The biggest job in things like Moodle and its courses is really categorisation and the best way to go about doing this. You often end up restructuring the whole menu system over and over as subjects and languages pop up, ans subcatagories seem to move from location to location. For example, the learning how to use Sugar courses I made are really for specific subjects like programming, usage, maintenance, etc. But I grouped them all under one subheading until there is enough material to warrant creating other sections. I would suggest doing something similar. That is to say, start off with subject sections that are quite broad and general so it looks like there is a significant amount of content available. And then slowly start changing the categories. In terms of the database you mention, I'm not sure if you mean using the database module that is included with moodle, just for subjects and the usage thereof. Is what you want a kind of launchpad for subjects? Either way the database module is extremely powerful, and can be used for almost anything to categorise and link its details to the content in the courses. If you do need help on creating or maintaining a database, let me know... kind Regards, David Van Assche. <div class="gmail_quote">On Sun, Sep 13, 2009 at 9:17 PM, Edward Cherlin <<a href="mailto:echerlin@gmail.com">echerlin@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I see that Moodle can support a MySQL database. Has anybody implemented a system with a database of learning modules that a teacher can select from in creating a course? If so, then we can design such a database for easy searching by various relevant criteria and for linking modules together in sequences that respect topic dependencies. Bryan Berry has suggested that we need something like 10,000 modules for every topic in every subject at every grade level in K-12. I am thinking of an architecture in which we could provide places for multiple versions of each topic module using different instructional methods keyed to different learning styles in different languages and cultures. For example, I might offer a lesson plan using Walter Bender's Turtle Art Portfolio functions and Alan Kay's Etoys/Smalltalk approach. You can get a bit of the flavor in my reworking of an Alan Kay lesson sequence on Galilean gravity at <a href="http://wiki.sugarlabs.org/go/File:Gravity.odt" target="_blank">http://wiki.sugarlabs.org/go/File:Gravity.odt</a> I intend to redo this again entirely in Turtle Art Portfolio soon, now that I have a lot more of the bits and pieces of my approach coming together. <div><div></div><div class="h5">-- Edward Mokurai (默雷/धर्ममेघशब्दगर्ज/دھرممیگھشبدگر ج) Cherlin Silent Thunder is my name, and Children are my nation.
