Science Teachers’ Pedagogical Scientific Language Knowledge—A Systematic Review

Since students’ knowledge of scientific language can be one of the main difficulties when learning science, teachers must have adequate knowledge of scientific language as well as the teaching and learning of it. Currently, little is known about teachers’ practices and, thus, teachers’ knowledge of scientific language, in general, and the teaching and learning of it (Pedagogical Scientific Language Knowledge, PSLK) in particular. For this reason, with this systematic review, we seek to identify elements of pre- and in-service primary and secondary science teachers’ PSLK. The search was conducted on the database Education Resources Information Center (ERIC) and resulted in 35 articles with empirical evidence after the selection process. The results have been deductively and inductively categorized following the framework of the Refined Consensus Model of Pedagogical Content Knowledge, elaborating elements of different knowledge categories that shape PSLK, as well as PSLK itself (e.g., knowledge of (i) scientific language role models, (ii) making scientific terms and language explicit, (iii) providing a discursive classroom, and (iv) providing multiple representations and resources). We can conclude that more research on PSLK is needed as analyzed articles are mainly based on case studies. Additionally, this paper shows a need for a stronger focus on scientific language in teacher education programs. Implications for further research and teacher education are discussed.
