Instructional means to lower the filter

Krashen's suggestion:

TPR: "...students are not asked to to produce in the second language until they themselves decide they are ready" (p.141).

Group work as best kind of interaction.

Schinke-Llano and Vicars (1993) study: group work ranked as least anxiety provoking.

Instructor's affective variables:

"If teachers show poor affective variables in class, it may lead yo students fully loosing interest of the subject and even have a negative feeling about language learning" (Li, 2012, p.72).
