The CHILDES study looks at parent-child interactions across American and Chinese samples. We evaluate teaching and learning behaviors between parent and child. The coding we use focuses on the type of teaching being used by parents and the associated child response. For instance, whether parents use declarative or procedural knowledge, and whether this elicits child agreement/mistake/follow-up and so on. For this research, we are using secondary data (pre-existing data) therefore the current aim for this project is to code and compare both data sets.
