Assess, reflect, and follow up.
The framework for public communication in chemistry is an iterative process. Plan time to assess, reflect on, and follow up on your event to improve your ability to develop future events that will be effective and meaningful for you and for participants. You might ask these questions: (1) Have I achieved my intended goals and outcomes? (2) How can I apply what I learned during my communication experience to the next time?
Your presentation on fertilizer use and impacts is over. You could ask yourself these questions: Did the evaluation sufficiently determine whether you achieved your goal of increasing awareness of the chemistry of fertilizers and their role in the home and agriculture? What happened during the presentation that might inform how it was received or how you might refine it going forward? For example, did participants ask questions that indicated they understood the chemical concepts? How did the demonstration go? Will you modify or eliminate it in the future? Do you have any indications of whether you were viewed as a trusted, neutral source of information? And finally, what did you gain from the event?
