Online tests based on contributions provided by teachers and students during face-to-face lectures

National audienceOur previous work has introduced the "Tsaap-Notes" platform to increase the motivation and engagement of students in the process of collaborative note taking during lectures. In this paper, we introduce the approach "Notes as Feedback" which consists of recycling interactive questions asked during a lecture in order to semi-automatically build computer based self-assessment tests where feedback provided to students is based on the notes taken by students. A first experimentation on a group of 54 students enrolled in a computer science Master course helped to highlight the benefits of this work: increased participation in note-taking, a massive engagement of students to play the self-assessment tests, and improved student results at the final exam

Tsaap-Notes -- An Open Micro-Blogging Tool for Collaborative Notetaking during Face-to-Face Lectures

International audienceSocial theories of learning demonstrated that collaborative note taking during face-to-face lecture provides important benefits: better learner engagement, collaborative learning, and knowledge building. In this paper we present Tsaap-Notes, an open micro-blogging platform dedicated to collaborative note taking that can be used as a standalone application, or fully integrated into existing virtual learning environments. Tsaap-Notes provides users with advanced features such as annotations, questions, or filtering that encourage learners to participate in the collaborative activity. Our tool has been experimented with a cohort of forty students during a short period of time, results show that learners are getting more and more familiar with Tsaap-Notes and that this application becomes useful when the time of preparing exams has come

Génération semi-automatique de tests d'auto-évaluation pourvus de feedback résultant de la prise de notes collaborative

International audienceNos travaux prédécents ont introduit la plate-forme Tsaap-Notes pour augmenter la motivation et l'engagement des étudiants dans le processus de prise de notes collaborative pendant les cours dispensées en face-à-face. Dans cet article, nous introduisons l'approche « Notes as Feedback » consistant à recycler les questions interactives posées pendant le cours afin de produire semi-automatiquement des tests d'auto-évaluation informatisés pourvus de feedback issus des notes prises par les étudiants. Une première expérimentation réalisée sur un groupe de 54 étudiants inscrits en Master Informatique a permis de mettre en avant les bénéfices de ces travaux : une participation accrue à la prise de notes collaborative, un engagement significatif des étudiants dans les tests de révision, et des résultats en hausse à l'examen terminal

Tsaap-Notes : Plateforme de prise de notes collaborative étendue

Plusieurs études ont montré les bénéfices apportés par les systèmes de prise de notes collaborative, les systèmes de micro-blogging et les systèmes de votes interactifs dans différents contextes d'apprentissage. Dans cet article, nous nous intéressons plus particulièrement au contexte des cours dispensés en face à face à un grand nombre d’étudiants. Nous présentons Tsaap-Notes, une plate-forme de prise de notes collaborative reposant sur un système de microblogging et intégrant les fonctionnalités de systèmes de votes interactifs. Tsaap-Notes combine les fonctionnalités des trois systèmes afin d’améliorer et de renforcer les bénéfices qu’apportent chacun des systèmes pris séparément. L’article présente également les résultats encourageants provenant d'une première expérimentation réalisée avec un groupe de quarante étudiants

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.
