Heterogeneity in Research and Practice: Perspectives of the School Pedagogy
LPL, salle de conférences B011 à 10h30 & en ligne via Zoom
(Merci de nous contacter pour obtenir l’adresse Zoom)
Résumé :
The topic of heterogeneity not only plays an important role in schools and teaching in German-speaking countries, it is also being researched worldwide. The special view that is taken in the presentation refers to cultural, social and performance-related diversity in the classroom. The school pedagogy makes a genuine contribution to pedagogical professionalism in dealing with heterogeneity for (future) teachers. Therefore, in the short presentation, some perspectives of school pedagogy on the topic will be presented and documented with own research.

Neural systems underlying auditory categorization
Abstract: My program of research uses a systems neuroscience approach to study the computations, maturational constraints, and plasticity underlying behaviorally relevant auditory signals like speech. Speech signals are multidimensional, acoustically variable, and temporally ephemeral. A significant computational challenge in speech perception (and more broadly, audition) is categorization, that is, mapping continuous, multidimensional, and variable acoustic signals into discrete, behavioral equivalence classes. Despite the enormity of this computational challenge, native speech perception is rapid and automatic. In contrast, learning novel speech categories is effortful. In this talk, I elucidate mechanisms underlying how novel speech categories are acquired and represented in the mature brain. I will demonstrate that (1) neural representations of novel speech categories can arise in the associative auditory cortex within a few hundred training trials of sound-to-category training, (2) pre-attentive signal reconstruction in the early auditory system is subject to experience-dependent plasticity, and (3) the robustness of structural and functional connectivity within a sound-to-reward cortico-striatal stream relates to learning outcome. Finally, I will discuss ongoing experiments that leverage neurobiology to design optimal behavioral training and targeted neuromodulation interventions.
About the speaker: Dr. Chandrasekaran serves as a Professor and Vice Chair of Research in the Department of Communication Sciences and Disorders at The University of Pittsburgh. He earned his Ph.D. in Integrative Neuroscience from Purdue University in 2008, completed a postdoctoral fellowship at Northwestern University before joining the University of Texas at Austin in 2010. He is the recipient of Regents’ Outstanding Teaching Award in 2014, the Editor’s award for best research article in the Journal of Speech, Language, and Hearing Research, the Psychonomics Early Career award in 2016, and the Society for Neurobiology of Language Early Career Award in 2018. Dr. Chandrasekaran has served as the Editor-in-Chief of the Journal of Speech, Language, and Hearing Research (Speech). Over the last two decades, his lab has leveraged cutting-edge multimodal neuroimaging methods and computational modeling approaches to develop a sophisticated understanding of how sounds are represented and categorized in the human brain. His approach is highly collaborative and interdisciplinary, integrating across fields of communication sciences and disorders, neuroscience, linguistics, psychology, engineering, and otolaryngology. His laboratory is currently supported by funding from the National Institutes of Health (NIH) and the National Science Foundation (NSF).
Séminaire SYSTUS : Autour de la Grande Grammaire du Français
Vendredi 8 avril 2022 – 10h30-12h30 – Salle B 011
10h30-11h30 : Anne Abeillé, Université de Paris
« La grande grammaire du français : un livre et un projet hors norme »
Anne Abeillé a co-dirigé l’ouvrage avec Danièle Godard, en collaboration avec Annie Delaveau et Antoine Gautier. Ce projet a reçu le soutien de la Fédération ILF du CNRS, de la DGLFLF, de l’Université Paris 7 et du LabEx EFL. La grammaire est organisée en vingt chapitres, et est sortie, en version papier (2 volumes) et en version numérique, aux éditions Actes Sud / Imprimerie Nationale le 6 octobre 2021. Ce projet a impliqué une cinquantaine de linguistes, de nationalités diverses, d’une trentaine d’universités et laboratoires en France et ailleurs. Une de ses ambitions est de présenter de façon cohérente (et lisible pour un large public) les avancées dans la connaissance de la syntaxe du français et de ses interfaces avec le lexique, la sémantique, le discours et la prosodie. Une autre est de prendre en compte la variation des données, en s’intéressant à des données régionales (décrites) et orales (grâce à l’interrogation de corpus oraux). La version numérique permet l’écoute de nombreux exemples oraux.

« Sur les rapports entre données linguistiques et description syntaxique : l’exemple des relatives en où en français parlé »
Les relatives en où (le jour où il viendra) ont donné lieu à de minutieuses études de syntaxe et de sémantique, mais il manque à ce jour un bilan sur les usages attestés en français parlé contemporain. En particulier, nous évoquerons certains emplois minoritaires attestés dans les corpus, en nous interrogeant sur les relations entre les données linguistiques et leur description grammaticale.
12h-12h30 : Discussion autour des systèmes et des usages
