In order to help students to become good problem solvers, a teacher should emphasize on the practice of :

The correct answer is: breaking large complex problems into smaller manageable problems.

Explanation:

Problem-solving is a critical cognitive skill in education. To help students become effective problem solvers, educators encourage strategies that simplify and structure complex tasks.

Why breaking down problems works:

• Decomposition (Sub-goal Analysis): Dividing a large, complex problem into smaller, logical sub-problems allows students to tackle each part systematically without getting overwhelmed by the overall complexity.

• Cognitive Load Management: Large tasks require significant mental effort. Breaking them into smaller steps reduces cognitive overload and makes problem-solving more manageable.

• Flexibility & Confidence: Completing smaller steps builds confidence and helps students track their progress clearly.

Why other options are incorrect:

• Focusing on information that confirms existing beliefs (Confirmation Bias): This limits objective thinking and prevents students from considering alternative solutions.

• Approaching problems in a particular fixed fashion (Mental Set/Functional Fixedness): Rigidity hinders creative thinking and adaptability needed for novel problems.

• Centering only on one particular piece of information (Centration): Ignores other critical variables necessary for a comprehensive solution.
