Learning Theory: Summary Statements

Learning Theory: Grappling with the Theory/Pracice Nexus in Search of a Viable Praxis

As I read through these theoretical papers, I feel the professional academics get to dream as big as they want to, but the actual classroom teacher is the real life practitioner who takes what might be great in theory and translates what she can into her actual working situation.

This viewpoint, expressed so succinctly by one class participant in my current seminar on adult education curriculum theory, carries a great deal of resonance with others in the course as one of the critical themes that come across in the discussion posts. As one both immersed in 20+ years of daily practice as well as extensive theoretical explorations underlying adult literacy education, I also experience a good deal of angst in any effort that attempts to resolve the theory/practice tension so pervasive in educational discourse. The issue, as I see it, is less that one (theory) is idealistic and the other (practice) is realistic, since they each combine theoretical reflection and insight from the field in their various ways.

The issue as I see it is that academic theory and grounded practice have their basis in divergent discourse communities with different focused objectives, which have the capacity to converge in places, yet perhaps less often than what may be viewed as desirable from both the perspective of the theorist and the practitioner. I believe that this tension has its origins in western epistemology (how we learn) grounded in the founding texts of Plato in positing an ineradicable gap between the ideal and real, a polarity which has never stopped resonating in many conscious and unconscious ways. Given this assumption, I do not think there can be any straight-forward resolution of the theory/practice tension in contemporary educational discourse, in which, however, the dynamic relation between theory and practice offers much potential fruit for new learning for practitioners and formal theorists alike.

Bringing this closer to home, the tension between theory and practice in education would be broadly akin to that between the theoretical scientist and the engineer or the medical practitioner, whose primary purpose is that of building better bridges or practicing more effective medicine. In the process of carrying out their work, the engineer or medical profession may draw on core scientific precepts in grappling with a particular problem such as what drug (if any) to prescribe to a given patient, what dose, and for what exact purpose. Many variables about the patient’s own medical history in its potential interaction with the drug would need to be factored in. It is in working through direct application issues as indicated in the example in which the latest scientific journal article may convey to the medical practitioner that missing piece of information which may simply not be available through direct observation or dialogue with the patient, whether a new conceptual insight or a new mode of application.

In this respect the highly informed medical professional brings together information from both worlds (the scientific based journals and sound medical practice honed through years of practice). Such competency is further developed through detailed work with hundreds of patients, substantial comparative analysis of critical cases in one’s chosen sub-field, through discussions with colleagues, in attending special seminars, and in studying the academic medical journals with keen discernment in probing for relevant information, some of which may or may not be immediately germane to one’s current practice.

Thus, the highly informed medical practitioner keeps attuned to theoretical discussion and research relevant to his or her practice, though typically draws on it to work through some practitioner-based issue or problem. I say typically, because through knowledge gained in drawing on theory or research in application to a specific issue or patient, the practitioner could and sometimes does, contribute to the broader pool of knowledge of her/his field by addressing theory/research questions from the local of one’s grounded location. While such efforts are far from typical, they do point to a potentiality in the theory/practitioner continuum that could reap much value. Mediating efforts include participating on research teams or writing in a way that addresses theory/research issues in more practitioner-based publications.

In moving to our more immediate focus on adult education practice, the keen insights that we have shared on learning theory and its relevance to our own work provide a rich baseline of ideas that will need to be more thoroughly processed in the shaping up of revised and new curriculum designs in our own specific teaching contexts and integrate into the various topics we are studying. A summary of the key the key ideas raised these past three weeks include the following:

1. At some level theory matters in that ideas are incorporated into practice by definition and therefore cannot be avoided. On this assumption theory construction in some formal or informal level is part of the essential work of both the practitioner and the academic specialist and takes place all the time regardless as to our awareness as to how they are playing out in our own practice.

2. Better to be informed, therefore, of one’s implicit and explicit theoretical assumptions as they are enacted in our practice in order to better grasp, and also to modify or, as the situation may call for, even to more fundamentally alter some of the core presuppositions of our work if to do so leads to better practice.

