Vocabulary Approach: How to Use Semantic Mapping & the Research Behind it

This is a guest blog post by Monica, a school-based SLP, is all about how to use semantic mapping & the research behind it!

Do you have students with word finding difficulties, but are not sure where to start?

Have you talked to  their parents and teachers and they really want their student or child to be able to expand on their  ideas, but they really struggle with vocabulary? Do you wish you could embed another vocabulary  intervention into your existing narrative therapy? Semantic mapping is here to make your life easier!  Stay with me for how to follow EBP decision making and to see if semantic mapping is a good fit for  your students and their families. We’ll end with some therapy ideas for your sessions.  

Thorneburg et al. (200)Semantic Mapping

What is semantic mapping and how do you do it?

Semantic mapping is also called semantic feature analysis. We all know the term from grad school as a common form of therapy for aphasia. Semantic  mapping is when you list out features related to a word. It is most commonly done using  interconnected circles and charts. Using this strategy helps students/clients map out how words  are related to each other and develop a deeper understanding beyond labeling (Alt et al 2004).  Semantic mapping can include any words related to the target word to expand on knowledge about  the target word. Examples of ways to expand on a word are: categories, physical attributes, actions,  origin, emotions, and background knowledge. 

Let’s get to the research first.  

Semantic mapping has a lot of different names. In the research it goes by semantic mapping and  semantic feature analysis. We all know it from grad school because it’s a commonly used therapy  approach for aphasia. What does the research look like for the preschool to adolescent  population?  


Alt M, Plante E, Creusere M. Semantic features in fast-mapping: performance of preschoolers with specific language impairment versus preschoolers with normal language. J Speech Lang Hear Res. 2004 Apr;47(2):407-20. doi: 10.1044/1092-4388(2004/033). PMID: 15157140. 

Preschool research for semantic mapping isn’t as easy to find. The research that is  available points to SLI students having a more difficult time with semantic mapping than  their peers. 

The researchers suggested that these students are not just having a hard time labeling, but a deeper understanding of vocabulary

Preschool students with SLI in this study had a more difficult time with actions than nouns.

Intervention for children with word-finding difficulties: a parallel group randomised control trial. Int J Speech Lang Pathol. 2018 Dec;20(7):708-719. doi: 10.1080/17549507.2017.1348541. Epub 2017 Jul 31. PMID: 28756691. 

“Combining semantic intervention with phonological intervention led to on  average 4x growth in the experimental group than the control group”  Best et al. 2018

A randomized control study looked at word finding therapy for children with language  difficulties in a school setting.  

Treatment was done once a week for six weeks individually.  

Note: The children in this study scored within the normal range for comprehension and  did not have a diagnosis of dyspraxia, autism spectrum disorder, ADHD, or global delay.

Meta analysis research for the adolescent population showed mixed  results, but higher efficacy when using a phonological-semantic approach, with “outcomes that are better when the intervention is embedded in a wider language context such as a narrative approach”.

Overall, it looks like the research supports using semantic mapping when used  hand in hand with phonological mapping. Embedding semantic-phonological  mapping into a narrative approach may also improve outcomes. 

Client/Student & Family Values 

What are some things we can think about after we’ve selected a therapy approach to use?

Let’s  look at how to incorporate the client/client’s family’s factors like values and  cultural/socioeconomic factors. Consider the research when making a recommendation about  service delivery to the family and making a team decision.

“Students who received services through a collaborative model had higher scores on curricular vocabulary tests than did students who received services through a classroom based or pull out model. Although all three services delivery models were effective for teaching vocabulary.” Thorneburg et al. (200)

Clinical judgement and expertise 

After you have decided that it is appropriate for your client and the client/family agrees that it is  the best approach (maybe at an IEP meeting?), it’s time to use clinical judgement and expertise  to think of the ways to best use this approach in therapy. Hang on tight, right after this we’ll go  over some therapy ideas!  

Lowe et al. (2018) said that combining this approach with a phonological one, and  incorporating it in a narrative intervention has the most evidence behind it. Do you have  students that would benefit from this approach? Semantic mapping lends itself to using a  lot of visuals and easy to adapt to different learning styles and support needs.  

Set up a way to take baseline data and monitor progress (keep in touch with  teacher/caregivers to see if it’s working).  

We love working on areas that can give you more bang for your buck and have areas of overlap.

How is working on expanding vocabulary and strengthening this skill going to increase  access to the curriculum and participation in the classroom for this student? 

Will working on vocabulary and expanding those skills also help with socio-emotional skills  for your student/client? Would this help conversational skills and general functional  communication?  

Last Stop: Therapy Ideas

Use your existing narrative lesson

Incorporate semantic mapping by doing a book walk and map out new words before you start reading the book. You can also stop on ages to describe objects, characters, and setting using semantic mapping (ex: what they look like, how they feel, and what they’re doing).

Make it functional

Pick places on their school campus or from home. Add sentence frames for extra support. Ask caregivers for ideas of things that they have a difficult time expanding on or things that they frequently have a hard time naming.


Work with teachers to do phonological-semantic mapping for upcoming themes and activities to increase participation in class. This would be a great time to incorporate actions as target items.

Use high interest targets

Introduce new adjectives to talk about high interest shows or movie clips to expand language. 

Make a story with new words

Make a narrative or story using new words that you have targeted to increase word exposure. The more exposures to a new word, the better!

Don’t forget to use phonological mapping

Spell out the work and sound it out to include phonological mapping to help students learn the word. You can clap out the syllables, include a word that rhymes, or other words that start with the same sound. 

But how do I know if it’s working?

Last but not least! Don’t forget to take the time to review if this approach is working by  comparing it to that baseline data that you took. Best et al. (2018) showed that 6 weeks of intervention was needed to show a positive effect for vocabulary intervention.
