Toward a rhetorical theory of deixis

This article advances a rhetorical theory of deixis, a theoretical and methodological orientation that infuses the linguistic concept of deixis with rhetorical understandings of ethos, place, and time. Deixis reveals the rhetorical dynamics within the fabric of spoken discourse, dynamics that often refer to what is outside the text to make sense of what is within it. Ultimately, I argue that identifying the deictic indicators within a speech text enables the critic to pinpoint where, how, and why a speaker activates the physical elements of the speech situation as a material means of persuasion. After outlining the theoretical tenets of this approach, I analyze Harry S. Truman's Address to the National Association for the Advancement of Colored People on June 29, 1947, to show how a rhetorical theory of deixis orients the critic to the bodies, places, and temporalities implied in and displayed through speech.     

Toward a cognitive schemata theory of self-instruction

An initial outline of a cognitive schemata theory of self-instruction is presented. Three levels of schemata are described briefly. Attention then is devoted to the cognitive organization and operation of these schemata in relation to procedural and declarative knowledge stores, and in relation to everchanging situational information. The primary objective is to provide an initial basis for conceptualizing the cognitive competence required for self-instruction.Requests for reprints should be directed to Jack Martin, Associate Professor, at the above address. Work on this paper was begun while the author was an Associate Professor in the Faculty of Education at Simon Fraser University.     

Toward a design theory of problem solving

Problem solving is generally regarded as the most important cognitive activity in everyday and professional contexts. Most people are required to and rewarded for solving problems. However, learning to solve problems is too seldom required in formal educational settings, in part, because our understanding of its processes is limited. Instructional-design research and theory has devoted too little attention to the study of problem-solving processes. In this article, I describe differences among problems in terms of their structuredness, domain specificity (abstractness), and complexity. Then, I briefly describe a variety of individual differences (factors internal to the problem solver) that affect problem solving. Finally, I articulate a typology of problems, each type of which engages different cognitive, affective, and conative processes and therefore necessitates different instructional support. The purpose of this paper is to propose a metatheory of problem solving in order to initiate dialogue and research rather than offering a definitive answer regarding its processes. This paper represents an effort to introduce issues and concerns related to problem solving to the instructional design community. I do not presume that the community is ignorant of problem solving or its literature, only that too little effort has been expended by the field in articulating design models for problem solving. There are many reasons for that state of affairs. The curse of any introductory paper is the lack of depth in the treatment of these issues. To explicate each of the issues raised in this paper would require a book (which is forthcoming), which makes it unpublishable in a journal. My purpose here is to introduce these issues in order to stimulate discussion, research, and development of problem-solving instruction that will help us to articulate better design models.     

Towards a theory of instruction in the 1980s

The purpose of this article is to provide a historical perspective on the contributions of learning and instruction to instructional theory and to discuss some of the major obstacles currently inhibiting the growth of “Instructional Theory.” Some suggestions for future development of this discipline are provided. In clarifying the impediments to instructional theories' development, heavy reliance is placed upon the process of theory construction as perceived by philosophers of the natural and social sciences. Some comments are made regarding the appropriate use of instructional theory in developing nations.     

An information processing approach to a theory of instruction

This paper is a version of the sixth ECTJ/ERIC-IR Young Scholar Paper, an annual award initiated to stimulate writing by young professionals in the field of instructional technology. Preparation of the paper was supported by the ERIC Clearinghouse on Information Resources at Syracuse, NY 13210.     

On a theory of instruction: Why different forms of instruction result in similar knowledge

Why can instructional processes having widely different topographies—such as teaching through a demonstration (modeling), teaching through verbal explanation, and teaching by simply providing an occasion for the child's direct contingent experience—all result in the development of the same or similar knowledge? A recent series of experiments that examined the role of instruction in the intellectual development of young children provides evidence for the equivalence of different forms of instruction and leads to the postulation of a set of invariant processes of information exchange that underlies the surface characteristics of various forms of instruction.     

Movement Toward Interdisciplinary instruction: Teacher Educators Respond

Tracy completes her laboratory assignment and gathers her books as her second period science class draws to a close. As she leaves the room and heads to her next class, Tracy stops by her locker to drop off her science text and pick up an English literature book for third period. For her, the separation between science and English is both physical and mental. In the time it takes to move from one room to another, Tracy has also moved from one ‘mind set’ to another, exit science, enter English.     

