Exploration Of A Confidence-Based Assessment Tool Within An Aviation Training Program, Paul F. Novacek

Journal of Aviation/Aerospace Education & Research

Traditional use of multiple-choice questions reward a student for guessing. This technique encourages rote memorization of questions to pass a lengthy exam, and does not promote comprehensive understanding or subject correlation. In an effort to identify guessing on answers during an exam within a safety-critical aviation pilot training course, a qualitative research study was undertaken that introduced a confidence-based element to the end-of-ground-school exam. Confidence-based assessments consist of students’ self-reported level of certainty in their responses, indicating which answers they believe are correct while also indicating how confident they feel with their selections. The research goals were to clearly identify …
