A Non-Enabling Framework for Productive Collocation-Based Vocabulary Item Design (v1.0)

Abstract
This report outlines a theory-only approach to designing vocabulary items that assess productive
collocation rather than rote recall. The approach draws on three strands: Ellis s focus on form and
form function mapping in natural discourse; Nation s account of depth of vocabulary knowledge
(sense, collocation, constraints); and Krashen s notion of comprehensible input (i+1) in context. T
avoid enabling replication, the report withholds algorithms, parameters, thresholds, corpus
identities, prompt specifications, and code.
