Which of the following teacher responses could be considered inadequate?

The response "That's right - toys" can be considered inadequate because it lacks depth and does not foster further thought or engagement from the student. While it acknowledges the student's correct answer, it does not encourage the student to elaborate or expand on their understanding of the topic. Effective teaching often involves prompting students to think critically, articulate their reasoning, and explore concepts more deeply. Responses that invite further discussion or require the student to explain their thinking (like asking for an explanation or soliciting their opinion) promote a more interactive and thoughtful learning environment. In contrast, simply affirming an answer does not provide opportunities for deeper learning or assessment of the student's grasp of the subject matter.
