Social justice in education : how the function of selection in educational institutions predicts support for (non)egalitarian assessment practices
Educational institutions are considered a keystone for the establishment of a meritocratic
society. They supposedly serve two functions: an educational function that promotes learning
for all, and a selection function that sorts individuals into different programs, and ultimately
social positions, based on individual merit. We study how the function of selection relates to
support for assessment practices known to harm vs. benefit lower status students, through the
perceived justice principles underlying these practices. We study two assessment practices:
normative assessment-focused on ranking and social comparison, known to hinder the
success of lower status students-and formative assessment-focused on learning and
improvement, known to benefit lower status students. Normative assessment is usually
perceived as relying on an equity principle, with rewards being allocated based on merit and
should thus appear as positively associated with the function of selection. Formative
assessment is usually perceived as relying on corrective justice that aims to ensure equality of
outcomes by considering students' needs, which makes it less suitable for the function of
selection. A questionnaire measuring these constructs was administered to university students.
Results showed that believing that education is intended to select the best students positively
predicts support for normative assessment, through increased perception of its reliance on
equity, and negatively predicts support for formative assessment, through reduced perception
of its ability to establish corrective justice. This study suggests that the belief in the function
of selection as inherent to educational institutions can contribute to the reproduction of social
inequalities by preventing change from assessment practices known to disadvantage lowerstatus
student, namely normative assessment, to more favorable practices, namely formative
assessment, and by promoting matching beliefs in justice principles
Reproduction of social class inequalities at school: experimental study of structural barriers to educational equality
Belief in School Meritocracy and the Legitimization of Social and Income Inequality
Educational institutions are imbued with an institutional meritocratic discourse: only merit counts for academic success. In this article, we study whether this institutional belief has an impact beyond its primary function of encouraging students to study. We propose that belief in school meritocracy has broader societal impact by legitimizing the social class hierarchy it produces and encouraging the maintenance of inequalities. The results of four studies (one correlational study, Ntotal = 198; one experiment, Ntotal = 198; and two international data surveys, Ntotal = 88,421 in 40+countries) indicate that belief in school meritocracy reduces the perceived unfairness of social class inequality in society, support for affirmative action policies at university and support for policies aimed at reducing income inequality. Together, these studies show that the belief that schools are meritocratic carries consequences beyond the school context as it is associated with attitudes that maintain social class and economic inequality
Teaching as Social Influence: Empowering Teachers to Become Agents of Social Change
International audienceTeachers carry out a number of roles in the educational system. Their primary role is to help all students develop knowledge and skills, but, most of the time, they take on the role of gatekeepers: They evaluate students and exercise selection on the basis of performance. We analyze the roles of teachers through the lens of the literature on social influence, and put forward the proposal that teaching is a form of social influence. We review existing research on the mechanisms that explain the differential effects teachers may have on students' learning, students' prospects and, therefore, educational justice. We conclude that if teachers endorse the role of mentors-instead of that of gatekeepers-focusing on the development of their students' knowledge, they can promote deep study, long-term learning, and equality of treatment. Such an approach could help design teacher training and school reform so as to maximize the learning potential of all students and empower teachers to become active agents of profound individual and social change
The function of selection of assessment leads evaluators to artificially create the social class achievement gap.
To understand the persistent social class achievement gap, researchers have investigated how educational settings affect lower vs. higher socio-economic status (SES) students’ performance. We move beyond the question of actual performance to study its assessment by evaluators. We hypothesized that even in the absence of performance differences, assessment’s function of selection (i.e., compare, rank and track students) leads evaluators to create a SES achievement gap. In two experiments (N = 196; N = 259), participants had to assess a test supposedly produced by a high- or a low-SES student, and used assessment for selection (i.e. normative grading) or learning (i.e. formative comments). Results showed that evaluators using assessment for selection found more mistakes if the test was attributed to a low- rather than a high-SES student, a difference reduced in the assessment for learning condition. The third and fourth experiments (N = 374; N = 306) directly manipulated the function of assessment to investigate whether the production of the social class achievement gap was facilitated by the function of selection to a greater extent than the educational function. Results of Experiment 3 supported this hypothesis. The effect did not reach significance for Experiment 4, but an internal meta-analysis confirmed that assessment used for selection led evaluators to create a SES achievement gap more than assessment used for learning, thereby contributing to the reproduction of social inequalities
School Selection and the Social Class Divide: How Tracking Contributes to the Reproduction of Inequalities
International audienceSelection practices in education, such as tracking, may represent a structural obstacle that contributes to the social class achievement gap. We hypothesized that school’s function of selection leads evaluators to reproduce social inequalities in tracking decisions, even when performance is equal. In two studies, participants (students playing the role of teachers, N = 99, or preservice and in-service teachers, N = 70) decided which school track was suitable for a pupil whose socioeconomic status (SES) was manipulated. Although pupils’ achievement was identical, participants considered a lower track more suitable for lower SES than higher SES pupils, and the higher track more suitable for higher SES than lower SES pupils. A third study (N = 160) revealed that when the selection function of school was salient, rather than its educational function, the gap in tracking between social classes was larger. The selection function of tracking appears to encourage evaluators to artificially create social class inequalities
Clinical and Immunologic Effects of Paraprobiotics in Long-COVID Patients
Background and objectives
After the enormous health burden during the acute stages of the COVID-19 pandemic, we are now facing another important challenge, that is, long-COVID, a clinical condition with often disabling signs and symptoms of the neuropsychiatric, gastrointestinal, respiratory, cardiovascular, and immune systems. While the pathogenesis of this syndrome is still poorly understood, alterations of immune function and the gut microbiota seem to play important roles. Because affected individuals are frequently unable to work for prolonged periods and suffer numerous health compromises, effective treatments represent a major unmet medical need. Multiple potential therapies have been tried, but none is approved yet. Approaches that are able to influence the immune system and gut microbiota such as probiotics and paraprobiotics, i.e., nonviable probiotics, seem promising candidates. We, therefore, evaluated the clinical and immunologic effects of paraprobiotics in a small pilot study.
