"- A major goal of schooling is to prepare students for flexible adaptation to new problems and settings.
- The ability of students to transfer provides an important index of learning that can help teachers evaluate and improve their instruction. However, much testing only measures learning as memory for information rather than mastery.
- Instructional differences become more apparent when evaluated from the perspective of how well the learning transfers to new problems and settings.
- Several critical features of learning affect people's abilities to transfer what they have learned.
- Opportunities to use knowledge to create products and benefits for others are particularly motivating for students.
- Time spent learning for understanding has different consequences for transfer than time spent simply memorizing facts or procedures from textbooks or lectures.
-In order for learners to gain insight into their learning and their understanding, frequent feedback is critical: students need to monitor their learning and actively evaluate their strategies and their current levels of understanding.
- Knowledge that is taught in only a single context is less likely to support flexible transfer than knowledge that is taught in multiple contexts.
- Using multiple contexts, students are more likely to abstract the relevant features of concepts and
develop a more flexible representation of knowledge
- The use of well-chosen contrasting cases can help students learn the conditions under which new
knowledge is applicable.
- Abstract representations of problems can also facilitate transfer.
-In assessing learning, the key is increased speed of learning the concepts underlying the new material.
- All new learning involves transfer.
-Previous knowledge can help or hinder the understanding of new information.
- Teachers can help students change their original conceptions by helping students make their thinking visible so that misconceptions can be corrected and so that students can be encouraged to think beyond the specific problem or to think about variations on the problem.
- One aspect of previous knowledge that is extremely important for understanding learning is cultural practices
that support learners' prior knowledge.
-Effective teaching supports positive transfer by actively identifying the relevant knowledge and strengths that
students bring to a learning situation and building on them
- Transfer from school to everyday environments is the ultimate purpose of school-based learning.
- An analysis of everyday environments provides opportunities to rethink school practices in order to bring them into alignment with the requirements of everyday environments; however, it is important to avoid instruction that is overly dependent on context.
-Helping learners choose, adapt, and invent tools for solving problems is one way to facilitate transfer while also encouraging flexibility.
- A metacognitive approach to teaching can increase transfer by helping students learn about themselves as learners in the context of acquiring content knowledge.
"Over 400 years before the birth of Christ, philosophers began their deliberations on the nature of thinking and learning. Using the only method available at the time, logical analysis, they developed explanations of the ways in which human beings acquire knowledge. However, the information developed is often limited in nature because only gen-
eral questions are asked.

The importance of experimentation in developing knowledge
about the physical sciences was demonstrated by Galileo in the 16th century. However, research on the mind was delayed for some 300 years until an acceptable rationale was developed for subjecting a gift of God to research. Both Darwin's concept of evolution and Helmholtz's discovery of many basic facts about sight and hearing set the stage for
psychological research.

The separation of psychology from philosophy was initiated by Wilhelm Wundt in his 1874 text on physiological psychology. His experimental laboratory, established 5 years later, drew individuals from many nations, including the United States. In less than 20 years, psychological research was firmly established in several American universities.
The chief architects of American psychology—William James, John Dewey, G. Stanley Hall, and Edward Thorndike —forged a dynamic new science responsive to issues in both human life and education. James provided the rationale for a functional psychology and gave the discipline a broad knowledge base in his two-volume text. He also translated his views into guidelines for teachers. Dewey and Hall provided leadership for school reform. Dewey saw the school as the mechanism for reforming a society that must adjust to the industrial revolution. Education should develop knowledgeable citizens, and the emphasis should be on personal experimentation, planning, and reinvention by the child.

Dewey's views became the rallying cry for educational reformers seeking to change the school. Hall, in contrast, emphasized the use of data about children in planning curriculum. His views initiated the child-study movement.

Edward Thorndike exemplified the educational scientist working to improve education. His innovative dissertation study established the first learning theory and demonstrated the feasibility of behavioral research in generating information about learning. His work initiated both the scientific movement in education and educational psychology.
"The concept of " development" is critical to understanding the changes in children's thinking, such as the development of language, causal reasoning, and rudimentary mathematical concepts. Young children are actively engaged in making sense of their worlds. In some particular domains, such as biological and physical causality, number, and language, they have strong predispositions to learn rapidly and readily.

