This report provides baseline information from the six schools in Arkansas, Louisiana, New Mexico, Oklahoma, rural Texas, and urban Texas participating in the Applying Technology to Restructuring and Learning (ATRL) project, which seeks to create replicable models of constructivist learning environments supported by technology. The information in this report was collected in the spring and fall of 1998 from teacher surveys; state, district, and school reports; classroom observations; and field notes from initial on-site visits. The purposes of these data are to enable the project team to compare initial classroom conditions with the development of constructivist learning environments supported by technology and to examine how these environments change instructional practices and student learning. Findings for each site are organized under the following headings: The Community and Environs; State Support for Technology; District Overview; Description of School Site; Project Participants; Teacher Self-assessment in Technology; and Observations of Classroom Practices. Appendices include letters of understanding/intent, the technology skills self-assessment checklist, and the classroom observation form. (AEF)
