Visually Searchable Algebra Video Compendium


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.

[ Elementary Algebra (Algebra 1): Try This Videos ]
[ Intermediate Algebra (Algebra 2): Try this Videos ]

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.

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.


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.

Adopt One Open Textbook and Make a Difference


The passage of the Open Textbook bills in California is a significant development in the open educational resources (OER) space. We have been working on getting the word out as to the benefits of Open Textbooks for some time now. However, when the largest higher education system in the US takes action like this – folks will take notice. In fact, I think this news could be the “tipping point” for an Open Textbook revolution.
Consider the $172 cost of the new edition of one of the top selling algebra books for one of our highest enrolled mathematics courses - Algebra. Now consider that I have over 40 students in each of my 3 sections - that is over 120 students:


$172 x 120 students = $20,640

This is a lot of money for one instructor's one semester of Algebra - now scale this up to the over 340,000 Algebra students in California and you start to see the significant amounts of money involved here!  Here is an info-graphic made by the 20 Million Minds Foundation and an open textbook savings calculator. I like to say that adopting an open textbook is like your very own local stimulus plan!
http://www.20mm.org/infographic-open-source-impact.html 
Now some might argue that the top selling textbook is better for any number of reasons... and yes it might be.  But we have to start considering student cost in our decisions to adopt.  

Is it $172 better?
Is it $100 better?
Is it $50 better?
Is it $25 better?
Can I supplement any shortcomings?
Do I have the time to make change?

I happen to think the 21st century college instructor will use a LMS to aggregate OER as a means to present a course that leverages his/her expertise. High quality modular Open Textbooks and resources are the key. Modifying open textbooks, collecting good content and building courses is time consuming. However, the benefits in course relevance and cost far outweigh any upfront effort. New editions are totally up to you and not a product of the bottom line!
We need to take the “all of the above” approach to addressing the soaring costs of education. These bills may not solve the cost issue overnight - but they sure bring the $200 textbook problem into laser focus. I truly hope the use of Open Textbooks tips - where more faculty and students become aware of their viability. 

Instructor Challenge: Start by adopting one open textbook for next semester. They are hard to find, modify, and supplement.  Some links are provided below that might help. Join the OER community:

Students Challenge: Start by searching out open textbooks and send the links to your instructors.  Sign the petition. This will be your legacy to those who come after you.

Intermediate Algebra Textbook


Dear Colleagues,

I am excited to announce that Flat World Knowledge (FWK) has just published a new textbook, Intermediate Algebra.

In order to combat soaring textbook prices, I have written this textbook in a modular fashion to maximize its effectiveness as an open educational resource. It is available under a creative commons license, has been thoroughly peer-reviewed, and is customizable using the “Make It Your Own” MIYO system. This textbook is the second part of a two-part course in Algebra. It builds on the skills learned in Elementary Algebra and blends the traditional and graphical approaches to the subject.


Used as a standalone textbook, Intermediate Algebra offers plenty of review as well as something new to engage the student in each chapter. With robust and diverse exercise sets, students have the opportunity to solve plenty of practice problems.  In addition, students might appreciate the embedded video examples.

I am happy to be a part of the solution to the current rising costs associated with one of our essential developmental math courses.  Compare this textbook to other open source algebra projects and you will find that FWK did a great job. The free to read online version makes use of MathJax and images to present the material where the Firefox web browser is recommended.  In addition, the e-textbook and printed versions are available for purchase through the Flat World Knowledge website.

Please feel free to distribute this link to your students and colleagues.  I truly believe that it will be a valuable resource.  Also, feel free to email me with any suggestions or ideas.

Thank You,
John Redden, Professor of Mathematics

Algebra eBook on Google Play

It took a while... but we were able to get our Free Algebra Study Guide onto the Google Play bookstore.  The basic steps were to:

  1. Create the e-book in the .epub format. We used the open WYSIWYG ebook editor Sigil.
  2. Create a Google Books Partnership Account.
  3. Follow the instructions for submission EXACTLY and set your price.

The Google Play e-reader is actually very nice. You can seamlessly read the study guide on many different devices.  The epub format allows for reflowable text.  Please feel free to download the book and study the mark-up in Sigil.


Doing this was a fun exercise and I hope the guide might help some folks.
