THE RADIX ENDEAVOR

http://radixendeavor.wordpress.com/2013/09/03/play-the-radix-endeavor/

On Tuesday, the Education Arcade of The Massachusetts Institute

of Technology (MIT) released the beta version of a massively

multiplayer online (MMO) game for high school students to learn

geometry, algebra, probability, statistics, and biology.

The Radix Endeavor, aligned with the Common Core State

Standards (CCSS) and Next Generation Science Standards, takes

place in an earth-like world during a Renaissance-like era.

Students play characters who take on quests, each tied to a

particular content area. Through exploration and MMO

collaboration, teens conduct their own experiments to develop

hypotheses and figure out how the mathematical and biological

systems function in Radix's virtual world, while taking

advantage of the game-based environment to, for example, speed

up time to see the outcome of a decision that -- in a

real-world experiment -- would take months.

Start your own adventure on the island of Ysola by creating a

temporary account (feel free to use a fake email address),

selecting a "teacher" account, entering "MIT" as your school,

and choosing it from the drop-down menu, too:

http://www.radixendeavor.org/

The Education Arcade seeks high school math and biology

teachers to enroll their high schoolers in a large-scale pilot

test this semester. To join the pilot, see other ways to get

involved, and receive updates, visit

Radix is funded by the Gates Foundation, and under development

at the MIT Education Arcade in collaboration with Filament

Games. Learn more, including how to participate in professional

development at MIT, by checking out

PoW taking place: math problem-solving moment of the week

"I knew that was the key piece of information because nothing

else paved the way. I thought that 4 multiplied by an unknown

number added to 3 (4 and 3 being the numbers in the ratio)

multiplied by the same number would be 154. A more efficient

way of saying that is 4a + 3a = 154. I am not so good at

algebra so I tried dividing 154 by 7.... At first, I had

accidentally erased the top of the 9 in 297 and mistook it for

a 4. Later I saw my mistake and had an 'aha!' moment.... I was

stuck at that part for quite some time. Then I remembered that

a percent is just a different form of a fraction...."

GRANDMA GOT STEM

http://ggstem.wordpress.com/

This Sunday may be Grandparents' Day, but a math professor

began blogging earlier this year about public awareness and art

projects that use grandmothers' pictures, names, and

connections to science, technology, engineering, and

mathematics (STEM).

With "Grandma Got STEM," Harvey Mudd College's Rachel Levy

"counters the implication that grannies

(gender + maternity + age) might not easily pick up on

technical/theoretical ideas." Levy has already posted over a

hundred times, each named in honor of a "STEM-ma" (with that

100th post recalling one of her own, especially endearing,

STEM-related memories: "the windshield factor"). Along the way,

she has featured dozens of mathematicians, such as

- Karyn Traphagen, Executive Director of ScienceOnline2013

- Carol Jo Crannell, solar astrophysicist at Goddard Space

Flight Center

- Shakuntala Devi, a "human computer" and Guinness World

Record holder for lightning-speed calculations

- Maud Menten, of the Michaelis-Menten equation

- "We'll just call her Dorothy," a computer programmer at

Sandia National Laboratory and NASA's Jet Propulsion

Laboratory with security clearances that gave her access

to nuclear secrets

http://ggstem.wordpress.com/category/mathematics/

Levy, whose research interests include the hydrodynamics of

whale flukeprints, hopes to involve more school-aged children

in the project. She has worked with teachers to create school

assignments, and has started to make contact with leaders of

after school clubs. Grandma Got STEM has already featured

student submissions from preschoolers to high schoolers, who

have interviewed their own grandmothers or scientists in

their communities.

Now taking place: math education conversation of the day

"There have been great discussions on the listserv and it would

be wonderful to continue them in person. On a more personal

note, I will be at the fall conference and would love to speak

and brainstorm with other Algebra teachers. I plan to modify

some of the lessons in the modules."

TRAVELLING SALESMAN MOVIE AVAILABLE FOR PRE-ORDER

http://www.travellingsalesmanmovie.com/

Starting Tuesday, you can download the intellectual thriller

about four mathematicians that swept best feature film, best

actor, and best editor honors at the 2012 Silicon Valley

Film Festival.

First featured in these pages last June, "Travelling Salesman"

focuses on the ethical implications of four fictional

mathematicians' breakthrough discovery about the most vexing

open question in computer science. To learn more about the

mathematics of traveling salesman problems, check out the Ask

Dr. Math conversations

Traveling Salesman Problem: Is there an easy solution to the

"Traveling Salesman Problem"?

http://mathforum.org/library/drmath/view/52267.html

A Quick Overview of P vs. NP Problems: Can you explain what P

and NP problems are at a level that a high school student

can understand?

http://mathforum.org/library/drmath/view/71720.html

Purchase the digital version of the movie -- with instant

streaming and HD, DRM-free downloads for iPads, Xbox, and any

device that plays MP4s -- directly from the filmmakers or
