Spiral Syllabus

A curriculum design in which key concepts and skills are revisited repeatedly at increasing levels of complexity. Originated with Jerome Bruner (1960, The Process of Education).

Core Principle

"Any subject can be taught effectively in some intellectually honest form to any child at any stage of development." — Bruner (1960)

Items are not taught once and dropped; they recur through the course with deeper treatment, wider application, and greater learner autonomy each time.

Why It Suits Language Learning

• Language acquisition requires multiple exposures across varied contexts — one encounter rarely leads to mastery
• Aligns with spaced repetition and retrieval practice research
• Mirrors natural acquisition: learners revisit the same structures at progressively higher levels of control (from recognition → controlled use → free production)
• Prevents the "coverage illusion" of linear syllabi where items are ticked off but not acquired

Design Features

• Explicit recycling built into the syllabus map
• Each revisit adds complexity (new contexts, combined structures, less scaffolding)
• Assessment tasks at each cycle measure deepening competence

Practical Implications

• Particularly effective for grammar and vocabulary syllabi
• Requires deliberate planning — recycling must be systematic, not incidental
• Complements TBLT where task complexity increases across cycles
• The EH IELTS program uses spiral design: the same skill types recur from IF1 to IM at increasing band-level demands
