A computer system that may, for example, be used for educational purposes delivers content, e.g., instructional content, to a plurality of users, e.g., students. The content is presented to such users in units, e.g., learning units. Each unit has associated with it an assessment information relating to each one of the users. One or more systems, e.g., learning systems, present the one or more units to one or more users in a first interactive environment, e.g., a first learning environment, and a second interactive environment, e.g., a second learning environment, that is different from the first interactive environment. A digital rights and asset management application controls access to the content associated with each one of said one or more units according to corresponding unit identifiers, e.g., learning unit identifiers, and presents such content to the plurality of users in the first and second interactive environments for assessment purposes. An assessment application, e.g., a grade book application, stores assessment information derived from presenting the content to said one or more users in the first and second interactive environments, with the unit identifier correlating the assessment information with the units.
