There are some key differences between humanities posters and science posters.
Science posters typically follow a very rigid format. They run three or four columns, to be read top to bottom, left to right. They also include (in this order) an abbreviated abstract, an intro section, a methods section, a results section (usually comprised of lots of tables and figures), and a discussion section (usually a bulleted list of several conclusions drawn from their findings).
Sometimes, reports in the social sciences and humanities will follow the same IMRaD (intro, methods, results and discussion) format.
However, sometimes our research in humanities and social sciences is not reported accordingly. When it is not, we have several strategies for organizing the narrative or exposition of our writing. We can follow the same flow of info (top-down, left-right) but organize our info around contextual themes or headings that organize our points.
a) The humanities can include visuals inspired from the imagery and illustrations in our text—topics, key terms or issues with pre-existing or readily available pictures. For example, in the second column of the poster below, the text mentions a web site, and a screen shot of the site is included.
b) The humanities can use a visual metaphor as backdrop for the text. For example, the poster below uses the reference to a “bridge” in the title of the report as a background image for the entire poster. The paper actually discusses strategies for people across disciplines to work together.
c) The humanities use remediation to organize the poster and render the expository argument visually. Bolter and Grusin (2006) invented the term remediation, which means taking an old medium and refashioning it as a new medium. In the example below, the poster remediates a popular board game to discuss the gamble and risks of starting a new academic program.
Your poster may include some of these elements!
