Train “loosely”-Means to “rMeans to “randomly” vary noncritical aspects of andomly” vary noncritical aspects of the instructional setting within and across the instructional setting within and across teaching sessionsteaching sessions- If some aspect of the materials, setting, method If some aspect of the materials, setting, method of presentation doesn’t matter, then change it of presentation doesn’t matter, then change it from time to time so the learner’s response from time to time so the learner’s response doesn’t come under control by an “irrelevant doesn’t come under control by an “irrelevant feature”feature”-this tactic often overlaps with “train sufficient this tactic often overlaps with “train sufficient exemplars” as can be seen on next slideexemplars” as can be seen on next slide
