How to Learn Engineering Concepts Instead of Memorising?

1. The Feynman technique: simplify and explain

Named after physicist Richard Feynman, this technique involves teaching a concept in simple language as if explaining it to someone with no prior knowledge. If you struggle to explain a concept clearly, it’s a sign that you don’t fully understand it yet. This method pushes students to identify gaps in their knowledge and build a deeper understanding of complex concepts.

• Choose a topic: Select a concept you’re studying and try explaining it in simple language, as if teaching someone who has never heard of it.
• Identify gaps: If you struggle to explain certain parts, go back to the source material to fill in those gaps.
• Simplify your explanation: Use analogies or simple language that breaks down complex ideas.
• Review and refine: As you get better at explaining, refine your explanations and repeat the process to solidify your understanding.

2. Chunking information for better recall

Instead of learning concepts as isolated pieces of information, break them down into smaller, interconnected chunks. In engineering, breaking down large, complex topics, such as fluid mechanics or thermodynamics, into smaller, manageable parts can make them easier to digest.

• Divide complex concepts: Break down large topics into smaller, manageable subtopics or steps.
• Group-related information: Identify connections between different ideas and group them to improve recall.
• Use headings and subheadings: When studying, create clear headings for each chunk of information to keep everything organised.
• Review chunks regularly: Regularly revisit each chunk of information to reinforce memory and understanding.

3. Use visual aids and concept maps

Visual aids, such as diagrams, flowcharts, and concept maps, are essential for mastering engineering concepts. These tools help students see the relationships between different ideas, which makes complex concepts more accessible. Concept maps are especially useful in engineering, where topics are often interconnected. For example:

• In electrical engineering, creating a flowchart to understand the relationship between voltage, current, and resistance can help make Ohm’s law clearer.
• In structural engineering, diagrams illustrating load distribution can enhance understanding of force analysis.

4. Spaced repetition: reinforce learning over time

One of the best techniques for long-term retention is spaced repetition. This involves reviewing material at increasing intervals. By revisiting concepts after a few hours, then days, and eventually weeks, students reinforce their understanding.

• Start with short intervals: Review the material within a few hours after learning it to strengthen initial memory.
• Gradually increase review time: Extend the intervals between each review session (e.g., after 1 day, 3 days, 1 week).
• Focus on difficult topics: Spend more time reviewing concepts you find challenging, as they will need more reinforcement.
• Track your progress: Regularly monitor which concepts need more attention based on how well you remember them.
