“…Despite of the modifications, LS supports TCs’ learning about variation theory and applying it in their teaching in order to better facilitate students’ learning (Lai and Lo-Fu, 2013), improve instructional skills (Cheng, 2014), and develop their theoretical lens in/through teaching practice (Tan et al , 2019). More recently, Durden (2018) suggested that TCs could embrace LS as a valuable process to enhance their own conceptual understanding, improve lesson and attend to students’ differences. Due to its evidence-based lesson analysis, conscious reflection and reviewing of lesson, LS has been associated with TCs’ improvements in analysing students’ difficulties and conceptions, and planning lessons that meet curriculum requirements and students’ needs (Lai and Lo-Fu, 2013).…”
