Who developed the Interaction Analysis Category System in education for increasing teacher effectiveness? Options: (a) Flander (b) Rayon (c) Amidon and Simon (d) Richard Over ✅ Correct option: (a) Flander Explanation (200+ words): The Interaction Analysis Category System (IACS) was developed by Ned A. Flanders, commonly referred to as Flanders’ Interaction Analysis (FIA). This system was introduced to study and improve teacher–student classroom interaction. It is one of the most important tools used in educational research to analyze verbal behavior in classrooms. Flanders classified classroom communication into ten categories, which include teacher talk, student talk, and silence or confusion. The primary purpose of this system is to help teachers understand how much they dominate classroom interaction and how actively students participate. Research has shown that effective teaching involves more student talk and less teacher domination. This system is especially useful in teacher training programs, micro-teaching, and classroom observation. By analyzing interaction patterns, teachers can modify their teaching strategies to make classrooms more learner-centered. Amidon and Simon also worked on interaction analysis, but the most widely recognized and used system is Flanders’. Therefore, option (a) is correct. 10 PPSC-Oriented Facts: 1.