3. Some of us have identified key theoretical breakthroughs in identifying or altering our teaching or program-based practice.

a. Some have referred to the importance of Malcolm Knowles work on the self-directed learner and the focus in adult education on practical relevance through a facilitative pedagogy, which Knowles refers to as andogogy. Knowles’ insights might be aptly viewed as a blending of humanistic philosophy and constructivist learning theory.

b. Many have referred to the importance of constructivism as central to adult education practice while realizing that in certain task-based contexts or in contexts where automaticity is crucial, other theoretical emphases may be more relevant. As pointed out in many of your postings, much of the critical work of the discerning practitioner is to deftly apply specific aspects of theoretical insights to particular pedagogical challenges which we encounter daily in our programs.

c. I have sought to bring to the fore the central role of Dewey’s concept of “growth” in providing an imaginative schema in grounding my understanding of a “middle-ground” practice which opened up a significant interpretive lens on both my daily work as a site based adult literacy program manager and formal theory construction. Dewey’s learning theory has been a central thread of progressive educational thought throughout the 20th century and has much, though largely untapped potential in enhancing adult education thought and practice.

4. Some wonder about the relevance at all of possessing formal knowledge of established learning theories in that some of the most highly competent teachers practice their craft with keen intuitive insight and a solid knowledge base honed by years of practice, with very little formal theoretical understanding of the pedagogy informing their work. On this I offer the following:

a. While there are important and potentially useful relationships between academic learning theory and best practices they are not tightly correlated. Rather, theory, like instructional materials are a resource that the savvy practitioner utilizes to better inform her or his practice. In this respect, knowledge of academic learning theory becomes relevant to the extent that it offers valuable resources and insight to effectively enhance practice in any given context. In this respect, the well grounded teacher draws on theory in a manner analogous to the skilled engineer rather than in the mode of the research scientist. In either case sound principles apply, but the one does so to further refine discussions on theory while the other does so to improve practice. Both are valuable; both are necessary. Sometimes there is nothing more practical than a good theory. Sometimes there is nothing more practical than better practice.

b. Resources gleaned from constructivist learning theory are generally more useful (a) when the important instructional work at hand is helping students to strengthen their own internal representations as knowledgeable learners, (b) when the topic matter is focused more on empathetic and critical probes into different points of view or based primarily on self-reflection and building empathetic communities of learners. Still, as pointed out, constructivism may play a significant role in providing an underlying tone in learning challenges that are primarily focused on mastering sequential tasks and developing automaticity in developing greater phonemic awareness. That is, while a task may call for a mastery of sequential steps, issues related to internal representation and motivation still may require constructivist insight in linking a particular learning style and history with a progressive mastery of a given task at hand. These are subtle matters that require a great deal of discernment in which we often learn through the inevitability of our mistakes, particularly when we utilize them as resources for further reflection and modifications of our plans.

c. Cognitivist theory as exemplified in D.M. Merrill’s First Principles of Instruction or in Sticht’s functional context theory may play a central role in helping students progressively master a series of essential learning tasks like learning about new work processes in one’s job, starting a business, developing a week’s worth of healthy recipes for one’s family, mastering the fundamentals of basic algebra, or following and applying basic rules of English grammar and punctuation. Yet, as stated above, while near term knowledge acquisition may require well laid out mental maps in order to master a given set of tasks, longer-term knowledge development may require more subtle internalization in which one’s identity as a learner become positively reconstructed as part of the ongoing process of learning new tasks and procedures.

d. Behaviorist theory may play a principle role in developing the automaticity skills in increasing basic phonemic awareness or in mastering the fundamentals of basic arithmetic where practice through repetition is the more immediate key learning objective at hand. Even still cognitive development provides an important resource in helping students to internalize the schematic framework to make sense of what they are learning in order to enable such learning to flow into the long term memory. This often leads in turn, to viewing oneself as a competent learner (constructivism) which serves an important reinforcing and legitimizing role that is essential for persistence in learning, particularly when the challenges are difficult, yet potentially in reach (Bandura).

e. Pragmatic learning theory can be central in learning challenges emerging out of some gap in felt experience in which the pivotal challenge is to progressively overcome the gap through forms of knowledge and reconstruction of the context in which the problem was situated. Loss of a job could be one such source as could encountering a radically new and uncomfortable experience like incarceration or release from prison. Constructivist precepts could help in the firming up of a revitalized identity in lending meaning and purpose to the challenging work of activating needed sequential mastery in learning some complex set of tasks required to meet the challenges of coping effectively with a new work or social environment.

f. Even still, the more fundamental challenge may be that of appropriate problem identification and progressive problem solving to which a pragmatic inquiry-mode as exemplified in Dewey’s theory of learning could open up.

5. The insights gleaned on learning theory need to be incorporated into a broader set of insights and resources drawn upon in the challenging work of developing a teacher designed curriculum focus for a given course or program. We’ve seen such interfaces in our discussions of adult education theory and in the formal literature on curriculum theory in which Bruner’s spiral model and Dirkx & Prenger’s theme-based approach are prime examples of constructivist learning theory. As we shift this upcoming week into the topic of discerning the contexts of adult education theory we’ll see additional convergences between constructivism and the notion of literacy practices as detailed in Fingeret and Drennon’s Literacy for Life: Adult Learners, New Practices http://www.amazon.com/Literacy-Life-Learners-Practices-Language/dp/0807736589. We’ll also see the connection in Sticht’s Functional Context Education which shares strong affinities with Merrill’s ID2 integration of constructivism within a complex cognitivist design.

As we move through the remainder of this course we’ll identify various interfaces between learning theory and pedagogical strategies in Weeks 9 and 10. We’ll also give consideration to the strong correlations between CASAS and Merrill and Sticht’s complex view on cognitional learning theory and the pivotal role of constructivism on EFF, yet one that incorporates significant cognitivist components. Though we will not address it in this class, the issue of the relationship between qualitative and quantitative modes of student assessment and program evaluation are very much linked to divergent views on learning theory.

6. In drawing some closing conclusions, there is much to draw on from learning theory as indicated in the many discussions we have which we have had during the past three weeks. Among other things this includes the emphasis on constructivism in adult education and gaining a better sense of its many applications as well as coming to terms with the many contexts where its utilization may be limited or even counterproductive. What also stands out is the significant work of Merrill on the second level application of instructional design (ID2) and Sticht on functional context theory, both of which seek to establish linkages between cognitivist and constructivist theories and design principles from a highly nuanced cognitivist perspective. In the process of sifting through the ID2 perspective characteristic of both Merrill and Sticht, we’ve gained a better sense of the differences as well as similarities between their viewpoint and Dirkx & Prenger’s more constructivist-oriented theme-based perspective.

What is eminently clear is that a fundamental dividing point is not over the importance of content or theme-based instruction, which Merrill and Sticht fully share with Dirkx & Prenger, as well as the other constructivist learning theorists that we have studied. The primary difference, rather, has to do with the ways in which learning and supportive teaching takes place and the ways in which emergence and pre-planning interface. While we did not give as much attention to Dewey’s pragmatic theory of learning as progressive problem solving as I would have liked, his work too, as exemplified in Democracy and Education opens some intriguing insights for fresh learning that can be gleaned through a close study of his work.

7. The challenge is to think like a practitioner-inquirer in which it is not theory in itself that is the most salient factor. Rather, it is cogent application through effective utilization of theoretical insight as a critical resource in moving our understanding and practice forward in ways that facilitate demonstrably better outcomes of a more or less enduring type within the learning and broader life projects of our students. I’ll close with a quote from with Chapter 11, “Experience and Thinking” in Democracy and Education.

