    Experts use deep problem structures for similarity judgments, while novices can learn to use principles for better problem-solving. Understanding these strategies enhances learning.

    Area of Science:

    • Cognitive Psychology
    • Physics Education

    Background:

    • Problem-solving ability is crucial in classical mechanics.
    • Understanding how individuals judge problem similarity informs teaching strategies.

    Purpose of the Study:

    • To investigate the relationship between problem-solving skills and the criteria used for judging problem similarity.
    • To compare expert and novice approaches to problem similarity.

    Main Methods:

    • A similarity judgment task comparing experts and novices.
    • Analysis of reasoning strategies employed by novices with varying levels of principle-based judgment.

    Main Results:

    • Experts prioritize deep structural features over surface features for similarity.
    • Novices primarily use surface features but can utilize deep structures.

  • Novices using principles show expert-like categorization and higher problem-solving scores.
  • Conclusions:

    • Principles are fundamental to conceptual and procedural knowledge in effective problem solvers.
    • Developing principle-based reasoning enhances problem-solving ability across all levels.
