Background:
The push-pull technology is adopted to establish a mobile learning system and develop the Push-pull Course of Special Topic Mobile Learning of Electric Welding, which includes three parts - (1) the instruction of the electric welding course, (2) the learning of the electric welding course, and (3) the multi-dimensional evaluation of the electric welding course.

Material and methods:
Two classes of the course in the department of engineering science of university of science and technology were taken as the research subjects for the experimental instruction, with 61 students in the Experimental Group and 58 in the Control Group.

Results:
The questionnaire and written information about the students were collected and analyzed so as to explore the influence of “Push-pull Mobile Learning Course of Electric Welding" on the academic performance and attitude.

Conclusions:
The conclusions of this study: (1) the course can significantly improve the students' learning of electric welding; (2) students hold a positive attitude towards the course; (3) the course can facilitate the students' discussions, learning effects and cooperative learning.
