If answers to your test questions can be looked up by "cheaters" on their phones, maybe they don't need to learn them? BETTER QUESTIONS PLZ?
I grew up in Central Pennsylvania. In our School system, every student memorized the names of all Pennsylvania counties in 9th grade.
After College, I moved to Maryland (outside of Washington DC). Two years later, I moved to California. I've now lived in California for longer than I lived in Pennsylvania.
Why did I have to memorize the counties in Pennsylvania in 9th grade? It was for a test.
Rote memorization had largely outlived its value long before cell phones became prevalent. Today's schools should be teaching research, critical thinking, and information management. Teach students how to search and how to use the information they find.
@jemmons is correct. If the answers to the test questions can be found easily, during the test, they're poor questions.... and the student is learning about research ad hoc.
There are vanishingly few multiple choice tests in the "real world".
