This semester I posted mobile phone friendly solutions to exams in my Elementary Algebra and Intermediate Algebra courses.  Both are one-semester courses. This was easy to do using a basic snipping tool and Blogger.

In doing this, I was able to save some valuable class time. We are not quite finished, I still need to cover conic sections (chapter 8) in Intermediate Algebra, but students definitely said they appreciated this approach. Please feel free to comment or share.

App Inventor Tutorial

Here I have created a mathematical programming tutorial using the MIT App Inventor platform.

[ Algebra App: Evaluating a Linear Expression ]

The tutorial guides students through the process of making the following android application.

The almost completed program follows:

Please feel free to try it, distribute, and remix.  This is a "work in progress," so any suggestions would be greatly appreciated.

Over 100,000 Views!

My algebra YouTube videos broke the 100,000 view mark! I know it is not a lot compared to many others out there but it is a milestone for me nonetheless.

I have received a great many "thank you" type comments and emails. It still amazes me that I can help so many so easily.  And I am getting better at tagging and SEO so hopefully this run will continue to accelerate.