An ounce of experience is better than a ton of theory simply because it is only in experience that any theory has vital and verifiable significance. An experience, a very humble experience, is capable of generating and carrying any amount of theory (or intellectual content), but a theory apart from an experience cannot be definitely grasped even as theory. It tends to become a mere verbal formula, a set of catchwords used to render thinking, or genuine theorizing, unnecessary and impossible. Because of our education we use words, thinking they are ideas, to dispose of questions, the disposal being in reality simply such an obscuring of perception as prevents us from seeing any longer the difficulty (p. 144). http://www.ilt.columbia.edu/publications/Projects/digitexts/dewey/d_e/chapter11.html

The work on learning theory has the potential of becoming increasingly viable to the extent that we are able to draw on insights discussed in the readings and among us, in applying some of what we’ve learned to our own contexts, in assessing its impact as it gets played out in our practice, and in making additional adjustments or modifications to our teaching as warranted. The value of the knowledge of learning theories for the discerning practitioner-inquirer is no more and also no less than that, in which “to ‘learn from experience’ is to make a backward and forward connection between what we do to things and what we enjoy and suffer from things in consequence. Under such conditions, doing becomes a trying; an experiment with the world to find out what it’s like; the undergoing becomes instruction—discovery of the connection of things” (p. 140). Through this we learn and in the process make changes in the challenging effort of creating, or at least contributing to the more desirable outcome; learning experiences for and with our students as satisfactory as possible.

It is this which Dewey refers to as “growth;” some reconstruction of the world—that small, but far from insignificant portion of it where we have some control, and where our actions and where our undergoings make a difference in our own lives and among those with whom we have some influence in our desire to build the good community through which we might define as the good school. In this effort, effective appropriation of learning theory has a humble but not insignificant role to play.

Constructivist Learning Theory

Overview of Constructivist Learning Theory & Implications for Instructional Design

In the introduction to a book that merits much reflection, Constructivism and the Technology of Instruction (Ed.) Thomas M. Duffy & David H. Jonassen, the authors argue that both “objectivism” and constructivism accept the fact that there is a real world that in some way can be and is experienced.” However, from the constructivist perspective,

Meaning is imposed on the world by us, rather than existing in the world independently of us. [Consequently,] there are many ways to structure the world, and there are many meanings and perspectives for any event or concept. Thus there is not a correct meaning that we are striving for (p. 3)

As further developed in Bednar et al, in “Theory into Practice: How Do We Link,” argues similarly that since all we can come to know is how various human actors construct the world through “internal representation,” “conceptual growth,” in turn, “comes from the sharing of multiple perspectives and the simultaneous changing of our internal representations in response to those perspectives as well as through cumulative experiences.” Clearly, from this point of view, growth in learning is both possible and desirable through increasingly rich internal representations that provide enhanced efficacy in interacting with the culture and social environment from which and to whom the “individual” has been shaped.

The contrast is with the objectivist tradition, in which, in language of Bednar et al, “Objectivity is a goal we must constantly strive for.” As argued by Duffy & Jonassen,

"Objectivism holds that the world is completely and correctly structured in terms of entities, properties, and relations. [Personal] experience plays an insignificant role in the structuring of the world; meaning is something that exists in the world quite aside from experience. Hence, the goal of understanding [and therefore, education] is to come to know the entities, attributes, and relations that exist. The objectivist view acknowledges that people have different understandings based on different experiences….However, the impact of prior experience and human interpretation is seen as leading to partial understandings and biased understandings. The goal is to strive for the complete and correct understanding" [in which truth, however beyond the capacity for flawed and finite minds to fully attain, is a regulative ideal that should inform research, theory construction, and evidence based practice] (pp. 2-3)

As articulated by Duffy & Jonassen as well as by Bednar et al, the contrast couldn’t be sharper. As we saw in the previous lecture, there is a sort of great divide in learning theory in which constructivists link education to the pursuit of enhanced and meaning through an exploration of the rich chords of context including the dialectic between personal and collective perception in which self and social context are subtly interwoven rather than sharply separated as two distinctive entities. We saw as well that cognitivist learning theorists, like behaviorists posit an external world which has its own power and legitimacy that operates largely outside the parameters of individual perceptions. This is the case, cognitivists argue, even as they give greater credence to enhancing self-awareness through various information processing strategies that depend very much on personal perception. Moreover, as reflected Merrill’s essay, “Constructivism and Instructional Design,” some cognitivists, Sticht included, seek to build bridges with constructivist learning theory even as their predominant inclinations, in my view remain ultimately cognitivist in scope, an assessment of which I am not sure Merrill or Sticht would accept.