These predispositions support and may even make possible early learning and pave the way for competence in early schooling. Yet even in these domains, children still have a great deal of learning to do. Children's early understanding of the perceptual and physical world may jump-start the learning process, even making learning possible, but one should look with caution for ways in which early knowledge may impede later learning. For example, children who treat rational numbers as they had treated whole numbers will experience trouble ahead. Awareness of these roadblocks to learning could help teachers anticipate the difficulty. Although children learn readily in some domains, they can learn practically anything by sheer will and effort. When required to learn about nonprivileged domains they need to develop strategies of intentional learning.

In order to develop strategic competence in learning, children need to understand what it means to learn, who they are as learners, and how to go about planning, monitoring, revising, and reflecting upon their learning and
that of others. Children lack knowledge and experience but not reasoning ability. Although young children are inexperienced, they reason facilely with the knowledge they have. Children are both problem solvers and problem generators: children attempt to solve problems presented to them, and they also seek novel
challenges. They refine and improve their problem-solving strategies not only in the face of failure, but also by building on prior success. They persist because success and understanding are motivating in their own right.
Adults help make connections between new situations and familiar ones for children. Children' s curiosity and persistence are supported by adults who direct their attention, structure their experiences, support their learning attempts, and regulate the complexity and difficulty levels of information for

Children, thus, exhibit capacities that are shaped by environmental experiences and the individuals who care for them. Caregivers provide supports, such as directing children's attention to critical aspects of events, commenting on features that should be noticed, and in many other ways providing structure to the information. Structure is critical for learning and for moving toward understanding information. Development and learning are not two parallel processes. Early biological underpinnings enable certain types of interactions, and through various environmental supports from caregivers and other cultural and social supports, a child's experiences for learning are expanded. Learning is promoted and regulated both by children' s biology
and ecology, and learning produces development.
"It is often popularly argued that advances in the understanding of brain development and mechanisms of learning have substantial implications for education and the learning sciences. In addition, certain brain scientists have offered advice, often with a tenuous scientific basis, that has been incorporated into publications designed for educators (see, e.g., Sylwester, 1995:Ch. 7). Neuroscience has advanced to the point where it is time to think critically about the form in which research information is made available to educators so that it is interpreted appropriately for practice— identifying which research findings are ready for implementation and which are not.
This chapter reviews the evidence for the effects of experience on brain development, the adaptability of the brain for alternative pathways to learning, and the impact of experience on memory. Several findings about the brain and the mind are clear and lead to the next research topics:

1. The functional organization of the brain and the mind depends on and benefits positively from experience.
2. Development is not merely a biologically driven unfolding process,
but also an active process that derives essential information from experience.
3. Research has shown that some experiences have the most powerful effects during specific sensitive periods, while others can affect the brain over a much longer time span.
4. An important issue that needs to be determined in relation to education is which things are tied to critical periods (e.g., some aspects of phonemic perception and language learning) and for which things is the time of
exposure less critical. From these findings, it is clear that there are qualitative differences among kinds of learning opportunities. In addition, the brain " creates" informational experiences through mental activities such as inferencing, category formation, and so forth. These are types of learning opportunities that can be facilitated. By contrast, it is a bridge too far, to paraphrase John Bruer (1997), to suggest that specific activities lead to neural branching (Cardellichio and Field, 1997), as some interpreters of neuroscience have implied.
"The word attention is heard often in educational settings. Teachers and parents complain that students do not pay attention to instructions or directions. (This does not seem to be the problem in the opening scenario; rather, the issue involves meaningfulness of processing.) Even high-achieving students do not always attend to instructionally relevant events. Sights, sounds, smells, tastes, and sensations bombard us; we cannot and should not attend to them all. Our attentional capabilities are limited; we can attend to a few things at once. Thus, attention can be construed as the process of selecting some of many potential inputs.

Alternatively, attention can refer to a limited human resource expended to accomplish one's goals and to mobilize and maintain cognitive processes (Grabe, 1986).

Attention is not a bottleneck in the information processing system through which only so much information can pass. Rather, it describes a general limitation on the entire human information processing system.
Attention is a necessary prerequisite of learning. In learning to distinguish letters, a child learns the distinctive features: To distinguish b from d, students must attend to the position of the vertical line on the left or right side of the circle, not to the mere presence of a circle attached to a vertical line. To learn from the teacher, students must attend to the teacher's voice and ignore other sounds. To develop reading comprehension skills, students must attend to the printed words and ignore such irrelevancies as page size and color.

