INSTRUCTOR TIP FROM JOLENE: Order of your solutions does not matter; however, MML will mark the answer wrong if you forget commas.
INSTRUCTOR TIP FROM JOLENE: Careful when entering your answer. Use the matrix template on the toolbar at the bottom of the screen to get the matrix square brackets. Do not type the square brackets from the keyboard. MML will mark your answer wrong if you type [ ] instead of using the matrix template.
I am in the process of adding closed captions to all my mini-movies, but since I have several thousand
mini-movies on my site, this will take quite some time. All pdf documents are available in their original Word format for those who need to read
the math equations with a screen reader. As I learn how to make my site more accessible, I will add these features. If you are a member of my
site and need accessibility, please contact me via e-mail at
firstname.lastname@example.org and we'll work out something until my site is fully accessible.
As I create new mini-movies, I have been including the closed captions and transcripts. But each day I go back and add closed captions and transcripts to at least one mini-movie. To understand the scope of this problem, I have over 5,000 mini-movies on my website. If I do only one mini-movie per day, this conversion will take over 13.5 years!! As such, I am working on highest priority mini-movies first, and I am looking for alternate ways to add captions and transcripts to existing mini-movies.
Closed captions are word-for-word translations of the mini-movie, while transcripts are "descriptive" transcripts to reflect not only the voice but the visual component of the video. Coming soon: A web page with non-graphical links to all descriptive transcripts for each course.
What are the mini-movies? The mini-movies are marked with a
icon. They are MP4 video files that contain a teaching
presentation with an audio track. These were recorded in my
office (not in a live lecture) so they are short, but very dense
with compact information. Movie
controls are available so you can replay, pause, and skip
At times, a mini-movie may stop abruptly in the middle of play or it might not load at all. The website bandwidth that I pay for only allows 3-4 movies downloaded at a time. So if your mini-movie stops in the middle or won't download properly, refresh/reload your browser window and it should work.
