Deep Processing

In science education, we often wrestle with the balance between covering content and cultivating deep understanding. We want our students to do more than just recite the periodic table or regurgitate Newton’s laws — we want them to think like scientists, to connect concepts, and to apply their knowledge in meaningful ways.

We want our students to really learn, not just memorize for a test and forget it by the weekend. But what makes some learning experiences stick while others fade? One key lies in how students process information.

Deep processing is complex mental effort that involves manipulating information to achieve depth of understanding. The deeper the processing, the stronger the memory trace and the more likely the knowledge is to be retained and understood.

Compare these two study methods:

• Student A re-reads a textbook chapter three times.

  
  

• Student B reads a passage, explains the key ideas to a classmate, connects them to real-world examples, and creates a concept map.

Even if they spend the same amount of time, Student B is more likely to retain and understand the material because they're engaging in deep processing.

Shallow Processing	Deep Processing
Rote memorization	Explaining concepts in your own words
Highlighting or re-reading without interaction	Making connections between ideas
Focusing on surface features (ex: bold words)	Asking “why” and “how” questions
Observing a phenomenon without discussion	Predicting outcomes and analyzing results
Isolated facts	Integrating new information into existing knowledge

Shallow processing might help students pass a quiz, but deep processing equips them to apply concepts in novel situations and solve problems.

Understanding deep processing helps us design lessons that go beyond surface learning. When we create opportunities for students to engage meaningfully with content through reflection, analysis, application, and synthesis, we promote durable learning.

Let’s explore how this can look in practice.

5 Ways to Design Lessons That Encourage Deep Processing

1.  Build Conceptual Bridges

When introducing new topics, explicitly link them to prior knowledge:

• “We’ve learned about kinetic energy — how does that relate to thermal energy?”

• “Remember diffusion? Let’s see how that plays a role in gas exchange in the lungs.”

These connections make science feel like a coherent story, not isolated facts.

2. Ask Higher-Order Questions

Instead of asking “What is photosynthesis?” try:

• “How would you explain photosynthesis to someone with no science background?”

• “Why is photosynthesis crucial to life on Earth?”

Encourage elaboration by prompting students to go beyond the "what" to explain the "why" and "how". This requires students to interpret, evaluate, and explain — all of which foster deeper thinking and enable students to transfer knowledge to new contexts.

3. Use Retrieval Practice with a Twist

Making connections helps students build a richer mental framework.

Start class with quick retrieval prompts like:

• “Draw and label the carbon cycle from memory.”

• “Without looking at your notes, draw and label a simple diagram illustrating the relationship between photosynthesis and cellular respiration.”

Then, have students compare answers in pairs and identify gaps. 

Retrieval + Discussion = Deeper Learning

4. Use Models and Analogies Strategically

Have students create or critique models:

• “Create a comic strip to represent the hydrological cycle."

• “Explain how biodiversity is like a stock market portfolio.”

Creating representations forces students to translate abstract ideas into something meaningful.

5. Make Room for Metacognition

Reflect on the Thinking Process. Ask students:

• “What part of today’s lab confused you at first, and how did you figure it out?”

• “Which strategy helped you most during this unit?”

Prompting students to think about their thinking (metacognition) improves both engagement and retention. Metacognition helps students become more independent and intentional learners, skills essential for scientific thinking. 

Case studies prompt students to think deeply by placing them in realistic, complex scenarios that require analysis, problem-solving, and decision-making. Here’s how they do it:

1. Real-world context: Case studies simulate real-life situations, which encourages students to apply theoretical knowledge to practical problems. This connection enhances understanding and retention.

   
   

2. Critical thinking: Students must evaluate information, identify relevant issues, and weigh different perspectives. This fosters analytical thinking and the ability to assess complex variables.

   
   

3. Open-ended problems: Unlike problems with a single correct answer, case studies often have multiple possible solutions. This ambiguity pushes students to justify their reasoning and consider consequences.

   
   

4. Discussion and debate: Case studies often involve group discussion, which exposes students to diverse viewpoints and encourages deeper reflection on their own assumptions.

   
   

5. Decision-making under uncertainty: Many cases involve incomplete or evolving information, requiring students to make judgments with limited data—just like in real life.

   
   

6. Integration of knowledge: Solving a case often demands pulling together concepts from various disciplines or areas of study, encouraging a more holistic and connected understanding.

Deep processing isn’t about making lessons harder — it’s about making them more meaningful. By designing instruction that challenges students to think critically, explain thoroughly, and connect ideas, we help them become better learners and thinkers.

In a world that values creativity, problem-solving, and adaptability, that’s a gift that lasts well beyond high school.