A few notations on Bednar et al.’s “Theory into Practice: How Do We Link?” (http://uow.ico5.janison.com/ed/subjects/edgi913/edgi913/istrategies/bednar(1995).htm),
will help to sharpen the discussion of the critical assumptions that underscore constructivist learning theory, including its contrast with what the authors refer to as the Objectivist perspective. The critical need, according to the authors, is to view the prevailing eclectic approach in instructional design with considerable skepticism in which “concepts and strategies [of learning] are abstracted out of their theoretical framework” simply because they seem useful in a given context. The authors maintain that cognitivist learning theorists, who share an affinity for “objectivism” with behaviorists, are, in fact, drawing implicitly on a broad range of behaviorist and cognitivist resources which cumulatively reinforce the objectivist paradigm. On this they point out the emphasis on “behavioral learning theory, cybernetics, and information-processing theory.

Whether or not this represents an adequate view of cognitivism is a point of contention to be explored throughout this lecture and throughout our two week focus on learning theories. For example, the distinctions get a bit fuzzier when considering “systems thinking,” which also falls within the purview of the cognitivist mix. Yet, in its emphasis on working toward holistic solutions could veer toward a more constructivist sensibility. The following links provide a brief overview of systems thinking:
• http://www.thinking.net/Systems_Thinking/OverviewSTarticle.pdf
• http://www.thinking.net/Cognition/cognition.html#Anchor-15951
• http://www.thinking.net/Cognition/cognition.html#Anchor-Reading-46848

Management theorist Peter Senge’s widely read book, The Fifth Discipline: The Art and Practice of the Learning Organization is a good example of a text that is deeply grounded in a systems-thinking design that appeals to cognitivist and constructivist-oriented management consultants and practitioners. Despite this complexity, I would agree with the intent of Bednar et al’s argument that underlying presuppositions (whether cognitivist or constructivist) play a powerful role in shaping how any resource will be utilized, and therefore, the ultimate orientation of a particular educational direction. In pushing their argument, Bednar et. al contend that:

Instructional design and development must be based upon some theory of learning and/or cognition; effective design is possible only if the developer has developed reflexive awareness of the theoretical basis underlying the design (italics in original).

Whether or not this is the case, a good number of those working from what might be dubbed “the constructivist revolution” in learning theory, argue this is the case. For these advocates this represents a profound paradigm shift of the first order magnitude. Whether or not insight from various learning theories can be fused in giving shape to a coherent instructional design and corresponding classroom practice, merits close investigation in its own right; a topic I will revisit when I get to M.D. Merrill’s research. For the immediate purposes here of fleshing out the basic assumptions of constructivist learning theory, the following comparative chart extracted from “Theory into Practice,” may be of more value.

Objectivist/Constructivist Contrasts:
Note: Bednar et. al represent the objectivist perspective through cogntivist rather than behaviorist learning theory in which the two are somewhat conflated.

Objectivist Learning Theory

Analysis of Content

• A tendency to simplify, and regularize, or systematize the components to be learned.
• Content components identified and classified based on nature of the content and goals of the learners.
• Component analysis presupposes and pre-specifies perquisite learning.

Analysis of Learners

• The focus of instruction is meeting the needs of the average or general learner
• The learner has a learning deficiency of some type which requires pinpointed remediation
• Pre-test assessment provides an important diagnosis of student learning needs
• The purpose of instruction is to help students gain efficient mastery of the information presented through various mind storage and retrieval processes.

