Penn State Engineering: A Leader in Scientific Communication

Imagine yourself in this situation: you go to a presentation (at work, in a class, at a conference) and you’re determined to learn something new. You’re with the speaker at the beginning—he (or she) introduces himself and mentions his affiliation. Maybe you even understand the title of his talk. So far, so good. Then, before you can even prepare yourself, he launches into the core of his talk, complete with full paragraphs on his slide (of which he reads every word), charts with axes at size 2 font, out-of-control laser pointing, acronyms you don’t understand… And you start thinking about all of the less painful things you could be doing with your time. Death by PowerPoint—we’ve all been there.

Penn State professors Michael Alley and Melissa Marshall are actively changing the stereotype that engineers and scientists are poor communicators. Termed the “Assertion-Evidence Approach,” their advocated slide design employs the use of two simple concepts. On each slide of a presentation, determine the most important message (which is a full sentence) of that slide and put it at the top, where the audience can readily see it.  Then, support that assertion with visual evidence.  Professors Alley and Marshall regularly travel worldwide giving lectures and communications workshops, and are sought out by both industry and academia alike.  At Penn State, they devote their time to training their students, ensuring that their legacy carries on.  Their students develop as confident speakers and, as they transition into their roles beyond Penn State, continue to spread the Assertion-Evidence message.

A revolution in scientific communication is coming and it has its roots in Penn State.  As the Assertion-Evidence technique spreads, the important messages from our scientists and engineers impact a continually widening audience. The benefits of strong scientific communication never end; one day, perhaps even in the near future, poor presentations will be in the strong minority and we can all be prepared to learn about the new, exciting, innovative developments our scientists and engineers make every day.

Katie Kirsch is a Ph.D. student in the Experimental and Computational Convection Laboratory (ExCCL) at Penn State. Her research focus is on the cooling of turbine vanes and blades in gas turbine engines. She has also conducted research in the area of gas turbine heat transfer at the Karlsruhe Institute of Technology in Karlsruhe, Germany. Additionally, she is involved with the Engineering Ambassador Alumni Association and the Women in Engineering Affiliated Program Group. 

Katie graduated from Penn State with a B.S. in mechanical engineering and a minor in engineering leadership development in 2011 and an M.S. in mechanical engineering in 2013.
