The Milwaukee Project is an attempt to provide science teachers at all grade levels with the background and support they need to involve handicapped students in a regular science class. Goals of the project include the improvement of preservice and inservice teacher training to prepare teachers to include the handicapped child in the mainstream and the preparation, modification, and dissemination of material resources which will help insure success for the individuals involved. To aid in the attainment of these goals, demonstration and inservice centers have been established at the elementary, middle, and high school levels where classroom teachers learn through observation and direct involvement to work with mainstreamed, handicapped students in regular classroom settings. The centers are regular classrooms following the regular curriculum. No special or unique equipment has been placed in these classrooms so that visiting teachers will see that, in most cases, materials need only be modified to achieve success. Teachers attending these centers work with handicapped students, performing the laboratory activity scheduled for that day. Operation of the centers, modification of class materials, and teacher reaction are discussed. (Author/JN)
