This paper examines whether a blended course that introduces lower-level education online learned by students before they come into class and after class online assignments and online discussions enhances student performance for an introductory principles of accounting course over the period 2009-2010. The blended course design includes (1) before-class online quizzes, (2) after-class online homework assignments and online quizzes, (3) after-class comments postings, and (4) company case and project online postings. The regression results show that the above designed blended course improves the student final examination/course performance through in-depth in class activities after controlling for prior GPA, math grade, gender, transfer, homework grade, online quiz grade, and in-class exercise grade.
