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.

15. The system of claim 2, wherein the interactive game presented by the recycler module comprises a game selected from the group consisting of:

a memory game, a matching game, a spelling game, a puzzle game, and an assembly game.

16. The system of claim 2, wherein the interactive game presented by the recycler module comprises a combined list of vocabulary words, which is created by the recycler module based on:

a first list of vocabulary words that the student mastered in a first time period ending at the creation of the combined list of vocabulary words, and a second list of vocabulary words that the student mastered in a second time period ending prior to the beginning of the first time period.

17. The system of claim 16, wherein the recycler module is to create said combined list of vocabulary words based on:

the first list of vocabulary words sorted based on respective recycling counters, and the second list of vocabulary words sorted based on respective recycling counters.
