Applied Research Laboratory at Penn State University defines Instructional Design as the systematic development of instructional specifications using learning and instructional theory to ensure the quality of instruction. It is the entire process of analysis of learning needs and goals and the development of a delivery system to meet those needs. It includes development of instructional materials and activities; and tryout and evaluation of all instruction and learner activities. There are numerous design models currently in use, including the ASSURE and Gerlach & Ely models.


When using the ASSURE model, the designer must begin by analyzing the learner. This analysis determines the learner's entry competencies, as well as, learning styles. Upon completion of the analysis, the designer will state the objectives. Learning outcomes, conditions of performance, and degree of acceptability are established at this stage of development. The designer will now select methods and media materials. The designer may choice to select available materials, modify existing materials, or design new materials. Once media materials are selected, the designer will preview and prepare the materials for instruction. The next step of the ASSURE model, requires learner participation through both in-class and follow-up activities. This allows the learner adequate time to process the information. The final step in this model, necessitates evaluation before, during, and after instruction. This allows for the assessment of both the learner, as well as, the media methods. The ASSURE model strengths consist of a well defined lesson  that progress through several stages that involves arousing the student’s interest, new material, allowing students to provide feedback, access the student’s understanding of the lesson and following up with the students. It promotes technology. The only  foreseeable ASSURE weakness is that it is time consuming to create for several lessons. 


The Gerlach & Ely model begins by synchronously determining the content and objectives. Ordinarily, the content is considered prior to the objectives, because in the classroom, content is typically predetermined, however, these steps can also be conducted simultaneously (Grabowski, 2003). Once content and objectives have been determined, the entry level skills and abilities are identified as a basis for determination of instruction. This is typical accomplished through review of records or the administration of a pre-assessment (Gerlach, 1980). The next step of this model is comprised of five fundamental elements that are interrelated. These elements include . To evaluate effectiveness, this linear model concludes with an evaluation and feedback loop (Prestera, 1997). Following the evaluation, instruction is modified to address the specific needs of instruction. 


Instructional models are models - they merely present a process. Whether selecting the ASSURE or the Gerlach & Ely model, the designer can be certain that both models provide an organized process in which all major learning components are considered. Regardless of the instructional model selectedsuccess is dependent on ongoing evaluation and revisions.
