Science communication has more than one definition, but I tend to think of it as falling into one of two categories: the science of science communication, and the practice of science communication.
The science of science communication is a social science research discipline. For example, the journal Science Communication, publishes research related to “the nature of expertise, the diffusion of knowledge, and the communication of science and technology among professionals and to the public.”
That covers a lot of ground.
I view the practice of science communication as an equally broad category, encompassing science journalism, blogging, social media, videos, art, academic publishing, and any other activity that aims to help people understand anything related to research findings or the scientific process.
This blog is primarily focused on the practice of science communication, though I do often write about science communication research – particularly in regard to how it might inform practice.
