Cognitive theory focuses on what is going on inside the mind. It is more concerned with cognition (the process of thinking and learning)—knowing, perceiving, problem-solving, decision-making, awareness, and related intellectual activities—than with stimulus and response. Learning is not just a change in behavior; it is a change in the way a learner thinks, understands, or feels. Theories based on cognition are concerned with the mental events of the learner. Much of the recent psychological thinking and experimentation in education includes some facets of the cognitive theory.
Early theories of cognitive learning were established by psychologists and educators such as John Dewey, Jean Piaget, Benjamin Bloom, and Jerome Bruner. [Figure 2-3] Over the past century, there have been many interpretations of the increasingly large amount of research data dealing with cognitive theories. This has led to many different models for learning as well as catch phrases.
For example, educator, psychologist, and philosopher, John Dewey introduced the concept “reflective thought” in a 1910 book designed for teachers. Dewey believed learning improves to the degree that it arises out of the process of reflection. Over the years, terminology describing reflection has spawned a host of synonyms, such as “critical thinking,” “problem-solving,” and “higher level thought.”
For Dewey, the concept of reflective thought carried deep meaning. He saw reflection as a process that moves a learner from one experience into the next with deeper understanding of its relationships with and connections to other experiences and ideas. Thus, reflection leads the learner from the unclear to the clear. Jean Piaget, who spent 50 years studying how children develop intellectually, became a major figure in the school of cognitive thought. His research led him to conclude there is always tension between assimilation (old ideas meeting new situations) and accommodation (changing the old ideas to meet the new situations). The resolution of this tension results in intellectual growth. Thus, humans develop

cognitive skills through active interaction with the world (a basic premise of scenario-based training (SBT), discussed later in this chapter).
An American psychologist who studied with Piaget, Jerome Bruner became interested in how intellectual development related to the process of learning, His research led him to advocate learning from the known to the unknown, or from the concrete to the abstract, because humans best learn when relating new knowledge to existing knowledge. He introduced and developed the concept of the spiral curriculum, which revisits basic ideas repeatedly and builds on them in increasingly sophisticated ways as the student matures and develops.
Consider the opening scenario with Bill and Beverly. Bill might effectively use this theory with Beverly because she arrived at her first class with a store of aviation facts. Building upon this knowledge, Bill can teach her how to keep the aircraft in straight and level flight while he reinforces what she knows about basic aerodynamics via demonstration and discussion. Since aerodynamics is a constant thread in the flight lessons, Bill is also able to employ the spiral curriculum concept in future lesson by repeatedly revisiting the basic concepts and building upon them as Beverly’s skill and knowledge increase.
In the mid-1900s, a group of educators led by Benjamin Bloom tried to classify the levels of thinking behaviors thought to be important in the processes of learning. [Figure 2-4] They wanted to classify education goals and objectives based on the assumption that abilities can be measured along a continuum from simple to complex. The result, which remains a popular framework for cognitive theory, was Bloom’s Taxonomy of the Cognitive Domain. The taxonomy (a classification system according to presumed relationships) comprises six levels of intellectual behavior and progresses from the simplest to the most complex: knowledge, comprehension, application, analysis, synthesis, and evaluation. For more detailed information about the taxonomy, see Domains of Learning.
Continued research into cognitive theory has led to theories such as information processing and constructivism.
Information Processing TheoryInformation processing theory uses a computer system as a model for human learning. The human brain processes incoming information, stores and retrieves it, and generates responses to the information. This involves a number of cognitive processes: gathering and representing information (encoding), retaining of information, and retrieving the information when needed.
This learning system has limitations and must be operated properly. A computer gets input from a keyboard, mouse, etc., whereas the human brain gets input from the senses of sight, hearing, touch, taste, and smell. The amount of sensory input the brain receives per second ranges from thousands to millions of bits of information according to various theories. Regardless of the number, that is a lot of information for the brain to track and process.
