  • Publication number: 20140120514
    Abstract: A cloud learning system capable of enhancing learner's capability based on then-current contour or profile of levels or capabilities of the learner provides tests about a subject, a skill or expertise in advance to determine then-current contour or profile of capability of the test-taker. Then learning data or material is provided to a user for training, while the learning data or material is based on the test points or formats for the test implicitly or explicitly, contained or hidden in the test questions so as to enhance some weak areas of the user detected or diagnosed in the test. The capability of the learner is enhanced and the user has higher confidence to learn the subject, the skill or the expertise further. The structure can be constructed in a cloud network structure. External content-providers can provide their teaching material to the dedicated database based on specific test points or formats.
