Abstract
Background: This study explored how Saudi Arabian pre-service science teachers' (PST) use of social media (SM) creates scientific dialogue.Design and method: Data were collected via (a) in-depth interviews with eight science PSTs completing their practice teaching during a field experience course (2017 academic year at a Saudi Arabia Eastern province university), (b) focus groups with 21 female science students being taught by the PSTs, and (c) an analysis of SM artifacts (i.e. PST's students' Tweets and Snapchat comments about their SM-based science homework).Results: Findings from content analyses indicate that the PSTs overwhelmingly perceived SM-based science teaching as providing their students with opportunities to pose critical questions, improve science learning, and engage in scientific dialogue and argumentation. Students welcomed the SM-based science learning, saying it excited them, made them want to learn science and helped with collaborative science learning. The majority (87%) of PST's students expressed an interest in using SM to engage with science concepts. Also, findings affirmed that social media serve as mediating agents for reaching students in their learning Zone of Proximal Development; that is, SM-scaffolded science learning. The findings are considered in terms of further pre-service science teacher education and Saudi-based educational research.
