“…It has been extensively studied over the decades from multiple perspectives, including cognitive orientation ( Borg, 2003 , 2006 , 2009 , 2011 ), sociocultural theory (SCT) ( Johnson, 1994 , 2009 ), reflective practices ( Farrell, 2013 ), and complex dynamic systems theory ( Zheng, 2015 ; Gao, 2021a ). It has also been studied from methodological approaches (e.g., Kalaja and Barcelos, 2003 ; Borg, 2012 ), review or historical analysis (e.g., Gao, 2014 ; Fives et al, 2019 ), and tensions between beliefs and practice ( Borg, 2018 ; Gao and Bintz, 2019 ; Gao, 2021a ). Mapping out the existing literature on teacher beliefs over the decades, Gao (2021a) explained that teacher beliefs are in nature complex, non-linear, and unpredictable and may include different theoretical orientations of teachers’ subject matter, matrixing in different forms to inform teachers of their practices.…”
