Abstract: Device, system, and method of adaptive teaching and learning. A computerized method includes operations performed in order to dynamically group and re-group students based on their monitored progress of interacting with digital educational learning objects; performing dynamic layout of components and elements of a digital learning object by taking into account pedagogic goals, pedagogic priorities or pedagogic significance or elements; allowing a teacher to define differential stop-lines for different groups of students; allowing a teacher to command that all student devices temporarily present a uniform learning object; allowing a content publisher to receive aggregated feedback based on monitored progress; and allowing a content publisher to package the objects as portable stand-alone playback modules.

Abstract: Device, system, and method of knowledge acquisition. For example, a system for computerized knowledge acquisition includes: a knowledge level testing module to present to a student a first set of questions in a modality at one or more difficulty levels, to receive from the student answers to said first set of questions, and to update a knowledge map of said student based on said answers; a guided knowledge acquisition module to present to the student a second set of questions in said modality, wherein the second set of questions corresponds to educational items for which it is determined that the student's performance in the first set of questions is below a threshold value; and a recycler module to present to the student an interactive game and a third set of questions in said modality, wherein the third set of questions corresponds to educational items for which it is determined that the student's performance in the first set of questions is equal to or greater than said pre-defined threshold.
