Theories of learning

Thomas Shuell :
Learning is one of the most important activities in which humans engage. It is at the very core of the educational process, although most of what people learn occurs outside of school. For thousands of years, philosophers and psychologists have sought to understand the nature of learning, how it occurs, and how one person can influence the learning of another person through teaching and similar endeavors. Various theories of learning have been suggested, and these theories differ for a variety of reasons. A theory, most simply, is a combination of different factors or variables woven together in an effort to explain whatever the theory is about. In general, theories based on scientific evidence are considered more valid than theories based on opinion or personal experience. In any case, it is wise to be cautious when comparing the appropriateness of different theories.
In addition to formal theories, people hold personal theories, including theories of learning and teaching. Some typical questions such theories might involve are: How does one determine if learning has occurred? What factors determine whether or not learning occurs? Are these factors located in the environment or within the individual?
This entry focuses first on different conceptions and definitions of learning. Next, the evolution of theories and conceptions of learning over the past 100 years is discussed, highlighting some of the advantages and limitations of different theoretical perspectives. Following a discussion of the relationship between theory and practice, examples of different types of learning are presented, and the appropriateness of different theories for different learning situations is pointed out.
Conceptions of “learning”
Understanding any theory requires a clear idea of what the theory is trying to explain. When a particular word is used, people usually assume everyone has a common understanding of what the word means. Unfortunately, such is not always the case. In trying to understand the various theories of learning and their implications for education, it is helpful to realize that the term “learning” means different things to different people and is used somewhat differently in different theories. As theories of learning evolved over the past half-century, definitions of learning shifted from changes that occur in the mind or behavior of an individual to changes in participation in ongoing activities with other individuals to changes in a person’s identity within a group (e.g., a change from being a follower to being a leader). Although, most definitions of learning involve a change in an individual’s knowledge, ability to perform a skill, or participate in an activity with other individuals, there is considerable variation among the theories about the nature of this change.
Further difficulty in understanding similarities and differences among various theories results from the frequently overlooked fact that there are different types of learning. In many cases, the various theories are relevant to different types of learning and are not necessarily incompatible with one another. Rather, they provide different perspectives on the complex phenomena of learning and complement one another in their ability to explain different types of learning situations. Thus, radically different theories are relevant to the classroom by addressing different aspects of classroom learning, and it is wise to avoid comparing apples with oranges. Examples of different types of learning are presented later in this entry.
Evolving theories of learning
The modern psychological study of learning can be dated from the work of Hermann Ebbinghaus (1850-1909), whose well-known study of memory was published in 1885. Other early studies of learning were by Edward L. Thorndike (1874-1949), whose dissertation on problem solving was published in 1898, and Ivan Pavlov (1849- 1936), whose research on classical conditioning was begun in 1899 but first published in English in 1927. These theories focused on explaining the behavior of individuals and became known as behavioral theories. These theories use a stimulus-response framework to explain learning and dominated psychology and education for over half a century. Because behavioral theories focus on environmental factors such as reinforcement, feedback, and practice, they conceptualize learning as something that occurs from the outside in.
Behavioral theories provide very good explanations for certain kinds of learning but poor explanations for other types of learning. Operant conditioning, for example, is better than other theories at explaining the rote acquisition of information, the learning of physical and mental skills, and the development of behaviors conducive to a productive classroom (i.e., classroom management). In these situations, the focus is on performing behavioral tasks rather than developing a learner’s cognitive structure or understanding. Although classical conditioning frequently is dismissed as irrelevant to human learning (Pavlov’s initial research paradigm involved dogs salivating), this type of learning provides by far the best explanation of how and why people, including students, respond emotionally to a wide variety of stimuli and situations. The many types of emotional reactions acquired through classical conditioning include: anger toward or hatred for a particular person or group, phobias to a particular subject area or to school itself, and infatuation with another person. However, they are very poor at explaining how individuals come to understand complex ideas and phenomena.
