Abstract: To develop the influencing factors scale of undergraduates’ learning attitude towards specialized courses and test its validity and reliability. 1044 undergraduates were selected at random and asked to complete the scale, 90 students of which were chosen randomly to complete the self-designed scale after3 weeks. The results showed that: the Influencing Fac- tors Scale of College Students’ Learning Attitude towards Specialized Courses includes three sub-scales of living environment, teacher style and value; the reliability coefficients of them range from 0. 59 to 0. 83 and a repeated test of the reliability finds the coefficients range from 0. 52 to 0. 78. and the confirmatory factor analysis finds that the model has a nice fitting value. The various indices of the Influencing Factors Scale of College Students’ Learning Attitudes towards Specialized Courses have all met the requirements of psycho-metrics in terms of its reliability and validity and thus is worthwhile in scientific research.
