Pre-teach the vocab your class will miss tomorrow

Pre-teach the vocab your class will miss tomorrow

Half your class will read tomorrow's set text and miss about a third of the words. Not the Tier 3 subject vocab you already pre-teach (photosynthesis, alliteration, sedimentary). The Tier 2 words: presume, evident, unremarkable, contend, subsequent. The high-utility words that appear across every subject, that fluent adults do not notice, and that quietly derail comprehension for the students who read least. This is one of the best-evidenced moves in literacy teaching (Beck and McKeown, Quigley, EEF's Improving Literacy in Secondary Schools), and one of the least-done, because auditing a passage for Tier 2 words takes real time. It stops taking real time this morning.

The prompt

You are helping me prepare a five-minute vocabulary pre-teach for a text I am setting my class to read. The goal is to catch the Tier 2 words that will quietly derail comprehension, not the Tier 3 subject-specific words I already teach.

You are working in the tradition of Beck, McKeown and Kucan's "Bringing Words to Life" and Alex Quigley's "Closing the Vocabulary Gap":
- Tier 1: everyday words (dog, house, run). Do not touch these.
- Tier 2: high-utility words that appear across subjects and academic registers (unremarkable, presume, evident, contend, subsequent, arguably, discern). Fluent readers do not notice these. Struggling readers stumble on them. Focus here.
- Tier 3: subject-specific words (photosynthesis, alliteration, sedimentary). I already teach these. Do not list them unless I explicitly ask.

CONTEXT
- Year level: [YEAR LEVEL, e.g. Year 8]
- Subject and unit: [e.g. Year 8 Humanities, causes of WWI]
- What I already taught this class about the topic: [ONE OR TWO LINES]
- The class in one honest line: [e.g. "27 students, reading spread from Year 5 to Year 10 level, 4 EAL/D students who need extra vocab scaffolds"]
- Reading time available in class tomorrow: [e.g. 15 minutes]
- The Tier 3 subject words I have already pre-taught (so you do not list them): [LIST or "none formal"]

THE TEXT
"""
[PASTE the text I am setting. Textbook page, news article, source excerpt, passage from a novel. Include the full text, not a summary.]
"""

PRODUCE, IN THIS EXACT ORDER. NO PRE-AMBLE. START WITH SECTION 1.

1. THE TIER 2 LIST
The eight to twelve Tier 2 words in the passage most likely to trip my class. For each:
- The word.
- The sentence it appears in, copied verbatim from the text, so I can point to it.
- A student-friendly definition in the register a Year [X] student would write. Not a dictionary paste. Use "means" not "denotes".
- A sample sentence in a familiar context, NOT drawn from the passage, so students meet the word once before they meet it in the reading.

Rank the list by trip hazard, most disruptive to comprehension first. Do NOT include Tier 3 subject-specific words.

2. THE FIVE-MINUTE PRE-TEACH
A do-now I can put on the board or read out. Structure:
- Two lines of opener that give students the "why we are doing this" in student words.
- The top four words from the list, each with the student-friendly definition and one prediction question (e.g. "If a sentence starts 'The city presented an unremarkable skyline...', what is the sky most likely to look like?").
- One check-for-understanding question I ask before we start reading, that tells me whether the pre-teach landed.

3. THE READING-LOAD WARNING
Count roughly how many Tier 2 words per 100 words of running text. Tell me the ratio. If it is above 5 per 100, tell me the text is above the accessible threshold for a mixed-ability Year [X] class and give me two options: (a) which sections to cut to reduce the load, or (b) which two additional words to pre-teach and set the class up to read anyway.

4. THE EAL/D NOTE
Two lines. Which words on the list are likely to trip EAL/D students specifically (usually the ones with idiomatic or connotative meaning that a dictionary will not capture: "hardly", "presume", "arguably"). One suggestion for how I front-load these differently.

RULES
- Australian English throughout. Year 8, not 8th grade. Realise not realize. Colour not color. No em-dashes and no en-dashes anywhere. Commas, full stops, and parentheses only.
- Do not open with "here is your vocabulary pre-teach". Start with Section 1.
- Do not list Tier 3 subject-specific words. If a word is obviously technical to the subject, skip it.
- Do not use the word "utilise" in a student-friendly definition. Ever.
- If the passage I gave you is under 200 words, do not pad the list to twelve. Give me the honest number that actually trips comprehension, even if it is three.
- Sample sentences must be plausible for a student's life. "The cafeteria menu was unremarkable" beats "The corpus of Elizabethan sonnets was unremarkable".

What it does well

The two moves that turn this from a word list into a real pre-teach are the ranking by trip hazard and the sample sentence drawn from OUTSIDE the reading. Students meeting a word twice (once in a familiar sentence in isolation, once inside the passage) is the difference between an interruption in reading and a checkable definition retrieval mid-read. The reading-load ratio is the other bit worth having, because it gives you a defensible answer to the "is this text accessible for my class" question that you currently answer on instinct.

Where it falls over

It cannot tell you which students in the room will trip on which words. Your knowledge of your class does that, and no amount of context in the prompt will substitute. The 5-per-100 threshold is indicative, not diagnostic: a dense passage about something the class is invested in will hold their attention past 6 per 100, and a light passage on a topic they are ambivalent about will lose them at 3 per 100.

Also, the model will occasionally slip a Tier 3 word into the list because it looks lexically ambitious. If the word is "photosynthesis" or "alliteration", strike it out. That is your subject vocab. You already teach it.

Try it like this

For Year 7 English on a chapter of a novel: paste the chapter. The list will surface words like "reluctant", "muttered", "vaguely", which change the emotional register but almost never get pre-taught.

For Year 10 Science reading a New Scientist article: paste the article and put the domain words (mitochondrial, oxidative, catalytic) into your Tier 3 list. What comes back will be the connective and modal Tier 2 words (correspondingly, marked, tentatively) that actually make science writing hard to follow.

For VCE English on a set text: paste the SAC prompt AND a short passage of critical analysis together, and ask for the Tier 2 vocab that appears in both. That is the pre-teach for the SAC, not just for the reading.

If you only have five minutes: skip the pre-teach and paste one chunky paragraph. The ranked Tier 2 list alone, read out loud once with a one-line definition each, is more than 90% of your class currently gets.

The teachers who beat the reading-comprehension bell curve over four years are not the ones with the newest phonics scheme. They are the ones who front-load Tier 2 vocab, every text, every week.
