Not sure why the teachers love this so much because all it does for students is stress them out. Considering if they are required to complete and master an IXL that they are struggling on, the students can become stressed and fearful if they don't complete it and get a bad grade on it. Next, Why would you think making the grading system score on here the way it is.? It's really ridiculous it does not push or motivate a student to keep trying if they go from 75 points to 64 points. By far Math seems like the hardest category to get past on here. I don't recommend ANY math teachers to use this because it does not help students gain more understanding of the subjects. This is because if you tell them they must "master it" that's all they're gonna think about such as "If I get an 100 on this I'll pass". I honestly think that IXL just needs to be completely redone because this app is not like how it used to be, and it's an eyesore.
