Studies Found: Simple Dialogic Reading Technique Substantially Improved
Children's Vocabulary Development
¡@¡@Researchers at The Chinese University of Hong Kong have demonstrated
that just an hour's worth of training for parents on how to read
effectively with their children boosted their children's vocabulary
skills substantially over a relatively short time of several weeks.
In three separate studies of Hong Kong Chinese kindergartners, parents
who were trained to read to their children using the dialogic reading
technique, originally developed by Professor Grover Whitehurst in
the U.S., significantly improved their children's vocabulary knowledge
over time as compared to children reading with their parents the
way they typically did at home or not reading at all.
¡@¡@Dialogic
reading involves encouraging children to interact with storybooks
in a very active way. Parents ask children different types of questions
that require children to elaborate on the text and express their
ideas about the story freely. Ideally, the child becomes the storyteller,
and the parent becomes the facilitator and cheerleader for the child's
ideas about the story.
¡@¡@These
studies are part of on-going research on early language and literacy
development in Hong Kong conducted by Professor Catherine McBride-Chang,
M.Phil. student Bonnie Wing-Yin Chow, and Professor Him Cheung,
in the Centre for Developmental Psychology at The Chinese University
of Hong Kong. The first study showed promising effects of dialogic
reading for both vocabulary knowledge and literacy skill among 86
Chinese kindergartners after just two twenty-minute sessions per
week across eight weeks of parent-child reading. The second study,
perhaps the first of its kind in the world, demonstrated that vocabulary
knowledge of 28 hard-of-hearing children in their last year of kindergarten,
first, and second grades, improved substantially among families
using a combination of the dialogic reading technique and visual
aids. The dialogic reading technique is especially useful for promoting
communication in families with hearing-impaired children, and this
communication resulted in increased vocabulary skills over just
eight weeks. Both of these research studies have since been published
in academic journals.
¡@¡@The
third study, supported by the Quality Education Fund, involved 110
kindergarteners and their parents. Like the other two studies, this
study compared groups of families randomly assigned to one of three
conditions. One group was given no reading instruction and no extra
books. Children in this group were initially tested on reading-related
interest and skills and were subsequently tested twelve weeks later.
The second group was given a new book to read every week, and families
were asked to read the new book with their children the way they
normally would. In the third group, the dialogic reading group,
parents were initially trained on dialogic reading for one hour.
They were asked to use the dialogic reading technique in reading
to their children the new books they received each week. Results
of this study demonstrated that, compared to the first two groups,
the dialogic reading group improved substantially more on vocabulary
knowledge over the twelve weeks. In addition, only the children
from the dialogic reading group showed a statistically significant
increase in enthusiasm for reading, as measured by a questionnaire
about enjoyment of reading, over the twelve weeks. Parents' reactions
to the dialogic reading program were also strong. For example, 65%
of parents using this technique thought their children's interest
in reading had increased, while over 70% of parents thought their
children's vocabulary knowledge, verbal fluency, and Chinese character
recognition had improved as a result of this technique.
¡@¡@Overall,
this series of studies has demonstrated that the dialogic reading
technique can be easily applied to Chinese language and literacy
learning, with clearly positive, measurable results in 8-12 weeks.
In addition, the results of the study with hearing-impaired children
are particularly encouraging, because language-learning, especially
vocabulary development, is notoriously difficult for hearing-impaired
children. The technique is easy to learn and apply. The goal of
the technique is to get children to talk about the stories they
read and for parents to encourage this discussion and expand on
their children's comments. More information on specific techniques
for dialogic reading can be found on the dialogic reading website

The
dialogical reading has worked well in promoting early language and
pre-literacy skills in children learning to read in their first
language.
