The tuition-free policy for normal students is an important measure taken by the state under the strategic background of giving priority to education and building a powerful country in education. Students' learning motives reflect their learning status and beliefs in teaching profession, being an important factor affecting their education result and career ability. Based on the actual education of public-funded normal students, our research group selected the tuition-free normal students from five western normal universities as the research object. Empirical investigation is carried out on four aspects: relevant policies, self-factors, educational factors and environmental factors. In view of existing prominent problems, it's proposed that we should follow a policy of strict enrollment, emphasis on the education process and guidance, and focus on the four dimensions of government, society, universities and colleges to help with policy support, service guarantee, education management, self-improvement, etc., and should work together to educate the public-funded normal students who are comfortable and enthusiastic about teaching.
