How I Use It
Grammatica does a good job of correcting errors in a student's work, but not in teaching them what was wrong and why the solution is correct.
Overall the tool serves as a good way for students to correct their writing and create better quality papers, but it is on them to take the extra step to figure out what they did wrong. Since they are not encouraged to do so and given the answer, this is often not to be the case. It is a great tool for final correction, but shouldn't be relied on for education purposes.
