Which one of the following is not related to Flander’s interaction analysis…

Flanders' Interaction Analysis Categories System (FIAC), developed by Ned A. Flanders, is a classroom-observation technique that codes verbal classroom interaction, every three seconds, into ten categories grouped under three broad heads: Teacher Talk, Student Talk, and Silence or Confusion.

Mapping each option against Flanders' ten categories:

• Teacher talk falls under the seven Teacher Talk categories (categories 1-7), covering things like questioning, lecturing, giving directions, and using students' ideas.

• Student talk falls under the two Student Talk categories (categories 8-9): student-talk-response and student-talk-initiation.

• Silence is explicitly category 10 of the scheme, covering pauses or periods of confusion during observation.

• Guardian talk has no category in this ten-category scheme, since Flanders built the instrument to record only verbal exchange occurring inside the classroom between teacher and students.

Cross-check: because every one of Flanders' ten categories describes classroom-internal teacher or student speech (or silence), any interaction that occurs outside that boundary -- such as a teacher's conversation with a guardian -- cannot belong to the scheme, confirming which option falls outside Flanders' interaction analysis system.
