Of the four levels of learning, rote memorization is the lowest, easiest to achieve, easiest to test, and least useful. The student can demonstrate the ability to repeat a memorized phrase verbatim, or given a couple seconds to think about it they can rephrase it in their own words using their mental thesaurus. Multiple choice and short answer questions test rote memorization, which happen to be easy to grade, machines can do it. Rote memorization will have little effect on the student's overall behavior, if it's all you teach and test for you're not a teacher you're just cosplaying as one.

Also had to memorise it, and though its been ages, i can get the properties of some elements just by remembering +/- where on the table it is. So idk, sounds like a educational purpose :')
