This study investigated the positive impact of a teaching practice on student learning outcomes in an online MBA program. An instructional project guideline was developed to help online students enhance their achieving required learning objectives corresponding to five categories of Bloom's Taxonomy. The course learning objectives are based on primary course standards well-received by the Association to Advance Collegiate Schools of Business (AACSB) for online MBA programs, and student learning outcomes were assessed with a pre-designed assessment rubric. All data were collected from student projects in an online MBA operations management course over the last four-year period. The results of this research indicated the efficacy of the instructional project guideline in: using information technology to enhance personal and organizational effectiveness; helping online students achieve the required learning objective to evaluate a resource allocation and a marketing, production management decision using appropriate quantitative or qualitative tools; assess individual and group competencies in a virtual team as well as producing plans to improve personal and team effectiveness.
