E-learning is an educational approach that combines different types of multimedia technologies to ensure better education experiences for students and teachers. Today, it is a popular approach among especially teachers and educators. In this sense, this paper describes a web based e-learning system that was designed and developed to be used in the "Electrical Circuit Analysis" course of electrical engineering education given at Afyon Kocatepe University. The developed system includes many lesson content pages that include content texts and some interactive simulations designed with Flash technology. Furthermore, the system also employs some online communication and assessment tools developed for teachers and students. In order to evaluate its effectiveness, the system was actively used within an experimental evaluation process. According to the obtained results, the developed system improves students' achievements on the course of Electrical Circuit Analysis and provides an effective way in engineering education.
