In the assertion-evidence (AE) approach, you build your talk on messages (not topics) to tell a coherent and compelling story about your work. Those messages you then support  with visual evidence (not bullet lists). In addition, you engage the audience by fashioning sentences on the spot, but after practice.  The assertion-evidence approach is emerging in scientific presentations at a host of institutions: Penn State, MIT, Cornell, Rose-Hulman, Simula Research Laboratory, Air Force Institute of Technology, Texas Instruments, the University of Michigan, ​​the University of Wisconsin-Madison, and the Engineering Ambassadors Network. 

Build talks on messages,
not topics

Building your talks on messages, rather than
phrase ​topics (as most people do), will make your presentations more focused.

Support messages with
​visuals, not bullets

Most speakers project too many words, which overloads the audience. However, audiences can process visual evidence while listening. 

Explain visuals by forming sentences on the spot

​The best speakers fashion sentences on the spot, but do so after planning and practice. Delivering in this way projects much more confidence.
