Lowell Thomson @ThomsonScience Nice! I'ved used an M&M lab. Guess number of M&Ms in the jar (using problem solving analogous to mole). Closest wins M&Ms. 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience Are students using a tablet? Of so, one of the iPad apps such as GoodReader might work. Penultimate can save to Evernote. 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience Curious of there's something special about iPad here versus any laptop? (Moving to Mac/iPad school next year...learning as I go.) 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience I've tossed this idea around a lot. Some years I think about scrapping SF and rule of 5. Others I don't. Time better spent on other? 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience Why did I get a "bait and switch" when I looked for prices to upgrade? Offer was 50% off ($37-ish) yet I was charged $75. 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience Bait and Switch from ? "Click to upgrade for 1 year plan, 50% discount." Then I was charged full rate. Not a happy camper. 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience (2/2) It always gets them to question WHY!?!?! That is what I like. But every year I wonder if it is time well spent. 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience I go back and forth on whether it matters too. So infrequently needed. I like the thinking it inspires in my students though. (1/2) 6 years 10 months ago Reply Retweet Favorite
What Would NdT Do? @wwndtd I learned it in HS, but haven't used it (grad school, internships). Current txtbk doesn't have it. Curious about consistency 6 years 10 months ago Reply Retweet Favorite
What Would NdT Do? @wwndtd Thanks, I get it. But I still don't know people who actually use it in an industry setting 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience (2/2) I don't recall original source of the rule itself. (Textbook of some sort.) The logic made sense, so I use it. 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience And here's a graphic that explains the logic. The graphic is my own from Excel. (1/2) http://t.co/0pPN1rx7WI 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience When you say "don't use a 5 rule" does that mean round up with 5 as the default? Or just letting Ss choose whether to round up w/ 5? 6 years 10 months ago Reply Retweet Favorite
Lowell Thomson @ThomsonScience And I missed it too, asleep due to time differences. I'll catch up later. 6 years 10 months ago Reply Retweet Favorite
What Would NdT Do? @wwndtd I don't use a 5 rule, but know a diff one from yours. What's your rationale for using it? 6 years 10 months ago Reply Retweet Favorite
