Instructional Theory and Instructional Design Theory: What's the difference and why should we care? Barbara A. Bichelmeyer, Ph.D Department of Instructional Systems Technology Indiana University The Instructor
The Instructional Designer
The context of instruction As a secondary school teacher, my years were spent teaching three courses per semester during six class periods a day to students ranging from 13 to 18 years of age. My students varied in their entry-level knowledge, their learning skills, their motivations for learning, and of course in their very personalities. The dynamics of group interactions were different in every class I taught. Consequently, what happened during each class period was unique and mostly unpredictable.
The context of instructional design When I was an instructional designer for a Fortune 100 telecommunications company, I spent very little time instructing or implementing lesson plans. Instead, I spent most of my time planning instruction that others would teach. As an instructional designer, my job was to create instructional designs that would be replicated over time, space, and various individuals. My work was to develop a course so that each instructor would teach it as I intended, so that different instructors would teach the course the same way, so that courses in different locations and environments would provide the same learning experiences to different students, and so that courses taught at different times would be delivered in similar fashion.
The objective of the instructor My objective as a teacher was to ensure that every student learned as much as possible about the subject, to the best of his or her abilities, knowing that each student would have reached a different achievement level by the end of the semester.
The objective of instructional design As an instructional designer, I was responsible for ensuring that any particular course taught to learners in different locations, at different times, by different instructors would be as similar as possible. My objective was to facilitate standardization of instruction by doing my best to account for variation between instructors, instructional locations, and instructional schedules.
The work of the instructor To achieve my objective, I manipulated the strategies of instruction: I concentrated on setting expectations, providing resources, presenting examples, facilitating practices, administering assessments, and giving feedback; I engaged in summative evaluation to understand what my students had learned. I spent a bit of time each day planning my lessons, but I spent much more time implementing them, adjusting as I went, and because of the uniqueness and unpredictability of my students, rarely did my plans work exactly as intended.
The work of the instructional designer In order to achieve my objective, I manipulated elements of the instructional design process: I analyzed the tasks that students were to learn, I analyzed the locations and timeframes of the instruction, I analyzed the characteristics of instructors as well as the characteristics of students; I looked for ways to design instructional and instructor materials so that they were most likely to be used by instructors and students; I struggled to develop instructor materials and instructional materials given constraints of budget, time, and human resources; I engaged in formative evaluation to see if the materials worked and I revised materials as necessary, based on findings from these evaluations.
The concerns of the instructor As an instructor, my greatest concerns were with variation and sufficiency; I worked to ensure that every lesson and activity was sufficiently targeted to meet the individual needs of each student, given the differences between members of each classroom group.
The concerns of the instructional designer As an instructional designer, my greatest concerns were with efficiency and standardization; I worked to ensure efficiency of both the instructional design process and the instructional product, and to provide standardized instruction to learners, given differences in time, location and instructors.
