Abstract
This study examines through action research whether blended instruction in an upper-level philosophy course in introductory symbolic logic can help undergraduate philosophy students to achieve better learning outcomes than undergraduate philosophy students in a traditional, face-to-face version of the same course. The authors conclude that the change from traditional instruction to blended instruction did have a positive and significant effect on student learning as measured in course grades and student assessment scores for one course learning objective, as well as a positive but non-significant effect on student assessment scores for two additional course learning objectives.
