Students from two classes of the ISEC program at Baotou Normal University participated in a general education course in environmental science and technology called "BYOD+ Flipped Classroom". Course content is mainly pushed by the platform of Blue Moyun class. Students use their own devices (smart phones) to participate in online learning and interaction of the course. The teaching team uses the mixed method of "BYOD+ flipped classroom" for teaching design and implementation. Student questionnaires show that students' knowledge has expanded, survey and other curriculum activities have increased, and their grades have improved. The data of group interview shows that students have a good learning experience of this learning mode and a positive view of the teaching mode of "BYOD+ Flipped classroom". The average score of students who implemented the "BYOD+ flipped classroom" hybrid teaching method was 85.18% (2017), while the average score of students who implemented the traditional teaching method was 81.39% (2016). In 2017, the average course evaluation score of "BYOD+ Flipped Classroom" students was 96.8/100, compared with 93.74/100 under the previous traditional teaching model. It can be seen from the group interview that, first of all, students have obtained a better learning experience, and secondly, students' attitude towards the ecological environment has changed.
