Textual analysis is a commonly-used qualitative method for analysing and interpreting cultural texts. This approach elicits how representations occur, their underlying assumptions and how they come to have meaning. Despite the popularity and utility of textual analysis, its interpretive and theoretical strategies are not comprehensively described in science communication research. To fill this gap and clarify how textual analysis can be used to unpack the cultural meanings and representation of science in visual texts — images, comics and films — the authors analyse and discuss four environmentally-themed scholarly articles that apply textual analysis. This showcases the value of textual analysis in investigating and understanding the relationships between pop culture and science, demystifying it for science communication students and researchers.
