WHO: Teachers looking for flipped classroom, grammar practice, and/or extended lessons on grammar.
HOW: Teachers can register for an account and create a class, or students can create an account on their own. Lessons include videos which allow students to pause and repeat unclear items, as well as exercises to practice what they have learned. There is also a reporting feature which allows teachers to quickly see how students are progressing.
WHEN: Grammar Flip would be a great option for the Flipped Classroom. It could also be used for supplemental material for those students that need more assistance or for students that would benefit from working ahead.
