Reflection of the Day: Thanksgiving

with one comment

While I would usually be posting a “Quote of the Day” at this time, I thought that with it being Thanksgiving (at least as recognized in the U.S.), that it would be good to reflect a little about what I have to be thankful for, just as I encourage everyone to do: today and every day.

My Quora Answer to: What are the problems with math education today?

without comments

I just posted the following Quora answer to the question “What are the problems with math education today?”

One of the issues with math education that is rarely considered, is a question of “what should be learned”?   While I echo other respondents who say that there is not consensus on the goal of math, if we at least assume that one important part of mathematics is how it can be used, then there are scientific methods of determining which particular parts of math are important to know for a particular context (nation, career, etc.), but I have seen little in the way of research on this, and less in the way of using the research that is available.

For example, in the U.S., not a single state nor the Common Core State Standards require students to know what a Trillion means before they graduate high school (Walker 2011), yet they are supposed to know scientific notation and imaginary numbers before graduation…  Something seems amiss with this set of priorities.

Two Amazon Cloud Reader Secrets

with 5 comments

I am overall a fan of Amazon and Kindle Edition books.  But I don’t own a Kindle and I don’t like installing third party software on my PC, so I often use the Amazon Cloud Reader.  But, there are two annoying problems that the Cloud Reader has without knowing the “secret” solutions: Linking directly to a book and copying text to the clipboard.  This morning I figured out how to do both of these things.
