Final answer:
Intrinsic motivation is most likely to encourage students to volunteer for activities like giving blood to the Red Cross, as it originates from within the individual and is driven by personal satisfaction, interest, or belief in the value of the task.
Step-by-step explanation:
According to self-determination theory, the type of motivation most likely to get students to volunteer to give blood to the Red Cross would be b) Intrinsic motivation. Intrinsic motivation originates from within the individual, and is driven by personal interest or enjoyment in the task itself. For instance, students might feel a personal sense of satisfaction from helping others or believe in the value of the cause, which would encourage them to volunteer.
Regarding the examples provided, Carl mowing his neighbor's yard for $20 would fall under a) Extrinsic motivation, because he is performing the task to receive monetary compensation, an external reward. Altruism, another concept in motivation, is characterized by selfless helping of others without expecting anything in return and could also drive individuals to volunteer for activities like blood donations.
Educational settings fostering a sense of belonging and respect can enhance students' intrinsic motivation to learn. An example is provided with Hakim, who is likely to experience greater intrinsic motivation in his Criminal Law course with a supportive classroom environment than in his Family Law course, which is more intimidating and evaluation-driven.
Finally, self-regulation, which can be referred to as b) will power or c) internal locus of control, denotes individuals' ability to manage their own behaviors and motivations without external reinforcement.
