A study points to the possibility that students are learning more under adjuncts than regular professors.Ad­juncts Are Bet­ter Teachers Than Tenured Professors, Study FindsThere may be several explanation for adjuncts' performances that I can think of:1) they are teaching from a narrower scope of knowledge, and therefore don't go off on many peripheral or exceptional theories as higher professors2) because of job insecurity, they feel the need to maintain higher levels of student learning and satisfaction so they will be hired the next semester3) they are not part of "university politics" and therefore can dedicate more time to teaching rather than committees or other concerns4) because of higher turnover, new adjuncts get into teaching more frequently than established professors, creating a fresher perspective for students compared to faculty who have been teaching courses for 20+ years5) adjuncts may generally be younger in age than professors, meaning they are more in tune with how college students learn in today's age
