Yes!  I have a little almost down time after lunch!

Student will be coming in tomorrow because linear vs. exponential is not clear.  So, is there anything out there that’s not procedural?

Khan Academy  , no surprise… is procedural and explains assuming you know what everything means.   The video is pretty explicitly designed to Teach You How To Asnwer Our PRactice Problems.

Then there’s a direct link to a powerpoint that in 4 slides tells you how easy and obvious it is

https://www.psywww.com/gst/linear-vs-exponential-growth.html    does a nice job (and refers to Ray Kurzweil as a “prominent inventor”), tho’ the explanation gets more challenging as it goes, assuming you don’t need practice with the concept.   A person who already had stuff in the brain to connect to things (and knew to do so) would prob’ly like this.

Learnzillion… I thought, this should be good!  It should be aimed at younger learners! but … I got “this video is not authorized to be embedded here.”   We need #OER (no, I’m not going to dig into the page code to figure out where it is).

What I’d like to see?

The psywww.com explanation with guides to get students to translate in their brains what a table would look like as a graph.     I’d like to see some examples with big and small numbers that relate to ‘real’ stuff — much like that article does, but with just a little more guidance and a few more examples.   Ideally … the learner could pick what to look at.

Out of this rabbit hole, now… b/c I’ve got a student who would be served *very* well by our sample course, tho’ she’s wanting to work on fractions (tho’ times tables are also a topic of interest) so I’d have to bring that stuff on over from the Transitions course (all paper) stuff.

Ain’t nothin’ to it but to do it…
