Since the industrial revolution, awareness of severe threats to the global environment has risen. Nature Conservation is an important link in education, so the researcher utilized Nature Conservation books as the topic for Environment Education Teaching in school.Reading is the main foundation of learning. Students can improve their expression, comprehension, and thinking ability through reading and discussion. In addition, students can acquire some experience of life by recognizing, imitating and playing the roles in books. Thus, reading and discussion are very good methods for Environment Education Teaching.This research shows how to integrate Nature Conservation into reading classes in schools with the cooperation of teachers by means of action research. The subjects are grade five elementary school students in Changhua. They are taught by a literature discussion program and use six children’s books about Nature Conservation as teaching materials. For discussion, they are grouped by ”Phillips”- six pupils in a group, one minute for each, and share what he/she has learned in six minutes. Pupils in a group discuss first; then the whole class has a debate and further activities are performed. During the teaching process, the teaching mode is improved and the revised teaching mode is put into practice in the second class for the spirit of action research.During the whole teaching period, the researcher collects students’ study continuously, reads the reading notes, draft word-for-word of interviews, analyzes the reading notes and noting down and examining cores to confirm each other in coordination with the teacher’s observation of the researcher, complement and measure the teaching achievement with the quantization questionnaire in addition. From the result of study, the literature discussion program improved the Nature Conservation knowledge of students. For the attitude toward Nature Conservation, the students learned how to respect various kinds of biological lives even more. They improved their environmental sensitivity, and took on a new way of thinking to reform bad living habits to make the environment better. Most of the students can accept the literature discussion program. A few of the students met some problems in study, mainly in ”writing difficulty”, ”disordered communication”, and ”the principle of fairness suffering a setback”. More than 0% of the students liked the literature discussion program.Therefore, proceeding to teach reading on Nature Conservation through discussion leads to good results and popularizes the concept of Nature Conservation. This method of teaching reading can be utilized in more schools in the future.
