To explore the learning effect of mainland students taught by Taiwan professors, this paper collects data through questionnaires and uses the multiple equal part linear regression to analyse the data. This paper explores the influence caused by factors such as the position of the images and the size or density of the word in the textbooks, which is in traditional Chinese character, used by professors from Taiwan. And other factors like the interest of students to the course and the motivation of the course selection are also analysed in this paper. Research results show that: all the typesetting factors and the motivation of the course selection have a great influence on students with poor learning performance. And the interest to the course also has a high impact on students with poor or moderate learning performance. Our research focuses on applying complex computing methods-including fuzzy computing and multiple equal part linear regression-to studies in education areas. It encourages more innovative interdisciplinary researches in the future.
