This study investigates students' motivation in college English learning under production-oriented approach by means of a questionnaire. Forty students in their first-year study participated in this survey. They came from four different disciplines: electronic engineering, automatic engineering, mechanic engineering and power engineering. They were required to fill in the questionnaire at the beginning of the second semester before the teaching reform and at the end of the second semester when the teaching reform was conducted respectively. Our study indicates that students in increasing numbers begin to show great interest in college English learning under the production-oriented approach (POA), and their intrinsic motivation in English learning has been strengthened while at the same time extrinsic motivation shows a tendency of decline. The potential implication of this finding is that POA may be effective in stimulating students' motivation in college English learning.
