Affective filter

the affective filter may interfere with language acquisition because it involves public practice and speaking in front of others.  The risk involved in public practice can produce anxiety that blocks the learner’s ability to process new information.  To counteract the affective filter, teachers can create an effective learning environment for ELLs that helps them integrate into their new school environment (e.g., provide a nonthreatening classroom experience and demonstrate to ELLs that their needs are understood.)
