There are a number of synonyms that can be used in place of "is taught." For example, "is instructed," "is trained," "is educated," and "is coached" all convey the same basic meaning. Other options include "is mentored," "is tutored," "is guided," and "is shown." Each of these synonyms carries a slightly different connotation, so the choice of which to use depends on the context of the sentence and the effect the writer or speaker wishes to achieve. Ultimately, the important thing is to vary one's vocabulary and avoid repeating the same phrase over and over again.
