An innovative instructional intervention model is presented that represents a promising approach to the education of language minority students. One of the four handbooks produced to document and disseminate the findings of the Innovative Approaches Research Project (IARP), this handbook describes the IARP model for providing science and mathematics instruction. School personnel, parents, and educational planners can use it to assess the appropriateness of the intervention for their schools, and teachers can use it for explicit advice on implementing the model. The Cheche Konnen ("search for knowledge" in Haitian Creole) model uses a collaborative inquiry approach to science in which students pose their own questions, plan and implement research, collect and analyze data, build and revise theories, draw conclusions, and make decisions. The goal is for students to develop scientific ways of thinking, talking, and acting. The Cheche Konnen approach is interdisciplinary in its use of literacy skills and the use of mathematics and computers as tools for explaining and communicating scientific findings. The model was tested with Creole-speaking Haitian students in two urban eastern schools, a public elementary school and a public high school. This handbook describes the implementation of the model and examples of the scientific inquiry method that were conducted and assessed in the field test with seventh and eighth grade students. Illustrations, student work samples, margin notes, which summarize the contents of each page, lists of contacts and materials available, and a bibliography are included. (LB)
