Hi everyone!

I am a tutor seeking advice regarding sentence diagramming software. I teach international ESL university students and have found that many find diagramming sentences a more effective learning method than other methods I have tried (perhaps this is because diagramming sentences does not involve even more words?) Anyways, I am currently browsing the wide selection of diagramming software on the web, and would love any advice on what seems to be the best value.

Thanks so much!
