I have been working with beginning Algebra students for a good many years now. In that time, I have found myself answering many similar questions where students often tell me that when they are alone they get stuck and do not know where to look for help. This is certainly the case when problems are posed out of sectional context. After some interaction, it becomes clear that folks simply do not have the algebraic vocabulary needed when searching the index or internet for help and quickly become overwhelmed.
"I do not know what to type in when searching for help!"
To help, my idea was to create a
visually searchable database of commonly asked algebra questions. This compendium of algebra videos is intended to be more of a "how to" type of approach serving students looking to solve a particular problem in a short amount of time. More instructional or "lecture" type of videos are valuable and quite abundant. For these I would like to recommend James Sousa's
MathIsPower4u website.
After authoring two online
algebra textbooks published by
Flatworld Knowledge, I created a similar visually searchable list of videos for all of the "
Thy this!" problems found in the textbook.
This approach is not the silver bullet for success in Algebra, however, it does review well is appreciated by students who are more inclined toward a visual learning style. Everything on the
openAlgebra.com site is offered free of charge and is openly licensed with a creative commons license. This means that you are free to and encouraged to link to it, copy-and-paste into your CMS, build upon, improve and share the material.

I'm feeling good about our new free Trigonometry website. It's just a Blogger site, but it's getting good reviews. Today I added some big mobile friendly buttons.
This semester I ran a partially flipped open source Trigonometry course using a free textbook and youTube videos. To give back to the OER community, I have recreated my blackboard shell here in a single blog post. I am offering all of the worksheets that I have created below in PDF and source DOCX format under a creative commons license (cc-by-sa). Please feel free to copy anything here, modify, and/or redistribute.
Here I'm testing a web app using what I learned in Dart flight school. I built the app and then uploaded the build folder to Google docs... embedded below in an iframe. Very easy using angular dart. Some LaTeX to try follows:
