Advocates often claim new computing environments will immediately boost productivity, a belief often based on intuition rather than evidence. Decision-makers may wrongly assume their own ease of use on a platform applies to everyone. Implementing a new computing environment can delay projects and increase costs with uncertain benefits. When this switch affects schoolchildren's learning, the consequences are more significant. Moving a large number of students to a new operating system like MacBooks from Windows could disrupt education. Even individual students transitioning between different systems face challenges. Teachers introducing new platforms like Minecraft for learning adds another layer of complexity. The rapid changes in Learning Management Systems and AI edtech tools also impact students. Theodp questions the amount of learning lost during such transitions and the return on investment. Ultimately, the costs associated with switching between Windows, MacOS, and Chrome are substantial and multifaceted.
