1. A method for constraining learning strategies for a training course, comprising: presenting, to an author of a training course, a plurality of selectable concepts available for generating a training course; receiving, from the author, a selection of at least a subset of the plurality of selectable concepts to include in the training course; determining a plurality of learning strategies available for the training course based, at least in part, on the selected subset of concepts, each of the plurality of learning strategies define different sequences through the selected subset of concepts; presenting, to the author of the training course, the plurality of learning strategies for the training course defining the different sequences; reducing, by the author, the different sequences through the selected subset of concepts to a subset of different sequences, wherein learners are limited to progressing through the subset of the selectable concepts by the subset of different sequences; and presenting, to learners, the training course having selectable learning strategies limited to the subset of different sequences.
