History shows reiteratively throughout the recorded times that the mark set for students will be predominately that which they aim for and mostly stop therein. If students are not shown any higher level of knowledge the students should at no time be expected to aim for that which they did not perceive. Students will indeed float to the mark you set. History has shown us many valuable illustrations; one of them would be the vast comparison between students during the Ottoman empire and students in the reign of the Spartan empire, the Spartans were taught that knowledge is crucial, if it helps you to fight, whilst the Ottomans were taught that knowledge was imperative if it was beneficial in any way. Because Spartan pupils were finite to knowledge that did not pertain to warfare, they were infinitesimally limited in any other area, and to no degree were able to match the heights of knowledge of the Ottoman student body, the mark for these learners had been set considerably inferior than that for the under-graduates of the Ottoman empire, and so the students attained the mark that was set and were prescribed no reason to surpass it.
Therefore it is clear to recognize that the objective a teacher sets for their pupil is all that their pupil will ever feel the demand to accomplish. Students are comparable to a kayak in the sea trying to reach an island to anchor on, and the teacher is the equivalent of the current, the stronger they push to try to reach and help the students, the closer they get to the island. Because students are reliant on their instructors to provide them with an objective to grasp, the supervisors specified a mark, and the students float to the mark that was decided. Therefore the students need only fulfill that which their instructor has itemized for them, and that would be the mark that was stipulated. Since pupils will only feel the need to do what was required in distinction to them, they will inevitably isolate themselves to the mark that was set before them.
