This is the second of a two-part article that discusses the history of the field of instructional design and technology in theIn Part I of this article, I presented the following definition of the field of instructional design and technology:The field of instructional design and technology encompasses the analysis of learning and performance problems, and the design, development, implementation, evaluation and management of instructional and noninstructional processes and resources intended to improve learning and performance in a variety of settings, particularly educational institutions and the workplace. Professionals in the field of instructional design and technology often use systematic instructional design procedures and employ a variety of instructional media to accomplish their goals. Moreover, in recent years, they have paid increasing attention to noninstructional solutions to some performance problems. Research and theory related to each of the aforementioned areas is also an important part of the field. (Reiser, in press) As was pointed out in Part I, the major features of this definition include (a) its listing of six categories of activities or practices (analysis, design, development, implementation, evaluation, and management) often associated with the field; (b) its identification of research and theory, as well as practice, as important aspects of the profession; and (c) its recognition of the influence the performance technology movement has had on professional practices. Moreover, the definition highlights two practices that have, over the years, formed the core of the field. These two practices are (a) the use of media for instructional purposes and (b) the use of systematic instructional design procedures (often simply called instructional design). As was mentioned in Part I, although many have argued about the value of employing these practices, they remain as the key defining elements of the field of
