De la exposición histórica que hemos dado ya, se desprenden dos concepciones principales que pueden resumir los mecanismos patogenéticos de la afasia. Una es la neurológica y la otra la psicológica.     

Predicting transition and adjustment to college: biomedical and behavioral science aspirants’ and minority students’ first year of college

The purpose of this study is to explore key factors that impact the college transition of aspiring underrepresented minority students in the biomedical and behavioral sciences, in comparison with White, Asian students and non-science minority students. We examined successful management of the academic environment and sense of belonging during the first college year. Longitudinal data were derived from the Higher Education Research Institute’s (HERI) 2004 Cooperative Institutional Research Program (CIRP) Freshman Survey and the 2005 Your First College Year (YFCY) Survey. Using a reformulation of the integration model (Nora, Barlow, and Crisp, 2005), we find concerns about college financing, negotiating family support and responsibility, and campus racial dynamics (perceived and behavioral) affect student adjustment and sense of integration in the first year. This study was made possible by the support of the National Institute of General Medical Sciences, NIH Grant Number 1 RO1 GMO71968-01.

The Law of Unintended Consequences: The ‘Real’ Cost of Top-Down Reform

In most jurisdictions around the world,governments, in the name of economiccompetitiveness, have imposed comprehensive andquite dramatic changes on state schools. Mostchanges require a more centralized and rigorouscurriculum for pupils, a plethora ofaccountability measures and mandatoryin-service for teachers, and carefully definedand more onerous responsibilities for schoolleaders. The province of Ontario is nodifferent. Since 1995, its educational systemhas experienced quite revolutionary changes– all instituted with break-neck speed. At thesame time most schools in Ontario are employinginternal change strategies to address theseoutside pressures. These change forces havecoalesced to redefine the work and lives ofteachers and school leaders in many intendedand unintended ways. There is a substantialliterature on both external and internal changeforces, but very little has been written aboutthe conjunction of these change forces with thepersonal side of change for teachers andleaders. Based on two studies undertaken by theInternational Centre for Educational Change atthe Ontario Institute for Studies inEducation/University of Toronto, this paperexamines the unintended consequences of thesechange forces on the teachers and principals ofone secondary school in Ontario, Canada. Theteachers and leaders of Lord Byron High Schoolare not averse to change and are generallyquite content to do whatever is in the bestinterests of their students. The school has along history of innovation and change and areputation for attending to a wide diversity ofstudent needs.Through the use of multiple conceptual lenses,this paper addresses the unintendedconsequences of systemic change to the schooland its teachers and principals. At a time whenteacher shortages and teacher morale aregrowing problems for many educationaljurisdictions, this investigation will point toan urgent need to build better bridges ofunderstanding between policy makers and policyimplementers, and for researchers to provideresearch that is more sensitive to the work andlives of real people in real schools.

The effect of adaptivity on the reliability coefficient in adaptive comparative judgement

Comparative Judgement (CJ) is an increasingly widely investigated method in assessment for creating a scale, for example of the quality of essays. One area that has attracted attention in CJ studies is the optimisation of the selection of pairs of objects for judgement. One approach is known as adaptive comparative judgement (ACJ). It has been claimed in the literature that ACJ produces very high reliability, often higher than can be obtained by conventional marking. Bramley showed by simulation that adaptivity can substantially inflate the apparent reliability in ACJ. The empirical study described here compared an adaptive with a non-adaptive CJ study using GCSE English essays. An all-play-all set of comparisons of a subset of the essays allowed the extent of scale inflation to be quantified: the reported adaptive reliability was 0.97 whereas the deflated value was 0.84. The value from the non-adaptive study was 0.72. However, the scale from the non-adaptive study correlated slightly higher with external variables, suggesting the non-adaptive study was no less valid than the adaptive one.
