Today’s plan:   9:00 a.m. “Saturday Saunter” (usually back by noon)… 2:30 “Try-athalon”  where we ride from Neutral Cycle to yoga, rock climbing and the assorted games and funstivities at Riggs Brewery (they have big ol’ outdoor area with Jenga & bag toss & that sort of thing… it’s a reasonably awesome venue). It’s going […]

Need to get away from twitter which has a mess of stuff from another open education summit.  Sour grapes. I did the next two (now down to 16 lessons) ALEKS lessons … the figuring out angles and sides of a triangle with laws of cosines and sines.    Talk about exercises in precise attention to […]

There is/was a twitter thing on integers today.   Someone spent two weeks talking about meaning, and then … students went to “adding the opposite.” I suggested that sometimes the meaning background made the ‘rule’ easier to remember.    I had earlier in the day recalled that azaleas and rhododendrons like acid soils, and had reflected […]

Pre-emptive concept development

One of the things that wowed me about my Java I course was the ability of our instructor to teach concepts pre-emptively, consciously laying groundwork with “future common errors” in mind. We worked with the concept of “object orientation” and variables being the address where a value lived, not the value itself. He kept coming […]

We’re singing it in choral union … but not the version imprinted in my memory.  It’s on Pete Seeger’s 1963 _We Shall Overcome_ live album without the words South Africa. I wondered what the lyrics mean — the title is onomatopoeia (yes, I can spell that — “on” then as if you were spelling “tomato” and […]
