WeLearnedIt is an excellent free iPad app for the mobile classroom, E-portfolios, and project based learning. This is a state of the art learning system that allows educators to create classes, add students, and then create assignments (containing video, audio, images, etc) and digital portfolios. Also, an educator generate detailed reports, grade/assess students, and interact completely w/ eduClipper. WeLearnedIt is contained in a safe environment and invite students to join classes via a unique code. Best of all, are the abundance of features that a an educator has from setting permissions, to leaving comments, and much much more.
