Research on students’ perceptions and understanding of technology has shown that students have a narrow view of technology: for example, technology is often manifested in students’ descriptions as artefacts or objects. This paper aims at investigating how students develop understanding of how technology is manifested during classroom activities in technology. The study was conducted at a compulsory primary school with eight-year-old students.

The data (video and audio recordings) were collected in small-group interactions and whole-class discussions. In the interactions, the students utilised self-taken photographs to visualise their understanding and perception of technology. The analysing process is grounded in Mitcham’s (1994) manifestations of technology: object, activity, volition, and knowledge.

Based on the students’ prior knowledge, they perceived technology as contemporary electrical artefacts. The findings indicate that students achieve a more nuanced perception and understanding of technology as objects during classroom activities in technology.
