Learners having trouble with the literacy or numeracy of a task may: ask for help often never ask for help to avoid drawing attention to themselves avoid doing the task use coping strategies for getting around the task display inappropriate behaviours to divert attention from the task. How should you approach learners with LLN needs? The following qualities should inform your dealings with these learners: Tact – the learner is in a vulnerable position. Respect – they have risked returning to a formal educational setting. Confidentiality – a private chat is a much better strategy than pointing out the learner’s difficulties to them in front of other learners. Supportiveness –you are in a position to encourage a learner who may previously have experienced failure and criticism in educational settings. Openness - Full explanation of any formal strategies (such as extra classes or an alternative pathway) is important to ensure the learner fully understands their own needs and the reasons for any advice you may give them. Some training strategies for learners with LLN needs Be aware of the LLN needs of your learners and adapt your training strategies to maximise their chances of learning.