But environmental factors are not the only ones that influence learning. Serious consideration of other perspectives began to enter mainstream psychological thinking about learning during the 1960s. For example, people clearly learn by observing others, and a learner’s belief about his or her ability to perform a task (i.e., self-efficacy) plays an important role in their learning. In 1963 Albert Bandura and R. H. Walters published the first formal statement of social-learning theory in their book, Social Learning and Personality Development. Social-learning theory has clear roots in behavioral theory but differs from these theories in significant ways. During the 1980s the theory became known as social-cognitive theory. Although essentially the same theory, the new name more accurately reflects the cognitive features of the theory and aids in differentiating it from behavioral theories of learning.
During the 1970s and 1980s conceptions and definitions of learning began to change dramatically. Behavioral theories gave way to cognitive theories that focused on mental activities and the understanding of complex material. An information-processing metaphor replaced the stimulus-response framework of behavioral theories. These theories emphasized that learning occurred from the inside out rather than from the outside in. During the late 1970s John Flavell and Ann Brown each began to study metacognition-the learners’ awareness of their own learning, an ability to reflect on their own thinking, and the capacity to monitor and manage their learning. During the mid 1980s the study of self-regulated learning began to emerge (see Zimmerman & Schunk, 2001).
Then, especially during the later 1980s and the 1990s, these cognitive theories were challenged by theories that emphasized the importance of social interactions and the sociocultural context of learning. The work of the Russian psychologist Lev Vygotsky (1896-1934) first became available in North America and along with the work of anthropologists such as Jean Lave began to have a major influence on theories of learning. Individuals were seen as initially participating in peripheral activities of a group (known as legitimate peripheral participation)before becoming fully integrated into group activities. Apprenticeship became a metaphor for the way people learn in natural settings. The notion that people learn by observing others, first articulated in social-cognitive theory, was expanded in a new context.
Traditionally, learning has been viewed as something that occurs within an individual. Individuals may participate and learn in groups, but it is the individual person that learns. With few exceptions, the educational systems in Europe and North America have adopted this perspective, if not entirely with regard to instructional practices, certainly in the evaluation of student performance and the assignment of grades. Many psychologists and educators currently consider learning to be a phenomenon that is distributed among several individuals and/or environmental affordances (such as calculators, computers, and textbooks) or situated (existing or occurring) within a “community of practice” (or community of learners). Both a social and a material dimension are involved in this distribution (Pea, 1993). For example, a student may use a calculator to help learn how to solve a three-digit multiplication problem (the material dimension) and/or work with another student to understand the proper procedures to follow (the social dimension). In either case, the student is not learning totally on his or her own but is taking advantages of resources (affordances) available in the environment. If the student is not able to solve a subsequent problem without the aid of the calculator or another student, then it is possible to see the distributed nature of learning. In such situations, participation or activity rather than acquisition becomes the defining metaphor (Greeno, 2006).
The evolution from behavioral to social to distributed to situated theories of learning was accompanied by new conceptions of knowledge (for a good discussion of these changes, see Schraw, 2006). Traditional theories conceive of knowledge as a commodity capable of being transmitted, more or less intact, from one individual to another. According to these theories, knowledge is something an individual acquires; when a student successfully learns it, he or she can reproduce the knowledge in its original form. In contrast, more recent theories conceive of knowledge as something each learner constructs or creates afresh rather than something that is assimilated in its preexisting form. According to current theories, truly “objective” knowledge does not exist, although something similar exists in the form of collective knowledge within a particular culture or discipline. Knowledge resides in the community of learners (individuals) that creates it and is distributed among members of the community and the various environmental affordances available to the group. Because each person constructs his or her own understandings, the knowledge they acquire is unique. Communities and cultures are composed of individuals with common understandings, and these groups provide opportunities for new members (e.g., children) to construct similar knowledge of the world through schools and/or a variety of informal activities.
