Ecology has been a part in current education. Hence it has become gentle evidence that the instillation of ecological values has been carried out extensively and thoroughly to students. One of the ecological promotion media is through textbooks. The purpose of this study is to present an analysis of ecological content on reading materials and instructions on Skillful Reading and Writing books. Reading materials and instructions are on the analysis from the aspects of appreciation of nature, realistic ecological problems, positive tone, appropriate illustrations, and hope for a solution. This study belongs to qualitative descriptive research with document study data collection techniques. The content analysis results revealed - at least - half of all readings in the book treat the natural environment. Of the five ecological aspects, they could be sorted according to the degree of conformity, namely positive tone (5.0), appreciation of nature (5.0), realistic ecological problems (3.0), appropriate illustrations (3.0), and hope for a solution (2.0). However, not all those selected readings are supplemented with learning instructions leading to real actions to preserve and appreciate environments. Therefore, teachers should make purposively instructional adjustment to students’ conservation practices.
