Note that a graphing calculator is

**NOT** required but is especially helpful

in this class. I will be using a

TI-84 C (color) in my mini-movies.

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
jolene@jolenemorris.com 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
sections.

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.
