This paper presents a language for courseware design that tries to overcome usability limitations shown by the Course Modeling Technique (CMT). The proposed language is able to deal with the key aspects of courseware design: objectives, contents, and instructional path. Given that its potential users are non-technical, the representation of the language is close to natural language. For its design, an emperical experimentation was made comparing its expressivity power regard to CMT. The results showed that the proposed language is more expressive and avoids some ambiguities that appears when CMT is used. Finally, the designers who participate in the tests, think that the new language is better than CMT in terms of effort required to use it.
