I could see how this model could definitely be used effectively to prepare business students, lawyers, crime scene investigators, etc. because it presents students with a case in which they have to figure out a solution, or draw a conclusion. I think this model presents a great way for students to learn about realistic decision making. I think students could have some great collaborative discussion when using this model with small groups.
One barrier would probably be the time that it would take to design and develop this model. Teachers would have to create cases and provide students with resources to help them solve the cases, or provide hints. I think it would be helpful for teachers to work with other teachers in teams to create modules such as this one. Different teachers could be responsible for presenting different resources that go along with the case.
I would be willing to try out this model in the classroom. However, if I used it in the classroom, I would definitely put students in small groups so they would be able to collaborate with their peers and have discussions with their group members about the case. I think this model would be a great way to incorporate relevant contexts and real world situations and decisions.
If I used this model online, to present the case, I would probably use some type of video. I might create one on MovieMaker or iMovie. Also, I would incorporate a discussion thread or wiki where students could share their thoughts about the case with their classmates.
I also found the Case-Based Reasoning model effective for teaching students. I think it would be useful for students to retrieve past information that they have learned, and reuse it, revise it, and then retain it. It is useful for students to remember how they solved past cases, so they can apply their knowledge to future cases.
