This annotated bibliography on developmental learners at the postsecondary level was compiled and edited from computer searches of relevant databases as well as a manual library search. Annotations are organized according to specific types of developmental learners and specific types of developmental education programs and services. Annotations were selected on the basis of research methodology and implications for collegiate educators and date from 1966 through 1992. The 80 items are grouped into the following categories: research identifying developmental learners (definition, historical overview, characteristics); research identifying the needs of developmental learners (programs and services); research identifying developmental education; research identifying differential perspectives; research identifying the curriculum of developmental education; research regarding retention of developmental learners; research identifying the diversity of developmental learners; and research identifying the effectiveness of mathematical programs on developmental learners.
