under http://www.learnoutloud.com/ .
I tried out each of the above URLs. Of course the top one is the most direct, and the one you should use. The second URL takes you to a page of all the science courses (114 of them, as I recall). The number one course listed is the free astronomy course from Michigan Tech. The third URL takes you to the LearnOutLoud home page which gives links to a zillion other courses.
So, using the first URL above, I got to the correct page. Then I needed to scroll down to the list of lectures. Today there were four available (the first 4 lectures of the course). So far, I have watched only the first lecture which was an introduction. The lecture lasts (I'm guessing) about 45 minutes. But the first fourth or third of the lecture was instructions to his real class members about tests and so on. You could skip that part by sliding the progress button over to the right about an inch or so.
Some of my grandchildren could probably watch these lectures and learn a great deal, if they were in a teachable frame of mind and equipped with a healthy curiosity about astronomy. I wouldn't let the "college course" label dissuade any of them.
The only thing that he said that caused my eyebrows to go up was when he said The Very Large Array was in Arizona. He must have misspoken. The Very Large Array is in New Mexico. I am going to check his forum pages to see if anyone else caught that. I may just email him and point out his slip of the tongue.
Postscript: This morning (9-18-08) I emailed RJN, the professor, about his gaff. Here is his reply:

Subject: Re: VLA location
Thanks for your correction. Yes, indeed, the VLA is in New Mexico. I have even been there. Unfortunately, I can't correct the video. I can correct the PPT slide but that likely won't be used again for a number of years. - RJN
