This study was designed to arrive at a possible consensus of expert opinions as related to teacher use of library media centers in American public education, and to analyze the essential teacher skills and knowledge suggested by the experts through this systematic methodology. This provided a national needs assessment to serve as a basis for future instructional development in the area of effective teacher use of library media centers. Delphi and Fault Tree analysis were used in combination as the systematic methodology. A 58-item checklist was created from the Delphi phase of the study and the initial input from the national panel of experts was used to qualify a fault tree. The prime strategic path for effective teacher use of library media centers was determined to be ineffective use of existing learning resources because of failure to use production specialists effectively. The function of the production specialist was defined as using the specifications developed in the design function either to create resources or to locate appropriate existing materials. Other areas of study included inservice training, specifications of learning objectives, effective use of reference books, goals and policies about roles and purposes, evaluation, and selection of learning resources.