Specification of Objectives

• The focus of instruction is the specification of the intended outcome, such as accurately filling out a job application
• Learning objectives are broken down into specific tasks and then organized into broader synthetic units in which each component builds into and builds up into a unitary block of knowledge.
• Instruction is to be based on performance objectives which are internal to each field of study or body of content.

Constructivist Learning Theory

Analysis of Content

• The content cannot be pre-specified since the learner must construct a frame of reference for even determining what content is relevant.
• A provisional topic range may be specified Still, getting to the relevant contexts that give shape to what emerges as the content to be explored requires a reflective discovery process in its own right.
• Most important is fresh data, fresh insights, fresh content that only emerges in and through the learning process itself.
• Units of information cannot be isolated from the contexts in which they are embedded, and therefore, the boundaries of what may are relevant are more permeable than traditionally viewed.
• There may be a need to simplify content for a novice learner, which needs to remain grounded in authentic contexts.

Analysis of Learners

• The focus of instruction is to enhance student reflexivity rather than that of remembering.
• Accordingly, the focus is on knowledge construction, the stimulation of the imagination, probing inquiry, and the exploration of alternative perspectives.

Specification of Objectives

• The focus of instruction is to enhance student reflexivity rather than that of remembering.
• Accordingly, the focus is on knowledge construction, the stimulation of the imagination, probing inquiry, and the exploration of alternative perspectives.

Concluding Thoughts

The remainder of the article further fleshes out some of the key assumptions that underlie constructivist learning theory such as the following:

• Students are not asked simply to solve pre-fabricated and artificial problems and projects. Rather, the learning challenge is to work with them to discover problems and create projects designed to either resolve them or probe more deeply into them that capture a larger context in which any given set of problems may be deemed as relevant. Learning objectives emerge accordingly as part of the discovery process.
• It is critical, therefore, to maintain the complexity of any authentic learning environment and situate learning within that complexity as students engage their roles within its highly contextual framework.
• High level modeling, extensive opportunities for role play and practice, and stimulating collaborative learning environments are key features of a constructivist learning/teaching design.
• These features, in turn draw out the necessity of multiple perspectives in which a significant learning challenge is to grasp and evaluate the different points of view. The objective in such a learning environment is obviously not that of extrapolating the one best answer, but for an enhancement of internal representations through deep reflection and empathetic, though critical dialogue and engagement.
• Evaluation, in turn, is less mastery of basic facts or isolated information than an assessment of the quality of thinking that the learner has undergone through inquiry-based education. Critical features include problem solving capacity, reasoned thinking, including deep contextual probing, and capacity to defend a point of view within some type of real-world-based perspective. Portfolio assessment has served as an important tool in providing an organized structure for a constructivist evaluation even as it by necessity requires some simplification of the context in order to manage.

Bednar et al. leave us with a few salient questions to ponder, namely:

1. Is critical thinking the goal of all learning?
2. Do the contexts in which the learning is to be applied relate to the nature of the learning experience? Stated somewhat differently, is there a direct correlation between learning and context mastery of a given topic?
3. Are there contexts where it is appropriate to apply traditional instructional developmental models and others where it is not?
4. Is it useful to distinguish learning capacities of novice from more experienced learners?

The authors leave these questions open. Nonetheless, one might draw a plausible inference that the reality may not be as clear cut from a pure assessment of their theoretical interpretation of constructivist learning theory. If that is, in fact the case then where does that leave their core argument that all aspects of developing a learning environment need to be based on a coherent (and seemingly singular) philosophical premise? I’ll let their minimalist prescription stand as the final word: “Minimally, we must be aware of the epistemological underpinnings of our instructional design and we must be aware of the consequences of that epistemology on our goals for instruction, our design on instruction, and on the very process of design.” This, indeed, may be a good starting point for an ongoing exploration of the cogency and relevant applications of an array of learning theories as they apply or might apply to adult education.
