We started AAC Awareness Month by posting about core vocabulary. If you missed the post, check it out here. There’s often conversation about core vs. fringe on Facebook groups and amongst teachers, SLPs, parents, and other AAC stakeholders. We think it’s really important to think about ALL the vocabulary that is important to our students’ language development and not think about vocabulary selection in terms of core OR fringe.
While our main focus in speech-language therapy often revolves around core vocabulary, we frequently target nouns that are either important to our students or that are commonly occurring. We tend to split vocabulary into three categories – core vocabulary, personal vocabulary, and fringe vocabulary.
Core Vocabulary – approximately 200-400 high frequency words that make up about 80% of all words we use to communicate.
Personal Vocabulary – family, teacher, and friend names, favorite foods/ tv shows/ songs/ etc., common places, etc.
Fringe Vocabulary – low frequency vocabulary, mostly nouns
We spend most of our time (about 75%) on vocabulary instruction related to core vocabulary and personal vocabulary. But we also pepper in some fringe! Especially fringe vocabulary that may be used more frequently (e.g. furniture, utensils, rooms, toys, transportation, some foods, etc.).
Check out some slides below that we use to describe the differences in vocabulary.
Earlier today, I texted my roommate and analyzed the conversation to take a look at our core to fringe ratio.
Of the 47 words used, 44 were core and 3 were fringe. There were a couple of key take-aways I took from this language sample. There was a wide variety of core vocabulary used in this sample: 10 pronouns, 6 interjections, 11 verbs, 5 adverbs, 4 prepositions, 2 adjectives, 1 question word, 3 determiners, and 2 nouns. When I look at the fringe vocabulary we used “mail” and “package” I noted that these are words we use almost daily when debating who is going to get the mail from downstairs!
Of course this doesn’t include our conversations about Criminal Minds, Shemar Moore :), Marvel, Harry Potter, the school we work at, our friends, our favorite brunch places, etc. It’s so important to think about what fringe vocabulary is really important and meaningful for our students! Get to know them and make sure you’re customizing their devices to include their personal vocabulary 🙂
So when you’re thinking about vocabulary to teach your students, don’t choose core OR fringe. Choose both and plan a healthy balance. 🙂
