Managing the Learning Environment
Interaction is the main resource
In CLIL the classroom is a language-rich environment where learners must both understand and use the target language. Managing this means planning interaction patterns: teacher–whole class for input and modelling, pair work for rehearsal before public speaking, small-group work for collaborative tasks, and individual work for consolidation. Group work only produces language if learners have group roles (recorder, reporter, timekeeper), a clear outcome, and the functional language they need to negotiate - otherwise they revert to L1 or to silence.
Teacher talk should be comprehensible: slower pace with natural intonation, clear signposting, repetition and paraphrase, key points written as well as spoken, and visuals accompanying explanations. Instructions are best given in short, sequenced steps with a demonstration and a comprehension check ('look at the model - which part is the conclusion?') rather than 'Do you understand?'.
A low affective filter matters: learners are taking risks in a foreign language while tackling demanding content, so errors are treated as a natural stage of learning. Correction is selective - accuracy on the target structure for the lesson, tolerance of errors that do not block meaning, and recasting rather than stopping the flow. Feedback should be about content as well as form.
Routines and displays carry language load: word walls, process diagrams, functional phrase posters, bilingual glossaries and clearly labelled resource areas. Seating should allow pair and group work and eye contact; resources should be accessible without teacher mediation.
Traps: believing L1 use in group work is always a failure; confusing 'noisy' with 'off-task'; options that treat group work as a reward rather than a designed language opportunity; assuming comprehension checks are yes/no questions.
Rule of thumb: never give a collaborative task without also giving the phrases to do it ('I think…, because…; What do you think?; Can you repeat that?').
