ABSTRACT

House (1993) defined evaluation as “the determination of the value or worth of something . . . judged according to appropriate criteria, with those criteria explicated and justified” (p. 1). Since the 1960s, the field of evaluation has expanded into a myriad of approaches, models, and persuasions (Cook, 1991; Cronbach, 1980, 1982; Eisner, 1976; Guba & Lincoln, 1989; House, 1980, 1993; Patton, 1990; Phillips, 1990; Popham, 1988; Provus, 1971; Rossi & Freeman, 1993; Scriven, 1969, 1974; Stake, 1983; Stufflebeam, 1966; Tyler, 1949). An array of analyses (Guba, 1990; House, 1983; Nevo, 1983; Patton, 1980; Scriven, 1983; Stake, 1983; Stufflebeam & Webster, 1980) have dissected, compared, and contrasted the numerous emergent and emerging models on a number of different points, including theoretical assumptions, ideologies, and political/social orientations.
