Frequency triage

Take twenty unknown words from current reading and rank them by likely recurrence, range and usefulness. Do not use perceived difficulty as the main criterion.

Success standard: The learner can justify the vocabulary choice using frequency, range, academic utility, personal recurrence or disciplinary necessity instead of prestige, length or perceived difficulty.

Transfer: Repeat the prioritisation on a new reading set. Independent learners should eventually make defensible selection decisions without waiting for a teacher to rank every word.

Twelve-week frequency-priority programme

Week 1 audits high-frequency gaps. Week 2 checks depth of common polysemous words. Week 3 introduces high-utility academic vocabulary. Week 4 maps cross-subject range. Week 5 builds collocation return. Week 6 uses word families. Week 7 develops strategies for lower-frequency words. Week 8 uses corpus evidence. Week 9 builds personal-frequency lists from errors. Week 10 shifts selected words into productive use. Week 11 applies priorities under exam load. Week 12 prunes and rebuilds the active vocabulary queue.

Final principle

Frequency is a powerful vocabulary compass, not an automatic curriculum. Secondary 4 students gain the greatest return when they secure the common core, deepen high-utility academic vocabulary, master subject-essential terms and learn efficient strategies for the long tail of lower-frequency words.
