Spaced vocabulary review: a practical routine between language lessons

A learner uses an expression during a lesson, answers the exercise correctly and then cannot recall it in conversation the following week. Before adding another word list, look at what happened between those lessons: was there an opportunity to try to remember and use the expression again?

Spaced vocabulary review means revisiting words and expressions at separate points over time. When learners try to remember before checking the answer, the activity also involves retrieval practice. The aim is not simply to recognise a familiar list, but to access language when it is needed.

For independent teachers and small language schools, the approach must fit the working week. This guide offers a planning model, not a universal memory formula: a small set of useful expressions, brief tasks, answer checking and reuse in different situations.

What the sources recommend, and what we are proposing

The Australian Education Research Organisation’s (AERO) Vary practice guide recommends spacing practice opportunities, varying tasks and teaching learners how to revise. It also warns against repeating errors without feedback. This is a research-informed guide for primary and secondary education, not a trial of this particular routine with adult language-school learners.

On the British Council’s TeachingEnglish website, Richard Frost recommends recycling vocabulary, using personalised examples and teaching learners to test their memory at regular intervals. Leo Selivan discusses the limits of counting encounters: the quality of language use and the feasibility of review within a school timetable matter too.

The routine below is our operational suggestion based on these principles. The numbers of items, minutes and days are adjustable starting points, not scientifically guaranteed settings.

1. Choose expressions learners have a reason to use

Start with five to eight items from a lesson or short teaching sequence. Choose expressions linked to a communicative goal rather than a random selection of words.

For an English lesson about arranging to meet, for example:

• Are you free on …?
• Does … work for you?
• Could we move it to …?
• Something came up.
• Let’s confirm …

Teach meaning, form, pronunciation and use in context. Explain, for instance, that Something came up signals an unexpected event and may need to be followed by a request to reschedule. Review does not replace this initial work on understanding.

Keep a simple record for each item: expression, example, prompt and model answer. The prompt should invite an attempt without revealing the answer. “You need to reschedule a meeting: how do you suggest another time?” serves this goal better than displaying the entire expression and asking whether the learner recognises it.

2. Pair retrieval attempts with answer checking

Demonstrate the process during the lesson before expecting learners to do it independently:

1. Read or listen to the situation without opening the answer.
2. Try to respond from memory, orally or in writing.
3. Check the model and notice one relevant difference.
4. If necessary, use a small hint and try again.
5. Reuse the expression in another example.

Do not turn every attempt into a test. If learners cannot recall an item, offer support: a picture, the first word or a short model. If the meaning is still unclear, return to explanation rather than asking them to keep guessing.

Distinguish recognition from production, too. Selecting the correct option can provide initial support; making a request without options offers different evidence. Neither task alone establishes general mastery of an expression.

3. Use a workable schedule between lessons

For weekly lessons, try the following routine. The timings suggest a manageable workload; they are not requirements:

• At the end of the lesson: allow two or three minutes to recall expressions without looking at the material, then check the models.
• The next day: set a three-to-five-minute activity with short situations and model answers available after the attempt.
• Midweek: ask for a brief message or audio recording using some expressions in a different situation.
• At the start of the next lesson: invite another attempt without the list visible and use difficulties to decide what to revisit.
• In a later lesson: mix some of these items with more recent language so they do not disappear when the unit ends.

If the group meets twice a week, distribute review opportunities between those lessons. If a learner can only study once outside class, start there. An unrealistic timetable does not become more useful because its intervals look precise.

Instructions for learners: “Try answering before opening the model. If you cannot remember, use the hint, check and try again. Mark only what you would like to revisit with me.”

4. Change the situation while keeping the focus

Repeating the same dialogue every time can make the task too familiar. Keep the target expressions, but change the reason for using them.

First review: “You want to meet a friend on Friday. Ask if they are free.” One possible model: Are you free on Friday?

Second review: “You have a meeting tomorrow, but something came up. Suggest Thursday instead.” One possible model: Something came up. Could we move it to Thursday?

Third review: in pairs, one learner has two available time slots and the other needs to negotiate an alternative and confirm the arrangement.

These are different tasks within one sequence, not three scripts to memorise. Accept natural alternatives that achieve the goal. If a task requires a particular expression, make that explicit; a communicatively appropriate answer should not become “wrong” simply because it differs from the model.

For beginners, simplify the scenario and provide prompts. For more advanced learners, add register choices, explanations or follow-up questions. The challenge should come from using the language, not from confusing instructions.

5. Record enough to make decisions without marking everything

A minimal record can include the item, attempt date, task type, support needed and next action. Use descriptive categories:

• Still needs a model: revisit meaning or form and provide guided practice.
• Recalls with a prompt: try again with less support.
• Uses without a prompt in this task: return to the item later in another context.

The last category does not mean “learned forever”. It describes a particular observation. To monitor progress, compare similar tasks separated in time and record any help provided; do not treat a multiple-choice question and a free conversation as equivalent measures.

When giving feedback, prioritise what affects the goal: for example, making a clear request or using the expression’s preposition. Provide models for self-checking and reserve individual feedback for questions or recurring patterns. You do not need to listen to a long recording from every learner at every review point.

Making the routine work in a small school

Standardise the process, not every answer. The team can share a template containing the week’s objective, target expressions, prompts, possible answers and review opportunities. Each teacher adapts the examples to their learners.

Keep instructions, materials and exercises in the learning environment the school already uses. If you use Slingui, connect this routine to your lesson and exercise organisation without assuming an automatic spaced-repetition scheduler. The pedagogical design and decisions about when to revisit items remain the teacher’s responsibility.

Before extending the routine to every group, try one sequence and check three things: did learners understand how to practise without looking at the answer? Could they fit the task into their week? Did the next lesson’s attempt provide useful planning information? Adjust the workload before adding more items.

Frequently asked questions

Is there an ideal interval for every learner?

Do not treat a single schedule as a guarantee. Use available lesson times and observed performance to adjust review opportunities. Persistent difficulty may require more explanation or support, not just a shorter interval.

Do I need an app or flashcards?

No. Cards, a document with separate answers or activities in a digital learning environment can all work. The essential elements are an opportunity to try to remember, check and reuse. Cards are a tool, not the final goal.

Does this guarantee student retention at the school?

No. Remembering vocabulary and staying enrolled are different outcomes. Monitor learning through learners’ ability to retrieve and use language; treat satisfaction, attendance and renewals as separate indicators rather than promising that one study technique will solve student dropout.

Start with the next lesson

Choose one communicative goal and a small set of expressions. Prepare a guided attempt, a short review between lessons and a fresh situation for the following lesson. Only then decide whether to increase frequency or volume.

Review becomes more useful than “study the words at home” when learners know what to attempt, when to check and how to use the language again.
