The Internet houses extensive data resources. Most are free and open for public use such as news and informational articles from credible sites. Others such as journals and official publications may only be accessed after registration or for minimal fees. Research can be done at home comfortably and comprehensively.
Going online also has a positive impact on teaching methods and serves as an effective teaching aid as well. Videos of lectures, online modules, and digital presentations can be uploaded and reviewed by students. Even submissions of projects and assignments can be done via email. Forums allow interactive discussion and even debates on certain subjects.
