Use tiers as a planning tool
A common teaching framework groups words into three broad tiers. Tier 1 includes everyday words that may already be familiar. Tier 2 includes broadly useful words found across different texts. Tier 3 includes terms closely tied to a particular subject.
These categories are a guide, not a universal ranking or a fixed test of difficulty. A word familiar to one learner may be new to another. Language background, reading experience, and the current topic all affect what needs teaching.
Look for words that travel across subjects
Words such as contrast, significant, and approach can appear in many settings. Contrast might describe two characters, two arguments, or two results. That range can make a word a useful choice for explicit discussion.
Choose words from the actual text or task learners will meet. Ask whether the word matters to understanding and whether it offers useful opportunities to discuss meaning. Do not choose it only because it appears on a tier list.
- Does it help explain an important idea?
- Will learners encounter it elsewhere?
- Does its meaning shift with context?
Teach an example and a boundary
Start with a plain explanation, then show a concrete example. If you teach significant as important in a particular context, ask why one detail changes the interpretation of a story while another detail does not.
Show a non-example or a near miss as well. Invite learners to explain their choice. If the word has a specialist meaning, such as a use within statistics, identify that separately instead of assuming the general definition covers every setting.
Check transfer into a new task
After practice with the original passage, use the word in another subject or situation. Ask learners to explain it, interpret it in a sentence, and use it where appropriate. These checks reveal different aspects of understanding.
Revise the list as you learn more about the group. Some words need more examples; others are already secure. A short, purposeful collection with time for discussion is more useful than a label attached to every unfamiliar word.
