Control and constraint in e-learning; choosing when to choose.9781599043906Control and constraint Constraint A restriction on the natural degrees of freedom of a system. If n and m are the numbers of the natural and actual degrees of freedom, the difference n - m is the number of constraints. in e-learning (Electronic-LEARNING) An umbrella term for providing computer instruction (courseware) online over the public Internet, private distance learning networks or inhouse via an intranet. See CBT. ; choosing when to choose. Dron, Jon. Information Science Publishing 2007 340 pages $94.95 Hardcover LB1044 Dron (computing computing - computer , mathematical, and information sciences, U. of Brighton, UK) considers the way that individuals learn and specifically how an online learning environment can affect the learning path. He describes how networked learning environments should be constructed to give control to learners, and synthesizes theories about learner control, autonomy, self-direction, adult leaning, and other concepts into a single theory of transactional control from a systems perspective. The book is intended for educators and others interested in theory of e-learning, creators, facilitators, and developers, with each section directly relating to relating to relate prep → concernant relating to relate prep → bezüglich +gen, mit Bezug auf +acc these groups. The first puts forth a framework for understanding educational systems in terms of choice and constraint, and how to view them from different perspectives. This is followed by application of the framework to e-learning situations and modes, such as electronic publication, assisting learners in finding resources, asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. and synchronous Refers to events that are synchronized, or coordinated, in time. For example, the interval between transmitting A and B is the same as between B and C, and completing the current operation before the next one is started are considered synchronous operations. Contrast with asynchronous. discussion, and integrated environments. The book ends with a section on designing social software, Web 2.0, types that use the author's principles, and possible problems. It does not cover how adults learn or transactional control in terms of database management. ([c]20072005 Book News, Inc., Portland, OR) |
