If you are prone to thinking about instructional methods (though I realize such thought patterns are not common among most), the first things which typically come to mind are textbooks, lectures and laboratory sessions. If you are an I.S.U. forestry graduate, you may also include summer camp which is really only an extended lab session complete with picnics in the woods and dust baths in the back of the truck.
