Begin with the physical situation
Before choosing a formula, identify the objects, interactions, known quantities and the result being sought.
Connect words, diagrams and equations
A diagram should express the same relationships as the written statement and the mathematical model.
Practise in increasing difficulty
Direct questions establish the method; mixed questions teach students to select the right principle independently.
Review errors
Classify an error as conceptual, mathematical, interpretive or due to incomplete practice, then address the cause.
