A content analysis of six naturalistic language teaching strategies is reported. The six strategies are enhanced milieu teaching, incidental teaching, responsive parenting, two different types of responsive teaching, and It Takes Two to Talk. Features and characteristics common to all six strategies as well as those that are method-specific are described. Characteristics that stand out as particularly important include interest-based child learning; use of everyday naturally occurring activities as contexts for child-initiated interactions; adult sensitivity and contingent social responsiveness to child initiations; and joint attention plus turn taking as activities for sustaining adult-child interactive exchanges. Other characteristics that have value-added effects are also described. Application of these features to the authors’ research and practice is also discussed.
