Abstract: The evaluation of course goal achievement based on the concept of outcome-oriented education is an effective means of teaching evaluation, which is of great significance for the improvement of teaching process and teaching quality. In view of the current teaching situation of electrical engineering courses, the three-dimensional evaluation methods of “test attainment”, “process attainment” and “assessment attainment” are proposed on the basis of improving the existing evaluation methods of course goal attainment in domestic universities and colleges. The method is applied to the teaching practice of electrical engineering to obtain a more comprehensive mastery of students’ knowledge of the course, which provides a reference for the continuous optimization of teaching methods.
