Bear in mind, paulc, is that much as I would like that these courses actually be accredited at this stage it is unlikely to happen and we will have to settle for the derived benefits to only be informally educational. Having said that, however, once we begin this process and can demonstrate that we can run courses online in a consistent manner that meets with requirements for accreditation of some sort then it brings us one (or more) steps closer to making the Immortality Institute a recognised educational institute.
While it is true that at the beginning we can provide this course at no credit on a volunteer basis it is also a very important way of testing our own program and methods.
I suggest that more interim evaluative means are required and also a rigid text outline that will require an associated text(s) of some sort. By incorporating a recognized text, existing curriculum requirements for targeted or specific subject material and approved testing guidelines we also improve our chances of gaining accreditation. We don't really have to reinvent the wheel to provide the kinds of basic courses we are discussing.
Once we have established the full course outline we can also take this to the Carnegie or other philanthropic organization that is funding education development as an outreach program to improve accessibility to education in poorer parts of the world. We could use the course as the central theme of a grant application and ourselves as the basic staff to run the program.
MIT happens to be offering free online courses now and there are others. You cannot receive credit from the open enrollment auditing structure unless you are enrolled at MIT I believe but you can participate and actually attend the course.
We would need to develop validation criteria for our tests and methods. Essays are good but also require grading scales so that the criteria are clear and objective. This is different than a traditional classroom environment as there might be various times of the day when teacher and/or assistant teachers (TA) are present online but certain times deadlines for giving assignments and submitting homework, taking exams and answering student needs must also be clear cut. I recommend using online video lectures that allow us to circumvent the copyright of using other peoples prepared video.
We can however use any open source material we deem appropriate from PLoS or Library of Congress, or any numerous sites that might give us permission. Keeping the first course simply is also important so it is easier for us to learn from the process and refine our technique quickly. TO do this we must be prepared to follow up on our students and determine how well our presentation prepares them for other programs later.
We might also develop a licensed relationship with an advanced textbook publisher to use their online resources if we are also asking our students to use the associated textbooks. However that kind of relationship needs to be formalized for our protection.
