“…An example is the Mathematical Quality of Instruction (MQI) analysis framework (Mitchell and Marin 2015), which utilises aspects such as teacher mathematical error or imprecision, use of mathematics with pupils, cognitive demand of task and student work with mathematics. Roth McDuffie et al (2014) provided participants with 'four lenses of analysis of lessons' (namely, teaching, learning, task, and power and participation). The Lesson Analysis Framework draws attention to four aspects of the lesson and particularly to connections between them: the learning goal of the lesson, pupils' learning, specific and instructional activities and alternative strategies (Santagata et al 2007;Santagata and Angelici 2010;Santagata and Guarino 2011;Santagata and Yeh 2014;Yeh and Santagata 2014).…”
