Many times it is not easy to achieve this on their own thus have to get aid from instructional models. Instructional models ensure that the teaching objectives are achieved at the end of the learning process. This paper examines some of the instructional design models.

Some of the common elements include; objective identification, defining content, designing instructions and presentation methods, syllabus development, evaluation and feed back (Ryder M, 2009). The major difference lies in the purpose of their design.

Most instructional models fall under reductionism; that is, they reinforce the desired behavior. They define objectives and develop instructional components to achieve the desired objectives. However, for effective learning, instructors should use progressive models such as the Gagne model which incorporates a collaborative learning process, with the students playing a major role.
