A new study by the UNESCO Global Education Monitoring (GEM) Report shows how secondary school textbooks from the 1950s until 2011 missed or misrepresented key priorities now shown as crucial to achieve sustainable development. With textbooks only revised every 5-10 years, the analysis reveals the need for governments to urgently reassess their textbooks to ensure that they reflect core values for sustainable development, including human rights, gender equality, environmental concern, global citizenship and peace and conflict resolution.

Released around International Day of Human Rights, the analysis looked at secondary school textbooks in history, civics, social studies and geography. The materials were drawn from the Georg Eckert Institute in Germany, which holds the most extensive collection of textbooks from around the world in these subjects.
