The purpose of this study was to develop and evaluate a web-based instructional program for a nursing informatics course.

The course subject, nursing informatics, was formed by a computerized instructional module using the website. The program was developed with consideration for the level of competence and knowledge of the nursing student subjects. It was based on 10-steps CAI module developed by Alessi and Trollip(1991). The subjects consisted of 46 undergraduate nursing students taking a nursing informatics course.

Most of the undergraduate nursing students were satisfied with the web-based instructional program, especially with the system features of this program consisting of a system approach and course contents.

This program was very useful for increasing the effectiveness of learning and the motivation of the students.
