The invention relates to the technical field of robot education, and provides a teaching quality evaluation method and device. The teaching quality evaluation method is applied to an evaluation server. The teaching quality evaluation method comprises obtaining a first evaluation result on the robot teaching quality and made by professional teachers from the point of instructors from teacher clients; obtaining a second evaluation result on the robot teaching quality and made by robot experts from the point of developers from expert clients; obtaining a third evaluation result on the robot teaching quality and made by students from the point of participants from student clients; carrying out weighted calculation on the first evaluation result, the second evaluation result and the third evaluation result; and obtaining the total evaluation result on the robot teaching quality and saving the total evaluation result to a memory cell of the evaluation server. The total evaluation result on the robot teaching quality and obtained based on the above method can reflect the teaching quality of robot assistant instruction objectively, comprehensively and accurately.
