A plan for evaluating the Apple Classroom of Tomorrow (ACOT) is presented, which implements the model for Sensible Technology Assessment/Research (STAR). STAR involves interactive participation in the evaluation study by ACOT participants, collateral university researchers, and University of California (Los Angeles) staff to develop a credible, adaptive set of assessment plans, procedures, and reports assessing the ACOT experiment; a phased implementation of STAR designed to conform to the rhythms of site-by-site implementation; and a focus on exploring the utility of developing STAR into a multi-user evaluation system for future coordinated implementation with new technology adoption in local districts. The STAR evaluation will be guided by questions concerning: (1) the effects of ACOT on students; (2) the influence of ACOT on organization and delivery of instruction; (3) the effects of ACOT on teachers; (4) the effects of ACOT on students' families; and (5) unintended effects that may be attributed to ACOT. The comparative impact of ACOT will be investigated for three groups of students: ACOT students over time; students at one grade level taught by an increasingly experienced ACOT teacher; and ACOT and non-ACOT students in the same and different schools. Investigation of the effects of ACOT on students will consider academic achievement, criterion-referenced student writing, problem solving, locus of control or sense of efficacy, attitudes toward school or motivation for schooling, academic self-concept, future educational and career plans, use of time at home, and site-specific and instructional goals. Similar issues will be considered for teachers and families. The evaluation was scheduled to begin in Spring 1988 at three selected ACOT sites in Memphis (Tennessee), Nashville (Tennessee), and Columbus (Ohio). (SLD)
