Charles Coomber, a Multiple-Subjects teacher from San Diego has taken to YouTube to deliver a lesson about Angle Vocabulary using in-game marker pens and planks of wood. [widget path="global/article/imagegallery" parameters="albumSlug=half-life-alyx-virtual-lesson-screenshots&captions=true"] This homeschooling stroke of genius is made possible by the sheer level of detail in the opening moments of Half-Life: Alyx, which lets players draw on the windows in Alyx's greenhouse. Coomber leads his students through the hallmarks of complementary and supplementary angles with serious charisma, using window panes and a set of coloured markers. At one point, he even brandishes a plank of wood for a physical demonstration. Coomber ends the video with a challenging problem in Alyx's surveillance room, erasing part of her detailed Citadel layout in the process...

This clever remote teaching method is clearly a response to the COVID-19 crisis, which has led countries to close schools and forced teachers to adapt to provide learning.
