Argumentation at the table-talk level of middle school students participating in scientific cafés
Résumé
"Scientific café" refers to the public discussion of socially pertinent questions which have scientific content in an informal setting, typically a bar. This scheme has been adapted to middle and high school class settings. This paper presents an experimental organizational scheme which uses electronic voting. The scheme is evaluated with respect to student engagement and participation, as well as the relationship between the preliminary, private discussion in the small groups and students' public space interventions.
