A well-designed syllabus provides students with a roadmap for an engaging and successful learning experience, whereas a poorly designed syllabus impedes communication between faculty and students, increases student anxiety and potential complaints, and reduces overall teaching effectiveness. In an effort to facilitate, streamline, and improve overall syllabi quality, this article proposes a design framework for constructing a learner-centered online syllabus generator system. Based on a learner-centered syllabus template, the proposed framework integrates the widely used system lifecycle approach and the idea of peer review in developing a syllabus preparation lifecycle. Guided by this framework, an online syllabus generator system was created to demonstrate the framework's utility. This online tool enables faculty to easily create, adapt, and share course syllabi, without the inefficiencies, inconsistencies, and time constraints associated with the traditional ways of preparing syllabi. Early results indicate that faculty are highly satisfied with the syllabus generator tool. The majority of the respondents reported that the tool helped them reduce syllabus preparation time and communicate course goals and expectations. (Contains 5 figures.)
