Some students in your class have a negative attitude towards mathematics. What…

A core principle of teaching aptitude is that a professionally sound response to a student's negative attitude or disengagement from a subject is constructive and instructional: the teacher reflects on and adapts their own teaching approach rather than blaming, avoiding, or ignoring the learner. A negative attitude is treated as a signal to review pedagogy — methods, pacing, relevance, and engagement — not as a fixed trait of the student.

Applied here: some students dislike mathematics, so the constructive, professional response is to improve teaching methods — make lessons more relatable, engaging, and suited to how these students learn. This directly targets the pedagogical root of the negativity.

Checking against each alternative confirms this is the only option that fits:

• Turning away from disappointed students avoids the problem instead of solving it and is unprofessional — it does nothing to change how the students feel about the subject.

• 'Subtle to gross' is a genuine principle about the order in which content is introduced within a topic — a different concern from why a class dislikes the subject, so it does not describe an action addressing this scenario.

• Asking the students to 'set new dimensions' is likewise not a concrete teaching action, so it cannot be the response that resolves the disengagement.

So improving teaching methods is the answer — it is the only option that is both constructive and directly targets the cause of the students' negative attitude.
