Technology influences cognition

That technology can influence cognition should be painfully obvious when you examine our primary technology of communication – language. Someone who knows a language cannot choose to ignore that language when confronted with it. If you are a literate person, letters arranged together do not appear randomly placed, they form words. When someone talks, you […]

Glass is half-full

A CNN report on a survey done by the digital security company McAfee (which reads more like an ad than a report – what happened to investigative reporting?) has some startling statistics. According to the CNN sanitization of the survey: Clear browser history (53%) Close/minimize browser when parent walked in (46%) Hide or delete IMs […]

Kindergarteners programming

Here are two sample programs from a pair of kindergarten classes today (I took screen-shots of their program, and cropped them to fit in this blog).   Program 1:   Program 2:   I started the kindergarteners off the same way I started off third graders last week – they were to program me, and […]

Many ways of learning how to ride a bike

When I learned how to ride a bicycle, I practiced with training wheels first because my parents thought that it would be too difficult for me to learn how to balance myself, steer, and pedal all at the same time. I eventually learned how to ride a bike without training wheels but it was challenging […]

Logo(ish) programming in the browser

  I found out through Reddit about a new visual programming language that runs in the browser called Blockly. The system looked pretty good, but wasn’t quite right for my students. Fortunately the Blockly code was fairly easy to figure out, and so I hacked around a bit this weekend, and put together a simplified […]

Eduglogger survey

Questions and answers below.   Blog URL:   What do you blog about? I generally blog about education, often focusing on issues such as improving mathematics […]

Programming with 3rd graders

  I did two things I’ve never done before – I taught 3rd graders, and I introduced elementary school kids to programming. Yesterday, I started off by talking to the kids about how programs work on a computer, using the analogy that a programming language is like talking to a computer. If you can speak […]

The difference between instrumental and relational understanding

  I recently found this article written by Richard Skemp that Gary Davis (@republicofmath) highlighted on his blog . I recommend reading the whole article. Skemp describes the difference between instrumental and relational understanding, and how the word understanding is used by different people to mean different types of understanding. He also makes the observation that what we […]

Children are not railroad trains

"Timetables! We act as if children were railroad trains running on a schedule. The railroad man figures that if his train is going to get to Chicago at a certain time, then it must arrive on time at every stop along the route. If it is ten minutes late getting into a station, he begins […]
