Systems Thinking in Public Health is an online course offered by Johns Hopkins University. This 4-week long course introduces systems thinking and systems models that are used in public health and why systems thinking is a core skill to help policy makers build programs and develop policies. The importance of integrating multiple perspectives and synthesizing them into a framework or model that can describe the ways a system might react to policy changes will also be discussed. In addition, the course will introduce the concepts of systems dynamics modeling by using the software Vensim to practice running simple models. The time commitment for this course is 4 to 5 hours a week working towards completing all course materials. Each week is taught using a series of videos and readings, in addition to weekly quizzes aimed at assessing the individual’s knowledge of the subject. Those who pass all graded assignments will complete the course.
