Consider:
-holders of advanced degrees and credentials (gatekeeping)
-assigns labour (literally called worksheets!) to pupils (proles)
-gives out sanctions, extra work, and bad reviews to punish bad work behaviour
-literally trained in discipline
-sharing of knowledge is forbidden, calls it cheating
-insists that you not work directly with your best friend, assigns you pairwork with a gender you’re not yet comfortable with
-according to most media, teachers are the most liberal profession
-creates quarterly performance reports for workers, stressing constant need to improvement (report cards)
-have direct access to whiteboard markers and notebooks, the means of instruction!
The solution to this in my opinion would be to create a new school. Call them “Academies” or something. These new schools would be constructed with the specific purpose of recruiting and teaching in a socialist way. Providing specific teacher training for these Academies is easier to have teachers accept because they know damn well they’re applying to a new and different type of institution when they apply for the job.
You construct more and more of these over time alongside the old schools and slowly phase them out. You can also gather data demonstrating that the Academies provide better results which reinforces acceptance in phasing out the old ones.
Yes this was actually attempted, but didn’t work, because the academia and broader inteligentsia resisted the attempt to replace them, and furthermore, the new socialist cadre was necessarily educaded by the old burgeoisie one.
Non European socialist countries succeeded more with this, since they started with lower level and they had actual revolutions unlike euro socialists, but the thawing after 68 got them too.
