Information Bottlenecks

Curriculum design and implementation form a multi‑level system shaped at every step by information bottlenecks. Scientific knowledge must be compressed into teachable representations; curriculum developers must select and structure only a fraction of what is known; teachers must further filter and adapt these materials for their context; and learners themselves must compress rich experiences into the minimal forms that assessment can detect—if not into durable knowledge for life.

Understanding how these constraints shape communication helps us see curriculum not as a pipeline, but as a series of adaptive compression problems. Each actor—researcher, designer, teacher, student—faces limits on time, attention, and representational capacity. Information bottleneck models offer a principled way to analyze these constraints and to design curricula that preserve what matters most while reducing unnecessary load.
