Abstract: Adaptive teaching and learning utilizing smart digital learning objects. For example, a system for adaptive computerized teaching includes: a computer station to present to a student an interactive digital learning activity based on a structure representing a molecular digital learning object which comprises one or more atomic digital learning objects, wherein at least one action within a first of the atomic digital learning objects modifies performance of a second of the atomic digital learning objects.

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.

Abstract: The invention relates to a method for visually presenting a set of properties of a web site, which comprises: (a) predefining within a provider's search engine a set of properties and assigning to each property a visual symbol; (b) using a spider program, visiting by said provider's search engine each web site and determining those properties from said set that are characteristic to that web site; (c) associating by said provider's search engine with each web site those symbols corresponding to said determined properties; (d) forming for each web site a corresponding combined visual representation of the web site based on said associated symbols; and (e) when listing search results to a user, including the combined visual representation for each web site respectively.

Abstract: Device, system, and method of adaptive teaching and learning. For example, a teaching/learning system includes a real-time class management module to selectively allocate first and second digital learning objects for performance, substantially in parallel, on first and second student stations, respectively.
