  This study evaluates the usage of virtual reality (VR) technologies as a
teaching tool in oral placement therapy, a subset of speech therapy. The
researcher distributed instructional videos using traditional lecture and
modified three-dimensional video to prompt responses. Data was gathered with a
two-part Google Form: In "Section 1: Knowledge Test" participants were asked to
determine how well they received the information displayed to them. In "Section
2: Opinion Test" participants were asked diagnostic and subjective questions
via Likert scale ranging from 1 ("Strongly Disagree") to 5 ("Strongly Agree")
to determine how well they enjoyed viewing the information displayed to them.
Averages for Section 1 were 92.00% for the control group (viewing 2D,
unmodified video) and 77.88% for the experimental group (viewing 3D, VR video).
Almost all participants answered at least 60% of the questions correctly.
Averages for 2D and 3D participants were 4.53/5 and 3.82/5, respectively for
"positive" prompts. Exactly 50% of participants experiencing VR video preferred
the method to a traditional lecture. This study determines that virtual reality
is viable as a learning tool, but knowledge obtained is not necessarily as high
as using traditional lecture. Further experimentation is required to determine
how well oral placement therapists respond to physically interacting with a
model instead of only viewing it. Copies of the Google Form used to collect
responses, all raw data, and a flowchart outlining each step used to construct
the 3D video can be found in the Appendix.