Attention is a limited resource; learners do not have unlimited amounts of it. Learners allocate attention to activities as a function of motivation and self-regulation (Kanfer & Ackerman, 1989, Kanfer & Kanfer, 1991). As skills become routine, information processing requires less conscious attention. In learning to work multiplication problems, students must attend to each step in the process and check their computations. Once students learn multiplication tables and the algorithm, working problems becomes automatic and is triggered by the input. Research shows that much cognitive skill processing becomes automatic (Phye, 1989).
"We forget a lot despite our best intentions. Forgetting refers to the loss of information from memory or to the inability to access information. Researchers disagree about whether information is lost from memory or whether it still is present but cannot be retrieved because it has been distorted, the retrieval cues are inadequate, or other information is interfering with its recall. Forgetting has been studied experimentally since the time of Ebbinghaus (Chapter 1). Before presenting information processing perspectives on forgetting, which involve interference and decay, some historical work on interference is discussed.

-Interference Theory
According to this theory, learned associations are never completely forgotten. Forgetting results from competing associations that lower the probability of the correct association being recalled; that is, other material becomes associated with the original stimulus (Postman, 1961). The problem lies in retrieving information from memory rather than in memory itself (Crouse, 1971). Two types of interference were experimentally identified (Table 5.3). Retroactive interference occurs when new verbal associations make remembering prior associations difficult. Proactive interference refers to older associations that make newer learning more difficult.

-Information processing
Interference refers to a blockage of the spread of activation across memory networks. One factor that can affect whether structures are activated is the strength of original encoding. Information that originally is strongly encoded through frequent rehearsal or extensive elaboration is more likely to be accessed than information that originally is weakly encoded. A second factor is the number of alternative network paths down which activation can spread (Anderson, 1990). Information that can be accessed via many routes is more likely to be remembered than information that is only accessible via fewer paths.
"Without going into the details of the radical change of epistemological perspective inherent in the move to constructivism, I want to suggest that there are certain circumscribed areas in which a constructivist orientation can modify a teacher's attitude. It could, for instance, bring home the realization that students perceive their environment in ways that may be very different from those intended by the educators. And this environment includes curricula, textbooks, didactic props including computer programs and micro worlds, tasks they are given, and, of course, the teachers. This emphasizes the teacher's need to construct a hypothetical model of the particular conceptual worlds of the students they are facing. One can hope to induce changes in their ways of thinking only if one has some inkling as to the

domains of experience, the concepts, and the conceptual relations the students possess at the moment (cf. von Glasersfeld & Steffe, 1991). Similarly, the consideration of how meanings are constituted, and how, consequently, linguistic communication works, would dismantle the still widespread notion that conceptual knowledge can be transferred from teacher to student by the means of words. This is not to say that language is not important. In fact, it is the most powerful tool available to the teacher, but it does not transport meanings or concepts. Language enables the teacher to orient the student's conceptual construction by precluding certain pathways and making others more likely.

These are only two facets of the constructivist model, but they go a long way toward establishing the fundamental principle that learning is a constructive activity that the students themselves have to carry out. From this point of view, then, the task of the educator is not to dispense knowl-
edge but to provide students with opportunities and incentives to build it up.
"The concept of adaptation stems from biology, and it indicates a particular relationship between living organisms or species and their environment.

To say that they are adapted means no less but also no more than that they have been able to survive given the conditions and the constraints of the world in which they happen to be living. In other words, they have managed to evolve a fit or, as I prefer to say, their physical characteristics and their ways of behaving have so far proven viable in their environment.

Piaget took the notion of adaptation out of the biological context and turned it into the cornerstone of his genetic epistemology. He had realized early on that whatever knowledge was, it was not a copy of reality. The relationship of viable biological organisms to their environment provided a means to reformulate the relationship between the cognitive subject's conceptual structures and that subject's experiential world. Knowledge, then, could be treated not as a more or less accurate representation of external things, situations, and events, but rather as a mapping of actions and conceptual operations that had proven viable in the knowing subject's experience.

