Which of the following does not support teaching according to individual…

Teaching according to individual differences means adjusting the pace, method, and content of instruction to each learner's distinct ability, interest, and learning style, rather than delivering the same instruction uniformly to everyone.

To find the exception, check whether each listed practice lets a teacher respond to a particular learner's needs, or instead forces one uniform treatment on many learners at once.

• Individualized instruction shapes the pace and content of teaching around one learner's specific needs, so it is built around differences, not against them.

• Curriculum adaptation reshapes material and delivery to suit different learners' levels, which is again a way of responding to differences.

• Knowledge of a student's abilities is the diagnostic information a teacher needs before any of these adjustments can be made, so it enables attention to differences rather than working against it.

• As conventionally understood in this context, teaching a large group of students means one lesson, pace, and set of content is delivered to the whole class together, rather than being adjusted lesson-by-lesson to any single learner's pace or ability.

The other three practices are each defined by how they respond to a particular learner's ability or pace, while — in that conventional whole-class sense — teaching a large group is defined by delivering one lesson to the entire class at once; this is why it is the practice that does not support teaching according to individual differences.
