Which statement best describes the three stages of information processing and their classroom relevance?

• A. Sensory memory briefly holds inputs; working memory processes information for current tasks; long-term memory stores durable knowledge via encoding and retrieval.
• B. Long-term memory briefly holds inputs; sensory memory processes information for current tasks; working memory stores durable knowledge via encoding and retrieval.
• C. Working memory briefly holds inputs; sensory memory processes information for current tasks; long-term memory stores durable knowledge via encoding and retrieval.
• D. Sensory memory stores durable knowledge; long-term memory processes inputs; working memory handles automatic tasks.

Answer: (A)

Understanding how information moves through our brain helps explain why certain teaching strategies work. The statement that best fits describes the flow of information as sensory memory briefly holds incoming stimuli, then working memory processes that information for current tasks, and long-term memory stores durable knowledge through encoding and retrieval. In classroom terms, this means we present information in a way that minimizes overload on working memory (e.g., chunking, clear steps, visuals), provide practice and meaningful encoding opportunities to strengthen long-term memory, and use retrieval cues to support accessing that knowledge later. Other descriptions misplace these roles—for example, treating long-term memory as a brief holding area or assigning processing roles to sensory memory or working memory that don’t match how information is actually stored and used. The correct view aligns with how students learn and retain information over time.
