DQ1 The Elizabethan Poor Law of 1601 established a framework for defining poverty and helping those in need, and it also influenced the delivery of human services in colonial America. Using this framework as a guide, compare and contrast poverty from historical and contemporary perspectives. Because poverty is still a major social issue, what similarities exist between historical and contemporary poverty? How have issues related to poverty changed over the past 400 years?
DQ2 Compare and contrast any two theoretical models from the assigned readings. Analyze these theories by discussing the strengths and limitations of their applications. Discuss how the identified models can be applied to the same group or issue you explored in the Unit 1 discussion.
