The relationship between teaching and research is a controversial issue in higher education research. Many empirical studies have reported a near zero relationship although academics believe that teaching and research are related in diverse ways. This study focused on how the relationship differs by faculty characteristics (career stage and their academic ability), their affiliated disciplines and each measure of research publication (book, domestic journal and international journal publication), to address the gaps between empirical studies and academics' beliefs. This study found that book and domestic journal publication is positively correlated with teaching quality, while international journal publication is negatively correlated with teaching quality. In addition, the relationship differs by faculty career stage and affiliated discipline. (Contains 5 tables and 2 figures.)
