Epistemology / Knowledge based theory of instructional design Prepared by: Soo Pei Zhi P-QM0033/10 QIM 501 Instructional Design and Delivery David Paul Ausubel (1918 – 2008) • An American psychologist, born in Brooklyn, New York. • Did his undergraduate work at the University of Pennsylvania (pre –med and psychology). • Graduated from medical school at Middlesex University. • Earned a Ph.D in Developmental Psychology at Columbia University. • Influenced by the work of Piaget. David Paul Ausubel (1918 – 2008) • His principal interests in psychiatry have been general psychopathology, ego development, drug addiction, and forensic psychiatry. • Served on the faculty at several universities and retired from academic life in 1973 and began his practice in psychiatry. • Published several textbooks in developmental and educational psychology, and more than 150 articles. • In 1976, he received the Thorndike Award for “Distinguished Psychological Contributions to Education” from the American Psychological Association. During meaningful learning, the person “subsumes,” or organizes or incorporates, new knowledge into old knowledge. Subsumption theory suggests that our mind has a way to subsume information in a hierarchical or categorical manner if the new information is linked/incorporated with prior knowledge/familiar patterns. As a result prior knowledge is given absolute importance. Teachers are encouraged to teach prior knowledge first rather than new information to help information subsume. Advance organizers provide concepts and principles to the students directly in an organized format. The strategy of “advance organizers” basically means to classify/ categorize/ arrange (organize) information as you proceed (advance) to the next complex level. 1 2 • The most general ideas of a subject should be presented first and then progressively differentiated in terms of detail and specificity. • Instructional materials should attempt to integrate new material with previously presented information through comparisons and cross-referencing of new and old ideas. • Helps introduce a new lesson, unit, or course. • Helps summarize major ideas in new lesson or unit. • Based on student’s prior knowledge. • Show similarities between old material and new material. • Allows student to transfer or apply knowledge. • Provides for structure for new information. • Helps teach complex material that is similar to information learned previously. Ausubel proposed four processes of meaningful learning: - Derivative subsumption - Correlative subsumption - Superordinate learning - Combinatorial learning New material or relationships can be derived from the existing structure. Information can be moved in the hierarchy, or linked to other concepts or information to create new interpretations or meaning. Example (Stage 1) • Suppose I have acquired a basic concept such as “tree” – trunk, branches, green leaves, and may have some kind of fruit. • Now, I learn about a kind of tree that I have never learn before “persimmon tree” – conforms to my previous understanding of tree. • My new knowledge of persimmon trees is attached to my concept of tree, without substantially altering that concept in any way. • So, I had learned about the persimmon trees through the process of derivative subsumption. New material is an extension or elaboration of what is already known. Example (Stage 2) • Suppose I encounter a new kind of tree that has red leaves, rather than green. • In order to accommodate this new information, I have to alter or extend my concept of tree to include the possibility of red leaves. • I have learned about this new kind of tree through the process of correlative subsumption. • In a sense, you might say that this is more “valuable” learning than of derivative subsumption, since it enriches the higherlevel concept. An individual is able to give a lot of examples of the concept but does not know the concept itself until it is taught. Example (Stage 3) • Imagine that I was well acquainted with maples, oaks, apple trees, etc., but I did not know, until I was taught, that these were all examples of deciduous trees. • In this case, I already knew a lot of examples of the concept, but I did not know the concept itself until it was taught to me. • This is superordinate learning. The first three learning processes all involve new information that "attaches" to a hierarchy at a level that is either below or above previously acquired knowledge. Combinatorial learning is different; it describes a process by which the new idea is derived from another idea that is neither higher nor lower in the hierarchy, but at the same level. Example (Stage 4) • Now, suppose I learn about how fish eggs are fertilized. • I might relate it to previously acquired knowledge about pollination in plants. • Both of the ideas are different, but it is related to the “process of breeding”. • You could think of this as learning by analogy. Advance organizers are used to relate prior information to new concepts. They are part of Ausubel's subsumption theory that "contends that meaningful learning and permanent retention of material is a function of the stability of existing anchoring ideas" (Applin). Can be classified : expository or comparative. While presenting new material. Use beginning of lesson. Presents several encompassing generalizations where detailed contents will be added later. Example • The teacher discuss the process of the absorption of water and minerals into the plants through the tap and fibrous root system. Useful when the knowledge to be presented is new to learner. Compares new material with knowledge already known by emphasizing the similarities between 2 types of material & showing the information that is to be learnt. Ausubel’s teaching approach is deductive in nature. Example • A teacher shows the similarities and differences among two major root system, the tap root and the fibrous root system. Ausubel’s theory is concerned with how individuals learn large amounts of meaningful material from verbal/ textual (lecture/ books) presentations in a school setting as opposed to theories developed based on experimental settings. Therefore, learning is based upon the kinds of superordinate, representational, and combinatorial processes that occur during the presentation of information.
