In computing, The principle of locality of reference is the probability of a processor to repeatedly access the same set of memory locations within a small time interval. This reference of locality can be spatially based (repetitive usage of data within the same location on the computer memory), or temporally based (repetitive usage of a particular data or resources within a shot time interval). The ability of some computing system to perform this action increases their predictability, and efficiency of memory hierarchy use, among other abilities.
Have a talk with your teacher. Ask why she doesn't believe you, and if it still doesn't work, have a talk with someone that can physically help you - a principle or another teacher may be the best solution.
