Instruction > Correction

The work of a writing instructor never ends. Grmr.me can cut down on that work and improve student learning by providing instruction on common writing errors rather than simple correction. 

Short URLs

Identify an error, provide a short URL. How many times have you written comma splice on a student paper? Hundreds? Thousands? From now on, simply write grmr.me/csp in the margin, and lead your student to effective learning.

Writing Felonies

We call the most common errors writing felonies. Each writing felony has a video that demonstrates how to identify the error and how to correct it. Below each video are interactive quizzes that confirm  a topic is mastered. Writers who pass the assessments earn a badge.
