UNIVERSITY OF UTAH The Situated Application of Learning A Summary of Learning Theorists and Their Influence Rose Defa 12/7/2011 IDET 6431, Fall 2011 1|Page The Situated Application of Learning Situated learning through anchored instruction as a means of effective knowledge acquisition (P.Driscoll, 1994) is evident in various and evolved forms throughout much of instructional design literature. This paper will trace the theories that present related concepts and specifically how problem-based instruction can lead to students better able to develop the mental structures most useful in transfer of knowledge. An analogous theme will review the impact on instructional settings in general. Anchored instruction was introduced in 1990 by the Cognition and Technology Group at Vanderbilt (CTGV) as a means to facilitate situated learning. (Driscoll, 1994, p. 177) The focus at that time was the use of "video-based anchors as 'macrocontexts' for teaching and learning." (Cognition and Technology Group at Vanderbilt, 1993, p. 53) The videos were designed using stories rather than lectures. The stories portrayed realistic situations that simulate contextualized learning. The concept of context-based learning had emerged even earlier. The Collins-Stevens theory, Inquiry Teaching (1983), which explores effective teaching techniques for discovery learning, outlines a framework of 1) the goals and subgoals of teachers, 2) the strategies used to realize different goals and subgoals, and 3) the control structure for selecting and pursuing different goals and subgoals. (p. 251) Here is where we start to see similarity with situated learning – teachers pursuing goals where strategies include selecting cases, principles and theories (causal structure) that demonstrate the real world of the learner. The goal of Inquiry Teaching is to teach a general rule or theory and how to derive a general rule or theory. Collins and Stevens identified 10 teaching strategies and their application in multiple domains and they elaborated on the importance of using appropriate strategies to select the cases. Causal structure may not be useful in all types of content, such as teaching facts, but if the strategies (selecting positive and negative exemplars, selecting counter examples, generating hypothetical cases, etc.) are constructed as an inquiry approach to discovery they can accomplish the high-level learning desired. Overall, Collins believed students using high-level processsing Page | 1 2|Page skills such as forming hypotheses learn to construct new rules and theories by dealing with specific cases and applying new knowledge to new cases – turning learning into problem solving. (p. 276) During the same time period David Merrill's Cognitive Display Theory (CDT) (Merrill, 1983) proposed a set of prescriptions for achieving outcomes within a learning goal. His narrow approach, which does not attempt to integrate instructional design knowledge, (although he has drawn, most notably for this paper, on Bruner) focuses on which model to use considering two dimensions: type of content and desired level of performance (p 281). Merrill's performancecontent classification system, three levels of performance and four types of content, form the basis for objectives or test items. One of the most useful outcomes of the CDT theory is the Specifications of Objectives chart (p.292) which calls out input and output for assessing performance. CDT contributes the most to problem-based learning in consideration of learner control. For example, through the selection by the learner of relevant, contextualized examples, practice items and elaboration, Merrill hypothesized that conscious cognitive processing could facilitate learning. CDT, by its very nature, is embedded and system controlled, but student controlled options allow for redefining the instruction so that the student can search for internal or external resources to elaborate on the instruction - enhancing the development of learning strategies (especially for ill-structured learning environments) and problem-solving. Overall, Merrill recommends CDT as most appropriate for self-paced materials and instruction that uses an instructional management system, both which facilitate situated and problem-solving instruction. Again, during this time, Elaboration Theory emerged with a set of relationships to integrate knowledge and instructional design. Ruegeluth & Stein (1983) built on Bruner to develop the concepts of simple to complex, epitomizing, and prescriptive theoretical structures to scaffold upper level learning. Elaboration moves a learner from understanding the basic characteristices of an epitome to organizing and mastering the application. The use of analogy or situations and anchoring helps the learner move from familar ideas to new knowledge. This type of learning allows learner control through simple to complex sequencing and clearly labeled and separate instructional components. For example, an epitome lesson would present Page | 2 3|Page the learning prerequisites through motivational strategy, analogy or the organization of content ideas and then synthesize those ideas through elaboration and scaffolding. Ideas and learning are supported through creating relevant situations and opportunities to reconstruct knowledge in new situations - situational problem-solving. Cognitive flexibilty, developed by Spiro, et al, (1992), focused on applying knowledge to new applications (p. 59) especially in ill-structured domains. But to do so, Spiro was clear that learners need to represent knowledge from different conceptual and case perspectives. Learners reassemble pre-exising knowledge to fit the new situation. He purported that that flexible learning environments, non-linear learning and the computer were all ideal medium for the reassembly of pre-exising knowledge to fit a new situation. According