The Southwest Regional Laboratory (SWRL) Mod 2 Reading Program is planned as a four-year program (K-3) for teaching reading skills to primary-grade children. The materials from the first- and second-year reading programs are designed with the following two goals in mind: to identify sentence structures that are beyond the syntactic capacity of the child at a given level, and to indicate areas where more complex sentence structures could be used. Implications for further development are also presented. (Author/RB)
