This report, the first in a series of six, was developed during Phase II of California's Educational Technology Programs. School-based educational technology projects that were assessed for the study were funded in 1989-90 and implemented in 1990-91. The results from the following staff-developed assessment instruments and evaluation procedures are presented in this report: (1) School-Based Grant Self-Assessment Inventory; (2) student surveys; (3) teacher surveys; (4) interview inventories; (5) case studies; (6) School Profile Page of each project applications; (7) California Technology Project (CTP) Self-Assessment Inventory; (8) Instructional Television (ITV) Self-Assessment Inventory; and (9) Level II and Level I Model Technology School Project Self-Assessment Inventories. A three-tiered plan was used for data collection as follows: Tier One--survey assessment of all schools funded during Phase I (285 sites returned completed surveys); Tier Two--in-depth assessment of a representative sample of 30 school-based projects; and Tier Three--case studies of 11 selected projects. A Profile of the First Phase of School-Based Technology Grant Projects is appended together with copies of the evaluation instruments used. Findings from the Self-Assessment Inventories, telephone interviews, teacher and student surveys, and visitations to 12 school sites are summarized according to planning; content; implementation and staff development; support resources; funding support; supporting and implementing factors; cost benefits; and outcomes. Recommendations for planning, funding, staff development, evaluation, and dissemination are also included. (AEF)
