I think the biggest consideration we have to take into account when designing these computer-based instructions, is the idea of inflexibility. What do I mean? When we teach a normal lesson, we can easily adjust it to match what is going on. We can move faster, move slower, add content, delete content, question for understanding, etc. In these computer-based instructions however, we cannot.
So that means we must plan, and plan very well. We have to take into consideration the vary levels of our students, of our given audience. We have to provide more than we would normally think is necessary in order to prepare for the unexpected.
Of course, these Computer-based instructions provide many unique advantages too. They give students freedom to choose their pace. They can provide interactivity, instant feedback, and individually tailored lessons. But... all of this means more planning on our side, on the design side.
Webquests like this one about Composers and Time periods, are a good example. I chose this one because overall it provides a good introductory activity into classical composers/time periods. It's also nice because it is relatively short in regards to demands and has a slight whimsical feel to it.
Here is one that can be incorporated into our concert/performing ensembles. The design isn't the greatest, but the idea of having students formulate their own concert program is a powerful activity and can sometimes yield great results. If not, then at least they gain some insight into how difficult a process it can be for us.
The last one I'll share for today is about selecting orchestral instruments. The idea being you have to help your friend figure out what they are going to play next year when they join orchestra. Again some design issues. But it does have a great list of resources and also some links to some really cool interactive activities.
