1.3. Book reading and Play Intervention Procedure
Book reading and play sessions were conducted by a trained individual referred to as an Intervention Specialist(IS),who was different from the children’s classroom teachers and from the individuals
who administered the pre - and post-tests.The ISs were individuals with some experience with children and/or a background in early childhood education(e.g.,former preschool teachers,children’s
librarians, students in the process of earning their teaching certificates). They were recruited from the
areas in which the participating schools were located.During a two-day training session before the
start of the intervention,all ISs learned about the intervention method and practiced delivering the
book reading and play scripts.They were observed during these practices by a member of there search
team and were corrected as necessary to ensure that they maintained fidelity to the scripts.
Each IS carried out the intervention with groups of three children.With in each classroom,children
were randomly assigned to groups,without regard for friendship or gender,though we attempted to
construct groups that were mixed-gender when ever possible.These groups remained the same over
the course of the intervention,and the same IS worked with that group through out the intervention.
The first week of the intervention involved reading one book to the group of three children for four
consecutive days.The following week,the IS read a second book on the same theme to the group.
On each of the 8 days of the intervention,one intervention group of three children was taken out of
the classroom to a quiet area to listen to the book and play with the toys.Each day’s book reading
took about 10 minutes and was followed by a 10-minute play session with replica toys that matched
the characters and other prop smentionedin the story.IS supported the children’s play by using the
provided scripts, as described above.
Each IS was assessed for fidelity of delivery of the intervention by having a member of the research
team observe three of her session sand note any deviations from the book reading or play script (e.g.,
missed definitions) .All IS sweredeemed to be delivering the intervention with in appropriate parameters less than 10% deviation per session Informal observation of the intervention sessions,both
during the seass essment sand viaare view of asub set of the recordings, indicated that children were
highly engaged in both the book reading and the play sessions for both themes.
Across classrooms,we counter balanced the theme of the book sand play materials, as well which
of the two books from the them ewasread first.
