This paper describes the implementation and evaluation of a computer literacy program for 4-year-old Head Start students and their teachers that was developed through the efforts of the Indianapolis Head Start program, the Children's Museum, and the Indiana University School of Education. The report covers: (1) the objectives of the program; (2) a schedule of program activities; (3) staff training prior to the program; (4) plans for the implementation of computer sessions; and (5) criteria for the selection of software. The results of the program are reported, including a comparison of the pretest and posttest scores for the correct identification of computer parts by the children in the experimental group and a control group of nonparticipating children. Observations by the researchers of what they learned from the project are also provided, including observations on staffing, volunteers, parents, and university students who assisted with the project; a listing of skills enhanced during the computer experiences; a summary of general problems and concerns; and observations on teacher training. In conclusion, it is noted that the children found the experience exciting and meaningful, and the project engendered considerable parent involvement. (2 tables and 15 references) (EW)
