As typically happens in these types of threads, I think we're starting to get lost in the symantics of the terminology. We're now getting into what each person thinks the definition of is (oops)...... I mean Structured is.
Does "structured" mean following a prescribed lesson plan, or does it mean determining what you are going to do next, on the fly?
The more experienced instructors will be able to start with a predetermined task/exercise, then, based on the results and feedback, determine where to go next. We might ask a low intermediate to make a slightly skidded/christie turn, then determine whether each student needs to work on edging, or balance or rotary skills, etc. We might determine that each student needs something different emphasized, but have a single exercise that all can perform to work on it. Or we might determine that each student should do something different, and run "parallel" lessons with some students doing different exercises than other students.
Is this considered structured or unstructured? In my personal definition, even though I have specific exercises I want the students to do, I'd consider it unstructured, only because it wasn't pre-planned. But I may continue with an existing lesson format (i.e. command/task or guided discovery), just swapping out the exercise or intended outcome based on the feedback and results. This happens a lot when one student picks up on one way of my delivering the info, but another student doesn't, and needs another way of achieving the desired outcome. I don't necessarily want to hit the first student with another method because they already "got it", so I may have them do something else while I get the other student to be able to get the desired result. You know... the best laid plans of mice and men....
Either way, there's always some sort of structure, and some parts of the lesson that are unstructured. Is this conversation is structured??? you click on "reply", you type a message, you hit "submit", you wait for someone else to reply (feedback). That's structure, right? But it's also unstructured because what you say next will change based on the feedback from the other posters. That's unstrcutured, right?
So my take on the ICSFM's original post/poll, was whether I follow a strict, structured lesson plan (the activities I ask the students to do), or whether I might change the plan based on the results/feedback from the students as the lesson progresses (unstructured)
