6-13  Chapter Summary  This chapter described the methods and techniques aviation instructors use to assess learner progress. A well-designed and timely  assessment defines what is worth knowing, enhances motivation, and improves learning. Today’s learners want to know the criteria  by which they are assessed, and they want practical and specif i c feedback. Aviation instructors familiar with different  types of assessments know how and when to use them to promote a productive learning environment . Each situation a learner faces may not have one right, and one wrong answer. Instead, learners will encounter situations in training  that may have several "good" outcomes as well as the potential for some "poor" ones. While the  f light  i nstructor should understand in  advance which outcomes are positive or negative, the instructor allows the learner to make both good and poor decisions. This does  not mean that the learner should be allowed to make an unsafe decision or commit an unsafe act. However, it does allow the learner to  make decisions that fit their experience level and result in positive outcomes.
