Academisms refer to the principles or methods of academic study, typically characterized by a formal, structured approach. However, there are several antonyms that describe alternative ways of learning or knowledge acquisition. One antonym for academisms is "practicality," which emphasizes the importance of tangible skills and experiential knowledge over purely theoretical knowledge. Another antonym is "informality," which is characterized by a more relaxed, flexible approach to learning, and favors real-life experiences over traditional classroom-based instruction. "Anti-intellectualism" is another antonym for academisms, often associated with skepticism towards experts and formal education. Finally, "dilettantism" refers to a lack of commitment or expertise in a particular subject, often associated with amateurish, superficial knowledge.
