Executive Summary
Children's accomplishments in elementary and secondary science classrooms
vary depending on their interest and experience with science topics. More
troubling is the fact that science achievement also varies predictably
depending on other factors, such as children's gender, native language,
parent's education background, and socioeconomic level. Many researchers
and educational advocates are interested in how these predictable variations
can be overcome through early experiences with science. At the same time,
researchers have been learning a great deal about how very early childhood
is a time of exploration of the world in which children develop early
understandings of certain concepts that can be linked to later science
learning. This project focused on young children's "science talk," including
causal questions and explanations in conversations with parents and teachers.
There were two basic sets of research questions that were addressed in
this work:
(1) What does "science talk" look like in everyday conversations in Mexican
descent families? Do these conversations differ (e.g., in frequency of
children's questions, frequency of parents' explanations, content of parents'
explanations) depending on the educational background of the parents?
(2) What does "science talk" look like in preschool and early elementary
classrooms? If teachers know more about the characteristics of science
talk in family, how might they make use of this information as a "fund
of knowledge" regarding children's ideas, interests, and understanding
of particular topics?
The research design used in these studies was a combination of videotaped
interactions (both naturalistic observation and more structured activities),
diary reports from parents, and interviews with parents and teachers.
The videotaped data, which make up the bulk of the work, were collected
in several different settings: family homes, children's museum and aquarium
settings, preschool classrooms, and elementary school family science workshops.
In these studies, the data were conversations about museum exhibits and
science topics, and the unit of analysis usually consisted of questions
and explanations that came up in the conversations. We coded questions
and explanations in terms of their content, as well as the function they
served in the conversations. All coding schemes were developed, revised,
and tested for inter-coder reliability.
Overall, the findings showed that parents and children engaged in many
conversations about scientific topics, and that this was true regardless
of the educational background of the parents. There were some suggestions
that explanatory conversations were more frequent in families where parents
had more formal education, but this was only true in some activity settings,
and it seemed to be mediated by the goals of the parents in the activity.
In general, everyday conversation is a place where children and their
parents puzzle at times over various events and ideas that they encounter
as they go about the routines of their lives. At times, these conversations
focus on topics that are relevant to science. The ways that parents communicate
what they know and model figuring out what they don't know may give children
important information about the world and how to understand it.
There are important implications of these findings for current educational
practice. First, teachers must be made aware of how widespread these informal
science conversations are in children's everyday activities. Building
on this foundation can help teachers to connect with children in more
meaningful ways. Individual children's interests and questions are known
by their families far better than by their teachers. Finding ways to forge
links between home and school has been a goal of many educational researchers.
Our initial attempt to make such a link through informing teachers of
children's questions shows promise. It is, of course, more challenging
to find ways to make these links without the presence of a researcher
as mediator. We are hopeful that these findings may encourage teachers
to be creative about finding and supporting links with parents that are
bidirectional parents as experts on their children's learning can
be a great resource to teachers.