The use Piaget makes of the notion of adaptation is therefore not the same as that suggested by the contemporary school of thought that goes by the name of evolutionary epistemology. Unlike this school, which formed around the work of Konrad Lorenz, in Piaget's constructivist theory one cannot draw conclusions about the character of the real world from an organism's adaptedness or the viability of schemes of action. In his view, what we see, hear, and feel—that is, our sensory world—is the result of our own perceptual activities and therefore specific to our ways of perceiving and conceiving. Knowledge, for him, arises from actions and the agent's reflection on them. The actions take place in an environment and are grounded in and directed at objects that constitute the organism's experiential world, not things in themselves that have an independent existence. Hence, when Piaget speaks of interaction, this does not imply an organism that interacts with objects as they really are, but rather a cognitive subject that is dealing with previously constructed perceptual and conceptual structures.
"Experimental investigation of the egocentric speech of children engaged in various activities such as that illustrated by Levina produced the second fact of great importance demonstrated by our experiments: the relative amount of egocentric speech, as measured by Piaget's methods, increases in relation to the difficulty of the child's task.14 On the basis of these experiments my collaborators and I developed the hypothesis that children's egocentric speech should be regarded as the transitional form between external and internal speech. Functionally, egocentric speech is the basis for inner speech, while in its external form it is embedded in communicative speech.

One way to increase the production of egocentric speech is to
complicate a task in such a way that the child cannot make direct use of tools for its solution. When faced with such a challenge, the children's emotional use of language increases as well as their efforts to achieve a less automatic, more intelligent solution. They search verbally for a new plan, and their utterances reveal the close connection between ego-
centric and socialized speech. This is best seen when the experimenter leaves the room or fails to answer the children's appeals for help. Upon being deprived of the opportunity to engage in social speech, children immediately switch over to egocentric speech.

While the interrelationship of these two functions of language is apparent in this setting, it is important to remember that egocentric speech is linked to children's social speech by many transitional forms.

The first significant illustration of the link between these two language functions occurs when children find that they are unable to solve a problem by themselves. They then turn to an adult, and verbally describe the method that they cannot carry out by themselves. The greatest change in children's capacity to use language as a problem-solving tool takes place somewhat later in their development, when socialized speech (which has previously been used to address an adult) is turned inward.

Instead of appealing to the adult, children appeal to themselves; language thus takes on an intrapersonal function in addition to its interpersonal use. When children develop a method of behavior for guiding themselves that had previously been used in relation to another person, when they organize their own activities according to a social form of behavior, they succeed in applying a social attitude to them-
selves. The history of the process of the internalization of social speech is also the history of the socialization of children's practical intellect.
To summarize what has been said thus far in this section: The specifically human capacity for language enables children to provide for auxiliary tools in the solution of difficult tasks, to overcome impulsive action, to plan a solution to a problem prior to its execution, and to master their own behavior. Signs and words serve children first and foremost as a means of social contact with other people. The cognitive and communicative functions of language then become the basis of a new and superior form of activity in children, distinguishing them from animals.
Unlike behaviorism and cognitive theories that believe the world is real, external to the learner and the goal of instruction is to map the structure of the world to the learner, a recent constructivist approach (a branch of cognitive theory) believes knowledge is a function of how the individual creates meaning from his or her experiences. Constructivists believe that learning happens when meaning is made from experience. Constructivists believe the mind filters input from the world the produce its own unique reality. The mind is believed the be the source of all meaning, and direct experiences with the environment is critical. Constructivism crosses both categories by emphasizing the interaction between these two variables. Constructivists do not believe knowledge is mind-independent and can be mapped to the learner. Constructivists do not deny the existence of the real world, but contend that we know of the world stems from our own interpretations of our experiences. Humans create meaning as opposed to acquiring it. Because there are many meanings to gain from any experience, we cannot achieve a predetermined correct meaning. Learners do not transfer knowledge from the eternal world into their memories, rather they build personal interpretations of the world based on individual experiences and interactions. Thus, the internal representation of knowledge is constantly open to change. There is no real objective reality that learners strive to know. Knowledge emerges in contexts within which it is relevant. Therefore in order to understanding the learning which has taken place within an individual, the actual experience must be examined. The interaction between learners and environmental factors creates knowledge in the constructivist perspective.
"The article looks at behaviorism, cognitive theory, and constructivism. Constructivism has recently been emphasized instructional design literature. All three theories overlap but are distinctive enough to be treated as separate approaches to understanding and describing learning. These perspectives were chosen because of their historical influence and their contributions to instructional design. The additional questions help readers to understand and make recommendations from the application of these principles in the design of instruction. -individual vs. shared cognition
-pure mentation vs. tool manipulation
-symbol manipulation vs contextualized reasoning
-generalized learning vs. situational specific competencies
-school and economic participation
-Skills for outside school
-civic and cultural functions of education

Schools are social constructs based on cultural aspects of the school, where it is physically located who attends it, who teaches at it, what is taught.

