First, among the factors of professor favorability, personal characteristics had a significant positive effect on learning effectiveness, while familiarity had no significant effect. Second, professor favorability had a significant effect on lecture satisfaction. Third, learning effectiveness had a positive effect on lecture satisfaction. Based on these research results, it was recognized that personal characteristics among the factors of professor favorability were important as a way to enhance learning effectiveness, which is the original function of universities, in order to effectively guide foreign students, and it was also found that professor favorability had a synergistic effect leading to lecture satisfaction for the professor.
