Tabular data, computer printouts, survey forms, and field notes are included in these appendices to an independent evaluation of the Basic Skills Learning Centers (BSLC) Projects implemented by Southwest Educational Development Laboratory (SEDL) and Southwest Regional Laboratory (SWRL). The wide range of supporting data focus on project implementation and pupil achievement in the two programs, each designed to improve basic reading and mathematics instruction in nonurban elementary schools, but with different target populations (i.e., SEDL-BSLC was developed for monolingual English-speaking students; SWRL-BSLC included Spanish-speaking students and provided for bilingual instruction). Survey results are summarized separately for SEDL and SWRL projects; specific items include teacher education and language background, student ethnic and language characteristics, time spent in BSLC instruction, and teacher rating of BSLC materials. Field notes summarize project evaluators' visits to inservice teacher training sessions, formal and informal meetings with project coordinators, and classroom observations. Tables and computer printouts provide reliability analyses for various measures of student progress. A narrative history of the evaluation recounts the process by which program sponsors, developers, and the independent evaluators reached a consensus on evaluation goals and format. (JH)
