Since you want information on the elements of motivation and you've presented (almost) the three-part model of motivation, let me just clarify it for you a bit first. As litteacher states, and according to Virginia Commons University, the key elements of the three-part model of motivation are:
These elements answer the questions of "What?" "How much?" and "How long?" Please note: the model only enunciates the "What?" question but as a comprehension and memory aid, iit is helpful to some to also phrase the other two elements in terms of related questions as well.
Direction is the choice for decision or action that is made out of the various alternatives available: What will you choose do to address the problem, the project, the issue, the need? Intensity is with how much energy and vigor you work in fulfilling the choice of decision or action you have made: How much effort will you expend? How much energy will you devote? Persistence is how long a duration you will expend effort and energy on the action or decision you make: How long will you expend effort and energy? How long a duration of time will you put effort and energy into the action or decision?
It is important to remember that motivation models predict effort, not outcome: motivation facilitates choosing a direct to go, expending intensity of energy and effort, and persistence in continuing to expend energy and effort. It does not facilitate outcome except insofar as direction of action, intensity of effort and persistence in exertion relate to outcome. In addition, motivation may be multifaceted--have more than one direction of exertion--because motivation may stimulate a response to more than one need: each need may require a unique direction and a different effort over varying durations; thus motivation may be multifaceted.
