By January of the 1991-92 school year, 428 children were being served by the Chapter 1 Prekindergarten Program of the Saginaw, Michigan school district. A process evaluation was conducted to monitor the program and assess whether the program was being implemented as planned. The process evaluation for this year consisted of a half-day classroom observation in 13 classrooms. An activity checklist and observation instrument were used to determine whether cognitive, psychomotor, parent participation, and education activities were being carried out and to explore classroom practices and teacher behaviors for encouraging pupils' language behavior. Observations revealed that: (1) activities to meet the program's daily objectives took place in all classrooms; (2) a record of parent participation was maintained in all classrooms; (3) labels were placed on objects throughout the classrooms to assist in word recognition; and (4) teachers used language enhancement techniques. Overall, the program was operating as planned. Suggestions for improving some areas of the program are offered. Appendixes include a list of program participants, copies of the activity checklist and observation instrument, and a table listing teachers' use of language enhancement techniques. (BC)
