Pros: The visual upgrade is nice, and live player rankings could motivate some students.

Cons: Little foundational instruction or scaffolding, some errors, and time constraints all hinder learning.

Bottom Line: This is a fun, casual option for some parts-of-speech practice at home, but the lack of rigor means it's not currently a recommendable option for learning or classrooms.

Teachers could currently assign this app as a critical thinking exercise for students who are already well-versed in the parts of speech, challenging them to screenshot specific exercises and diagram them in more detail. For instance, students could be challenged to find examples of different kinds of nouns or verbs. Students could also give feedback on sentences to the developers; however, to do so they'll need to shift their minds (and habits) out of game mode.

Grammar Ninja is an app where players hunt down all instances of parts of speech within sentences. Students race against the clock to tap the number of correct words shown at the bottom of the page. Tapping a word lobs a throwing star at it. If the word is correctly chosen, the throwing star stays. If the word doesn't fit the current part of speech, that word explodes and the correct part of speech for that word is shown. If students keep tapping incorrectly, the correct words will be highlighted for them. Incorrect taps each add five seconds to players' scores at the end of the mission.

The app includes a few tutorial missions that teach students how to play and attempt to familiarize them with these parts of speech: nouns, verbs, pronouns, adjectives, adverbs, conjunctions, prepositions, particles, and determiners. There are also some featured missions that are free and updated every six hours, providing fresh content. There are also regular missions that include topics such as "Cool Facts," "Jokes," and excerpts from various public domain literature, such as Alice in Wonderland. But to play the regular missions, players must either watch an ad or unlock it with diamonds, the in-game currency. Some regular missions have three difficulty levels: Simple (nouns and verbs only), Standard (adds adjectives, adverbs, pronouns, and conjunctions), and Expert (adds particles and determiners).

The faster students complete missions, the more points they receive and the better ribbon they earn (bronze, silver, or gold). Students can share or save their results. There are player rankings based on how many points players have earned. The players on these high-score listings periodically receive extra diamonds. Just doing well on missions can also earn them diamonds, but players can spend real money for diamonds as well. The game regularly asks players if they want to connect to social media accounts or to invite a friend to play.

Grammar Ninja has made some major visual improvements since it was originally released and feels and plays like popular games that students already enjoy. However, it falls a bit short of what educators and learners expect and need. It's also worth noting that the playful ninja aesthetic, while not necessarily offensive, could be seen by some as insensitive.

Success in exercises isn't just about tapping the correct words, but doing so quickly. Thankfully there's no on-screen timer, but students will still feel the pressure to answer quickly when they see their score at the end. While this is a great mechanic for a general consumer audience, it could lead students -- especially those who struggle with parts of speech -- to tap indiscriminately, or to not think deeply about sentences. Similarly, Grammar Ninja aims to acknowledge how the same word can be a different part of speech based on sentence context, which is important for students to understand. However, during testing some words were associated with parts of speech that were possible for those words but didn't fit the contexts of the sentences. (See one of the images included with this review.) Grammar Ninja also struggles with more complicated word formations, such as compound words that can force players to make some confusing choices. For example, in an exercise identifying nouns, the compound noun "Blue Jay" was split into the words "Blue" and "Jay," requiring the player to identify both words as separate nouns. There are also some finicky details like needing to tap specifically on the "'s" part of "it's" when identifying a verb that, combined with the other issues, could frustrate or confuse students.

Lastly, while Grammar Ninja usefully adds complexity by expanding the parts of speech covered from simple nouns to trickier things like adverbs, there's room for more scaffolding, instruction, and complexity within parts of speech. It'd be helpful, for instance, to build players from common nouns to gerund nouns or from action verbs to auxiliary verbs.

Overall Rating

Engagement

Chasing award medals, in-game currency, and top rankings will motivate some students, but being timed will fluster others. Mistakes and quirks could irritate students.

Pedagogy

Brief grammar descriptions, and a lack of scaffolding, don't properly prepare students for the sometimes complicated sentence constructions. The fast-paced gameplay can hinder reflection.

Support

The app has tutorial levels that introduce play and parts of speech. There's a lack of useful feedback on learning.

Add a competitive element to a parts-of-speech review.
Grammar Ninja sounded like a tool that would review several aspects of grammar. I wish it offered comma rules or at least independent/dependent clause identification. As far as I can tell, it just does parts of speech. It does provide three levels of difficulty, though. I liked that the site offers helpful clues/definitions to the students. I also like that the time commitment is minimal. It could be used as a quick formative assessment if your level requires mastery of this grammar concept.
