“…The current study examined the chemistry textbook and experiment manual for the incorporation of EDP using modified rubrics based on the National Science Education Standards (NSES; National Research Council (NRC), 2012 ; NGSS, Lead States, 2013 ). The modifications were carried out using the same techniques as in related investigations ( Chiappetta and Fillman, 2007 ; Kahveci, 2010 ; Dunne et al, 2012 ; Mangold and Robinson, 2013 ; Vesterinen et al, 2013 ; Aldahmash et al, 2016 ; Aldahmash and Alamri, 2020 ; Aldahmash and Omar, 2021 ). The rubric for this study was designed using the eight NGSS practices ( NGSS, Lead States, 2013 ) and the additional redesign process ( Hirsch et al, 2017 ; see Table 1 ) included by us (henceforth the term EDP will include all nine practices):…”
