Through years of teaching practice and full understanding of the current concept of emerging engineering education and the innovation of blended teaching, our teaching team proposes a blended teaching mode of Remote Sensing Principles Course based on the concept of emerging engineering education. This mode is for the problem of learning with difficulty, which is caused by the multidisciplinary synthesis, strong transformation and wide application of remote sensing courses. The practice shows that the blended teaching mode of Remote Sensing Principles Course based on the concept of emerging engineering education can better solve the problem of learning with difficulty and improve students' professional ability and comprehensive quality.

Abstract. With the development of the Internet, online courses like a hurricane swept across the world, teachers consciously or unconsciously are involved in it. In order to make clear the concept and characteristic of online education, this paper, based on the readers' perspective, reviewed the development of the online courses, and summarized the author's own online course construction and application process. It also put forward the teaching staff's confusion about the online course, which will cause people to think, and finally gave some suggestions for the future development of online courses, and these will provide reference for who will construct or teaching on online courses.
