Le défi Un apprenant sur cinq est neurodivergent. Le matériel pédagogique classique n'a pas été conçu pour eux. Le contenu pédagogique est, par convention établie depuis longtemps, conçu autour d'un profil neurotypique restreint. Il requiert une lecture fluide, une écriture aisée, une attention soutenue pour les longs passages, ainsi que les fonctions exécutives nécessaires pour gérer des tâches comportant plusieurs étapes sans encadrement externe. Or, une grande partie des apprenants ne correspond pas à ce portrait, et c'est précisément là que ces présupposés se transforment en obstacles. Les conséquences sont bien documentées dans la littérature scientifique et visibles dans toute salle de classe : désengagement, image de soi affaiblie et accumulation de difficultés tout au long du parcours scolaire qui ne sont jamais prises en charge. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/heart-brain-white.svg) 20% Neurodivergence Dans le monde, une personne sur cinq est neurodivergente. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/dyslexia-white.svg) 15-20% Dyslexie De quinze à vingt pour cent de la population est touchée par la dyslexie. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/adhd-white.svg) 8% TDAH Environ huit pour cent des enfants sont atteints du TDAH. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/dyscalculia-white.svg) 7% Dyscalculie Autour de sept pour cent de la population est touchée par la dyscalculie.

J'ai vu beaucoup d'applications qui prétendent soutenir les apprenants autistes, pour ensuite les submerger d'animations imprévisibles et de sons aléatoires. BrainPulse est calme. L'environnement visuel est cohérent, la structure est prévisible, et mon fils sait exactement à quoi s'attendre quand il l'ouvre. Son frère l'utilise aussi, et l'expérience est différente pour lui, et c'est exactement l'idée, je crois. Maria S. Mère de jumeaux, l'un autiste et l'autre neurotypique Dyslexia " Ma fille revenait de l'école et refusait de lire quoi que ce soit. Pas parce qu'elle ne voulait pas apprendre, mais parce qu'elle était épuisée après une journée entière à lire des textes. Ça ne fonctionnaient tout simplement pas pour elle. Nous avons essayé le tutorat, mais à 65 $ l'heure pour un spécialiste, ce n'était pas viable à long terme. BrainPulse adapte la façon dont le contenu lui est présenté. Elle lit maintenant volontairement. Je ne pensais sincèrement pas voir ça cette année. Rachel W. Parent d'un enfant de 5 ans Dyscalculia " Les blocs avant la formule. C'est tout ce qu'il a fallu. Vingt-trois ans à ne pas comprendre pourquoi je n'arrivais pas à retenir les chiffres, et soudain, la structure est devenue visible. Je suis retournée lire deux chapitres que j'avais sautés il y a des années. Priya N. Chercheuse aux cycles supérieurs ADHD " Ma fille était convaincue qu'elle était simplement mauvaise à l'école. Après huit semaines, elle m'a demandé pourquoi apprendre ne lui avait jamais semblé aussi facile. Je n'ai pas su quoi lui répondre. David O. Père d'un adolescent de 14 ans Dyslexia " Pendant vingt ans, j'ai dû relire le même paragraphe trois fois avant de m'en souvenir.

Le défi Un apprenant sur cinq est neurodivergent. Le matériel pédagogique classique n'a pas été conçu pour eux. Le contenu pédagogique est, par convention établie depuis longtemps, conçu autour d'un profil neurotypique restreint. Il requiert une lecture fluide, une écriture aisée, une attention soutenue pour les longs passages, ainsi que les fonctions exécutives nécessaires pour gérer des tâches comportant plusieurs étapes sans encadrement externe. Or, une grande partie des apprenants ne correspond pas à ce portrait, et c'est précisément là que ces présupposés se transforment en obstacles. Les conséquences sont bien documentées dans la littérature scientifique et visibles dans toute salle de classe : désengagement, image de soi affaiblie et accumulation de difficultés tout au long du parcours scolaire qui ne sont jamais prises en charge. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/heart-brain-white.svg) 20% Neurodivergence Dans le monde, une personne sur cinq est neurodivergente. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/dyslexia-white.svg) 15-20% Dyslexie De quinze à vingt pour cent de la population est touchée par la dyslexie. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/adhd-white.svg) 8% TDAH Environ huit pour cent des enfants sont atteints du TDAH. ![](https://chbrainpulse.s3.ca-central-1.amazonaws.com/Icons/dyscalculia-white.svg) 7% Dyscalculie Autour de sept pour cent de la population est touchée par la dyscalculie.

J'ai vu beaucoup d'applications qui prétendent soutenir les apprenants autistes, pour ensuite les submerger d'animations imprévisibles et de sons aléatoires. BrainPulse est calme. L'environnement visuel est cohérent, la structure est prévisible, et mon fils sait exactement à quoi s'attendre quand il l'ouvre. Son frère l'utilise aussi, et l'expérience est différente pour lui, et c'est exactement l'idée, je crois. Maria S. Mère de jumeaux, l'un autiste et l'autre neurotypique Dyslexia " Ma fille revenait de l'école et refusait de lire quoi que ce soit. Pas parce qu'elle ne voulait pas apprendre, mais parce qu'elle était épuisée après une journée entière à lire des textes. Ça ne fonctionnaient tout simplement pas pour elle. Nous avons essayé le tutorat, mais à 65 $ l'heure pour un spécialiste, ce n'était pas viable à long terme. BrainPulse adapte la façon dont le contenu lui est présenté. Elle lit maintenant volontairement. Je ne pensais sincèrement pas voir ça cette année. Rachel W. Parent d'un enfant de 5 ans Dyscalculia " Les blocs avant la formule. C'est tout ce qu'il a fallu. Vingt-trois ans à ne pas comprendre pourquoi je n'arrivais pas à retenir les chiffres, et soudain, la structure est devenue visible. Je suis retournée lire deux chapitres que j'avais sautés il y a des années. Priya N. Chercheuse aux cycles supérieurs ADHD " Ma fille était convaincue qu'elle était simplement mauvaise à l'école. Après huit semaines, elle m'a demandé pourquoi apprendre ne lui avait jamais semblé aussi facile. Je n'ai pas su quoi lui répondre. David O. Père d'un adolescent de 14 ans Dyslexia " Pendant vingt ans, j'ai dû relire le même paragraphe trois fois avant de m'en souvenir.
