What are some possible explanations for this distribution? Enduring Understanding: Health and disease are not distributed haphazardly in a population. There are patterns to their occurrence that can be identified through surveillance. Analysis of the patterns of health and disease distribution can provide clues for formulating hypotheses about possible causes. 1 New Lesson 1-8: Surveillance Studies – In School Revised Oct 22, 2011

Teacher Note: Enduring Epidemiological Understandings for the Epidemiology and the Energy Balance Equation Curriculum 2 New Lesson 1-8: Surveillance Studies – In School 1.Health and disease are not distributed haphazardly in a population. There are patterns to their occurrence that can be identified through surveillance. Analysis of the patterns of health and disease distribution can provide clues for formulating hypotheses about their possible causes. 2.Causal hypotheses can be tested by conducting investigations of the exposures and outcomes of selected groups of people as they go about their lives. Information from these observational studies can be used to determine if an exposure and an outcome are associated. Because observational studies are complicated by factors not controlled by the observer, other explanations also must be considered.

Teacher Note: Authentic Assessment for Module 1 of the Epidemiology and the Energy Balance Equation Curriculum Students will conduct and interpret a descriptive epidemiological survey among students in their class and again among students outside their class. Working in teams, students will have the opportunity to demonstrate their abilities to request informed consent, ask questions about a health-related behavior, accurately record responses, calculate prevalence of the behavior, make accurate statements about the prevalence of the behavior among their classmates, look for patterns, and formulate hypotheses based on the patterns they observe. Deliverables will include either written reports or presentations about the surveys. Specific performance criteria will be used to help ensure that the experiences allow a genuine, realistic, and fair assessment of students’ comprehension of the Module 1 Enduring Epidemiological Understanding. 3 New Lesson 1-8: Surveillance Studies – In School

6 Big Ideas in Lesson 1-7 The in-class surveillance study is the final practice for conducting a survey of other students in the school This is simulated research, not actual research, because the results are not generalizable Steps and materials should all be ready prior to starting. In all aspects of the survey, every effort should be made to protect the privacy of participants and their information The survey yields counts, that can be turned into prevalence rates, that can be turned into statements, tables, and/or bar graphs Survey results can help formulate hypotheses (educated guesses) to explain patterns of a health-related behavior Review New Lesson 1-8: Surveillance Studies – In School

Informed Consent Script I am about to give you a Question / Answer Form on which a question is written. Do not write your name on the form. I am going to ask you to answer the question by circling your answer with a No. 2 pencil and then immediately folding the form in half so that no one else can see your answer. You do not need to answer the question. If you do not wish to participate, simply fold the form in half. Your participation is voluntary, anonymous, and confidential. Let me repeat – You are not required to participate and nothing will happen to you if you do not. I will pass several large envelops around the class into which you can place your folded form regardless of whether or not you answered the question.
