Where technology hasn’t penetrated in a meaningful way is in professional development. Teachers are still “improving” their skills in more or less the same way they were decades ago. This has to change. If you’re teaching in a STEM-related area and you cannot or will not understand variable assignment, iteration, recursion, and other basic concepts — the very basics of coding — you should find a new career. I’m not saying you need to delve into pointers, concurrency, etc. Just the basics.
