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 […]

“Is that all we have to do?” The teacher had told them that to answer this question they needed the distance formula and the Pythagorean Theorem. They’d used the distance formula on the two points they were supposed to figure out the distance between… and were wondering whether they were done, because they hadn’t […]

I’m revising and remixing an “order of operations” lesson. IT’s all well and good, but … if you haven’t been working with me, do you already know about a good way to break the problems down as you go? Do you understand that “do the parentheses first” is more complicated than that — that […]

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 […]

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 […]

Seems my “Mathia X Review” post has replaced my “forgot the magic pen” post as the one that keeps attracting traffic. It was intentional – I tagged it — while the “magic pen” gets people looking for how to make a square root sign on the computer 😉 I also decided *not* to take the […]

Changing 8 percent to a decimal… it’s .0008, right? You take 0.08 and divide it by 100. I thought the “do it once, not twice” would work but then… “Move the decimal two places” with a very, very, very careful and explicit Placing Of The Point, explaining that 8 dollars is not the same as […]

I did a few more lessons in the assessment prep course… and YES it includes “knowledge checks” as the ‘real courses’ do. This makes me happy (especially since it makes it easier to put it away)… though it’s weird — it says I *have to do it* within 24 hours. ?!?!? And […]
