I've been developing some modules/courses for secondary school science. For presenting content with resources, I've used both "File" and "Page" for the content. Right now my modules are mostly HTML pages that I uploaded (ie "File"), along with styling that fits nicely with the theme. The advantage of using "File" is that it allowed me to use a single stylesheet that controlled all of the different modules. However, the downside to this is that it is more troublesome to edit a module because the html file needs to be modified offline and then uploaded again.
I'm curious as to what other high school teachers do when adding resources? html pages, uploading files, rich text with minimal styling, etc.
An example of one of modules can be found at http://www.dryfly.ca/school/
Check out Mr. Smith's Physics 11, and maybe the Intro to Kinematics for an example.
Any input on what method of resource to move forward with is appreciated.