Resnick's principles focus our attention on the teacher and the student and how language is used as a cultural tool to mediate learning. She considers the role of schooling in the preparation of individuals in terms of three broad areas: (a) participating in the economic society; (b) being a life-long learner in relation to their work; and (c) participating in civic and cultural realms of society. Resnick's (1987) work builds on Vygotsky's (1978) central premise that social interaction is pivotal to how language and signs are used to help socially construct knowledge. Resnick's (1987) comparison of in-school and out-of-school learning helps to frame how the more authentic usage of language in out-of-school contexts better supports learning as it serves a "real" and functional purpose.

Gee (2008) posits that students' opportunity to learn (OTL) and how we assess learning are key areas of concern. In reviewing the traditional and sociocultural perspectives of learning, Gee reminds us of the dynamic nature of learning. According to Gee (2008) learning is never exactly the same because the people, the signs, and the moment in time all impact learning as it happens.

It is the language and use of signs between the learner and the more advanced peer or teacher that facilitates new knowledge for the individual. The social context is paramount to the learning experience. Gee highlights the benefits of the sociocultural view over a more traditional view of learning as mental representations held in a person's mind. According to this perspective, students have the potential to engage with affordances or action possibilities. According to this theory, learning occurs only when the learner is able to interact with the learning objects; that is, learners must have an OTL given their capabilities and learning potential within the environment.
Gee ends his discussion with five rights each child has with regard to OTL that instructional designers must take into account when providing opportunities to learn. We extend this concept to learning in a broad sense and to the myriad of ways that we are responsible for facilitating learning in our professional domains.

Gee challenged us to ensure that students are afforded an opportunity to learn by ensuring rich learning context that build on learners' funds of knowledge
"We have used the distinction that DeCorte et al. (1996) draw
between the first and second waves of the cognitive revolu-
tion to organize our discussion of the cognitive and situated
perspectives. Our purpose in doing so was to clarify differ-
ences in the use of key terms by relating them to differences
in the underlying metaphors of the two theoretical perspectives. In the course of the discussion, we also developed our own position and differentiated it from some of the claims made in the name of situated learning theory. For example, we concurred with Anderson et al.'s (1996) argument that many of the instructional recommendations made in the name of situated learning theory are unsubstantiated. However, we questioned Anderson et al.'s assumption that these erroneous recommendations can be traced back to basic theoretical commitments. We instead suggested that the practice of translating basic theoretical tenets directly into instructional prescriptions involves a category error. The deeper issue is the relationship between theory and practice, and here we also critiqued the positivist stance taken by Anderson et al. (1997). Regarding the alternative view we developed, we would acknowledge that the reflexive relation between theory and practice implicit in our classroom-based research activity is itself situated. In this regard, we agree with Nuthall's (1996) contention that

differences between theories of classroom learning ... re-
flect differences in the paradigm that researchers have in
mind as they think about how their research relates to
classroom practice and theory. The evolution of research
and theory is itself a sociocultural activity shaped by the
working relationships that researchers establish with
those whose lives and experiences they study and whose
lives and experiences they hope to influence. (p. 6)

A second point on which we differ with some of the more uncompromising versions of situated learning theory follows from our discussion of units of analysis. We described the theoretical approach that has emerged in the course of
our work in which we view students' reasoning as nec-
essarily situated while simultaneously attending to qual-
itative differences in the ways that they participate in
communal practices. We therefore have difficulty with epistemological behaviorist positions that identify meaning exclusively with use and limit their focus to observed social
activity. By the same token, however, we questioned the
treatment of meaning in Anderson et al.'s (1996) cognitive
perspective. For our purposes, it is essential to go beyond
cognitive behavior by analyzing the quality of students' inferred, socially situated mathematical experience. As we
noted, the distinction between these two perspectives'
treatments of mathematical meaning corresponds to that
which MacKay (1969) makes between the observer's and
the actor's viewpoints. Our strong preference for the actor's

