Pre-teaching vocabulary: the decision rule
Deciding which words to pre-teach is one of the most important judgments a teacher makes. Pre-teach too much, and you remove the challenge. Pre-teach too little, and learners struggle. The decision rule is simple: pre-teach only blocking words that cannot be inferred.
The idea
Not all unknown vocabulary needs explicit instruction. Some words can be guessed from context, especially when the surrounding text provides clear clues. Other words are central to understanding and cannot be reasonably inferred. The decision rule asks teachers to evaluate each potential unknown word against two criteria: does it block meaning, and can it be inferred? If the answer to both is yes, pre-teach it. If the answer to either is no, leave it for contextual guessing or ignore it. This rule prevents over-preparation and respects learners' inferential abilities.
An example
For a B2 reading text about economic policy, "austerity" is a blocker. It is central to the argument and unlikely to be guessed from context. "Budget" is not a blocker. Learners can infer its meaning from surrounding words like "spending," "cut," and "government." I once spent twenty minutes pre-teaching fifteen words, only to discover that ten were unnecessary. The learners understood the text without them. Selective pre-teaching is more efficient and preserves the challenge of encountering unknown words.
Before your next reading lesson, identify every potential unknown word. Apply the test: blocker plus uninferrable? Pre-teach. Everything else? Let it go. You will save time and keep learners engaged with the text.Article 0027 sanitized text
Gist first, then detail
A well-sequenced listening or reading lesson moves from easy to hard. Start with gist, then move to specific information or detail. Each stage builds on the previous one, protecting learner confidence.
The idea
When learners attempt detail tasks on a first listen or read, they often become anxious and miss the bigger picture. Gist tasks are easier because they require only general comprehension. Success at this stage builds confidence and provides context for the detail work that follows. The sequence is deliberate: gist first, then specific information, then detail. This order mirrors how we naturally process language. We first understand what something is about, then we look for specific points, and finally we attend to nuances and exact meanings.
An example
I played a recording of a café conversation for an intermediate class. First, I asked: "Where are they, and what are they doing?" Most students answered correctly: "In a café, ordering food." This was the gist. Then I asked: "What three things do they order?" This required a second listen, because the orders were mentioned in passing. Finally, I asked: "What does the woman say about the price?" This was detail work, requiring careful attention to a specific exchange. Each stage prepared them for the next. Without the gist, the detail would have felt random and overwhelming.
Try this
Take one audio and split it into two tasks. Gist for the first play: "What is the main topic?" Detail for the second play: "Find three specific pieces of information." Never ask for detail on a first listen. The sequence matters.