Cognitive load theory and music instruction

In two experiments, the principles of cognitive load theory were applied to the design of alternatives to conventional music instruction hypothesised to facilitate learning. Experiment 1 demonstrated that spatial integration of visual text and musical notation, and dual‐modal delivery of auditory text and musical notation, were superior to the spatially separated placement of the same visual materials, demonstrating the split‐attention and modality effects respectively. In Experiment 2 there were four conditions differentiated by the presence or absence of musical notation and the simultaneous or successive presentation of auditory music, written explanations, and musical notation. Results indicated that the presence of music notation had no effects, but that the simultaneous presentation of either two or three information sources was superior to successive presentation. These results provide further empirical support for the need to consider cognitive load theory when designing instruction in any domain.

Cognitive efficiency: Toward a revised theory of media

Within and beyond the field of educational technology, Richard Clark's writings are widely believed to have shown that any number of media are equally capable of delivering any instruction, so that media choices are about cost and efficiency but not about cognition and learning (Clark, 1983; 1994b). However, if it is accepted that one type of efficiency is cognitive efficiency, then it follows that media choices are often about cognition and learning and can profit from an understanding of cognitive processes. Media and learning can then be reconnected in limited ways that do not compromise any of Clark's main points, and doing this will bring media work into line with current research into the role of surface information codes.     

The twin-cycle experiential learning model: reconceptualising Kolb's theory

Experiential learning styles remain popular despite criticisms about their validity, usefulness, fragmentation and poor definitions and categorisation. After examining four prominent models and building on Bergsteiner, Avery, and Neumann's suggestion of a dual cycle, this paper proposes a twin-cycle experiential learning model to overcome identified problems and integrate the experiential learning field. In the model, an initial response to a learning stimulus or intent occurs at the intersection of a concrete/active/primary learning cycle and an abstract/passive/secondary cycle. The model accommodates four classes of variables that describe six broad learning activity types (engage in, write about, observe, hear/see, read, hear), the three senses these activities predominantly engage (kinaesthetic, visual, aural), six learning modes (concrete, active, primary, abstract, passive, secondary) and four learning stages. Importantly, instead of assigning learning modes to stages of learning as Kolb does, the model assigns them to the two cycles as a whole.     

The elaboration theory of instruction: A model for sequencing and synthesizing instruction

This paper describes a novel instructional model for sequencing, syntheizing, and summarizing subject-matter content. The importance of such models is discussed, along with the need for a significant change in the role of subject-matter structure in instruction. A zoom-lens analogy is presented to facilitate an understanding of the elaboration model of instruction. Some basic concepts and principles upon which the model is based are described. The basic unvarying components of the elaboration model are described. And finally, some variations in the model for different kinds of goals are described. The elaboration model follows a general-to-detailed pattern of sequencing, as opposed to the hierarchically based sequences derived from Gagné-type task analyses.Many of the ideas described in this paper were developed under two projeets, one funded by Brigham Young University in Provo, Utah, and the other by the Navy Personnel Research and Development Center in San Diego, California; however, the ideas expressed do not necessarily constitute the opinions of the funding institutions.     

Moving beyond Mozert: Toward a democratic theory of education

Most liberal political theorists of education argue that it is better to teach students to tolerate diversity, than to protect the potentially illiberal commitments of some members of the political communities. In fact, neither approach is wholly satisfying, yet they remain the focus of much political theorizing about education. This article suggests that this misguided focus is, in part, a consequence of a focus, by liberal political theorists of education, upon the 1987 Mozert v. Hawkins court case. Mozert raised serious questions about the nature of toleration in liberal society, but from an educational standpoint, the Mozert case led political theorists to consider what curricular content is appropriate for liberal political education, rather than on the practices that democratic citizens must cultivate. I turn to Hannah Arendt to offer a critical account of the liberal responses to Mozert and then call for a theory of democratic education that fosters practices of democratic decision-making and has, as its aim, not merely to foster respect for diversity, but to allow future citizens to practice critical engagement with diversity.     

Toward a theory of teaching: A social learning view

Two hypotheses were investigated: Do teachers spontaneously use modeling techniques during instruction, and are teachers who are trained to use these procedures more effective? Twenty-four teachers attempted to instruct a like number of 5-year-olds to seriate length. Twelve additional youngsters served as uninstructed controls. Untrained teachers made little use of modeling techniques and were generally ineffective. Trained teachers were significantly more effective than their untrained counterparts. Teacher use of specific modeling behaviors correlated with teaching success. The results were discussed from a Social Learning Theory view of teaching.
