Abstract:General Biology is basic discipline in Environmental Science and Engineering,which lays a basis for the specialized courses in this major.As the course involves a wide range of knowledge,traditional "cramming education" cannot attract the interest of students.To meet the needs of talents against the backdrop of "double world-class project",our teaching team applied the"double-cycle teaching mode"of blended teaching in the first class along with ideological education,professional education,innovation and entrepreneurship education in the second class of this course.With this method,major headway has been made in this course.This study is expected to serve as a reference for reform in other relevant courses.
