feedback system in Education

Young students will often look up to instructors as experts in the field and take to heart most of the things instructors say. Thus, it is believed that spending a fair amount of time and effort thinking about how to respond to students may be a worthwhile time investment. Sometimes the term "feedback" is used loosely or carelessly to refer to what is more accurately called educational reinforcement. Some general types of reinforcement that can be used in many types of student assessment are:

Confirmation	Your answer was correct.
Corrective	Your answer was incorrect. The correct answer was Jefferson.
Explanatory	Your answer was incorrect because Carter was from Georgia; only Jefferson called Virginia home.
Diagnostic	Your answer was incorrect. Your choice of Carter suggests some extra instruction on the home states of past presidents might be helpful.
Elaborative	Your answer, Jefferson, was correct. The University of Virginia, a campus rich with Jeffersonian architecture and writings, is sometimes referred to as "Mr. Jefferson's University".

A different application of feedback in education is the system for "continuous improvement" of engineering curricula monitored by the Accreditation Board for Engineering and Technology (ABET)^[15]
