First in a series designed to provide teachers and administrators with a reference tool for identifying, evaluating, and selecting software for use in computer-based teaching and learning, this guide describes those resources available through the New York State Education Department and regional services throughout New York. The activities and services of the Center for Learning Technologies (CLT) are highlighted, followed by a description of Demonstration and Technical Assistance Centers and of the CLT's efforts to improve the quality of commercially available hardware. A report on activities conducted to plan and test a statewide telecommunications network emphasizes how the proposed network would facilitate the exchange of information in educational software and technology applications. Two other support resources are discussed, the Media Distribution Network and Computer Training Labs, which provide materials and professional development resources designed to help practitioners bring technology into the classroom. A general purpose glossary and a 38-item bibliography are included. Appendices provide a list of software publishers participating in CLT software initiatives and software publishers who attended a 1982 New York State Department of Education conference. (LMM)
