our results suggest for the first time in ants that C. niger adults learn about individual ants that they have encountered and recognize them in subsequent encounters. Ants are less aggressive toward non-nestmates after they are familiar with one another, but they are aggressive again when they encounter an unfamiliar individual. Learning about non-nestmates does not interfere with an ant’s memory of members from its own colony.     

Representations of Fractions: Evidence for Accessing the Whole Magnitude in Adults

Proficiency with fractions serves as a foundation for later mathematics and is critical for learning algebra, which plays a role in college success and lifetime earnings. Yet children often struggle to learn fractions. Educators have argued that a conceptual understanding of fractions involves learning that a fraction represents a magnitude different from its whole number components. However, it is not well understood whether adults represent a fraction's magnitude similarly to whole numbers. This study investigated the distance effect during a comparison task using fraction pairs that discouraged comparing a fraction's components. Accuracy improved and reaction times decreased with greater distance between fraction pairs, showing a distance effect similar to that seen with whole numbers. This study suggests that a representation of a fraction's magnitude is present in the fully developed number system.     

Defining the attributes for specific playing positions in football match-play: A complex systems approach

ABSTRACT

Introduction

Talent identification and development programmes that retain and develop athletes are integral to the sporting success of National Governing Bodies in football. Currently, player attributes are studied in isolation without considering the complexity of interacting components of football performance. The current study applied a systems analysis framework to describe, in a structured and systematic way, the attributes for specific playing positions in football match-play. Methods: Eight high-level football coaches were interviewed. Models of the interacting attributes were developed for each position using Work Domain Analysis (WDA). Results: Six WDA models detail the attributes associated with each playing position. The models identified purposes of playing positions (restrict opposition actions, organise and coordinate, building up of offence, goal scoring and stretch opposition), performance-related measures and the functions required to achieve the playing position purposes (game play, psychological functions, time and space and player actions). Critically, the relationships between the purposes, measures, functions, processes, and objects are described in the models.     

Of sentimental value: collecting personal diaries from the First World War

ABSTRACT

Weeks after the Armistice was declared, Principal Librarian William Ifould of the Public Library of New South Wales recommended to Library Trustees that the institution begin to collect ‘private and official documents’ produced during the war. By early December 1918, advertisements began to appear in Australian and New Zealand newspapers, encouraging returning soldiers to sell their personal diaries to the Library. Known as the European War Collecting Project, this acquisition program was the first of its kind in Australia. This paper explores the Library’s acquisition of personal diaries written by those who served and analyses the appraisal methodologies carried out by State Library staff. This case study underscores the recent archival debate which has re-assessed the role of archivists in assessment, appraisal, preservation (and privileging) of some collections over others and argues that archivists mediate and consequently shape the collections in their institutions.     

Cross‐Validated Prediction of Academic Performance of First‐Year University Students: Identifying Risk Factors in a Nonselective Environment

Early prediction of academic performance is important for student support. The authors explored, in a multivariate approach, whether pre‐entry data (e.g., high school study results, preparative activities, expectations, capabilities, motivation, and attitude) could predict university students’ first‐year academic performance. Preregistered applicants for a bachelor's program filled out an intake questionnaire before study entry. Outcome data (first‐year grade point average, course credits, and attrition) were obtained 1 year later. Prediction accuracy was assessed by cross‐validation. Students who performed better in preparatory education, followed a conventional educational path before entering, and expected to spend more time on a program‐related organization performed better during their first year at university. Concrete preuniversity behaviors were more predictive than psychological attributions such as self‐efficacy. Students with a “love of learning” performed better than leisure‐oriented students. The intake questionnaire may be used for identifying up front who may need additional support, but is not suitable for student selection.     

Protective Factors and Compensation in Resolving Dyslexia

ABSTRACT

Two explanations for resolving dyslexia were investigated, one assuming resolving underlying deficits and another assuming compensatory mechanisms based on cognitive strengths. Thirty-six Dutch gifted secondary-school students with either persistent (n = 18) or resolving (n = 18) dyslexia participated. Groups, matched on IQ, were assessed on dyslexia- and intelligence-related cognitive risk and protective factors. Findings for the risk factors showed support for both the resolving-deficit and compensatory-mechanism theories: Resolving and persistent groups were comparable on phoneme deletion and nonalphanumeric rapid automatized naming, but resolvers outperformed students with persistent dyslexia on spoonerisms and alphanumeric rapid automatized naming. For the protective factors, resolvers consistently showed more pronounced cognitive strengths in verbal areas relevant for literacy development, which is in line with the compensatory-mechanism theory. We conclude that, besides underlying deficits resolving to some extent, compensation is a plausible explanation for resolving literacy difficulties in gifted students.
