We are partnering with AFIT in Dayton, Ohio to support 1-2 paid summer fellowship positions for teachers to create classroom activities that mix CS, science and mathematics concepts! Key goal is to broaden the "pipeline" of students who receive CS training http://go.osu.edu/teacherapp pic.twitter.com/eKz2Y6VVDy

One of my Calc 3 students is taking an accredited online course that uses free YouTube videos. But, the $168 textbook is a barrier.
#MTBoS Let's spread the word to instructors: it's not just video... there are#openaccess textbooks too! Just ask@LibreTexts or@AIMathematics!pic.twitter.com/LgjCCB0BJf

I'm definitely keeping this resource in mind for my multivariable

Retweeting this so I remember to check out this blog before the next time I visit my nieces and nephews! Sounds like a great resource. Now I'm wondering if any of the activities I came up with and tweeted about were already on
@mikeandallie's blog...https://twitter.com/mikeandallie/status/1212150328604418052 …

If you're interested in interactive
#OpenAccess textbooks, or in visualizing complex analysis, check out this new online book by@PonceCampuzano, built with free technologies like#geogebra and#p5js!https://twitter.com/PonceCampuzano/status/1214850688506716160 …

WHY are the slopes of perpendicular lines opposite reciprocals? Here's an elementary, literal back-of-the-envelope proof. Coincidentally, I've found a new application of

Currently, journal articles based on federally funded research must be made free w/in 12 months of publication. A new proposal would eliminate the wait; some publishers & academic societies are opposing this

Kids can have fun trying out different strategies, which can lead them to discover search algorithms! https://en.m.wikipedia.org/wiki/Search_algorithm … Linear search is a simple one; binary search is depicted in the first tweet.

2/Rules: All agree on a whole number n for each round, e.g. n = 100, and a player to be the arbiter, e.g. P1. 1. P1 chooses a number m from 0, 1, ..., n and keeps it secret. 2. P2 guesses until determining m. Optionally, winner can be the player requiring the fewest guesses.

1/Yesterday, my niece discovered a known algorithm while playing a game I made up on a family trip called "Guess My Number." She remembered the game over a year later and spontaneously asked to play it! I'll share the super simple rules in this thread.

#MTBoS: Do you cover probability in#calculus class? It motivates improper integrals / infinite series, meshes with physical applications (probability is analogous to mass), and supports science and statistics! In the curriculum, maybe it could "displace" fluid force?pic.twitter.com/PgX3c1EsqN

Here's the code for computing Φ using Taylor series: https://www.khanacademy.org/computer-programming/normal-distribution-via-taylor-series/5258753519616000 … Again, all the values I tested match the entries in standard reference tables. Very satisfying!

Here's the code for computing Φ using Simpson's rule: https://www.khanacademy.org/computer-programming/normal-distribution-via-simpsons-rule/4613410532589568 … There's not much code. It's mostly comments (including an explanation of the mathematics used to bound the error). It works pretty well! The values seem to match standard reference tables exactly.

You can try the interactive app and see my
#code for it, hosted@khanacademy. (Their Intro to JS course, led by@pamelafox, does a great job teaching the coding concepts I used.) https://www.khanacademy.org/computer-programming/interactive-normal-distribution/6221313412710400 … The core code that computes Φ is simpler. I'll share that next.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
#MTBoS Every stats student gets to know the standard normal table. But, who needs a table when you can program a computer to do the#calculus on the fly? In this thread, I'll share code for two methods: Simpson's rule and Taylor series. Either would make a great student project!pic.twitter.com/QBcutAhJSUPrikaži ovu nitHvala.

QUESTION FOR MATH TEACHERS: Solving equations is a reasoning process, and standards correctly insist we teach this. Logical connective notation makes the reasoning explicit. It's concise and makes ideas like extraneous solutions feel natural! Would you teach this notation?

#MTBoS Bitcoin uses#calculus, specifically geometric series, to model mining a finite resource: the first block contained a mining reward of 50 bitcoin, and this reward is halved every 210,000 blocks (~4 yrs). Can you solve for the long-run supply? Fig. by@random_walker et al.pic.twitter.com/oBQLZJINBx
