Fri, 05 Sep 2008 18:02:49 GMT http://www.ruleworks.co.uk/mobat/learning-style.htm The preferred trainee learning style and learning modes are considered a separate part of a trainee profile. Fri, 05 Sep 2008 18:02:07 GMT http://www.ruleworks.co.uk/mobat/trainee-profile.htm The trainee profile is basically a record of a trainee knowledge and a static database. Fri, 05 Sep 2008 18:01:09 GMT http://www.ruleworks.co.uk/mobat/target-audience.htm The target audience for the training application has to be determined.

Fri, 05 Sep 2008 17:55:56 GMT http://www.ruleworks.co.uk/mobat/using-models.htm Methods are presented in this section which provide a consistent way in how the trainer agent is using the multiple modelling dimensions. Fri, 05 Sep 2008 17:55:05 GMT http://www.ruleworks.co.uk/mobat/model-uncertainty.htm The uncertainty of a model can be expressed by the belief or confidence in the chosen description of training properties in the subject domain. Fri, 05 Sep 2008 17:54:20 GMT http://www.ruleworks.co.uk/mobat/model-accuracy.htm For each concept hierarchy in Workmanship-MOBAT, the training system can determine an appropriate range.
