This study compared the effectiveness of different instructional communication methods in a Web-based course on students' cognitive learning, satisfaction, and motivation to complete the course. A total of 174 undergraduate nursing students were selected randomly and assigned to experimental or control groups. Instruments included a demographic data form, two examinations on course material, a course satisfaction scale, and calculation of completion rates. All students received identical didactic Web-based instructional materials. However, type of communication varied among groups. No significant group differences were found for cognitive learning or motivation to complete the course. A significant group difference was found for student satisfaction with the course, indicating carefully planned communication strategies can improve satisfaction. A need for technical support also was evident. More research is needed to determine the best strategies to enhance student learning outcomes and decrease student attrition in Web-based courses.
