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

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

@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
