Dynamic Assessment of Narratives: Which Language Should I Choose?

Dynamic assessment (DA) is a powerful approach that we can employ as part of diagnostic decision making. There are a number of advantages to DA, especially for children whose experiences don’t meet mainstream expectations including dual language learners. A number of DA approaches have been validated and show good sensitivity and specificity. DA of narratives and word learning are two of examples of these approaches.

Grammatical Assessment of Bilingual Children in English

We’ve had a paper out for a couple of years now and I’ve been meaning to blog about it, but for some reason other things have taken priority. The question that we addressed in this study is the extent to which English assessment of children who are Spanish-English bilinguals would be useful for identification of DLD.

Assessment of Bilinguals: Don’t Go NUTS!

For a long time, many of us have worked on development of better assessment methods for bilingual children. We know that many of the measures normed for monolinguals are not appropriate for bilinguals. We know that translated measures can lose their psychometric properties because difficulty may shift in translation. But, in the last 20 years there have been more measures and procedures that are validated for Spanish-English bilinguals. Work on other language pairs is emerging as well, but right now the majority of available measures focus on Spanish-English.

We Can’t WAIT!

There’s been a lot of discussion concerning COVID19 and schooling from home. In the special education domain, at least in speech-language pathology, we seem to be all over the place. Not that it’s easy it’s not. But, I hear a lot of comments and reports that school districts are suspending special education testing:

  • till schools open again
  • because standardized tests aren’t standardized for on-line administration
  • because we’re not comfortable
  • because we think that it can’t be valid

Why Opinion and Personal Observation isn’t as good as Systematic Research

Families of bilingual children with developmental language disorder (DLD) are often told to use only one language. School district personnel may insist that these children receive instruction in only one language even if there are bilingual programs available. Even bilingual personnel who work with children (teachers and SLPs for example) may say that children with DLD can become more confused if in a bilingual environment. This is simply not true. I have participated in many studies that demonstrate that bilingual children are not more likely to show higher risk for DLD than monolinguals; we know that bilingual children with DLD show comparable performance to monolingual children with DLD; we know that bilingual children with DLD show cognate advantages similar to typical bilinguals; we know that intervention in one language can carry over to the other language. This work is all supported by the data-based research (linked) and is consistent with work that other researchers are doing. Read the rest of this entry »

Testing in Two Languages

When we test bilingual children we need to be able to do so in both of their languages. We can to look at speech and language in each of their two languages and we use this information to determine if their language production is like that of their typical (bilingual peers).

In the area of lexical-semantics we know that children who have exposure to two languages often show patterns of lexical knowledge consistent with their divided exposure. They may know home words in the home language and school words in the second language. It makes it difficult to test in only one language, but how do we take account of both their languages?

One of the observations we’ve made in many years of testing bilingual kids is that it is difficult at times for them to switch between languages– especially when they’ve been using English in diagnostics. This doesn’t mean of course that kids don’t codeswitch, they do and they do so during testing, but switching between languages on demand is hard.

Cognate Advantage in DLD

Cognates are really interesting words that share meaning and sound the same across languages. Languages that share the same roots also have a large number of cognates because of their shared histories. Spanish and English share a large number of cognates.

We’ve studied cognate recognition in young children. In that study of kindergarten  and first grade children, we found that Spanish dominant children and English dominant children scored similarly on  a receptive vocabulary test given in English. But, they showed different patterns of response. Those who were Spanish dominant were more likely to know the cognates– even those that were above their age level. English dominant kids tended to know non-cognates. So, consistent with other studies, we found a cognate advantage for Spanish-speaking children learning English as a second language. In a recent study,  we were interested in whether bilingual children with DLD would show a similar cognate advantage. Read the rest of this entry »

Does conceptual scoring increase classification accuracy for vocabulary tests?

We’ve (as a field) have known for about 20 years that single word vocabulary tests whether they are receptive or expressive tests are poor indicators of developmental language disorders (DLD). At the same time, these tests are very often used by SLPs as part of a diagnostic. They are easy to give, quick, and highly reliable. It’s hard to make an error in  administration or scoring on these tests. But, reliability is not enough (neither are the other reasons). Even if it only takes 5 minutes and the score is a perfect representation of what the child can do it doesn’t mean that a low score indicates impairment or that a high score indicates typical development. As far as domains of language go– children with DLD do pretty well with vocabulary at the single word level. It’s semantics (connections among words) that they have difficulty with.

Stop Telling Parents of Bilingual Children to Use One Language

I keep hearing these stories and it’s infuriating! There’s no evidence that bilingualism is confusing and no evidence that bilingualism makes developmental language disorder worse so stop it! Read the rest of this entry »

Can we improve home language surveys?

I’m working on a paper that focuses on language dominance, proficiency and exposure. I’ve written about these definitions before. Here, I want to think about how it is we capture this information.

There are a number of really nice surveys and questionnaires that have been developed that help to document this information. These include L1 and L2 age of acquisition; educational history in each language, rating of proficiency in each language. Sometimes this is broken out into speaking, listening, reading and writing. Some questionnaires ask about what language is more proficient, and may ask for what purpose(s) each language is used. This information is designed to get at the question of how language is used and how proficient an individual might be across situations.  Read the rest of this entry »
