Which statement is not true about planning of teaching?

Planning of teaching refers to the deliberate preparatory decisions a teacher makes before instruction — decisions about mastering the content to be taught, framing objectives, designing feedback/assessment mechanisms, and arranging the materials and resources the lesson will need. It is a forward-looking, organisational process; it does not describe how a teacher behaves emotionally once a lesson is already underway, which is a matter of classroom conduct, not planning.

Testing each statement against "is this a preparatory decision made about teaching, in advance of the class?" shows that knowing the content to be taught, working out how students will get regular meaningful feedback, and deciding which textbooks or article copies will be needed are all preparatory decisions a teacher takes before the lesson — each is squarely part of planning. Becoming aggressive in class, however, is an emotional reaction that occurs during teaching, not a decision taken while preparing for it; it fails the test and is, in fact, the opposite of what careful planning aims to prevent.

• "Teacher should know about content" — a foundational requirement of planning: a teacher must master the subject matter before deciding how to sequence and deliver it, so this is squarely part of planning teaching.

• "Plans ways of providing regular meaningful feedback to students" — a preparatory decision about how learning will be monitored and supported, again made ahead of the lesson, so this too is planning.

• "Decide upon/order textbook(s), copies of articles, etc. which will be required" — a preparatory decision about resources needed for the lesson, so this is planning as well.

• Only "Teacher becomes aggressive in class" describes conduct during the lesson rather than a decision made while preparing for it, which is why it is the one statement that is not true about planning of teaching.
