Unit IV: CBL/CBR & CFT



1.     What are key similarities or striking differences between the theories/models in a given unit? Do the theories/models in a unit share any common foundations or principles?
CBL or case-based learning includes the tenets of goal-based scenarios, anchored instruction, cognitive flexibility and case based reasoning (Oliver). CBL also uses real stories and historical context used mostly in decision making for role playing. This is also similar to cognitive flexibility theory in terms of using case studies or case comparisons for learning content. However, cognitive flexibility theory differs in terms of aiming to help students transfer knowledge and skills beyond the initial context. Cognitive flexibility theory (CFT) also works much in the same way as constructivism by building on what is already known.


2.     What are your initial reactions to these learning theories/models? What are barriers to their use? What benefits might be expected for those who overcome the barriers?
While both learning models require comprehensive databases of information, case-based learning seems to be the lesser of the two in terms of complexity. Because case-based learning primarily focuses on contextual application, the need to find cases for cross context application is absent. This may make case-based learning easier but does not negate the importance of finding quality resources that follow the 4 instructional architectures of learning objects for CBL/CBR/CFT: receptive, directive, guided discovery, and exploratory (Oliver). If this can be overcome, than the use of stories as natural formalisms for storing and describing memories and experiential knowledge (Jonassen, 2002) can be achieved as a benefit. The more multimedia the more time intensive as evident in "creating multimedia case study was significantly more labor-intensive than traditional case studies" (Jarz, 1997). If the time and support are available to invest in this type of approach, careful consideration must be placed in content and pedagogy for effectiveness.


3.     Would you attempt to use any of these theories/models with the students you are currently teaching or hope to teach in the future? Why or why not? Could elements of the theories/models be modified so that they would work with your current/future students?
Much work is to be done in terms of determining the educational efficacy of multimedia hypertext (Jonassen, 1992). In light of endless instructional technologies emerging in the use of multiple subjects, equal emphasis should be put on publishing the pedagogical importance of each application for the benefit of promoting the practicality and significance of IT. Cross examining the roles of different learning theories with different tools to produce the highest learning should be more readily available for evaluation. Everyone is interested in using different models and tools, but knowing how to best put everything together in a pedagogically sound, cohesive, instructional design is ever so challenging, especially at the rate in which this new frontier of instructional design continues to grow.

Case-based learning/reasoning and Cognitive Flexibility Theory both heavily rely on case comparison. These case comparison learning objects/materials would need to be sourced to established, reliable resources such as digital libraries. If these types of shared exchanges were available through some sort of partnership, the likeliness of using the two theories would certainly be feasible.


4.     Since we're taking learning theories/models that were not necessarily created with the Web in mind and turning them into Web modules, what Web-based tools or resources could be leveraged to carry out these learning theories/models online? Please spend some time identifying tools and resources for this last point, as this background research should help you complete your projects more efficiently.

  1. You mention that case based learning is not as complex as the cognitive flex model. I didn't really notice this when I first studied the lessons, but now I see your point. I think that case based learning is easier to design (from an instructors point). It may also be easier for students to execute.