to Spiro, "All domains which involve the application of knowledge to unconstrained naturally ocurring situations (cases) are substantially ill-structured." (p. 61) The mastery of complexity and transfer are possible when students reach more advanced treatments of subject matter. Facilitating this requires that the instruction go beyond simply retrieving knowledge from memory in a learning situation to the ability to flexibly reconstruct background information relevant to the situation. Spiro presents as one solution structuring hypertext learning environments where multiple exposures through multiple contexts support transfer of problem solving. (p. 71) Cognitive load theory became pivotal to understanding the differences between novices and experts where the mastery of more complex information requires effective problem-solving abilities. Sweller (1988) determined that "domain-specific knowledge in the form of schemas, is the major factor in distinguishing experts from novices in problem-solving skill." (p. 258) He suggests that the traditional method of practicing on many problems is an inefficient way to gain problem-solving skill because the learner uses limited working memory to focus on attaining the goal rather than on gaining the schema of how the problem is structured – a necessary acquisition for knowledge transfer and building related advanced knowledge structures. Sweller and Chandler (1991) continued to study the relationship between learning and problem solving. Experiments during the late 1970s and the 1980s indicated that in some cases, learning and problem solving were incompatible, particularly in that means-end processing of problems Page | 3 4|Page did not result in learning the structure of problems. Schema and cognitive load theory began to be used extensively not only to explore the differences in problem-solving skill between novices and experts, (p. 352) but to analyse the effects of different types of instructional designs. Cognitive load theory generated many experiments demonstrating the effects of goal-free problems, worked examples, split-attention and redundancy on instructional effectiveness and most importantly, learning. These effects and the implications for learning encourages instructional designers to reduce cognitive load. Sweller (1994) analyzed intrinsic and extraneous load as an explanation for difficulty in mastering information. They explored the natural origins of difficulty (the level of difficulty of the material itself); artificial difficulty (which can be alleviated by instructional management) and procedures to reduce difficulty. They found that cognitive load effects can be useful in determining instructional designs that contribute to learning efficiency. Since most knowledge is encapsulated in schemas which reduce the amount of working memory needed during learning, careful attention to intrinsic and extraneous load can substantially enhance efficient learning, particularly in high level learning, by reducing the number of interacting elements with which the working memory must deal, and avoiding split-attention and redundancy effect. Later, Sweller, et al (1998) demonstrated that appropriate instructional design (goal-free problems, particularly in math and science, worked examples, completion problems) can be effective where problem-solving performance is critical. Most recently, Schrymer and Spiro (2009) suggested revisiting cognitive load theory and learning goals in ill-structured domains, especially to acquire flexible knowledge. (p136) Their work examined learning via the Web as the "quintessential multimedia environment for complex learning, particularly in ill-structured domains." (p134) However, learners in this environment "must be prepared for discovery, complexity, change and creativity." I would suggest that the Web may be the ultimate situated learning - where learners explore connections, comparisons and contrasts in new contexts and through comparing multiple examples of situational information. (p. 137) The authors discuss the implications of cognitive load including the effects of affordance, motivation, and redefining germane cognitive load in ill- Page | 4 5|Page structured domains, concluding that "web learning (in ill-structured domains) holds great promise" (p. 148) for freeing resources for knowledge acquisition. Cognitive load cannot always be avoided; in fact, oversimplification or neglecting in-depth materials can interfere with building the schemas required for later acquisition of complexity. While well-structured domains are easily suited to construction and automation of schemas, illstructured knowledge relies on germane cognitive load to build interconnections. Many of the techniques for creating sophisticated schemas are natural to a web-based instruction, "crisscrossing knowledge landscapes, experiencing multiple perspectives, patterns of context dependency, identifying how surprising similarities and surprising differences unfold." (p142) The research is still undefined on the benefits of deep learning on the Web, but I would argue that the technological revolutions (particularly now Web 2.0) allow for dramatically increased flexibility in situating, anchoring and contextualizing learning to create the instruction that minimizes extraneous cognitive load while maximizing the creation of schemas for advanced knowledge through application of germane information. Most simply put, the situated, anchored, problem-based value is that humans have constraints to information; they learn by manipulating relevant information and creating new structures to apply that information. Instruction that facilitates developing rich schemas in long-term memory, efficiently retrieving relevant information into working memory (matched to the learner's abilities and context) will result in the desired spiral of learning.
