Teach Foundational Language Principles (CACM May 2015, pp 30-31)

The authors point to teaching programming languages as opposed to logic as being a seriously weak spot in computer science education. While the “Hour of Code” has a lot of appeal and can introduce people to computing, they point out that new computing languages are continuously being developed to try to solve new problems. They make numerous examples and point to Dijkstra's classic “Go To Statement Considered Harmful” as examples of how understanding a problem has lead to new languages and new language structures.

Education: What Are We Doing When We Teach Computing in Schools? (CACM May 2015, pp24-26)

This article initally caught my attention with it's graphic and caption “SCIENCE:Gravity makes haveier things fall faster.” The author goes on to recount her experience with just such a poster in a local elementary science fair and her lack of success in having it taken down. The point: we have started pushing instruction of computing (and programming) into schools where there are non-specialist teachers who are expected to understand the material well enough that the students come away with correct knowledge. 

Feeds Updated

A lot of the incoming RSS feeds were dead, so I spent a couple of hours today to find replacements. This is as much for me as for you so I have one place to go for my space and astronomy news. I need to put togther another physics set of feeds, too, then I'm good.I also finally took the time to get the image links working correctly. The URL rewriting was a bit finicky and things had to be done in the right order, but it all appears to be working now.

So what exactly has happened to this site....

I've clearly been on a long hiatus from posting here, largely because life has a way to doing that to you from time to time.... I've still be out doing some observing, playing with equipment, and more. But I have two teenage boys now and have taken on the role of Scoutmaster in a local Boy Scout troop.

NSTA STEM Expo 2013

I spent three days at the NSTA STEM Expo in St. Louis last week and over the next few days, I'm going to try to do a few posts related to the sessions I attended and things I learned (and cool freebies I learned about on the web).This is the second year I've attended, and while most of the sessions were not, unsurprisingly, about astronomy, they were all relevant to science and science education which is an underlying theme for my interest in astronomy.
