An instrument used to assess educational environments for computers as new tools for teaching and learning was studied in grades 2, 3, and 4 of the Atlanta (Georgia) Public Schools (APS) in May 1990. The instrument contained 46 items indexing: (1) the immediate and expanded spaces for the computer stations; (2) the presence of software and manuals; (3) teacher practices; and (4) student perspectives. Items were constructed from a list of teacher proficiencies claimed as outcomes resulting from contracted teacher training provided by the software vendor. Data were collected by observers in randomly selected classrooms representing all elementary schools in the APS. Observations were attempted in 338 classrooms. Univariate statistics and norming analyses are presented for all items and selected transformations. Reliabilities and coefficients for the full scale and selected subscales are tabulated and discussed to give a picture of computer use in these elementary schools. The desired teacher proficiencies were not revealed by this study. Eighteen tables present study data. Appendix A presents the Observation Schedule for Computers in the Classroom Environment; and Appendix B is a 326-item list of observer comments. A 33-item list of references is included. (SLD)
