“Newcomers to Wikipedia may not understand that discussion about what gets added or deleted from entries isn’t done behind closed doors. Rather, it happens on the publicly accessible “notes” pages of each entry—where volunteers will discuss edits and have open discussions on whether changes should go forward or not. Editing Wikipedia pages helps users understand just how malleable knowledge is, says Alex Jung, the University of Toronto’s Wikipedian-in-residence. If someone makes substantive edits to an entry, “someone who visited the page today will have an entirely different idea of the topic than someone who visited it yesterday. Knowledge is fluctuating all the time.””

“In apps marketed for children 5 and under in the Google Play store, there were pop-up ads with disturbing imagery. There were ads that no child could reasonably be expected to close out of, and which, when triggered, would send a player into more ads. Dancing treasure chests would give young players points for watching video ads, potentially endlessly. The vast majority of ads were not marked at all. Characters in children’s games gently pressured the kids to make purchases, a practice known as host-selling, banned in children’s TV programs in 1974 by the Federal Trade Commission. At other times an onscreen character would cry if the child did not buy something. “The first word that comes to mind is furious,” said Dr. Radesky, an assistant professor of developmental behavioral pediatrics at the University of Michigan Medical School.”

« If we do not change the way we teach, thirty years from now we will be in trouble » – Jack Ma (Alibaba Group).

«Bien que la désinformation soit clairement un problème, son échelle et son influence, ainsi que ceux qui la propagent et l’amplifient n’ont pas été suffisamment étudiés ou examinés. Sans cette base empirique, aucune action concrète ne devrait être prise au-delà d’autres initiatives de recherche et d’éducation, à condition qu’elles soient clairement évaluées».

«Une autre expérimentation consiste à mesurer en temps réel le niveau d’attention des élèves en les filmant dans la classe avec deux caméras. Tous les professeurs perdent à un ­moment donné l’attention de leur auditoire. Certains s’en rendent compte et réagissent : ils modifient par exemple le tempo de leur voix ou mentionnent que le sujet sera au programme du prochain contrôle. D’autres ne prennent pas conscience qu’ils ont perdu l’attention des élèves, parce qu’ils regardent seulement ceux du premier rang, qui suivent bien. Et, donc, on peut envisager d’envoyer une alerte à ce professeur sur son smartphone pour l’informer qu’il n’a plus que 10 % d’étudiants attentifs à son cours».

Science professor Wei Xiaoyong developed the new “face reader” to identify emotions which suggest if students are bored or stimulated.His technique produces a “curve” for each student showing how much they are either “happy” or “neutral”, and that data can indicate whether they are bored, he said.“When we correlate that kind of information to the way we teach, and we use a timeline, then you will know where you are actually attracting the students’ attention,” Professor Wei told The Telegraph.
