The purpose of this study is to investigate an immersive virtual field trip (iVFT) on topic specific academic vocabulary for students with developmental language disorder (DLD). DLD is the most common childhood learning disorder with a prevalence of 7.4%(1) and occurs in the absence of a known biomedical condition (e.g., hearing loss, autism, stroke, intellectual disability). DLD affects a person's academic and social function due to difficulty with using and understanding language.(2,3) Approximately half of students with DLD have a deficit in vocabulary that persists through highschool.(4) Once children fall behind in their language and vocabulary development, it is very difficult to catch up generally resulting in a wider gap as they progress through their school years. This deficit can have cascading social, mental health, occupational and financial consequences.(5) There is preliminary evidence that a virtual reality experience such as an immersive virtual field trip (iVFT) was beneficial for facilitating vocabulary and comprehension in general education(6-8) and within targeted populations of students including second language learners(9) and those with learning differences (e.g., autism,(10) attention deficit hyperactivity,(11,12) and dyslexia(13). The term "immersive" refers to a state of heightened sensation when viewing a simulated environment that is superimposed onto a screen with embedded multisensory input (e.g., visual, auditory, proprioceptive).(14) The viewer looks through 3D goggles to block out the present environment resulting in a feeling of presence. These simulated experiences or destinations (e.g., space) are a type of VR referred to as an immersive virtual field trip (iVFT). To date, there is a lack of empirical evidence, explicitly targeting academic vocabulary growth for early grade school students with DLD. In addition, no study has reported on learning outcomes of students with DLD following a VR condition. Therefore, the primary study objective was to compare gains in academic vocabulary measures between a traditional book condition and an iVFT learning condition for young students with DLD.

Primary | Compare vocabulary gains between the book and iVFT conditions | Change in target vocabulary words from pre to post intervention between the control book condition and the iVFT learning condition. Four-topic specific omnibus vocabulary measures include:
Divergent Naming (expressive): "Tell me the names of as many [topic] as you can think of, as quickly as possible, in one minute." One point earned for each named word. Word Naming (expressive confrontational naming): State name of target image presented in isolation. One point earned for each correct response. Picture Identification (receptive): Identify target picture in field of ten. One point earned for each correct response. Word meaning recognition: Match the word with the written meaning. One point earned for each correct response. |
1 week: pretest, three 15-minute intervention sessions, posttest | |
Secondary | Vocabulary growth following an iVFT condition | To determine if an iVFT is effective for improving topic-specific vocabulary four omnibus vocabulary measures will be conducted pre-treatment and re-administered post-treatment.
