In this study, we provide insights about secondary school students’ conversation about products’ life cycles in relation to three dimensions of sustainable development: economic, social, and ecological sustainable development but also what traces of view that appear in these conversations. Production and consumption are part of complex technological systems that affect nature and life on earth, and knowledge about these systems are required to achieve sustainable development. In technology education, students can have the opportunity to talk about products and their life cycles. Hence, this study aims to explore what emerges in students’ conversations about products’ life cycles in relation to sustainable development. Data collection was conducted in Sweden through seven semi-structured interviews, with in total 21 students participating in groups. All student responses have been analysed using thematic analysis to explore dimensions and views of sustainability. Results show that the students discuss with regard to all three dimensions of sustainable development. However, the phases of a product’s life cycle occur to varying extent within the different sustainability dimensions. Additionally, the students also connect dimensions with both harmonious and contrasting perspectives but also talk about the dimensions isolated. When participating students discuss, traces of mainly anthropocentric and technocentric view emerge. This has implications for technology education, where for example deliberative conversations can be used for engaging students in sustainable development.

Learning to reason in the design process is enclosed in the process of learning to design. Hence, in this study, we explore teacher-student interactions with the aim of describing teachers’ support strategies in relation to enacted reasoning in the design process in secondary school technology education in Sweden. The study deploys social cultural theory as a lens, with a focus on scaffolding means and intentions of the teacher. Relevant reasoning in the design process is theoretically framed as means-end reasoning and cause-effect reasoning. Empirical data was collected through three classroom observations with three different Swedish secondary school technology teachers, with subsequent interviews with the teachers using stimulated recall. During the observations the students were engage in different design processes. The data was analysed using thematic analysis, where themes as strategies were constructed for each reasoning type from patterns of meaning in teachers’ scaffolding means and intentions. For each reasoning type, teachers employed strategies of decreasing control and increasing control. However, the enactment of these strategies differed in scaffolding intentions and means in relation to what reasoning was verbally enacted. Our findings indicate that teacher-student interactions within the design process in technology education classrooms hold significant meaning and value. This has implications for both teaching and learning in the field.
