David Ausubel is a psychologist who advanced a theory which contrasted meaningful learning from rote learning. In Ausubel's view, to learn meaningfully, students must relate new knowledge (concepts and propositions) to what they already know. He proposed the notion of an advanced organizer as a way to help students link their ideas with new material or concepts. Ausubel's theory of learning claims that new concepts to be learned can be incorporated into more inclusive concepts or ideas. These more inclusive concepts or ideas are advance organizers. Advance organizers can be verbal phrases (the paragraph you are about to read is about Albert Einstein), or a graphic. In any case, the advance organizer is designed to provide, what cognitive psychologists call, the "mental scaffolding: to learn new information.
Meaningful
Learning Non-arbitrary,
non-verbatim, substantive incorporation of new knowledge
into cognitive structure. Deliberate effort to
link new knowledge with higher order concepts in cognitive
structure Learning related to
experiences with events or objects. Affective commitment
to relate new knowledge to prior learning. Rote
Learning Arbitrary, verbatim,
non-substantive incorporation of new knowledge into
cognitive structure. No effort to
integrate new knowledge with existing concepts in cognitive
structure. Learning not related
to experience with events or objects. No affective
commitment to relate new knowledge to prior
learning.
Ausubel believed that learning proceeds in a top-down, or deductive manner. Ausubel's theory consists of three phases, presentation of an advance organizer, presentation of learning task or material, and strengthening the cognitive organization. The main elements of Ausubel's model are shown in Figure 2.34.
Phase One:
Advance Organizer Phase Two:
Presentation of Learning Task or Material Phase three:
Strengthening Cognitive Organization Clarify aim of the
lesson Present the
organizer Relate organizer to
students' knowledge Make the
organization of the new material explicit. Make logical order
of learning material explicit. Present material and
engage students in meaningful learning
activities. Relate new
information to advance organizer Promote active
reception learning.
Concept mapping for meaningful learning
Novak and Gowan (1984) have developed a theory of instruction that is based on Ausubel's meaningful learning principles that incorporates "concept maps" to represent meaningful relationships between concepts and propositions. A cognitive map is a "kind of visual road map showing some of the pathways we may take to connect meanings of concepts." According to Novak and Gowan concept maps should be hierarchical; the more general, more inclusive concepts should be at the top of the map, and the more specific, less inclusive concepts at the bottom of the map. An an example of this hierarchical principle of concept maps is shown in the concept map of the food chain.
The concept map is a tool that science teachers can use to determine the nature of students' existing ideas The map can be used to make evident the key concepts to be learned and suggest linkages between the new information to be learned and what the student already knows. Concept maps can precede instruction, and be used by the teacher to generate a meaningful discussion of student ideas. Following the initial construction and discussion of concept maps, instructional activities can be designed to explore alternative frameworks, resulting in cognitive accommodation.
