Comment la science représente-t-elle le réel ? (audio)

Le mot de représentation évoque tout d'abord la présence d'une image, une image qui est directement accessible au sens. Le contenu de cette image propose un double de l'objet ou de l'événement saisi dans une expérience effective. La représentation scientifique peut utiliser des images comme support et auxiliaire de pensée de ces objets, mais ce n'est pas en tant qu'image qu'elle en construit des représentations.

A Study of the Prereferral Intervention Process in Pennsylvania Following the Rescinding of the Inst
The increasing demand for special education services has been identified as a major contributor to the rising cost of education, and frequently students are erroneously identified as requiring special education services when their needs could be adequately addressed in the regular education classroom. The prereferral intervention process has been proposed as an alternative to the traditional refer-test-place process of identifying special education students because struggling students receive ex

The Rhetorical Situations of College Writing Assessment: Exigence, Constraints and Audience in the E
While literacy educators in the field of composition studies have traditionally approached the issue of writing assessment from a classroom perspective that emphasized assessment’s role in the processes of teaching and learning, recent trends in American public policy have made data gathered from educational assessment the basis for arguments of education policy reform. In particular, during the past 15 years, a loose affiliation of advocacy groups known as the P-16 movement has sought to use

This qualitative study explored student and teacher perceptions and instructional approaches in a university research writing course, seeking clues to student engagement. Data collecti

Judging the Hate Crime Victim: Law School Student Perceptions and the Effects of Individual and law
The present study examines the effects of individual and law school factors on the perceptions of African-American, gay, and lesbian hate crime victims for 283 law school students from two schools in western Pennsylvania. Although research on the perceptions of hate crimes and hate crime victims has increased over the last decade, research has neglected to focus on this particular population of students. This population is important because many of these law students will seek roles in the crimi

The majority of our nation‟s academic institutions fall short in their efforts to ensure that African American students successfully persist from admission to graduation. Since the majority of African American students attend Predominately White Institutions (PWIs), these institutions must be held to the highest standard of accountability for African American student retention. Therefore, PWIs must explore alternative retention mechanisms that will increase the African American student‟s int

The recent focus on Response to Intervention (RTI) has heightened the need for information regarding characteristics of prereferral intervention teams (PITs) that lead to successful outcomes. Though many researchers have theorized about important features of PITs, few studies have examined the factors that lead to high-functioning teams. Elementary principals in Pennsylvania (N = 440) were surveyed regarding prereferral intervention practices. Schools that continued to employ instructional
