Out of date and uses bad teaching methods
I have a long list of grievances with membean. What membean doesn't take into account is context and uses old outdated definitions not commonly used anymore. It's severely difficult for students with dyslexia to use since spelling counts and many of the words look alike. Some days you're given up to 15-20ish new words and when you have to do this 3-5 times a week it ends up being overwhelming. They try to teach you definitions by showing pictures that have nothing to do with the word (for example the picture for "arbiter" is a man in jorts holding a dog, and "frivolous" is a toddler in a shirt that says "i love my mom). The site is fine during stage 1 but as soon as you move on from that you have multiple words that start with the same 2 letters and have the same meaning and you just have to guess what it is, and when you have 300ish words in play it just becomes a guessing game for the spelling ones.
I think it has to potential to be good, it just needs a lot of changes.
How I Use It
I'm a student who uses this 5 times a week for my AP Lang class
