Course Notes on Research Foundations, Issues, and Use

Introduction & Table of Contents http://crahd.phi.org/Notes/TOC.pdf


More and more I have come to the conclusion that the core of the scientific method is not

experimentation per se but rather the strategy connoted by the phrase "plausible rival hypotheses.”

Donald Campbell, foreword  to Yin’s (1989/2003) Case Study Research (see V2 below)


Scientific inquiry is a long and tortuous process, with many false starts and blind alleys.

Combining qualitative insights and quantitative analysis—and a healthy dose of skepticism—may

provide the most secure results.   –David Freedman (2008/2010) (see F12 below)


I began these course notes for the UCB School of Public Health DrPH 3rd Year Seminar I co-taught spring semester, 2005, and further developed them for our DrPH 1st, 2nd, and 3rd Year Seminars from 2005 through 2011, and then my Ford Foundation Research Fellows Health Issues Seminars from 2011 through 2014. They are still evolving. Most of the notes are just one or two pages, and many are excerpts from longer treatments in my own work, or the works of other authors.  


The aim of these notes is to provide clear and illuminating (hopefully) overviews of some of the knottier issues in research and research use that are essential to public health researchers and research consumers alike, yet commonly overlooked or misunderstood by students as well as experienced professionals. The probing discussions of these topics that I’ve been fortunate to engage in with numerous DrPH students, Ford fellows, and SPH faculty colleagues have been stimulating, rewarding, and immensely helpful in the development of these materials, and in the testing and deepening of my own knowledge and understanding.  Additional feedback is always welcome.
