The article explores the experiences and attitudes of former developmental students in a manner that empowered and promoted the continued personal or educational shortcomings. It states that the study is focused on interrelationships such as the attribution of students on causal linkages between implementation of developmental mathematics and outcomes. Methodology-wise, the researcher used a single case design to contribute to theory building and knowledge. In connection, the implications for practices in developmental mathematics education directly related to the outcomes of the study are also discussed.

The article examines the role of mathematics in exploring the effects of over fishing on fish populations. It states that students first need to understand the basics of change and an example based on data from drive to work illustrates the basic ideas. The author then described a progression of population models that lead to a sophisticated model of the effects fishing can have on the population of a fish. In connection, the meaning of instantaneous rate of change or rate of change at a moment in time is also discussed in the article.
