This paper analyzes whole language and code-based skills approaches in early literacy and the specific patterns of interaction present in both approaches. Nineteen hours of video data were coded to analyze the nature of whole language versus code-based skills instruction and document the allocation of time spent on each approach in a reading program. Data come from a cross-sectional study in Singapore where the Learning Support Program (LSP), a reading program for low-track students, was studied in five schools. Overall, 73% of class time in the dataset showed code-based skills instruction. However, the approach to instruction changed within the LSP in a linear fashion. Though in the early years of the LSP there was an over-emphasis on code-based skills and lack of variety in patterns of interaction, in later years there was a balance between whole language and code-based skills and a wider variety of interactional patterns.
