Abstract

L'invention concerne un procédé et un système d'enregistrement et de demande d'enseignement de salle de classe, destinés à mieux réviser le cours et à consolider l'apprentissage. Le procédé comprend les étapes suivantes : pendant l'enregistrement d'un cours, segmenter des données d'enseignement de salle de classe enregistrées grâce à des identifiants d'horodatage, chaque segment de données d'enregistrement correspondant à au moins un point clé d'explication de salle de classe correspondant ; ajouter une question correspondant à chaque point de clé d'explication de salle de classe après l'enregistrement de chaque segment de données de l'enseignement de salle de classe ou après l'enregistrement complet de l'enseignement de salle de classe ; de plus, établir la corrélation entre chaque point clé d'explication de salle de classe et chaque question de test de devoirs ou d'interrogation surprise, et construire une base de données de corrélation en fonction des corrélations entre le point clé d'explication de salle de classe, et les données d'identifiant de segmentation, la question et la question de test, de sorte que, lorsqu'un étudiant demande le cours de salle de classe enregistré en ligne, après la visualisation d'un segment ou de tout le contenu, si l'étudiant rencontre des difficultés lors de la réponse à chaque question ou question de test, l'étudiant est capable d'obtenir une révision et une consolidation d'apprentissage du cours de salle de classe enregistré extrêmement efficaces en révisant uniquement un segment correspondant des données enregistrées grâce à la corrélation entre le point clé et les données d'identifiant de segmentation.
