SIMILARITIES & DIFFERENCES
Interesting enough, I initially believed both Case-Based and Cog-Flex to be mostly similar in nature. The basic jist of the two being that they each rely on cases and situations from past circumstances as a means to teach, adapt, resolve, and move forward any type of problem encountered. However, as I read and listened and re-read the information, I came to understand that use of previous cases were but a portion of how the two models work; they now appear mostly different.
For instance, the biggest two differences I noted are that case-based is best design in a team setting because of how extensive and vast the design process is.The second is that case-based appears more structured than Cog-Flex. Where case-based simply employs a story or series of stories to be discussed and conclusions made, cog-flex is more ill-structured and designed to allow the student to come up with his or her own thought process, form a solution, then if need be (depending on the circumstance), review the same information and provide solutions from a different context. Basically, cog-flex is more "flexible" in allowing learners to process and reprocess information to solve an issue. As noted by Jonasson (2002), I agree that unlike a structured enviroment, having an issue with no rhyme or reason and or offers a great deal of tid bits that may or may not be related leads to a more open-ended, multiple-solution problem that may or may not have several underlying issues to go with it. To me, this is more "real world", especially in the field of medicine...which leads to my reactions.
REACTIONS
I very recently observed a dear uncle of mine deal with what he and his doctors initially thought was Lymphodema. All the visible signs were present and internally, when certain organs were tested to confirm this condition, the doctors found success; this 74 year old, non-smoker, that loved sweets had Lymphodema. Approximately 6 months into treatment, the methods of relieving his body of the fluid became unsuccessful. Another month in the hospital, a liver biopsy, and some extensive research and tests showed that is was not Lymphodema, but rather Amyloidosis--a rare blood disease. He had had the perfect storm of problems brewing in is system for months and it was just laying in wait. Unfortunately, the timeliness of the diagnosis was too late for him to recover. This situation, to me, is a good example of the difference between what could possibly be the effectiveness of the two learning models. I may be off in my thinking and a bit biased, however, I believe it applies. The bit of information the doctors had at the onset, I compared to the case-based model---small town doctor, given the symptoms, a few cases and some prior knowledge, the diagnosis was simple, Lymphodema. But wait, using the cog-flex model and examining all the many different pieces to the same puzzle over a two year period, coming up with new ideas, the making comparisons to see if there are connections in order to get possible solutions, I believe, would have been a more effective and timely model in getting an accurate diagnosis. as underlying symptoms presented themselves at different times for the duration of this year-long illness. This may be a stretch, but I believe my uncle's situation is a very good learning experience and a case to be studied using either model.
With that in mind, having been a believer in using the case-based model in past years, I now tend to lean more to cog-flex as it provides a means to be more open-minded and flexible in possibilities.
ANY BARRIERS?
As with any distance education technology or teaching model, there are sure to be barriers. For the case-based model, the largest possible barrier I note is resources. This includes the time, the people, the cases, and finances. As mentioned in our lectures, case-based learning is geared more for a team effort in getting the program developed due to the complexity and the vast amount of work that goes into designing a cased-based course. I see a great deal of time consumed in efforts to make the class as well-rounded as possible by including enough of the "right" cases to be able to draw from and discuss. With cog-flex, the same holds true but may be just a bit easier to assemble the sources of information from which students will draw thoughts and examine. Where I see case-based as needing to be somewhat complete in the sources participants will study, cog-flex only needs information that is related, but not necessarily complete--allowing students to make up their own conclusions from "implied" information. A person is not limited in the possibilities with cog-flex because of what can be "implied". As for the people and finances, the barrier may present itself by having limits on both; the manpower and manhours needed for development may not be there to allow design and implementation in a timely manner.
WHICH MODEL IS FOR ME
As mentioned previous, while I have not totally loved case-based work, it does offer the opportunity to alleviate all the ground work in solving current issues. In a sense, nothing is new. There is or could always be a situation where an event or illness or class where the circumstances were very similar, if not exact, can be adapted for modern times. I do believe case-based learning is an exceptional tool for students to see how history does indeed repeat itself and in doing so, it offers a means to learn from it, adapt it, and revise the solutions to lessen the impact and or prevent the issue from repeating itself yet again. Cog-Flex has, over the duration of this class, become my favorite for this unit. I'm glad I was allowed to actually participate as opposed to develop a cog-flex course. I did get a better idea of how to use the model and how it should be set up. From the student perspective, I believe it a better model than case-based because in many instances, I had to put two and two together as well as five and seven together to come up with solutions and predictions that were close to being equal to four and twelve. I surprizingly enjoyed having to analyse and compare the information for similarities.
TECHNOLOGIES
Due to the nature of case-based learning, I believe the technology used in creating the course can vary greatly. In general, I think, any learning software can be used. I have come to enjoy the simplicity of using Coursesites and the fact that it is free, however, the layout can at times be confusing. In this case, great care and diligence in laying out a case-based course will have to be taken to ensure to structure is sound, is not confusing, and participant can make for good discussion and learning. Personally, I would opt to build the class using a web site service such as Weebly For Education; an environment where I control the layout, design, and flow of the course. Cog-Flex, on the other hand is a great candidate for use with Coursesites. I base this on what I learned with the Plantations assignment. The varying types of media that can be linked to the main question for the study makes a way for easy access to all the content, cases, and discussion forums from a single application. In the event that interactivity is critical fkr thecourse, then Glogster is yet another technology I'd use. It allows varying media, tons of suitable templates, linking to other applications that can handle high amounts of content (a case database). Ultimately, there are numerous options for design; one last aspect to consider when selecting how to create a case-based or cog-flex learning environment is the subject matter and facilitator. I, for example, would have difficulty teaching a course of solely content and a few images. The software should be one that compliments the learning environment, the topic, and the facilitator as well (if feasible).
