I can see the appeal, but have not seen the effectiveness
Community Review for NoRedInk
I feel that while NoRedInk can be useful for practicing grammar, I feel that it is not good for teaching it. The problems it gives are frequently repeated, to the point where I've done assignments by memorizing the questions, rather than knowing the content. To me, NoRedInk is better suited for an elementary school or middle school class, but not high school. A big problem I have is that it asks for the interest of the user, but instead of using them in situations that would make sense to the character, and by extension the user, it instead will just throw the name in, making it jarring, to say the least. It is good for homework assignments, with its ease of access and work-paper styled questions. So, to conclude, NoRedInk is good for re-enforcing and practicing knowledge but is not well equipped for teaching students new information.
How I Use It
My class has used it to both teach and to practice grammar.
