For me, this is the best method to solve #quadratic #equations (better than completing squares, general quadratics formula, factorization, ...)

It's easy to understand, it works with $a \neq 1$ and it has meaning.

It's based on change of variables and #symmetry

Someone very close said to me that boys putting off hairclips are "not normal". Her daughter did not understand why (16 years old). Her son talked to her "this is girl stuff" (4 years)
What amount of work to the equality of persons!!! A great pitty

I realize that #systems of equations which is single unique solution could be viewed as determining the weight of #barycentric points to get one specific point: example:
{x - 3 y + z = 2, 3 x - 4 y + z = 0, 2 y - z = 1} is equivalent of xA+ yB + zC = D, where A=(1,0,1), B=(3,-4,2), C=(1,1,-1), D=(2,0,1) are points: x, y, z are the barycentric #coordinates of D in A, B, C system.

Una manera de donar protagonisme als alumnes és donar-los l'oportunitat de triar el tema que volen veure. Avui els he donat a triar: què voleu veure funcions o estadística. Els he dit de què anava cada cosa i ELLS han triat. Al final farem estadística

L'ideal seria que cada alumne pogués triar *el seu tema*, però com estan les coses ara (ensenyament semipresencial) ho veig difícil.

Perhaps some teachers would be interested in these conferences in #LibrePlanet2021

- Giselle Jhunjhnuwala & Charlie Koch "Gamifying education the libre way" https://libreplanet.org/2021/speakers/#4821
- Victoria Schuster, Dryden Wiebe & Vala Vakilian. "Plom: Paperless Open Marking" https://libreplanet.org/2021/speakers/#4823
- Javier Sepulveda Sanchis. "Remote education: My children's freedom and privacy at stake" https://libreplanet.org/2021/speakers/#4570

@opensourcegardens Perhaps you were interested in this association which promotes local varieties of seeds and plants: https://www.varietatslocals.org/

This is "Associació de Varietats Locals" in Mallorca.

Why we don't trasnsform or create rich activities for classroom using the same model as "World Game Jam": 48 hours of teachers gathered and creating *your* own activity.

I think designing activities is really a thing that most teachers I know do on their own.
#teachers #activities #create

Anyone has an open-source alternative to #gsuite (for education)? I try to find it out in search engines and no result found. My ideal would be #nextcloud + #moodle integration.

I'm concerned with privacy issues and make G**g** more powerful each time

@Ubports
@postmarketOS
Perhaps you could benefit each other. At last, there is a common aim: to able to install a GNU/Linux distro in our mobile/tablet.

@write_as Can you please hurry up the release of the open source write.org? I want to know how it is implemented and if I could use it to my personal notes like #tiddlywiki

I completely agree with Céline Alvarez in "Las leyes naturales del niño" (spanish): direct instruction is not natural https://scholar.social/media/MA0DopBhv5gKUaHeX9Y
