This study aims to identify environmental values in second-generation textbooks and to identify the most important environmental behaviors included in them, thus contributing to strengthening these values among primary school students. This study is conducted based on the content analysis of second-generation civic education textbooks, all levels combined (from first year to fifth year). A content analysis approach was adopted and the study resulted in several observations, including: the environmental behaviors included in primary school civic education textbooks are divided into four basic environmental values: environmental preservation, environmental exploitation, environmental aesthetics, and cleanliness and public health. These values are at the top of the environmental values included in civic education textbooks. The environmental behaviors included in the civic education textbook reinforce environmental values among learners, thanks to the sequential and coherent nature of the cognitive content and its compatibility with the learner's developmental stages.
