Nested hierarchical structure is one of life's most familiar properties and a major component of biological diversity and complexity. However, there is little effort to teach the evolution of the hierarchy of life, as there is little effort to teach biological complexity per se. We propose a framework for teaching biological complexity based on…

This chapter focuses on how researchers and practitioners negotiate the focus of their joint work within design-based implementation research (DBIR). Studying and facilitating successful negotiation of the problems that become the focus of work and the search for solutions is important for developing DBIR, because of its commitment to focusing on…

"Chaos" theory is a revolutionary new paradigm developed by scientists to study the behavior of natural systems. "Chaos" refers to the tendency of dynamic non-linear systems toward irregular, sometimes unpredictable, yet deterministic behavior. Major tenets of the theory are presented. The precedent for use of models developed…

A study examining small group performance replicated and extended a previous study by L. Kelly and R. L. Duran to reanalyze their operationalization of cohesiveness. To test the hypotheses of the original study and to explore questions about using the polarization index as an indication of group cohesiveness, the study used a large number of…

A study of the English of British schoolchildren of South Asian extraction looks at ways of examining the relationship between their English and two ethnic processes, called "interactive" and "reactive". The way in which Network Analysis permits investigation of the interactive process is outlined, and the use of Identity…
