The purpose of divergent questions in science classroom can be : (a) to…

In science-teaching pedagogy, questions are grouped as convergent, which expect one fixed correct response, or divergent, which openly admit more than one acceptable response. Because a divergent question never pre-fixes a single 'correct' answer, what a learner writes becomes a window into that learner's own reasoning — divergent questioning therefore works mainly as a diagnostic and thinking-development tool, not as a discussion-facilitation tool.

Reading each candidate purpose against that diagnostic-and-thinking role: divergent questions promote critical thinking, since a learner must reason through and justify one among several plausible responses rather than recall a single fact. Because the same open prompt draws out responses of differing depth, it also lets a teacher discern between students by the sophistication of what each one writes, lets a teacher single out an unusually insightful or gifted response, and surfaces each learner's own alternate or naive conception of the phenomenon being asked about. Developing communication and appreciating subjectivity in science, by contrast, are outcomes tied more specifically to discussion-based classroom techniques — such as debating a socio-scientific issue — than to the divergent-question format by itself. Per the official CBSE/CTET key for this Paper 2 (July 2024) item, the set that stays within divergent questioning's own diagnostic-and-thinking role is: to promote critical thinking, to discern between students, to identify gifted students, and to identify alternate conceptions.

• (a), (b), (c) and (f): swaps in developing communication and appreciating subjectivity in science for the diagnostic purposes of discerning between students and identifying gifted students.

• (a), (c), (e) and (f): keeps identifying alternate conceptions but again brings in developing communication and appreciating subjectivity in science instead of those two diagnostic purposes.

• (b), (d), (e) and (f): keeps three diagnostic purposes but drops promoting critical thinking in favour of appreciating subjectivity in science.

So only the combination of promoting critical thinking, discerning between students, identifying gifted students, and identifying alternate conceptions stays entirely within what a divergent question, on its own, is designed to do.
