Learning to Analyze Electric Circuitheld atPublic vocational high school 1 Pariaman, teachers still using conventional learning model with whiteboard and markers, this medium was only able to present the instructional in the one direction. It doesn't challenge students to understand instructionally well, so instructional goals not reached optimal.To overcome this,it need to be developed that makes students learn interactivelyand independent.In the form of interactive learning multimedia based on ICT valid, practical and effective.This is Research and Development, with the 4D model that is Define, Design, Develop and Desseminate. Based on the research results obtained data validity of the validator,1 st validator 88.33%, 2 nd validator 93.33%, and 3 th 88.33%, overall is valid. Test practicalities by teacher80.31%, and student 87.50%,overall is practical. The effectiveness test result is 91,89% with practical category. This research has resulted in Information Communications Technologies media isvalid, practical and effective.

This research aims to get web-based learning media with a valid, practical, and effective on subjects the basic computer and network. This web-based learning media designed to improve the understanding of students thus increasing the learning results. This research uses research methods Research and Development (R and D) with 4-D development procedures (Define, Design, Develop, Desseminate). Data analysis techniques using descriptive analysis techniques for describing validity, practicalities, and web-based learning media efetivitas. The results obtained from the research of development: (1) the validity of a web-based learning media declared valid on aspects of media and materials, (2) a web-based learning media practicalities based on the response of teachers and students expressed very practical, (3) the effectiveness of web-based learning media declared effective in improving learning outcomes. Based on the findings of this study it was concluded that a web-based learning media declared valid, practical, and effective way to used as learning materials on subjects the basic computer and network
