Providing a variety of instructional methods and materials, developing unique and effective communication systems, and continually evaluating the process are the keys to the effective delivery of field-based programs in graduate education offered by Nova University (Florida). It has become a leader in distance-education programs by offering off-campus undergraduate and graduate degree programs in education, business and public administration, psychology, and computer sciences. Almost half of the students are enrolled in field-based programs that are delivered in a number of ways, including the National Cluster approach of the doctoral program in Child and Youth Studies (CYS). The various forms of technology used for program delivery include the autobridge (a telephone technology), videotapes, audiotapes, telephone, electronic mail, and the electronic classroom (simultaneous online classes). A study of the effectiveness of the CYS National Cluster approach is being conducted to compare the effectiveness of its delivery methods and practicum approach (infrequent cluster meetings and more reliance on technology) with more traditional methods of distance education. Nova University recognizes the need to keep abreast of technology and to provide the latest valid delivery approaches for its distance learners. (Contains 5 references.) (SLD)
