This Assignment measures your ability to locate scholarly sources and outline research methods used in child and adolescent development literature. There are many research designs that are used in developmental research. As discussed in your textbook, longitudinal, cross-sectional, and sequential designs are used to assess developmental change and to explore developmental topics and changes over time. Empirical research (research based on actual observation or experimentation) that uses such designs is usually found in scholarly or peer-reviewed journals. The articles in a peer-reviewed journal have been sent to a panel of experts in the field for review and assessment.
