I believe that this app provides students with a cost-effective way to learn sentence diagramming. From personal experience, I know that the best way to become skilled at diagramming sentences is by practicing. By providing numerous example sentences, at various levels of difficulty, this app provides students with a tool that allows them to be responsible for their own learning and work on areas of sentence diagramming that are more challenging for them. This app also allows professors to make the instruction of sentence diagramming more hands on. Because teachers can create their own examples and share them with the students, class time can be spent with the students actively working on sentence diagramming rather than just listening and watching the professor explain it.
