Inquiry Provides a Framework for Learning

"To become independent learners, students must gain not only the skills but also the disposition to use those skills, along with an understanding of their own responsibilities and self-assessment strategies. Combined, these four elements build a learner who can thrive in a complex information environment."

"Learning has a social context: Learning is enhanced by opportunities to share and learn with others. Students need to develop skills in sharing knowledge and learning with others, both in face-to-face situations and through technology."
American Association of School Librarians 

Elearning tools than support the development of these 21st century skills include: journal, discussion forum, wiki, quiz, feedback.
