You Can’t Learn What You Can’t Connect

Why does activating prior knowledge and using analogies strengthen durable learning

Overview for Educators

One of the most consistent findings in cognitive science is that learning does not occur simply because information is presented clearly. Rather, meaningful learning occurs when new ideas connect to prior knowledge already stored in long-term memory. In You Can’t Learn What You Can’t Connect, the author draws on the work of cognitive scientist Héctor Ruiz Martín to explain why connections between existing knowledge and new content are essential for retention, transfer, and understanding.

Educators often observe students who appear to understand a concept during a lesson but struggle to apply it later. This phenomenon reflects what researchers call inert knowledge—information that can be recalled temporarily but has not been integrated into a student’s broader cognitive framework. Without meaningful connections to existing schema, new information may be quickly forgotten or remain difficult to apply in new contexts.

The article highlights the powerful role of analogies as instructional tools that help students connect unfamiliar ideas to familiar experiences. By anchoring abstract concepts to existing knowledge, educators increase the likelihood that learning will become durable and transferable.

The Role of Prior Knowledge in Learning

Learning is not simply the accumulation of isolated facts. Instead, the brain organizes information into interconnected networks of meaning. When students encounter new material, they attempt to connect it to what they already know. If no connection exists, the information is more likely to remain abstract and difficult to retrieve later.

Prior knowledge serves as a cognitive anchor that helps students interpret and organize new ideas. Instruction that activates existing schema makes learning more efficient and more meaningful.

Research consistently demonstrates that students learn more effectively when teachers:

• activate relevant prior knowledge before introducing new content • provide context that links new ideas to familiar experiences
• use examples that align with students’ existing understanding
• create opportunities for students to explain ideas in their own words

Without these connections, even well-structured explanations may fail to produce lasting understanding.

The Power of Analogies

Analogies provide a practical method for connecting new knowledge to familiar concepts. By highlighting similarities between known and unknown ideas, analogies help students build mental bridges that support comprehension.

The article provides several classroom examples illustrating how analogies can clarify complex concepts:

• comparing evaporation and drought conditions to grapes turning into raisins helps students visualize how heat removes moisture

• describing snowpack as a savings account helps students understand how stored resources are used over time

• comparing fire suppression to avoiding practice or homework helps students recognize how avoiding small challenges can lead to larger problems later

In each case, the analogy does more than simplify the concept—it connects new information to existing knowledge structures, making learning more meaningful.

Moving Beyond Surface-Level Learning

Students may demonstrate short-term understanding without achieving deep learning. When students can repeat information but cannot apply it flexibly, the learning remains fragile.

Meaningful learning requires integration into long-term memory networks. Instruction that emphasizes connections helps students transfer knowledge across contexts and apply concepts in novel situations.

Educators can strengthen meaningful learning by:

• asking students to relate new concepts to personal experience • encouraging explanation rather than memorization
• using multiple examples that reinforce conceptual relationships
• revisiting key ideas across time
• promoting discussion that builds connections across topics

Learning becomes durable when ideas are connected rather than isolated.

Implications for School Leaders

School leaders can support instructional practices that prioritize meaningful learning by encouraging professional development focused on cognitive science principles.

Leaders can promote:

• instructional strategies that activate prior knowledge • collaborative lesson design that emphasizes conceptual connections
• use of analogies to support comprehension of abstract concepts
• classroom discussion practices that deepen understanding
• curriculum alignment that reinforces key concepts across grade levels

Supporting instructional approaches grounded in cognitive science can improve student retention and transfer of learning.

Conclusion

Clear explanations alone do not guarantee lasting learning. Students retain knowledge when new information connects to existing schema in meaningful ways.

Analogies provide powerful tools for building these connections, helping students transform abstract concepts into usable knowledge.

If learning is to be durable, instruction must begin with what students already know and intentionally build bridges to new understanding.

Learning sticks when ideas have somewhere to go.