Methods
A total of 6 patients with long-COVID were followed systematically for more than 12 months after disease onset using standardized validated questionnaires, a smartphone app, and wearable sensors to assess neurocognitive function, fatigue, depressiveness, autonomic nervous system alterations, and quality of life. We then offered patients defined paraprobiotics for 4 weeks and evaluated them at the end of the treatment period using the same questionnaires, smartphone app, and wearable sensors. In addition, a comprehensive immunophenotyping and gut microbiota analysis was performed before and after treatment.
Results
Improvements in several of the neurologic symptoms such as dysautonomia, fatigue, and depression were documented using both patient-reported outcomes and data from the smartphone app and wearable sensors. Of interest, the expression of activation markers on some immune cell populations such as B cells and nonclassical monocytes and the expression of toll-like receptor 2 (TLR2) on T cells were reduced after paraprobiotics treatment.
Discussion
Our results suggest that paraprobiotics might exert positive effects in patients with long-COVID most likely by modulating immune cell activation and expression of TLR2 on T cells. Further studies with paraprobiotics should confirm the promising observations of this small pilot study and hopefully not only improve the outcome of long-COVID but also unravel the pathomechanisms of this condition.
Classification of evidence
This study provides Class IV evidence that paraprobiotics increase the probability of favorable changes of clinical and immunologic markers in patients with long-COVID
Après la Note : Effets Psychosociaux de L'Evaluation Normative
L’évaluation n’est pas un exercice neutre qui consiste à quantifier les mérites de la production d’un élève : selon le type d’évaluation utilisée (p.ex., normative ou formative) et selon la fonction qu’on lui attribue (sélectionner ou former), les élèves se sentent plus ou moins menacés, et développent des représentations différentes de leur autonomie et de leurs compétences sociales. Ceci a un impact sur leur apprentissage et sur l’égalité de chances. Le présent chapitre passe en revue un programme de recherche qui étudie la menace impliquée dans l’évaluation normative et ses conséquences en termes d’autonomie, compétences sociales et inégalité de traitement des élèves
Identification of brain-enriched proteins in the cerebrospinal fluid proteome by LC-MS/MS profiling and mining of the Human Protein Atlas
BACKGROUND: Cerebrospinal fluid (CSF) is a proximal fluid which communicates closely with brain tissue, contains numerous brain-derived proteins and thus represents a promising fluid for discovery of biomarkers of central nervous system (CNS) diseases. The main purpose of this study was to generate an extensive CSF proteome and define brain-related proteins identified in CSF, suitable for development of diagnostic assays. METHODS: Six non-pathological CSF samples from three female and three male individuals were selected for CSF analysis. Samples were first subjected to strong cation exchange chromatography, followed by LC-MS/MS analysis. Secreted and membrane-bound proteins enriched in the brain tissues were retrieved from the Human Protein Atlas. RESULTS: In total, 2615 proteins were identified in the CSF. The number of proteins identified per individual sample ranged from 1109 to 1421, with inter-individual variability between six samples of 21 %. Based on the Human Protein Atlas, 78 brain-specific proteins found in CSF samples were proposed as a signature of brain-enriched proteins in CSF. CONCLUSION: A combination of Human Protein Atlas database and experimental search of proteins in specific body fluid can be applied as an initial step in search for disease biomarkers specific for a particular tissue. This signature may be of significant interest for development of novel diagnostics of CNS diseases and identification of drug targets.
