Google doc

Collaborative writing output sample (read only)

Wolfram Alpha

Computational tool (I admit this uses some kind of AI :-), especially in the "natural language" mode)

GeoGebra

Computational tool - graphing output sample (screenshot)

Octave

Computational tool - online Matlab instance

Dudle

Simple polls without ads, convenient/sufficient for planning educational project meetings and events

Discord

Social network/app originally developed by and for gamers. Convenient for learning support, because "it is where the students are" (Tørris Koløen Bakke, UiT).

Online learning support conversation sample (screenshot). We use MS Teams because we are only allowed to communicate with students through official university channels. Only a few ask because it is not where the students are. :-(

TALMO

Teaching And Learning Mathematics Online. An inspiring example of curated videomaterial repository. No matter you like math or not, the arrangement and structure are well done.
