Concept:Computational skills in mathematics are best developed when students first understand the underlying concepts and procedures, and then reinforce them through regular practice. This combination builds both reasoning and fluency.
Explanation:The question asks which approach most effectively enhances computational skills. Let’s evaluate each option:
-
Option A (describing algorithms only): This provides only theoretical steps without application, so students may memorise procedures but lack the ability to apply them accurately.
-
Option B (conducting hands-on activities): While engaging, activities alone do not ensure the repetitive drill needed to achieve speed and error-free computation.
-
Option C (giving conceptual knowledge): Conceptual understanding is essential, but without procedural clarity and practice, students may not develop the automaticity required for computations.
-
Option D (clarifying concepts and procedures followed by a lot of practice): This combines clear understanding of why and how to compute with sufficient repetition, leading to both accuracy and speed. This is the most effective method.
Thus, the correct choice is the one that integrates explanation with consistent practice.
Answer:Option D – clarifying concepts and procedures followed by a lot of practice.
