Learning at Scale Slides from ICTCM

Learning at Scale: Using Research To Improve Learning Practices and Technology for Teaching Math In the last 5 years, there has been a rise in what we might call “large-scale digital learning experiments.”  These take the form of centralized courses, vendor-created courseware, online homework systems, MOOCs, and free-range learning platforms. If we mine the research, successes, and failures coming out of these experiments, what can we discover about designing better digital learning experiences and technology for the learning of mathematics? Learning at Scale: Using Research To Improve Learning Practices and Technology for Teaching Math from Maria Andersen   Possibly...

Celebrate the Errors in Math Practice

Dear math students, As you work through your mathematics practice, I’m going to challenge you to embrace making errors in an entirely new way.  Many students believe that every problem in math homework should be perfectly constructed with no errors. It might look something like this:   But when it’s time to study after the initial problem run-through, what does this perfectly constructed problem say? Does it coach you on remembering how you struggled? Does it remind you where you made an error? No. When you make an error as you’re working a problem, please don’t erase it from the face of the...

WolframAlpha Facebook Report

This is a delightful exercise that everyone seems to love. WolframAlpha will provide you with an extremely detailed analysis of your own Facebook data including visualizations, world clouds, graphs, and more.       Here’s how: Go to Type “Facebook Report” and execute the search. Allow WolframAlpha to have access to your Facebook account by clicking on “Analyze my Facebook Data” and following the directions. Wait while the data is analyzed. Note: Sometimes the report seems to stall after 100% of the data is analyzed. If this happens, simply repeat steps 1-3. The second time, the report seems...

Data Sleuthing

Khan Academy Idaho is a grant-funded initiative to help K-12 teachers in Idaho integrate digital devices and the Khan Academy program into their math classrooms. Yesterday I gave a keynote there called “Between a Rock and a Hard Place” about (1) the challenges facing math educators and (2) Data Sleuthing, a way to encourage math curiosity and data literacy in students. Resources from this presentation: Wolfram Alpha Gapminder Google Trends Many Eyes Google Fusion Tables Google Public Data Homework from the Presentation TED Talks: Hans Rosling Flowing Data CoolInfographics Guardian Data Blog Edward Tufte Measure of America InformationIsBeautiful...
