When it comes to describing something as "most pedagogical," there are several synonyms that can be used. Some options include: most educational, most instructive, most didactic, most informative, most enlightening, most scholarly, most academic, most intellectual, and most informative. All of these words convey the idea of something being highly focused on teaching or imparting knowledge. Depending on the context, one may be a better fit than another - for example, if something is particularly scholarly or academic, then those words may be more appropriate than simply calling it "educational." Ultimately, the choice of synonym will depend on the specific nuances and connotations that the writer wishes to convey.
