Downloaded the sysinternals zoomit utility so I could annotate the screen as well. Has worked well for the students and, as a bonus, is a lot more fun for me.Gordonhttps://www.blogger.com/profile/04585862919497147034noreply@blogger.comtag:blogger.com,1999:blog-18677687.post-91861063089167964782020-05-08T21:56:40.434-04:002020-05-08T21:56:40.434-04:00The Harkness Table, at least by that name, started...The Harkness Table, at least by that name, started here in New Hampshire at Phillips Academy in Exeter. Still the main model for teaching there. Works best with smaller classes of course.<br /><br />https://en.wikipedia.org/wiki/Harkness_tableAlfred C Thompson IIhttps://www.blogger.com/profile/06011086242006020298noreply@blogger.comtag:blogger.com,1999:blog-18677687.post-91480932148975954832020-05-08T19:12:11.749-04:002020-05-08T19:12:11.749-04:00Harkness table!

Some of my math classes are small and work this way.

It is not for everyone. I had no problem since I am an engineer and did just about everything in software engineering for ~25 years. My first tome I taught a CS course was a semester elective in Processing. I reconfigured the room into a monster Harness table. Kids faced each other and mostly everyone had a laptop. Kids loved this class. You faced each other and I projected my laptop with the Processing environment. In a short time kids were asking to be the “driver.” Even kids on lunch tried to crash my course cause it was “real.” It was not all about mistakes, but they learned from watching how “volunteers” would attack some snippets of code. We doodled on paper and whatever how to attack problems and communicate our ideas. Best is that we all modeled how real life teams work on tackled novel tasks and often we came across stumbling blocks. ... something other classes with every minute with prescribed slides could not do. The room was always packed. Yeah I got hell for not “teaching” the boring way at the front professing to them through my boring slides with perfect code where everything was beautiful and perfect. I would constantly be in debates with administrators who had no clue. The fact that my classes scored very well in my tests and standardized tests baffled the administration. The fact that they constantly turned away many students from this class might say something. Students want a realistic class. Yeah I had a topic and a good idea how to motivate the class to help me “discover” solutions, but they drove the class to learn computational thinking, algorithm design, debugging, design, redesign, iterative improvements, etc. Beware of clueless administrators. Yep I was told to put the chairs/tables back into a grid and it was overcrowded. One week later I was asked if I could put the class the way it was before. Kids loved the Harkness table Looking at each other and a computer and just talking and thinking and coding. After a while the kids finally realized they could help each other out and I came in to oversee common or big problem to address with a little auxiliary mini lesson which drove administrators crazy cause it was not in the lesson plan. Just In Time learning or Just In Tine teaching was anathema to them. Oh yeah I sometimes sat behind the computer wired to the projector mainly when we had a new topic too introduce it, but I backed off and would randomly sit on the perimeter of the “table.” Kids had no idea where I would sit ... ok that was funny. Live coding or live teaching any topic is a sign the teacher is knowledgeable and also confident to present and teach the material to newbies even with the periodic “mistakes”. Some deliberate some not. Beware administrators who have no idea what you are doing. Their ignorance can hurt your valiant attempts at reaching students and get them excited about CS.

I was also transitioning from Python 2 to Python 3. What a mess. I could not for the life of me keep the syntax straight. I would pseudo-code something on the board then start to code it up. Half way through I would notice the kids looked really confused (more than normal). I would look at the board. Nuts, wrong language.<br /><br />The Python 2 to Python 3 seemed to be the worst. Little changes were made that were just enough to really mess things up.Garthnoreply@blogger.com
