While recent advances in software have made it easier for applied researchers to build increasingly complex models of individual growth and change, conceptual connections among competing models are often poorly understood. The purpose of this paper is to offer a pedagogical approach to establishing connections between models of growth and models of change or difference, with particular emphasis on the latent difference score model. Beginning with simple models for two-wave change, we illustrate how to design and interpret bivariate latent change score models using public-access data and data from a five-year pre-kindergarten through grade-three longitudinal study of language and reading comprehension development in the United States. Recommendations for teaching longitudinal design and analysis will be provided.
