A Quest for Equity? Measuring the Effect of QuestBridge on Economic Diversity at Selective Institutions

In response to growing income stratification in higher education, President Obama convened a White House Summit in 2014 where over 100 selective institutions committed to increasing the number of low-income students on their campus. One way colleges proposed to do so is through partnerships with college access organizations like QuestBridge, a nonprofit organization that aims to increase the percentage of low-income students at elite universities. While institutions purport that QuestBridge improved socioeconomic diversity, empirical research has not confirmed these claims. In this study, we estimate the effect of QuestBridge on overall access of Pell eligible students at partner institutions using quasi-experimental methods. We find no increase in the economic diversity of colleges after establishing a partnership with QuestBridge, except for colleges simultaneously partnering with QuestBridge and enacting no-loan financial aid policies. We also consider whether participation in QuestBridge increases institutional status through larger application volumes and increased selectivity, and discuss implications for research and practice in the area of stratification.     

A critical review of education support practices in Spain

ABSTRACT

The objective of this study is to analyse different models of educational support that are used in schools with public funding from the perspective of support teachers, counsellors and members of management teams. Participants were 79 professionals from the three areas mentioned above. The methodological approach was a phenomenological qualitative one using focus groups and subsequent qualitative analysis of the data. The systems of categories and subcategories underwent a progressive process of triangulation. The results show that professionals identify support practices that can be divided into two differentiated models: a traditional model linked to a medical perspective of providing personal support to the most vulnerable students and a support model consistent with inclusive education. There are also discrepancies among professionals, especially about the need for support to be provided within the reference classroom. The discussion focuses on identifying essential aspects, to more effectively support students and teachers in an ordinary school context. In addition, professionals question the regulations for their disconnection from the reality they experience in schools. All this requires a rethinking of the functions of support teachers supported by careful initial and ongoing training.     

Lectura y escritura de palabras a través de la ruta fonologica

Resumen

En este trabajo se investigó si los mecanismos encargados de transformar los grafemas en fonemas son los mismos que transforman los fonemas en grafemas, que funcionan en ambas direcciones o si por el contrario se trata de mecanismos independientes. Para ello se presentó una lista de 40 pseudopalabras para su lectura y escritura a 104 niños de los primeros niveles de escolaridad. Los datos obtenidos parecen indicar que se trata de procesos distintos, ya que no existe concordancia entre las respuestas obtenidas en una y otra tarea. Niños que transformaban correctamente determinados grafemas en fonemas fallaban al convertir esos mismos fonenas en grafemas, y viceversa. Estos resultados podrían tener importantes implicaciones en el aprendizaje de la lectura y la escritura.     

Assessing the psychometric properties of Kember and Leung’s Reflection Questionnaire

Reflective thinking is often stated as a learning outcome of baccalaureate nursing education, and as a characteristic of a competent professional; however, no consistent method exists to assess the extent to which students engage in reflective thinking. To address this need, Kember and Leung developed and tested a self-report questionnaire based on Mezirow’s conceptualisation of levels of reflective thinking. The purpose of this study was to test the psychometric properties of the Reflection Questionnaire, developed by Kember and Leung. A convenience sample (n?=?538) of third-year baccalaureate nursing students from four collaborative nursing programmes in Ontario was used. Ethical approval was secured from 10 sites. Second-order confirmatory factor analyses (CFA) were used to test the factor structure of the Reflection Questionnaire. This research was part of a larger study on reflective thinking and is a first step in validating a four-level measure of reflective thinking, in educational environments, with baccalaureate nursing students. The results of the second-order CFA provide support for the construct validity of reflective thinking. Results of this study contribute to the evidence supporting the reliability and validity of the questionnaire. Nurse educators can use this information when implementing the questionnaire, and learning the extent to which students are engaging in the reflective thinking process.     

Race and Special Educational Needs in the 1990s

Fernando Almeida Diniz, currently in the Faculty of Education at The University of Edinburgh and formerly Reader in Special Needs in Education at the University of Greenwich, considers the effects of 'institutionalised racism' on the education of black and ethnic minority children with special educational needs.     

Strong delay-independent stability of linear delay systems

This paper presents a new necessary and sufficient condition for testing the strong delay-independent stability of linear systems subject to a single delay. The proposed method follows from the use of matrix polynomials constraints and the Kalman–Yakubovich–Popov lemma. The resulting condition can be checked exactly by solving a feasibility problem in terms of a linear matrix inequality (LMI). Simple numerical examples are given to show the effectiveness of the proposed method.     

Dynamics of players’ relative positioning during baseline rallies in tennis

Abstract

This study analysed how the relative positioning of players on court influenced patterns of interpersonal coordination in baseline rallies in tennis. We developed a model (PA index) that assigns a weight to the position of each player on court and determines a positional advantage, based on the relative proportionality between the lateral and longitudinal displacement values during rallies. To test the model, data from 27 randomly-selected baseline rallies from three ATP World Tour matches (professional tennis players' tournaments organized by Association of Tennis Professionals) on clay were analysed. Results revealed that the PA index of players on court described their interpersonal coordination dynamics during baseline rallies. It also identified the emergence of rally breaks in the interpersonal coordination patterns of competing dyads that led to a point being scored. Data suggest that positional advantage data may assist coaches in the design of training tasks to enhance players' court coverage and performance during competitive interactions, acting as a valuable tool for performance analysis in tennis.     

Data-mining techniques in detecting factors linked to academic achievement

In light of the emergence of statistical analysis techniques based on data mining in education sciences, and the potential they offer to detect non-trivial information in large databases, this paper presents a procedure used to detect factors linked to academic achievement in large-scale assessments. The study is based on a non-experimental, cross-sectional design and a sample of 18,935 high school students from 99 educational institutions in Baja California state (Mexico). The information was collected from ENLACE tests and context surveys given to students in Baja Caclifornia. Decision trees were used to apply classification techniques, and the results indicate that personal factors are most indicative of academic performance, followed by school-related and social factors. In conclusion, the paper discusses the similarities between the results obtained and those shown in literature, highlighting how simple decision trees allow a greater explanation and interpretation than other models and techniques.     

Reaction time and muscle activation patterns in elite and novice athletes performing a taekwondo kick

ABSTRACT

Fractionated reaction time can be used to determine distinct epochs known as pre-motor, response and movement times (MTs) of a reaction time task. The purpose of this study was to compare elite and novice athletes performing a taekwondo kick in terms of the fractionated reaction time and electromyography (EMG) activation patterns of the muscles of the striking lower limb and the lower back. We hypothesised that the pre-motor time, response time (RT) and MT would be the shorter for elite athletes compared to novices. We collected data on 13 elite and 10 novice athletes when performing a roundhouse kick. The experiment included EMG electrodes placed on five low back and lower extremity muscles and an electrogoniometer placed on the kicking knee. We found that pre-motor time was shorter and the RT was longer for elite athletes than novice athletes. Moreover, the integrated EMG of the main knee extensor does not differ between groups though other leg and trunk muscles do. The results allow coaches and teachers to understand this particular taekwondo kicking movement which could ultimately improve the technique in order to establish training and teaching goals.
