ABSTRACT Background Despite the valuable learning opportunities experimentation offers, it poses significant challenges for teachers and learners. The effectiveness of instructional scaffolding in students’ experiments is intricately linked to science teachers’ conceptual foundations and practical abilities to impart science concepts and epistemic practices. Purpose Considering their metaphorical representations, this research unveiled science teachers’ imaginations regarding core epistemic practical work, specifically scientific experiments. Methods The present study engaged 340 Turkish science teachers. The participants used a metaphor imagination task to express their perceptions of scientific experiments. Results The study identified metaphorical conceptualizations organized around structural themes (action, tool, and place). This indicates that the participants perceived the generation of scientific knowledge through experiments as a dynamic process akin to science-as-activity. Furthermore, three predominant conceptual orientations were highlighted: hypothesis testing, knowledge production, and discovery. Teachers viewed scientific experiments as avenues for knowledge generation through discovery, with hypothesis testing playing a significant role. Conclusion The findings suggest that the metaphors conveyed a science-as-logic and science-as-theory perspective rather than a science-as-practice understanding. The study advocates for reconsidering and redesigning teacher training programs to instill the understanding that scientific experiments extend beyond isolated activities. These developmental programs should stress that experimenting is an epistemic activity involving collaborative knowledge generation within social, cultural, contextual, and institutional contexts.
