Which set of learner characteristics may be considered helpful in designing…

Concept: In designing an effective teaching-learning system, only those learner characteristics that influence how a learner engages with, processes, and needs support with subject content count as useful inputs — for instance, a learner's grounding in the subject, their subject-specific ability, their language background, and their motivational orientation. Personal or social attributes unconnected to subject-learning, such as relationships outside the classroom or compliance with a dress code, do not inform instructional design.

Application: Checking each characteristic against this principle:

1. Prior experience of learners in respect of the subject — bears directly on how content should be sequenced and paced, so it is relevant.

2. Learners' interpersonal relationships with their family friends — a social factor outside the subject-learning domain, so it does not inform instructional design.

3. Ability of the learners in respect of the subject — determines the difficulty level and scaffolding a learner needs, so it is relevant.

4. Student's language background — affects the medium and vocabulary used in instruction, so it is relevant.

5. Interest of students in following the prescribed dress code — a discipline/compliance matter unconnected to how content is taught or learned, so it is not relevant.

6. Motivational orientation of the students — shapes the engagement strategies a teaching-learning system must build in, so it is relevant.

Cross-check: Every offered combination containing item (ii) or item (v) pulls in a non-academic, non-instructional factor, while every combination omitting any of items (i), (iii), (iv), or (vi) drops a genuinely relevant characteristic. Only one combination contains exactly the four relevant characteristics and excludes both non-academic ones.

Result: The set of learner characteristics helpful in designing an effective teaching-learning system is (i), (iii), (iv) and (vi).
