My students are taught to use substitution only when the integration problem seems to be too complicated or to simplify problems which have radicals. I direct them to recognize the use of integration by parts when there is a variable which will reduce to a constant after taking the derivative of it one or more times orif there are functions whose derivatives are of a cylic nature such as cosine, sine, or exponential functions, then they are directed towards integration by parts.
