“…In the period of DESD followed by GAP, many countries put efforts to increase the quality of education in national and regional level and previous studies may provide insight for the analysis of Secondary Science Chemistry Curriculum. Literature research for this study show that there are studies on ESD in primary education (Summers & Kruger, 2003;Tanrıverdi, 2009;Kadji-Beltran, et al, 2017), secondary education (Berglund, Gericke, & Chang Rundgen, 2014;Jegstad & Sinnes, 2015;Firth & Winter, 2007), higher education (Ryan & Tilbury, 2013;Sterling & Scott, 2008) There are certain differences encountered by teachers based on the subject area of the course (Borg, Gericke, Hoglund, & Bergman, 2012), yet the framework must have a sound basis for the specific course handled. Therefore, imposed frameworks, curricula and teaching activities should address specific needs and barriers of the discipline under investigation (Borg, Gericke, Hoglund, & Bergman, 2012).…”
