A 2012 SENCER Model
Public Understanding of Science is an interactive course that aims to train students to communicate science to the public in an understandable and inviting fashion. We aim to combine the increase of the students’ love for science with an increase in their sense of duty to bring science to the public. Thus, our approach is two fold: to train the students to communicate science, and to generate opportunities for the students to actually practice their newly acquired skills.
The course has a significant interdisciplinary component, through the choice of topics, the interaction with faculty mentors from different disciplines, and the fact that the class consists of students from different departments. More importantly, in demonstrating how basic science results in tangible advances to our daily lives, the students have to explore a topic from many different science disciplines. For example, we owe our ability to undergo corrective eye surgery to physicist who studies lenses, physicists who studies laser, anatomists, neurobiologists, physicians who studies the eye and the eye/brain interaction and so on. By bringing these topics to the public the students increase the public’s understanding of the nature of and need for basic science. Moreover, it develops in the students a sense of civic engagement, and a responsibility that we believe all scientists should share: to explain to the public the importance of science in our society. In the past several years, students generated 35 different presentations, and have given over 110 presentations to adult audiences in the community.
Linking Science and Social Issues
See Table 1 in “Science and Me: A Student-Driven Science Outreach Program for Lay Adult Audiences” for examples of civic questions and relationship to science content.
Science and Me
Below is list of student presentation topics:
MU – Fall 2008
It’s getting hot in here: What’s the big deal about climate change?
Katie Becklin, Division of Biological Science
There’s a lot of talk about global climate change, but what does that term really mean? Come learn the science behind climate change and how this phenomenon might affect you, your health, and your interests.
The aging brain: What to Remember about Memory Loss
Catharine Clark, Biomedical Sciences
Do you ever feel like you just can’t remember things the way you used to, or you occasionally have to “jog your memory” to come up with names and places? Don’t worry you are not alone. This presentation will explore the intricacies of the brain, how memory loss occurs and more importantly how to have more control over the aging brain.
Land-use effects on biodiversity: How can my golf game help frogs and salamanders?

Everybody likes having a nice looking yard, but what do we do about animals wreaking havoc on our plants? What causes this problem? What can we do to deal with all those critters?
The ever changing Flu virus and elephants with short tusks – what do they have in common? Why is it so hard to guess the correct flu vaccine?
Kathy Klymus Division of Biological Sciences
How can changes in an environment lead to changes in an organism’s traits? We will look at examples from creatures as diverse as viruses and elephants to explore this idea of natural selection. We will learn how natural selection affects us with respect to vaccine- resistant diseases.
Genetically modified food: What’s on your dinner plate?
Amy Replogle Plant Science

So how do you know if you are eating genetically modified food? Well the truth is you can’t so this talk will address what are genetically modified foods and what you should know about them.
The eye, the light and the lens: Why is it getting harder to see as I get older?
Andrew West, Science Education
Is it getting harder and harder to see? Are eye appointments and the explanations that the doctor gives sometimes unclear? We will explore how the eye works, why it is sometimes difficult to see, and what the eye doctor does to help us see better.
Infectious diseases: Can I catch my dog’s cold or the bird’s Flu?
Jordan Shroyer, Fisheries and Wildlife
Should we really be worried about catching the “Bird Flu”? Are we really capable of catching another animals’ illness? Spreading of disease and possible outbreaks will be discussed.
MU – Fall 2009
Development and Cancer – When the body does not play by the rules..
Anthea Aikins, Molecular Microbiology and Immunology
There are certain rules that control our body to make it function successfully. Compromising these rules can lead to diseases such as cancer. Join us as we explore the essential rules in the body and what happens when the body does not play by the rules.
The Secrets Behind the Sound of Music – Science, symphonies, and synthesizers
Gina Applebee, Geological Sciences

Obesity, Diabetes, and Sleep Loss: Do we “gain” by losing sleep?
Rachel Barker, Geological Sciences
Sleep is necessary to maintain good health, but studies show that people are not getting enough. When we lose sleep we risk more than simply feeling tired. Could this epidemic of sleep loss be a contributing factor to some of the other health issues we see today?
My family’s genes – Do I have to be a chip off the old block?
Erin Flenner, Division of Biological Sciences

Think Green – Having your medicine and eating it too?
Tiffany Langewisch, Division of Biological Sciences
Even though illness has been around for centuries, doctors could not prevent sickness until the development of the smallpox vaccine. Today, biotechnology provides an alternative to traditional injection-based vaccines. How can eating produce help protect you against disease?

The geologic timescale – Where do we fit in?
Geneviève Robert, Geological Sciences
The Earth is nearly 4.6 billion years old and has gone through many exciting transformations, from Moon formation early in its history to the beginnings of life more recently. How exactly is the history of the Earth defined? Where do we, humans, fit in? And why it is important?

Public Understanding of Science-Syllabus
Graduate students who take the course come from various different academic departments and have widely different scientific backgrounds. At the first meeting, students choose their topics and begin to investigate the material and prepare the presentation. A list of suggested topics for presentations is provided, but the students are encouraged to suggest their own topics on the basis of their passion and expertise, as long as they are not directly part of their graduate thesis research (see Table 1). University faculty members, experts in the latest scientific research in the related fields, are asked to mentor the students, both for accuracy of the presentation as well as for guidance in preparing and delivering the presentations. This has proven to be crucial to the preparation of the presentations and the success of the program. Organizationally, the course is divided into three parts: Part 1 (weeks 1–4) is devoted to choosing topics and mentors, building the presentations, and holding class discussions on related issues; Part 2 (weeks 5–10) is devoted to delivering the presentations to the class and analyzing their effectiveness; and Part 3 (weeks 11–15) is devoted to delivering the presentations to audiences in their venues and analyzing the experience to improve the presentations.
This course was not initiated as a controlled study of the public’s understanding of science. With two
years of success behind us, we are now designing careful pre- and postsurveys that will enable us to give a quantitative, statistically significant evaluation of the impact of the course. As of now, we rely on students’ presentation reports, students’ end-of-course evaluations, and responses from audience members and activity coordinators.

Science and Me
Student responses show that both students and audience members have benefited from the course and recommend the program to others.