Viewpoint is rooted in our activity as researchers who co-participate in the learning-teaching process with teachers and their students. As Rommetveit (1992) and Schutz (1962) both emphasize, to co-participate is to engage in communicative interactions that involve a reciprocity of perspectives characteristic of the actor's viewpoint.position does not demonstrate that it is wrong in the sense that it somehow fails to capture the essence of individual and collective human activity. Instead, our central claim has been that the characterizations of meaning and learning that this perspective offers do not address our concerns as classroom-based researchers and instructional designers.

We readily acknowledge that this theoretical orientation
might well be appropriate for other purposes such as de-
signing expert systems or supporting the development of
competent performance on a clearly delineated range of
tasks. Further, in light of the numerous references that Anderson et al. (1996) make to empirical findings, we accept
that the cognitive perspective might be judged to be pro-

A second point on which we differ with some of the more
In closing, we stress that our critique of Anderson et al.'s
gressive when assessed in terms of its own internal criteria.

We do, however, question whether it has made significant
progress in recent years on issues that are relevant to those
of us who conduct classroom-based research and instruc-
tional design. In general, the conclusions we have reached
are less generous than those of Greeno (1997), who speaks
of exchanges between cognitive and situated learning the-
orists spurring the development of more comprehensive
theories of learning. The contrast in Greeno's and our views
on the potential contributions of the cognitive perspective
appears to reflect our concerns as members of different re-
search communities.
"The goal of the recommended research and development in this area is to build on and elaborate findings in this volume so that they are "applications ready" and more usable to those responsible for developing curriculum, instructional, and assessment materials. The intent is to achieve three interrelated goals: (a) to identify existing educational materials that are aligned with the principles of learning suggested in earlier chapters and to develop and test new materials in areas of need; (b) to advance the knowledge base by significantly extending the work described herein to additional areas of curriculum, instructional techniques, and assessments that are in need of detailed analysis; and (c) to communicate the messages of this volume in a manner appropriate to developers of educational materials and teachers by using a variety of technologies (e.g., texts, electronic databases, interactive web sites). The recommended research is described in this section in seven project areas.
1.Examine existing practice
2. Extend knowledge base by developing and testing new educational materials
3. Extend the knowledge base through elaboration and development of key research findings.
4. Develop tools for effective communication of the principles of learning as they apply to educational materials
5. Examine existing practice through the lens of this volume
6. Extend the knowledge base through elaboration and development of key research findings
7. Develop tools for Effective communication of the principles of learning to teacher education.

The goal restated:
(a) to look first at existing practice through the lens of this volume, (b) to advance understanding in ways that would facilitate alignment of teacher preparation with principles of learning, and (c) to make the findings of this research more widely accessible and easily understood.
"Learning science is interdisciplinary in nature. It is holistic and eclectic. It draws from a myriad of fields like education, instructional design, computer design, constructivism, and cognitive science. These fields combine in a way that allow for a multifaceted approach to comprehensively explain how people learn in both formal and informal settings and the cognitive and social processes that best support effective learning.

Since the beginning of the modern institution of schools, there has been debate about whether education is a science or an art. The language of science makes some educators nervous. Everyone can remember the artistry of a great teacher - a teacher who somehow against all odds got every student to perform better than they thought they could. Teachers themselves know how complex their job is - every minute of every hour, a thousand different things are going on, and it can seem so unlikely that the cutting-and-slicing reductionist approach of science could ever help us understand what's happening. The history of scientific approaches to education is not promising; in the past, scientists studied learning in a university laboratory and then delivered pronouncements from the Ivory Tower that teachers were expected to adopt unquestioningly (Cremin, 1961).

Unlike these previous generations of educational research, learning scientists spend a lot of time in schools - many of us were full-time teachers before we became researchers. And learning scientists are committed to improving classroom teaching and learning - many are in schools every week, working directly with teachers and districts. Some even take time off from university duties and return to the classroom, teaching alongside teachers and learning how to make theories work in the real world. This is a new kind of science, with the goal of providing a sound scientific foundation for educational innovations including
