The e-Learning Courseware Certification service is provided by the Quality Service Center of the e-Learning Network Science Park to distinguish and promote well-designed e-learning course-ware. The e-Learning Courseware Centification program employs a systematic process to evaluate the educational quality of e-learning courseware from the perspectives of content, navigation, instructional design, and instructional media. The results from analyzing 25 e-learning courseware cases revealed that 1) the measurement of the certification program showed adequate reliability and validity, and 2) the certified cases outperformed the uncertified cases in content, instructional design, and instructional media. The research suggests that the development of e-learning course-ware should utilize sound instructional design methods to enhance the learning effectiveness.
