Concept:Conceptual change happens when students modify their existing mental frameworks (schemas) to accommodate new, contradictory information.
A teacher must challenge prior knowledge to restructure understanding.
Explanation:Rote memorization (Option A) does not promote deep understanding, so it is ineffective for conceptual change.
Presenting disconnected chunks (Option C) prevents students from seeing relationships and building new schemas.
Tasks far above a child's cognitive level (Option D) cause frustration and are not manageable.
The best method is to give content that is moderately challenging—just beyond current knowledge—and requires students to revise their schemas (Option B).
This approach builds on prior experience while encouraging critical thinking and integration of new ideas.
It makes learning progressive and analytical, moving from simple to complex concepts.
Teachers should also support discussion and sharing of perspectives to aid schema modification.
Answer:B. present content which is moderately challenging and requires modification of schemas.
