Semantic Web technologies have immense potential to transform the Internet into a distributed reasoning machine that will not only execute extremely precise searches, but will also have the ability to analyze the data it finds to create new knowledge. This paper examines the state of Semantic Web (also known as Linked Data) tools and infrastructure to determine whether semantic technologies are sufficiently mature for non-expert use, and to identify some of the obstacles to global Linked Data implementation.

"Being able to solve everyday complex problems through communication and cooporation with others are the skills that students need to learn and practice to prepare for the future. Communicating effectively and efficiently with diverse audiences and solving everyday problems are important in a society that is moving at a rapid pace in a Global Market. The ability to solve everyday complex problems is an important and necessary skill for students today. Problem based learning (PBL) provides a learning environment students require to resolve everyday problems while applying previous and learning new knowledge. Cooperative learning, as a part of PBL, allows students the opportunity to communicate ideas and knowledege. As a teacher it is also important to communicate effectively with students to guide the learning process as well as model how to question and reason through a problem.

Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven't learned anything. The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge. There is hope, however. Presenting students' common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it."
