This paper builds on a previous study of the 'demonstration' as a signature pedagogy in design and technology (D&T). The demonstration is a fundamental pedagogical tool in practical subjects, for the development of learners' procedural knowledge, from observation and imitation to autonomy and adaption of a technique. As such, it tends to align itself at the restrictive end of an expansive-restrictive pedagogical continuum. In the preceding study, a dialogue emerged around the role of the teacher as a "competent management of the learning experience", including teachers' competency and clarity of subject knowledge. The findings of this study highlight two similar, yet distinct, perspectives of the teacher as an expert and the teacher as a facilitator. This study continues a developing professional conversation around the nature of the demonstration, exploring a snapshot of teacher educators' subjective beliefs and values. The responses of the participants to a set of 62 statements, representing a range of potential opinions and perspectives, were deployed and analysed using Q Methodology. The sample is purposive and comprised of D&T teacher educators based in England. The study draws parallels with direct instruction and demonstration, and concludes that there different approaches to and ways of viewing demonstration. In addition, further consideration of the expansive-restrictive continuum as a framework for planning and evaluating learning in D&T may support theorisation of the subject, inculcation of theory and research informed practice.The research question for this study is-'What do D&T teacher educators believe to be effective practice when demonstrating skills and knowledge?' This study continues to develop the dialogue, begun by McLain (2017) and McLain et al. (2015), around the subjective views on the 'demonstration' in D&T; focusing on teacher educators in England and building on the initial analysis of data discussed in McLain (2016McLain ( , 2017. McLain (2016McLain ( , 2017 demonstration was described as encompassing aspects of teacher modelling and explaining, often supported by questioning. Furthermore, 'demonstration' typically focuses on practical techniques and procedures, often (although not exclusively) with regard to making and tool use. The literature review in McLain (2017) presented central concepts from a largely constructivist perspective and this paper seeks to critique different perspectives. This literature review explores the concept of a signature pedagogy and expands the discussion around the role of the 'demonstration' in relation to so-called domains of learning. In addition, literature from cognitive science (cognitive load theory, direct instruction and social learning theory), which purport to challenge the constructivist perspective on learning, is explored and evaluated.
