I just connected the dots! I guess I got carried away in developing these activities for Casos I Semester. I really wasn't thinking about my students being in their first year. Now that I have stopped and thought about it, the activities are to complex for Caso 1. Each activity represents 3 casos.
Considering what I have read about Backwards Design, plus revising the Casos 1 from 2006, 2007 and 2008, I can say that these activites are too broad. I have started to read "Learning with cases". Cases are not the same as a subject. So, up to this point I have read and outlined Caso 1 Needs Analysis Report. I can say that I have a grip on the whole concept on how to build a case. I have a better vision now of what needs to be accomplished.
I would like to say that all this has given me a totally new perspective on teaching considering the fact that there are parallel activities for the learner as well as for the educator. Right now, I am learning how to build a case out of scratch. It's my creation but in order for it to be created I need to learn about it first. Which means that what I am learning is just for me, the goals, assessments, and activities need to be created in order for my students to crack the Caso. WOW!!!
