eLearning Tools for STEM

For anyone who has ever had trouble convincing your administration to give you the proper tools to teach online, I give you this little gift: eLearning Tools for STEM, published today in eLearning Magazine. The tools for STEM eLearning Tablets Recording & editing software Jing Equation software and training Synchronous communication system Online homework system Other head-turning resources for STEM Wolfram Demonstrations Digital libraries (a lengthy list) Video collections (another list) TI-SmartView Other tips (about accessibility, computer labs, etc) can be found at the end of the article. You can read about all the tools, and why I recommend them, by going to the article, eLearning Tools for STEM.

Jing Refresher and Myths

Just in case you’re getting back into the swing of things this fall and finding yourself as forgetful as me, I thought I’d give a little Jing refresher here and remind you of some resources. First, a little reminder of how Jing works! Myth #1: I use Camtasia so I don’t need Jing What about your students? Teach them to Jing and they can share screen captures and short videos with you!  Not enough motivation?  It’s much faster to whip out Jing and record a response to a student’s question than it is to create, edit, and produce a Camtasia video. Myth #2: The 5-minute time limit is a problem. No, the 5-minute time limit is a blessing.  Who really wants to watch more than 5 minutes of Internet video.  There’s great value in learning to get your message across in a concise little package.  When you ask students to submit videos to you for grading, you’ll quickly appreciate the 5-minute limit.  Plus, there’s nothing to stop you from recording a 3-part series if you really must get 15 minutes of information out there. Myth #3: The EMBED button is gone! The embed button is gone from the standard Jing installation, but you can get it back with about 2 minutes of time invested.   Use one minute to watch how to do it.  Use the second minute to do...

Online Course Design for Mathematics

This week I have been participating in the MAA PREP course, Calculus: Online and Interactive. I was asked to give a presentation on online course design for mathematics, and the presentation was recorded. This is a loooooong one (two hours), but it is packed with information, ideas, and design tips.  If you’re going to teach online for the first time, or just want some guidance for revamping your online math course, I think you’ll find it helpful. There are nine parts to the presentation: Virtual Classroom (overall course design) Interactive Learning Materials Video Lessons Online Homework Blended Environment Student Engagement Equations and Graphs Orientation and Setup The Math Testing Issue You can view the slides below or here. Online Course Design for Math Uploaded on authorSTREAM by wyandersen | Upload your own presentation To watch the whole presentation, go here to the Adobe Connect recorded webinar. There are also two mindmaps that you might want to investigate that are mentioned in this presentation: Online Math Using the Internet to Spice Up Your Math Course You may also be interested in the online Calculus textbook, Calculus: Modeling and Application, 2nd edition, which may be used free for the next academic school year (supported by an NSF grant).

Don’t get WolframAlpha Implications? Try these examples.

Wolfram|Alpha is a “computational search engine” built by Wolfram Research (the developers of Mathematica). W|A (pronounce this as “walpha” if you’d like) is similar in appearance to the search engines that we are used to and easy to use. It’s not that W|A will replace other search engines, because it won’t. It’s more of a missing piece in the search engine puzzle. W|A provides a collection of data, formulas, computations, and interpretations that are different from other search engines. Although the media has stressed data-driven examples (for example, type your first name to see a graph of the frequency of that name over time), the ability of W|A to function as a combination of CAS and natural language computational system is stunning. Let me illustrate with a couple of examples for you to try yourself.  Simply follow the links below to see how W|A handles these search requests: • 126 (make sure to click on “other historical numerals”) • convert 125 m^3 to gallons • sphere r=7 cm • Line (2,7) and (3,1/2) • Solve x^2-6x=16 (make sure to click on “show steps”) • 4 – x^2 • Triangle 7,8,9 • x^2-y^2=9 • limit x->3 (x-3)/(x^2-9) (again, make sure to click on “show steps”) • integral (x^2)sin(x^3) (“show steps”) • sum 1/n^2 • New York City, Chicago • convert 78 to base 5 There are several differences between W|A...

Implications for Math Instructors

They say a picture is worth 1000 words.  Then here are about 15,000. I’ve taken screenshots of several examples of the algebra through calculus that WolframAlpha will do. You can see the album of screenshots here. I’ll let you see the implications for yourself.
